What is cruise control? This is a special system that automatically maintains the speed set by the driver. Thanks to cruise control, long journeys are less tiring and the driver can relax a little by taking their feet off the pedals.
Cruise control is more common in America than in Europe, since the United States has fairly long distances, and the roads themselves are much wider. The constantly increasing traffic leads to the fact that the functions of conventional cruise control are becoming less useful every day, so adaptive cruise control systems have replaced simple cruise control. The latter are distinguished by the fact that they allow you to follow the vehicle in front, while constantly maintaining a safe distance and a given speed. In my article today, I will talk about how cruise control works, as well as the main advantages and disadvantages of adaptive cruise control.
How cruise control works
This system has many useful functions, in addition to being able to control the speed of the vehicle. For example, some systems are capable of accelerating or decelerating a car by one kilometer, all you need to do is press a button. Therefore, by pressing the button five times, you will accelerate by 5 km / h. To stop the automatic cruise control, just click on.
Cruise control dashboard
It is easy to guess that the "On" and "Of" buttons turn on or off the cruise control. By pressing the On button, you will not feel anything, just the system will go, as they say, into a "combat" state and will wait for other buttons to be pressed. Key "Off" - turns off the system, even during its operation. It should be noted that some cruise control systems do not have these buttons at all, turning on occurs after pressing the Set button, and deactivation after pressing the brake pedal.
The Set / Accel buttons let you set the speed you want. To do this, you need to accelerate or reduce your speed to the value you need and press this button. Each second press will accelerate the vehicle by 1 km / h. After the driver has pressed the brake pedal and reduced the speed, you can press the Resume button, it will return the car to the speed it was before braking. Coast - an analogue of the brake pedal, after pressing this button, the car will slow down in the same way as if the driver took his foot off the gas. The brake and clutch pedals are equipped with a switch that disables cruise control, so if necessary, the driver can deactivate the system by simply pressing one of these pedals.
Acceleration and braking by means of the cruise control system
With this system, the driver can control the vehicle speed in the same way as using the throttle. However, it should be noted that the cruise control operates the throttle valve pneumatically and not by depressing the pedal. and the driving speed is controlled by the throttle valve by limiting the amount of air entering the engine.
Cruise control throttle control
The throttle valve is controlled by two cables that are connected to the hinge that moves the throttle valve. One of these cables is connected to the gas pedal, and the other to the pneumatic actuator. When cruise control is on, the pneumatic actuator moves the cable that is connected to the throttle control rod, in addition, it pulls the cable connected to the gas pedal, which allows the pedal to move up and down without hindrance, even when the cruise control system is on.
Some vehicles use pneumatic actuators in which the engine acts as a vacuum blower. These systems use a medium sized electronically controlled valve that regulates the vacuum in the diaphragm. Similar to a brake booster that provides power to the braking system of a car.
Cruise control management
The brain center of the cruise control system is miniature, which is usually located in the engine compartment or behind the dashboard. As I said, it connects to the throttle control and several sensors.
Cruise control scheme
A high-quality cruise control system is able to quickly and efficiently accelerate the car to the speed required by the driver, after which it is able to maintain it with minimal deviation, regardless of the vehicle's load and the steepness of the rise. Speed control is carried out according to the classical principle. The cruise control system adjusts the throttle position and therefore needs sensors to tell it the vehicle speed and throttle position. The system also monitors the pressing of buttons and pedals, and then makes adjustments to the speed, instantly reacting to the need to turn on or off.
Many modern cruise control systems use the proportional-integral-derivative principle ( Proportional-Integral-Derivative - PID). I will not go into the details of all these "three-storey" definitions, because in order to understand this principle it is necessary to understand what: the integral of speed is distance, and the derivative of speed is acceleration.
The PID control system works with these three factors - proportional, integral and derivative, calculating each of them separately and adding them to obtain the throttle position.
We have already discussed the proportional coefficient, now I propose to talk about the integral. The integral factor is based on the time integral of the vehicle speed error. Translated into "human" language - the difference in the distances that the car actually covered and the distance that it could travel, provided that the movement would occur at the required speed, which is calculated for a certain period of time. This coefficient is responsible for the acceleration of the car when driving downhill, in addition, it helps to achieve and maintain the speed required by the owner. For example, a car starts moving downhill and starts to slow down. After that, the proportional system starts to open slightly wider, but the car can still slow down. After a moment, the integral control gives the command to open the throttle even more, this is due to the fact that the longer the vehicle moves below the set speed, the greater the distance error will be received by the cruise control system.
Now it's time to discuss the final coefficient - the derivative. As we said, the derivative of speed is acceleration. Thanks to this coefficient, the cruise control is able to instantly react to any changes on the road, for example, such as hills and descents. The principle is that if the car slows down, the cruise control notices this in time until the moment when the speed drops significantly and instantly reacts to this by opening the throttle valve.
As I promised, a few words about adaptive cruise control.
Adaptive cruise control is a more advanced system capable of automatically adjusting the speed of the vehicle, taking into account, in addition to the speed mode, also maintaining a safe distance to the vehicle in front. The adaptive cruise control is equipped with a radar that is installed just behind the grille. The radar constantly sends a signal, which actually determines the need to accelerate or slow down the car, based on the speed of return of the signal sent forward.
Adaptive cruise control is very similar to conventional cruise control, since it, like its less "advanced" counterpart, is able to maintain the speed set by the driver. However, compared to conventional cruise control, adaptive cruise control is capable of automatically adjusting the speed to maintain an optimal safe distance between vehicles in the same lane.
This is achieved, as you already know, using a radar sensor, longitudinal controllers and a digital signal processor. In the event of a decrease in the speed of the vehicle in front, or the occurrence of any other object, the system immediately sends the appropriate signals to the engine and braking system for subsequent immediate deceleration. After the obstacle has moved to a safe distance and there are no obstacles on the road, the adaptive cruise control system will begin to set the speed set by the driver again.
The Autocruise radar system, which operates at 77 GHz, has a range of about 150 m, and is capable of operating correctly at speeds from 30 to 180 km / h.
Today, adaptive cruise control is one of the most promising actively developing systems of its class, successfully used in the automotive industry in many European countries. The system not only contributes to increased driver comfort, but also prevents the possibility of collisions, increasing the level of safety for all passengers. Modern adaptive cruise control systems are capable of giving audible as well as visual signals in the event of a collision hazard. Moreover, they are able to make their own decisions in the event of a driver's delay and make evasion or emergency braking when necessary.
Without cruise control, long distance trips would be tiring and fatigued. We will tell you: what it is and what it is for, how to use it, what is the difference between passive and adaptive.
What is it and how to use it?
Cruise control is a device that maintains a constant vehicle speed by automatically increasing or decreasing throttle on its own without driver participation... Most often, it is used while driving on highways. The driver sets the optimal speed with which he is going to drive, and the system itself presses or releases the gas pedal.For example, we set up the system at 100 km / h (additionally adjusts within plus or minus 5 km / h) in order to keep the highway restriction up to 90 km / h plus the permitted 20 km / h and not be fined. The driver only has to steer. The system can slow down on slopes or when approaching a slow vehicle. After passing it, it will automatically dial the preset value.
In urban conditions, where the speed of the car is unstable, it is not needed. For safety reasons, the cruise is disabled as soon as you press the brake pedal, and it is inactive when driving less than 40 km / h.
For ease of use, the cruise buttons are located directly on the steering wheel and consist of 5 main ones: On, Off, Set \ Accel, Resume, Coast. Plus a brake pedal that automatically disables the system.
With the on / off buttons everything is clear. When you press the Set / Accel button, the cruise control will lock the speed at which you are walking this moment... If you press this button again, it will increase by 2 km / h. If you slowed down, then to restore the lost speed, you need to press the Resume button. If you hold down the Coast button, the speed will decrease.
What is an adaptive cruise?
There is an adaptive type system that monitors the speed of the vehicle in front or the road relief, knows where there will be turns, descents, difficult sections. Depending on these conditions, it automatically adjusts your speed and maintains a safe distance between the two cars. Those. in fact, it is the possibility of autonomous movement of the car with minimal driver intervention. In some cars, it is capable of bypassing slow cars or changing lanes.This opportunity will appear thanks to the installation of a radar and a digital processor. This type is called active. Traditional cruise control is considered passive and does not automatically adjust the speed; you must do this yourself.
Let's look at an example of how active cruise control works on Mercedes cars. It works when they are attached to the car, and with the help of a video camera aims at the license plate of the leader car. Then your car will follow the leader as if tied, if he does not change the lane, and the road is not a mountain serpentine with tight turns.
If the vehicle in front slows down, the system sends a signal to reduce speed. When the road is empty, it gives a signal to restore speed. If you have a passive cruise, then you yourself must slow down and then also independently restore the speed to the set one.
Active cruise control works at speeds between 30 and 200 km / h. And the main condition for its use is you must never remove your hands from the steering wheel otherwise it will shut down. There are also options when the car follows the road markings and moves within the lane, rather than looking for another car. In fact, adaptive cruise is a first-level automatic driving system without a driver, but which still requires participation in the driver's process.
Video review by example
Active cruise control is designed to help avoid a collision with the vehicle in front. If the system does not have time to reduce the speed and there is a possibility of a collision, then it gives the driver a signal to apply the brakes or move away from the collision. In advanced systems, it is capable of self-braking without driver intervention.
In the car. Meanwhile, this is an old system, which previously could only maintain the speed of the car, and the driver did not have to hold the gas pedal. This system provided additional convenience and comfort when driving on highways and highways. As a result of using cruise control, the driver is less tired while driving. Also, in theory, this helps to reduce fuel consumption, since the engine runs evenly when the system is used, and its rpm does not jump.
What is cruise control in a car for?
This system is needed to provide additional convenience when traveling long distances. For example, if a driver needs to get from one city to another, having covered 500-600 kilometers, then by car without this system he will have to hold the gas pedal for 5-6 hours (depending on the speed of movement), which is actually equal to holding the right foot in an uncomfortable position. During the entire travel time, you want to change the position of your leg, but this cannot be done. It seems that this is a trifle, but keeping the gas pedal for 5-6 hours is actually very difficult.
By activating the cruise control function in the car, the driver can afford to release the accelerator pedal. The system will supply fuel to the combustion chambers not through the gas pedal, but through special pneumatic drives. The driver will be able to adjust the speed of movement using the buttons that are located on the steering wheel (usually there are 5 buttons).
System management
Now that we understand what it is - cruise control in a car, we can figure out how it works. Usually there are 5 buttons on the steering wheel to control this system:
- On / Off button that activates and deactivates the system.
- Switch for fixing the speed mode and increasing the speed. That is, after accelerating to the required speed, the driver can fix the current speed with a switch and release the accelerator pedal. Subsequent presses on this button will increase the driving speed by 1 km per hour.
- If, while using the cruise control, the driver had to quickly accelerate or brake by pressing the gas or brake pedal, then the parameters of this system are reset. To quickly activate cruise control and return to the previously set speed, the driver must press the Resume button.
- Coast speed reduction button. Each press of the button decreases the driving speed by 1 km. In some models, the step of decreasing and adding speed is 1.5 km.
- The Cancel button deactivates the system.
Depending on the car model, this system can be represented by other buttons, the step of accelerating and decelerating may differ. But the principle looks exactly as described above.
Views
There are several types of cruise control in the car. What does passive or active type mean? In the first case, the driver can only set the speed of the vehicle. However, the second type involves the use of sophisticated electronic devices that scan the space in front of the machine, which opens up additional control options. vehicle depending on traffic conditions.
Passive type (PPC)
As we have already found out, passive cruise control allows you to maintain a given speed, which is convenient for long trips over long distances. Due to the constant high-speed operation of the engine, fuel economy is provided.
The control is deactivated when the driver is slightly pressed on the gas pedal. The design of such a system has a special pneumatic actuator that regulates the flow of the air-fuel mixture into the combustion chamber through the throttle valve. This eliminates the need to use the gas pedal.
Active (or adaptive) type
Adaptive cruise control is an improved version of the active type. In addition to the ability to maintain the speed limit without pressing the gas pedal, cars with adaptive cruise control can calculate the distance to the vehicle in front, and also reduce or increase speed depending on the situation on the road. That is, if the system determines that the distance to the vehicle in front is decreasing, then the system also slows down. The deceleration is carried out until the time between the cars, in the opinion of the system, becomes optimal. If the sensor stops seeing an obstacle in front, then the car picks up speed and keeps this speed limit.
Security
The adaptive setting of cruise control on the car is quite smart, it provides not only comfort when driving on highways and highways, but also the safety of the driver who can relax too much on the road.
In addition, this system can produce not only emergency braking, but also evasive maneuvers. This greatly increases driving safety, and often such systems preserve the life of people and the integrity of the vehicle itself in various situations on the road.
Note that adaptive (or active) cruise control is closely related to the operation of ABS and ESP systems (stabilization and anti-towing systems), and if at least one of them stops working, then cruise control cannot be activated either.
Dynamic type
In addition to adaptive and passive cruise control, there is also a dynamic one. It is one of the varieties of the passive type. A feature of this system is the control of engine operation, which saves fuel and engine resource.
For example, when climbing a hill, the system slows down and slows down, which protects the motor from unnecessary loads. Also, the speed is reduced when there are any problems with the engine and when the car enters corners. After cornering, the previous speed is restored.
Now we figured out what it is - cruise control in a car. Let's define its main advantages and disadvantages.
pros
The benefits of this system are clear to every driver. First of all, this is convenience when driving and a decrease in stress on the back due to the absence of the need to keep your foot on the gas pedal. Some drivers cite fuel economy as a virtue of such a system. In theory, savings are achieved by ensuring the uniformity of the engine and the absence of drops in fuel injection. In addition, if adaptive cruise control is installed, then it also provides additional vehicle safety.
disadvantages
The main disadvantage is the high cost of the system. Cars with cruise control systems are expensive and out of reach for most consumers. However, cars with conventional passive systems are already available to the middle class of consumers.
If you believe the reviews of some drivers who actively use this system, fuel economy is completely absent, and in some cases there is even increased consumption. Another serious drawback is the unsafe use of the system due to the fact that the driver can relax too much while driving the car. Constantly keeping your foot on the gas pedal, you will not be able to relax much.
The next disadvantage is the impossibility of using the system on roads with frequent descents and turns, as well as on highways with heavy traffic. There is no need to talk about using the system in the city at all.
Many drivers do not recommend using this system on the road after or during rain, as the driver needs to feel the car when braking. Otherwise, it may lead to an accident. This system is suitable only for those drivers who often travel from city to city. In urban traffic, the function is practically useless, since there are no long sections of the highway in the city where it would be possible to keep a stable speed for a long time.
Conclusion
Now we finally understand what it is in a car - cruise control. Such a system is really useful and necessary - it should be in every car. Gradually, such systems appear in cars of the middle and even budget class, but so far these are just passive varieties. In addition, this system can be installed even on a car in which this technology is not provided by the manufacturer. Special installations are sold at car dealerships.
On this you can put an end. We figured out what it is - cruise control in a car. The technology is useful in some cases, but you shouldn't get carried away with it, since the driver shouldn't lose concentration on the road.
For many, cruise control on mechanics may seem like something fantastic, but if you try, you can install such an additional function on your own car. The only thing to think about right away is whether or not you need cruise control on your car? After all, although in general this additional function greatly facilitates the process of driving a car, it also has its drawbacks.

What you need for installation Installation process Is it worth using cruise control on a car: advantages and disadvantages of the function.
Is it possible to install the cruise control on the mechanics: we deal with the technical nuances.
Those car enthusiasts who are wondering if there is a cruise control on the mechanics most likely met this function only on cars with an automatic transmission. Indeed, this additional function is mainly used only on cars with automatic transmissions, on which it is possible to install it in the normal mode.
In this case, the procedure for connecting the device will not be difficult, since the car owner will only have to install it on provided by the manufacturer a place.
As for cars running on a manual transmission and on which the possibility of installing cruise control was not provided, then a universal device can be manually installed on them.
IMPORTANT! When buying a cruise control for a car with mechanical box, give preference to German manufacturers whose devices are highly reliable. This will allow you to avoid unexpected breakdowns of the cruise control from overloads that may arise due to incomplete compatibility with the car.
Technically, a similar procedure provides for the additional installation of a bracket and an additional cable to the accelerator pedal, with the help of which it will be possible to control the speed of the car. Cruise control on the mechanics also provides for the installation of a device control button at the bottom of the deflector.
However, often, this button turns off after each pressing of the pedal (for example, when overtaking), which is why the cruise control has to be activated again.
Will the manual transmission cruise control work fully?
The operation of the cruise control on the mechanics is practically no different from its operation when installed on a car with an automatic transmission.
However, in this case, there may also be one drawback: when trying to go uphill with cruise control on, the driver will not be able to automatically downshift.
Because of this, if the driver is driving in the 5th gear of a manual transmission, then without additional pressing of the gas pedal, he is unlikely to be able to completely overcome the entire rise.
In such a situation, another feature of the cruise control manifests itself - if the car's speed decreases (which happens when it is impossible to go up the slope), the device is automatically turned off at 40 km / h, so the driver will have to resort to mechanical control of the gas pedal in any case.
IT IS IMPORTANT! If the cruise control has a RES button, the speed can be reset by pressing it twice. In its absence, the speed can be reduced by depressing the gas pedal and fixing the new speed using the cruise control start button.
The process of connecting the cruise control to the mechanics when it is not provided by the manufacturer.
Before proceeding with the installation of the cruise control, the car owner must make sure that all technical units of his "iron horse" are in good working order, and also install good tires on the car. This is due to the fact that in the presence of such malfunctions it is very dangerous to allow the car to go under automatic control. If everything is in order, the driver will not endanger himself by driving on the cruise control.
What you need to install
To complete the work, it is important to prepare in advance:
curly screwdriver;
scissors or an awl (the main thing is that they are very sharp);
nut head;
wrench;
a set of self-tapping screws (screws can also be used);
cable for connecting to the accelerator (it can also be included with the device);
universal cruise control.
IMPORTANT! If your car has an accelerator pedal position sensor, then you will need to purchase an additional bracket for it, which you will also have to put on with your own hands.
Installation process
In general, all the work on installing the cruise control on the mechanics will take you no more than an hour, however, you should allocate time for checking the work, as well as eliminating possible malfunctions. In general, the work consists of the following sequential actions:
Choosing a place for a new device. Often, motorists attach it near the fuel filter, which also allows the cruise control to be connected to the brake hose. You can choose another place for it, the main thing is that it is dry, and you can freely bring the cable from the accelerator to it (if there are strong bends in the cable, you will not be able to control the speed).
IMPORTANT! If you cannot run the cable from the accelerator in such a way that there are no bends on it, you can use a regular fishing reel, along which it will bend freely, without breaking or damaging other mechanisms of the car.
We connect the second cable to the accelerator, but do not rush to cut it. First, install the bracket on the gas pedal position control sensor, and only then measure the required length of the cable and cut it off. The other end of the cable can then be connected to the cruise control device.
To connect the cruise control to the car, you must first find the tachometer connection wires, to which you need to connect the new device. The tachometer wire must be connected to the green wire that goes from the cruise control unit. The red wire of the device is intended for connection to brake lights.
Install the cruise control activation / deactivation button. To connect it, we connect a gray double wire. For full operation of the button and the device, be sure to stretch the mass that goes along the black wire.
The cruise control handle must be installed on the steering wheel of the vehicle, for which it will have to be disassembled. If your car has airbags, they will also have to be removed for a while. We install the handle on the steering wheel and assemble it back, not forgetting about the airbags.
We check the operation of the cruise control. To do this, we recommend that you drive along an empty road where there is no traffic. It is rational to do a trial activation of the device at a low speed (but above 40 km / h), while being ready for the need to control the accelerator pedal if the device suddenly does not work.
Is it worth using cruise control on a car: advantages and disadvantages of the function.
The principle of operation of the cruise control function is that the system of the device automatically maintains the speed set by the driver, without requiring mechanical action of the foot on the gas pedal.
To activate the cruise control, the driver just needs to press a button on the device, and immediately after that he will be able to take his foot off the pedal and enjoy the smooth speed of the car, which will not change even when the topography of the road changes.
But this does not mean that the driver will not be able to use the pedals when it is necessary to overtake or stop. All this is quite possible, and even more - after a forced acceleration or braking, the car will still return to the same speed that was set on the cruise control.
IT IS INTERESTING! Modern cruise control systems are equipped with more than one on / off function button. In addition to it, the SET button can be installed, a pair pressing of which will allow the driver to double the speed of the car as quickly as possible, while not touching the gas pedal with his foot.
In general, the advantages of this additional function on a car with a manual transmission include the ability to relieve stress from the leg during a long trip that does not require dynamic car control. Thus, driving on a long and unloaded track, the driver really gets a chance to rest.
However, the rationality of the cruise control on the mechanics is only if the car owner constantly travels out of town on unloaded roads. In urban conditions, there is practically no point in installing cruise control, since the driver will constantly press the pedals with his feet.
We hope you were able to answer the question for yourself whether it is worth installing this additional function on your car, and you will be able to clearly explain to others what cruise control is on the mechanics and how to install it.
Many drivers are aware of the somewhat uncertain condition when they have to drive at the same speed for a long time on an empty or almost empty road. Gradually, there comes a feeling of internal inhibition and dullness, and when an unexpected obstacle or hindrance appears on the road at this moment, the driver often does not have time to properly respond to changes in traffic conditions. In such a situation, adaptive cruise control can be very helpful.
A bit of history
The first system recognized as cruise control appeared in America in the middle of the last century, which is not surprising. There you come across quite long sections of the road, free from other cars, on which you need to move at a given speed. In fact, such conditions must be recognized as ideal for the operation of such a device as cruise control.
Over time, it improved, the principle of speed control and maintenance, used on the first systems, received further development, resulting in adaptive cruise control, first installed on Mercedes-Benz in 1999.
And what is it all about, what is cruise control for?
About the so-called cruise control system. Its task - in the simplest version, used even on the first samples of such a technique - is to maintain the speed set by the driver. How cruise control works is easy to understand. It is characterized by the fact that the principle of operation coincides with the actions of the driver - the device changes the position in which the throttle valve is located when deviations from the driving mode set by the driver occur.
For example, on an uphill, when the speed is slowing down, the cruise control will additionally open the throttle, and when descending, on the contrary, it will close the throttle, reducing the speed. The throttle position is changed by signals from the electronic unit thanks to the special mechanics of the drive system.
The question is whether cruise control is needed, if not considered provocative, then it is quite close to this. Of course, such a device does not belong to the category of mandatory and necessary car devices, such as a gearbox or a clutch, it is quite possible to do without it, but it greatly facilitates the driver's work. This is especially true for truck drivers who have to move for a long time at the same, sometimes rather low, speed. In such cases, there is no need to think about how to use the cruise control - the drivers set the required speed, and the system maintains it, thereby facilitating the driver's work.
But to ask the question whether cruise control is needed in such a somewhat primitive form, as described above, would be quite appropriate. And a kind of answer has already been received for it - now new systems have been created, including adaptive cruise control, which make it possible to implement much more functions when driving a car. In this case, mechanics have to give way to electronics.
New generations, new opportunities and new requirements
Described earlier Cruise control, the so-called passive, provides the driver with a limited list of additional options. Improving this system, various automakers have created their own options for their implementation.
Of these, the following can be noted:
- Radar Cruise Control - manufactured by Toyota;
- Preview Distance Control - Mitsubishi;
- Distronic - Mercedes-Benz;
- Adaptive Cruise Control - Volksvagen, Audi, Honda.
These systems already represent the next generation - adaptive cruise control. Its characteristic feature is that it is not passive but active cruise control. With its help, you can not only maintain and control the set speed - under its control, the car independently brakes and accelerates.
To perform these functions, adaptive cruise control includes:
- a sensor used to monitor speed and distance;
- electronic control controller;
- devices that execute the required commands from the controller.
To understand what intelligent cruise control is for and how it works, just look at the figure below: 
In this case, not only the speed is monitored, but also the distance between the moving cars, for which the active cruise control of the car going behind irradiates the front car and, according to the reflected signal, sets the distance between them. If it decreases, then the second car begins to drop its speed, if it increases, then it accelerates, remaining within the speed set by the driver.
Active cruise control can be equipped with two types of sensors:
- laser;
- radar.
The laser sensor is cheaper, but its efficiency depends on the external conditions, fog or rain will adversely affect its performance. Radar is not subject to such influences, but its price is higher.
What else can he
It is worth touching on the additional features that cruise control provides. In addition to determining the distance between vehicles, calculated from the delay time of the reflected signal, the system is able to determine the speed of the vehicle in front, for which the change in the frequency of the reflected signal according to the Doppler effect is used. 
Dynamic control - tracking the parameters of the movement of the vehicle in front, supplemented by the control of its position on the road, i.e. the location of the front car relative to the rear on the road.
How to use cruise control
It is generally accepted that cruise control is operated using the steering column switch.
As an example, the following illustrations show these controls: 
When organizing such a control system, it becomes intuitive how to use the cruise control. Initially, you must turn on the system. Then, as the movement starts, when the desired speed is reached (in the range from thirty to two hundred km), it is entered into the system memory and will be maintained. The required distance is set by moving the corresponding slider. All set driving parameters for driver control are displayed on the instrument panel, as well as additional indicators in the form of luminous LEDs and special pictograms.
The set speed value can be increased / decreased with the switch. This information on how to use the cruise control is enough to set safe driving conditions for the car thanks to the well thought out control system.
Although cruise control is not an essential part of the vehicle's equipment, it contributes to improving driving safety and providing additional comfort while driving.
