Overcoming long distances on the car requires increased attention from the driver, so with frequent country trips it is better to establish cruise control. The main purpose of this device is to support a certain speed of the car and its adjustment (decrease or increase) in some cases.

The acquisition of cruise control will be justified when moving on the highway, in the city, where the speed of the cars changes, the system will not be useful. If the arrow on the speedometer does not reach 40 km / h, then the control will simply turn off, it works in two modes - passive and adaptive.

Features of cruise control

The system is operated using five buttons built into the steering wheel panel: • On - on. • Set / Accel — sets the speed limit based on the vehicle that is currently moving. A second press raises the mark by 2 km / h. • Resume - restore the speed to the previously set value. The button can be useful, for example, after braking. • Coast - reduction of previously set speed parameters. • Off — turns off.

In addition to the control keys, a mini-computer is built into the machine, to which the choke and the necessary touch panels are connected. With proper operation using the equipment, you can quickly and smoothly pick up the desired speed, and it will be held in any case, even if the road has slopes or climbs. So is the work of passive cruise control.

The uniqueness of adaptive (active) cruise control

Leading car market companies are working on a new system - adaptive control, which will be used to analyze the speed of the vehicle ahead and make further adjustments to the movement of the car with the established cruise until the safe distance between vehicles is reached. In addition to the existing equipment, in this case, a radar and a digital signal processor are built in.

As an example, consider the frequent situation on the road. At the moment when the driver is attached to a car, the number of the leading car is recorded on the video camera. Binding is carried out until both participants are in the same lane. The speed of the second car is completely dependent on the movement ahead of the driver - the cruise control accurately tracks all changes and shifts the speedometer in the direction of decreasing or increasing.

Manufacturers are talking about planning the release of models whose behavior will depend on road markings, and not on other cars.

The main features of the adaptive cruise control: • Operation within 30–200 km / h. • Turn off the system in case of removing hands from the steering wheel.

Thus, using cruise control, it is possible not only to facilitate travel over long distances, but also to avoid collisions with other road users.
