Anti-lock brakes

Anti-lock brakes (ABS) controls the pressure in the brakes of all four wheels when braking in dangerous (slippery) road sections, preventing the wheels from locking. The ABS system offers the following benefits:

- It allows a high degree of confidence to go round an obstacle, even in the event of emergency braking;

- It allows you to stop the vehicle during emergency braking with the preservation of controllability and stability on the road, even at a curved trajectory.

In the event of a fault diagnostic function and the function of the emergency mode of operation, included in the system, provide ease of use and maintenance.

Integrated control unit ABS (HESU), consisting of the ABS hydraulic unit and the electronic control unit ABS assembly receives signals of the vehicle speed, road surface conditions and the movement direction of the wheel speed sensors.

On the basis of these signals the electronic control unit determines the optimum speed of the wheel.

Electronic brake force distribution (EBD)

The use of electronic brake force distribution in comparison with the installation of the proportional valve provides an ideal distribution of pressure in the front and rear brakes. As a result, markedly increases the effectiveness of the braking and blocking of the rear wheels is prevented.
