12.2. Anti-blocking system of brakes

The anti-blocking system of brakes operates (ABS) pressure in a hydraulic drive of brakes of each wheel separately and reduces pressure of liquid in that wheel brake mechanism which wheel starts to be blocked.

ABS carries out the following functions:

Improvement of stability of driving at a detour of obstacles even in the course of braking.

Reduction of a brake way at intensive braking at preservation of stability and controllability of the car even when passing turns.

The control system of draft is intended for increase in draft at acceleration and movement in turn. The system defines optimum frequency of rotation of wheels and to a wheel which in a certain situation rotates quicker, the reduced torque is transferred.

The incorporated control unit (HECU) receives signals about speed of the car, the direction and road conditions from sensors in wheels and a steering column. On the basis of these signals the control unit defines optimum frequency of rotation of a wheel. As the system is a variable, the control unit can define, depending on traffic conditions that some accelerated rotation of a wheel is favorable (thus, rectilinear acceleration) increases or fast rotation of a wheel is unprofitable (at movement in turn).

The system is automatically ready to work every time after engine start, but can be switched off manually by the TCS switch.

EBD (Electronic distribution of brake effort)

EBD is in addition applied instead of a pressure regulator ideally to distribute pressure to lobbies and back brakes, for prevention of blocking of back wheels at intensive braking.
