6.1.15. Anti-blocking system of brakes (ABS)

The anti-blocking system of brakes (ABS) operates pressure in contours of brakes of all wheels for prevention of blocking of wheels at heavy braking. ABS provides:
– controllability the car at emergency braking;
– a car stop at emergency braking without leaving from the chosen trajectory of movement.
At failure detection in system diagnostics of malfunction and inclusion of a mode of safety is provided, the brake system works as standard.
The hydraulic and electronic control unit receives signals of sensors of speed of the car, a condition of a paving, the direction of movement and frequency of rotation of wheels.
The electronic control unit defines optimum frequency of rotation of a wheel.

Electronic system of distribution of brake efforts (EBD)
Application of electronic system of distribution of brake forces in comparison with installation of the proportional valve provides ideal distribution of pressure in contours of lobbies and back brakes. As a result efficiency of braking considerably raises and blocking of back wheels is prevented.

Advantages of electronic control
Functional improvement of parameters of the main brake system.
Compensation of various factors of coupling a wheel with the road.
Exception of installation of the proportional valve.
Instructions on malfunction by means of a control lamp.
