GENERAL INFORMATION

On the cars equipped with anti-blocking system of brakes at inclusion of ignition on a combination of devices the lassie of ABS lights up for short time.

The anti-blocking system prevents blocking of wheels at sharp braking. Thanks to it the car at complete braking remains operated.

The system consists of the hydraulic block of a regulator and the 4th wheel sensors. The block of a regulator contains the electronic control device (ECU), hydraulic electromagnetic valves and the pump with an electric drive. Electromagnetic valves cope the ECU block which receives signals from the 4th sensors established on each wheel of the car which supervise speed of rotation of each wheel. Comparing these signals, the ECU block can define speed of the car. At the expense of comparison of speed of separately taken wheel with average speed of the car the control unit defines a condition of blocking of a wheel. When the wheel comes nearer to blocking, pressure of brake liquid is too high, therefore pressure in a support decreases on a control unit signal. It occurs until the wheel again will not start to be accelerated. Then the valve are closed again and created by a brake pedal pressure starts to affect repeatedly. However value of pressure in a brake contour of this wheel not above the general pressure in system. ABS work at sharp braking repeats on each wheel until the effort or the car is made a pedal will not stop.

At any malfunction in ABS system there is its shutdown. The control lamp of ABS on the dashboard in this case lights up and the brake system works in a usual mode.
