8.23. Antiblocking system of brakes (ABS)
The antiblocking system prevents blocking of wheels at sharp braking. Thanks to it the car at full braking remains operated. The system consists of the hydraulic block of a regulator and 4 wheel gauges. The regulator block contains the electronic control device (ECU), hydraulic electromagnetic valves and the pump with an electric drive. Electromagnetic valves cope block ECU which receives signals from 4 gauges established on each wheel of the car which supervise speed of rotation of each wheel. Comparing these signals, block ECU can define speed of the car. At the expense of comparison of speed of separately taken wheel with average speed of the car the management block defines a condition of blocking of a wheel. When the wheel comes nearer to blocking, pressure of a brake liquid is too high, therefore pressure in a support decreases on a signal of the block of management. It occurs until the wheel again will not start to be accelerated. Then valve are closed again and created by a pedal of a brake pressure starts to affect repeatedly. However value of pressure in a brake contour of this wheel not above the general pressure in system. Work ABS at sharp braking repeats on each wheel until the effort or the car is made a pedal will not stop. At any malfunction in system ABS there is its switching-off. Control lamp ABS on the panel of devices in this case lights up and the brake system works in a usual mode. |
