Anti-blocking system of brakes (ABS) Anti-blocking system of brakes The anti-blocking system of brakes (ABS) operates 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:
The anti-blocking system of brakes works at information basis from four sensors, transferred to the ABS block. The system operates each wheel separately and reduces pressure of liquid in that wheel brake mechanism which wheel starts to be blocked. Under normal conditions the standard brake system carries out braking till blocking of the wheel found by the ABS control unit. When the ABS control unit finds wheel blocking, it operates each valve for increase or pressure reduction. The ABS control unit defines frequency of rotation and norm of delay of each wheel on the basis of information from sensors of frequency of rotation of a wheel. When braking frequency of rotation of a wheel decreases and the ABS block defines a difference between speed of the car and frequency of rotation of a wheel. If delay of some wheels exceeds expected value, the ABS block defines the beginning of blocking and opens the corresponding electromagnetic valves to reduce pressure of brake liquid. Thus frequency of rotation of a wheel increases and the electromagnetic valve of dumping of pressure is closed and there is an increase in pressure of brake liquid in the working brake cylinder of the corresponding wheel. 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. |
