If, when the car is braking, there is a sharp decrease in the speed of rotation of one of the wheels, which indicates the beginning of its blocking, the sensor installed on this wheel sends a signal to the electronic control unit. which gives a control signal to the corresponding solenoid valve of the distribution valve body, which acts in such a way as to stop the further increase in fluid pressure in the brake mechanism of this wheel or reduces it until the maximum reduction in the circumferential speed of the wheel without blocking is ensured. After that, brake fluid pressure. supplied to the brake mechanism of the wheel, increases and the control cycle is repeated.
During braking of a vehicle with an active ABS system, such regulation cycles can be repeated at a frequency of up to ten cycles per second.
In the event of a malfunction of the ABS system, a warning lamp on the instrument panel lights up, the vehicle is braked in the usual way, and full efficiency is ensured by the pressure regulator.
