ABSTRACT:
An electronic regulating system for regulating the supply of pressure medium to each brake cylinder of a vehicle having a plurality of wheels thereby preventing spinning of the wheels upon starting and locking of the wheels upon braking, comprises wheel speed sensors which detect the rotation of the wheels and which produce signals indicative of the individual rotational speeds of the wheels, and an electronic control unit which monitors the individual rotational speeds of the wheels and which controls the supply of the pressure medium to the brake cylinders based on the individual rotational speeds. The electronic control unit includes a speed signal processor which receives the signals produced by the wheel speed sensors and which determines the individual rotational speeds of the wheels and a vehicle reference speed therefrom. The electronic control unit further includes an evaluation and adjustment unit which detects any deviations between the vehicle reference speed and the individual rotational speeds, and which internally adjusts the individual rotational speeds to the vehicle reference speed if a deviation which is greater than a first predetermined amount but less than a second predetermined amount is detected during a fixed time period. However, if a deviation greater than the second predetermined amount is detected, no internal adjustment of the individual rotational speeds is made, but a warning light is turned on.
