Abstract
It is known that an output valve providing a pressure decrease in a wheel brake cylinder can be controlled by a pulse train which is variable in response to the acceleration or deceleration of the associated wheel. A disadvantage of such an arrangement is that a wheel at standstill will not be able--under certain circumstances--to accelerate again during a control cycle. Additionally, the wheel brake cylinder pressure may have been decreased to such an extent that the wheel will neither continue to decelerate, or accelerate sufficiently. According to the present invention the control behavior is improved in these critical cases by generating pulses proportional to wheel acceleration and to transmit an opening signal to the outlet valve upon cessation of the accelerating pulses. The opening signal is immediately switched off as soon as the acceleration pulses occur again.
