Abstract
A brake force control system for vehicles, especially an electronic brake force control system for motor vehicles and rail vehicles, with a back-control (1) reduction control (1) of the brake pressure of the pressure control medium causing a reduction of the brake pressure when a maximum wheel circumferential force acting at the wheel is exceeded; the back-control being disengaged when the wheel circumferential force again increases after re-exceeding the maximum value whereby the engagement and disengagement of the back-control of the brake pressure is controlled by signals which are formed, taking into consideration the hysteresis effect of the control operation, by the signs of the derivatives with respect to time of the circumferential force and of the brake pressure.
