1. A brake force control device for vehicles with a back-control means reducing the brake pressure of the pressure control medium upon exceeding a maximum force acting at a wheel and with disengagement of the back-control means with a re-decreasing force after re-passing through the maximum value, characterized by further means for controlling the engagement and disengagement of said back-control means by signals including signal producing means for forming said signals, taking into consideration the hysteresis effect of the control operation, by the signs of the derivatives with respect to time of the force acting on the wheel and of the brake pressure, and characterized in that the back-control means causing a reduction of the brake pressure is initiated with an increasing brake pressure and a decreasing wheel force only if prior thereto both wheel force and brake pressure increased, and is turned-off with a decreasing brake pressure and a decreasing wheel force only if prior thereto the wheel force increased with a decreasing brake pressure.
