An apparatus for propulsion control in a motor vehicle with an anti-locking system is proposed, in which the supply and outflow of pressure medium is controllable via electromagnetically actuatable valves and which is characterized in that means are provided with which the return flow line can be exposed to pressure. It is the purpose of the apparatus to expand an anti-locking system to include a drive slippage regulating function, and this expansion is problem-free and cost-favorable. The proposed apparatus furthermore assures that a brake pedal actuation has priority. It is also proposed in the case of excessive slippage of both driven wheels to reduce the engine output. This is attained with a controllable drag member disposed between the driving pedal (or linkage) and the throttle valve, the control of the drag member being effected by means of the auxiliary pressure in the return flow line and via an electromagnetically controllable three-port, two-position valve for a hydraulic AND member.

A brake apparatus for a motor vehicle having anti-skid regulation and regulation of the start-up slippage, including a brake pressure generator for supplying a pressure medium in a main line, a pressure source containing a pump, valve means actuatable by a control circuit in accordance with wheel movement behavior for blocking the supply of said pressure medium and for diverting said pressure medium into a return-flow line, a further valve for connecting said pressure source to wheel brakes of said motor vehicle, said control circuit actuating said valve means for the purpose of pressure regulation, said further valve being incorporated into said return-flow line for the purpose of feeding the pressure of said pressure source into said return-flow line and via said valve means into a wheel brake cylinder of a wheel exhibiting a start-up slippage.
