In a drive control device for a motor vehicle, which works on the principle of slowing down a vehicle wheel with a tendency to spin by automatic activation of its wheel brake to such an extent that its wheel slip remains within a range of values compatible both with good drive acceleration and with good driving stability, the brake pressure, in drive control phases, being supplied from a gas piston accumulator, which can be connected by way of a reversing valve to the brake circuit of the driven vehicle wheels, and the brake pressure to the vehicle wheels subjected to control being controlled by way of brake pressure control valves individually assigned to those wheels, with which valves the reversing valve is connected in series, a solenoid arrangement is provided which, on conclusion of the last pressure reduction phase of a control cycle, provides a communicating connection between a brake line section connecting the reversing valve to the brake pressure control valves and the brake fluid reservoir of the brake system, so that brake fluid previously under high pressure in this brake line section can expand directly to the brake fluid reservoir. This prevents brake fluid which originates from the accumulator and is used in drive control phases for the admission of pressure to the wheel brake subject to control, from ... into which fluid pressurised gas from the pressure chamber of the ...
