Abstract
An anti-skid brake control circuit arrangement for improving the steerability of a vehicle during braking on a roadway having a different coefficient of friction on opposite sides of the vehicle, and including a plurality of sensing devices for sensing the rotational behavior of the vehicle wheels. A plurality of control circuits associated with the sensing devices for evaluating the rotational behavior of the braked wheels and for obtaining +b, -b, and .lambda. control signals for controlling solenoid supply valves which regulate the brake pressure on the wheels so that the braking pressure is applied in pulses to a wheel running with a higher coefficient of friction. The control circuits and the solenoid supply valves are interconnected by at least two operating circuits which include timing circuits wherein the braking pressure on the wheel running with a higher coefficient of friction which has not yet been controlled is alternately held constant and then is increased in response to the control signals of the control circuit of the wheel running at a lower coefficient of friction.
