ABSTRACT:
A failure detecting apparatus for an anti-skid brake control system of a motor vehicle comprises a main microcomputer for generating a hydraulic pressure control signal for controlling an actuator adapted to generate braking efforts to be applied to wheels of the motor vehicle, an auxiliary microcomputer for detecting occurrence of a failure in the main microcomputer on the basis of the hydraulic pressure control signal, a test signal generating means implemented in the main microcomputer or the auxiliary microcomputer to generate a test signal, an anti-skid brake control arithmetic means incorporated in the main microcomputer to generate a hydraulic pressure control signal on the basis of either a wheel speed signal or the test signal, and a hydraulic pressure control signal monitoring means implemented in the auxiliary microcomputer to monitor the hydraulic pressure control signal generated in response to the test signal, to thereby check the validity of the hydraulic pressure control signal. An anti-skid brake control system equipped with a self-diagnosis function can be implemented inexpensively.
