Abstract
An antiskid control device is for use with the brake assembly of a motor vehicle. It includes a program for detecting any malfunction of wheel speed sensors of the non-driven wheels. The program is adapted to judge when the non-driven wheel sensors are out of order and to give a signal notifying the abnormality of the sensors, if the wheel speed values detected by the non-driven wheels are kept out of a predetermined range for a predetermined period while the wheel speeds detected by the driven wheel speed sensors are above a predetermined point. Thus, a possible malfunction of the antilock device itself resulting from wrong information transmitted from the troubled non-driven wheel sensors will be identified and prevented.
