ABSTRACT:
An antiskid control device including a wheel speed detecting member, an antiskid processor member for performing arithmetic operation on the basis of a wheel speed signal from the wheel speed detecting member and issuing to a hydraulic circuit, first and second commands of reducing and increasing a braking pressure upon detection of trends of wheels towards locking and towards recovery from locking, respectively, a solenoid driving member for driving a solenoid for a pressure control valve of the hydraulic circuit in accordance with the first and second commands and a decision member for deciding that the wheel speed detecting member is malfunctioning when a state that the arithmetic and locking state detecting member does not issue the first command to the hydraulic circuit during a first predetermined time period has not been detected at all during a second predetermined time period.
