Abstract
An anti-skid control system of a vehicle comprising a yaw motion sensing device of the vehicle, a device for calculating target slip rates of the wheels according to the yaw motion, a wheel speed detecting device for detecting actual speeds of the wheels, a control device for generating a control signals based on the target slip rates and the actual speeds of the wheels, a control valve for controlling braking oil pressure according to the control signals, a first failure detecting device for detecting an abnormality relating to the yaw motion sensing device, a second failure detecting device for detecting an abnormality relating to the control valve, and a failsafe control device for keeping the target slip rates from the calculating device constant and when the abnormality relating to the yaw motion sensing device is detected and for bringing the control valve into a non-operating state when the abnormality relating to the control valve is detected.
