ABSTRACT:
An anti-skid brake control device has a control circuit 6 to which signals from a steering angle sensor 14, a yaw detector 7 and respective wheel velocity sensors 3a.about.3d of a motor vehicle are inputted, an oil pressure actuator 5 controls of the pressure of the braking fluid for respective wheel cylinders 2a.about.2d based upon target slip rates Sfrt. Sflt, Srrt and Srlt and measured slip rates Sfr, Sfl, Srr and Srl for the respective wheels calculated in the control circuit 6. The target slip rates for the respective wheels, which are principally determined dependent upon the deviation .beta. between compensated target yaw angular acceleration .omega.R and measured yaw angular acceleration .omega., are set independently and are modified dependent upon the motor vehicle body velocity, whereby the braking forces for the respective wheels are independently controlled . In this way, it is possible to suppress generated yaw moment and to improve stability of the motor vehicle, while also safely reducing the braking distance.
