ABSTRACT:
If a driver's sudden operation of a steering handle to avoid an obstacle is detected based on outputs from a steering speed sensor (S.sub.1), a steering torque sensor (S.sub.2) and/or a steering torque variation amount sensor (S.sub.7), a master cylinder produces a braking hydraulic pressure by a command from an electronic control unit without depression of brake pedal by a driver. A hydraulic pressure control device (4) transmits the braking hydraulic pressure to brake calipers of inner wheels during turning of the vehicle to brake the inner wheels. This causes a yaw moment to be generated so as to turn the direction of advancement of the vehicle to an inward in a turning direction. Thus, the steering operation can be assisted by such yaw moment to avoid the obstacle.
