Abstract
A vehicle motion control system for a vehicle for maintaining stability of a vehicle when the vehicle is in motion includes braking device for applying a braking force to each wheel of the vehicle. The system includes a lateral acceleration sensor for sensing a lateral acceleration of the vehicle and a yaw rate sensor for sensing a yaw rate of the vehicle. A vehicle slip angular velocity is calculated on the basis of output signals of the lateral acceleration sensor and the yaw rate sensor and then a vehicle motion condition is determined on the basis of the vehicle slip angular velocity. The braking device is actuated to apply a braking force to at least one of the wheels on the basis of the vehicle motion condition and irrespective of depression of the brake pedal in order to maintain the stability of the vehicle in motion. An abnormal condition of at least one of the lateral acceleration sensor and the yaw rate sensor is determined on the basis of the vehicle slip angular velocity.
