ABSTRACT:
The present invention is directed to a vehicle motion control system for maintaining vehicle stability by controlling the braking force applied to at least one wheel of a vehicle. A vehicle condition monitor monitors a condition of the vehicle in motion. A steering control unit actuates a braking unit to apply the braking force to at least one wheel on the basis of the output of the monitor and irrespective of depression of a brake pedal. An anti-skid control unit actuates the braking unit to control the braking force applied to at least one wheel in response to a rotational condition thereof during braking. A subordinate control unit actuates the braking unit to adjust the braking force control performed by the anti-skid control unit, in accordance with a predetermined relationship between the anti-skid control unit and the subordinate control unit. And, a priority control unit is adapted to give priority the anti-skid control unit over the steering control unit, and give priority the steering control unit over the subordinate control unit, when the condition for starting the braking force control performed by both of the anti-skid control unit and the steering control unit is fulfilled with respect to at least one wheel.
