ABSTRACT:
The present invention is directed to a vehicle motion control apparatus, which includes a steering factor detection unit for detecting at least one of steering factors including a steering torque and steering effort applied to a steering system, an aligning torque estimation unit for estimating an aligning torque produced on at least a wheel of the vehicle on the basis of the steering factor, a vehicle state variable detection unit for detecting a state variable of the vehicle, a wheel factor estimation unit for estimating at least one of wheel factors including a side force and slip angle applied to the wheel on the basis of the vehicle state variable, and a grip factor estimation unit for estimating a grip factor of at least a tire of the wheel, in accordance with the estimated alignment torque and the estimated wheel factor. The apparatus further includes a first control unit for performing a closed loop control on the basis of the grip factor, and a second control unit for performing a closed loop control on the basis of a deviation between a detected actual vehicle behavior and a desired vehicle behavior set on the basis of the vehicle state variable.
