ABSTRACT:
Steering stability of a vehicle under a traveling state such as cornering is enhanced by controlling a state of the vehicle based on cornering powers of right and left wheels. A detecting unit1detects action force containing longitudinal force Fx, lateral force Fy and vertical force Fz which act on each wheel. A specifying unit2specifies a friction coefficient between the wheels and road surface. An estimating unit6estimates cornering power ka of each wheel based on the action force and the friction coefficient. A processing unit7determines control values so that the representative value ka_ave of the cornering powers concerning the right and left wheels is larger than the present value of the representative value ka_ave of the cornering powers concerning the right and left wheels. Controlling units8to10control the state of the vehicle based on the control values thus determined.
