A stability control system for controlling an running attitude of a vehicle by applying braking force selectively and independently to the wheels so as to direct the vehicle toward a target direction applies braking force independently to a front wheel at the inner side of the cornering path to impart a yaw moment to the vehicle so that the inner front wheel yields a wheel slip ratio less than an upper limit of understeer wheel slip ratio which is set to be smaller than a wheel slip ratio at which each wheel provides the maximum force in the running direction.

[ What is claimed is:] [1.] A driving stability control system for a vehicle equipped with a braking system capable of applying braking force to wheels of the vehicle for controlling said braking system to apply braking force selectively and independently to at least one of the wheels so as to direct the vehicle toward a target direction, said stability control system comprising:wheel speed detecting means for detecting a wheel speed of each said wheel;lateral acceleration detecting means for detecting lateral acceleration acting on the vehicle;yaw rate detecting means for detecting a yaw rate of the vehicle;steering angle detecting means for detecting a steering angle of a steering wheel; andcontrol means for calculating an actual slip angle and a target slip angle of the vehicle based on said wheel speed, said lateral acceleration, said yaw rate and said steering angle, judging whether the vehicle tends to understeer on the basis of a deviation of said actual slip angle from said target slip angle, and controlling, when the vehicle is judged to tend to understeer, the braking system to apply braking force to a front wheel on an inner trace of a cornering path to impart a yaw moment to the vehicle in a direction in which the vehicle is restrained from understeering so that said front wheel yields a slip ratio less than a specified upper limit wheel slip ratio which is set to be smaller than a slip ratio at which said front wheel provides a maximum longitudinal component force.
