Abstract:
A vehicle behavior control apparatus having target yaw rate establishing means for establishing a target yaw rate as a control target of said vehicle behavior control apparatus, said target yaw rate establishing means comprising:vehicle mass estimating means for estimating a vehicle mass based on a vehicle acceleration or deceleration; mass distribution calculating means for calculating a mass distribution between front and rear axles based on said vehicle mass; front and rear axles to gravity center distance calculating means for calculating distances between front and rear axles and a center of gravity; front wheel steering angle calculating means for calculating a steering angle of a front wheel based on a steering wheel rotation angle; first stability factor calculating means for calculating a stability factor on steering left based on at least one of said vehicle mass, said vehicle mass distribution, said distances between front and rear axles and center of gravity and said steering angle of said front wheel; second stability factor calculating means for calculating a stability factor on steering right based on at least one of said vehicle mass, said vehicle mass distribution, said distances between front and rear axles and center of gravity and said steering angle of said front wheel; and target yaw rate calculating means for calculating said target yaw rate based on said first stability factor when turning left and for calculating said target yaw rate based on said second stability factor when turning right.
