Behavior control system for vehicle
First Claim
1. A vehicle behavior control system comprising a controller that obtains a normal vehicle state value based on an operation amount of a vehicle operating member performed by a vehicle operator, and controls a vehicle behavior based on an actual vehicle state value and the normal vehicle state value, wherein the controller estimates an amount of correction with respect to the vehicle operating member by the vehicle operator, and obtains the normal vehicle state value based on the estimated amount of correction and an actual operation amount.

Abstract
In a vehicle behavior control system, a target braking force applied to each wheel of the vehicle is obtained based on a master cylinder pressure so as to be proportional to a vertical load of each wheel. When it is determined that a braking force is applied to the vehicle running on a road with uneven friction coefficient, an excess yaw moment caused by the difference between the target braking force and an actual braking force is calculated. A steering angle is corrected with a correcting steering angle estimated based on the excess yaw moment. A yaw rate difference is calculated as a difference between a normal yaw rate and an actual yaw rate of the vehicle based on the steering angle that has been corrected. It is determined whether the vehicle behavior is deteriorated based on the yaw rate difference. The vehicle behavior is then controlled to reduce the yaw rate difference.
