VEHICLE ATTITUDE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To stabilize a vehicle behavior by feedforward controlling a steering angle in correspondence to a difference of a braking force between an inner turning wheel and an outer turning wheel for stabilizing the vehicle behavior by controlling the braking force of right and left wheels under under-steer condition or over-steer condition. SOLUTION: A steering angle varies in correspondence to movements of an actuator 2 for steering driven in correspondence to operations of an operation member 1. A difference of a braking force between an inner turning wheel 4 and an outer turning wheel 4 generates yaw moment to stabilize a vehicle. A steering angle setting value, corresponding to a target behavior index value corresponding to the difference of the braking force and a manipulated variable of the operation member 1, is added to a steering angle correction value corresponding to a deviation between the target behavior index value and the obtained behavior index value to obtain a target steering angle. The actuator 2 for steering is controlled so that the steering angle corresponds to the target steering angle.
