Abstract
In a vehicle attitude control apparatus, a steering actuator is controlled so that a steering angle matches a target steering angle. In an understeer condition; the braking force on the inside wheels is increased and drive power applied to the outside wheels is larger than applied to inside wheels. In an oversteer condition, the braking force on the outside wheels is increased and drive power applied to the inside wheels is larger than applied to outside wheels. The steering actuator is controlled so that a behavior index value corresponding to the change in the vehicle'behavior, that occurs based on the change in the steering angle, matches a target behavior index value that reflects the amount of operation of an operation member. A vehicle yaw moment and an amount of control of the steering actuator vary due to steer conditions, wheel lateral slip angle and brake force control.
