VEHICLE BEHAVIOR CONTROL DEVICE AND VEHICLE BEHAVIOR CONTROL METHOD

The vehicle behavior control device includes a controller and an actuator that applies a control force to wheels of the vehicle through position control by the controller. The actuator is configured to apply a control force to the wheel by deforming the transmission member. The controller is configured to calculate a required control force for the actuator, adjust the required control force in consideration of the assumed reaction force, and perform position control of the actuator based on the adjusted required control force. Here, the assumed reaction force is a reaction force generated in the transmission member due to at least one of acceleration/deceleration and steering of the vehicle when the position control of the actuator is zero.
