Abstract
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.
Claims5
A vehicle behavior control device comprising:
- a controller;
- and
- an actuator configured to apply a control force to a wheel of a vehicle through position control by the controller, wherein
- the actuator includes a transmission member configured to transmit a reaction force generated by deformation to the wheel,
- the actuator is configured to apply the control force to the wheel by deforming the transmission member,
- an assumed reaction force is a reaction force to be generated in the transmission member due to at least one of acceleration or deceleration and steering of the vehicle when a position control amount of the actuator is zero, and
- the controller is configured to:
- calculate a request control force for the actuator;
- adjust the request control force in consideration of the assumed reaction force;
- and
- perform the position control on the actuator based on the adjusted request control force.
