VEHICLE BEHAVIOR CONTROL DEVICE

A vehicle behavior control device includes: an ith suspension mounted on an ith wheel of a vehicle (where i=1 to 3); a fourth suspension mounted on a fourth wheel; and a controller. The ith suspension includes an ith actuator. The controller converts a required value of a behavior parameter to an ith required control force for the ith actuator. When a kth required control force (k is any of 1 to 3) is greater than a kth output range according to an output capability of a kth actuator, the controller performs a required control force reduction process of reducing all of first to third required control forces, and controls the ith actuator based on the ith required control force after the required control force reduction process.
