1. A vehicle behavior control device, comprising:
an ith suspension mounted on an ith wheel of four wheels of a vehicle (where i=1 to 3);
a fourth suspension mounted on a fourth wheel other than the ith wheel; and
a controller, wherein
the ith suspension includes an ith actuator configured to apply a control force in an up-down direction to the ith wheel,
the controller is configured to
calculate a required value of a behavior parameter representing behavior of the vehicle,
convert the required value of the behavior parameter to an ith required control force for the ith actuator, and
control the behavior of the vehicle by controlling the ith actuator based on the ith required control force, and
the controller is configured to, when a kth required control force (where k is any of 1 to 3) is greater than a kth output range according to an output capability of a kth actuator, perform a required control force reduction process of reducing all of a first required control force, a second required control force, and a third required control force, and control the ith actuator based on the ith required control force after the required control force reduction process.
