PROBLEM TO BE SOLVED: To provide a motion control device of a vehicle capable of improving drivability, stability, and riding comfort.SOLUTION: A motion control device of a vehicle includes: control means 405 that independently controls driving force of respective wheels of a vehicle 0; acceleration and deceleration command arithmetic means 402 that calculates an acceleration and deceleration command value on the basis of a lateral acceleration; first yaw moment command arithmetic means 403 that calculates a first vehicle yaw moment command value on the basis of the lateral acceleration; second yaw moment command arithmetic means 404 that calculates a second yaw moment command value on the basis of skidding information. The motion control device of the vehicle 0 has: a first mode in which substantially identical driving force is induced in left and right wheels out of four wheels on the basis of the acceleration/deceleration command value to control acceleration and deceleration; a second mode in which different driving force is induced in the left and right wheels out of the four wheels on the basis of the first yaw moment command value to control yaw moment; and a third mode in which different driving force is induced in the left and right wheels out of the four wheels on the basis of the second yaw moment command value to control the yaw moment.SELECTED DRAWING: Figure 24
