VEHICLE MOTION CONTROL DEVICE AND VEHICLE MOTION CONTROL METHOD

The present invention provides a vehicle motion control device capable of reducing vibration generated in a running vehicle and suppressing the occurrence of an unstable behavior of the vehicle. A vehicle motion control device that controls a motion of a vehicle includes an operation management unit that generates traveling status information of the vehicle, a traveling track generation unit that generates a traveling track of the vehicle based on the traveling status information, and a travel control unit that controls driving, braking, and steering of the vehicle based on the traveling track. The traveling track generation unit includes a course planning unit that generates a target course based on the traveling status information and a speed planning unit that plans a target speed by calculating a longitudinal acceleration and a lateral acceleration whose composite acceleration has one peak when the vehicle travels on each curve in the target course.
