Classification: CPC B | IPC B

Claim 5:
6. A vehicle motion control device programmed to control a motion state of a vehicle during a vehicle transient motion in which an acceleration in a lateral direction is generated in the vehicle, wherein the vehicle motion control device is programmed to:
set a corrected longitudinal acceleration for correcting a basic longitudinal acceleration determined in accordance with a required driving force for traveling of the vehicle;
determine a target longitudinal acceleration from the basic longitudinal acceleration and the corrected longitudinal acceleration, and operate a travel actuator of the vehicle based on the target longitudinal acceleration, wherein a direction and a magnitude of the corrected longitudinal acceleration are determined from a viewpoint of suppressing a change in a posture of an occupant of the vehicle in a roll direction, and the direction of the corrected longitudinal acceleration is set to a positive direction along an advancing direction of the vehicle in at least a part of a section of the vehicle transient motion;
set the vehicle transient motion as a lane change in which a change in a lateral acceleration acting on the vehicle corresponds to a progress degree; and
set a direction of the corrected longitudinal acceleration to a positive direction along an acceleration direction of the vehicle in a section in which an absolute value of the lateral acceleration during the lane change decreases.
