  • Patent number: 11938951
    Abstract: A vehicle motion control method controls a motion state of a vehicle during a vehicle transient motion in which an acceleration in a lateral direction is generated in the vehicle. The vehicle motion control method includes: setting a corrected longitudinal acceleration for correcting a basic longitudinal acceleration determined in accordance with a required driving force for traveling of the vehicle; and determining a target longitudinal acceleration from the basic longitudinal acceleration and the corrected longitudinal acceleration, and operating a traveling actuator of the vehicle based on the target longitudinal acceleration. 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.
