Abstract
There is provided a vehicle motion control system which carries out acceleration and deceleration of a vehicle which satisfies driving feeling of a driver even in the state where a lateral motion of the vehicle is not involved. The vehicle motion control system includes a curve shape acquisition sectionfor acquiring a curve shape ahead of an own vehicle, an own vehicle position acquisition sectionfor acquiring a position of the own vehicle, and a vehicle motion control calculation sectionfor calculating a command value of a longitudinal acceleration generated for the vehicle based on the curve shape and the position of the own vehicle. The vehicle motion control calculation sectioncalculates a plurality of negative longitudinal acceleration command values during travel of the own vehicle from before a curve to a point where a curve curvature becomes constant or maximum after the vehicle enters into the curve. The longitudinal acceleration command values are changed based on at least one of: an estimate of the maximum lateral acceleration which is presumably generated during traveling a curve ahead of the own vehicle; a grade of the road ahead of the own vehicle, pedal operation by the driver, and a turning direction.
