Abstract
Disclosed is a vehicle motion control system that can control a vehicle without making a driver feel uncomfortable. The vehicle motion control system includes a control command value calculation unit configured to calculate a control command value for controlling the longitudinal acceleration of a vehicle; a longitudinal acceleration estimating unit configured to estimate the longitudinal acceleration of the vehicle induced by a driver's brake operation; a longitudinal jark estimating unit configured to estimate the longitudinal jark of the vehicle by differentiating the longitudinal acceleration with respect to time; a deviation determination unit configured to determine a deviation between vehicle's motion induced by the driver's brake operation and vehicle's motion induced by a control command using the longitudinal jark and the control command value; and a control command value correction unit configured to correct the control command in accordance with a deviation determination result of the deviation determination unit.
