Abstract
A vehicle motion control device is configured to determine whether the lane in which the vehicle is traveling is straight or curved. If the road is curved, a target yaw rate is set such that the yaw rate of the vehicle to the target position is averaged. If the road is straight, the target yaw rate is set such that the response delay does not exceed a target value. Therefore, wavering of the vehicle with respect to the lane is suppressed, and the vehicle is controlled to move smoothly when the road is curved and briskly when the road is straight. When the road switches between a curved road and a straight road, the target yaw rate is gradually changed between a target yaw rate calculated for a curved road and a target yaw rate calculated for a straight road.
