1. A vehicle motion control apparatus, comprising:
a processor provided in a vehicle and configured to determine a riding position of a user, receive information related to a steering angle of the vehicle, and output a vehicle control signal with regard to turning motion performance according to at least one of a phase difference between a yaw rate and lateral acceleration or a lateral slip angle with respect to the riding position, based on the received steering angle; and
a controller configured to control the vehicle in accordance with the vehicle control signal,
wherein the processor is configured to:
determine a front wheel steering angle of the vehicle based on the received steering angle,
determine a steering ratio, based on a longitudinal speed of the vehicle and a longitudinal distance from the center of gravity of the vehicle to the riding position, and
determine a rear wheel steering angle of the vehicle, based on the front wheel steering angle and the steering ratio.
