UNDERSTEER Behavior Suppression

When the vehicle starts to drift outward during cornering, the VDCCM causes the rear inner wheel to be braked. As a result, a yaw moment is generated in a direction that counteracts the yaw moment resulting from under steer so that the vehicle's behavior is stabilized.
