Abstract:
1. A motion control device for a vehicle having a braking means for applying a brake torque to a wheel of the vehicle and maintaining a traveling stability of the vehicle by controlling the braking means, the motion control for the vehicle, comprising: a steering angular velocity obtaining means for obtaining a steering angular velocity of the vehicle; a maximum steering angular velocity calculating means for calculating, on the basis of the steering angular velocity, a maximum steering angular velocity over a period of time corresponding to a duration of 1) a J-turn steering operation in which a steering wheel is abruptly operated in one direction, or 2) a lane-change steering operation in which the steering wheel operation is sequentially performed in the other direction after the steering wheel operation is abruptly performed in one direction; a determining means for determining a reference turning state quantity on the basis of the maximum steering angular velocity, wherein the determining means determines the reference turning state quantity in a manner where the greater the maximum steering angular velocity is, the smaller value the reference turning state quantity is determined to be, alternatively, the smaller the maximum steering angular velocity is, the greater value the reference turning state quantity is determined to be; an actual turning state quantity obtaining means for obtaining an actual turning state quantity of the vehicle; and a control means for controlling the brake torque on the basis of the reference turning state quantity and the actual turning state quantity, wherein the control means controls the braking means when the actual turning state quantity exceeds the reference turning state quantity in order to start applying the brake torque to the wheel.
