MOTION CONTROL DEVICE OF VEHICLE

摘要

A motion control device 10 for a vehicle exerts braking force only on the rear wheel at the inner side of the turning direction for generating a yawing moment on the vehicle only in the turning direction of the vehicle when an absolute value of an actual lateral acceleration Gy is not more than a value Gyth, i.e., when there is a small possibility of the occurrence of an excessive roll angle on the vehicle body, in case where the turning state of the vehicle is the understeer state. On the other hand, it exerts braking force not only on the rear wheel at the inner side of the turning direction, but also on the front and rear wheels at the outer side of the turning direction for generating a yawing moment in the direction opposite to the turning direction too, when the absolute value of the actual lateral acceleration Gy exceeds the value Gyth, i.e., when there is a great possibility of the occurrence of the excessive roll angle on the vehicle body, in case where the turning state of the vehicle is the understeer state.
