PURPOSE:To properly control the actual motion characteristic not only in a kind of a road but also in a relation to a driving characteristic of a driver, in a device wherein the present position of a vehicle on the ground is detected to control a motion characteristic of the vehicle based on running information corresponding to this detection. CONSTITUTION:The present position of a vehicle is read by an S1 from a navigation computer, a reference value (value for preventing vehicle from falling into unstable condition) of a vehicle motion condition corresponding to this position is read by an S2 from a data base, car body longitudinal acceleration GX, cross acceleration GY, yaw rate gamma and a car speed V are detected by an S3 as a value of receiving an influence of a driving characteristic of a driver by each sensor, and the respective detection values of' these GX, GY, gamma and V and deviations DELTAGX, DELTAGY, DELTAgamma and DELTAV from each reference value are calculated by an S4. Rear wheel steering angle control and steering torque assist amount control are performed so as to improve running stability of the vehicle in accordance with increasing this calculating result. |
