摘要： A four wheel steering system for a motor vehicle with steerable front and rear road wheels, a steering angle sensor for detecting a front wheel steering angle through which the front road wheels are steered, a vehicle speed sensor for detecting a vehicle speed of the motor vehicle, a rear wheel steering mechanism for steering the rear wheels, and a controller for controlling the rear wheel steering mechanism to steer the rear road wheels based on the detected front wheel steering angle and the detected vehicle speed when the front road wheels are steering. The controller controls the rear wheel steering mechanism to steer the rear road wheels in a direction which is opposite to the front road wheels if the detected vehicle speed is relatively low, and also controls the rear wheel steering mechanism to steer the rear road wheels in a direction which is the same as the front road wheels if the detected vehicle speed is relatively high. Furthermore, the controller controls the rear wheel steering mechanism to increase a rear wheel steering angle which through the rear road wheels are steered as the front wheel steering angle increases if a change in the front wheel steering angle is relatively small, and controls the rear wheel steering mechanism to reduce an increase in the rear wheel steering angle if a change in the front wheel steering angle is relatively large.

摘要： In a brake control system for yaw control in a vehicle, the conditions for starting a brake operation are that the absolute value of a deviation between a target yaw rate determined in a target yaw rate determining device and an actual yaw rate detected by a yaw rate detecting device is equal to or greater than a preset deviation value and that the absolute yaw rate is equal to or greater than a preset value. The wheel brake for an outer wheel, during turning of the vehicle, is operated by the yaw control system based on the deviation between both the yaw rates. However, brake control does not occur when both of the yaw rates are the same in direction and are large. Thus, yaw control is conducted immediately when necessary, but the conduction of unnecessary yaw control is avoided, thereby reducing the frequency of the brake operation.
