<p>PURPOSE:To enhance stability and safety in turning of a running car by changing the deviational angle of rear wheels, being operated by an actuator to drive the trunk rod and thereby making constant the cornering performance when the car runs turning. CONSTITUTION:Signals given from a front-wheel load sensor 1 and a rear-wheel load sensor 2 are added with a signal from a sideways acceleration sensor 3, and the sum obtained is entered into a control map 53. This control map 53 is stored in memory so that its ROM outputs the rear-wheel steering angle in correspondence with the specified front-axle load ratio and the sideways load applied to the car body, and the ROM is so arranged that the optimum steering angle according to signals from operational circuits 51 and 52 can be read. A solenoid-operated control valve 6 is driven in accordance with the output from the control map 53, and an actuator 7 is driven for a certain specified stroke to give the rear wheels 8 a specific steering angle theta.</p> |
