<p>PURPOSE:To improve responsiveness, stability, and steering performance and obtain the simple constitution by controlling the damping force controller of a shock absorbing device by the torque instruction signal of a steering wheel. CONSTITUTION:The steering power of a steering wheel 2 is inputted into a power steering control circuit 71 and a ground clearance control circuit 72 from a torque sensor 5. Similarly, the steering angle is inputted into the control circuit 71 from a steering angle sensor 6, and the car speed is inputted into the control circuit 72 from a car speed sensor 11. When the car speed is over a prescribed value, and the torque value is over a prescribed value, and the steering angle is over a prescribed value, the ground clearance control circuit 72 reads the damping force corresponding to the torque value from a memory, and the car speed correction for the damping force is executed. The electric current control calculation is carried out according to the corrected damping force, and a motor 13 for actuator is driven through an actuator motor driving circuit, and the damping force of a shock absorber 12 is varied. With such constitution, responsiveness can be improved.</p> |
