A velocity-sensitive type of variable-assist power steering introduced by Honda provides full steering assistance at low speeds, gradual reduction in assistance with increasing vehicle speed, and a normal unassisted "road feel" at highway speeds. Unlike a Citroen system which sensed the amount of steering wheel rotation and provided an artificial feedback, the Honda system provides steering assistance proportional to the torque applied to the steering wheel for "natural road feel" . The power source is a gear-type hydraulic pump, belt driven by the engine. Pump noise was reduced to an acceptable level by development of the port position, gear form, and flexibility of the feed hose. A flow control valve prevents the pump from producing too much flow at high engine rpm. A relief valve was included to prevent excessive pressure when the steering is held in the full lock position.
