Speed Sensitive Power Steering System: Notes

The Speed Sensitive Power Steering (SSPS) system varies driver effort required to steer as vehicle speed changes. At low speeds, system provides maximum power assist for easy turning and parking maneuvers. At higher speeds, steering power is reduced to provide driver with firmer steering and directional stability. The SSPS system accomplishes this by reducing amount of power steering fluid flow from power steering pump to pwoer steering gear ad vehicle speed increases. When vehicle is stationary, SSPS system provides maximum fluid flow to steering gear. As vehicle speed increases, fluid flow to steering gear is decreased.
