1. OVERVIEW

The speed-sensitive power-assisted steering system can automatically adjust the boosts according to 

the speed changes, automatically induct the high-speed or low-speed status, and relatively adjust the 

reasonable steering boosts, enhance the operation precision, reduce the driving pressure of drivers. No 

matter for steering, parking or reversing, it becomes much easier. The adjustable safety steering column 

attached possesses the functions of electrically adjusting height and transverse position, has brought 

much more abundant and comfortable spaces for legs, and has provided the great convenience to get in 

or out the car. 

The Speed Sensitive Power Steering (SSPS) unit controls the SSPS solenoid vale in steering gear box 

to get proper power steering force.
