2. SSPS (SPEED SENSING POWER STEERING)
OVERVIEW AND FUNCTIONS
1) OVERVIEW
In the conventional constant power assist steering system, the steerability gets lighter as
vehicle speed rises, and this may cause a dangerous situation. Where as having heavy
steerability in high speed driving makes it difficult to manipulate the steering wheel when
vehicle is in stop. This steering system solves this problem as the steerability is changed
according to the vehicle speed, which is called Speed Sensitive Power Steering (SSPS).
SSPS, by providing appropriate steerability to a driver according to the changes of vehicle
speed, gives steering stability. The power steering control unit adjusts the hydraulic pressure to
reaction plunger by controlling the pressure solenoid valve located in the gear box to optimize
the steerability. In other words, the steering wheel gets lighter by adjusting steerability in stop or
low speed and provides steering stability by adjusting steering wheel to become heavier in high
speed.
SSPS (Speed Sensitive
Power Steering)
- If the SSPS solenoid valve is defective, the power steering assembly should be replaced.
