4) S.S.P.S SYSTEM CONTROL
During parking and low speed driving
▶
During parking and driving in low speed, the control unit supplies approx. 1 A of electric current
to solenoid valve. Then, the spool located in PCV compresses the upper spring and elevates
upward, and the working pressure from oil pump (A port) is not able to flow to the reaction
plunger (C port). As a result, the pressing force from the reaction plunger disappears and the
steerability enhances.
The SSPS system, according to the vehicle
speed, enables to achieve proper steering
characteristics by controlling
pressure to reaction plunger located in input
shaft of power steering gear box. In other
words, the SSPS control unit enhances the
parking conveniences by controlling duty
type current control. It provides heavy
steerability with low current as the vehicle
speed increases. Also, it provides light
steerability with high current as the vehicle
speed decreases.
