CONTROL DIAGRAM
System Description
- The EPS system controls the power steering solenoid valve
through the power steering control unit. - The valve driving voltage to control the power steering solenoid
valve varies according to the vehicle speed.
OPERATION PRINCIPLE
During Parking (When Turning The Steering Wheel To The Right)
- Power steering solenoid valve is closed while a vehicle is stopped.
- Pinion "1R", "2R" and "3R" are closed depending on steering torque of steering wheel.
- Oil pressure "P" in the gear housing assembly is the sum of oil
pressures occurring in "2R" and "3R". This
results in a light steering force because of high pressure.
During High-speed Operation
- Power steering solenoid valve is opened during high-speed operation.
- Pinion "1R", "2R" and "3R" are closed depending on steering torque of steering wheel.
- Oil pressure "2R" does not occur because the power steering solenoid valve is on full throttle.
- Oil pressure "P" in the gear housing assembly includes only oil pressure
occurring in "3R" and results in a
heavy steering force.
