Steering: Description and Operation

GENERAL





The Electronic Power Steering (EPS) system uses the same components at that of conventional power steering system. In addition, it has a solenoid valve on power steering gear box, and a control unit underneath the audio of the center facie. To control the oil flow of steering gear box, a solenoid is provided and it functions by the current from control module which receives signal from Vehicle Speed Sensor (VSS).
EPS performs the conventional power steering function in case a fail has occurred in the system.
EPS electronically controls the current to the solenoid of by-pass valve by input sensor's signal to control the hydraulic amount in cylinder chamber thereby varying the steering effort versus the hydraulic pressure according to vehicle speed.
