DESCRIPTION & OPERATION
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 facia. 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 VSS (Vehicle Speed Sensor).
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.
The EPSCM is installed underneath the audio inside the center facia.
