General Description
EPS (Electronic Power Steering ) SystemGENERAL
The electronic power steering (EPS) system includes the same components of conventional power steering system.
EPS performs the conventional power steering function in case a failure has occurred in the system. EPS electronically controls the current to the solenoid of the by-pass valve by inputting sensor's signals to control the hydraulic amount in cylinder chamber and thereby varying the steering effort by the hydraulic pressure according to vehicle speed.
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 signals from VSS (Vehicle Speed Sensor).
