EPS unit
The EPS unit consists of the following components:
- EPS control unit
- Servomotor with integrated rotor position sensor
The EPS control unit is part of the electromechanical power steering. The EPS control unit is connected to the vehicle electrical system with 2 plug connections. The steering-torque sensor is connected via another plug connection to the EPS control unit. A number of characteristic curves for power assistance, active steering wheel return as well as damping characteristics are stored in the EPS control unit. The values calculated from the input variables added to each characteristic curve result in the necessary steering servo.
Depending on equipment specification, the EPS unit may also be supplied via terminal 30. The power distribution box in the junction box supplies the EPS control unit with terminal 15N.
