EPS unit
The EPS unit consists of the following components:
- EPS control unit
- Electric motor with motor position sensor
The EPS control unit is part of the electromechanical power steering. The EPS control unit is connected with 2 plug connections to the vehicle power system. The steering momentum sensor is connected via another plug connection at 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 power assistance.
The fuse box in the engine compartment supplies the servo unit with terminal 30.
