Function
General
The electric power steering control unit is the central control unit for the steering functions.
Function
The electric power steering control unit engages in the following functions:
Electronic Stability Program (ESP®)
Active Park Assist
In order to carry out these functions, the electrical power steering control unit primarily processes the following input factors:
Steer Assist torque request and wheel speeds
Engine status, drivetrain operational and engine speed
Steering wheel angle and steering wheel velocity
Current status and requested toothed rack position of parking system control unit
The electric power steering control unit processes these input factors and primarily transmits the following actuations:
Warning message in multifunction display of instrument cluster
Steering torque, steering wheel velocity and steer assist status to the ESP® control unit
Electrical power steering control unit, status
Toothed rack position
The electrical power steering control unit is attached to the rack-and-pinion steering together with the electric power steering actuator motor.
