Motor Position Sensor of Actuating Unit
The motor position sensor of the actuating unit is located on the rear side of the electric motor of the active front steering actuating unit. The motor position sensor consists of a sensor chip and a magnet. The sensor chip records the position of the electric motor according to the magneto-resistive principle. The information on the rotor position is sent to the active front steering control unit via a direct line in pulse width modulated form. See Fig 1.
