Identification of overload current

The EPS identifies overload current situations using an internal monitoring routine. The steering angle, steering wheel angular velocity, driving speed and steering torque applied by the driver are all used to calculate the required steering power. If a permitted load limit is exceeded, the steering servo is reduced or switched off completely in order to protect the power electronics.

Overload current situations can be caused by the following traffic situations:

• The vehicle is very close to the curb and is pushed away by a steering action.
