Patent ID: 8170826

Claim:
A method for the calibration of a position determination system of a rear axle steering actuator for a motor vehicle which has an actuator element which can be driven by a rotary movement of a rotor to a translation movement and whose geometrical center position is determined by a reference measurement, the method including: providing the position determination system with a linear sensor and a rotary sensor; generating a piece of calibration information during the calibration which includes a piece of zero point information of the linear sensor and a piece of sector information of the rotary sensor; wherein the measurement range of the rotary sensor is divided into at least two sectors and the sector information identifies that sector in which the angular position (M i ) of the rotor detected by the rotary sensor lies when the actuator element is arranged in its geometrical center position; and storing both the piece of zero point information and the piece of sector information which define the calibration information in the linear sensor.
