Calibration method for a position determination of a rear axle steering actuator

摘要

The present invention relates to a method for the calibration of a position determination system of a rear axle steering actuator for a motor vehicle. The rear axle steering actuator 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 means of a reference measurement. The position determination system includes a linear sensor and a rotary sensor. During the calibration of the position determination system, a piece of calibration information is generated which includes a piece of zero point information of the linear sensor and a piece of sector information. The measurement range of the rotary sensor is divided into at least two sectors. The sector information identifies that angle at which the angular position of the rotor defined by the rotary sensor lies when the actuator element is arranged in its geometrical center position. The calibration information is stored in the linear sensor.
