Abstract
An adjustment system and method is provided for determining a set position of a motor-driven adjustment part of a motor vehicle by a Hall sensor, which is arranged in a rotated magnetic field. The drive of the adjustment part is activated for a specified number of approaches of the adjustment part toward an end position. A counter is changed by a counting value upon each approach of the adjustment part toward the end position. A standardization drive to the end position is carried out when the specified number of approaches is reached, and each deactivation and/or activation of the Hall sensor is detected and the counter state of the counter is changed according to the number of deactivation and activation cycles.

A method for determining a set position of a motor-driven adjustment part of a motor vehicle, the method comprising:
- arranging a Hall sensor in a rotated magnetic field, a drive of the adjustment part being activated for a specified number of approaches of the adjustment part toward an end position;
- changing a counter by a count value upon each approach of the adjustment part toward the end position;
- performing a standardization run to the end position when the specified number of approaches is reached;
- detecting each deactivation and/or activation of the Hall sensor;
- and
- changing the counter state of the counter according to the number of deactivation and activation cycles.
An adjustment system for a motor-driven adjustment part of a motor vehicle, the adjustment system comprising:
- a Hall sensor that is exposed to a magnetic field rotated as a result of a motor rotation;
- a control unit configured to control the Hall sensor for its deactivation and reactivation and configured to control a drive of the adjustment part for a number of approaches of the adjustment part toward an end position and then for a standardization run to the end position;
- and
- a counter, which id adapted to change by a count value upon each approach of the adjustment part toward the end position,
- wherein the control unit detects each deactivation and subsequent activation of the Hall sensor, and
- wherein the counter changes the counter state according to the number of activation and deactivation cycles.
