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.

Method for determining the set position of an adjustment part

An electric window lifter of a vehicle with a vehicle door having a frameless window is actuated according to a novel, low-wear actuation method. An entry signal is acquired that allows a conclusion to be drawn about whether a person has entered through this vehicle door. In this case, the window pane that is associated with the window of this given vehicle door is lowered by a short stroke by way of the window lifter in response to a central exit signal only when the entry signal was first identified. The window lifter or power window assembly includes an associated actuation unit with a query module that is configured for automatically carrying out the method.
