Embodiment Construction

[0032] specific implementation plan

[0033] figure 1 An electric window regulator 2 is shown schematically with a window pane 4 , wherein the window regulator 2 is integrated in a door 6 of a motor vehicle. The window pane 4 is advanced along an adjustment path 10 by means of an adjustment drive 8 . The adjusting drive 8 includes an electric motor 12 , to which a worm gear 14 is assigned on the shaft side, by means of which the rotational movement of the electric motor 12 is converted into a translation of the window pane 4 . As soon as the motor vehicle occupant initiates the adjustment movement of the window pane 4 along the adjustment path 10 using the operating button 18 , the electric motor 12 is powered by the motor electronics 16 . Also integrated in the motor electronics 16 (also referred to as control electronics) is an anti-pinch protection which prevents the windshield 4 from pinching objects lying within the adjustment path 10 .

Abstract

A method operates a brushed commutator motor of an adjusting drive in a motor vehicle, particularly a window lifter, having a rotor and having a stator. An angular position of the rotor with respect to the stator is determined. The angular position is used to determine a ripple within the torque, which ripple can be expected on the basis of the commutation. The motor current is adapted such that the amplitude of the ripple that can be expected remains below a determined limit value.

Description

technical field [0001] The invention relates to a method for operating a brushed commutator motor of an adjusting drive having such a commutator motor and to an adjusting drive of a motor vehicle. Part of the adjustment drive, especially the power window. Background technique [0002] Motor vehicles usually include adjustment elements, such as side windows and / or sliding sunroofs, which can be opened and closed using an electric adjustment drive. The seat, or at least parts of the seat, also have electric seat adjustment. The individual adjusting elements are moved by means of a transmission driven by an electric motor, in particular in the form of a worm gear with a worm (drive side) and a worm gear (output side) on the motor shaft. Conventionally, the transmission is arranged in a transmission housing, to which the electric motor is flanged via its motor housing (pole pot). The electric motor is usually fastened on its end side to the transmission housing, wherein the j...
