Embodiment Construction

[0025] The drawing shows a motor vehicle door lock with a locking device (not shown in detail) comprising a rotary locking fork and a locking pawl. The release lever 1 acts on the locking device or locking pawl, the release lever is in figure 1 is only shown in section and is connected to the central locking lever 2 . In the exemplary embodiment, the central locking lever 2 is coupled to an inner locking lever 3 , on which an inner locking element or inner locking rod 4 in turn acts. However, instead of the inner locking element 4 and the inner locking lever 3 , an outer locking device having a corresponding outer locking lever, an outer locking element and the shown key 5 as well as a corresponding lock cylinder 6 can also be realized here.

[0026] The central locking element 2 is acted upon by a control element 7 in the form of an output wheel with two eccentric control pins 8 . For this purpose, the control pin 8 engages in the fork-shaped receptacle 9 of the central loc...

Abstract

The invention relates to a motor vehicle door lock, having a lever chain (2 to 6) which can be acted upon by a motor, and having an electric motor (10) featuring an associated control unit (11), wherein the electric motor (10) moves the lever chain (2 to 6) into a predetermined position or, starting from the predetermined position, acts thereon, and wherein the control unit (11) uses data of the electric motor (10) for acting thereon. According to the invention the control unit (11) evaluates gradients of performance data of the electric motor (10) for adjusting the position of the lever chain (2 to 6).

Description

technical field [0001] The invention relates to a motor vehicle door lock comprising a motorized loadable lever system and an electric motor with a corresponding control unit, wherein the motor moves the lever system to a predetermined position or loads the lever system from a predetermined position , wherein the control unit uses the data of the electric motor for the loading of the electric motor. Background technique [0002] In motor vehicle door locks of the above-described configuration, such as those described in the corresponding DE 44 47 687 C2 or in the corresponding US 5 634 677, the control element is acted upon electromechanically. The impact of the control element on the stop surface of the fork-shaped receptacle is detected by the associated increased current consumption or by time control, and the electromechanical drive is thereby switched off. Finally, the motor is switched off in case a certain threshold of current drawn by the motor is exceeded. [0003...
