Motor vehicle door lock with an electromechanical central locking system drive
First Claim
1. Motor vehicle door lock, comprising:
- an electromechanical central locking system drive and a mechanical central locking system element in driven connection with electromechanical central locking system drive, the central locking system drive having an electric drive motor and a motor control having a control circuit with a motor state sensor, wherein the central locking system drive comprises a means for moving the central locking system element at least into a locked position, and wherein the motor control comprises a means far triggering the electric drive motor for driving the central locking system element into the locked position after receiving an actuating signal from an actuation unit, wherein the control circuit comprises a means for causing the electric drive motor to run at an rpm which is a minimum possible rpm for a then existing instantaneous operating state in accordance with a signal of the motor state sensor; and
wherein the motor control further comprises a means for automatically triggering the electric drive motor for driving the central locking system element into the locked position as soon as a predetermined operating state of the motor vehicle has been reached.

Abstract
A motor vehicle door lock with an electromechanical central locking system drive (1) and a mechanical central locking system element (2) driven by it, the central locking system drive (1) having an electric drive motor (3) and a motor control (5) with a motor state sensor (6). The central locking system element (2) can be moved by the central locking system drive (1) at least into a locked position and the motor control (5) is designed such that it triggers the electric drive motor (3) for driving the central locking system element (2) into the locked position after receiving an actuation signal from an actuation unit, such as a closing cylinder, a locking button, a remote control receiving unit or a handle (inside door handle, outside door handle). Preferably, the motor control 5 is also designed such that it automatically triggers the electric drive motor (3) for driving the central locking system element (2) into the locked position as soon as a certain operating state of the motor vehicle has been reached. Furthermore, significantly, the motor control (5) has a control circuit that includes the motor state sensor (6) and this control circuit is designed such that, when the electric drive motor (3) is triggered, the electric drive motor (3) runs with a low rpm that is controlled using the signal of the motor state sensor (6).
