Motor vehicle door lock with an electromechanical central locking system drive
First Claim
1. Motor vehicle door lock with 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 with a motor state sensor, and the central locking system element being movable by the central locking system drive at least into a locked position, and the motor control being adapted to trigger the electric drive motor for driving the central locking system element into the locked position after receiving an actuation signal from an actuation unit, wherein the motor control has a control circuit that includes the motor state sensor, and wherein the control circuit is adapted to cause the electric drive motor to run at low rpm when the electric drive motor is triggered and wherein the control circuit is adapted to control the drive motor rpm in accordance with a signal of the motor state sensor.

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).
