Abstract

A motor vehicle door lock system with at least one vehicle lock, an outside door handle assigned to the vehicle lock, and at least one sensor assigned to the outside door handle, where the system is adapted to detect the approach of the hand of an operator to the outside door handle and/or touching and/or activating of the outside door handle. In one embodiment of motor vehicle door lock system, the activation of the outside handle by the hand of an operator or the approach to the outside door handle is recognized early. A vibration generator is assigned to the outside door handle such that the outside door handle or a part thereof is mechanically vibrated. A sensor is provided for acquiring the vibration, the sound waves caused by the vibration and/or their reflections so that the motor vehicle door lock system can detect when the outside door handle or a part thereof is being approached and/or touched and/or activated by the hand of an operator.
