Definitions

  • the present invention relates to a motor vehicle door locking system according to the preamble of claim 1, an outer door handle assembly for a motor vehicle door locking system according to the preamble of claim 14 and a Method for controlling a motor vehicle door locking system according to the Preamble of claim 18.
  • the "passive entry" function includes an automatic, Motor vehicle-side data query or identification of an operator-side Understand data carrier, transponders or the like. To determine whether a an operator approaching the motor vehicle or an operator, which is already in the process of the motor vehicle or a motor vehicle door is open to access. This is mostly from a corresponding one Electronics of the motor vehicle checked. With appropriate Authorization of the operator is usually automatic Unlock either a central locking system, the driver's door lock or at least the door lock of the door that the operator is concerned with approaches or whose outside door handle touches or actuates the operator.
  • a motor vehicle door locking system with a "passive entry" function is required for the control electronics a specific reaction phase or time, which from a startup interval to the system when the disk approaches or remote control module, an authorization check interval to the operator based on the coding of the between remote control module and control electronics to check exchanged signals for their authorization, and finally the actual interval of action in which the action is carried out, in particular the unlocking of the motor vehicle lock is put together.
  • an appropriate reaction phase is required when locking the motor vehicle door locking system. This is but less critical because the operator hardly notices it.
  • the duration of the reaction phase of more than a hundred milliseconds is in the Compared to conventional motor vehicle door locking systems as long felt if the start-up interval only when the outer door handle is actuated starts. Pulling the outer door handle or the like can namely with a "passive Entry "function may already take place when the reaction phase of the Control electronics has not yet been completed. The operator must then pull the outer door handle a second time, which is a "malfunction" can be interpreted.
  • Another approach is the start-up interval of the control electronics not to start only when the outer door handle is actuated, but already an operator's hand approaching the outside door handle to start the start-up interval. It is known to do this on the outside door handle to provide a capacitive proximity sensor (DE - A - 197 52 974; DE - A - 196 17 038), by which the hand of the operator approaches already about 100 to 150 ms before touching the outside door handle is grasped by hand.

  • the access system has an antenna and an identification means for checking the access authorization a data carrier on the operator side, if there is a Operator is located with the disk in a surveillance area.
  • the access system also has a proximity sensor that the Access system activated when an operator is in the surveillance area located.
  • the proximity sensor is preferably a capacitive proximity sensor.
  • magnetic, Inductive, acoustic and similar proximity sensors can be used designated. It becomes a preferred arrangement of the access system and hence the proximity sensor in the area of the A-pillar or the B-pillar of a motor vehicle disclosed. Ultimately, it is a type "Antenna system" with extensive radiation.
  • the present invention is based on the object of a motor vehicle door locking system, an outer door handle assembly for a motor vehicle door locking system and a method for controlling a motor vehicle door locking system to create a simple, inexpensive way Approaching, in particular an operator's hand, an outside door handle and / or touching the outside door handle in proportion low energy consumption and good response behavior can be detected can, in particular where then a "passive entry" function of the motor vehicle door locking system activated or a start-up interval of control electronics can be started.
  • a basic idea of the present invention is ultrasonic waves for the detection of an approach, in particular an operator's hand, to the outside door handle and / or touching the outside door handle, especially by one hand of an operator, in a near field.
  • “Ultrasound” here means vibrations or sound waves with frequencies above the hearing range, in particular above approximately 16 or 20 kHz and preferably up to approximately 8 ⁇ 10 9 Hz. This ensures that the sound waves emitted for detection purposes are not audible.
  • Another advantage of using ultrasonic waves is that with a relatively low energy requirement, a good response in terms of proximity or touch sensing can be achieved can.
  • Another fundamental aspect of the present invention is that at least essentially exclusively in the area or nearby of the outside door handle an ultrasound field is generated. This enables one extensive minimization of the energy requirement, since only a relative to monitor a small area is still sufficient early detection of an approach or touch is possible.
  • an ultrasonic transducer for transmission and / or detecting ultrasonic waves arranged directly on the outside door handle is.
  • ultrasonic transducer is here in particular a device or a component for converting electrical signals into ultrasonic waves and / or vice versa.

  • the evaluation can in particular directly in electronics assigned to the sensor and / or in a separate evaluation electronics or the like. This poses It goes without saying for the person skilled in the art, so that no further details are given is dealt with, since it does not primarily matter where the evaluation takes place. However, it is advantageous if the corresponding detection signal available evaluation electronics already in the outside door handle or an outer door handle arrangement is integrated.
  • the preferably integrated arrangement of the ultrasonic transducer on the outside door handle enables a relatively simple retrofitting or introduction for motor vehicles that are already in production, since only a correspondingly modified outside door handle with assigned control and / or evaluation electronics instead of a conventional door handle must be used.
  • Approaching the outside door handle and / or touching the outside door handle is preferably by one of the following ways or combinations of which detected or detected.
  • a particularly simple and inexpensive embodiment provides that the ultrasonic transducer works both as a sensor and as a receiver. In particular with a pulsed generation of the ultrasonic wave then the ultrasonic transducer works as a receiver in the pulse pauses.

  • ultrasonic waves exclusively from an approximated object to be detected, such as a hand Operator, and not from the outside door handle and / or an adjacent one Door area to be reflected back to the ultrasonic transducer.

  • the least two ultrasonic transducers are then preferably on the outside door handle in this way arranged that an ultrasonic field like a light barrier is formed, the interruption is detectable as an approach and / or touch.
  • the sound propagation between the two ultrasonic transducers must, however not straight. Rather, for example, on one neighboring door area, such as a recessed grip, reflected ultrasonic waves be detected by the additional ultrasonic transducer. In that case, you can Transmitter and receiver, for example, arranged closer or next to each other become.
  • the proximity and / or touch sensing enables early detection Activate the "Passive Entry” function or start the start-up interval control electronics. Enough time is saved, for example unlock a motor vehicle lock before the detected operator actually the outside door handle to open the corresponding one Motor vehicle door or the corresponding motor vehicle lock operated.

So, in particular if this adjacent door area belongs to an outer door handle arrangement, which as a separate part or separate unit in the assigned motor vehicle door is used, the installation in the motor vehicle door is simplified become an electrical connection to the ultrasonic transducer, since the difficulty is eliminated in the usually moveable outer door handle to manufacture.
