Definitions

  • the invention relates to a motor vehicle lock, in particular an electric lock, with a locking mechanism consisting essentially of a rotary latch and a pawl, furthermore with an electric motor opening drive for the locking mechanism, and with an energy storage device for emergency power supply to the opening drive and thus for emergency opening of the locking mechanism in emergency operation.
  • Motor vehicle locks and in particular electric locks, are characterized by the fact that they offer the user a special level of convenience when opening a corresponding motor vehicle door.
  • the motor vehicle door can generally be a side door, but also a tailgate, a fuel filler flap, a loading flap, etc.
  • the opening process is usually initiated by a remote control or by the operator activating a sensor or switch. This can be located, for example, on or in an outside door handle.
  • a drive arrangement for a motor vehicle lock which is equipped with a main drive operating on an actuating lever mechanism. Furthermore, an auxiliary drive is implemented for emergency unlocking or emergency opening of a locking mechanism.
  • the auxiliary drive is designed as a component of an auxiliary module that is mechanically connected to the motor vehicle door lock and functionally independent.
  • the auxiliary module can, in turn, be equipped with an energy source or auxiliary energy source. This is an accumulator, one or more capacitors, or combinations thereof.
  • a generic motor vehicle lock and in particular an electric lock is required within the framework of Invention characterized in that the electronic reset is carried out by querying at least one sensor.
  • the invention therefore fundamentally operates in such a way that emergency operation corresponds to the locking mechanism assuming its open state during or following an emergency opening and maintaining this open state.
  • emergency operation this is generally ensured by the energy storage device for emergency powering the opening drive.
  • the main energy source used in normal operation to power the electric motor opening drive for example, a battery in the vehicle, has usually failed or is not delivering sufficient power to move the electric motor opening drive.
  • the energy storage device which is designed independently of the main energy source.
  • emergency operation can occur, for example, when a motor vehicle has been parked for an extended period of time and the voltage of the vehicle's main power source has dropped so low that it is no longer able to power the electric motor opening drive for the locking mechanism.
  • the system switches to emergency operation in such a case, for example when the operating voltage provided by the main power source falls below the level provided. This means that the locking mechanism remains closed and unchanged when the vehicle is parked. Only when a user in emergency operation enters a If someone wants to open the vehicle door belonging to the vehicle, for example by operating a sensor or a remote control, the emergency opening is initiated.
  • This opening process is usually carried out by the operator actuating a door actuation switch 8, 9.
  • two door actuation switches 8, 9 are implemented, namely an interior door actuation switch 8 and an exterior door actuation switch 9.
  • the opening process is usually initiated by the operator actuating the exterior door actuation switch 9. This applies both in normal operation and in emergency operation.
  • the opening drive 3, powered by the energy storage device 4, ensures that the locking mechanism 1, 2 not only assumes its “open” state, but is also held in this "open” state by the opening drive 3 until a reset occurs.
  • the control unit 5 which detects the emergency operation and actuates the opening drive 3 accordingly.
  • an electronic reset is implemented. During this reset, the locking mechanism 1, 2 returns to its closed basic position.
  • the opening drive 3 is powered by the control unit 5 and supplied by the energy storage device 4 in such a way that the pawl 2 is no longer held at a distance from the rotary latch 1.
  • the opening drive 3 releases the pawl 2 so that it can, for example, spring-assistedly return to its Fig. 1
  • the pawl 2 can then fall back into its locking position, as shown in the Fig. 1 is shown.
  • the electronic reset and the release of the locking pawl 2 are initiated by querying at least one sensor 8, 9.
  • the sensor 8, 9 is the two door operating switches 8, 9. This means that the actuation of these two sensors 8, 9 or the door operating switches 8, 9 corresponds to the electronic reset. This is initiated when a predetermined actuation sequence of the two sensors 8, 9 or the door operating switches 8, 9 is observed.
  • this actuation sequence corresponds to both the interior door actuation switch 8 and the exterior door actuation switch 9 being actuated simultaneously.
  • the control unit 5 sends a signal to the electromotive opening drive 3 so that it releases the locking pawl 2 so that the locking pawl 2 can move from its raised position into the closed position as shown in the Fig. 1 can return with spring support.
  • the motor vehicle door equipped with the illustrated motor vehicle lock or motor vehicle door lock can now be closed again.
  • each door opening requires a subsequent electronic reset. This immediately alerts the operator to the emergency mode, as they cannot close the respective vehicle door with the associated vehicle lock until the described operating sequence has been completed.
