  • a safety device locks can be equipped with systems for electrical opening.
  • An electric opening describes the function in which the operator manually actuates the internal operating lever or the outside door handle, but in which the actual opening of the lock takes place by means of a mostly electric drive.
  • an external operating lever only a signal generator, such as a switch, actuate, so that an electrical signal is generated, whereby the drive is activated by means of a control unit.
  • the external actuating lever may be mechanically connected to an actuating lever in a motor vehicle lock and, for example, make a pivoting movement.
  • the actuating lever can then in turn actuate a switching means or a signal generator, which in turn conducts a signal to the control unit, so that the drive is in turn activated.
  • An electrical opening thus describes an opening triggered by means of a drive, that is to say an unlocking of the locking mechanism.
  • the electric drive may be connected to a transmission and a drive pulley, which then interacts with a release lever and the release lever mechanically unlocks the locking mechanism.
  • a motor vehicle lock with a mechanism for electrical opening is known from DE 10 2012 003 743 A1.
  • An electric drive consisting of motor, worm and driven pulley can set in operation a trip lever in motion, the release lever acts directly on the pawl and the locking mechanism consisting of catch and pawl, unlocked.
  • An actuating lever which may be, for example, an internal operating lever or an external operating lever, acts after actuation by means of the outer handle or the inner door handle with a signal generator, which in turn activates the electric drive via a control unit.
  • the motor vehicle lock is in the locked state, ie the lock is electrically opened, without a mechanical operative connection between the actuating lever and the release lever.
  • Actuating lever and release lever are mechanically decoupled by means of the locking device. Only in the case in which an emergency operation is necessary, for example in the case of a current drop, does the electric drive move in a direction opposite to the opening direction and unlocks the motor vehicle lock. In this case, an operator then has the opportunity to mechanically actuate the operating lever and bring the trigger lever into engagement with the ratchet so that the flap, door or sliding door can be opened.
  • the object is to improve a known method for controlling a motor vehicle lock.
  • the object is to provide methods with which the structure can be simplified without the functional scope being reduced or ensured. to remove important functions from functions.

  • a pre-locking position is the position of the door, flap or hood, in which the door is already closed and held by means of the locking mechanism in position and in particular in a locking position.
  • the motor vehicle door is then transferred from the pre-latching position to the main latching position by means of a mostly electric drive, in which the door is in the fully closed position.
  • the child safety device If the child safety device is switched on or engaged, and the motor vehicle lock is transferred from the pre-rest to the main rest position by means of the closing drive, then the door can be opened by means of the internal operating lever.

  • the locking sensor By integrating the locking sensor is another signal available with which a statement about the closed position of the door is possible.
  • activation of the electric drive to open the door can take place by means of the control unit when the internal operating lever is actuated. A mechanical interpretation of parental control is therefore not required.
  • the position of the locking mechanism can be detected in the pre-detent and the main detent. If by means of the locking sensor the immediate position of the locking mechanism in the pre-locking and main locking can be detected, a control unit can bridge the child-protection sensor signal and thus give an operator of the inside actuating lever the opportunity to open the door or interrupt a closing operation and to interrupt a closing.
  • the locking sensor may be arranged on the rotary latch.
  • An immediate query of the position of the catch harbors a high degree of security in itself. Is the Rotary latch in its end position, that is to say in the position in which the door is completely closed, and if exactly this position is interrogated by means of the locking sensor, then malfunctions can be prevented with the greatest possible certainty.

  • the actuating lever is designed as a pivotally mounted lever.
  • the inside operating lever, the outside operating lever and the tripping lever are supported on a common axis.
  • the clutch lever may be engaged with the release lever by a sliding movement of the inner operating lever and / or the outer operating lever depending on the position of the clutch lever.
  • the clutch lever is moved by means of a likewise pivotally mounted locking lever. In a first position of the clutch lever, the inner operation lever and the outer operation lever are coupled to the release lever, that is mechanically engaged. In this position, the external actuating lever can be moved by an actuation, for example, of an outer door handle, and the locking mechanism can be mechanically and electrically unlocked, thus opening the motor vehicle lock.
