Definitions
- the present invention relates to a motor vehicle lock according to the preamble of claim 1 and a method for operating a motor vehicle lock according to claim 5.
- the motor vehicle lock in question can be assigned to any flap of a motor vehicle.
- These include tailgates, boot lids, front hoods, in particular engine hoods, side doors, tailgates or the like.
- These flaps can be pivoted or designed in the manner of sliding doors.
- the closing aid ensures motorized adjustment of the lock latch of the motor vehicle lock from an initial position, preferably from a pre-closed position, into a main closed position, which, for example, involves pulling the respective flap from a pre-locked position into a main locked position. It is precisely this last part of the closing movement of the flap that requires a considerable application of force against the pressure of the door seal, so that the motorized adjustment of the lock latch improves comfort.
- the closing aid increases user-friendliness in a very intuitive way, the motorized adjustment of the latch also involves a certain risk of injury. The reason is that in the starting position in the Usually a certain gap between the flap and the body remains. When the closing aid is activated, a considerable force acts on an object in the gap, in particular a finger, which can lead to serious injuries.
- the well-known motor vehicle lock (US 2020/0024875 A1) provides a mechanical overload clutch for the closing drive, with which a transmission of excessive forces in a first section of the adjustment of the latch bolt is avoided.
- the invention is based on the problem of designing and developing the known motor vehicle lock in such a way that further optimization is achieved with regard to the challenge mentioned.
- the control arrangement controls the closing drive in the closing routine, to move the latch from the initial position into a delay position for carrying out a delay action and then to move the latch to the main closed position.
- FIG. 1 shows a schematic perspective representation of a motor vehicle with a proposed motor vehicle lock
- the drawing shows a proposed motor vehicle lock 1 that can be used for all conceivable flaps 2 of a motor vehicle 3 .
- the motor vehicle lock 1 is preferably arranged in or on the respective flap 2 .
- the motor vehicle lock 1 can also be arranged in or on the motor vehicle body (not shown).
- the proposed motor vehicle lock 1 is equipped with a lock latch 4 for holding engagement with a locking part 5 and a pawl 6 equipped.
- the locking part 5 can be designed as a locking bolt, locking bracket, locking wedge or the like.
- the closing part 5 is arranged on the motor vehicle body in the exemplary embodiment shown and in this respect preferred.
- the lock latch 4 is shown in the illustrations according to FIG. 2a) in its main closed position (dashed lines) and in an initial position, preferably a pre-closed position (continuous lines). In the open position (not shown), the lock latch 4 releases the locking part 5 .
- the pawl 6 blocks in the sunken position shown an opening of the latch 4 and releases the latch 4 in a raised position.
- the pawl 6 is preferably provided for locking the latch bolt 4 both in the main locking position and in the pre-locking position.
- the exemplary embodiment illustrated in the figures and in this respect preferred relates to a motor vehicle lock for a flap 2 of a motor vehicle 3, the motor vehicle lock 1 being equipped with a lock latch 4 for holding engagement with a locking part 5 and a pawl 6 assigned to the lock latch 4, which is in the closed position blocks opening of the lock latch 4 and in a raised position the lock latch 4 releases, the motor vehicle lock 1 having an electric closing drive 7 and a control arrangement 8, the control arrangement 8 controlling the closing drive 7 in a closing routine, the lock latch 4 in the closing direction from an initial position, preferably from a pre-closing position, to adjust in a main closed position.
- the electric closing drive 7 is here and preferably arranged separately from a lock housing 9, which the Latch 4 and the pawl 6 receives.
- To the pulling drive 7 is here equipped with a transmission means 10, such as a Bowden cable, in order to transmit the driving force generated to the latch 4. It is also conceivable that the closing drive 7 on the
- Closing part 5 acts.
- the lock latch 4 is adjusted in the closing direction to the main closed position. As will be clear below, the lock latch 4 in the
- Closing routine can also be temporarily adjusted against the closing direction.
- the starting position preferably the pre-locked position
- the starting position is provided between the open position and the main closed position of the lock latch 4 .
- the starting position there is a gap 11 between the flap 2 and the motor vehicle body, into which an object 12 such as a finger can penetrate.
- the control arrangement 8 can be designed as part of the flap control unit assigned to the flap 2 and which interacts with a higher-level motor vehicle control system.
- the control arrangement 8 can also be integrated in the lock housing 9 .
- the control arrangement 8 can also be part of a central motor vehicle control system.
- the control arrangement 8 preferably has an electronic control system for implementing the control tasks occurring in the closing routine. It is now essential that the control arrangement 8 controls the closing drive 7 in the closing routine, to adjust the lock latch 4 from the initial position into a delay position in order to carry out a delay action and then to adjust the lock latch 4 into the main closed position.
- the deceleration position is preferably provided between the initial position and the main closed position.
- a delay position between the open position and the initial position can also be provided, with the lock latch 4 being adjusted, for example, initially in the opposite direction to the closing direction and then brought into the main closed position after the delay action.
- the delay action generally causes a delay in the closing routine compared to driving the closing drive 7 without the delay action. The operator is thus given the opportunity to remove the object 12 from the gap 11 .
- the delay caused by the delay action is, for example, at least one second and/or at most ten seconds.
- Fig. 2b shows exemplary movements of the lock case 4 in the closing routine.
- the starting position is illustrated here using the pre-locking position VR and the main closed position using the main locking position HR of the flap 2 .
- the delay position in turn corresponds to an intermediate position ZS of flap 2.
- the lock latch 4 is initially adjusted to the deceleration position.
- the control remains in the deceleration action for a predetermined time span off.
- the lock latch 4 remains in the delayed position for this period of time.
- the adjustment to the main closed position is continued.
- the actuation before and after the deceleration action is provided in the same way, for example with the same drive voltage U.
- the closing drive 7 is activated to keep the lock latch 4 active in the deceleration position, for example via generator operation of an electric motor of the closing drive 7.
- control arrangement 8 controls the closing drive 7 in the deceleration action to adjust the lock latch 4 in the opposite direction to the closing direction, which is achieved here by a drive voltage U'. is effected with opposite polarity.
- the lock latch 4 accordingly leaves the deceleration position in the deceleration action.
- Reaching the decelerated position can preferably be detected by means of the control arrangement 8 via a sensor, more preferably a switch assigned to the lock latch 4 and/or a motion sensor assigned to the closing drive 7 . It is also conceivable for the closing drive 7 to be determined by means of the control arrangement 7 when the decelerated position is reached based on the drive values, for example based on the current ripple in the drive current. In a particularly simple embodiment, it can also be provided that the closing drive 7 is initially energized for a predetermined period of time, which is not sufficient for the main locking position to be reached. In this respect, the deceleration position is not necessarily to be understood as a firmly defined spatial position that is clearly determined by the control arrangement 8 . It is further provided here and preferably that the control arrangement 8 controls the closing drive 7 in the closing routine to move the lock latch 4 successively into a plurality of delay positions in order to carry out the respective delay actions.
- control arrangement 8 in the closing routine preferably with the adjustment of the lock latch 4 into the decelerated position and/or with the deceleration action, the output of a warning signal, preferably via an optical and/or or audible warning device.
- the output of the warning signal can provide the operator with the initiation of the closing routine in addition to the adjustment of the lock latch 4 to the deceleration position.
- the optical and/or acoustic warning device is not necessarily part of the motor vehicle lock 1.
- an output device provided on the motor vehicle 3 for other purposes, for example lighting or the like, can be used as a warning device.
- a method for operating a motor vehicle lock for a flap 2 of a motor vehicle 3 is also claimed, the motor vehicle lock 1 having a ner lock latch 4 is equipped for the holding engagement with a locking part 5 and a pawl 6 assigned to the lock latch 4, which blocks opening of the lock latch 4 in the closed position and releases the lock latch 4 in a raised position, with the motor vehicle lock 1 having an electric has a closing drive 7 and a control arrangement 8, with the closing drive 7 being controlled by the control arrangement 8 in a closing routine to move the latch 4 in the closing direction from an initial position, preferably from a pre-closed position, into a main closed position, with the closing start drive 7 is controlled by means of the control arrangement 8 in the closing routine the closing drive 7, to adjust the latch 4 from the initial position into a delay position to carry out a delay action and then to adjust the latch 4 into the main closed position.
