Definitions
- the invention relates to a control circuit of an electrically operated motor vehicle door lock o. Like. With the features of the preamble of the single claim.
- the invention relates to a control circuit of an electrically operated Motor vehicle door lock or the like, so also suitable for other types of lock Crane vehicles such as locks on rear doors, tailgates or hoods.
- a known motor vehicle door lock has a lock latch and a lock latch pawl holding in the closed position and an electromotive auxiliary locking drive on. This is switched on after the lock latch has reached a pre-closing position has reached and then transfers the lock latch to the main closed position by motor.
- the pre-locking position can be reached act or a specific position of the motor vehicle door in relation to the body, for example with a remaining gap of 6 mm.
- control circuit is made so that the lock latch next to the switching position recognizing the switching position A second switching encoder that detects the closed position is assigned When the closed position is reached and the pawl engages in the main catch the lock latch causes this second switching encoder to switch off the electromotive Auxiliary closing drive.
- a control circuit that controls an electromotive auxiliary locking drive with just a single one recognizing the locking position of the lock latch, switching encoder guaranteed, is known from GB 2 295 642 A in this the starting point of the control circuit forming the invention are the lock latch and the only encoder arranged relative to one another such that the encoder at Lock position located lock latch is actuated.
- This will activate the auxiliary locking drive driven in a first direction of rotation and the lock latch in the Main closed position transferred.
- the auxiliary locking drive runs for so long in the first Direction of rotation until the lock latch comes into an overstroke position and thereby the Switching off the encoder Switching off the encoder causes the locking auxiliary drive to move in a second direction of rotation opposite to the first direction of rotation. This causes the lock latch to return to its main closed position.
- the termination the movement of the locking auxiliary drive in the second direction is determined by overcurrent shutdown reached.
- Another known control circuit (DE 195 46 383 A1) has an encoder the first time it reaches the locking position through the lock latch is turned on, and the movement of the lock latch towards the main closed position initially switched off and when the main closing position is reached is switched on again.
- the auxiliary locking drive is activated when the encoder is switched on for the first time activated, thereby moving the lock latch to the main closed position.
- the second time the encoder is switched on it can be detected that the Main closed position is reached, so that the auxiliary locking drive in the opposite Direction is moved and reaches its starting position.
- the lock latch has assumed its basic position is a special one intended for this purpose Control component provided.
- the invention has for its object a control circuit of an electrical actuated motor vehicle door lock or the like. Specify, which is even simpler is. This object is achieved by the features of the characterizing Part of the single claim solved.
- a single switching encoder is provided, which at least the Preset position, possibly also by a corresponding shape of the lock latch Detects or senses the main closing position.
- This encoder only needs to be in an appropriate Control circuit can be implemented.
- Fig. 1 shows a schematically illustrated embodiment of a motor vehicle door lock o. Like., It being understood that similar constructions for Locks on other parts of a motor vehicle body, ie for rear doors, tailgates or hoods can be used.
- the motor vehicle door lock shown that is, for the side door of the motor vehicle is determined, first has a lock latch 1 and a lock latch 1 in Pawl 2 holding the closed position.
- a locking bolt 3 is also indicated as an example of a counter element for the door lock.
- An electromotive is provided Auxiliary locking drive 4, which is an electrical in the illustrated embodiment Has drive motor 5, which drives a worm wheel 7 via a worm 6, which is coupled to a coaxial spur gear 8 via an intermediate one Spur gear 9 and a third spur gear 10, an output shaft 11 is moved, which at its rear end portion carries a lever 12. Coaxial to the output shaft 11, however separated from it, the pivot axis of the lock latch 1 is arranged.
- the lever 12 grips the lock latch 1 on a driving projection 14.
- Fig. 1 shows the closed position of the lock latch 1 with the sunken in the main catch 13 Pawl 2.
- the pawl 2 can also engage in the preliminary catch 15.
- Right away is located behind the pre-locking position in the direction of the main locking position the pre-closed position of the lock latch 1 in the illustrated embodiment corresponds, for example, to a body distance with a remaining gap of 6 mm.
- the electromotive locking auxiliary drive 4 is switched on after the lock latch 1 has reached the pre-closing position.
- the lock latch 1 is then motorized in transfers the main closed position, in that the lever 12 the driving projection 14 on the lock latch 1 pushes in front of it until it is shown in FIG. 1 Has reached the closed position with the pawl 2 engaged.
- Switches 16 which recognizes the pre-closing position and which according to the illustrated and so far preferred example, the position of Lock latch 1 scanning lock latch switch is in the illustrated embodiment is an electromechanical microswitch, whose switching plunger is actuated via a control cam 17 on the lock latch 1. From the state of the Technology is also a contactless switch, for example with Hall sensors etc. known.
- the motor vehicle door lock shown in Fig. 1 is one in which when switched off or if the drive energy fails for the auxiliary locking drive 4 Auxiliary locking drive 4 is automatically decoupled from the lock latch 1.
- This can be Realize that the auxiliary locking drive 4 when the power supply to the drive motor ceases to exist 5 is returned to its starting position by a spring, which can but can also be realized by an electromagnetic clutch in the auxiliary locking drive 4, which will be released at the appropriate moment.
- the latter has the other Advantage that an emergency interruption of the power chain while running Drive can be achieved. This is based on a parallel submitted at the same time Reference to the applicant's patent application.
- Fig. 2 now shows the extremely simple control circuit of the example in Fig. 1 shown electrically operated motor vehicle door lock. shown is that the negative pole 18 of the auxiliary locking drive 4 or the electric drive motor 5 of the auxiliary locking drive 4 is connected to ground or negative potential and the positive pole 19 is switched and either at the positive potential of the vehicle electrical system voltage is or is grounded or is open (floated).
- the encoder 16 is between Ground and a switching connection 20.
- optional electromagnetic clutch 21 without this here must be explained further.
- the illustrated embodiment shows that the encoder 16 is designed as a closer is, that is to say when the pre-closing position is reached and closes the switching connection 20 Mass connects.
- Fig. 1 makes it clear that the encoder 16 when reaching a little beyond the closed position switches the overstroke position of the lock latch 1.
- a continuous control curve 17 control the encoder 16.
- the encoder 16 can also be controlled by two switching pulses and between the switching pulses maintain its switching state. This is a control technology that is for contactless actuated switches can be used rather soon.
- auxiliary locking drive 4 when reaching something beyond Automatically switches off the overtravel position of the lock latch 1, that in particular the positive pole 19 of the auxiliary locking drive 4 then to ground or Minus potential is or is open
- FIG. 3 shows the potentials for the illustrated and preferred exemplary embodiment at the connections 18, 19, 20 than at the negative pole 18, at the positive pole 19 and at the switching connection 20, for the various phases of actuation of the motor vehicle door lock.
- the potential curve at the switching connection 20 and the positive pole 19 shows accordingly Fig. 4.
