Definitions

  • the invention relates to a motor vehicle door closure, with a locking mechanism, further comprising an electric drive for the locking mechanism, and with at least one signal generator for acting on the electric drive.
  • the subject of the invention is a method for the motor or electrical actuation of a locking mechanism in a motor vehicle door lock, which is acted upon by means of at least one signal generator of the electric drive.
  • a motor vehicle door lock and an associated method for the electrical actuation of a locking mechanism of the embodiment described above is presented in DE 196 00 524 A1.
  • This is a lock for motor vehicle doors, which is electrically operated and additionally has an emergency opening.
  • a handle such as a door handle or an outside door handle
  • the pawl is brought as part of the locking mechanism by means of an actuating device electrically at least in an open position.
  • This has proven itself in principle and is referred to as so-called "electrical opening" of the motor vehicle door lock, because the actual opening process is not done manually via an operating lever chain, but rather without mechanical connection between the handle and the locking mechanism (only) by electrical means using the electric drive ,
  • Vorrasthakeln is a process in which the self-excavated pawl again comes into mechanical contact with the opening catch. This can be done, for example, that the actuated to open the locking handle released and optionally applied again once, while the locking mechanism still opens or the first-time initiated opening process of the locking mechanism is not yet completed. In any case, this Vorrasthakeln the opening movement of the rotary latch may be delayed or completely prevented. In addition, the opening process is usually accompanied by disturbing noises. A latching lever often occurs in an extremely slow opening operation.
  • the invention is based on the technical problem of further developing such a motor vehicle door lock in such a way that the assembly and production costs are reduced, and in spite of still functioning functionality and in particular while avoiding the pre-doctoring hooks already described.
  • a generic motor vehicle door lock in the context of the invention is characterized in that two edges of a signal generated by the signal generator for controlling the electric drive are evaluated.
  • the electric drive is usually an electric opening drive, ie one which is suitable for electrically opening the locking mechanism.
  • the invention is not limited to this, since the electric drive basically also serves or can serve to represent an unlocking and / or locking function for the locking mechanism.
  • the electric drive is used to open the locking mechanism.
  • the electric drive generally works on a release lever, which in turn lifts the pawl of the catch, so that it can open spring assisted.
  • the electric drive can also act directly on the pawl in an opening sense.
  • the signal generated by the signal generator is now evaluated for the special control of the electric drive described above.
  • the signal generator interacts in this context as usual with a handle and / or a lever connected to the handle.
  • the signal generator may be equipped with a spring tongue for its operation. Unless the handle on the already
  • the lever may be a blocking lever interacting with the electric drive.
  • the blocking lever typically ensures that the electrical drive is blocked when the handle is unloaded.
  • any Fehlbestromungen the electric drive can be structurally controlled. Because such Friedbestromungen not inventively lead to the electrical opening of the locking mechanism, because in this context, the blocking lever holds the electric drive or blocked. Only when the handle is actuated and consequently also acts on the blocking lever, this leaves the electric drive and thus the electric drive can work on the locking mechanism as desired. As a result, a particularly safe operation is provided.
  • the signal transmitter or a microswitch most commonly used at this point is examined and evaluated with regard to the actuating signal generated with its aid. Because the operation of such a signal transmitter or microswitch corresponds to the fact that the signal starts with a slope with a current supply time x for the drive, which also takes into account the wear influences of the drive in order to reach the end position. After the energizing time x, the drive is activated
  • the electric drive goes into a holding phase after a starting phase.
  • the start phase corresponds to a predetermined start time, which begins with the first edge of the signal generator. Since the signal of the signal generator is typically evaluated in a connected control unit, which in turn acts on the electric drive, the above-mentioned start time can be easily stored in the control unit and pretend with their help.
  • the holding phase immediately follows the starting time, which ultimately depends on the time required by the electric drive to completely open the locking mechanism in the example described, or to transfer the locking pawl into its fully lifted position from the catch (end position).
  • the holding phase is not predetermined in time and in principle not limited. Rather, only the beginning of the holding phase is fixed, namely as the end of the starting phase.
  • the holding phase is terminated as soon as the signal generator or the signal generated by it shows the second edge. Like the first edge, so the second edge of the signal generator is registered by the control unit and evaluated accordingly. So as soon as the second edge is observed, the control unit ensures that the holding phase is terminated and a new start can be realized.
  • This edge change is typically associated with the fact that the handle acting directly or indirectly on the signal generator (inner door handle and / or outer door handle) is actuated to open the locking mechanism.
  • the second edge of the signal of the signal generator corresponds to the fact that the relevant handle is released and, for example, spring-assisted resumes its initial position or basic position.
  • the edge change is evaluated by the control unit. This ensures that the current supply for the electric drive is aborted and a new starting process can be initiated. Because the definitely completed start phase within the start time ensures that the electric drive is transferred undisturbed from its basic setting to the end position.
  • the end position of the electric drive corresponds in the example case to the fact that the pawl is lifted from the catch and consequently can open the catch spring-assisted.
  • the basic position in contrast, corresponds to the position in which the electric drive starts and the locking mechanism is (still) unaffected.
  • the holding phase according to the invention which lasts until the signal generator no edge change is generated more, ensures that a Vorrasthakeln is prevented.
  • the electric drive is composed of at least one electric motor, a worm wheel driven thereby and a driven pulley meshing with the worm wheel.
  • the driven pulley may in turn be equipped with an opening contour or an opening cam, which interacts with the release lever acting on the locking mechanism during electrical opening, respectively directly on the
  • the invention also provides the method already described in the introduction for the electrical or motor actuation of a locking mechanism in a motor vehicle door lock, which may have the properties described in the introduction.
  • the electric drive passes through the initiated with the help of the edge change of the signal generator start phase then in the hold phase, which is terminated by the new edge change.
  • After completion of the holding phase of the electric drive is transferred to a neutral position or its basic position.
  • a renewed start command or an opening process initiated by the handle can be processed by the electric drive. So that the electric drive can be transferred from its end position to the neutral position or basic position, the electric drive is typically acted upon by spring force.
  • the holding phase of the electric drive usually corresponds to a short circuit of the electric motor as part of the electric drive.
  • This short circuit of the electric motor ensures that the electric drive assumes a holding function in comparison to the locking mechanism acted upon by it.
  • This holding function ensures that the pawl by means of the electric drive during the holding phase in question is lifted and remains unchanged from the catch, even if the catch has already opened spring-assisted.
  • a pulse control of the drive with a low Votlutton can be used.
  • Fig. 1 and 2 the motor vehicle door lock according to the invention in different functional positions
  • Fig. 3 shows two basic timing diagrams to illustrate the
  • a motor vehicle door lock is shown, which is equipped with a not explicitly shown locking mechanism.
  • the locking mechanism is composed of a catch and a pawl as usual.
  • an electric drive 1, 2, 3 works directly or indirectly.
  • the electric drive 1, 2, 3 is composed of an electric motor 1, an applied by the electric motor 1 screw 2 and finally a meshing with the screw 2 driven pulley 3 together.
  • the driven pulley 3 can perform rotational movements about its axis 4.
  • rotational movements of the driven pulley 3 about the axis 4 in the counterclockwise direction cause the already mentioned pawl is lifted directly or indirectly via a release lever not explicitly shown by their engagement with the rotary latch.
  • the catch can spring-assisted open and release a previously captured locking pin.
  • the locking mechanism is open.
  • the raised position of the pawl in comparison to the rotary latch corresponds to the fact that the electric drive 1, 2, 3 or its driven pulley 3 is driven with its stop 5 in abutment against a housing-fixed counter-stop 6 in the counterclockwise direction.
  • the transition from the basic position shown in FIGS. 1 and 2 (neutral position) or initial position A of the electric drive 1, 2, 3 or the driven pulley 3 in the previously described end position (end position E) with the against the counter-stop 6 driven stop 5 is also clear from FIG. 3.
  • the basic position or initial position A and the end position or end position E of the electric drive 1, 2, 3 are shown in the upper diagram of FIG. If the electric drive 1, 2, 3 is no longer in the end position or end position E, respectively, the associated electric motor 1 does not experience any corresponding action, then a spring 7 which is merely indicated in FIGS. 1 and 2 ensures that the electric drive 1 , 2, 3 assumes its basic position or initial position A spring-assisted.
  • the spring 7 is designed as a center / zero spring 7 and ensures regardless of the direction of actuation of the electric drive 1, 2, 3 respectively, the direction of rotation of the driven pulley 3 about its axis 4 each for that after completion of the application of the electric Drive 1, 2, 3 respectively the basic position or neutral position or initial position A part of the electric drive 1, 2, 3 is taken.
  • Fig. 3 the associated time course of a signal S is then still shown, which is transmitted from a signal generator 8 to a control unit 9.
  • the signal generator 8 is associated with a handle 10.
  • the handle 10 operates on a lever 11 which is designed as a blocking lever 11. Once the handle 10 is acted upon, in the direction of opening, the lever or blocking lever 11 is pivoted about its axis 12 in the clockwise direction, as seen in the transition from Fig. 1 to Fig. 2.
  • the signal generator 8 is in turn equipped with a spring tongue 13. As soon as the handle 10 is acted upon, the signal generator 8 generates a signal S, which changes from “0" to "1” as shown in FIG. The released handle 10 causes the signal S from “1" to "0” falls again. Along with this, a first flank Fs and a second flank FE in the time course of the signal S are observed over the time t in FIG. Both the first edge Fs and the second edge FE of the signal S generated by the signal generator 8 are now evaluated in the context of the invention, specifically for controlling the electric drive 1, 2, 3. For the evaluation, the control unit 9 provides in the example.
  • the overall design is made such that the electric drive 1, 2, 3 is started by means of the first edge Fs of the signal S of the signal generator 8.
  • the first edge Fs corresponds to the fact that the electric drive 1, 2, 3 passes from its normal position A to the end position E or a corresponding current supply from the Control unit 9 learns.
  • the second edge FE of the signal S of the signal generator 8 ensures that the electric drive 1, 2, 3 is switched off. It can be seen on the basis of FIG. 3 that, logically, the second flank FE coincides with the transition of the electric drive 1, 2, 3 from the end position E to the basic position A again.

  • the handle 10 is acted upon, which in turn operates on the blocking lever 11, which in turn acts on the signal generator 8.
  • the blocking lever 11 ensures in the exemplary embodiment that, for example, incorrect energizing of the electric drive 1, 2, 3 can not lead to an unintentional opening of the locking mechanism.
  • the blocking lever 11 is in engagement with the electric drive 1, 2, 3 according to the functional position of FIG. 1 as long as the blocking lever 11 is not pivoted by means of the handle 10 about its axis 12 in the clockwise direction. Only when this happens and the functional position of Fig.
