Definitions

  • the invention relates to a motor vehicle door lock, 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, wherein both a first edge and a second edge of a signal generated by the signal generator for controlling the electric drive be evaluated.
  • the subject matter of the invention is a method for the motorized or electrical actuation of a locking mechanism in a motor vehicle door lock according to the preamble of claim 11.
  • a motor vehicle door lock and an associated method for the electrical actuation of a locking mechanism of the embodiment described above is described in the US 2005/0200137 A1 described.
  • the procedure is such that the electric drive ensures a closing operation.
  • the signal transmitter is associated with a locking pin whose movement is scanned during the closing operation.
  • 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, by releasing the handle actuated to open the locking mechanism and, if necessary, applying it once more, namely while the locking mechanism is still in the open or the opening procedure of the locking mechanism initiated for the first time has not yet been 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 is within the scope of the invention characterized in that the electric drive is designed as an electric opening drive for electrically opening the locking mechanism and, after a initiated by the first edge of the signal generator start phase in a holding phase, which via a Edge change is terminated by the second edge, or vice versa, wherein the completed in any case starting phase within a start time ensures that the electric drive is transferred undisturbed from its basic position to an end position, and wherein the electric drive transferred after completion of the holding phase in the basic position becomes.
  • a new start command can be processed.
  • the electric drive thus serves 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 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 generator 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 held in the end position by means of a short circuit. By a second edge of the signal generator is no longer applied. The short circuit is canceled and a new signal for actuating the drive can be recorded. With the help of the first edge of the electric drive is now started within the scope of the invention. In contrast, by means of the second edge, a shutdown of the short circuit or a procedure such that the short circuit is set ineffective and a restart of the drive is made possible.
  • 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 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 or works directly on the locking mechanism, for example the locking pawl.
  • 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.
  • a neutral position or its basic position In this neutral position or 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. This may be a feather and in particular serve center / zero spring, which is advantageously integrated in the driven pulley.
  • 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 voltage can be used.
  • a motor vehicle door lock is shown, which is equipped with a locking mechanism not explicitly shown.
  • 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 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 in the Fig. 1 and 2 shown basic position (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 driven against the counter stop 6 stop 5 is also based on Fig. 3 clear.
  • FIG. 3 Here are the top chart of the Fig. 3 the basic position or initial position A and the end position or end position E of the electric drive 1, 2, 3 shown. If the electric drive 1, 2, 3 is no longer in the end position or end position E, respectively, if the associated electric motor 1 does not experience any corresponding action, then one provides in the Fig. 1 and 2 merely indicated spring 7 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 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 is then still the associated time course of a signal S 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.
  • the lever or blocking lever 11 is pivoted about its axis 12 in a clockwise direction, as can be seen in the transition from the Fig. 1 to Fig. 2 recognizes.
  • 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 varies from “0" to "1” as shown in FIG Fig. 3 passes. The released handle 10 causes the signal S from “1" to "0” falls again. This is accompanied by a first edge Fs and a second edge F E in the time course of the signal S over the time t at the Fig. 3 observed. Both the first edge F S and the second edge F E of the signal S generated by the signal generator 8 are now evaluated in the context of the invention, specifically for driving the electric drive 1, 2, 3. For the evaluation, the control unit 9 provides in the example ,
  • the overall design is such that the electric drive 1, 2, 3 is started by means of the first edge F S of the signal S of the signal generator 8.
  • the first edge F S corresponds to the fact that the electric drive 1, 2, 3 passes from its basic position A into the end position E or experiences a corresponding energization on the part of the control unit 9.
  • the second edge F E of the signal S of the signal generator 8 ensures that the electric drive 1, 2, 3 is switched off. Based on Fig. 3 recognizes that logically the second edge F E coincides with the transition of the electric drive 1, 2, 3 of the end position E again to the basic position A.
  • the energization of the electric drive 1, 2, 3 while taking its end position E, ie when abutment of the stop 5 of the driven pulley 3 on the housing-fixed counter-stop 6 is divided into two phases, namely a starting phase P S and a holding phase P H.
  • the electric drive 1, 2, 3 experiences an active energization with the aid of the control unit 9 in that the control unit 9 acts on the electric motor 1 accordingly.
  • the holding phase P H corresponds to that of the electric motor in question 1 is short-circuited in the example, unchanged holding forces on the electric drive 1, 2, 3 are constructed such that the force of the spring 7 is overcome and the stopper 5 still at the counter stop 6 is present.
  • the start phase P S corresponds to a predetermined start time ts.
  • This start time t S may belong to a duration of 20 ms to 100 ms in the present example case.
  • the start phase P S or the start time t S is immediately followed by the holding phase P H of the electric drive 1, 2, 3.
  • the holding phase P H corresponds to a holding time t H.
  • the hold time t H immediately follows the start time t S.
  • the electric drive 1, 2, 3 - maintains its position such that the stop 5 bears against the counter stop 6 and consequently the pawl raised with the aid of the driven pulley 3 is kept unchanged in the lifted position.
  • 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 is in Embodiment sure that, for example Albertbestromungen the electric drive 1, 2, 3 can not lead to an unintentional opening of the locking mechanism.
  • the electric drive 1, 2, 3 can run at all and open the locking mechanism. This allows any Fehlbestromlessness catch because they correspond to that the handle 10 is not deflected. If the electric drive 1, 2, 3 are subject to such Fehlbestromung, so the unchanged engaged in blocking lever 11 in such a case reliably ensures that the electric drive 1, 2, 3 is blocked and the impinged by him locking experienced no opening ,
