Definitions

  • the invention relates to a locking device, in particular for a door or the like of a vehicle, according to the features of the preamble of Claim 1.
  • a locking device is known from DE 197 39 340.3, which in particular for a door, a trunk lid or a tailgate or the like a vehicle is used.
  • An actuator is provided here its movement via a transmission element to an element of the locking device transmits, depending on the movement of the actuator different Functional positions of the locking device, such as anti-theft position, Central locking position, etc. can be set.
  • the DE 197 39 340.3 is the operative connection of the actuator via the transmission element described on the element of the locking device; there are this patent application, however, no information regarding the control and the position detection of the actuator or the transmission element refer to.
  • the object of the invention is therefore to provide a locking device, which, in addition to the implementation of the functional positions, also the control of the actuator and the implementation of the control.
  • means are therefore provided for the continuous movement as well as the functional positions (if necessary also reaching the Functional positions) of the actuator or the transmission element to capture.
  • This ensures that the actuator from one Function position controlled to achieve a further function position is what the continuous movement as well as reaching a following functional position is detected in order to then control the actuator in such a way that the following, desired functional position is reached and maintained becomes.
  • a starting position can be the anti-theft position, for example be taken after the vehicle is parked and secured has been. If you now want to drive the vehicle, you must the locking device by controlling the actuator from the anti-theft position to bring into the central unlocking position, so that the Side door can be opened from the outside.
  • the actuator can also are controlled so that one functional position or several functional positions to be skipped.
  • the detection of the continuous movement also has the advantage that a statement about it is possible at any time is in which functional position and also in which position in between the actuator or the transmission element is around to be able to carry out a plausibility check based on the detected position.
  • the means comprise a potentiometer
  • the one connected to the actuator or the transmission element grinder has, depending on the movement of the actuator or the transmission element travels over a resistance track, the potentiometer is electrically connected such that it is a continuous Signal representing motion generated.
  • a potentiometer enables the acquisition of the continuous in a simple manner Movement, such a potentiometer being largely linear Output signal, so that in every functional position or in every Intermediate position signals are present that are used for position detection or can also be used for a plausibility check can.
  • the means have a switching device that one connected to the actuator or the transmission element Has grinder, depending on the movement of the actuator or the transmission element travels over several contact surfaces, wherein the switching device is electrically connected such that it has a signal if there is a functional position (or a functional position area) gives the locking device. While it is provided here that if there is a functional position of the locking device, a signal is delivered and no in the positions between the functional positions The opposite procedure is also conceivable. The means that if there is a functional position, there is no position and an intermediate position a signal is given. Due to the output signal of the Switching device can thus be reliably recognized when after activation the actuator has reached a functional position, then the To interrupt actuation of the actuator.
  • the combination of the output signal of the potentiometer is particularly advantageous with the output signal of the switching device, so that at any time, while the actuator is activated or in a functional position a statement is possible in which area the Actuator or the transmission element is located (due to the Evaluation of the output signal of the switching device) and whether a movement of the actuator or the transmission element during activation is present or not (based on the evaluation of the output signal of the potentiometer). Is there a signal for activation and changed the output signal of the potentiometer does not change, causing either that Output signal itself or its change in time is evaluated on to close a defect, for example in an electrical interruption the control or jamming of the element of Locking device can have its cause. Furthermore it is possible due to the at least two separately evaluable output signals perform a plausibility check, depending on Predeterminable quantities (for example deviations) an emergency operation is carried out can be.
  • the signal from the potentiometer for superimposed control of the actuator can be evaluated if it is reached after the actuation of the actuator a functional position that is about to be reached. This means, that driven from a first functional position of the actuator to achieve the following functional position. This is done, for example with a signal that causes the actuator to rotate.
  • the potentiometer evaluate to recognize the achievement of a functional position if the output signal of the potentiometer is in predetermined value ranges.
  • the control signal can for the actuator can be reduced, for example, the speed to reduce the actuator; if then by means of the switching device has been recognized that the desired functional position has been reached can the control signal for the actuator can be further reduced or switched off, which also overshoots and a resulting repositioning or new control can be avoided.
  • the potentiometer and the switching device a common grinder is provided, the taps each for the resistance track and carries the contact surfaces, the taps being electrical from one another are separated so that the output signals of the potentiometer and of the switching device do not influence each other.
  • the taps each for the resistance track and carries the contact surfaces, the taps being electrical from one another are separated so that the output signals of the potentiometer and of the switching device do not influence each other.

  • the transmission element has contours Drive pulley for setting the functional positions of the Locking device trained.
  • the design of the contours Drive disc is shown in DE 197 39 340.3.
  • the flat drive disc has the advantage that due to the flat design also an overall very flat design of the Locking device adjusts so that again the inside of the door, the tailgate or the like available space is used optimally becomes.
  • design freedom due to the flat design therefore given that already existing locking devices against the Locking device according to the invention are interchangeable.
  • the actuator and the transmission element arranged in a housing can be used.
  • the circuit board in the Housing can be used.
  • This configuration has the advantage that the circuit board can be omitted, since their function the inside of the housing (in particular one half of the housing).
  • there is no such Design the insertion of the circuit board, thereby the manufacture of the Locking device is reduced by one production step. This offers itself especially when the grinder for the resistance track and / or the contact surfaces are already connected to the transmission element or form a structural unit with it.
  • the circuit board has electrical connections at least for the potentiometer and the switching device and if necessary for the actuator.
  • the Printed circuit board can also carry a plug or the like or record, by means of which the electrical components within the Housing of the locking device can be connected to the outside world. Such a plug or the like is used to connect the Locking device, for example, via a bus or other cables central control unit.
