Definitions

  • Motor vehicle door lock here is generally to be understood as a side door lock, a rear door lock, a tailgate lock, a hood lock or the like of a motor vehicle.
  • a first known motor vehicle locking device (DE 197 43 129 A1)
  • position detection of a movable actuating element is provided.
  • a reference point sensor is provided so that a reference point or zero point adjustment can be carried out repeatedly.
  • the aforementioned reference point adjustment has the disadvantage that the actuating element can pass through undesired adjustment positions when moving into the reference position, so that, for example, an undesired unlocking or locking of the motor vehicle locking device takes place during the reference point adjustment can.
  • a further disadvantage is that the motor vehicle locking device cannot be used during the reference point adjustment.
  • DE 296 18 688 U1 discloses a device for querying the switching positions of a locking cylinder of a motor vehicle door lock.
  • the lock cylinder is coaxially connected to a switching nut which is provided with a magnet.
  • the Hall socket is assigned to two Hall sensor chips, the Hall sensor chips preferably querying different signals, for example the "locking" and “unlocking" positions on the one hand and the "theft protection” position on the other hand.
  • a coding of different control positions for the unambiguous detection of the control positions is not disclosed.
  • each pole zone has a certain extension in the direction of movement or adjustment, which is not to be neglected in practice, that is, along the path of movement of the actuating element. It is therefore often desirable, especially when using an electromotive actuator which is controlled as a function of the detection of actuating positions, but which has a certain lag, to already detect the limit or the beginning of an actuating position to be detected or an actuating position range to be detected ,
  • the path of movement is to be understood as an essentially linear sequence of points on the actuating element which pass a fixed point when the actuating element is moving.
  • the arrangement of position elements along a movement path on the control element enables the position elements to be detected one after the other - depending on the position or position of the control element - by a stationary sensor assigned to the control element or this movement path.
  • a switching or digitally operating sensor is to be understood here quite generally as an electrical or electronic component with possibly associated evaluation electronics, so that a discrete, preferably only two switching states, status signal is provided.
  • three switching states such as the north pole, south pole or no magnetic pole nearby, can also be provided as an output signal by the sensor.
  • it is preferably a digital output signal that is output by the individual sensor as a function of the proximity or adjacent position of a position element.
  • a clear detection of a setting position is to be understood here so that the different positions to be detected can be distinguished without reference to a reference point or a reference position of the setting element, that is to say in particular the position of the setting element is absolutely fixed in the case of a detected setting position.
  • a displacement mechanism in particular one that can be adjusted indirectly or directly, especially by an electromotive actuator, pivotable and / or rotatable - to understand element that can assume various positions that specify certain positions of at least one component, such as a locking lever of the lock mechanism, a pawl, also a rotary latch or another actuating element of the motor vehicle door lock.
  • the actuating element can thus, for example, represent an adjustable component, be formed thereon, or be connected or coupled to a component which can be adjusted by means of an actuator. Accordingly, the actuating element itself can actuate another component or be adjusted by another component.
  • a very easy to implement, universally applicable embodiment provides a disk-like design of the actuating element, the position elements being arranged along coaxial movement paths or tracks on a flat side of the actuating element.
  • the flat side of the actuating element can be magnetized in some areas in order to form magnetic areas as position elements.
  • Contactless detection is preferably provided by means of correspondingly contactless sensors. This enables a wear-free construction. Alternatively, however, mechanically operating switches or the like can also be used as sensors.
  • an electric actuator or drive motor can have a Act spindle or screw on an adjusting element 1 which in this case is provided with a corresponding external toothing.
  • an adjusting element 1 which in this case is provided with a corresponding external toothing.
  • the actuating element 1 is not limited to a rotary movement or twisting, but depending on the construction, linear and / or superimposed adjustment movements are also possible.
  • the actuating element 1 then acts, for example, on a lever or cam or the like, not shown, on a lever or other actuating element of the motor vehicle door lock.
  • actuating element 1 then acts, for example, on a lever or cam or the like, not shown, on a lever or other actuating element of the motor vehicle door lock.
  • solutions other than those shown in DE 197 43 129 A1 are possible.
  • Each sensor 3 is assigned to a movement path of the actuating element 1 in order to recognize or detect position elements 2, which are moved past or approximated to the sensor 3 when the actuating element 1 is moved or adjusted accordingly.
  • the intermediate areas 4 are coded uniformly or in the same way. In the example shown, no position elements 2 are arranged or formed in the intermediate areas 4.
  • the uniform coding of the intermediate areas 4 enables the number of required movement paths along which the position elements 2 are arranged and accordingly the number of required sensors 3 to be minimized for a predetermined number of position positions A to E to be detected.
  • the illustration on the left illustrates the different coding of the setting position areas A to E and the intermediate areas 4 or the output signals output by the sensors 3 when the setting element 1 is adjusted or rotated in the direction of the arrow 5.
  • the actuator can be switched off.
  • the wake of the actuator then has the effect that the actuating element 1 moves a little further to the center of the desired actuating position range A to E.
  • the desired positioning position range A to E is thus reached without a clear detection or identification of the limits of the positioning position range A to E.
  • the adjustment or movement direction of the setting element 1 is preferably evaluated as additional information in the position detection. This can be achieved in a very simple manner by taking the direction of energization of the electromotive actuator into account in the position detection.
  • the previously detected positioning position range A to E can be taken into account as additional information in order to enable a clear detection of the limits.
  • the position detection can be checked for plausibility.
  • the three sensors 3 can uniquely detect up to seven adjustment position ranges with binary coding. If two sensors 3 are used, a detection of up to three setting position ranges is possible.
  • the position elements 2 on the adjustable control element 1 and the associated sensors 3 are arranged in a fixed position. Of course, this can also be done in reverse.
  • At least the part of the actuating element 1 which carries the position elements 2 is preferably formed in one piece. This enables a simple and compact structure. When this part is initially produced separately, a connection then takes place, for example by gluing, screwing, clamping or the like. Accordingly, the part carrying the position elements 2 can be attached to a control element 1 of virtually any design, for example essentially consisting of metal.
  • control element 1 is disc-like. However, it could also be lever-like or rod-like, for example.
  • binary coding is provided.
  • a different coding for example based on the triple system, for which the detection of different magnetic polarities and no magnetic pole is particularly suitable, can also be provided. If necessary, the number of required sensors 3 can be further minimized.
  • the proposed position detection was explained above using a preferred embodiment of a motor vehicle door lock.
  • the position detection described above can also be used for other position detections, in particular for actuators in motor vehicles. It is essential that the number of sensors required is minimized, particularly when there are several positioning positions or positioning position ranges to be detected.
