Definitions

  • the present invention relates to a motor vehicle door locking device according to the preamble of claim 1 and a method for detection of a closed state of a motor vehicle door locking device according to the preamble of claim 18.
  • the use of a mechanical switch to detect the closed Condition is disadvantageous. Because relatively large tolerances in the closed Condition with regard to the relative position of the lock and striker or locking block can occur, in particular by one with the Frame of non-aligned motor vehicle door and in particular in the longitudinal direction of the motor vehicle, namely, is a complex structure of the mechanical Switch required. This is associated with corresponding costs. In addition, the tolerances mentioned can lead to very different loads of the mechanical switch so that the desired service life is at best difficult to reach. The aforementioned, known structure also has multiple moving parts, making it more vulnerable and leads to relatively high costs.
  • DE-PS 2 060 060 known motor vehicle door lock afflicted.
  • a locking block a striker in which a mechanical switching device is integrated.
  • the invention has for its object a motor vehicle door locking device and a closed state detection method specify a motor vehicle door locking device in which one reliable detection that is largely insensitive to positional tolerances the closed state with preferably a relatively small Effort is made possible.
  • the senor has a force or pressure sensitive sensor element on the locking block for detecting the closed state of the motor vehicle door locking device is arranged. So the sensor works as a pressure sensor, which detects pressure on the locking block. This can be done proportionately realize and allow little effort in a simple manner reliable detection of the closed state of the motor vehicle door locking device.
  • closure here is in particular the provision of data or measurement signals meant, whose evaluation enables detection or sensing, whether the door closing device is closed, i.e. the closed state is present.
  • the evaluation can in particular be carried out directly in a Electronics assigned or arranged therein and / or in a sensor separate evaluation electronics or the like. This is a matter of course for the person skilled in the art, so that this is not discussed in more detail is, since it does not primarily matter where the evaluation takes place. However it is advantageous if the corresponding detection signal for Providing evaluation electronics already at least partially in the Closing block is integrated.
  • pressure and "pressure load” are used in the present patent application to be understood in a broad sense, so that also a grasping or measuring a force in general and a load on one Pressure or tensile force are included. In particular, it doesn't come primarily on the fact that a pressure in the sense of force per area is measured or is detected. However, based on the measured absolute or relative Pressure and / or the measured absolute or relative force as the only one or additional information can be decided whether the closed state is present.
  • Form- or pressure-sensitive sensor element is in the present patent application no mechanically operated electrical switch to understand. Rather, this is to be understood as a measuring element or a measuring device, the or which preferably provides electrical measurement signals to the Correlate force or pressure, in particular largely depend on it, that of the lock on the lock block, in particular is exerted on the sensor or a part of the sensor.
  • the at least one sensor element in the aforementioned Senses and includes, for example, an associated contact element or the like. can already evaluate or further process the measurement signals of the sensor element, that the sensor only outputs a detection signal which indicates the presence of the closed state.
  • a fixed part of the lock acts, in particular a part of a carrier plate or a safety bearing used therein, in the closed state of the motor vehicle door locking device the sensor. This already minimizes the possible tolerances of the location of the Sensor relative to the part of the lock acting on it.
  • the senor can also be equipped with a movable one or movably mounted part of the lock, such as a rotary latch, interact or in contact when closed.
  • a movable one or movably mounted part of the lock such as a rotary latch
  • the sensor element or at least one is preferably the sensor element associated contact element of the sensor, which is closed with the lock State comes into contact, at least essentially in the rear Area related to the closing movement that the locking block relative to Castle executes, arranged.
  • This enables a simple, compact Structure of the locking block, with the sensor in a largely reset Area is arranged, which in particular the locking bolt the sensor from damage when the motor vehicle door locking device is open or motor vehicle door protects.
  • the medium leads moreover to an advantageous averaging with, for example, only one-sided or local loading or deformation of the contact element by the lock, for example with tolerances in the relative alignment of the lock and Locking block in the closed state, which optimizes detection of the closed state is made possible.
  • the above solution is So highly insensitive to the tolerances mentioned at the beginning.
  • the contact element is also elastic deformable, but not with a cavity for a medium provided in the aforementioned sense.
  • the sensor element assigned to the contact element such that there are deformations of the contact element and / or can detect forces exerted on the contact element.
  • the sensor element is, for example, in the form of a strain gauge or as their capacity or other electrical parameter changing conductor arrangement arranged on the contact element or with this connected.
  • a piezo element can be used as the sensor element be provided, which is connected to the contact element, in particular this carries so that exerted by the lock on the contact element Forces, in particular pressure loads, detected by the piezo element and can be evaluated for the presence of the closed state.
  • the sensor element can also be integrated in the contact element, poured, for example.
  • the contact element is then preferred movably mounted, so that the contact part at least partially can dodge if the lock on the contact part when closing the Motor vehicle door locking device hits.
  • the lock works on both sides an insertion slot for the locking bolt, a backup bearing for the Locking bolt or one arranged on the insertion slot or catch bearing Collar on the contact element in the closed state.
  • These two Pages are usually in a vertical plane, so that even in proportion strong vertical offset of the locking block and lock compared to the Sollage acts on the contact element at least one side such that the Sensor element can detect the closed state.
  • contact element compensation in terms the change or rate of change in the pressure of the medium when closing the motor vehicle door locking device, so that a quasi unchanged evaluation can take place, especially with regard to a vertical offset is insensitive.
  • the contact element can also be displaced accordingly in particular across the longitudinal axis of the locking bolt and across the closing direction the motor vehicle door locking device slidably, stored or be trained.
  • a procedural development provides that in the detection of closed state additionally one provided by the lock Closing the lock signal indicating the lock mechanism, for example the engagement of the pawl or with the swivel position of the rotary latch correlated lock signal is evaluated.
  • This enables a special reliable detection of whether the motor vehicle door locking device is working properly is closed when the closed state is only detected becomes when both the sensor arranged on the locking block the closed State has detected as well as the lock signal the closed state indicated.
  • the temporal correlation can be taken into account in particular be, that for example that arranged on the locking block Sensor outputs a brief signal when closing and within one predetermined time the corresponding lock signal must be present.
  • FIG. 2 illustrates that in the closed state a holding device, such as a catch 5, the lock 2 Locking bolt 3 of locking bolt 4 secures or holds in lock 2.
  • the sensor element 7 is preferably a contact element 11 assigned to which the lock 2 acts in the closed state.
  • both sides of the inlet slot come in the closed state 8
  • the catch bearing 10 or one of the inlet slot 8 or the Catch bearing 10 associated collar 12 which is usually along the edge of the inlet slot 8 or the catch bearing 10 protrudes for stiffening, in closed state on the contact element 11 to the system.
  • the sensor element 7 or the contact element 11 also with other parts the lock 2, for example the rotary latch 5, cooperate in the closed state, to detect the closed state by the sensor element 7 to enable.
  • FIG. 3 illustrates that the sensor 6 or at least the contact element 11 and in particular the sensor element 7 in a rear area 13 based on the closing movement S, the locking block 4 executes relative to the lock 2 when closing is.
  • This is particularly the case with the preferred interaction of the Sensor element 7 or the contact element 11 with run-in slopes, the Inlet slot 8, the catch bearing 10 or the collar 12, as in FIGS. 2 and 4 indicated, favorable.
  • this arrangement can be extensive Protection of the sensor 6, as can be seen from the illustration in FIG.
  • the locking block 4 for example, one on the not shown Has door post base plate 14 to be fastened, of which the locking bolt 3 and a leg 15 protrude in the rear region 13, the Leg 15 in a base plate 14 at least substantially parallel extending counterplate 16 passes over, so that the locking pin 3 between the base plate 14 and the counter plate 16 is kept stable.
  • the sensor 6 or the contact element 11 is essentially of Sections of the base plate 14 and the counter plate 16 and the leg 15 surrounded and thus from damage, especially when open Motor vehicle door locking device 1 protected.
  • Fig. 3 shows only one embodiment of the locking block 4, which here essentially U-shaped with locking bolt 3 in between is.
  • the contact element 11 is designed to be elastically deformable.
  • the contact element 11 has a cavity 17 which is filled with a gaseous and / or liquid medium 18 and with the associated sensor element 7 is connected in such a way that the sensor element 7 the pressure or pressure changes of the medium 18 in the cavity and / or can detect a flow of the medium 18 in the cavity 17.
  • the absolute and / or relative pressure of the medium 18 for the detection of the closed state be used.
  • the aforementioned sensing by means of the medium 18 enables optimal Training and adaptation of the contact element 11 to the particular installation situation and the associated lock 2, since the outer contour of the contact element 11 can be chosen almost completely freely.
  • Fig. 4 shows a second embodiment of the sensor 6.
  • the contact element 11 is also elastically deformable, but in particular without closed cavity 17, but for example as a solid body.
  • the contact element 11 is here preferably with a piezo element 19 or the like. Connected as a sensor element.
  • the piezo element 19 detects the contact element 11 in the closed state exerted pressure loads or forces, so that in turn a detection of the closed state is possible.
