Definitions

  • the present invention relates to the field of motor vehicle locking systems and relates to a motor vehicle lock according to the preamble of the independent device claim.
  • vehicles sometimes have sensors for detecting the position of locking parts such as pawl and rotary latch. At least one open position and one locking position of the locking mechanism can be detected by means of such sensors or switches, so that it can be determined whether the moving part of a vehicle is locked.
  • a motor vehicle lock with a microswitch for detecting the position of the rotary latch and pawl relative to one another is known.
  • the locking mechanism assigned to the lock works together with an additional contoured lever, which actuates the microswitch and can thus provide information about the position of the rotary latch and pawl in relation to one another.
  • a motor vehicle lock which has an inductive sensor for detecting the position of the pawl and an additional inductive sensor for detecting the position of the rotary latch.
  • a disadvantage of the known prior art is that a plurality of sensors and/or additional levers are required to detect the position of the rotary latch and the pawl in order to detect the position.
  • the use of a plurality of sensors and/or additional levers increases the costs and structural complexity of the motor vehicle lock.
  • the present invention is therefore based on the technical task of providing at least one motor vehicle lock, the disadvantages of the prior art being at least reduced.
  • a motor vehicle lock for a movable part of a vehicle, in particular a door, flap, tailgate, seat, charging plug lock, hood or sliding door.
  • the motor vehicle lock has a locking mechanism consisting of at least one pawl and a rotary latch and a sensor arrangement assigned to the locking mechanism.
  • the sensor arrangement comprises a stationary sensor and at least one button element arranged on the rotary latch, the sensor generating at least two different signals relating to the presence and absence of the button element in the area of influence of the sensor.
  • At least one second button element is provided, with the second button element being arranged on the pawl and with the first and the second button element being able to be detected, in particular together, by the stationary sensor and thus different positions of the locking mechanism, in particular of the rotary latch and the pawl, being detectable.
  • An essential advantage of the motor vehicle lock according to the invention is that several positions of the locking mechanism, in particular the rotary latch and the at least one pawl, can be monitored and recognized. A precise statement about the exact position of the locking mechanism components can thus be obtained.
  • the sensor arrangement according to the invention can be used in a particularly advantageous manner for a closing aid of a motor vehicle lock, making it reliable in the event of pinching can be recognized.
  • the positions are a pre-locking position, a main locking position and at least one open position of the locking mechanism.
  • a plurality of sensing elements are arranged on the at least one rotary latch and/or the at least one pawl.
  • Motor vehicle locks can have multiple locking positions.
  • a motor vehicle lock according to the invention can have at least one pre-locking position and a main locking position as well as an open/unlocked position.
  • generic motor vehicle locks can have at least one lock housing, a lock cover and a lock case (hereinafter subsumed under the term lock housing), the locking mechanism thus being essentially enclosed/closed by the lock housing. Due to the configuration of the sensor arrangement according to the invention, in particular the stationary sensor, preferably in the lock housing, and the arrangement of the at least two sensing elements, at least the locking positions described above can be detected.
  • the feeler element preferably works in a non-contact manner on the sensor. In addition, however, a tactile interaction can also be provided in addition or as an alternative.
  • a control unit having at least one computing unit for processing signals or data, at least one memory unit for storing signals or data, at least one interface to a sensor or an actuator for reading in sensor signals from the sensor or for outputting data - Have or control signals to the actuator and / or at least one communication interface for reading or outputting data that are embedded in a communication protocol.
  • the arithmetic unit can be, for example, a signal processor, a microcontroller or the like, with the memory unit being able to be a flash memory, an EEPROM or a magnetic memory unit.
  • the communication interface can be designed to read in or output data in a wireless and/or wired manner, with a communication interface reading in or outputting wired data can, for example, read this data electrically or optically from a corresponding data transmission line or can output it in a corresponding data transmission line.
  • the control unit can be designed to execute a diagnostic routine. This makes it possible to check whether the sensor arrangement/the sensor is in an operational state or whether there are malfunctions. Depending on a diagnostic routine, it is possible to recalibrate the system if necessary, readjust system parameters or display any errors so that maintenance is possible. So it is conceivable that the associated target measured values of a predetermined/defined position, for example main position, are stored and compared with actual measured values, so that deviations can be detected and conclusions can be drawn about possible malfunctions. During the product life cycle, changes, caused in particular by wear and tear or external environmental influences, can be recognized and included in the position determination. The reliability of the position detection is thus increased.
  • the motor vehicle lock according to the invention can advantageously have a lock drive, in particular a closing drive.
  • the lock drive can be directly or indirectly operatively connected to the locking pawl and/or the rotary latch for locking and/or unlocking the locking mechanism. Lifting or inserting the pawl in first position or main position is conceivable.
  • a closing drive preferably interacts with the rotary latch and can move/drive it at least from an open position to the first position, from the first position to the main position or from the main position to an overtravel position.
  • the closing drive can act directly or indirectly on the rotary latch.
  • the control unit evaluates signals from the sensor to control a lock drive, in particular a closing drive.
  • a lock drive in particular a closing drive.
  • the intermediate position between the pre-locked position and the main locked position may be detected.
  • the intermediate position corresponds to a gap between a motor vehicle door, motor vehicle flap or motor vehicle hood belonging to the motor vehicle lock being so small that pinching can no longer occur.
  • the sensor reports that the intermediate position has been reached, but not that the main detent position has been taken immediately afterwards.
  • the sensor arrangement assigned to the locking mechanism can be arranged in the lock housing.
  • the rotary latch of a motor vehicle lock usually has a fork-shaped entry slot formed by the load arm and catch arm, through which the locking bolt of a vehicle door or hatch reaches when the door or hatch is closed.
  • the locking bolt then pivots the rotary latch, which can be latched via the pawl.
  • the locking bolt can then no longer leave the entry slot of the rotary latch.
  • This locking position is also called the main locking position.
  • the locking of the rotary latch and pawl can preferably take place on the load arm of the rotary latch.
  • the load arm has corresponding contours (locking contours) for different locking positions (pre-locking, main locking) at which the pawl contacts the rotary latch and locks.
  • the sensor arrangement can advantageously be arranged in/on the area described above.
  • the stationary sensor can be arranged, for example, in the lock housing in such a way that interaction with the button element on the rotary latch and the button element on the pawl can be achieved. Accordingly, it is conceivable to use the button element in each case in the area of the latching contour of the catch and in the contact area, e.g. B. the locking surface of the pawl to arrange.
  • the latching positions in particular the first latch and the main latch, can be detected particularly reliably by the stationary sensor and the sensing elements on the rotary latch and pawl. The particular rotational movement of the rotary latch and pawl can thus be detected in particular along the radius of movement of the locking parts.
  • Motor vehicle locks can also have so-called electrical component carriers for electrical and/or electronic components. According to the invention, the stationary sensor can be arranged on such electronic component carriers.
  • the electronic component carrier can also be a circuit board or a part of the lock housing.
  • the feeler element is generally arcuate.
  • the curved shape of the scanning element is adapted to a pivoting movement of the locking mechanism component to be scanned. Since the probe element is generally connected to the rotary latch or is or can be a part of the rotary latch, the curved shape is usually equipped with an associated radius, which is measured according to the distance from the axis of rotation of the rotary latch. As a result, the curved shape of the scanning element is adapted to the pivoting movement of the locking component to be scanned, here the rotary latch.
  • motor vehicle lock for a moving part of a motor vehicle, this should at least be understood to mean side door locks, wing doors, swing doors, rear doors, tailgate locks and hood locks or hood locks and charging connector locks. These all fall under the generic term motor vehicle lock.
  • the senor arrangement can act capacitively, inductively, optically or magnetically, i. H. be trained.
  • the probe element can also generate a changing electrical resistance in the sensor.
  • the pushbutton element is, for example, a slide in the case of a linear potentiometer or a rotating adjusting ring in the case of a rotary potentiometer.
  • sensors for detecting pivot angles are also conceivable elsewhere in motor vehicles and are used, for example, to detect a pivot angle of a motor vehicle door, as is the case in DE 10 2011 119 579 A1 the applicant is described in detail.
  • the sensor is therefore designed as a resistance sensor. In this case, again depending on the position of the rotary latch in the example, a largely linear signal from the sensor generated as a function of the rotation angle of the rotary latch, in this case a correspondingly changing electrical resistance.
  • the button element generates a different optical light intensity in the sensor.
  • the sensor is designed as an optoelectronic sensor.
  • the feeler element may be a surface or line with a changing degree of reflection for light falling on it and emitted by the sensor and received by an associated receiver. This means that depending on the angle of rotation of the rotary latch in the example, the button element attached to the rotary latch with a changing degree of reflection ensures that the light intensity received by the optoelectronic sensor after reflection on the button element is changed.
  • the probe element generates a largely linear signal depending on the rotary latch angle depending on the position of the rotary latch in the measuring range of the sensor or optoelectronic sensor. It is possible to work with light in the visible range as well as, for example, in the near infrared range.
  • the sensor arrangement is designed as a Hall sensor (sensor arrangement). It can particularly preferably be linear Hall effect sensors. Hall sensors of this type are particularly suitable for distance measurements or the measurement of rotational movements.
  • linear Hall sensors with a linear output characteristic can preferably be used, which output a signal that is proportional to the magnetic field strength. This can be provided as an analog voltage, a pulse width modulated signal (PWM) or in the SENT protocol.
  • PWM pulse width modulated signal
  • Their output characteristics can be linearized, which means that tolerances in the magnets or the mechanical structure can be fully compensated.
  • the sensors can be diagnosable and designed for precise distance measurements up to 40 mm and angle measurements up to 180 degrees and/or have a redundancy function.
  • two independent sensor chips dual-die
  • 2D direct-angle Hall sensors
  • 2D can be used, which are also able to To measure the alignment of the field:
  • vertical Hall elements detect the component in the chip plane.
  • the internal signal processing uses this to calculate angle (up to 360 degrees) and position information. It can be particularly advantageous if the sensor arrangement, in particular the sensor, is designed to be self-calibrating. Measurement inaccuracies can thus at least be reduced.
  • the first feeler element and/or the second feeler element is designed to be magnetic, in particular as a magnet.
  • the sensor arrangement is designed as a Hall sensor (arrangement).
  • the magnet can be designed as an insert in the rotary latch and the pawl, in particular in a casing of the rotary latch or pawl.
  • a further advantageous embodiment are plastic-bonded magnets, which are formed in particular in the casing of the rotary latch and/or pawl.
  • Plastic-bonded magnets are particle composites in which permanent magnet powders are embedded in plastic binders. Hard ferrite (HF), various SmCo and NdFeB powders and, to a very small extent, AlNiCo alloys are used as magnetic powder.
  • Thermoplastic binders e.g. polyamide (PA) or polyphenylene sulfide (PPS), as well as duroplastics, e.g. epoxy resins, are used to bind the magnetic particles.
  • isotropic and anisotropic magnets can be manufactured with different magnetic and mechanical values. Since not only the type of magnet and plastic material, but also the degree of filling and alignment determine the properties of the composite material, there is a wide range of magnetic parameters and a considerable variety of types and shapes.
  • the magnets can be embodied as magnetic adhesive tape in a particularly cost-effective manner. These can be in the form of tapes with an adhesive layer on one side and can be flexibly shaped.
  • At least one button element is arranged on a switch cam of the pawl and/or the rotary latch.
  • the switching cam can be arranged on a common axis and/or fastened to the rotary latch or pawl or be formed from a casing of the rotary latch or pawl.
  • a switching cam according to the invention can, for example, reduce the distance between the rotary latch/rotary latch body or pawl/pawl body and the pushbutton element. This allows design freedom to be achieved.
  • the switching cam can, for example, be made of plastic, in particular a plastic injection molded part or a 3D printed product and be arranged on the rotary latch, the pawl or the rotary latch axis or pawl axis. If the sensor is now, for example, arranged on an electronic component carrier or at a point on the lock housing which is arranged at such a distance from the pushbutton element that the sensor signals are influenced without switching cams, the switching cam according to the invention can remedy this.
  • the probe element in particular the magnet, can be arranged as an insert on the switch cam or the switch cam is designed at least in sections as a plastic-bonded magnet.
  • the switch cam can advantageously bring about a conversion of the rotational movement of the pawl and/or the rotary latch into a linear movement of the at least one pushbutton element.
  • the variability of the use of space can be improved.
  • the electronic component carrier (EKT) can be designed more simply and the sensor arrangement or the EKT does not have to be constructed or adapted in a cumbersome manner.
  • the feeler elements are each arranged on a side of the pawl and/or the catch that is oriented towards the sensor.
  • the signal quality can thereby be improved, while at the same time the space required can be reduced.
  • the at least one button element of the rotary latch and the at least one button element of the pawl are arranged in the same orientation and oriented towards the sensor, the sensor can detect the position of the locking parts particularly easily and precisely.
  • a side here means, for example, the side/surface of the rotary latch or pawl which is oriented towards the lock plate on which the locking mechanism is mounted or the corresponding side which faces away from the lock plate. This becomes even clearer when viewed together with the figures and the description of the figures.
  • the output signal of the sensor is generated depending on the angle of rotation of the rotary latch and/or the angle of rotation of the pawl.
  • the output voltage of the sensor can be changed depending on the angle of rotation of the rotary latch and/or the angle of rotation of the pawl.
  • the control unit can process the output signal of the sensor and thus deduce the position of the pawl and rotary latch.
  • the sensor particularly preferably supplies different output voltages as output signals, which are generated as a function of the rotation angle of the rotary latch or pawl. The output voltage thus provides conclusions about the position of the pawl and rotary latch, with many different positions being able to be detected.
  • the change in the output voltage thus enables a number of position signals, in particular exact position signals that change with the movement.
  • a large number of different output voltages are thus generated, which provide an indication of the position.
  • the evaluation of the output signals can then be processed by the control unit and used to control and/or regulate, for example, door drives, closing aids or opening drives.
  • the direction of movement/rotation of the locking parts can also be determined. Accordingly, a transition of the positions or the direction can also be determined. i.e. it is possible to use the output signals to determine whether, for example, unlocking (from the main position to the open position) or locking (from the open position to the first position or main position) is being carried out. Consequently, not only an exact determination of the position of the locking mechanism but also an opening or closing process can be detected.
  • At least one feeler element can essentially have a geometry that changes over its course.
  • the probe element can have a width or thickness that changes in its longitudinal extent. This can be used to influence the signal size/strength in the sensor's area of influence, so that the signals provide precise information about the positions. Is the Partial area of the probe element is largest, for example in the area of the first position or the main position, so the signal size/strength can be best/largest as a result.
  • the sensor signal is greatest when the button element of the rotary latch and the button element of the pawl are simultaneously positioned in the area of influence of the sensor.
  • This can particularly preferably correspond to the main locking position. Accordingly, in the main locking position, both the button element of the pawl and the button element of the rotary latch are arranged in the area of influence of the sensor.
  • the sensing elements can be arranged completely or only in sections in the area of influence of the sensor. It is therefore conceivable that the output voltage of the sensor is greatest when both scanning elements are located in the sensor's sphere of influence. This preferably corresponds to the main latching position, so that the output voltage of the sensor is greatest in the main latching position.

The width or thickness of the feeler element 5 could be greater in the area of the main locking contour 4.4 than in the area of the pre-locking contour 4.3.
