Definitions
- the present invention relates to a motor vehicle door lock according to the Preamble of claim 1.
- Under motor vehicle door lock there is generally a side door lock, a rear door lock, a tailgate lock, a hood lock or the like of a motor vehicle to understand.
- 43 129 A1 is a motor vehicle locking device with position detection a movable actuator known.
- the actuator is disc-shaped and in an electromotive actuator different positions can be rotated.
- On the actuator are along one Movement balm of the positioning element, preferably in the form of magnetic sections or pole zones, so that by means of a assigned sensor, which counts the signals of the position elements, a detection the position of the actuator.
- the disadvantage is with the aforementioned reference point adjustment connected that the actuator undesired positions when moving in the reference position, so that during the reference point adjustment for example, unwanted unlocking or locking the motor vehicle locking device can take place.
- Another disadvantage is that the motor vehicle locking device during the reference point adjustment is not usable.
- DE 296 18 688 U1 discloses a device for querying switch positions a lock cylinder of a motor vehicle door lock.
- the Lock cylinder is coaxially connected to a switching nut, which is connected to a magnet is provided.
- Two Hall sensor chips are assigned to the switching nut, the Hall sensor chips preferably polling different signals, for example on the one hand the positions "locking" and “unlocking” and on the other hand the position "theft protection".
- a coding of different Positioning positions for clear detection of the positioning positions is not revealed.
- the present invention has for its object a motor vehicle door lock specify that in a simple, inexpensive way absolute or unambiguous detection of different positions or Position ranges of an actuator of the motor vehicle door lock enables, only switching or digitally working sensors required are and in particular the number of sensors required is minimized can be.
- a basic aspect of the present invention is several To arrange position elements along offset movement paths on the actuating element, in such a way that each position to be detected is unique is coded so that the positioning positions are assigned by means of the movement paths preferably switching or digitally working sensors clearly are detectable. A first minimization of the Number of sensors required.
- a switching or digitally working sensor is very general here an electrical or electronic component with possibly associated evaluation electronics to understand, so that a discrete, preferably only two switching states comprehensive status signal is provided.
- a discrete, preferably only two switching states comprehensive status signal is provided.
- three switching states such as the north pole, south pole or no magnetic Pole nearby, as an output signal provided by the sensor become.
- it is preferably a digital output signal, that of the individual sensor depending on the proximity or neighboring Position of a position element is output.
- a clear detection of a position is to be understood here so that the different positions to be detected without reference to one Reference point or a reference position of the control element can be distinguished, in particular the position of the control element when a control position is detected is absolutely set.
- an electromotive Actuator directly or indirectly adjustable - in particular to understand sliding, pivoting and / or rotating element that can take up different positions, the certain positions of at least one component, such as a locking lever Lock mechanism, a pawl, also a rotary latch or another Specify the actuator of the motor vehicle door lock.
- the actuator can thus represent an adjustable component, for example, formed on it or connected to a component adjustable by means of an actuator or be coupled. Accordingly, the control element itself can be different Actuate component or be adjusted by another component.
- a very easy to implement, universally applicable design sees a disk-like design of the actuator, the position elements along coaxial trajectories or tracks on a flat side of the control element are arranged.
- the flat side of the control element can be magnetized in some areas in order to be magnetic areas Form position elements.
- a non-contact detection is preferably by means of a correspondingly non-contact working sensors provided. This enables wear-free Construction. Alternatively, however, mechanically operating switches can also be used o. Like. Are used as sensors.
- each pole zone has a specific one, in practice not negligible expansion in the direction of movement or adjustment, thus along the movement path of the control element. Therefore, it is often especially when using an electromotive actuator, which is controlled depending on the detection of positioning positions and has a certain lag, desirable, already the limit or the beginning of a position to be detected or one to be detected Detect position range.
- an electromotive actuator which is controlled depending on the detection of positioning positions and has a certain lag, desirable, already the limit or the beginning of a position to be detected or one to be detected Detect position range.
- This is in a preferred embodiment provided that intermediate areas between to be detected Position positions are coded uniformly, especially in these intermediate areas no position elements are arranged. In this way with a minimal number of switching or digital sensors a detection of the limits of the position ranges and one each enables at least clear assignment to a position range.
- each limit of the position range with a minimal number of sensors, for example with three sensors with five positions, if possible as additional information the direction of movement or current direction of the actuator and / or a previously detected, adjacent position range is taken into account becomes.
- Motor vehicle door lock is referred to, for example, DE 197 43 129 A1.
- an electric actuator or drive motor via a spindle or screw on a in this case with a corresponding Act on the external toothing of the control element 1.
- the actuating element 1 not to a rotational movement or twisting limited, but depending on the construction are also linear and / or overlaid adjustment movements possible.
- the control element 1 then acts, for example, via a not shown Driving pins, cams or the like on a lever or other actuating element of the motor vehicle door lock.
- Driving pins, cams or the like acts, for example, via a not shown Driving pins, cams or the like on a lever or other actuating element of the motor vehicle door lock.
- a position detection device is assigned to the control element 1. This includes positioning elements 2 arranged on the actuating element 1, which here are formed by magnetic areas on the control element 1, and the position elements 2 assigned sensors 3, indicated only as points.
- the sensors 3 can be configured as already defined on the input side.
- the sensors are sensitive to magnetic fields, for example Hall sensors, reed contacts or magnetoresistive sensors.
- magnetic fields for example Hall sensors, reed contacts or magnetoresistive sensors.
- optically working sensors depending on the training the position elements 2 to be recognized.
- Each sensor 3 is assigned to a movement path of the actuating element 1 To recognize or detect position elements 2, which with corresponding Movement or adjustment of the control element 1 moves past the sensor 3 or be approximated to this.
- the position elements 2 are in this way along the movement paths on the actuating element 1 arranged or designed that each position to be detected clearly coded. Because of their direction of movement or adjustment of the control element 1 extending extension of the position elements 2 form or define these different, here five position ranges A to E.
- the position ranges A to E are each different from each other spaced in the adjustment or circumferential direction on the actuating element 1 or formed so that between adjacent positions A until E intermediate areas 4 are formed.
- the position elements 2 are here thus spaced in the direction of adjustment of the actuator 1.
- One aspect of the present invention is that the intermediate areas 4 are coded uniformly or identically. In the example shown in no intermediate elements 2 are arranged or formed between the intermediate regions 4.
- the uniform coding of the intermediate areas 4 enables a predetermined one Number of positioning positions A to E to be detected minimizing the number of trajectories required along of which the position elements 2 are arranged, and accordingly the Number of sensors required 3.
- the illustration on the left illustrates the different Coding of the positioning positions A to E and the intermediate areas 4 or the output signals output by the sensors 3 when adjusted or rotation of the control element 1 in the direction of arrow 5.
- the actuator can be switched off.
- the Overrun of the actuator then acts that the actuator 1 is still a little moved to the center of the desired position range A to E. So the desired setting position range A to E is reached without that a clear detection or identification of the limits of the position ranges A to E takes place.
- Position position range A to E are taken into account to provide a clear To enable detection of the limits.
- a check of the position detection can be used as additional information done on plausibility.
- the three sensors 3 can have up to seven setting position ranges detect clearly with binary coding. In case of use of two sensors 3 is a detection of up to three positions possible.
- the control element 1 preferably has a regionally magnetizable Plastic structure.
- a regionally magnetizable Plastic structure there are a variety of implementation options here. For this purpose, in addition to the disclosure of DE 197 43 129 A1.
- optical or optoelectronic scanning is also possible with appropriate training of the sensors 3 and the position elements 2 possible.
- about the preferred, contactless position detection mechanical detection is also possible, for example, as Cam-formed position elements 2, the mechanical switch o. Like. Act as sensors 3, possible.
- the position elements 2 are on the adjustable Control element 1 and the associated sensors 3 arranged in a stationary manner. Of course this can also be done in reverse.
- At least the one carrying the position elements 2 is Part of the actuator 1 is preferably formed in one piece. This makes possible a simple and compact structure. When initially manufactured separately this part is then connected, for example by gluing, Screws, clamps or the like. Accordingly, the position elements 2 supporting part to a quasi arbitrarily designed, for example in be essentially made of metal actuator 1 attached.
- control element 1 is disc-like. It However, could also be lever-like or rod-like, for example his.
- the position elements 2 are essentially in one Level and arranged along concentric trajectories.
- Each after formation and direction of adjustment or movement of the actuating element 1 can the position elements 2, for example, along straight lines Trajectories and / or in different levels, for example on a cylindrical surface along axially offset circumferential lines, be arranged or formed.
- binary coding is provided.
- the sensors 3 can also be different Coding, for example based on the triple system, for what especially the detection of different magnetic polarities and no magnetic pole is suitable. If necessary, so the number of required sensors 3 is further minimized.
- the proposed position detection was based on a preferred embodiment of a motor vehicle door lock explained.
- the position detection described above can also with other position recordings, especially with actuators in Motor vehicles, find use. It is essential that with several positioning positions or positioning position ranges to be detected Minimizing the number of sensors required is made possible.
