Definitions

  • the invention is directed to a device of the type specified in the preamble of claim 1.
  • a preferred area of application for this device is electronic steering lock in motor vehicles.
  • the invention is also directed, in general, to devices for detecting the position of a movable member in a lock, and would therefore also be readily applicable to an electronic ignition switch where it is important to control one or more key rotary positions. In the present case, the invention will be explained in more detail using the steering lock.
  • microswitches were used to detect the position of the locking pin of a steering lock in order to monitor the locking position on the one hand and the unlocking position of the locking pin with respect to the steering spindle in a motor vehicle on the other hand.
  • two digitally effective Hall sensors are used, which interact with a permanent magnet, which is moved between the two positions when the locking bolt is adjusted. When the movable permanent magnet approaches a certain small distance, the digitally effective Hall sensor switches over and reports the corresponding end position of the locking bolt to an evaluator
  • the locking pin can jam, for example, in one of its end positions, one or both Hall sensors can become defective, or the permanent magnet can change its position.
  • so-called “redundancy” will be sought, where the one to be monitored End position is monitored in two ways.
  • a second permanent magnet and / or further Hall sensors had to be used, which increased the construction effort and / or the space requirement
  • the invention has for its object to develop an inexpensive, space-saving device of the type specified in the preamble of claim 1, which is characterized by high security in the position detection of the movable member. This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following special meaning.
  • the second Hall sensor for example, for monitoring the locking position, has the additional function Given also to monitor the unlocking position of the locking bolt. This is done by using the invention with the second Hall sensor instead of the digital one, because in this way the response range of this second Hall sensor extends over a large distance.
  • this second analog Hall sensor can inform the evaluator of the time course of the signals, at least in that section of the path of movement of the permanent magnet where the the first end position of the locking bolt, which is already monitored by the first Hall sensor.
  • the second analog Hall sensor is therefore redundant to the first Hall sensor. From the time course of the signals, the evaluator can differentiate between the various possible malfunctions and thereby trigger the specific function in the vehicle. This includes, for example, repeating the locking pin movement, or a corresponding fault message to the master electronics, or an error message, or an alarm trigger, or a shutdown of engine operation in the motor vehicle
  • Fig. 3 is a development of a part-circular curved stroke curve for the locking bolt of this device with indicated response range of the two Hall sensors and
  • FIG. 4 shows the signals from the two Hall sensors of this device to the evaluator when the locking bolt is lifted between its two end positions
  • the device according to the invention is shown in the drawings as an electronic steering lock 10, which in turn can be part of a vehicle authorization system.
  • This device will be referred to as "ELV" for short.
  • the ELV 10 is an integrated solution consisting of mechanics, electrics and actuators, which is basically the one from FIGS 2 apparent structure
  • a locking pin 11 is to be moved between two positions 11, 11 ', which are drawn out or shown in dash-dot lines in FIG. 2.
  • the locking pin In the position 11 drawn in a solid line, the locking pin is in its locking position, which can be seen in FIG
  • the steering column 12 of the vehicle is blocked, so that rotation of the steering column 12 in the direction of arrow 13 is not possible.
  • the locking bolt In the position shown in dash-dotted lines 1 1 ', the locking bolt is in its unlocking position. Then the locking bolt 11' is out of the locking opening 14 of the column 12 can be pulled out and the aforementioned steering column rotation 13 is possible
  • the locking pin 11 is structurally connected to a lifting element 15.
  • the lifting element is consequently in turn adjustable by the same lifting distance 16 as the locking pin, between the lifting positions 15, 15 'which are also drawn out and shown in broken lines in FIG.
  • the lifting member 15 is, as the eruption in Fig. 2, under the action of a spring 17.
  • the spring 17 strives for the locking pin from the lifting member 15 into the locking opening 14 of the steering column 13 to keep pressed.
  • the tip of the locking bolt 11 should not be aligned with the locking opening due to a steering column twist 13
  • the locking bolt first abuts on the circumferential surface of the steering column 12 in order to fall into the then aligned locking opening 14 during a subsequent rotation 13.
  • the components 1 1, 15, 17 consequently form a jointly movable structural unit.
  • the stroke movement of the structural unit from 11, 15 and 17, illustrated by the arrow 18 in FIG. 2, is based on the energization of an electric motor 20 triggered by control electronics.
  • This motor 20 acts on a lifting wheel 23 via a gear, eg consisting of a worm 21 and a worm wheel 22.
  • This lifting wheel 23 has two circular, axially facing lifting curves 24 on the inside of the wheel, on which the lifting member 15 is supported with two diametrical guide arms 25
  • the lifting member 15 is under the action of a restoring force 26, which starts from a return spring 27.
  • An arm 28 projects radially from the lifting member, to which a permanent magnet 30 is attached.
  • the stroke movement 18 consequently has an effect in a corresponding entrainment movement of the permanent magnet 30
  • Various electronic components are fastened on a printed circuit board 29 in the housing 19 of the ELV 10, including two Hall sensors 3 1. 32, which have different effects with respect to one another. They are initially at a distance 33 from one another which can be seen in FIG 1, 15, 17 corresponds. If both Hall sensors 31, 32 were digitally effective, then the one Hall sensor 31 would only respond to the active field of the permanent magnet if the lifting unit with its locking bolt is in the previously described dash-dotted unlocking position 1 1 ' the other Hall sensor 32 would then be activated by the permanent magnet 30 when the extended locking position of the locking pin 11 is present
  • the two Hall sensors 31, 32 thus detect the two lifting positions 15, 15 'of the lifting member.
  • the signals occurring at the outputs of the two Hall sensors are finally fed via a line 34 to an electronic evaluator 45, which monitors and detects the position of the lifting member 15 in this way.
  • the one Hall sensor 31 is digitally active and positioned such that it is only in the unlocked position 1 1 'or 15' is activated, which is why it can be referred to as an “unlocking Hall sensor”.
  • the lifting curve 24 from the lifting wheel 23 is shown in a flat angle. The ordinate of the curve in FIG.
  • FIG. 3 shows the lifting distance 16 between the two Stroke positions 15 and 15 'are entered on the ordinate, the course of the support of the guide arm 25 on the curve 24 is entered, the support location marked with 35 determining the locking position and the support location marked with 36 determining the unlocking position of the locking bolt.
  • the effective range of the unlocking Hall sensor 31 is 3 in the edge region of FIG This is also shown in Fig. 4, where the flux density in mT is given on the ordinate, while the measurement path is illustrated on the abscissa.
  • the upper signal curve, marked 41 applies to the unlocking Hall sensor 3 1. This results in the following course of action
  • the other Hall sensor 32 has an analog effect and therefore has a response range, identified by 40 in FIG. 3, which extends over a substantially greater distance than the above-described effective range 37 of the de-regulating Hall sensor.
  • This sensor 32 is therefore referred to below as “analog Hall sensor”.
  • This analog Hall sensor 32 not only detects the locking position but also informs the electronic evaluator 45 mentioned above of the time course of the signals occurring there during the stroke movement.
  • the resulting signal curve 42 is also shown in FIG Over the entire travel of the lifting member 15 between the two end positions 35, 36
  • This travel of the lifting member 15 is converted into a scaled analog voltage value and read by a microcontroller in the evaluator 45 via an A / D converter.
  • the effective range of this analog Hall sensor 32 therefore closes a uch the unlocking position 36, which is why the unlocking position is recognized redundantly.
  • the unlocking Hall sensor 31 could also have an analog mode of operation.
  • the device according to the invention can also be used in other application cases.
  • Another suitable application area was, for example, electronic ignition starter switches LIST OF REFERENCE NUMBERS

Abstract

La présente invention concerne un dispositif d'identification de position d'un élément mobile dans un système de fermeture utilisable dans des véhicules, particulièrement adapté au contrôle d'un boulon de blocage (11) d'un dispositif de verrouillage de direction électronique (10) d'un véhicule automobile. Au niveau du boulon de blocage (11) se trouve un aimant permanent (30) dans le champ d'action duquel se trouvent deux capteurs Hall (31, 32). L'un des capteurs (32) contrôle la position de verrouillage et l'autre capteur (31) contrôle la position de déverrouillage du boulon de blocage (11). Les capteurs Hall (31, 32) sont reliés à un interpréteur (45). Pour obtenir une identification de position redondante, au moins le second capteur (32) a un fonctionnement analogique. Cela permet d'obtenir un domaine de fonctionnement proportionnellement supérieur. Pour la détermination de l'une des positions du boulon de blocage (11), en particulier de sa position de déverrouillage (11'), les deux capteurs Hall sont utilisés (31, 32). L'interpréteur (45) traite non seulement les signaux provenant du premier capteur Hall (31), mais contrôle également la durée des signaux du second capteur Hall analogique (32). L'interprétation commune de ces deux signaux permet d'obtenir une identification de position redondante.
