Definitions

• the invention is directed to a device of the type specified in the preamble of claim 1.
• the sensor of the device responds to an approach or touch.
• the ID transmitter sends an identification code, in the case of an authorized person, the control electronics make a positive code comparison and the locking device enables access to the vehicle.
• the actuation of the locking device is activated before the actual actuation of a handle of the locking device is carried out by the authorized person.
• the person operating the handle is not aware of this communication and the data comparisons; opening and closing the door or a flap takes place without delay.
• a sensor To avoid unnecessary, energy-consuming communications, a sensor must not respond to the approach or touch by any object, but only by the human hand. It is undesirable if actuations of the device are brought about by any external influences, such as rain, snow, ice or leaves. For this reason, in a known locking device with a capacitive sensor (DE 196 20 059 AI), the speed of the change in capacitance, which changes when approaching or 2
• the invention has for its object to develop a reliable device of the type mentioned in the preamble of claim 1, which clearly distinguishes whether the sensor is controlled by a human hand or by error objects and accordingly sets the actuation of the locking device effective or ineffective. This is achieved according to the invention by the measures mentioned in claim 1, which have the following special significance.
• auxiliary sensor which consists of a permanent magnet and a Hall element.
• auxiliary sensor which consists of a permanent magnet and a Hall element.
• One of these two elements is arranged in the movable handle and the other in the adjacent resting carrier.
• both sensors emit separate signals, but these are evaluated together.
• the signal of the auxiliary sensor results because a vertical and / or horizontal relative movement between the Hall element and the permanent magnet takes place by actuating the handle. This leads to signals in the Hall sensor.
• the evaluation is successful, the lock is transferred to its locking position, provided that it was previously in its unlocking position. In the locked position, the operation of the handle is ineffective; the door or flap cannot be opened.
• the main sensor not only the main sensor, but also the auxiliary sensor works dynamically.
• the duration of the contact or the approach can be recorded and evaluated by both sensors.
• the common output signal resulting from the evaluation of both signals can then not only be used for the above-described reversal of the lock, but also to trigger one or more further functions in the vehicle. Whether and which functions are triggered depends on the duration of the touch.
• These other functions can be comfort actuations of moving components. For example, Close opened windows of the vehicle, switch on an alarm system, close a convertible top in the vehicle and / or fold in the side mirrors from the vehicle.
• Fig. 1 is a substantially horizontal longitudinal section through an outside door handle of a vehicle on which the device according to the invention is realized, in the direction of view of the section line I - I and
• Fig. 2 is a vertical longitudinal section through the outer door handle shown in Fig. 1 along the section line II - II.
• the locking device 10 used in the device according to the invention comprises a carrier 11, which is shown in the interior of a door 12 and not shown in detail
• the locking device 10 also includes a handle 20.
• the handle 20 is pivoted at one end 21 in the carrier 11.
• the axis 14 of the pivot bearing extends essentially vertically to the door 12, which is why the handle 20 is a so-called "pull handle".
• the other end 22 of the handle 20 has an extension with a hook end, which has an opening 15 in the outer door panel 13 and in the carrier 1 1.
• the hook end of the extension engages behind a mechanical input member 31 on a lock 30 located in the door 12.
• the lock 30 normally holds the door 12 in its closed position.
• the lock 30 can optionally be in one of two operating positions, namely a locking position and an unlocking position. If the 'handle 20 is pivoted in the direction of arrow 23 of FIG. 1, the lock member 31 is taken in the sense of the arrow 33 in FIG. 1 via the extended handle end 22. If the lock 30 is in an unlocked position, this actuation 23 of the handle 20 is effective. Then the lock 30 releases the door and the door 12 can be opened. If, on the other hand, the locking position of the lock 30 is present, the actuation 23 is ineffective; the lock member 31 is taken idle without the lock 30 releasing the door. Despite the actuation 23, the locked lock 30 remains in its closed position; the door remains closed.
• the reversal of the lock 30 can be done mechanically in an emergency, for example via a lock cylinder. Although this is not shown in detail, a further opening 16 can be seen in the carrier 11 and in the outer door panel 13, in which such a locking cylinder could be arranged.
• the locking cylinder can be operated using an emergency key.
• the key can be inserted and removed, can be integrated in a cover 17 which is fastened to the carrier 11 and is arranged flush next to the handle 20.
• the lock 30 is reversed electrically between the unlocked position and the locked position.
• the lock 30 has an electrical input 32.
• the trigger for such an electrical reversal of the lock 30 are three sensors 40, 45 and 50, which perform different functions to be described in more detail.
• Two of these sensors 40, 45 are effective in a capacitive manner in the present case.
• the respective electrodes 41, 46 are highlighted by different points for the drawings.
• the electrodes 41, 46 build up an electric field with the body of the vehicle and / or the surroundings.
• Such a field 47 of the capacitive sensor 40 is only indicated in the form of field lines in FIG. 2. If an object arrives, e.g. 3, in one of the electric fields generated by the two electrodes 41, 46, the capacitance between the electrodes 41, 46 and the vehicle or its surroundings changes. This is registered and evaluated in various ways by the associated electrical evaluation units 42, which will be described in more detail below.
• the associated components 42 emit an output signal illustrated by an arrow 43 in FIG. 1, which via electrical lines 18 in the area of the handle 20 and via an electrical cable 19 extending them in the door 12 and in the vehicle to a control unit 25 is forwarded.
• This can be a central control device 25, which acts on the various locks 30 provided on the various doors and flaps of the vehicle via numerous electrical or mechanical connections 26 that emanate from it.
• the electrical connection 26 is connected to the already mentioned electrical input 32 of the respective lock 30. 6
• control device 25 could also act mechanically on a second input member of the lock 30, not shown in detail.
• the two capacitively active sensors 40, 45 act independently of one another and in different ways from one another.
• One capacitive sensor 45 is set to be particularly sensitive and acts in a known manner on the approach of an object, in particular an authorized person. This sensor 45 serves to unlock a locked lock 30 and thus, as already described, to make the handle 20 operable 23 successfully. However, this only takes place if the following additional condition is met.
• Such a further condition for switching the lock 30 results from the fact that only authorized persons are to be allowed access to the vehicle, but not unauthorized persons.
• the authorized person carries with them an identification transmitter, which will be referred to in the following for short as “ID transmitter” and to which a corresponding identification receiver in the vehicle is assigned, which is to be called analogously "ID receiver".
• ID transmitter normally acts passively, simply by bringing the authorized person closer to the vehicle, without the person having to act on the ID transmitter or with the ID transmitter.
• an active ID transmitter is also conceivable, e.g. an electronic remote control key that must be operated by a button to be effective.
• Said first capacitive sensor 40 is made less sensitive to the opening sensor and is to be referred to below as “main sensor”.
• Main sensor 40 is only effective in coordination with said third sensor 50, which is to be called “auxiliary sensor”.
• the auxiliary sensor 50 is formed in two parts and consists of a Hall element 51 and a permanent magnet 52.
• the permanent magnet generates a magnetic field 53, illustrated in the figures by field lines, in the area of which the Hall element 51 is located. While the Hall element 51 is located close to the end wall in the cavity 24 of the handle 20, the permanent magnet 52 is arranged on the inside of the adjacent wall of the cover 17 mentioned.
• the contact area not only responds, as already mentioned, to the main sensor 40, but also to the auxiliary sensor 50.
• the contact results in a relative movement of the handle 20 with respect to the carrier 11, which is caused by the bearing 14 or by a game in this storage can be done.
• Vertical and / or horizontal movements can occur when touched. This is illustrated in FIG. 2 by a force arrow 34; pressure is exerted on the contact point 28 by the finger 27.
• the relative movement of the Hall element 51 illustrated by the movement arrow 35 in FIG. 2, takes place in the stationary magnetic field 53 of the permanent magnet 52.
• the main sensor 40 can become active as soon as the finger approaches it, but at the latest when the contact point 28 of FIG. 2 is actually actuated. Then the main and the flow sensors give their own signals to their control and evaluation units 42 down, but both signals are evaluated together. Only when both signals have been correctly determined by the evaluation units 42 is an output signal 43 generated which, as already mentioned, the control unit 25 8 is supplied. In the event of success, the control device 25 effects the aforementioned reversal of the lock 30 into its locking position.
• Both the main sensor and the auxiliary sensor work dynamically.
• the duration of the contact or the approach of both sensors can thus be recorded and evaluated.
• the duration of the touch is determined by the auxiliary sensor and results in a correspondingly modified output signal 43.
• one or more other functions can then be triggered in the vehicle in addition to the reversing of the lock 30 already mentioned. These are particularly advantageous for so-called comfort actuation of moving components in the vehicle. Which convenience functions result from this has already been given above, for example.
