Abstract

The device has a vehicle-sided sensor (5) transmitting an initialization signal (7) to operator-specific identification element by a vehicle-sided transmission unit (6) after the activation of the sensor. The initialized identification element directly transmits an operating signal (8) to a vehicle-sided receiving unit (9) for the admission of a door (10) and a lid (11), where the receiving unit is designed independent of the transmission unit. The identification element has transmitting and receiving units.

Description

  • The Invention relates to a keyless actuation and / or locking device for motor vehicles in particular, with a user-specific identification element with a transceiver unit, and with a vehicle-side sensor, which after its release by means of at least one likewise vehicle-side transmitting unit an initialization signal transmitted wirelessly to the identification element.
  • Such a keyless operating and / or locking device for particular motor vehicles is in the DE 10 2005 031 186 A1 presented. This is primarily about converting an active keyless entry system into a passive keyless entry system in a simple way. For this purpose, an actuating device, for example an outside door handle, is additionally equipped with a control unit which is in communication with the transmitting unit and the sensor.
  • As is known, an active keyless entry system operates with a user-specific identification element, which is also referred to as an ID transmitter (identification transmitter). In order to gain access to the vehicle, a user guiding the identification element must press a button on the relevant identification element. As a result, an identification routine between the external identification element and a vehicle-side receiving unit or transmitting and receiving unit is started. If the external identification element proves to be justified, a door, flap etc. are acted upon accordingly. Mostly a central locking element is released for this purpose. Such approaches are known, including only by way of example to the WO 02/084604 A1 referenced.
  • Besides So-called passive keyless entry systems are known. In these the accessing user has an external and also user-specific ID transmitter with him, whose authorization is then queried if the vehicle-side sensor by a trigger signal a bidirectional data exchange starts. That is, the Permission query is usually approaching the sensor or its release started and not - like on the active system - by pressing the user. If the external ID provider proves to be authorized again, in turn, the door, flap, etc. are released, for example, by releasing the associated central locking element becomes.
  • Of the Invention is the technical problem underlying such keyless operating and / or locking device for so on in particular to develop motor vehicles that the costs are reduced.
  • to Solution of this technical problem proposes the invention in a generic keyless Actuation and / or closing device for In particular motor vehicles that the initialized identification element directly a wireless actuation signal to a vehicle-side Receiving unit for loading a door, flap, etc. sends. In this case, the vehicle-side receiving unit is technological and also spatially independent of the sensor cooperating also designed vehicle-side transmitting unit.
  • According to the invention So the benefits of both the passive and the active Keyless entry system combined. Because the user is not required, a switch for starting, for example, a decision or locking routine. Rather, the unlocking or interlocking wireless data exchange between the identification element and the vehicle-side receiving unit started as soon as the identification element is initialized. This initialization takes place as soon as the user-specific identification element after triggering the vehicle-side sensor the associated and initialization signal output from the vehicle-side transmitting unit received wirelessly.
  • There a mandatory in the prior art connection between the vehicle-side sensor or the local transmission unit and the Receiving unit is not required, the constructive and Technological effort is significantly reduced and will result this reduces the costs. Incidentally, you can the installation of on the one hand the sensor and the transmitting unit and on the other hand, independent of the transmitting unit receiving unit be chosen practically variable without being on a wired Connection must be considered. This means, This results in a special installation and connection variability, the the state of the art is unable to deliver.
  • in principle can the initialization signal with an access authentication flanking the authorization of the identification element checks the vehicle or door in question, To be allowed to operate flap etc.
  • Since, in this case, a bidirectional data exchange usually takes place between the user-specific identification element and the vehicle-side transmitting unit, the vehicle-side transmitting unit in question is advantageously designed as a first transmitting / receiving unit. The relevant first transceiver exchanges with the ID wirelessly and bi-directionally data to verify or falsify the authorization of the identifier. Only if the authorization of the identification element has been determined in this conditional access check, the identification element is initialized and this is immediately followed by the wireless delivery of the actuation signal to the vehicle-side receiving unit for acting on the door, flap, etc. However, the invention mostly relies on unidirectional data exchange between the operator-specific identification element and the vehicle-side transmission unit.
  • In In this context, the initialization signal is mostly unique used to "wake up" the identification element, thus immediately emitted the questionable actuating signal becomes. That is, the above-described conditional access check and the associated bidirectional data exchange only a non-compulsory option. Because mostly finds a unidirectional Data exchange instead, so that the initialization signal so work and act like a conventional radio remote control, by the initialized identification element immediately the Actuating signal to the vehicle-side receiving unit for loading the door, flap etc. gives.
  • The means the triggered sensor or proximity sensor starts in conjunction with the associated vehicle-side Sending unit, the user-specific identification element in Shape practically a radio remote control. Only the triggering Start button has been replaced by the described routine. - In The rule is the initialization or the initialization signal connected to the described conditional access examination.
  • In order to the triggered sensor directly to the transmitting unit for Can apply delivery of the wireless initialization signal, and as delay-free as possible, that's it proven when the vehicle-mounted sensor and the question Send unit form a structural unit. That goes for sure also in the event that instead of the transmitting unit the first transmitting / receiving unit together with the sensor to the respective Unit is united. In any case, the unit is outside attached to the motor vehicle, so that any radiation inside the vehicle not observed due to the metallic shielding of the passenger compartment become. Any negative influences on the radio, the engine electrics etc. are thereby excluded. It has an outer Attachment of the assembly from the vehicle-side sensor and the Transmitting unit or the first transceiver unit in an exterior mirror, behind or in a bumper, in one or on one Operating element for the tailgate etc. proven. As a particularly preferred installation location for the unit the invention proposes the outside door handle or its interior.
  • Next the optional first transmitting / receiving unit as part of vehicle-mounted unit from the sensor and the transmitting unit or the first transmitting / receiving unit, the invention has another second transmitting / receiving unit. Because the vehicle side Receiving unit may be as such a second transmitting / receiving unit be formed. Mostly the vehicle-side receiving unit or the second transmitting / receiving unit in an already existing vehicle side Integrated control unit. It goes without saying that the two Transmitter or transceiver units spatially and technologically from each other are separated and work independently.
  • In order to there is no mutual interference of the wireless transmission links between on the one hand the transmitting unit emitting the initialization signal and on the other hand, the actuating signal emitted by the identification element, operate the initialization signal and the actuation signal with different carrier frequencies. In both cases usually digital signals are exchanged by defines a corresponding modulation of the carrier frequency be, for example, in the sense of FSK modulation (Frequency Shift keying). It has proven useful when the initialization signal is located in the LF (low frequency) range, while the Actuating signal as HF (high frequency) signal is present.
  • Usually the initialization signal will be in the range between 30 kHz and 300 kHz, whereas the actuation signal is above 1 MHz is settled. This can be a mutual Influencing the initialization signal and the actuation signal safely exclude and can the vehicle-side Sending unit for the initialization signal on the one hand and the on-vehicle reception unit for the operation signal on the other hand, each technologically designed differently and do not respond to the respective corresponding signal.
  • The device according to the invention can be retrofitted to an existing motor vehicle simply by replacing, for example, the radio remote control used there with the user-specific identification element. In addition, the assembly of the vehicle-mounted sensor and the transmitting unit must be mounted, which is not difficult, because this is a self-sufficient to a required power supply unit. In this context, it has further proven, if the sensor is designed as a capacitive sensor, because this already Approaches of the user willing to enter the sensor can be detected and trigger the initialization signal. A touch of the relevant capacitive sensor is therefore not required. Finally, for reasons of a compact design and cost-effective design, the vehicle-side transmitting unit is usually equipped with an integrated antenna.
  • in the The result is a keyless operation and / or closing device for motor vehicles in particular provided the benefits of a passive connects with those of an active keyless entry system. Because a switch operation of the identification element is not mandatory. However, as a result of wireless data traffic the initialized identification element with the vehicle-side Receiving unit be ensured that, for example, a Flap, door etc. is already unlocked as soon as the operator or User reaches the vehicle and unlocked each Door lock by, for example, pressing the Would like to open the door outside handle. This represents a considerable comfort gain. Here are to see the main advantages.
  • in the The invention will be described below with reference to a purely exemplary embodiment descriptive drawing explained in more detail; show it:
  • 1 the keyless actuation and / or closing device in a motor vehicle schematically and
  • 2 the outside door handle in detail.
  • In the figures, a keyless actuation and / or closing device is shown, which is exemplary in a motor vehicle 1 is used. Basically, instead of the motor vehicle 1 Also, any other vehicle, such as a boat, motorcycle, etc. are equipped with the device to be described below in detail.
  • The basic structure includes a user-specific identification element 2 , which is carried by an entrant user. The operator-specific identification element 2 is with a transmitting / receiving unit 3 . 4 equipped. In addition to the operator-specific identification element 2 belongs to the essential structure of a vehicle-mounted sensor 5 , which according to the invention with a likewise vehicle-side transmitting unit 6 a structural unit 5 . 6 forms. The construction unit in question 5 . 6 taken together outside of the motor vehicle 1 appropriate, as evidenced by 2 inside an outside door handle T and thus outside a passenger compartment F. This allows electromagnetic interference in the interior of the metallic shielded passenger compartment F side of the transmitting unit 6 be avoided.
  • At the sensor 5 it is not limited to a capacitive sensor which detects approaches by the user who is willing to enter, for example as described in US Pat EP 1 235 190 B1 which is expressly referred to at this point.
  • As soon as the sensor 5 is triggered, ensures the appropriate trigger signal in the vehicle-side transmitting unit 6 that the sending unit in question 6 an initialization signal 7 to the identification element 2 transmitted. This happens in the present case wirelessly and with a carrier frequency in the LF range.
  • As a result, the identification element becomes 2 initialized. This means within the scope of the invention that the identification element 2 "Awakened" is followed by an actuation signal 8th transmits wirelessly. This actuation signal 8th is sent to a vehicle-side receiving unit 9 transmitted to, for example, a door 10 , a flap 11 etc. to operate, for. B. to unlock or lock. This can be done in such a way that in a vehicle-mounted control unit 12 integrated receiver unit 9 a not explicitly shown central locking element in the sense of "unlock" or "locking" acted upon.
  • Based on 2 one recognizes that the vehicle-side capacitive sensor 5 and the transmitting unit 6 a structural unit 5 . 6 form. The construction unit 5 . 6 taken together outside the vehicle 1 appropriate. In the context of the embodiment and not limiting, the unit is found 5 . 6 in the outside door handle T. Also not restrictive works the initialization signal 7 as if it were a wake-up signal.
  • The authorization check takes place in the course of the exchange of the actuation signal 8th instead of. This is the actuation signal 8th bidirectionally between the vehicle-side receiving unit or transmitting / receiving unit 9 and the identification element 2 exchanged to the already described authorization check of the identification element 2 make.
  • In any case, the initialization signal is working 7 on the one hand and the actuating signal 8th on the other hand with different carrier frequencies, namely the initialization signal 7 in the LF range, whereas the actuation signal 8th is located in the HF range. This allows the transmitting unit 6 and the receiving unit 9 or transmitting / receiving unit 9 not difficult technologically and also spatially independent pending from each other in the motor vehicle 1 be interpreted.
  • The sensor 5 and the transmitting unit 6 are considered to be a necessary and implied power supply 13 as a self-sufficient unit 5 . 6 formed inside the outside door handle T. It can be seen that the transmitting unit 6 an integrated antenna 14 having. In the same way, the identification element or the ID transmitter 2 with respective antennas 15 . 16 equipped. This includes the antenna 15 to the transmitting unit 3 in the identification element 2 while the antenna 16 Part of the receiving unit 4 inside the identification element 2 is. Both antennas 15 . 16 like in the respective transmitter / receiver unit 3 . 4 be integrated.
  • The receiving unit 4 including the antenna 16 is only tuned to LF signals or can only the initialization signal 7 from the transmitting unit 6 receive. In contrast, the transmitting unit sends 3 including the antenna 15 only in the RF range, because they are responsible for the transmission of the actuation signal 8th responsible. With the help of the vehicle-side transmitting unit 6 including the integrated antenna 14 this becomes the receiving unit 4 associated LF signal or the initialization signal 7 generated. In contrast, the vehicle-side receiving unit reacts 9 only to the RF signal or that of the transmitting unit 3 of the identification element 2 or its antenna 15 emitted actuation signal 8th , Since all signals are transmitted and received in non-overlapping frequency ranges, mutual influences are not to be feared and the individual signals can 7 . 8th be properly separated from each other.
