Description
Verfahren zum Ansteuern einer Notentriegelung einer Abdeckung einer Medienzu- fuhreinrichtung bei einem Kraftfahrzeug Method for activating an emergency release of a cover of a media feed device in a motor vehicle
Die Erfindung betrifft ein Verfahren zum Ansteuern einer Notentriegelung einer Karosserieklappe zum Abdecken einer Einfülleinrichtung eines Kraftstoffbehälters für einen gasförmigen Kraftstoff, insbesondere Wasserstoff, für ein Kraftfahrzeug. The invention relates to a method for controlling an emergency release of a body flap for covering a filling device of a fuel tank for a gaseous fuel, in particular hydrogen, for a motor vehicle.
Solche Karosserieklappen, insbesondere zum Abdecken von Einfülleinrichtungen von in Kraftfahrzeugen angeordneten Behältern für beispielsweise Wasserstoff einer Tankanlage, sind bei Kraftfahrzeugen bekannt. Die Karosserieklappe zum Abdecken einer Einfülleinrichtung dient dazu, ein Eindringen von Verunreinigungen und Feuchtigkeit im Bereich einer Tankmulde zu reduzieren, sowie ein ansprechendes Äußeres herzustellen, indem die Karosserieklappe als Tankklappe eine Einfülleinrichtung nach außen hin kaschiert. Es sind verschiedene Betätigungsmechanismen für solche Tankklappen bekannt. Im Falle einer Betankung mit Wasserstoff, gibt es zur Medien- befüllung des Kraftfahrzeugs zum Beispiel elektrisch ausgelöste Klappen, bei denen beim Druck auf die Tankklappe mit einer bestimmten Kraft ein HAL-Sensor bzw. ein Mikroschalter geschaltet wird. Such body flaps, in particular for covering filling devices of containers arranged in motor vehicles, for example for hydrogen of a tank system, are known in motor vehicles. The body flap for covering a filling device serves to reduce the ingress of contaminants and moisture in the area of a tank trough and to produce an attractive appearance in that the body flap, as a tank flap, conceals a filling device to the outside. Various actuation mechanisms for such tank flaps are known. In the case of refueling with hydrogen, for example, there are electrically triggered flaps for media filling of the motor vehicle in which a HAL sensor or a microswitch is switched with a certain force when pressure is applied to the tank flap.
Außerdem ist es bekannt, solche Klappen auch durch eine Zentralverriegelung des Kraftfahrzeugs zu öffnen und zu verschließen, die dieses mit anderen Türen und Klappen am Kraftfahrzeug, gesteuert zum Beispiel mittels eines Funksignals, ausgelöst durch eine Bedienperson, gewöhnlich durch einen sich außerhalb des Kraftfahrzeugs befindlichen Fahrer, ebenfalls bewerkstelligt. It is also known to open and close such flaps also by a central locking of the motor vehicle, this with other doors and flaps on the motor vehicle, controlled for example by means of a radio signal triggered by an operator, usually by an outside of the motor vehicle driver , also done.
Beim Auftreten eines Defekts oder einer Fehlfunktion ist insbesondere für die Tankklappe eine Notentriegelung vorteilhaft, damit eine Bedienperson eine notwendige Medienbefüllung des Tanks, also eine Betankung, vornehmen kann, um eine Weiterfahrt des Kraftfahrzeugs sicherzustellen. When a defect or a malfunction occurs, an emergency unlocking is advantageous, in particular for the tank flap, so that an operator can carry out a necessary media filling of the tank, that is to say a refueling, in order to ensure that the motor vehicle continues to travel.
Deshalb ist es Aufgabe der Erfindung, ein Verfahren zum Ansteuern einer Notentriegelung einer Abdeckung einer Medien-Einfülleinrichtung eines Kraftfahrzeugs vorzu- schlagen, das die Notentriegelung durch einen Fahrer als zuverlässigen Prozess gestaltet, auch wenn der Fahrer eine solche Notentriegeiung nur selten ausführt. It is therefore an object of the invention to provide a method for actuating an emergency release of a cover of a media filling device of a motor vehicle. which makes the emergency release by a driver as a reliable process, even if the driver rarely performs such emergency training.
Die Aufgabe wird erfindungsgemäß durch die Verfahrensschritte nach dem ersten Patentanspruch gelöst. Eine bevorzugte Verfahrensergänzung beschreibt der zweite Patentanspruch und bevorzugte Einrichtungen zur Durchführung des Verfahrens beschreiben die weiteren abhängigen Ansprüche. The object is achieved by the method steps according to the first claim. A preferred method supplement describes the second claim and preferred means for carrying out the method describe the further dependent claims.
Nach der Erfindung ist ein Verfahren zur Notentriegelung einer Abdeckung einer Me- dienzufuhreinrichtung bei Stillstand eines Kraftfahrzeugs, wodurch diese durch Öffnen einer Karosserieklappe von außen zugänglich gemacht wird, wozu, aufgrund einer Betätigungshandlung oder Signalauslösung einer Person, durch ein Steuergerät eine Verschlusseinrichtung der Karosserieklappe mittels einer Antriebseinrichtung in eine entriegelte Stellung gebracht wird, dadurch gekennzeichnet, dass das Steuergerät mittels wenigstens einer Signalauslösung oder eine Person mittels wenigstens einer Betätigungshandlung zusätzlich zur Antriebseinrichtung zur Entriegelung folgende weitere Funktionen auslöst: According to the invention, a method for emergency unlocking a cover of a media supply device at standstill of a motor vehicle, making it accessible by opening a body flap from the outside, including, due to an act or signal triggering a person by a control device a closure device of the body flap by means of a Drive device is brought into an unlocked position, characterized in that the control unit triggers the following additional functions by means of at least one signal triggering or a person by means of at least one actuating action in addition to the drive device for unlocking:
- Deaktivierung der Fahrbereitschaft des Kraftfahrzeugs und - Deactivation of the driving readiness of the motor vehicle and
- Demobilisierung des Kraftfahrzeugs durch eine mechanische Einrichtung und - Demobilization of the motor vehicle by a mechanical device and
- Abschaltung und/oder Blockierung einer Medienzufuhr zum Betrieb des Kraftfahrzeugs und/oder - Shutdown and / or blocking of a media supply to the operation of the motor vehicle and / or
-Entsperrung eines Betankungsweg-Schließventils des Kraftfahrzeugs. -Blocking a refueling path closing valve of the motor vehicle.
Das hat den Vorteil, dass eine Bedienperson, insbesondere der Fahrer des Fahrzeugs, auch bei einem defekten Verriegelungsmechanismus an der Tankklappe, tanken kann und dabei die gesetzlichen Bedingungen erfüllt werden, ohne dass die Person anderweitig aktiv werden muss. Insbesondere für das Not-Befüllen eines Wasserstofftanks ist dadurch eine große Sicherheit gewährleistet. Nachdem die weiteren Funktionen erfüllt sind, kann steuergeräteseitig von einem Status Tankvorbereitungen in einen Status Tanken gewechselt und ein Betankungsprozess durchgeführt werden. Zusätzlich oder alternativ kann die Bedienperson auch auf notwendige Betriebsänderungen mittels einer Anzeigeeinrichtung hingewiesen werden. Das Verfahren nach der Erfindung kann vorteilhafterweise dadurch weitergebildet sein, dass ein Schließen der Karosserieklappe oder eine Aufhebung des Notentriegelungsstatus die weiteren Funktionen deaktiviert, so dass das Kraftfahrzeug für einen Fahrbetrieb bereit ist. This has the advantage that an operator, especially the driver of the vehicle, even with a defective locking mechanism on the fuel filler flap, can refuel and thereby meet the legal requirements, without the person must be otherwise active. In particular for the emergency filling of a hydrogen tank thereby a great security is guaranteed. After the other functions have been fulfilled, it is possible on the ECU side to change from a status of tank preparations to a status of fueling and to carry out a refueling process. Additionally or alternatively, the operator can also be notified of necessary changes in operation by means of a display device. The method according to the invention can advantageously be further developed in that closing the body flap or canceling the emergency unlocking status deactivates the further functions, so that the motor vehicle is ready for a driving operation.
Eine bevorzugte Ausführung der Einrichtung zur Durchführung des Verfahrens sieht vor, dass diese wenigstens mit einer Eingabeeinheit zur Übermittlung eines Notentriegelungssignals an das Steuergerät ausgestattet ist. Eine solche Eingabe kann durch eine Bedienperson, insbesondere durch den Fahrer, mittels eines Schalters oder Tasters oder einer Hard-/Softwareschnittstelle, wie einer Eingabeeinheit für Navigation, Radio und/oder andere fahrspezifische Befehle erfolgen, um dann an das Steuergerät weitergeleitet zu werden. Weiter vorteilhaft ist, wenn letzteres wenigstens über eine Ausgabeeinheit Informationen an die Bedienperson übermitteln kann. Eine solche Ausgabeeinheit kann zum Beispiel eine Anzeigeeinheit mit Bildschirm sein, wie sie nach dem Stand der Technik im Kraftfahrzeug bereits in Zusammenhang mit Navigationsgeräten verwendet wird. Allerdings ist auch eine Sprachausgabeeinheit denkbar, insbesondere, wenn die Bedienperson außerhalb des Kraftfahrzeugs erreicht werden soll. A preferred embodiment of the device for carrying out the method provides that it is equipped with at least one input unit for the transmission of an emergency release signal to the control unit. Such an input may be made by an operator, in particular by the driver, by means of a switch or button or a hardware / software interface, such as an input unit for navigation, radio and / or other driving-specific commands to then be forwarded to the controller. It is also advantageous if the latter can transmit information to the operator via at least one output unit. Such an output unit may be, for example, a display unit with a screen, as is already used in the motor vehicle in connection with navigation devices in the prior art. However, a voice output unit is also conceivable, in particular if the operator is to be reached outside the motor vehicle.
Muss eine Notentriegelung von einer befugten Person über eine Eingabeeinheit veranlasst werden, kann davon ein Aktivieren eines Tankwunsches durch Betätigen der Tankklappe durch eine nicht autorisierte Person, zum Beispiel an einem an einer Ampel stehenden Fahrzeug, eindeutig vom Steuergerät unterschieden werden und es können dann Anzeigen von Handlungsanweisungen für einen Fahrer zur Herstellung einer Betankungsbereitschaft des Fahrzeugs automatisch unterdrückt werden. Außerdem ist es von Vorteil, dass eine fehlerhaft offen erkannte Tankklappe oder eine fehlerhaft erkannte angekuppelte Betankungs-Ladeeinrichtung nicht zum Deaktivieren der Fahrbereitschaft und Ausschalten zum Beispiel einer Brennstoffzelle, sowie gegebenenfalls Einlegen von Auto-P oder Aktivieren der Feststellbremse führt. If an emergency release by an authorized person via an input unit can be made, it can be clearly distinguished from the control unit activation of a tank request by pressing the fuel filler flap by an unauthorized person, for example, at a standing at a traffic light vehicle and it can then display from Instructions for a driver to produce a refueling readiness of the vehicle are automatically suppressed. In addition, it is advantageous that a faulty open recognized fuel door or a faulty detected coupled refueling charging device does not lead to disabling the driving readiness and off, for example, a fuel cell, and optionally inserting Auto-P or activating the parking brake.
Eine vorteilhafte Ausführung der Einrichtung zur Durchführung des Verfahrens sieht vor, dass das Steuergerät eine erfolgte Notentriegelung detektiert, wenn folgende Bedingungen erfüllt sind, das Fahrzeug befindet sich im Stillstand, die Karos- serieklappe wechselt ihren Status von geschlossen zu offen und das Notentriegelungssignal wurde vom Steuergerät empfangen. An advantageous embodiment of the device for carrying out the method provides that the control unit detects a successful emergency release, if the following conditions are met, the vehicle is at a standstill, the Karos- The serial door changes its status from closed to open and the emergency unlock signal is received from the controller.
Das hat den Vorteil, dass eine notwendige Notentriegelung softwareseitig erkannt wird und keine Eingabe durch eine Person erfolgen muss. Hier kann zum Beispiel ausgewertet werden, ob davor von der Bedienperson ein Betankungswunsch eingegeben wurde der, trotz erfüllten Bedingungen für eine Betankung, nicht zum Öffnen der Tankklappe geführt hat, obwohl das Steuergerät diese freigegeben hat. This has the advantage that a necessary emergency release is recognized by the software and no input must be made by a person. Here it can be evaluated, for example, whether previously a refueling request was entered by the operator who, despite fulfilled conditions for refueling, did not open the fuel filler flap, although the control unit has released it.
Eine weitere bevorzugte Ausführung der Einrichtung zur Durchführung des Verfahrens sieht vor, dass ein Notentriegelungssignal mittels eines Sensors ermittelt und an das Steuergerät weitergegeben wird. Vorteilhafterweise kann hierzu ein Zugseil, Bestandteil der Notentriegelung, als Detektionseinheit verwendet werden, dessen Widerstand sich ändert oder ein pietzoeffektbasierter Sensor oder ein Schalter in der Notentriegelungseinheit. A further preferred embodiment of the device for carrying out the method provides that an emergency unlocking signal is determined by means of a sensor and forwarded to the control unit. Advantageously, for this purpose, a pull rope, part of the emergency release, can be used as a detection unit whose resistance changes or a pietzoeffektbasierter sensor or a switch in the emergency release.
Von besonderem Vorteil für die Sicherheit bei einer Betankung mit Wasserstoff ist, wenn die Notentriegelung der Karosserieklappe und die Entsperrung des Betan- kungsweg-Schließventils durch eine Stromversorgung von deren Antriebskomponenten vollzogen wird. Of particular advantage for the safety of hydrogen refueling is when the emergency unlocking of the body flap and the unlocking of the refueling shut-off valve are performed by a power supply from their drive components.
Eine Notentriegelung kann auch durch die Auswertung verschiedener Signale des Fahrzeuges in Kombination mit der offenen Tankklappe erkannt werden. An emergency release can also be detected by evaluating various signals from the vehicle in combination with the open fuel filler flap.
Diese Signale können, um die Notentriegelungseinheit zu erreichen, eine unmittelbar davor geöffnete Heckklappe sein, eine Fahrerabwesenheitserkennung oder die Historie eines Tankwunschtasters, die aufzeigt, wann zuletzt ein Betankungswunsch eingegeben wurde. These signals may be to reach the emergency unlocking unit, a tailgate opened immediately in front of it, a driver's absence detection or the history of a tank request button, indicating when a refueling request was last entered.
Insgesamt kann durch das erfindungsgemäße Verfahren eine bessere Fahrzeugverfügbarkeit erreicht werden, und es wird eine fehlerhafte Tankklappenerkennung und ein Missbrauch durch Dritte ausgeschlossen. Eine Betankung ist auch bei defektem Zentralvernegelungssteller möglich, als auch bei defekter Spannungsversorgung, da eine zusätzliche redundante, jedoch durch die Bedienperson aktivierbare, Span- nungsversorgung und/oder eine mechanische Aktivierung für das Betankungsweg- Schließventil vorgesehen ist. Overall, a better vehicle availability can be achieved by the method according to the invention, and it is a faulty fuel door recognition and abuse by third parties excluded. Refueling is also possible with a defective central controller, as well as with a defective power supply, since an additional redundant, but activatable by the operator, Span- supply and / or a mechanical activation for the refueling valve closing valve is provided.
Die Notentriegelung der Abdeckung und das Aktivieren des Betankungsweg- Schließventils mittels einer zusätzlichen Spannungsversorgung, möglichst positioniert in der Nähe der Notentriegelung und von der Bedienperson daher einfach aktivierbar, damit der Tank befüllt werden kann. Während der Betankung kann die Bedienperson dann im Bedarfsfall Hinweise von der Ausgabeeinheit erhalten, zum Beispiel, die Betankung besonders zu beobachten und gegebenenfalls abzubrechen, außerdem nach dem Betanken die Spannungsversorgung des Betankungsweg- Schließventils wieder zu deaktivieren. The emergency release of the cover and activating the refueling path closing valve by means of an additional power supply, preferably positioned in the vicinity of the emergency release and therefore easily activated by the operator so that the tank can be filled. During refueling, the operator can then, if necessary, receive instructions from the output unit, for example, to observe the refueling particular and cancel if necessary, also after refueling to disable the power supply of the refueling valve closing valve again.
Alternativ kann das Betankungsweg-Schließventil auch mechanisch vom Kunden aktivierbar und deaktivierbar sein. Entweder über ein mechanisch und elektrisch aktivierbares Betankungsweg-Schließventil oder über ein weiteres mechanisches Ventil parallel zu dem Hauptpfad des Betankungsweg-Schließventils. Alternatively, the refueling path closing valve may also be mechanically activated and deactivated by the customer. Either via a mechanically and electrically activatable refueling path closing valve or via another mechanical valve parallel to the main path of the refueling path closing valve.
Als zusätzliche Spannungsversorgung kann für das Betankungsweg-Schließventil entweder die Bordnetzspannung oder eine externe Spannungsquelle verwendet werden. Hierbei ist es sinnvoll, einen elektrischen Schalter im fahrzeugseitigen Lei- tungsumfang vorzusehen, der ein Notaussignal des Fahrzeuges umsetzt, indem er die Versorgung des Betankungsweg-Schließventils unterbricht, damit die Bedienperson nicht manuell die Versorgung trennen muss, falls fahrzeugseitig eine entsprechende Fehlermeldung übermittelt wird. As an additional power supply can be used for the refueling valve closing valve either the vehicle electrical system voltage or an external power source. In this case, it makes sense to provide an electrical switch in the vehicle-side line extent, which implements an emergency stop signal of the vehicle by interrupting the supply of refueling valve closing valve, so that the operator does not have to manually disconnect the supply, if a corresponding error message is transmitted on the vehicle side.
