Description

Fernbedieneinrichtung für KraftfahrzeugeRemote control device for motor vehicles
Die Erfindung bezieht sich auf eine Fernbedieneinrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a remote control device according to the preamble of patent claim 1.
Eine derartige Fernbedieneinrichtung ist aus der DE 40 03 280 A der Anmelderin bekannt. Diese Druckschrift befasst sich mit dem Problem der Abhörsicherheit. Hierfür ist ein Frage-Antwortsignaldialog zwischen Fahrzeug und tragbarem Sender vorgesehen, bei dem einer der beiden Sender eine kurze Reichweite besitzt.Such a remote control device is known from DE 40 03 280 A of the Applicant. This document deals with the problem of privacy. For this purpose, a question-answering dialogue between the vehicle and the portable transmitter is provided in which one of the two transmitters has a short range.
Ferner ist in der Druckschrift die Möglichkeit beschrieben, Fahrzeugeinrichtungen zu betätigen, deren Betätigungs- bzw. Bewegungsvorgang mehrere Sekunden beträgt. Hierzu zählt das Schließen bzw. Öffnen von Seitenfenstern bzw. Dachöffnungen des Kraftfahrzeugs. Diese Vorgänge sollen auch in großer Entfernung vom Kraftfahrzeug aus auslösbar sein.Furthermore, the publication describes the possibility of actuating vehicle devices whose actuation or movement process amounts to several seconds. This includes the closing or opening of side windows or roof openings of the motor vehicle. These processes should also be able to be triggered at a great distance from the motor vehicle.
Probleme können sich aus einer möglicherweise fehlenden Kontrolle und der beschränkten Eingriffsmöglichkeit des Bedieners ergeben.Problems can arise from a possibly lack of control and the limited intervention of the operator.
Der Erfindung liegt die Aufgabe zugrunde, eine Fernbedieneinrichtung der eingangs genannten Art zu schaffen, bei der Fahrzeugeinrichtungen, deren Betätigungs- bzw.The invention has for its object to provide a remote control device of the type mentioned, in the vehicle devices whose actuation or
Bewegungsvorgang mehrere Sekunden beträgt, unter größtmöglicher Kontrolle undMovement process is several seconds, with the greatest possible control and
Eingriffsmöglichkeit des Bedieners betätigbar sind.Intervention of the operator are actuated.
Die Erfindung löst diese Aufgabe durch die kennzeichnenden Merkmale desThe invention solves this problem by the characterizing features of
Patentanspruchs 1.Patent claim 1.
Die Betätigung der Fahrzeugeinrichtung hängt von zwei Bedingungen ab: Der Bediener befindet sich in einer Entfernung von wenigen Metern vom Fahrzeug und er sendet das Bediensignal kontinuierlich oder in regelmäßigen Abständen aus.The operation of the vehicle equipment depends on two conditions: the operator is located at a distance of a few meters from the vehicle and he sends the operating signal continuously or at regular intervals.
Durch den geringen Abstand vom Fahrzeug ist eine optimale Sichtkontrolle und des Bedieners gewährleistet. Die Eingriffsmöglichkeit wird sichergestellt, indem der Bediener den Betätigungsvorgang durch Sendeabbruch jederzeit unterbrechen kann.The small distance from the vehicle ensures optimal visual control and the operator. The possibility of intervention is ensured by the Operator can interrupt the actuation process by sending interruption at any time.
Die Bedingung, dass sich der Bediener in einer Entfernung von wenigen Metern vom Fahrzeug aus befindet, kann auf unterschiedliche Weise erfüllt werden. Am einfachsten ist dies mit einem kurzreichweitigen Sender für das Bediensignal möglich.The condition that the operator is at a distance of a few meters from the vehicle can be met in different ways. The easiest way to do this is to use a short-range transmitter for the control signal.
Demgegenüber ergibt sich eine Erhöhung der Funktionssicherheit, wenn der tragbare Sender das Bediensignal nur aussendet, wenn er ein vom Fahrzeug ausgesandtes Fragesignal empfängt. Der hierfür im oder am Kraftfahrzeug installierte stationäre Sender für das Fragesignal kann in seinen Sendeeigenschaften im Gegensatz zu einem mobilen Sender exakt eingestellt werden. Dies gilt sowohl für die Sendecharakteristik als auch die Sendeleistung. Durch die vorgegebene kurze Reichweite des Fragesignals kann sichergestellt werden, dass sich der Bediener bei Abgabe des Bediensignals in einer Entfernung von wenigen Metern vom Fahrzeug aus befindet. Alternativ kann diese Bedingung auch wie bereits angegeben durch eine kurze Reichweite des Bediensignals erfüllt werden.In contrast, there is an increase in functional reliability when the portable transmitter emits the operating signal only when it receives an interrogation signal emitted by the vehicle. The stationary transmitter for the question signal installed in or on the motor vehicle can be set precisely in terms of its transmission characteristics, in contrast to a mobile transmitter. This applies to both the transmission characteristic and the transmission power. The predetermined short range of the question signal can ensure that the operator is at a distance of a few meters from the vehicle when the control signal is issued. Alternatively, this condition can also be met, as already indicated, by a short range of the operating signal.
Eine weitere Erhöhung der Zuverlässigkeit ergibt sich, wenn das Fragesignal vom stationären Sender nur aussendbar ist, wenn der im oder am Kraftfahrzeug installierte Empfänger das Bediensignal empfängt. Somit ist sichergestellt, dass sich der Bediener während des Sende-Empfangsvorgangs stets in Reichweite des Fahrzeugs befindet. Der Sende-Empfangsvorgang wiederum dauert solange, wie die o.g. Fahrzeugeinrichtung betätigt wird.A further increase in reliability results when the question signal from the stationary transmitter can only be transmitted if the receiver installed in or on the motor vehicle receives the operating signal. This ensures that the operator is always within range of the vehicle during the send-receive process. The transmission-reception process, in turn, lasts as long as the o.g. Vehicle equipment is operated.
Nunmehr kann auch das Problem des kleinen Abstands zwischen Bediener und Fahrzeug elegant gelöst werden, indem der Sender für das Fragesignal eine Reichweite von nur wenigen Metern besitzt.Now, the problem of the small distance between operator and vehicle can be elegantly solved by the transmitter for the question signal has a range of only a few meters.
Dadurch ist es möglich, die genannten Vorrichtungen wie Seitenfenster, Dachöffnungen oder Kofferraumdeckel per Fernbedienung zu öffnen und insbesondere zu verschließen, ohne hierfür am jeweils betätigten Fahrzeugteil zusätzliche Sicherungseinrichtungen, wie eine Einklemmschutzeinrichtung im Fensterrahmen vorzusehen.This makes it possible to open said devices such as side windows, roof openings or trunk lid by remote control and in particular to close, without this on each actuated vehicle part provide additional security devices, such as a anti-trap device in the window frame.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.In the drawing, an embodiment of the invention is shown.
Die einzige Figur zeigt schematisch den prinzipiellen Aufbau der erfindungsgemäßen Fernbedieneinrichtung. Kernstück sind ein tragbarer Sender/Empfänger (i.f. Transponder genannt) 1 sowie ein stationärer Transponder 2, der in einem in Draufsicht schematisch gezeigtem Kraftfahrzeug 3 angeordnet ist. Der Transponder 1 besitzt einen nicht dargestellten Sender für ein codiertes Betätigungs-Signal sowie einen ebenfalls nicht gezeigten Empfänger für ein vorzugsweise codiertes Frage-signal.The single figure shows schematically the basic structure of the remote control device according to the invention. The centerpiece is a portable transmitter / receiver (i.f. transponder called) 1 and a stationary transponder 2, which is arranged in a motor vehicle 3 shown schematically in plan view. The transponder 1 has a transmitter, not shown, for a coded actuation signal and a likewise not shown receiver for a preferably coded question signal.
Der Transponder 2 besitzt einen Sender für das Frage-Signal sowie einen Empfänger für das Bediensignal.The transponder 2 has a transmitter for the question signal and a receiver for the operating signal.
Mit Hilfe der im Folgenden näher erläuterten Fernbedieneinrichtung ist es möglich, Fahrzeugeinrichtung wie z. B. ein Schiebedach (nicht dargestellt) zu betätigen. Dabei führt die Fahrzeugeinrichtung eine Bewegung aus, die mehrere Sekunden dauert. Der Bediener befindet sich dabei in einer Entfernung von wenigen Metern vom Fahrzeug und gibt währenddessen das Bediensignal kontinuierlich oder in regelmäßigen Abständen ab. Hierzu dient ein Tastschalter (nicht dargestellt) am Transponder 1 , der durch den Benutzer bewusst betätigt wird.With the help of the remote control device explained in more detail below, it is possible to vehicle equipment such. B. a sunroof (not shown) to operate. The vehicle device executes a movement that lasts several seconds. The operator is located at a distance of a few meters from the vehicle and meanwhile gives the operating signal continuously or at regular intervals. For this purpose, a push-button switch (not shown) on the transponder 1, which is deliberately actuated by the user.
Als Voraussetzung für die Abgabe des Bediensignals dient ein vom Fahrzeug kontinuierlich oder in zeitlich regelmäßigen Abständen ausgesandtes Fragesignal, das der Transponder 2 nur aussendet, wenn er gleichzeitig das Bediensignal vom Transponder 1 empfängt.As a prerequisite for the delivery of the operating signal used by the vehicle continuously or at regular intervals emitted question signal that transmits the transponder 2 only when he receives the operating signal from the transponder 1 at the same time.
Bedingt durch die vorgegebene Reichweite von nur wenigen Metern für den im Transponder 2 enthaltenen Sender für das Fragesignal ergibt sich eine ständige Kontrolle des Bewegungsvorgangs für die Fahrzeugeinrichtung. Die Reichweite wird durch die Sendereichweite der in den Türaußengriffen 3 eingebauten Sendeantennen (nicht dargestellt) bestimmt. Verlässt der Benutzer mit dem Transponder 1 die genau definierte Sendereichweite der Sendeantennen und empfängt damit kein Fragesignal mehr von diesen Antennen, so wird die Abgabe des Bediensignals durch eine entsprechende Schaltungsmaßnahme innerhalb des Transponders 1 gestoppt. Der Transponder 1 meldet also durch Abgabe desDue to the predetermined range of only a few meters for the transmitter contained in the transponder 2 for the question signal results in a constant control of the movement process for the vehicle device. The range is determined by the transmission range of built in the outside door handles 3 transmit antennas (not shown). Leaves the user with the transponder 1, the well-defined transmission range of the transmit antennas and thus receives no question signal more of these antennas, the delivery of the control signal is stopped by a corresponding circuit measure within the transponder 1. The transponder 1 thus reports by delivery of the
Bediensignals dem Fahrzeug bei betätigtem Tastschalter immer zurück, ob er von den Sendeantennen das Fragesignal empfängt oder nicht. Wenn nicht wird dieOperating signal to the vehicle with the push button pressed always back whether he receives the question signal from the transmit antennas or not. If not the will
Bewegung der Fahrzeugeinrichtung gestoppt.Movement of the vehicle equipment stopped.
Bei einem zeitlichen Abstand der nacheinander ausgesandten Fragesignale von 450 ms vergehen bei Verlassen des Bereiches ebenfalls 450 ms. Das Stoppen der Bewegung der Fahrzeugeinrichtung erfolgt damit ebenfalls nach dieser Zeit.At a time interval of the consecutively transmitted question signals of 450 ms also pass 450 ms when leaving the area. Stopping the movement of the vehicle device is thus also after this time.
Konkret bedeutet dies, dass die Bewegung unter der Annahme, dass sich der Bediener schnell vom Fahrzeug entfernt, in jedem Fall nach 450 ms stoppt. Der Bediener befindet sich dabei maximal in einem Abstand von wenigen Metern vom Fahrzeug entfernt.Concretely, this means that the movement always stops after 450 ms, assuming that the operator leaves the vehicle quickly. The operator is at a maximum distance of a few meters from the vehicle.
Lässt der Bediener den Tastschalter los, so wird die Bewegung bei einem angenommenen zeitlichen Abstand der nacheinander ausgesandten Bediensignale von 100 ms schlechtestenfalls nach 100 ms gestoppt. If the operator releases the push-button switch, the movement is stopped after an assumed time interval of successively transmitted operating signals of 100 ms, or at worst after 100 ms.
