Description

Das erfindungsgemäße Verfahren betrifft die Notwendigkeit einen geschlossenen Kofferraum eines Kraftfahrzeuges zu entriegeln, wenn beispielsweise eine Person darin eingeschlossen ist. Aus der EP 1 041 228 ist es bereits bekannt, im Kofferraum eine Notentriegelung vorzusehen. In Abhängigkeit des Signals von ebenfalls im Kofferraum angebrachten Detektoren wird so eine eingeschlossene Person erkannt und die Notentriegelung freigeschaltet. Als Detektor kann ein Bewegungssensor verwendet werden.The inventive method relates to the need to unlock a closed trunk of a motor vehicle, for example, if a person is included therein. From the EP 1 041 228 It is already known to provide an emergency release in the trunk. Depending on the signal of also mounted in the trunk detectors so a trapped person is detected and unlocked the emergency release. As a detector, a motion sensor can be used.

Eine solche Anordnung ist bei der weit verbreiteten Anordnung des Kofferraumes im Heck eines Kraftfahrzeuges ohne Probleme einsetzbar.Such an arrangement can be used without problems in the widespread arrangement of the trunk in the rear of a motor vehicle.

Dagegen ist eine einfache Entriegelung der Kofferraumhaube bei Fahrzeugen, deren Kofferraum im Bug des Fahrzeuges angeordnet ist, wenn das Fahrzeuges sich in Bewegung befindet, gefährlich, da die Kofferraumhaube bei einer Entriegelung während der Fahrt sofort aufspringen und dem Fahrer die Sicht versperren würde.In contrast, a simple release of the boot lid in vehicles whose trunk is located in the bow of the vehicle when the vehicle is in motion, dangerous, since the boot lid jump open at a release while driving and the driver would block the view.

Mit der vorliegenden Erfindung wird sichergestellt, daß nach dem Betätigen eines Entriegelungsgriffes im Inneren des Kofferraumes die Kofferraumhaube nicht unkontrolliert während der Fahrt aufspringt. Besonders vorteilhaft ist es, bei Betätigung eines Entriegelungsgriffes im Inneren des Kofferraums die Geschwindigkeit des Fahrzeuges zu erfassen und das Stellelement zum Lösen eines Fanghakens der Kofferraumhaube nur dann anzusteuern, wenn das Fahrzeug steht, d.h. wenn die Fahrgeschwindigkeit v = 0 ist.With the present invention it is ensured that after pressing an unlocking handle in the interior of the trunk, the trunk lid does not jump uncontrollably while driving. It is particularly advantageous to detect the speed of the vehicle upon actuation of an unlocking handle in the interior of the boot and to actuate the actuating element for releasing a catch hook of the boot lid only when the vehicle is stationary, i. when the vehicle speed v = 0.

Befindet sich das Fahrzeug in Fahrt wird mit dem Betätigen des Entriegelungsgriffes eine vorgebbare Verzögerungszeit gestartet und das Stellelementes zum Lösen des an der Kofferraumhaube angreifenden Fanghakens erst nach Ablauf der Verzögerungszeit betätigt. Vorteilhafterweise erfolgt gleichzeitig mit dem Starten der vorgebbaren Verzögerungszeit noch eine Fahrersituation. Damit hat der Fahrer genug Zeit, das Fahrzeug anzuhalten und so ein Versperren der Sicht für den Fahrer beim Aufspringen der Kofferraumhaube zu verhindern.If the vehicle is in motion, a predeterminable delay time is started with the actuation of the unlocking handle, and the actuating element for releasing the catch hook acting on the boot lid is actuated only after the delay time has elapsed. Advantageously, takes place simultaneously with the start of the predefinable Delay time still a driver situation. This gives the driver enough time to stop the vehicle and thus prevent the driver from blocking the view when the boot lid opens.

Vorteilhafte Weiterbildungen und Maßnahmen sind in den Unteransprüchen aufgeführt.Advantageous developments and measures are listed in the subclaims.

So ist es vorteilhaft, den im Inneren des Kofferraumes befindlichen Entriegelungsgriff selbstleuchtend zu gestalten oder ihn aktiv zu beleuchten. Für eine selbstleuchtende Ausführung kann auf den Entriegelungsgriff eine fluoreszierende Schicht aufgebracht werden, welche beim Schließen des Kofferraumes nachleuchtet. Für eine aktive Beleuchtung kann die Kofferraumbeleuchtung so ausgelegt und angesteuert sein, daß sie beim Schließen der Kofferraumhaube für eine einstellbare Zeit nachleuchtet.Thus, it is advantageous to make the inside of the trunk located unlocking handle self-luminous or to actively illuminate it. For a self-luminous design, a fluorescent layer can be applied to the unlocking handle, which luminesces when closing the trunk. For active lighting, the trunk lighting can be designed and controlled so that it luminesces when closing the trunk lid for an adjustable time.

Eine optische und/oder akustische Fahrerinformation, die bei Betätigung des Entriegelungsgriffes ausgelöst wird, stellt sicher daß dem Fahrer bis zum Ablauf der Verzögerungszeit genug Zeit verbleibt, um das Fahrzeug anzuhalten und so eine gefährliche Situation beim Öffnen der Kofferraumhaube zu vermeiden.An optical and / or acoustic driver information, which is triggered upon actuation of the release handle, ensures that the driver until the end of the delay time enough time remains to stop the vehicle and to avoid a dangerous situation when opening the trunk lid.

Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert.Embodiments of the invention are illustrated in the drawings and explained in more detail in the following description.

In Fig. 1 ist mit dem Bezugszeichen 10 der im Inneren des Kofferraumes angeordnete Entriegelungsgriff dargestellt, wobei hier lediglich auf eine Prinzipdarstellung ohne räumliche Anordnung eingegangen wird. Der Entriegelungsgriff 10 ist mit dem Steuergerät SG verbunden. Beim Betätigen des Entriegelungsgriffes wird ein Mikroschalter betätigt und der Kontakt wird im Steuergerät als Signal für die Betätigung des Entriegelungsgriffes erfaßt. Parallel zu dem Signal des Entriegelungsgriffes wird im Steuergerät SG das Signal der Geschwindigkeit v des Fahrzeuges erfaßt. In der Figur ist dies symbolisch durch das Bezugszeichen 11 angegeben. Das Steuergerät SG wertet diese Signale aus und steuert bei Vorliegen entsprechender Bedingungen, die im weiteren in Zusammenhang mit Figur 2 erläutert werden, ein Stellelement 12 an, welches dann eine Freigabe des Fanghakens für die Kofferraumhaube 13 bewirkt.In Fig. 1 is represented by the reference numeral 10 arranged in the interior of the trunk unlocking handle, which is discussed here only on a schematic diagram without spatial arrangement. The unlocking handle 10 is connected to the control unit SG. When you press the release handle is a Microswitch actuated and the contact is detected in the control unit as a signal for the actuation of the release handle. Parallel to the signal of the release handle, the signal of the speed v of the vehicle is detected in the control unit SG. In the figure, this is indicated symbolically by the reference numeral 11. The control unit SG evaluates these signals and controls in the presence of appropriate conditions, hereinafter in connection with FIG. 2 be explained, an actuating element 12, which then causes a release of the fishing hook for the trunk lid 13.

In der Fig. 2 sind die einzelnen Verfahrensschritte dargestellt. In einem ersten Schritt 20 wird der Entriegelungsgriff im Kofferraum betätigt und mit dem Verfahrensschritt 21 ein Mikroschalter betätigt, dessen Signal im Steuergerät SG erfaßt wird. Das Signal des Mikroschalters bewirkt in einem weiteren Verfahrensschritt 22, die Erfassung und Prüfung der aktuellen Geschwindigkeit des Fahrzeuges. Dieses Signal ist im Fahrzeug ohnehin vorhanden, beispielsweise für die Zündsteuerung. Wenn die aktuelle Fahrzeuggeschwindigkeit v Null ist, dann bedeutet das, daß das Fahrzeug steht und es wird im Verfahrensschritt 23 das Stellelement 12 angesteuert, so daß im Verfahrensschritt 24 der Fanghaken freigegeben wird und die Kofferraumhaube geöffnet werden kann. Wurde im Arbeitsschritt 22 eine Geschwindigkeit größer Null ermittelt, dann befindet sich das Fahrzeug in Fahrt und es wird zum einen im Verfahrensschritt 25 eine Verzögerungszeit tv gestartet und gleichzeitig im Arbeitsschritt 26 eine Information an den Fahrer ausgegeben. Die Fahrerinformation kann optisch und/oder akustisch im Fahrzeuginneren erfolgen. Der Fahrer hat nun genügend Zeit, während der Verzögerungszeit das Fahrzeug abzubremsen und zum Stehen zu bringen, so daß beim Lösen des Fanghakens nach Ablauf der Verzögerungszeit keine gefährliche Situation entsteht.In the Fig. 2 the individual process steps are shown. In a first step 20 of the unlocking handle is actuated in the trunk and operated with the method step 21, a microswitch whose signal is detected in the control unit SG. The signal of the microswitch causes in a further method step 22, the detection and testing of the current speed of the vehicle. This signal is present in the vehicle anyway, for example, for the ignition control. If the current vehicle speed v is zero, then this means that the vehicle is stationary and the actuating element 12 is activated in method step 23, so that in method step 24 the catch hook is released and the boot lid can be opened. Was determined in step 22, a speed greater than zero, then the vehicle is in motion and it is on the one hand in step 25, a delay time tv started and at the same time output in step 26 information to the driver. The driver information can be done visually and / or acoustically in the vehicle interior. The driver now has enough time during the deceleration time to decelerate the vehicle and bring it to a standstill, so that when releasing the catch hook after the delay time no dangerous situation arises.

Um den Entriegelungsgriff im Inneren des Kofferraumes leicht zu finden, kann dieser aktiv oder passiv beleuchtet ausgeführt sein. Denkbar wäre hier beispielsweise eine fluoreszierende Schicht auf der Griffoberfläche. Eine andere Möglichkeit ist die aktive Beleuchtung, beispielsweise durch Ausnutzung der Kofferrauminnenbeleuchtung.To easily find the unlocking handle inside the trunk, this can be made active or passive light. It would be conceivable here, for example, a fluorescent layer on the handle surface. Another possibility is the active lighting, for example, by exploiting the trunk interior lighting.

Desweiteren ist es möglich, die Verzögerungszeit t in Abhängigkeit von der aktuellen Geschwindigkeit des Fahrzeuges vorzugeben oder vom Fahrer einstellen zu lassen.Furthermore, it is possible to specify the delay time t as a function of the current speed of the vehicle or to be set by the driver.
