Gemäß den
Die Aufgabe der Erfindung besteht darin, eine Parksperrvorrichtung für Kraftfahrzeuge oder ein Verfahren zur Aktivierung und Deaktivierung einer Parksperrvorrichtung bereit zu stellen, bei der die Bedienbarkeit der Parksperre erhöht ist.The The object of the invention is a parking lock device for motor vehicles or a method for activating and deactivating a parking lock device to provide, in which the operability of the parking brake is increased.
Die Aufgabe ist durch die Merkmale des Patentanspruches 1 oder des Patentanspruches 11 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den jeweiligen Unteransprüchen offenbart.The The object is achieved by the features of claim 1 or claim 11 solved. Advantageous developments of the invention are in the respective dependent claims disclosed.
Gemäß dem kennzeichnenden Teil des Patentanspruches 1 ist dem Sperrglied der Parkvorrichtung ein Hilfsriegelelement zugeordnet, das sich nach dem Ausfall der Energieversorgung selbsttätig in eine Sperrposition bewegt, in der es das von der Steuereinrichtung bereits freigegebene Sperrglied in seiner zurückgezogenen Entriegelungsposition sichert. Auf diese Weise wird nach einem Ausfall des hydraulisch und/oder elektrischen Bordsystems die Parksperre nicht automatisch aktiviert und entsprechend das Fahrzeug nicht automatisch blockiert. Vielmehr hält das Hilfsriegelelement das bereits von der Steuereinrichtung freigegebene Sperrglied noch in seiner Entriegelungsposition zurück.According to the characterizing one Part of claim 1 is the locking member of the parking device associated with an auxiliary locking element, which after the failure of Energy supply automatically in moves a locking position in which it by the control device already released locking member in its retracted unlocking position guaranteed. In this way, after a failure of the hydraulic and / or electric on-board system the parking brake is not automatic activated and accordingly the vehicle is not blocked automatically. Much more Hold that Auxiliary locking element already released by the control device Locking member still in its unlocked position back.
Bevorzugt kann erst durch ein aktives Eingreifen des Fahrers, d. h. durch manuelle Betätigung das Hilfsriegelelement das Sperrglied freigeben.Prefers can only be activated by an active intervention of the driver, i. H. by manual actuation of the Auxiliary locking element release the locking member.
Das Hilfsriegelelement kann bevorzugt mittels einer vom Bordnetz des Fahrzeugs unabhängigen Hilfsenergieeinrichtung betätigt werden. Auf diese Weise kann das Hilfsriegelelement auch bei einem Totalausfall des Bordnetzes mit Hilfe der separaten Hilfsenergieeinrichtung betätigt werden.The Auxiliary locking element can preferably by means of a from the electrical system of Vehicle independent Auxiliary power operated become. In this way, the auxiliary locking element even in a total failure of the electrical system using the separate auxiliary power device are operated.
Für eine technisch einfache und zuverlässige Bereitstellung der Hilfsenergie kann in der Hilfsenergieeinrichtung die Hilfsenergie benutzerseitig, d. h. vom Fahrer, erzeugt werden. In diesem Fall kann auf eine zusätzliche separate Hilfsenergiequelle verzichtet werden.For a technical simple and reliable Provision of auxiliary power may be in the auxiliary power device the auxiliary power user side, d. H. by the driver. In this case, can on an additional separate auxiliary power source can be dispensed with.
Für eine einfache und komfortable Betätigung des Hilfsriegelelements ist es von Vorteil, wenn mittels der Hilfsenergieeinrichtung elektrische Energie zur Betätigung des Riegelelements erzeugt wird. In diesem Fall kann das Hilfsriegelelement beispielhaft elektromagnetisch von der Hilfsenergieeinrichtung ansteuerbar sein, um nach dem Ausfall der Energieversorgung in die Sperrposition verstellt zu werden.For a simple and comfortable operation of the auxiliary locking element, it is advantageous if by means of the auxiliary power device electrical energy for actuation of the locking element is generated. In this case, the auxiliary locking element exemplarily electromagnetically controlled by the auxiliary power device be in the blocking position after the failure of the power supply to be displaced.
Für eine einfache Erzeugung der elektrischen Hilfsenergie kann bevorzugt ein Piezoelement eingesetzt werden, dass bei manueller Druckbetätigung elektrischen Strom erzeugt, der wiederum ein dem Hilfsriegelelement zugeordnetes Elektromagnet anregt.For a simple Generation of the auxiliary electrical energy may preferably be a piezoelectric element used be that generates electrical current with manual pressure actuation, which, in turn, excites an electromagnet associated with the auxiliary latch element.
Die Hilfsenergieeinrichtung kann aus Komfortgründen ein Bedienelement für den Fahrer aufweisen, dass im Fahrzeuginnenraum angeordnet ist. Dabei kann das Bedienelement ein separater Parksperrentaster sein oder in einem Getriebeschalthebel integriert sein. Wenn daher nach dem Ausfall des elektrischen Bordnetzes erfindungsgemäß die Parksperre eingelegt werden soll, so ist das oben erwähnte Bedienelement aktiv vom Fahrer zu betätigen, um das erfindungsgemäße Hilfsriegelelement in seine Freigabeposition zu verbringen. Anstelle von bzw. zusätzlich zu der elektrischen Hilfsenergie kann die Hilfs energieeinrichtung auch hydraulische und/oder pneumatische Energie zur Betätigung des Hilfsriegelelements bereitstellen.The Auxiliary power device can be a control element for the driver for reasons of comfort have, that is arranged in the vehicle interior. It can the control be a separate parking lock button or in one Gear shift lever be integrated. If therefore after the failure of the electrical system according to the invention, the parking brake engaged should be, so is the above-mentioned Actively active operating by the driver to the inventive auxiliary locking element to spend in his release position. Instead of or in addition to the auxiliary electric power, the auxiliary energy device also hydraulic and / or pneumatic energy for actuating the Provide auxiliary latch element.
Im Unterschied zu der oben erwähnten Notfallsituation, d. h. dem Ausfall der Energieversorgung, kann im Normalbetrieb des Bordnetzes des Fahrzeugs die Steuereinrichtung das Hilfsriegelelement beispielsweise elektronisch ansteuern, um es in seiner Freigabeposition zu halten, und zwar unabhängig von einer Betätigung des den Hilfsriegelelement zugeordnetem Bedienelements. Dadurch ist ein im Normalbetrieb freies Verstellen des Sperrglieds in seine Verriegelungsposition gewährleistet.In contrast to the above-mentioned emergency situation, ie the failure of Energieversor tion, in normal operation of the electrical system of the vehicle, the control device, the auxiliary locking element, for example, electronically control to hold it in its release position, regardless of an operation of the auxiliary locking element associated control element. This ensures a free operation in normal operation of the locking member in its locking position.
Wie aus der Vorbeschreibung hervorgeht, kann erfindungsgemäß nach dem Ausfall der Energieversorgung das von der Steuereinrichtung für eine Verstellung in die Verriegelungsposition freigegebene Sperrglied durch das Hilfsriegelelement noch in seiner Entriegelungsposition gesichert werden. Dadurch ist verhindert, dass nach dem Ausfall der Energieversorgung die Parksperre automatisch eingelegt wird, ohne dass dies vom Fahrer verhindert werden kann.As can be seen from the above description, according to the invention according to the Failure of the power supply from the control device for an adjustment in the locking position released locking member by the auxiliary locking element be secured in its unlocked position. This is prevents the parking brake after the failure of the power supply is automatically inserted without this being prevented by the driver can be.
