Description
Die Erfindung betrifft eine Parksperrvorrichtung für Kraftfahrzeuge nach dem Oberbegriff des Patentanspruchs 1 sowie ein Verfahren zur Aktivierung und Deaktivierung einer Parksperrvorrichtung gemäß dem Patentanspruch 10.The invention relates to a parking lock device for motor vehicles according to the preamble of patent claim 1 and to a method for activating and deactivating a parking lock device according to
Eine solche Parksperrvorrichtung findet bekanntermaßen in einem automatischen Getriebe für Kraftfahrzeuge Anwendung. Zum Einlegen einer Parksperre kann ein Getriebeschalthebel in eine Parkposition verbracht werden, wodurch ein Sperrglied in ein, beispielsweise auf einer Getriebeabtriebswelle angeordnetes Parksperrenrad greift.Such a parking lock device is known to be used in an automatic transmission for motor vehicles application. To insert a parking brake, a gearshift lever can be moved to a parking position, whereby a locking member engages in a, for example, arranged on a transmission output shaft Parksperrenrad.

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 object of the invention is to provide a parking lock device for motor vehicles or a method for activating and deactivating a parking lock device, in which the operability of the parking lock is increased.
Die Aufgabe ist durch eine Parksperrvorrichtung mit den Merkmalen des Patentanspruches 1 oder durch ein Verfahren mit den Merkmalen des Patentanspruches 10 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den jeweiligen Unteransprüchen offenbart.The object is achieved by a parking lock device with the features of claim 1 or by a method having the features of
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 part of claim 1, the locking member of the parking device is associated with an auxiliary locking element, which automatically moves after the failure of the power supply in a locked position in which it secures the already released by the control device locking member in its retracted unlocked position. In this way, the parking brake is not automatically activated after a failure of the hydraulic and / or electrical on-board system and accordingly the vehicle is not automatically blocked. Rather, the auxiliary locking element retains the already released by the control device locking member in its unlocked position.
Bevorzugt kann erst durch ein aktives Eingreifen des Fahrers, d. h. durch manuelle Betätigung das Hilfsriegelelement das Sperrglied freigeben.Preferably can only by an active intervention of the driver, d. H. by manual operation, 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 be actuated by means of an auxiliary energy device which is independent of the electrical system of the vehicle. In this way, the auxiliary locking element can be actuated even with a total failure of the electrical system using the separate auxiliary power device.
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 technically simple and reliable provision of the auxiliary power, the auxiliary power in the auxiliary power device user side, d. H. by the driver. In this case, can be dispensed with an additional separate auxiliary power source.
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 is generated for actuating the locking element. In this case, the auxiliary latch member may be exemplarily electromagnetically driven by the auxiliary power device to be adjusted after the failure of the power supply in the locked position.
Für eine einfache Erzeugung der elektrischen Hilfsenergie kann bevorzugt ein Piezoelement eingesetzt werden, das bei manueller Druckbetätigung elektrischen Strom erzeugt, der wiederum ein dem Hilfsriegelelement zugeordnetes Elektromagnet anregt.For a simple generation of the auxiliary electric power, a piezoelectric element can preferably be used, which generates electrical current upon manual pressure actuation, which in turn excites an electromagnet associated with the auxiliary latching 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 Hilfsenergieeinrichtung auch hydraulische und/oder pneumatische Energie zur Betätigung des Hilfsriegelelements bereitstellen.For reasons of comfort, the auxiliary energy device can have an operating element for the driver, which is arranged in the vehicle interior. In this case, the control element may be a separate parking lock button or be integrated in a transmission shift lever. Therefore, if after the failure of the electrical system according to the invention, the parking brake is to be inserted, the above-mentioned control is actively operated by the driver to spend the auxiliary locking element of the invention in its release position. Instead of or in addition to the auxiliary electrical energy, the auxiliary power device can also provide hydraulic and / or pneumatic energy for actuating the auxiliary latch element.
Im Unterschied zu der oben erwähnten Notfallsituation, d. h. dem Ausfall der Energieversorgung, steuert im Normalbetrieb des Bordnetzes des Fahrzeugs die Steuereinrichtung das Hilfsriegelelement beispielsweise elektronisch an, 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 emergency situation mentioned above, d. H. the failure of the power supply, controls in normal operation of the electrical system of the vehicle, the control device, the auxiliary locking element, for example, electronically 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, after the failure of the power supply, the locking member released by the control device for an adjustment into the locking position can still be secured in its unlocking position by the auxiliary locking element. This prevents that after the failure of the power supply, the parking brake is automatically inserted without this being prevented by the driver.
