Description

Stand der TechnikState of the art

Aus DE 199 56 384 C1 ist ein Impulsstartverfahren und eine Impulsstartvorrichtung für eine Brennkraftmaschine bekannt. Gemäß des in DE 199 56 384 C1 offenbarten Impulsstartverfahrens wird während einer Beschleunigungsphase eine Schwungmasse drehangetrieben beschleunigt und anschließend während einer Kupplungsphase die drehende Schwungmasse mit einer drehbar gelagerten Welle, vorzugsweise der Kurbelwelle der Verbrennungskraftmaschine zur Drehmomentübertragung gekuppelt. Während der Aufziehphase und/oder der Kupplungsphase wird der Drehzahlverlauf der Schwungmasse ausgewertet und aus dieser Auswertung abgeleitet, ob ein erfolgreicher Start der Brennkraftmaschine möglich ist. Falls ein erfolgreicher Start nicht zu erwarten steht, wird die Brennkraftmaschine über die Welle in eine für einen nachfolgenden zweiten Startversuch günstige Betriebsstellung gebracht. Gemäß des aus DE 199 56 384 C1 bekannten Impulsstartverfahrens wird während der Aufziehphase für die Auswertung der Gradient des Drehzahlverlaufes der Schwungmasse verwendet und bei zu geringen Gradienten die Kupplungsphase eingeleitet.Out DE 199 56 384 C1 For example, a pulse starting method and a pulse starting device for an internal combustion engine are known. According to the in DE 199 56 384 C1 During an acceleration phase, a pulsating mass is rotationally driven accelerated and then coupled during a coupling phase, the rotating flywheel with a rotatably mounted shaft, preferably the crankshaft of the internal combustion engine for torque transmission. During the winding phase and / or the coupling phase of the speed curve of the flywheel is evaluated and derived from this evaluation, whether a successful start of the internal combustion engine is possible. If a successful start is not to be expected, the internal combustion engine is brought via the shaft in a favorable for a subsequent second attempt to start operating position. According to the DE 199 56 384 C1 Known impulse start method is used during the winding phase for the evaluation of the gradient of the speed curve of the flywheel and initiated at low gradient, the coupling phase.

Bei derzeit auf dem Markt befindlichen Fahrzeugen mit Hybridantrieb mit einem Verbrennungsmotor und mindestens einem Elektroantrieb, besteht für den Fahrer keine Möglichkeit, bei entladener Hochvoltbatterie das Fahrzeug zu starten. Dies stellt einen höchst unbefriedigenden Zustand dar.at currently on the market vehicles with hybrid drive with an internal combustion engine and at least one electric drive, There is no possibility for the driver discharged high-voltage battery to start the vehicle. This constitutes one most unsatisfactory condition.

Offenbarung der ErfindungDisclosure of the invention

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Möglichkeit zu schaffen, um ein mit einem Hybridantrieb ausgestattetes Fahrzeug entweder über die das Bordnetz speisende Fahrzeugbatterie oder fremd zu starten.Of the present invention is based on the object, a possibility to create a vehicle equipped with a hybrid drive either via the vehicle battery supplying the vehicle electrical system or to start someone else.

Erfindungsgemäß wird ein Verfahren und eine Vorrichtung vorgeschlagen, die es ermöglicht, insbesondere bei entladener Hochvoltbatterie, aus dem Niedervoltnetz, dem eine Bordnetz-Batterie des Kraftfahrzeuges zugeordnet ist, bei der es sich im allgemeinen um eine 12-Volt Batterie handelt, Energie in das Hochvoltnetz zu übertragen, wobei zwischen dem Niedervoltnetz und dem Hochvoltnetz ein DC/DC-Wandler geschaltet ist. Am Hochvoltnetz ist der mindestens eine Elektroantrieb des Hybridantriebs sowie eine Hochvoltbatterie angeschlossen. Der DC/DC-Wandler kann die niedrigere Niedervoltnetzspannung auf die höhere Spannung des elektrischen Antriebs des Hybridantrieb anheben. Zur Versorgung des elektrischen Antriebs ist eine Hochvoltbatterie vorgesehen. Ein Energieaustausch mit dem Niedervoltnetz, kann über den DC/DC-Wandler, insbesondere bidirektional, erfolgen. Die Hochvoltbatterie kann über ein Schütz ein- bzw. weggeschaltet werden. Für den elektrischen Antrieb ist eine elektrische Maschine vorgesehen, die über einen Umrichter, insbesondere Pulswechselrichter, und einen Zwischenkreiskondensator zugeschaltet ist. Die elektrische Maschine wird auch als Starter für den Verbrennungsmotor verwendet. Der mindestens eine Elektroantrieb des Hybridantriebes des Kraftfahrzeuges verfügt über eine Kupplung zum anderen Antriebsaggregat, insbesondere Verbrennungsmotor, des Kraftfahrzeuges. Reicht die Ladung der Hochvoltbatterie für einen Start des Verbrennungsmotors nicht mehr aus, wird Energie aus dem Niedervoltnetz über den DC/DC-Wandler in das Hochvoltnetz übertragen und anschließend ein Impulsstart durchgeführt. Für den Impulsstart wird die elektrische Maschine bei abgekuppelten Verbrennungsmotor beschleunigt. Vorzugsweise wird der Elektroantrieb durch die im Hochvoltnetz vorhandene Energie beschleunigt. Vorzugsweise wird die Maschine bis zu der maximal entsprechend dem Ladungsniveau der Fahrzeugbatterie erreichbaren Drehzahl beschleunigt. Anschließend wird die Verbrennungskraftmaschine durch den beschleunigten Elektroantrieb gestartet.According to the invention a method and a device proposed, which makes it possible, in particular with discharged high-voltage battery, from the low-voltage network, the one Wiring battery of the motor vehicle is assigned, in which it is generally a 12-volt battery, energy in to transmit the high-voltage network, between the low-voltage network and the high-voltage network, a DC / DC converter is connected. At the high voltage network is the at least one electric drive of the hybrid drive as well a high-voltage battery connected. The DC / DC converter can use the lower low voltage mains voltage to the higher voltage lift the electric drive of the hybrid drive. To the supply the electric drive is a high-voltage battery provided. An energy exchange with the low-voltage network, can over the DC / DC converter, in particular bidirectional, take place. The high-voltage battery can be switched on or off via a contactor. For the electric drive is an electric machine provided by a converter, in particular pulse inverter, and a DC link capacitor is switched on. The electric Machine is also called a starter for the internal combustion engine used. The at least one electric drive of the hybrid drive of the motor vehicle has a clutch on the other drive unit, in particular internal combustion engine, the Motor vehicle. Is sufficient for the charge of the high-voltage battery for A start of the internal combustion engine is no longer enough, becomes energy transferred from the low-voltage network via the DC / DC converter in the high-voltage network and then a pulse start performed.
