Aus der
Die
Der Erfindung liegt die Aufgabe zugrunde ein Verfahren und eine Vorrichtung zum Starten eines Verbrennungsmotors anzugeben, mit welchen trotz Kostenreduzierung ein zuverlässiger Start des Verbrennungsmotors in allen Situationen möglich ist.The invention is based on the object of specifying a method and a device for starting an internal combustion engine with which a reliable start of the internal combustion engine is possible in all situations despite the cost reduction.
Die Aufgabe wird durch den Gegenstand des Anspruch 1 gelöst.The object is achieved by the subject matter of claim 1.
Bei einem Verfahren zum Start eines Verbrennungsmotors mittels eines Riementriebes mit einem Riemenstartergenerator in einem Fahrzeug, bei welchem der Riemenstartergenerator zum Antrieb eines Riemens des Riementriebes bestromt wird und ein Drehmoment des Riemens auf eine mit dem Verbrennungsmotor gekoppelten Kurbelwelle übertragen wird, wird zum Start des Verbrennungsmotors mindestens ein Parameter des Riemenstartergenerators temperaturabhängig eingestellt. Dies hat den Vorteil, dass ein Schlüsselstart des Verbrennungsmotors, unter welchem im Weiteren ein Erststart oder ein Kaltstart des Verbrennungsmotors verstanden werden soll, über den Riementrieb erfolgen kann. Auf einen Ritzelstarter kann somit verzichtet werden. Dadurch wird der vom Verbrennungsmotor benötigte Bauraum bei einer gleichzeitigen Gewichtseinsparung verringert. Neben einer Kostenreduzierung wird die Getriebeglocke und der Zahnkranz des Zweimassenschwungrades vereinfacht. Letzteres insbesondere deshalb, weil keine Kraftübertragung über diesen notwendig ist. Auch besteht ein Einsparungspotential bei der elektrischen Verkabelung.In a method for starting an internal combustion engine by means of a belt drive with a belt starter generator in a vehicle, in which the belt starter generator is energized to drive a belt of the belt drive and a torque of the belt is transmitted to a crankshaft coupled to the internal combustion engine, to start the internal combustion engine at least a parameter of the belt starter generator set as a function of temperature. This has the advantage that a key start of the internal combustion engine, which in the following is to be understood as an initial start or a cold start of the internal combustion engine, can take place via the belt drive. There is therefore no need for a pinion starter. This reduces the installation space required by the internal combustion engine while at the same time saving weight. In addition to reducing costs, the bell housing and the ring gear of the dual-mass flywheel are simplified. The latter in particular because no power transmission via this is necessary. There is also potential for savings in electrical wiring.
In einer Ausführungsform wird der mindestens eine Parameter des Riemenstartergenerators in Abhängigkeit von einer Temperatur des Verbrennungsmotors eingestellt. Damit wird gewährleistet, dass bei jeder Temperatur des Verbrennungsmotors ein entsprechendes Losbrechmoment von dem Riementrieb auf den Verbrennungsmotors übertragen werden kann, um diesen zu starten.In one embodiment, the at least one parameter of the belt starter generator is set as a function of a temperature of the internal combustion engine. This ensures that at any temperature of the internal combustion engine, a corresponding breakaway torque can be transmitted from the belt drive to the internal combustion engine in order to start it.
In einer weiteren Ausführungsform wird der mindestens eine Parameter des Riemenstartergenerators in Abhängigkeit von einer Temperator des Verbrennungsmotors eingestellt, wenn eine Differenz zwischen der Temperatur des Verbrennungsmotors und einer Umgebungstemperatur des Fahrzeuges einen vorgegebenen Differenzschwellwert überschreitet. Diese Bedingung lässt sich softwaremäßig einfach detektieren.In a further embodiment, the at least one parameter of the belt starter generator is set as a function of a temperature of the internal combustion engine if a difference between the temperature of the internal combustion engine and an ambient temperature of the vehicle exceeds a predetermined difference threshold value. This condition can be easily detected using the software.
In einer weiteren Ausführungsform wird in Abhängigkeit von der jeweiligen Temperatur des Verbrennungsmotors der mindestens eine Parameter des Riemenstartergenerators variabel, vorzugsweise gestaffelt, angepasst. Dabei können lineare oder nichtlineare Zusammenhänge zwischen der Motortemperatur und der Umgebungstemperatur berücksichtigt werden.In a further embodiment, the at least one parameter of the belt starter generator is variably, preferably staggered, adapted as a function of the respective temperature of the internal combustion engine. Linear or non-linear relationships between the motor temperature and the ambient temperature can be taken into account.
In einer weiteren Ausführungsform wird bei Unterschreitung einer ersten vorgegebenen Temperatur des Verbrennungsmotors der mindestens eine Parameter des Riemenstartergenerators erhöht bzw. abgesenkt und bei Unterschreitung einer zweiten vorgegebenen Temperatur des Verbrennungsmotors, welche kleiner ist als die erste vorgegebene Temperatur, weiter erhöht oder abgesenkt. Somit ist eine gestaffelte Anpassung einfach ausführbar.In a further embodiment, if the internal combustion engine falls below a first predetermined temperature, the at least one parameter of the belt starter generator is increased or decreased, and if the internal combustion engine falls below a second predetermined temperature, which is lower than the first predetermined temperature, it is increased or decreased further. A staggered adjustment can thus be easily carried out.
In einer weiteren Ausführungsform wird der Riemenstartergenerator impulsförmig angesteuert. Dies ist insbesondere bei sehr tiefen Temperauren des Verbrennungsmotors von Vorteil, da das Motorlosbrechmoment schnell überwunden und eine Drehzahl des Verbrennungsmotors aufgebaut werden kann.In a further embodiment, the belt starter generator is activated in the form of a pulse. This is particularly advantageous at very low temperatures of the internal combustion engine, since the engine breakaway torque can be overcome quickly and a speed of the internal combustion engine can be built up.
In einer weiteren Ausführungsform wird der Riemenstartergenerator mit einer wechselnden Bestromungsrichtung angesteuert. Damit wird ein zuverlässiges Losbrechen des Verbrennungsmotors und der Aufbau seiner Drehzahl gewährleistet.In a further embodiment, the belt starter generator with an alternating Direction of current flow controlled. This ensures a reliable breakaway of the internal combustion engine and the build-up of its speed.
In einer weiteren Ausführungsform wird auf dem Riementrieb bei Stillstand des Verbrennungsmotors ein vorgegebenes Drehmoment zeitlich definiert aufgebracht, das kleiner ist als ein zum Starten des Verbrennungsmotors erforderliches Drehmoment. Dieser Schritt kann als Justierverfahren vor dem eigentlichen Start des Verbrennungsmotors durchgeführt werden, um sicherzustellen, dass Freiwinkel der verschiedenen Komponenten des Riementriebs überwunden werden. Durch die Überwindung dieser Freiwinkel wird der komplette Riementrieb so verspannt, dass ein Startmoment für die Kurbelwelle des Verbrennungsmotors immer unter gleichen Bedingungen aufgebracht werden kann.In a further embodiment, when the internal combustion engine is at a standstill, a predetermined torque is applied in a defined time manner to the belt drive, which torque is less than a torque required to start the internal combustion engine. This step can be carried out as an adjustment process before the internal combustion engine is actually started in order to ensure that the clearance angles of the various components of the belt drive are overcome. By overcoming this clearance angle, the entire belt drive is tensioned in such a way that a starting torque for the crankshaft of the internal combustion engine can always be applied under the same conditions.
In einer weiteren Ausführungsform wird bei der temperaturabhängigen Anpassung des mindestens einen Parameters des Riemenstartergenerators ein Schlüsselstart des Verbrennungsmotors ausgeführt, während bei Überschreitung der ersten vorgegebenen Temperatur des Verbrennungsmotors eine Start-Stopp-Automatik aktiviert wird. Der Riementrieb kann somit für alle im Fahrzeug vorgesehenen Startsituationen des Verbrennungsmotors genutzt werden.In a further embodiment, a key start of the internal combustion engine is carried out during the temperature-dependent adaptation of the at least one parameter of the belt starter generator, while an automatic start-stop system is activated when the first predetermined temperature of the internal combustion engine is exceeded. The belt drive can thus be used for all starting situations of the internal combustion engine provided in the vehicle.
Ein weiterer Aspekt der Erfindung betrifft eine Vorrichtung zum Start eines Verbrennungsmotors in einem Fahrzeug, umfassend einen Riementrieb mit einem Riemenstartergenerator, der über einen Riemen mit einer Kurbelwelle des Verbrennungsmotor koppelbar ist, wobei der Riemenstartergenerator eine Steuereinheit aufweist. Bei dieser Vorrichtung ist die Steuereinheit zur Durchführung eines Verfahrens nach mindestens einem in dieser Schutzrechtsanmeldung beschriebenen Merkmal ausgebildet.Another aspect of the invention relates to a device for starting an internal combustion engine in a vehicle, comprising a belt drive with a belt starter generator, which can be coupled to a crankshaft of the internal combustion engine via a belt, the belt starter generator having a control unit. In this device, the control unit is designed to carry out a method according to at least one feature described in this patent application.
