Abstract
Die Erfindung betrifft ein Verfahren zum Starten eines Verbrennungsmotors mittels eines Riementriebes und/oder eines Ritzelstarters bei vorhandenem Riemenstartergenerator in einem Kraftfahrzeug, bei welchem eine Kurbelwelle (10) des Verbrennungsmotors mit einem Riemen (3) verbunden ist. Um ein optimale und reproduzierbare Startposition im Riementrieb zu erreichen, wird auf dem Riementrieb (1) bei Stillstand des Verbrennungsmotors ein vorgegebenes Drehmoment aufgebracht, das kleiner ist als ein zum Starten des Verbrennungsmotors erforderliches Drehmoment.The invention relates to a method for starting an internal combustion engine by means of a belt drive and / or a pinion starter with available belt starter generator in a motor vehicle, in which a crankshaft (10) of the internal combustion engine with a belt (3) is connected. In order to achieve an optimal and reproducible starting position in the belt drive, a predetermined torque is applied to the belt drive (1) at standstill of the internal combustion engine, which is smaller than a torque required for starting the internal combustion engine.
Description
Die Erfindung betrifft ein Verfahren zum Starten eines Verbrennungsmotors mittels eines Riementriebes und/oder eines Ritzelstarters bei vorhandenem Riemenstartergenerator in einem Kraftfahrzeug, bei welchem eine Kurbelwelle des Verbrennungsmotors mit einem Riemen verbunden istThe invention relates to a method for starting an internal combustion engine by means of a belt drive and / or a pinion starter with existing belt starter generator in a motor vehicle, in which a crankshaft of the internal combustion engine is connected to a belt
Der Start eines Verbrennungsmotors in einem Kraftfahrzeug kann mittels eines Riemenstartergenerators oder eines Ritzelstarters erfolgen. Aus der
Bei der Verwendung eines Ritzelstarters für den Start des Verbrennungsmotors legt sich der komplette Riementrieb in die andere Richtung des Verbrennungsmotors an (Momentenumkehr), da er über die Kurbelwelle angeschleppt wird. Hier müssen ebenfalls Freiwinkel und Schleppmomente überwunden werden, insbesondere da der Ritzelstarter an einer primären Seite des Zweimassenschwungrades des Verbrennungsmotors angreift. In beiden Fällen liegen beim Start des Verbrennungsmotors variierende Ausgangsbedingungen am Riementrieb vor.When using a pinion starter for the start of the internal combustion engine, the entire belt drive puts in the other direction of the internal combustion engine (torque reversal), as it is towed over the crankshaft. Clearance angles and drag torques must also be overcome here, especially since the pinion starter acts on a primary side of the dual-mass flywheel of the internal combustion engine. In both cases, starting conditions of the internal combustion engine are varying starting conditions on the belt drive.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Starten eines Verbrennungsmotors mittels eines Riementriebes anzugeben, durch welches beim Start des Verbrennungsmotors immer die gleiche Ausgangsituation am Riementrieb vorliegt.The invention has for its object to provide a method for starting an internal combustion engine by means of a belt drive through which there is always the same starting situation on the belt drive at the start of the engine.
Erfindungsgemäß ist die Aufgabe dadurch gelöst, dass auf den Riementrieb bei Stillstand des Verbrennungsmotors ein vorgegebenes Drehmoment zeitlich definiert aufgebracht wird, das kleiner ist als ein zum Starten des Verbrennungsmotors erforderliches Drehmoment. Mittels dieses vorgegebenen Drehmomentes wird die Startposition aller Elemente des Riementriebes optimiert, wobei Freiwinkel überwunden und die Position der verschiedenen Komponenten reproduzierbar eingestellt wird. Bei einem gewünschten Start des Verbrennungsmotors wird die Startzeit verkürzt. Der Verbrennungsmotor kann somit unverzüglich gestartet werden. Akustische Auffälligkeiten bis hin zu unerwünschten, vom Fahrer wahrzunehmenden Vibrationen werden mit einem durch dieses Verfahren voreingestellten Riementrieb verringert. Außerdem erfolgt eine geringere Belastung der Komponenten im Riementrieb beim Start des Riemenstartergenerators.According to the invention the object is achieved in that a predetermined torque is applied in a defined manner to the belt drive at standstill of the internal combustion engine, which is smaller than a torque required for starting the internal combustion engine. By means of this predetermined torque, the starting position of all elements of the belt drive is optimized, wherein clearance angle overcome and the position of the various components is set reproducible. At a desired start of the engine, the start time is shortened. The internal combustion engine can thus be started immediately. Acoustic abnormalities, including unwanted vibrations perceived by the driver, are reduced with a belt drive preset by this method. In addition, there is less stress on the components in the belt drive when starting the belt starter generator.
Vorteilhafterweise wird das vorgegebene Drehmoment nach einem Abschalten des Verbrennungsmotors auf den Riementrieb aufgebracht. Durch die Wahl dieses Zeitpunktes befindet sich der Riementrieb immer in einem zuverlässigen reproduzierbaren Zustand, Die Zeit zum Neustart des Verbrennungsmotors kann beliebig gewählt werden.Advantageously, the predetermined torque is applied to the belt drive after switching off the internal combustion engine. By choosing this time, the belt drive is always in a reliable reproducible state, the time to restart the engine can be chosen arbitrarily.
In einer Ausgestaltung wird das vorgegebene Drehmoment <20 Nm eingestellt. Damit wird sichergestellt, dass sich nur der Riementrieb bewegt. Dieses auf die Kurbelwelle übertragene Moment <20 Nm reicht nicht aus, um den Verbrennungsmotor zu starten.In one embodiment, the predetermined torque <20 Nm is set. This ensures that only the belt drive moves. This moment transmitted to the crankshaft <20 Nm is not enough to start the engine.
In einer Variante wird das vorgegebene Drehmoment am Riementrieb für einen vorgegebenen Zeitraum eingestellt. Dieser Zeitraum soll sehr kurz gewählt werden, um den Energieverbrauch so gering wie möglich zu halten und die Kurbelwelle nicht oder kaum in Bewegung zu bringen.In a variant, the predetermined torque is set on the belt drive for a predetermined period. This period should be chosen very short in order to keep the energy consumption as low as possible and not or hardly bring the crankshaft in motion.
In einer Ausführungsform beträgt der vorgegebene Zeitraum weniger als 0,5 Sekunden. Ein solcher kurzer Zeitraum genügt, um den Riementrieb in die definierte Position und somit einen optimalen Startzustand zu bringen.In one embodiment, the predetermined period is less than 0.5 seconds. Such a short period is enough to bring the belt drive in the defined position and thus an optimal starting state.
In einer Weiterbildung wird der Riementrieb mit einem Riemenstartergenerator und/oder einem Ritzelstarter aktiviert. Das vorgeschlagene Verfahren lässt sich somit auf Riementriebe mit den verschiedensten Antriebskomponenten anwenden.In a further development, the belt drive is activated with a belt starter generator and / or a pinion starter. The proposed method can thus be applied to belt drives with a wide variety of drive components.
Die Erfindung lässt zahlreiche Ausführungsformen zu. Eine davon soll anhand der in der Zeichnung dargestellten Figuren näher erläutert werden.The invention allows numerous embodiments. One of them will be explained in more detail with reference to the figures shown in the drawing.
