Description

Die Erfindung betrifft ein Antriebssteuerungssystem und ein Verfahren zum Starten einer Brennkraftmaschine eines fahrenden Hybridfahrzeuges.The The invention relates to a drive control system and method for starting an internal combustion engine of a moving hybrid vehicle.

Bei einem Antriebsstrang für Hybridfahrzeuge, der als Einwellen-Parallelhybrid ausgeführt ist, ist eine Elektromaschine mit der Antriebsachse über ein Getriebe verbunden. Bei einer Ausführung als Vollhybrid ist zusätzlich zwischen der Brennkraftmaschine und der Elektromaschine eine Trennkupplung angeordnet. Je nach Schaltstellung der Trennkupplung kann das Fahrzeug durch die Brennkraftmaschine, die Elektromaschine oder beide Aggregate betrieben werden. Bei Betrieb durch die Brennkraftmaschine kann die Elektromaschine entweder motorisch als Drehmomentquelle oder generatorisch zum Laden der Batterie genutzt werden. Die Elektromaschine kann auch zum Starten der Brennkraftmaschine genutzt werden, wenn ein entsprechendes Signal vorhanden ist, das den Start einer Brennkraftmaschine signalisiert. Von der Elektromaschine wird die benötigte Energie aufgebracht und die Kupplung zur Brennkraftmaschine geschlossen. Mit dem durch die schließende Trennkupplung übertragenen Moment ist der Start der Brennkraftmaschine möglich. Wird der Elektromaschine keine zusätzliche Energie zugeführt, so kommt es zu einem Abfall des für den Antrieb zur Verfügung stehenden Moments, da ein Teil des Momentes zum Andrehen der Brennkraftmaschine benötigt wird. Dieser Abfall kann vom Fahrer gegebenenfalls als Ruck gespürt werden.at a powertrain for hybrid vehicles, the single-shaft parallel hybrid is executed, is an electric machine with the drive axle over connected to a transmission. In one embodiment as a full hybrid is in addition between the internal combustion engine and the Electric machine arranged a separating clutch. Depending on the switch position The disconnect clutch can power the vehicle through the internal combustion engine Electric machine or both units are operated. During operation by the internal combustion engine, the electric machine can either motor used as a torque source or as a generator for charging the battery become. The electric machine can also be used to start the internal combustion engine be used if a corresponding signal is present, the signaled the start of an internal combustion engine. From the electric machine the required energy is applied and the clutch closed to the internal combustion engine. With the closing Disconnect torque transmitted is the start of the engine possible. Will the electric machine no additional Energy is supplied, it comes to a drop in the the moment available to the drive, as part of the Moment is needed to crank the internal combustion engine. This waste may be felt by the driver as a jolt become.

Aus der DE 698 31 468 T2 ist ein gattungsgemäßes Antriebssteuerungssystem zum Starten einer Brennkraftmaschine eines fahrenden Hybridfahrzeuges bekannt, wobei eine Unterstützungsstelleinrichtung ein Drehmoment der Elektromaschine erhöht, um das zusätzliche Drehmoment für das Starten der Brennkraftmaschine zu kompensieren. Hierdurch wird zwar ein Rucken des Fahrzeuges sicher vermieden, jedoch wird entsprechend stark die Batterie für die Elektromaschine belastet.From the DE 698 31 468 T2 For example, a generic drive control system for starting an internal combustion engine of a moving hybrid vehicle is known, wherein an assisting device increases a torque of the electric machine to compensate for the additional torque for starting the internal combustion engine. As a result, while a jerk of the vehicle is safely avoided, however, the battery is charged correspondingly strong for the electric machine.

Der Erfindung liegt das technische Problem zugrunde, ein Antriebssteuerungssystem sowie ein Verfahren zum Starten einer Brennkraftmaschine eines fahrenden Hybridfahrzeuges zu schaffen, mittels derer ohne spürbare Komforteinbußen die elektrische Energieaufnahme der Elektromaschine reduziert werden kann.Of the The invention is based on the technical problem of a drive control system and a method for starting an internal combustion engine of a moving Hybrid vehicle to create, by means of which without noticeable Loss of comfort the electrical energy consumption of the electric machine can be reduced.

Die Lösung des technischen Problems ergibt sich durch die Gegenstände mit den Merkmalen der Patentansprüche 1 und 5. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The Solution of the technical problem results from the objects with the features of claims 1 and 5. Further advantageous embodiments of the invention will become apparent from the Dependent claims.

Hierzu umfasst das Antriebssteuerungssystem zum Starten einer Brennkraftmaschine eines fahrenden Hybridfahrzeuges eine Brennkraftmaschine und eine Elektromaschine, wobei die Brennkraftmaschine mit der Elektromaschine über eine Trennkupplung verbunden ist und die Elektromaschine über ein Getriebe mit der Antriebsachse verbunden ist, eine Startaufforderungsbestimmungseinrichtung, um eine Aufforderung zum Starten der Brennkraftmaschine zu bestimmen, und eine Unterstützungsstelleinrichtung, um das Ausgangsdrehmoment der Elektromaschine zu erhöhen, wenn eine Aufforderung zum Starten der Brennkraftmaschine erfasst wird, wobei das notwendige zusätzliche Antriebsmoment der Elektromaschine zum Starten der Brennkraftmaschine ermittelt oder geschätzt wird, wobei das zusätzliche Antriebsmoment der Elektromaschine in einen elektrischen Anteil und einen kinetischen Anteil aufgespalten wird, wobei der kinetische Anteil über das Getriebe von der Antriebsachse auf die Elektromaschine übertragen wird, wobei der kinetische Anteil in Abhängigkeit von Fahrzeugzustandsdaten bestimmt wird. Die Erfindung geht dabei von der Erkenntnis aus, dass fahrzustandsabhängig ein Teil der kinetischen Energie des Fahrzeugs zum Starten der Brennkraftmaschine verwendet werden kann, ohne dass der Fahrer dies merklich spürt. Somit muss entsprechend weniger elektrische Energie der Elektromaschine zugeführt werden, da diese nur noch ein zusätzliches Restmoment aufbringen muss. Im Extremfall kann der kinetische Anteil bis zu 100% betragen. Der andere Extremfall ist, dass der elektrische Anteil 100% beträgt. Weiter kann vorgesehen sein, dass der Fahrer einstellen kann, ob und wie ausgeprägt der kinetische Anteil zum Starten benutzt wird.For this includes the drive control system for starting an internal combustion engine a moving hybrid vehicle, an internal combustion engine and a Electric machine, wherein the internal combustion engine with the electric machine over a separating clutch is connected and the electric machine via a transmission is connected to the drive axle, a start request determination device to determine a request to start the internal combustion engine and an assisting device to adjust the output torque to increase the electric machine when prompted to Starting the internal combustion engine is detected, with the necessary additional drive torque of the electric machine for starting the internal combustion engine is determined or estimated, wherein the additional drive torque of the electric machine in one electric component and a kinetic component is split, being the kinetic component via the gearbox of the drive axle is transferred to the electric machine, the kinetic Share determined depending on vehicle condition data becomes. The invention is based on the knowledge that driving state dependent a part of the kinetic energy of the vehicle for starting the internal combustion engine can be used without the driver feeling this noticeable. Thus, correspondingly less electrical energy of the electric machine be supplied, since these only an additional Has to spend residual moment. In extreme cases, the kinetic component up to 100%. The other extreme case is that the electrical part 100%. It can also be provided that the driver can adjust whether and how pronounced the kinetic component is used for starting.

Vorzugsweise sind die Fahrzeugzustandsdaten die Geschwindigkeit des Hybridfahrzeuges und der eingelegte Gang. Die Fahrzeuggeschwindigkeit ist dabei ein Maß für die kinetische Energie des Fahrzeugs, wobei der Gang bzw. das Übersetzungsverhältnis die Übertragungseigenschaften bzw. Dämpfungseigenschaften widerspiegelt, also wie stark die Rückwirkung ist. Im Folgenden und den Ansprüchen wird unter dem eingelegten Gang jeweils ein Übersetzungsverhältnis verstanden. Die Begriffe „eingelegter Gang” können somit als Synonym für die Begriffe „gegenwärtiges Übersetzungsverhältnis” angesehen werden. Als Faustregel gilt, dass je höher die Fahrzeuggeschwindigkeit ist, desto mehr kinetische Energie kann zum Starten rückwirkungsfrei verwendet werden. Entsprechend gilt, dass je kleiner der Gang ist, desto weniger kinetische Energie kann rückwirkungsfrei entnommen werden. Die Zuordnung zwischen Gang und Geschwindigkeit zu Anteil bzw. Absolutmaß der kinetischen Energie kann in entsprechenden Kennlinien abgelegt werden, die gegebenenfalls empirisch bestimmt werden.Preferably For example, the vehicle state data is the speed of the hybrid vehicle and the inserted gear. The vehicle speed is here Measure of the kinetic energy of the vehicle, where the gear or the gear ratio the transmission properties or damping properties reflects how strong the feedback is. Hereinafter and the claims will be under the gear each understood a translation ratio. The terms "inlaid Gang "can thus be synonymous with the Terms "current gear ratio" become. As a rule of thumb, the higher the vehicle speed is, the more kinetic energy can be re-free to start be used. Similarly, the smaller the gait, The less kinetic energy can be reactive be removed. The association between gear and speed to proportion or absolute measure of kinetic energy can be stored in appropriate characteristics, if necessary determined empirically.

In einer weiteren bevorzugten Ausführungsform wird bei der Ermittlung oder Schätzung des zusätzlichen Antriebsmoments die Temperatur der Brennkraftmaschine und/oder die Stellung der Kolben berücksichtigt. Dadurch kann das Antriebsmoment noch genauer bestimmt werden.In a further preferred embodiment form the temperature of the internal combustion engine and / or the position of the piston is taken into account in the determination or estimation of the additional drive torque. As a result, the drive torque can be determined even more accurately.

In einer weiteren bevorzugten Ausführungsform ist das Getriebe als Automatikgetriebe oder als Doppelkupplungsgetriebe ausgebildet, wobei zur Übertragung des kinetischen Teils auf die Elektromaschine eine Wandlerüberbrückungskupplung des Automatikgetriebes angesteuert wird.In Another preferred embodiment is the transmission designed as an automatic transmission or as a double-clutch transmission, wherein for transmitting the kinetic part to the electric machine a lockup clutch of the automatic transmission is controlled.

Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispieles näher erläutert. Die einzige Figur zeigt ein schematisches Blockschaltbild eines Antriebssteuerungssystems.The Invention will be described below with reference to a preferred embodiment explained in more detail. The single figure shows a schematic Block diagram of a drive control system.

Das Antriebssteuerungssystem 1 zum Starten einer Brennkraftmaschine 2 eines fahrenden Hybridfahrzeuges umfasst eine Brennkraftmaschine 2, eine Elektromaschine 3, ein Getriebe 4, eine Trennkupplung 5, eine Leistungselektronik 6, eine Traktionsbatterie 7, ein Motorsteuergerät 8, ein Steuergerät 9 der Elektromaschine 3 und ein Getriebesteuergerät 10, wobei die Steuergeräte 8–10 über einen Bus 11 miteinander verbunden sind. Des Weiteren umfasst das Antriebssteuerungssystem 1 eine nicht dargestellte Startanforderungsbestimmungseinrichtung und eine Unterstützungsstelleinrichtung. Die Unterstützungsstelleinrichtung ist vorzugsweise in dem Steuergerät 9 integriert, wobei die Startanforderungsbestimmungseinrichtung in dem Motorsteuergerät, dem Steuergerät 9 oder einem nicht dargestellten übergeordneten Hybrid-Steuergerät (wenn vorhanden) oder einem Energie-Management-Steuergerät (wenn vorhanden) integriert sein kann.The drive control system 1 for starting an internal combustion engine 2 a moving hybrid vehicle includes an internal combustion engine 2 , an electric machine 3 , a gearbox 4 , a separating clutch 5 , a power electronics 6 , a traction battery 7 , an engine control unit 8th , a control unit 9 the electric machine 3 and a transmission control unit 10 , where the controllers 8th - 10 over a bus 11 connected to each other. Furthermore, the drive control system includes 1 an unrepresented start request determining means and a support setting means. The assisting device is preferably in the control unit 9 integrated, wherein the start request determination means in the engine control unit, the control unit 9 or an unillustrated parent hybrid controller (if present) or an energy management controller (if any) may be integrated.

Im Ausgangszustand ist die Trennkupplung 5 offen und die Brennkraftmaschine 2 abgeschaltet. Das gesamte Antriebsmoment des Hybridfahrzeuges wird durch die motorisch betriebene Elektromaschine 3 aufgebracht. Erfasst nun die Startaufforderungsbestimmungseinrichtung, dass aus energetischen Gründen eine Zuschaltung der Brennkraftmaschine 2 sinnvoll ist, so erzeugt diese ein entsprechendes Signal. Die Unterstützungsstelleinrichtung ermittelt dann zunächst, was für ein zusätzliches Antriebsmoment zum Andrehen der Brennkraftmaschine 2 benötigt wird. Dieses Moment kann beispielsweise vorab empirisch ermittelt werden und als Wert abgelegt werden. Dabei ist es denkbar, diesen Wert in Abhängigkeit weiterer Parameter wie Temperatur der Brennkraftmaschine 2 und/oder Stellung der Kolben zu parametrieren. Weiter erhält die Unterstützungsstelleinrichtung die Geschwindigkeit des Fahrzeugs (vorzugsweise vom Motorsteuergerät 8) sowie den eingelegten Gang vom Getriebesteuergerät 10. Anhand der Fahrzeuggeschwindigkeit und des eingelegten Ganges wählt die Unterstützungsstelleinrichtung aus, wie viel des zusätzlichen Antriebsmoments für die Brennkraftmaschine 2 durch die kinetische Energie des Fahrzeugs geliefert werden soll, wobei dies möglichst rückwirkungsfrei auf den Antrieb erfolgen soll. Dabei gilt, dass mit zunehmender Geschwindigkeit der Anteil an kinetischer Energie steigen kann. Gleiches gilt für höhere Gangstufen. Dabei kann die Zuordnung Geschwindigkeit/Gang – kinetischer Anteil in Kennfeldern abgelegt sein. Entsprechend steuert die Unterstützungsstelleinrichtung die Leistungselektronik 6, so dass der verbleibende elektrische Anteil durch die Traktionsbatterie 7 geliefert wird. Des Weiteren wird das Getriebesteuergerät 10 informiert, das Getriebe 4 derart anzusteuern, dass eine Drehmomentübertragung von den Rädern über die Antriebsachse auf die Elektromaschine 3 ermöglicht wird. Hierzu wird beispielsweise bei einem Automatikgetriebe die Überbrückungskupplung geschlossen.In the initial state is the separating clutch 5 open and the internal combustion engine 2 off. The entire drive torque of the hybrid vehicle is through the motor-driven electric machine 3 applied. Now detects the start request determination device that, for energetic reasons, a connection of the internal combustion engine 2 makes sense, this generates a corresponding signal. The support adjusting device then first determines what kind of additional drive torque for cranking the internal combustion engine 2 is needed. This moment, for example, can be determined empirically in advance and stored as a value. It is conceivable, this value depending on other parameters such as temperature of the internal combustion engine 2 and / or setting the position of the pistons. Further, the assisting setting device receives the speed of the vehicle (preferably from the engine control unit 8th ) and the gear engaged by the transmission control unit 10 , Based on the vehicle speed and the engaged gear selects the support adjustment means, how much of the additional drive torque for the internal combustion engine 2 should be supplied by the kinetic energy of the vehicle, this should be possible without interference on the drive. It is true that with increasing speed, the proportion of kinetic energy can increase. The same applies to higher gear ratios. The assignment speed / speed - kinetic proportion can be stored in maps. Accordingly, the assisting device controls the power electronics 6 so that the remaining electrical part through the traction battery 7 is delivered. Furthermore, the transmission control unit 10 informed, the transmission 4 to control such that a torque transmission from the wheels via the drive axle to the electric machine 3 is possible. For this purpose, for example, in an automatic transmission, the lock-up clutch is closed.
