Description
Die Erfindung betrifft ein Verfahren zur Regelung eines Antriebsstrangs, für ein Kraftfahrzeug, mit einem Antriebsmotor. Der Antriebsstrang kann einen Verbrennungsmotor und/oder einen elektrischen Motor umfassen. Beide Antriebsstranglösungen können beispielsweise in Bussen oder Kraftfahrzeugen eingesetzt werden. Die vorliegende Erfindung bezieht sich auf die Beschleunigungsregelung dieser Antriebsstränge.The invention relates to a method for controlling a drive train, for a motor vehicle, with a drive motor. The powertrain may include an internal combustion engine and / or an electric motor. Both powertrain solutions can be used for example in buses or motor vehicles. The present invention relates to the acceleration control of these drive trains.
Ein derartiger Antriebsstrang umfasst beispielsweise ein erstes Steuergerät, ein zweites Steuergerät, ein Fahrerwunscheingabemittel, eine Geschwindigkeitserfassungseinrichtung und eine Drehzahlerfassungseinheit zwischen Antriebsmotor und Antriebsrad.Such a drive train comprises, for example, a first control unit, a second control unit, a driver request input means, a speed detection unit and a speed detection unit between the drive motor and the drive wheel.
Weiterhin sind das erste Steuergerät und das zweite Steuergerät über einen CAN-Bus miteinander gekoppelt, so dass Eingangs- und/oder Ausgangssignale zwischen den Steuergeräten (
Es ist beispielsweise bekannter den Antriebsstrang eines Kraftfahrzeugs mittels mehrerer Steuergeräte zu regeln. Im Wesentlichen sind das bei einem Antriebsstrang für z.B. einen Bus mit Verbrennungsmotor das Motorsteuergerät (ECU-Motor) und das Getriebesteuergerät (ECU-Getriebe).It is known, for example, to control the drive train of a motor vehicle by means of a plurality of control devices. Essentially, these are in a powertrain for e.g. a bus with internal combustion engine, the engine control unit (ECU engine) and the transmission control unit (ECU transmission).
So ist weiterhin bekannt, dass das Steuergerät für das Automatikgetriebe direkt mit dem Motor- und/oder Fahrzeugsteuergerät über den CAN-Bus mittels CAN-Nachrichten gemäß den CAN-Protokollen SAE J1939, IES-CAN und/oder VMM-CAN interagiert.Thus, it is also known that the control unit for the automatic transmission directly interacts with the engine and / or vehicle control unit via the CAN bus by means of CAN messages according to the CAN protocols SAE J1939, IES-CAN and / or VMM-CAN.
Die Steuerung des Motors ist derart ausgelegt, dass der Fahrer über die Betätigung des Gaspedals direkten Einfluss auf das Drehmoment des Motors hat. Die Getriebesteuerung ist zwar über den CAN mit der Motorsteuerung gekoppelt, es werden aber nur Signale oder Protokolle auf das Getriebesteuergerät übertragen, die für die Schaltung des Getriebes relevant sind.The control of the engine is designed so that the driver has a direct influence on the torque of the engine via the operation of the accelerator pedal. Although the transmission control is coupled to the engine control via the CAN, only signals or protocols relevant to the transmission's transmission are transmitted to the transmission control unit.
Je nach Beladungszustand des Kraftfahrzeuges, insbesondere Bus, ändert sich aber die mögliche Beschleunigung des Kraftfahrzeugs, da der Motor im geringer belasteten Zustand schneller auf die, über die Motorsteuerung geregelte, Kraftstoffeinspritzung reagiert und schneller ein höheres Drehmoment aufbaut. In Fällen, in denen das verfügbare Motordrehmoment höher ist als das für einen normalen Betrieb erforderliche Niveau, kommt es allerdings zu einem unnötigen zusätzlichen Kraftstoffverbrauch und damit zu höheren Emissionen. Weiterhin kommt es zu einem höheren Verschleiß aller beteiligten Komponenten.Depending on the load condition of the motor vehicle, especially bus, but changes the potential acceleration of the motor vehicle, since the engine reacts faster in the less loaded state on the, controlled by the engine control, fuel injection and faster builds up a higher torque. In cases where the available engine torque is higher than the level required for normal operation, however, there is an unnecessary additional fuel consumption and thus higher emissions. Furthermore, there is a higher wear of all components involved.
Alternativ kann der Antriebsstrang auch einen Elektromotor umfassen, wobei dieser sich ähnlich verhält.Alternatively, the powertrain may also include an electric motor, which behaves similarly.
Um diese unerwünschten Folgen zu vermeiden, werden Begrenzungsparameter für das Fahrzeug mit zulässigem Gesamtgewicht definieren, die auf dem Zustand des voll beladenen Fahrzeugs und den Parametern des Motordatensatzes basieren.In order to avoid these undesirable consequences, maximum permissible vehicle limit parameters will be defined based on the state of the fully laden vehicle and the parameters of the engine data set.
Kraftfahrzeuge, insbesondere Busse, sind im Alltag aber oft nur teilbeladen oder sogar leer im Einsatz.Motor vehicles, especially buses, are in everyday life but often only partially loaded or even empty in use.
Es ist festzustellen, dass, insbesondere bei einem teilbeladenen Fahrzeug, der Fahrereinfluss auf das Fahrzeug zu unerwünschten Fahrzuständen, wie insbesondere einer zu hohen Beschleunigung, führt.It should be noted that, especially in a partially loaded vehicle, the driver's influence on the vehicle leads to undesirable driving conditions, such as, in particular, excessive acceleration.
Deshalb besteht ein Zweck der vorliegenden Erfindung darin, die Regelung eines Antriebstrangs für ein Kraftfahrzeug derart zu verbessern, dass die Effizienz des Kraftfahrzeugs unabhängig vom Fahrer verbessert wird.Therefore, an object of the present invention is to improve the control of a powertrain for a motor vehicle such that the efficiency of the motor vehicle is improved independently of the driver.
Erfindungsgemäß wird diese Aufgabe mit einem Verfahren gemäß Anspruch 1 oder 2 gelöst. Weitere vorteilhafte Ausgestaltungen und bevorzugte Lösungsvarianten sind in den hiervon abhängigen Unteransprüchen beschrieben.According to the invention, this object is achieved by a method according to claim 1 or 2. Further advantageous embodiments and preferred variants of the solution are described in the subclaims dependent thereon.
Der Erfindung liegt die Erkenntnis zugrunde, dass die Effizienz eines Kraftfahrzeuges verbessert werden kann, wenn die maximal mögliche Beschleunigung des Kraftfahrzeugs, unabhängig von Einflussfaktoren wie Fahrzeugführer, Gewicht, Motordrehmoment, Straßentopographie, Reifengröße, Getriebeübersetzung und Differential, begrenzt wird.The invention is based on the finding that the efficiency of a motor vehicle can be improved if the maximum possible acceleration of the motor vehicle is limited, independently of influencing factors such as driver, weight, engine torque, road topography, tire size, gear ratio and differential.
Dazu wird ein Verfahren zur Regelung eines Antriebsstrangs für ein Kraftfahrzeug vorgeschlagen, bei dem im Wesentlichen folgende Schritte ablaufen:
- - ermitteln eines Drehmomentvorgabewertes für die Drehmomentregelung des Kraftfahrzeugantriebsmotors auf Basis mindestens eines Eingangssignals, welches vom Fahrzeugführer gesteuert wird;
- - messen der aktuellen Geschwindigkeit;
- - ermitteln der aktuellen Fahrzeugbeschleunigung;
- - vergleichen der aktuellen Fahrzeugbeschleunigung mit einer vorgebbaren Grenzbeschleunigung für die aktuelle Geschwindigkeit;
- - Ermittlung eines Korrektursignals auf Basis des Vergleiches;
- - anpassen des Drehmomentvorgabewertes auf Basis des Korrektursignals.
- - Determining a torque command value for the torque control of the motor vehicle drive motor based on at least one input signal, which is controlled by the driver;
- - measure the current speed;
- - determine the current vehicle acceleration;
- - Compare the current vehicle acceleration with a predeterminable limit acceleration for the current speed;
- - Determination of a correction signal based on the comparison;
- - Adjust the torque command value based on the correction signal.
In einer Ausführung des Verfahrens umfasst der Antriebsstrang ein Antriebsmotor, ein erstes Steuergerät, ein zweites Steuergerät, ein Fahrerwunscheingabemittel, eine Geschwindigkeitserfassungseinrichtung und eine Drehzahlerfassungseinheit zwischen Antriebsmotor und einem Antriebsrad. Dabei sind das erste Steuergerät und das zweite Steuergerät über einen CAN-Bus miteinander gekoppelt, so dass Eingangs- und/oder Ausgangssignale zwischen den Steuergeräten austauschbar sind. Das Verfahren umfasst folgende Schritte:
- Ermittelt einer Fahrzeugbeschleunigung mittels des zweiten Steuergeräts auf Basis einer Drehzahl, die mittels der Drehzahlerfassungseinheit gemessen wird;
- - Vergleichen der ermittelten Fahrzeugbeschleunigung bei einer gemessenen Geschwindigkeit mit einer in dem zweiten Steuergerät hinterlegten vorgegebenen Fahrzeugbeschleunigung bei der gleichen Geschwindigkeit;
- - generierten eines Ausgangsignals im zweiten Steuergerät;
- - Ermitteln eines Drehmomentausgabesignal zur Regelung des Antriebsmotors auf Basis mindestens eines Eingangssignals im ersten Steuergerät;
- - Anpassen des Drehmomentausgabesignal auf Basis des Ausgangsignals, so dass die tatsächliche Fahrzeugbeschleunigung, unabhängig vom Fahrzeugzustand, vom vorgegebenen Beschleunigungsgrenzwert, bezogen auf die aktuelle Fahrzeuggeschwindigkeit, nicht wesentlich abweicht.
- Determining vehicle acceleration by the second controller based on a speed measured by the speed detection unit;
- - comparing the determined vehicle acceleration at a measured speed with a stored in the second control unit predetermined vehicle acceleration at the same speed;
- - Generating an output signal in the second control unit;
- - Determining a torque output signal for controlling the drive motor based on at least one input signal in the first control unit;
- - Adjusting the torque output signal based on the output signal, so that the actual vehicle acceleration, regardless of the vehicle state, from the predetermined acceleration limit, based on the current vehicle speed, does not differ significantly.
Weiterhin kann der Antriebstrang einen Verbrennungsmotor, eine Einspritzpumpe und ein Getriebe umfassen, wobei das Drehmomentausgabesignal und das angepasste Drehmomentausgabesignal Eingangssignale für die Einspritzpumpenregelung sind.Furthermore, the powertrain may include an internal combustion engine, an injection pump and a transmission, wherein the torque output signal and the adjusted torque output signal are input signals for the injection pump control.
Weiterhin kann mittels der Drehzahlerfassungseinheit die Drehzahl an einer Position entlang des Antriebsstrangs zwischen Getriebeausgang und Fahrzeugrad ermittelt werden.Furthermore, by means of the speed detection unit, the rotational speed can be determined at a position along the drive train between the transmission output and the vehicle wheel.
Das erste Steuergerät kann das Motorsteuergerät sein und das zweite Steuergerät das Getriebesteuergerät.The first control unit may be the engine control unit and the second control unit may be the transmission control unit.

Das Ziel der Erfindung ist es, die Effizienz eines Kraftfahrzeugs, das nur teilweise oder sogar unbeladen ist, zu verbessern.The aim of the invention is to improve the efficiency of a motor vehicle that is only partially or even unloaded.
Bekannt ist, dass der Fahrerwunsch, den der Fahrer durch Betätigung des Fahrpedals
Die relevanten Einflussfaktoren für die Fahrzeugbeschleunigung sind:
- technisches Gewicht
- Motordrehmoment
- Straßentopographie / Routeninformationen
- Reifengröße
- Getriebeübersetzung und Differential (Achsübersetzung).
- technical weight
- engine torque
- Road topography / route information
- wheel size
- Gear ratio and differential (axle ratio).
Diese Faktoren ändern sich von Fahrzeug zu Fahrzeug und Kundenwunsch. Somit auch die von der Motorsteuerung vorgegeben Werte für die Beschleunigungsgrenzwerte.These factors change from vehicle to vehicle and customer requirements. Thus also the values specified by the engine control for the acceleration limits.
Die Beschleunigungsgrenzwerte werden auf der Grundlage von Beschleunigungsversuchen ermittelt, die in einem Testfahrzeug, das mit seinem maximalen technischen Gewicht beladen ist, auf einer ebenen Straße durchgeführt werden. Mit einem solchen Test ist es möglich, die Beschleunigungswerte für beliebige Geschwindigkeitsbereiche zu ermitteln und eine Kennlinie
Das Konzept der vorgeschlagenen technischen Lösung besteht darin, dass bei Teilladungen oder Leerfahrten das Beschleunigungsverhalten annähernd auf das Niveau begrenzt wird, als hätte das Fahrzeug sein maximal zugelassenes Gewicht.The concept of the proposed technical solution is that for partial or empty runs, the acceleration performance is limited approximately to the level as if the vehicle had its maximum permitted weight.
Neu ist, dass die Getriebesteuerung
Über den CAN werden nun nicht nur Signale von der Motorsteuerung
Die CAN-Nachricht, die in dieser technischen Lösung verwendet wird, ist der MEngReq 8, der vom Getriebesteuergerät
Die Beschleunigungswerte des Fahrzeugs (m/s2) werden vom Getriebesteuergerät
Mit Hilfe dieser Signale
Die Drehzahlbereiche für die die Beschleunigungswerte festgelegt werden sind je nach Anwendung und Kundenwunsch (Fahrzeughersteller) frei auswählbar. In
Die Beschleunigungsgrenzen werden als Datensatz in das Getriebesteuergerät geladen, so dass in dem Getriebesteuergerät
Aus
In Teillastversuchen wurde mit dem Beschleunigungsmanagement eine Verbrauchsreduzierung in der Größenordnung von 20% gegenüber dem gleichen Fahrzeugtyp ohne diese Funktionalität erreicht.In partial load tests, the acceleration management achieved a reduction in fuel consumption of the order of 20% compared to the same vehicle type without this functionality.
