Abstract

The invention relates to a method for operating a hybrid vehicle with a combustion engine and an electric motor which can be fed from an electric energy accumulator, the electric motor acting in a lower performance range or speed range as the drive unit and the internal combustion engine acting in an adjacent upper performance range or speed range as the drive unit. In order to optimise consumption, switching over from the electric motor to the internal combustion engine is performed as a function of the daily expected distance covered by the hybrid vehicle with a power value and speed value which are lower for a relatively large daily distance than for a relatively short daily distance, specifically in such a way that on the one hand the electric energy accumulator is at least virtually discharged at the end of the daily distance covered and, on the other hand, the discharging is distributed at least virtually over the entire daily distance covered.

Description

Verfahren zum Betrieb eines Hybridfahrzeuges Method for operating a hybrid vehicle

Die Erfindung bezieht sich auf ein Verfahren zum Betrieb eines Hybridfahrzeuges der im Oberbegriff des Patentanspruchs 1 genannten Art.The invention relates to a method for operating a hybrid vehicle of the type mentioned in the preamble of claim 1.

Bei Hybridfahreugen, die wahlweise durch einen aus einem elektrischen Energiespeicher, z. B. einer kkumulatorenbatterie gespeisten Elektromotor oder einem Verbrennungskraftmotor, insbesondere einem Otto-Motor oder Dieselmotor angetrieben werden, ist es zwecks Verbrauchsoptimierung besonders wichtig, daß beide Motoren å jeweils in einem verbrauchsmäßig zumindest vergleichsweise günstigen Leistungsbereich betrieben werden, es sei denn, daß in besonderen Einsatzfällen anderen Gesichtspunkten (z. B.In the case of hybrid vehicles, which can be optionally combined with one of an electric Energy storage, e.g. B. a battery powered electric motor or a Internal combustion engine, in particular an Otto engine or diesel engine it is particularly important to optimize consumption that both engines å each in a power range that is at least comparatively favorable in terms of consumption be operated, unless in special cases other considerations (e.g.

Emission) Vorrang eingeräumt werden muß.Emission) must be given priority.

Der Kraftstoffverbrauch von Verbrennungskraftmotoren, insbesondere von Otto-Motoren ist bekantltlich im unteren Teillastbereich besonders hoch und im oberen Teillastbereich - nahe Vollast - vergleichsweise günstig. Bei einem flybridfahrzeug ist es daher von Vorteil, wenn im unteren T,eistungs- oder Geschwindigkeitsbereich des Rybridfahrzeuges nicht der in diesem Bereich nur mit einem vergleichsweise schlechten Wirkungsgrad arbeitende Verbrennungskraftmotor, sondern die Elektromaschine als Antriebsmotor eingesetzt wird, die einen vergleichsweise guten Wirkungsgrad aufweist, insbesondere dann, wenn sie eine im Vergleich zum Verbrennungskraftmotor kleine Nennleistung von z. B. nur 10 oder 20 % derselben besitzt.The fuel consumption of internal combustion engines, in particular of Otto engines is known to be particularly high in the lower partial load range and in the upper partial load range - near full load - comparatively cheap. With a flybrid vehicle It is therefore an advantage if in the lower T, power or speed range of the hybrid vehicle not the one in this area only with a comparatively bad one Efficiency working internal combustion engine, but the electric machine as Drive motor is used, which has a comparatively good efficiency, especially if they are small compared to the internal combustion engine Nominal power of z. B. owns only 10 or 20% of the same.

Erfindungsgemäß sind nun die Steuer- und Regelungseinrichtungen eines eine Elektromaschine und einen Verbrennungskraftmotor, insbesondere einen Otto-Motor aufweisenden Hybridfahrzeuges derart ausgebildet, daß die Umschaltung von der Elektromaschine auf den Verbrennungskraftmotor bei einem vorgegebenen Leistungs-oder Geschwindigkeitswert selbsttätig erfolgt und zwar derart, daß der Leistungs- oder Geschwindigkeitswert, bei dem die selbsttätige Umschaltung erfolgt, in Abhängigkeit von der voraussichtlich zurückzulegenden Tagesfahrstrecke des Hybridfahrzeuges verändert wird. Insbesondere wird dieser Leistungs- oder Geschwindigkeitswert derart gewählt, daß die selbsttätige Umschaltung bei einer längeren Tages fahrstrecke bei einem niedrigeren Wert erfolgt als bei einer kürzeren Tagesfahrstrecke und außerdem derart, daß einerseits der elektrische Energiespeicher am Ende der Tagesfahrstrecke zumindest annähernd entladen ist und andererseits die Entladung sich zumindest annähernd über die gesamte Tagesfahrstrecke verteilt.According to the invention, the control and regulation devices are now one an electric machine and an internal combustion engine, in particular an Otto engine having hybrid vehicle designed in such a way that the switchover from the electric machine on the internal combustion engine at a predetermined power or speed value takes place automatically in such a way that the power or speed value, in which the automatic switchover takes place, depending on the expected daily distance to be covered by the hybrid vehicle is changed. In particular this power or speed value is chosen such that the automatic Switching over for a longer daily distance takes place at a lower value than with a shorter daily distance and also such that on the one hand the electrical energy storage at the end of the day's journey at least approximately discharged and on the other hand the discharge is at least approximately over the entire daily distance distributed.

Ausgehend von der Überlegung, daß ein Hybridfahrzeug bei längeren Tagesfahrstrecken häufiger in einem niedrigen Leistungs- bzw. Geschwindigkeitsbereich betrieben werden muß als bei kürzeren Tagesfahrstrecken, wird durch die erfindungsgemäßen Maßnahmen erreicht, daß mit Sicherheit die verbrauchsmäßig besonders ungünstigen Betriebsphasen (niedriger Leistungs- bzw. Geschwindigkeitsbereich) des Verbrennungskraftmotors vermieden werden und zwar während der gesamten Tagesfahrstrecke.Based on the consideration that a hybrid vehicle for longer Daily journeys more often in a low power or speed range must be operated than with shorter daily journeys, is by the invention Measures achieved that with security the particularly unfavorable in terms of consumption Operating phases (low power or speed range) of the internal combustion engine can be avoided during the entire day's journey.

Während bei kürzeren Tagesfahrstrecken ein vergleichsweise großer Teil des ungünstigen unteren teistungsbereiches von der Elektromaschine abgedeckt werden kann, muß man sich wegen der begrenzten Kapazität des elektrischen Energiespeichers bei längeren Tagfahrstrecken damit begnügen, daß nur ein etwas kleinerer Teil, allerdings der verbrauchsmäßig ungünstigste Teil des unteren Leistungs- bvw. Geschwindigkeitsbereiohes des Verbrennungskraftmotors vermieden werden kann; auf die gesamte Tagesfahrstrecke bezogen ergeben sich in beiden Fällen jedoch jeweils die verbrauchs£iäßig optimalen Verhältnisse.While a comparatively large one for shorter daily journeys Part of the unfavorable lower power range of the electric machine covered can be, you have to because of the limited capacity of the electrical energy store in the case of longer day trips, content with the fact that only a slightly smaller part, however the most unfavorable part of the lower power bvw in terms of consumption. Speed range the internal combustion engine can be avoided; on the entire daily distance However, in relation to both cases, the optimum consumption results are obtained Conditions.

Von besonderem Vorteil ist es, wenn die Einstellung des Umschaltwertes mit Hilfe eines auf die Steuerungs- und Regelungsanordnung des Hybridfahrzeuges einwirkenden elektronischen Rechners erfolgt, dem die Daten bezüglich der voraussichtlichen Tagesfahrstrecke dann jeweils vor Fahrtantritt eingegeben werden.It is particularly advantageous if the setting of the switchover value with the help of one on the control and regulation arrangement of the hybrid vehicle acting electronic computer takes place, which the data with respect to the probable The daily distance must then be entered before the start of the journey.

Durch die vorgeschlagenen Maßnahmen wird erreicht, daß die Kapazität des elektrischen Energiespeichers zur Verbrauchsoptimierung des Hybridfahrzeuges wirklich voll ausgenutzt wird. Es wird auf der einen Seite vermieden, daß bei zu niedrigen Werten auf den Verbrennungskraftmotor umgeschaltet wird - die Kapazität des elektrischen Energiespeichers würde nicht voll ausgenutzt werden -, und auf der anderen Seite wird verhindert, daß die Umschaltung auf den Verbrennungskraftmotor bei zu hohen Werten erfolgt, was zur Folge hätte, daß der elektrische Energiespeicher bereits vorzeitig entladen wäre und daher während eines Teiles der Tages fahrstrecke der Verbrennungskraftmotor auch in besonders ungünstigen Leistungs- bzw.The proposed measures ensure that the capacity of the electrical energy storage device to optimize the consumption of the hybrid vehicle is really fully exploited. On the one hand, it is avoided that with to low values are switched to the internal combustion engine - the capacity of the electrical energy storage would not be fully utilized -, and on on the other hand, the switch to the internal combustion engine is prevented takes place at too high values, which would have the consequence that the electrical energy store would be discharged prematurely and therefore during part of the day's journey the internal combustion engine even in particularly unfavorable power or

Geschwindigkeitsbereichen betrieben werden müßte, wodurch der Gesamtwirkungsgrad des Fahrzeuges sinken würde.Speed ranges would have to be operated, reducing the overall efficiency of the vehicle would sink.

Da die tatsächlich zurückgelegte Tagesfahrstrecke häufig nicht voll mit der vorhergesagten Tagesfahrstrecke übereinstimmen wird, kann es mitunter vorkommen, daß der elektrische Energiespeicher entladen ist, ehe die Fahrt zu Ende ist. Dies äre bezüglich des Verbrauches zwar nachteilig, für den allgemeinen Fahrbetrieb jedoch nicht nachteilig. In einem solchen Falle würde der Antrieb des Hybridfahrzuges automatisch auf den Verbrennungskraftmotor umgeschaltet werden, sobald durch die üblicherweise vorhandene Ladezustands-Meßeinrichtung die Entladung des elektrischen Energiespeichers gemeldet werden würde.Since the actual daily distance traveled is often not full will match the predicted daily distance, it can sometimes happen that the electrical energy storage is discharged before the journey is over. this Are disadvantageous in terms of consumption, but for general driving not disadvantageous. In such a case, the hybrid vehicle would be powered automatically can be switched to the internal combustion engine as soon as the usual existing state of charge measuring device the discharge of the electrical energy storage would be reported.
