Abstract

The electric motor car without its power trailer has an autonomous range in the town traffic up to 100km. The electric motors connected to the vehicle's battery propel the motor vehicle's wheels. The battery can be recharged during stops from sockets in the parking places (usually during the night). Analogous to a Diesel-electric engine, the i.c. engine powers the generator and its current, via the battery, drives the motors. In the coupled condition the i.c. engine is controlled by the driver from the passenger space. It can also be operated by an automatic charging regulator to control the recharging of the vehicle's battery and the additional battery which are interchangeable. The power trailer is equipped with a high speed coupling system which allows a quick coupling of the trailer's power when the hybrid vehicle needs to increase its speed over a certain limit and with an automatic trailer steering assembly which facilitates the reverse running. The reserve wheel, the tools and an additional luggage space are also on the power trailer so that the wt. of the electric motor car is minimised and the passenger room maximised. ADVANTAGE - Combines advantages of clear i.c. engine vehicle with advantages of electric drive.

Description

Die Erfindung betrifft ein Hybridfahrzeug mit einem Elektrokraftwagen, der einen Elektroantrieb mit Elektromotor und eine aufladbare Fahrzeugbatterie aufweist; wobei das Hybridfahrzeug weiter mit einem Verbrennungsmotor als Antrieb eines Generators versehen ist, von dem die Fahrzeugbatterie aufgeladen wird.The invention relates to a hybrid vehicle with a Electric car that has an electric drive with an electric motor and has a rechargeable vehicle battery; being the Hybrid vehicle with an internal combustion engine as the drive a generator is provided, of which the vehicle battery is charged.

Bei Hybridantrieben für Kraftfahrzeuge erfolgt der Antrieb üblicherweise durch einen Verbrennungsmotor, der einen Generator antreibt, welcher seinerseits eine Fahrzeugbatterie auflädt. Als Fahrzeugbatterie können beispielsweise herkömmliche Bleiakkumulatoren verwendet werden. An die Fahrzeugbatterie sind Elektromotoren angeschlossen, die die Räder des Kraftfahrzeugs antreiben. Als Elektromotoren für herkömmliche Elektrokraftwagen finden meistens übliche Gleichstromnebenschlußmotoren Verwendung, deren Drehzahl leicht steuerbar ist.The drive takes place in the case of hybrid drives for motor vehicles usually by an internal combustion engine, the one Generator drives, which in turn a vehicle battery charges. As a vehicle battery, for example conventional lead acid batteries are used. To the Vehicle batteries are connected to electric motors, which are the Drive the wheels of the motor vehicle. As electric motors for Conventional electric vehicles are usually used DC shunt motors use, the speed of which is easy is controllable.

Obgleich insbesondere für Omnibusse im Stadtverkehr auch reine Elektrofahrzeuge mit rasch und einfach auswechselbaren Fahrzeugbatterien Anwendung finden, bedeuten die geringe Reichweite, das große Gewicht und Volumen der Akkumulatorbatterien und deren begrenzte Speicherkapazität und damit die begrenzte Reichweite für Personenkraftwagen einen großen Nachteil. Hybridantriebe haben gegenüber herkömmlichen reinen Elektroantrieben den Vorteil, daß die Probleme der begrenzten Reichweite und der langen Wiederaufladezeit der Fahrzeugbatterien überbrückt werden können. Jedoch lassen sich durch einen Hybridantrieb die Volumen- und Gewichtsprobleme nicht beseitigen, sondern nehmen durch den zusätzlichen Verbrennungsmotor eher zu. Zwar können diese Probleme durch eine kleinere Akkumulatorenbatterie reduziert werden, jedoch wäre dann die Reichweite im eigentlich erwünschten reinen Elektrobetrieb ohne laufenden Verbrennungsmotor geringer, was nicht dem Sinn eines Hybridantriebs entspricht.Although especially for buses in city traffic Electric vehicles with quick and easy to replace Vehicle batteries are used mean the low Range, the great weight and volume of the Accumulator batteries and their limited storage capacity and thus the limited range for passenger cars big disadvantage. Hybrid drives have compared to conventional ones pure electric drives have the advantage that the problems of limited range and long recharge time Vehicle batteries can be bridged. However, the volume and weight problems through a hybrid drive do not eliminate, but take through the additional Internal combustion engine rather too. Although these problems can be caused by a smaller accumulator battery can be reduced, however the range would then be in the desired range Electrical operation without a running internal combustion engine less what does not correspond to the sense of a hybrid drive.

Die Erfindung löst die Aufgabe, ein Hybridfahrzeug zu schaffen, welches wahlweise im Kurzstreckenbetrieb ohne die Gewichts- und Bauraumprobleme üblicher Hybridfahrzeuge betreibbar ist.The invention solves the problem of creating a hybrid vehicle which is optionally in short-haul mode without the weight and Space problems of conventional hybrid vehicles can be operated.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Verbrennungsmotor und der Generator auf einem an den bzw. von dem Elektrokraftwagen an- bzw. abkoppelbaren Energieanhänger getragen werden.This object is achieved in that the Internal combustion engine and the generator on one to or from the electric trailer can be connected or disconnected be worn.

Dies hat den Vorteil, daß für den Stadtbetrieb, d. h. für geringe Reichweiten bis maximal 100 km, der Energieanhänger abgekoppelt werden kann. Dieser Energieanhänger kann dann z. B. am Stadtrand auf Park-and-ride-Parkplätzen abgestellt werden. Damit sind für den reinen Stadtbetrieb alle Vorteile eines reinen Elektrokraftwagens realisiert, d. h. die Baugröße und das Gewicht des Fahrzeugs werden durch den Verbrennungsmotor und den Generator nicht zusätzlich belastet. Während der üblichen Stillstandszeiten, die im Stadtverkehr von Personenkraftwagen in der Regel auftreten, kann das Fahrzeug in herkömmlicher Weise über Steckdosen aufgeladen werden. Derartige Stillstandszeiten sind in der Regel nachts, während der Arbeit, oder allgemein beim Parken vorhanden. Unterstützend können Stromanschlüsse am Arbeitsplatz-Parkplatz und an den Parkuhren oder in Parkhäusern vorhanden sein.This has the advantage that for city operations, i.e. H. For short ranges up to a maximum of 100 km, the energy trailer can be uncoupled. This energy trailer can then, for. B. parked on the outskirts in park-and-ride parking lots. This means that all advantages are one for pure city operation purely electric motor vehicle realized, d. H. the size and that Weight of the vehicle is determined by the internal combustion engine and the generator is not additionally loaded. During the usual Downtimes in city traffic of passenger cars Typically, the vehicle can appear in a more conventional manner Way to be charged via sockets. Such Downtime is usually at night, during work, or generally available when parking. Can support Power connections at the workplace parking lot and at the parking meters or in car parks.

Nach Ankoppeln des Energieanhängers lassen sich beliebige Reichweiten realisieren, indem der Verbrennungsmotor den Generator antreibt und dieser die Fahrzeugbatterie während des Fahrens ständig nachlädt. Dabei sind der Verbrennungsmotor und der Generator so bemessen, daß zusätzlich zu der Fahrt mit Höchstgeschwindigkeit die Fahrzeugbatterie ausgehend von ihrem entladenen oder teilentladenen Zustand aufgeladen werden kann.After coupling the energy trailer, any Realize ranges by the internal combustion engine Generator drives and this the vehicle battery during the Driving constantly recharges. The internal combustion engine and the generator dimensioned so that in addition to driving with Top speed the vehicle battery based on your discharged or partially discharged state can be charged.

Ähnlich wie bei dieselelektrischen Lokomotiven ist es jedoch auch möglich, den Strom von dem Generator direkt den Fahrmotoren zuzuführen.However, it is similar to diesel-electric locomotives also possible to direct the current from the generator Feed traction motors.

Im angekoppelten Zustand ist der Verbrennungsmotor vom Fahrer vom Fahrgastraum her bedienbar. D.h. der Motor kann vom Fahrer vom Fahrgastraum her angelassen, die Motorleistung gesteuert und der Verbrennungsmotor wieder abgestellt werden. Bei voll geladener Batterie kann der Motor auch über einen Laderegler automatisch abgestellt werden oder entsprechend bei teilentladener Batterie über den Laderegler automatisch anspringen.When coupled, the combustion engine is from the driver  Can be operated from the passenger compartment. I.e. the engine can by the driver Started from the passenger compartment, engine power controlled and the internal combustion engine can be switched off again. When full The motor can also be charged with a charge controller automatically turned off or at partially discharged battery automatically via the charge controller start an engine.

Nach einer bevorzugten Ausführungsform der Erfindung kann der Energieanhänger mit einem Zusatz-Gepäckraum versehen sein. Vorzugsweise kann der Energieanhänger auch ein Reserverad und Werkzeug tragen. Dadurch wird bei Bedarf, insbesondere bei Langstreckenverkehr, der erforderliche Gepäckraum zur Verfügung gestellt. Auch werden im Kurzstreckenverkehr so gut wie nie genutzte Einrichtungen wie Reserverad und Werkzeug nicht unnötig mittransportiert, da im Falle des Kurzstreckenverkehrs aufgrund der stets relativ geringen Entfernung des Elektrokraftwagens zu dem abgekoppelten Energieanhänger erforderlichenfalls das Reserverad und das Werkzeug aus dem abgekoppelten Energieanhänger besorgt werden können.According to a preferred embodiment of the invention, the Energy trailers with an additional luggage compartment. Preferably, the energy trailer can also be a spare wheel and Carry tools. This will, if necessary, especially when Long haul traffic, the required luggage space available posed. Also in short-haul traffic are almost never not used facilities such as spare wheel and tools unnecessarily transported because in the case of short-haul traffic due to the always relatively short distance of the Electric car to the uncoupled energy trailer if necessary, the spare wheel and the tool from the decoupled energy trailers can be obtained.

Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist der Energieanhänger mit einer automatischen Anhängerlenkung versehen. Dadurch kann das Rückwärtsfahren erleichtert werden. Gemäß einer vorteilhaften Weiterbildung der Erfindung ist der Energieanhänger mit einem Hochgeschwindigkeits-Kopplungssystem zum An- bzw. Abkoppeln an den bzw. von dem Elektrokraftwagen versehen. Durch ein derartiges Kopplungssystem muß die von der derzeitigen Straßenverkehrsordnung vorgesehene Höchstgeschwindigkeit von 80 km/h für den Betrieb mit Anhänger nicht eingehalten werden und das Hybridfahrzeug wird für den zusammengekoppelten Betrieb auch für höhere Geschwindigkeiten zugelassen.According to a further preferred embodiment of the invention is the energy trailer with automatic trailer steering Mistake. This can make reversing easier. According to an advantageous development of the invention Energy trailer with a high-speed coupling system for coupling or uncoupling to or from the electric motor vehicle Mistake. Through such a coupling system, that of the current road traffic regulations Top speed of 80 km / h for operation with a trailer are not adhered to and the hybrid vehicle is used for the coupled operation also for higher speeds authorized.

Nach einer anderen bevorzugten Weiterbildung der Erfindung ist der Verbrennungsmotor mit dem Generator sowohl bei an- als auch bei abgekoppeltem Energieanhänger betreibbar und der Energieanhänger trägt eine Zusatzbatterie, die zum Aufladen derselben mit dem Generator verbunden ist. Die Zusatzbatterie kann damit auch bei abgekoppeltem Energieanhänger aufgeladen werden. Dazu kann der Verbrennungsmotor bei abgekoppeltem Energieanhänger auch von außen angelassen und die Motorleistung eingestellt werden. Ein Laderegler stellt den Verbrennungsmotor dann ab, sobald die Batterie voll geladen ist.According to another preferred development of the invention the internal combustion engine with the generator both on and off can be operated when the energy trailer is disconnected and the Energy trailer carries an auxiliary battery that is used for charging  the same is connected to the generator. The auxiliary battery can be charged even when the energy trailer is disconnected will. For this purpose, the internal combustion engine can be disconnected Energy trailers also left on from the outside and the engine power can be set. A charge controller provides the internal combustion engine then off as soon as the battery is fully charged.

Der Verbrennungsmotor kann schalldicht gekapselt sein, wodurch die Geräuschentwicklung ähnlich einem Notstromaggregat gering gehalten werden kann. Wenn die Fahrzeugbatterie des Elektrokraftwagens annähernd entleert ist, kann durch Ankoppeln des Anhängers dann das gesamte Hybridfahrzeug über die aufgeladene Zusatzbatterie weiter im reinen Elektrobetrieb ohne laufenden Verbrennungsmotor verwendet werden.The internal combustion engine can be encapsulated so that it is soundproof the noise level is similar to that of an emergency generator can be held. If the vehicle battery of the Electric vehicle is almost empty, by coupling of the trailer then the entire hybrid vehicle over the Charged additional battery continues in pure electrical operation without running internal combustion engine can be used.

Insbesondere bei Verwendung einer in dem Energieanhänger angeordneten Zusatzbatterie kann die Kapazität der Fahrzeugbatterie des von dem Anhänger gelösten Elektrokraftwagens mit der Zielsetzung eines geringeren Fahrzeuggewichts unter Inkaufnahme einer geringeren Reichweite des von dem Anhänger gelösten Elektrokraftwagens verringert werden, da sich der reine Elektrobetrieb durch Ankoppeln des Anhängers fortsetzen läßt.Especially when using one in the energy trailer arranged auxiliary battery can the capacity of the Vehicle battery of the detached from the trailer Electric car with the objective of a lower Vehicle weight while accepting a shorter range of the electric vehicle released from the trailer be, since the pure electrical operation by coupling the Trailer can continue.

Nach einer anderen bevorzugten Weiterbildung der Erfindung sind die Fahrzeugbatterie und die Zusatzbatterie gegeneinander austauschbar. So kann die Zusatzbatterie durch den schalldicht gekapselten Verbrennungsmotor unabhängig von dem Elektrokraftwagen aufgeladen werden, und die unter Umständen identisch ausgebildete Fahrzeugbatterie und Zusatzbatterie können gegeneinander ausgetauscht werden, wodurch sich der von dem Anhänger gelöste Elektrokraftwagen einzeln weiter betreiben läßt, während die leere Batterie nun aufgeladen wird.According to another preferred development of the invention the vehicle battery and the auxiliary battery against each other interchangeable. So the additional battery can be soundproofed encapsulated internal combustion engine regardless of the Electric cars can be charged, and possibly Identically designed vehicle battery and auxiliary battery can be exchanged for each other, whereby the of continue to operate the electric vehicle released from the trailer individually leaves while the empty battery is being charged.

Nach einer anderen vorteilhaften Weiterbildung der Erfindung ist der Verbrennungsmotor mit einem ersten Ende einer Kardanwelle verbunden, mittels deren zweitem Ende bei angekoppeltem Energieanhänger das Fahrzeug über eine Kupplung und ein Getriebe direkt antreibbar ist. Gemäß dieser Weiterbildung der Erfindung läßt sich ein Zusammenwirken der Vorteile eines reinen Verbrennungskraftfahrzeugs mit den Vorteilen eines Elektroantriebs in idealer Weise kombinieren, da das Hybridfahrzeug insbesondere im Langstreckenbetrieb als reines Verbrennungskraftfahrzeug betreibbar ist, wobei der Wirkungsgrad aufgrund des Direktantriebs höher als bei Umwandlung in elektrische Energie durch einen Generator ist.According to another advantageous development of the invention is the internal combustion engine with a first end Cardan shaft connected by means of the second end at coupled energy trailer the vehicle via a coupling  and a transmission can be driven directly. According to this Development of the invention can be a cooperation of Advantages of a pure combustion engine with the Combine the advantages of an electric drive in an ideal way, since the hybrid vehicle, especially in long-distance operation pure internal combustion engine is operable, the Efficiency higher than with due to the direct drive Conversion to electrical energy by a generator.
