Abstract

The control system regulates the energy flow in a hybrid electric car. The internal combustion engine (1) is regulated by a speed controller to run at constant speed independently of its load. Consequently its control system is decoupled from the remaining components of the drive system. The internal combustion engine (1) drives a synchronous generator (2). The 3-phase AC produced is fed to a rectifier (3) via a switch (6). A capacitor and an accumulator battery (5) are connected across the output from the rectifier. The rectifier and battery DC output are connected to an inverter (4) which supplies variable frequency 3-phase AC to a motor-generator (M/G) driving the front or rear wheels of the car. The accelerator pedal is connected to the inverter to control the frequency. The brake pedal may also be connected to the inverter to control regenerative braking.

Description

Im einfachsten Fall sind das:
In the simplest case, these are:

  • - Ein elektrischer Energiespeicher. Dafür kommen sowohl Batterien die bei Raumtemperatur als auch bei erhöhter Temperatur arbeiten als auch- An electrical energy storage. Both batteries come with it Room temperature as well as working at elevated temperature as well
  • - Brennstoffzellen oder- fuel cells or
  • - Kreiselspeicher- Gyro memory

in Frage.in question.

Der Antrieb des Fahrzeuges kann so erfolgen, daß nur eine Energiequelle oder aber auch mehrere (im einfachsten Fall zwei Energiequellen) zur Energiebereitstellung genommen werden. Grundsätzlich kann das Zusammenwirken der Energiespeicher, wie in Abb. 1 dargestellt erfolgen. In dem einen Fall ist noch ein mechanischer Antriebsstrang vorhanden. Im zweiten Fall ist dieser nicht vorhanden. Letztere Anordnung soll weiter betrachtet werden.The vehicle can be driven in such a way that only one energy source or else several (in the simplest case two energy sources) are used for the provision of energy. Basically, the interaction of the energy stores can take place, as shown in Fig. 1. In the one case there is still a mechanical drive train. In the second case this is not available. The latter arrangement will be considered further.

Der Fahrbetrieb kann so erfolgen, daß
Driving can be done so that

  • 1. Der Verbrennungsmotor (1) treibt den Synchrongenerator (2) mit konstanter Drehzahl an. Dessen Energieentnahme erfolgt über einen Gleichrichter (3) der einen Inverter (4) speist. Dieser speist momentengeregelt den Drehstromfahrmotor, der die Räder des Fahrzeuges antreibt.1. The internal combustion engine ( 1 ) drives the synchronous generator ( 2 ) at a constant speed. Its energy is extracted via a rectifier ( 3 ) which feeds an inverter ( 4 ). This feeds the three-phase traction motor, which drives the wheels of the vehicle, in a torque-controlled manner.
  • 2. Der elektrische Energiespeicher (5) liefert Energie an den Inverter (4) der in der o.a. Weise den Fahrmotor speist.2. The electrical energy store ( 5 ) supplies energy to the inverter ( 4 ) which feeds the drive motor in the above manner.
  • 3. Die Antriebsenergie wird gleichzeitig von beiden Energiequellen geliefert, 3. The drive energy is supplied simultaneously by both energy sources,  
  • 4. Die Energie des vom Verbrennungsmotor getriebenen Generators (2) wird zur Aufladung des Energiespeichers verwendet. Dabei wird der Gleichrichter (3) zur Regelung des Ladestromes verwendet. Diese Betriebsart kann bei stillstehendem Fahrzeug ebenso wie bei Fahrbetrieb auftreten. Im letzteren Fall dann, wenn die Energie des Verbrennungsmotors nicht vollständig für den Fahrbetrieb benötigt wird.4. The energy of the generator ( 2 ) driven by the internal combustion engine is used to charge the energy store. The rectifier ( 3 ) is used to regulate the charging current. This operating mode can occur when the vehicle is stationary as well as when driving. In the latter case, when the energy of the internal combustion engine is not completely required for driving.

Während bei den Betriebsweisen 1 und 2 eindeutig die Energiezufuhr und deren Regelung sich aus der o.a. Beschreibung ergibt, ist bei den unter 3 und 4 beschriebenen Betriebsweisen der Energiefluß so zu regeln, daß beide Energiequellen an der Energiebereitstellung teilnehmen können. Dafür werden Fahrzeugsteuerungen verwendet, die wie in Abb. 1 dargestellt, der Fahrzeugelektronik übergeordnet sind. Sie einzusetzen erfordert die genaue Kenntnis der Kennlinien des Verbrennungsmotors ebenso wie die Kennlinien des Lade- und Entladeregimes des Energiespeichers. Es werden elektronische Aufwendungen für die Hard- und Software erforderlich. Dieser Nachteil soll durch die folgende Lösung vermieden werden.While in modes of operation 1 and 2 the energy supply and their regulation clearly result from the above description, in the modes of operation described in 3 and 4 the energy flow is to be regulated so that both energy sources can participate in the provision of energy. For this purpose, vehicle controls are used which, as shown in Fig. 1, are superior to the vehicle electronics. Using them requires precise knowledge of the characteristics of the internal combustion engine as well as the characteristics of the charging and discharging regime of the energy storage device. Electronic expenses for the hardware and software are required. This disadvantage is to be avoided by the following solution.

Es erfolgt eine regelungstechnische Entkopplung der Drehzahlregelung des Verbrennungsmotors von den übrigen Aufgaben. Hierzu wird ein an sich bekannter Drehzahlregler, wie er bei Verbrennungsmotoren üblich ist, in der Form eingesetzt, daß der die Motordrehzahl auf einen Festwert einregelt, die unter dem Aspekt der Abgasverunreinigung optimal ist.There is a decoupling of the speed control of the Internal combustion engine from the other tasks. For this, a known per se Speed controller, as is common in internal combustion engines, used in the form that which regulates the engine speed to a fixed value, which from the aspect of Exhaust gas pollution is optimal.

Die Leistungsentnahme des von Verbrennungsmotor angetriebenen Generators wird durch einen regelbaren Gleichrichter auf den maximal zulässigen Wert, der der Nennleistung des Verbrennungsmotors entspricht, begrenzt. Dieser Gleichrichter arbeitet also als Strombegrenzer. Damit ist gewährleistet, daß bei allen vorkommenden Betriebsarten, der Verbrennungsmotor nicht überlastet wird und sich die gleichgerichtete Spannung dem Ladezustand der Batterie beim Ladebetrieb im Fahrzeugstillstand wie bei Fahrbetrieb anpaßt. Dafür werden keine Kenntnisse der Batteriekennlinien oder der Motorkennlinien benötigt. Soll reiner Ladebetrieb bei Fahrzeugstillstand gefahren werden, so kann mittels einer Sollwertvorgabe der gewünschte Ladestrom eingestellt werden. Sein Wert kann jedoch den der Strombegrenzung nicht überschreiten. The power consumption of the generator driven by the internal combustion engine is by an adjustable rectifier to the maximum permissible value that the Nominal output of the internal combustion engine corresponds, limited. This rectifier works so as a current limiter. This ensures that all occurring Operating modes, the internal combustion engine is not overloaded and the rectified Voltage the state of charge of the battery when charging with the vehicle at a standstill as for Adapts driving operation. For this no knowledge of the battery characteristics or the Motor characteristics required. Should only be used when the vehicle is stationary the desired charging current can be set by means of a setpoint become. However, its value cannot exceed that of the current limit.  

Die Momentenregelung des Fahrmotors erfolgt durch den Inverter. Dieser erhält vom Beschleunigerpedal, das mit einem analogen oder digitalen Geber mechanisch verbunden ist, den Momentensollwert vorgegeben.The torque control of the traction motor is carried out by the inverter. This receives from Accelerator pedal that is mechanically connected to an analog or digital encoder is specified, the torque setpoint.

Auf diese Art und Weise ist auch Bremsbetrieb möglich. Hierzu sind die folgenden Lösungen vorzusehen:
Braking is also possible in this way. The following solutions must be provided for this:

  • 1. Das Beschleunigerpedal erhält im Bereich zwischen den beiden Endstellungen eine Raststellung, die dem Moment "Null" entspricht. Wird diese in Richtung obere Endlage überschritten, so erhält der Inverter einen Sollwert für ein Bremsmoment was abhängig von der Pedalstellung ist.1. The accelerator pedal receives one in the area between the two end positions Rest position that corresponds to the moment "zero". If this is towards the top Limit position exceeded, the inverter receives a setpoint for a braking torque depends on the pedal position.
  • 2. Mit dem Bremspedal ist ein analoger oder digitaler Geber verbunden. Dieser bewirkt daß im Anfangsbereich des Bremspedalweges der Inverter einen Sollwert für ein Bremsmoment erhält.2. An analog or digital encoder is connected to the brake pedal. This causes that in the initial area of the brake pedal travel the inverter a setpoint for a Receives braking torque.

In beiden Fällen fließt Energie vom Fahrmotor in den Zwischenkreis und von dort in die Batterie. Die Rückgewinnung von Bremsenergie ist nur bei zugeschalteter Batterie möglich.In both cases, energy flows from the traction motor into the intermediate circuit and from there into the Battery. The recovery of braking energy is only possible when the battery is switched on possible.

Der Inverter besitzt eine Strombegrenzung, so daß der Fahrmotor nicht überlastet wird. Der parallele Betrieb des Fahrzeuges aus zwei Energiequellen erfolgt derartig, daß bei zugeschalteter Batterie zunächst nur eine Energieentnahme aus dem Synchrongenerator erfolgt. Das bedeutet, daß der Synchrongenerator sowohl Energie an den Inverter. Für den Fahrbetrieb liefert, als auch Energie an die Batterie abgibt. Übersteigt der Energiebedarf den Nennwert, so regelt der Gleichrichter an der Strombegrenzung die in den Zwischenkreis gelieferte Spannung herab. Damit wird es möglich, daß die Batterie Energie abgeben kann. Das tritt immer dann auf, wenn an Steigungen, bei Beschleunigung oder bei hoher Geschwindigkeit der Energiebedarf des Antriebsmotors größer als die vom Verbrennungsmotor bereitgestellte Energie ist.The inverter has a current limit so that the drive motor is not overloaded. The parallel operation of the vehicle from two energy sources is such that at connected battery initially only an energy withdrawal from the synchronous generator he follows. This means that the synchronous generator supplies both energy to the inverter. For provides driving operations, as well as delivering energy to the battery. If the Energy demand the nominal value, the rectifier regulates the current limit in voltage supplied to the intermediate circuit. This makes it possible for the battery Can give off energy. This always occurs when on inclines Acceleration or at high speed the energy requirement of the drive motor is greater than the energy provided by the internal combustion engine.

Soll die Fahrenergie nur durch die Batterie bereitgestellt werden, so wird mittels des Schalters (6) der Synchrongenerator vom Gleichrichter getrennt. Da das im stromlosen Zustand möglich ist kann ein Trennschalter verwendet werden.If the driving energy is only to be provided by the battery, the switch ( 6 ) is used to separate the synchronous generator from the rectifier. Since this is possible when the power is off, a disconnector can be used.

Mit dieser Lösung wird erreicht, daß ein Gerät für die Fahrzeugsteuerung nicht erforderlich ist.This solution ensures that a device for vehicle control is not is required.
