Definitions

  • This invention relates to motor vehicle power plants, and more particularly, to "hybrid" motor vehicles powered by both electrical and fossil fuel power plants. Still more particularly, the present invention relates to a parallel hybrid electric/fossil fuel power plant for a motor vehicle such as a passenger car, in which the electric motor shaft is connected in parallel with an internal combustion engine shaft, and the electric motor is controlled to balance the load of the internal combustion engine.
  • the batteries also have to be recharged somehow once they become “dead.”
  • an alternator converts power from the internal combustion engine into electricity for recharging the battery. If there were no internal combustion engine, the recharging power would have to come from some other source. While some recharging power could come from the force of gravity (for example, the momentum from going down a hill could be converted into electricity), most of the recharging power would have to come from somewhere else — such as an electric wall socket the car owner plugs his car into every night.
  • This battery recharging process could take many hours or even overnight — as compared with the essentially instant refilling of a passenger car gas tank at a filling station.
  • the idea that electric power is clean and non-polluting is a fiction. Although some electric power plants (for example, nuclear and hydroelectric power plants) do not pollute the air, the vast majority of electric power plants in the United States burn coal or other combustible materials — and therefore are major polluters. Some people say that an all-electric vehicle would simply move air pollution from individual car exhausts to electric power plant smokestacks.
  • hybrid electric vehicle may provide many of the advantages of both electric and fossil fuel power storage while eliminating at least some of the 7494 _.
  • This "series” hybrid design has the advantage of reducing the number and weight of the electric batteries required to power the vehicle. Because the vehicle generates electrical power as it goes, it does not need as many electric batteries and also avoids a long battery recharge time. In addition, the gasoline engine can be operated under essentially constant conditions that can provide low exhaust emissions and low fuel consumption. But this "series" hybrid electric vehicle has some significant drawbacks. Its main drawback is that it is very inefficient in its use of gasoline. The process of converting the mechanical power produced by the gasoline engine into electrical power using a generator for powering the electric traction motor is relatively inefficient. This inefficient process wastes power.
  • the present invention provides a new parallel hybrid electric vehicle- design that delivers smooth, high power performance while decreasing harmful exhaust emissions and maximizing fuel economy.
  • a battery- powered electric motor assists the internal combustion engine.
  • the electric motor is controlled to output power under certain operating conditions to assist the internal combustion engine.
  • the electric motor provides a "load leveling" function that improves performance and driveability while maximizing fuel economy and reducing harmful emissions.
  • a controller can control the electric motor to assist the internal combustion engine during times when the engine is called upon to produce a rapid speed RPM change (for example, upon acceleration from low to high speed). It is during such rapidly changing conditions that the internal combustion engine runs least efficiently and produces a lot of harmful exhaust emissions. By controlling the electric motor to "load balance" the internal combustion engine during these rapidly changing conditions, it is possible for the controller to control the internal combustion engine to operate in ways that might otherwise be unacceptable from a performance or other standpoint.
  • the controller can supply the internal combustion engine with less fuel so it runs "leaner” during times when the electric motor is assisting the engine-increasing fuel economy and dramatically reducing harmful exhaust emissions.
  • the internal combustion engine operates very “lean”
  • overall vehicle performance doesn't suffer (and can actually be improved) because the electric motor provides power assist to make up for decreased internal combustion engine torque output.
  • the resulting power train operation is exceptionally smooth and powerful.
  • the acceleration curve is rapid and continuous. Depending on the particular system characteristics and system design and operating criteria, acceleration performance can be improved dramatically relative to a non-hybrid system while improving fuel economy and lowering harmful exhaust gas emissions.

Abstract

Nouveau véhicule électrique hybride parallèle dont la conception permet de réaliser des performances élevées de puissance sans sollicitation exagérée, tout en diminuant les émissions nocives d'échappement et en optimisant l'économie en carburant. Un moteur électrique assiste de façon stratégique le moteur à combustion interne. Ce dispositif peut améliorer la conduite du véhicule en la rendant agréable et sans à-coups. On peut limiter les émissions en aidant le moteur à tourner de manière adéquate. On économise du carburant en générant la puissance efficace nécessitée par le conducteur pour que le véhicule réponde à son exigence, tout en équilibrant la charge sollicitée du moteur à combustion interne. Quand le moteur à combustion interne tourne très efficacement avec une charge ou une décélération faibles, la source de puissance est chargée par le moteur jouant le rôle d'un générateur.
