Abstract
A series type hybrid electric vehicle that controls an internal combustion engine, generator, and electric motor for reducing the load applied to the internal combustion engine when the internal combustion engine is restarted, lowers the thermal stresses to the internal combustion engine when the engine is turned off and is able to remove excess fuel when turning off the internal combustion engine.
Claims36
A method for adaptively controlling a series type hybrid electric vehicle including an internal combustion engine connected to a generator and at least one electric motor with the engine and generator selectively operated in various operation modes, comprising:
- operating the vehicle in a first mode in which internal combustion engine and generator are off and the motor propels the vehicle from power stored in the battery array;
- operating the vehicle in a second mode in which the internal combustion engine and generator are operating without restriction as to limiting vehicle discharges;
- and
- operating the vehicle in a third mode in which the operation of the internal combustion engine and generator are at least partially restricted to limit vehicle discharges.
A series type hybrid electric vehicle, comprising:
- an internal combustion engine connected to a generator;
- a battery array receiving current at least from the generator;
- a least one electric motor receiving current from the battery array, the motor propelling the vehicle;
- and
- a controller that selectively operates the engine and generator in various operating modes, including:
- a first mode in which the internal combustion engine and generator are off and the motor propels the vehicle from power stored in the battery array;
- a second mode in which the internal combustion engine and generator are operating without restriction as to limiting vehicle discharges;
- and
- a third mode in which the operation of the internal combustion engine and generator are at least partially restricted to limit vehicle discharges.
