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.

Abstract: A series type hybrid electric vehicle and method including a generator set having an internal combustion engine and a generator, a battery array and at least one electric motor includes a controller for controlling propulsion of the vehicle. The controller generates a second signal having a value proportional to the value of a first signal, indicative of user demand, and indicative of a demand of the at least one electric motor, determines if the value of the first signal is larger than the value of the second signal, increases the value of a command signal to the at least one electric motor, if the value of the first signal is not larger than the value of the second signal, and decreases the value of the command signal, if the value of the first signal is larger than the value of the second signal.

Abstract: A series type hybrid electric vehicle that controls an internal combustion engine, generator, and electric motor for zero emissions within a zero emission zone. As the vehicle approaches the zero emission zone, the internal combustion engine and generator increase the electrical charge of the battery array to a predetermined level. The internal combustion engine and generator are eventually turned off to prevent emissions from entering the zero emission zone. As the vehicle leaves the zero emission zone, the internal combustion engine and generator are warmed to a predetermined level for a full capacity operation. When the internal combustion engine and generator reach the predetermined level, they operate at full capacity to bring the electrical charge of the battery array to a predetermined electrical level.

Abstract: A series type hybrid electric vehicle including a generator set having an internal combustion engine and a generator, a battery array and at least one electric motor includes a controller for maintaining a state of charge of the battery array within a control limit. A controller of the vehicle determines if the vehicle is in one of a plurality of forward driving modes, compares a state of charge of the battery array to an upper control limit associated with a forward driving mode, decreases generated by the generator, if the state of charge is equal to or greater than the associated upper control limit, and increases the power generated by the generator, if the state of charge is less than the associated upper control limit.
