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.
