A hybrid electric vehicle having a selective zero emission mode, and method of selectively operating the zero emission mode

摘要

A series type hybrid electric vehicle 10 that controls an internal combustion engine 300, generator 310, and electric motor 50, 60 for zero emissions within a zero emission zone 440. As the vehicle 10 approaches the zero emission zone 440, the internal combustion engine 300 and generator 310 increase the electrical charge of the battery array 30 to a predetermined level. The internal combustion engine 300 and generator 310 are eventually turned off to prevent emissions from entering the zero emission zone 440. As the vehicle 10 leaves the zero emission zone 440, the internal combustion engine 300 and generator 310 are warmed to a predetermined level for a full capacity operation. When the internal combustion engine 300 and generator 310 reach the predetermined level, they operate at full capacity to bring the electrical charge of the battery array 30 to a predetermined electrical level.
