Abstract
A system and method for providing parallel power in a hybrid-electric vehicle. The system includes a compact motor coupled to the input shaft of the vehicle's transmission. Advantageously, the compact motor and the engine use the same drivetrain. Both the compact motor and the engine are able to apply power to the portion of the drivetrain from the transmission to the wheels. Since the motor is compact and does not require a separate drivetrain, the parallel power system can be installed in an otherwise conventional vehicle without packaging difficulties.
