ABSTRACT:
A hybrid electric vehicle powertrain is disclosed. A countershaft transmission in the powertrain delivers power from an engine through countershaft gearing. Electric power from a single motor-generator complements engine power and may drive front traction wheels. Regenerative power is recovered during power delivery to rear traction wheels.
