A hybrid electric drive train for a motor vehicle comprises an engine with a drive shaft, an electric motor operable of motoring and generating, a differential transmission, and a multi-stage transmission with two input shafts and at least one output shaft. The differential transmission includes a planetary gear set, a clutch and a brake. The planetary gearset has a first element connected to the motor and the second input shaft of the transmission, a second element connected to the engine shaft, and a third element connected to the first input shaft of the transmission. The clutch is located between any two elements of the planetary gear set, and the brake is connected to the engine shaft. The transmission has a plurality of gearsets, and the driving gears of odd-numbered gearsets are mounted on the first input shaft while the driving gears of even-numbered gearsets are mounted on the second input shaft. The engine shaft can achieve every gear ratio of the gearsets. In addition, the engine shaft can also achieve a plurality of derivative speed ratios.
