The invention discloses a multi-gear longitudinal hybrid electric vehicle driving system which comprises an engine, a planetary gear mechanism, a first clutch, a second clutch, a power generator, a driving motor, a gear transmission system, a first gear shifting mechanism, a second gear shifting mechanism and an output shaft. The second clutch is used for locking the planetary gear mechanism, the output end of the planetary gear mechanism is connected with the output shaft through the gear transmission system and the first gear shifting mechanism, and a motor shaft of the driving motor is connected with the output shaft through the gear transmission mechanism and the second gear shifting mechanism. According to the multi-gear longitudinal hybrid electric vehicle driving system, the stepless speed regulation hybrid driving and pure electric driving functions can be achieved within the whole vehicle speed range, the fixed speed ratio gears directly driven by the four engines and the fixed speed ratio of the two driving motors are combined, and better fuel economy is achieved; and gear shifting without power interruption can be realized.
