The invention discloses a longitudinal hybrid electric vehicle driving system which comprises an engine, a planetary gear mechanism, a power generator, a driving motor, a gear transmission mechanism, a gear shifting mechanism and an output shaft, and a gear ring of the planetary gear mechanism serves as the output end of the planetary gear mechanism to be connected with the output shaft. A motor shaft of the driving motor is connected with the output shaft through a gear transmission mechanism and a gear shifting mechanism, and the gear shifting mechanism can enable the driving motor to achieve two gears capable of being switched. The gear transmission mechanism comprises a parallel shaft and a plurality of gears, the parallel shaft and the output shaft are arranged in parallel, and the gear shifting mechanism is arranged on the parallel shaft. According to the longitudinally-arranged hybrid electric vehicle driving system, stepless speed regulation of the engine can be achieved, and the driving motor and the output of the planetary gear mechanism can form parallel driving; the driving motor can achieve gear shifting without power interruption, in the gear shifting process, the torque output by the engine through the planetary gear mechanism can be kept in a stable state, and the driving requirement of the vehicle is met.
