Power drive system and vehicle

A power drive system, wherein the power drive system has seven forward gears, and the power drive system comprises:

• an engine;
• a plurality of input shafts, the engine being configured to selectively engage at least one of the plurality of input shafts, and a gear driving gear being arranged on each of the input shafts;
• a plurality of output shafts, a gear driven gear being arranged on each of the output shafts, the plurality of gear driven gears correspondingly meshing with the plurality of gear driving gears, a reverse output gear being idly arranged on one of the plurality of output shafts and a reverse-gear synchronizer for engaging with the reverse output gear further being arranged on the output shaft;
• a reverse shaft, the reverse shaft being configured to be linked with one of the plurality of input shafts and the reverse output gear;
• a motor power shaft, a motor-power-shaft first gear and a motor-power-shaft second gear being idly arranged on the motor power shaft, and a motor power shaft synchronizer located between the motor-power-shaft first gear and the motor-power-shaft second gear being further arranged on the motor power shaft, wherein the motor-power-shaft second gear is configured to be linked with one of the gear driven gears;
• and
• a first motor generator, the first motor generator being configured to be linked with the motor power shaft.
