Abstract

The invention discloses a power driving system for a vehicle and the vehicle. The power driving system comprises an engine, multiple input shafts, multiple output shafts, a motor power shaft, a firstelectric generator and a second electric generator, and the engine is connected with at least one of the multiple input shafts; the motor power shaft is sleeved with a motor power shaft first gear anda motor power shaft second gear, a synchronizer is arranged between the motor power shaft first gear and the motor power shaft second gear, and the motor power shaft first gear and the multiple output shafts are in linkage with a differential mechanism, and the second gear is in linkage with one gear driven gear; the first electric generator is in linkage with the motor power shaft; the second electric generator and the engine are located at the input side of a first clutch device, and the second electric generator can utilize part of power output by the engine to conduct parking power generating when the vehicle parks. In this way, the power driving system is rich in driving mode, high in driving efficiency and high in parking power generating efficiency.

Description

Technical field [0001] The present invention relates to the field of vehicle technology, in particular to a power drive system for a vehicle and a vehicle with the power drive system. Background technique [0002] With the continuous consumption of energy, the development and utilization of new energy vehicles has gradually become a trend. As one of the new energy vehicles, hybrid electric vehicles are driven by engines and / or electric motors and have multiple modes to improve transmission efficiency and fuel economy. [0003] However, among the related technologies known to the inventors, some hybrid electric vehicles have few driving modes, low driving transmission efficiency, and low power generation efficiency during parking and power generation conditions. Summary of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the present invention proposes a power drive system for a veh...
