Problems solved by technology

The hybrid transmission system is mainly based on the current mature dual-clutch transmission technology and motor control technology. By changing gears, the drive motor and engine can work in the high-efficiency zone for a long time, which improves work efficiency, increases vehicle dynamics, and improves vehicle fuel efficiency. It is economical and maintains the driving pleasure of traditional vehicles, but the hybrid system has high R&D and manufacturing costs, high technical difficulty, high mass, and large volume, which makes it inconvenient to carry, and the electric motor cannot charge the battery when the engine is driving, and cannot drive all gears So it does not meet the shortcomings of power and economy requirements

The invention further discloses a vehicle. Through the arrangement of thefirst motor and the second motor, power interruption in the gear shifting process is avoided, and the power performance and the gear shifting mode switching smoothness are improved; and due to dual-motor hybrid power, the transmission efficiency is high, the power consumption is low, and the gear structure of the gear is simplified, so that the driving system is more compact in structure.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to a hybrid drive system and a vehicle. Background technique [0002] A HEV is a vehicle that uses multiple energy sources, usually a conventional engine (ICE) using liquid fuel and an electric motor using electrical energy to propel the vehicle. Hybrid vehicles can operate in a variety of drive modes, but have limited battery capacity and rely primarily on engine combustion for power. [0003] Most of the hybrid structures at this stage adopt the P2 hybrid mode, that is, the electric motor is placed on the input shaft of the transmission. The hybrid transmission system is mainly based on the current mature dual-clutch transmission technology and motor control technology. By changing gears, the drive motor and engine can work in the high-efficiency zone for a long time, which improves work efficiency, increases vehicle dynamics, and improves vehicle fuel efficiency. It is ec...
