| 摘要 |
This invention discloses a vehicle driving system and energy control methods. The vehicle driving system includes a DC-DC converter 10 coupled to a DC bus. The DC-DC converter 10 is coupled to the first and second energy storage devices 31,32, a DC-AC 40 coupled to the DC bus, an electrical machine 50 coupled to the DC-AC inverter, and an energy management control system 60. The energy management control system 60 produces energy distribution ratio between the first energy storage device 31 and the second energy storage device 32 based on the operating status of the motor vehicle and the load, to satisfy the vehicle driving energy requirements of the system, while making the vehicle driving system be better able to work in a variety of driving conditions. The vehicle driving system of this invention has higher efficiency and better robustness. |
