A large, gas-electric hybrid power drive system and control strategy road sweeping vehicles

The present invention discloses a power drive system for large-scale gas-electric hybrid car and road sweeping control strategy. A power driven sweeper hybrid system large as: the engine power is transmitted via the transmission, by the power switch between the operating system and the traveling system power means so as to switch, one end connected to the traction battery charger 220V, the other end is connected to the motor, switching means coupled to the driving power of the motor system is switched by an engine through a torque coupler and power output to the drive wheels. With the present system, a power driving system, a power sub-system only an engine power corresponding to the size of the original car engine, the engine can work in the cleaning and transition modes at higher loading rates, fuel economy and emissions It has been significantly improved.
