Single-engine sanitation vehicle power system and power control method thereof

Abstract

A single-engine sanitation vehicle power system comprises an engine, an ISG motor and a PE controller. The engine is in transmission connection with a gearbox through the ISG motor and a clutch in sequence. The PE controller is internally provided with a loading instrument receiving module, a motor driving module, a current incoming processing module and a vehicle loading operation driving module. The input end of the loading instrument receiving module is connected with the output end of a loading controller. The output end of the loading instrument receiving module is connected with the input end of a vehicle loading operation device through the motor driving module, the ISG motor, the current incoming processing module and the vehicle loading operation driving module in sequence. When a sanitation vehicle needs to be operated, the ISG motor is controlled by the PE controller to generate electricity, and direct current generated by the ISG motor is converted into alternating current for driving a loading operation device to work. When the sanitation vehicle does not need to operate, the ISG motor is just used as a transmission shaft for transferring mechanical energy of the engine to the gearbox. According to the design, the structure and control are simplified, and the dead-weight of the vehicle, running noise and emission are lowered.

Description

technical field [0001] The invention belongs to the technical field of automobile power systems, and in particular relates to a single-engine sanitation vehicle heat dissipation system and a power control method thereof, which are suitable for simplifying structure and control, and reducing vehicle weight, running noise and emission. Background technique [0002] With the widespread application of sanitation vehicles, how to improve the efficiency of sanitation vehicles, reduce vehicle weight, driving noise, exhaust emissions and purchase costs has become a new research topic. Since the sanitation vehicle requires the fan to have a higher speed and a lower vehicle speed when it is working, there are two main trends in the sanitation vehicle on the market at present: one conventional mode is to use dual engines, and the chassis engine mainly drives the vehicle. The auxiliary engine mainly drives the movement of working parts such as fans and high-pressure water pumps. The dua...
