Study of a Hybrid Refuse Truck with City Driving Cycles

Refuse trucks are used in many communities for garbage collection and compression in China. This article introduces representative driving cycles of refuse trucks in multiple cities. System configuration is described first. Then, traditional pedal map, shift-pattern, and shift-point are used as basis to optimize energy utilization for specific hybrid configurations under refuse truck driving situation. Since AC power is used as source for garbage compression, to take advantage of such operating characteristics, engine start and stop technology can be a viable technology to improve fuel economy. Experiments are conducted to reach the conclusions.
