Fuel Consumption Optimization Analysis of a Hybrid Commercial Vehicle
The development trend of new energy for commercial vehicles is obvious.Pure electric and plug-in hybrid electric vehicle(PHEV)models are increasing,hybrid electric vehicle(HEV)commercial vehicle models are less,and HEV commercial vehicle fuel consumption research is less.Based on the high-efficiency engine and 1-speed rear-drive hybrid transmission,this paper develops a hybrid system suitable for light commercial vehicles,and carries the hybrid system on a 3.5 t light commercial vehicle.Through the test method,the fuel consumption performance of the light commercial vehicle is analyzed and optimized on the vehicle test bench.The results show that through the optimization of vehicle control strategy and engine fuel consumption,the fuel consump-tion of hybrid light commercial vehicle is reduced from 8.9 L/100 km to 8 L/100 km,and the fuel consumption of vehicle is reduced by 10%.Through optimization,the vehicle has reached the development goal.The vehicle control strategy and engine fuel consumption are important factors affecting the fuel consumption of light hybrid commercial vehicles.
