Abstract: This article takes an automated mechanical transmission (AMT) vehicle model in the coal transportation market segment as the research object, and builds a complete vehicle simulation model based on AVL Cruise and SPA software. Through big data analysis of the Internet of Vehicles, user personas are established from the perspectives of roads, vehicles, and people, clarifying user operating conditions and typical gear-shifting scenarios. The optimization direction of gear-shifting performance under different scenarios is analyzed, and optimized gear-shifting sequences and gear-shifting MAP are customized based on users' actual operating scenarios. Gear-shifting calibration parameters are obtained through desktop calibration optimization and economic simulation. The simulation results show that there is no increase in fuel consumption while driving performance scores are improved. Real vehicle testing simulates gear-shifting scenarios for verification. Under constant throttle opening acceleration conditions, the vehicle acceleration time is improved by 3.6%. The gear-shifting strategy meets design expectations and can balance economy and driving performance in typical gear-shifting scenarios.
