摘要
In order to achieve best dynamic performance of vehicle, a parameter matching method was proposed for vehicle power train. Firstly, the speed ratio of gear box was optimized based on functional analysis theory. Then taking the speed ratios as functional argument, a general functional form of acceleration time was established. The numerical and optimal solutions of speed ratios were obtained based on Euler finite differential method in calculus of variations. Finally, to analyze acceleration performance in different control strategies, a dynamic model of continuously variable transmission was established. Simulation results show that, the acceleration time of 6~60 km/h can decrease by 8.79% in 100% throttle opening based on the functional control strategy, verifying the feasibility of the functional analysis method for optimal ratio control problems in theory.
