Abstract：[Objective]In order to quantitatively work out operating parameters and relation of parts of multi-power system coupled with planetary gears,a mathematical mapping analysis method was proposed.[Methods]The method was discussed by analyzing the hybrid system coupled with planetary gears of a truck;the kinematic and mechanical relations of parts of the system were deduced;a mathematical map was constructed with Matlab software;the switching order of modes and the path planning in start-up acceleration were quantitatively analyzed;the optimal cruising fuel consumption under different slopes and speeds was quantitatively analyzed;based on the above analysis,three system architecture optimizations were proposed,and compared to the original system in performance with simulation.[Results]The switching order of modes,the path planning and the optimal fuel consumption point under cruising conditions can be intuitively and quantitatively figured out.The optimizations are verified by simulation to have a certain effect in performance improvement,which is useful for the development of control strategy and calibration of the system.
