Tracked vehicle hybrid drive system is a kind of electromechanical transmission system and equipment.In order to improve the efficiency of system design and modeling,an automated modeling method was proposed for a series-parallel tracked vehicle hybrid drive systems.Based on the modeling of a power combining device and a power convergent device,the automated modeling principles were illus-trated and the automated modeling rules and the screening conditions were further proposed.Then the fi-nal model equation eliminated intermediate quantity was derived.With the automated modeling method,some tracked vehicle hybrid drive systems were modeled in Simulink to validate the method.The auto-mated modeling processes were programmed.And as an application demonstration for the automated modeling,optimal configuration seeking was described.The results show the method may build the mod-el and screening the configuration automatically,which is a powerful method for rapid and automated modeling of tracked vehicle hybrid drive systems.
