Abstract: 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.
