Analysis of 3 and 4 branch epicyclic transmission systems for Hybrid Electrical Vehicles using matrix method and TSA tool

This paper is focused on modeling and analysis of 3 and 4 branch epicyclic transmission systems for Hybrid Electrical Vehicles (HEVs) using the matrix method and transmission systems analysis (TSA) tool. The TSA tool is especially developed to analyse such systems. The application of the system to a typical hybrid electric vehicle driveline is modeled and a comparison of the performance characteristics of competing designs is discussed. In addition, the potential benefits of the 4 branch epicyclic system are presented.
