A tool for generating optimal control laws for hybrid electric powertrains*

This paper describes the development of a tool for automatic generation of optimal power management strategies. Given the user inputs, which are dynamic vehicle model, driving cycle and optimization criterion, the tool first produces a simplified powertrain model in the form of static maps, before dynamic programming is used to find an optimal torque split which minimizes the chosen criterion. The tool does not require a transparent vehicle model, which makes it possible to work on models hidden for intellectual property reasons.
