Controller Design for Optimizing Fuel Consumption of Hybrid Electric Vehicles

—A Model-free Approach Based on Simultaneous Perturbation Stochastic Approximation—

Abstract

This paper addresses the benchmark problem of controller design of hybrid electric vehicles, which has been recently proposed by JSAE and SICE. As a solution, we propose a model-free design method based on the simultaneous perturbation stochastic approximation. The proposed method achieves approximately 44 percent improvement compared with the existing controller.
