Optimal Control Strategy of Hybrid Electric Vehicle

Abstract

This thesis deals with the very progressive branch of the automotive industry, hybrid and electric vehicles. Based on the configuration the hybrid and electric vehicles are using an electric motor for the converting of the electrical energy into the mechanical energy, which is used for the vehicle moving. The main limit of these vehicles especially pure electric vehicles is limited range. One way how to extend the range is to add other battery cells, which increases the price of the vehicle, or to use optimization methods in cooperation with advanced driver assistance systems. The proposal of the optimization method is the main goal of this thesis. The results of the optimization method are compared with the real driving cycle made by äkoda Rapid EV provided by äkoda auto a.s. This thesis also deals with design of control part of DC/DC power converter for super-capacitor. Super-capacitors can be used in the hybrid and electric vehicles as a temporary storage of the electrical energy if a recuperation is needed
