Switching control in hybrid vehicle system based two wheeler

Abstract

This paper develops a test bed for a hybrid vehicle's power train along with a switching control methodology to address the time delay experienced in electrical switching between engine and motor power to achieve smooth power transmission to the wheels, thus reducing fuel consumption. A complete test bed for the power train is designed and fabricated. A conventional sequential-based switching control algorithm is developed to operate the system with a motor at low speeds and the engine at higher speeds, using the number of rotations per unit time as the switching parameter. The logged output is analyzed and the performance efficiency of the hybrid vehicle powertrain is compared against conventional internal combustion (IC) engines.
