The Power Impact of Electric Power Assist in Hybrid Vehicle

Open access


The current interest in the development of hybrid vehicles is a response to serious effects of road transport on the environment over recent years. In addition, vehicles equipped with this type of drive combine the advantages of a conventional diesel engine and electric motor. This results in higher system efficiency while reducing emissivity.

This work seeks to demonstrate the effect of electric power on the total power of a hybrid vehicle. The research on the chassis dynamometer (MAHA LPS 3000) of the hybrid sports car, Honda CRZ, has been performed in three modes of operation: normal, economical and sport. The obtained results are presented in the form of graphs of external engine characteristics, where the influence of electric power on the system is visible.

The tested vehicle is equipped with sixth version of Honda’s Integrated Motor Assist (IMA) technology, which is the crucial system, assisting the combustion engine in order to provide higher performance and better fuel economy.
