Fuel economy validation of the smart microhybrid system for used cars

We developed a smart microhybrid system for used cars to improve fuel efficiency via the OBD-II interface. The proposed smart microhybrid system can accurately measure the amount of fuel that is saved by stopping engine idling and estimates the amount of fuel that is consumed when the engine begins to start. It automatically determines when is optimal to stop or start the engine using various driving status. The system was implemented and tested in a used car. Experimental results show that it outperforms conventional cars not equipped with the smart microhybrid system in fuel economy. We will massively reduce CO2 by using smart microhybrid systems and prove the possibility of the CDM (clean development mechanism) project.
