Fuel economy and exhaust emission test method for HEVs - application of the linear regression method

摘要

This report describes the linear regression method as a fuel economy and exhaust emission test method for HEVs. The test results demonstrated that the fuel economy correction factor increases with a decrease of vehicle speed. ΔSOC affects the regenerative energy and diesel HEVs' exhaust emissions. The method can be applied to capacitor HEVs, and the effect of the 12V battery on the electricity balance of the main battery is negligible.
