Analysis of hybrid electric vehicle behaviour in real traffic conditions

This study is a new contribution to investigate the behaviour of the hybrid powertrains of light-duty vehicles in real traffic, dealing with fuel consumption,CO2 and NOx emission factors measured in real driving tests in Madrid and its surroundings. It is aimed to give numbers of the percentage of time of operative conditions when the vehicle is in zero emissions mode. Those periods are when the vehicle is stopped (does not travel any distance), is decelerating or braking; or is in only electric propulsion mode, therefore the relation between time and distance travelled is analysed.
