RESUMO
Vehicles are an important source of air pollutants and greenhouse gases. Their emissions have been controlled since the 1970s by laboratory tests but there are often found divergences to real-world emissions. Real driving emissions procedure is in implementation in many countries, for evaluating vehicles closer to actual operation. In order to reduce the dispersion of the results, some dynamic parameters, such as speed, acceleration, and CO2 emissions, are controlled; however, sometimes they are into the limits but divergences remain. This paper has the goal of applying VSP as an additional parameter for improving the evaluation of the vehicle dynamics, because it can better represent the engine power required for running as well as the road grade influence.
