The impact of real driving on vehicle CO₂ emissions

On-road (real) driving of a conventional vehicle having free gear-shift strategy and driving style, non-zero positive altitude gain, and uncontrolled ambient conditions is expected to produce different emissions values, including CO 2 , in respect to those produced in a controlled laboratory experiment following a standardized velocity profile. This paper aims to investigate the impact of driving style characterized by driving dynamics on CO 2 emissions of a passenger car equipped with an internal combustion engine. The study is based on recorded on-road trips of a passenger car that are postprocessed using the EU real driving calculation procedures. Selected segment trips of urban, rural and motorway driving are used as input for a detailed vehicle model developed in LMS Imagine. Lab AMESim in order to assess the impact of real driving on vehicle CO 2 emissions.
