The impact of drivers’ acceleration style on the vehicle energy performance: a real-world case study.

The present study investigates the impact of different acceleration styles collected from a sample of human drivers on the vehicle's energy performance in real-world trips. The variations in CO2 emissions according to different acceleration patterns are benchmarked to real-world trips from a driving campaign that involved 20 drivers on the same reference vehicle. The paper builds on a previous work that benchmarked the correlation between CO2 emissions and acceleration behaviour to the standard homologation Worldwide Harmonized Light Vehicles Test Cycle (WLTC). The current work extends the application to real-world conditions, modifying the acceleration events of real-world trips according to the driver's acceleration attitude and subsequently simulating the energy performance, specifically the CO2 emissions. The heterogeneity of the driver's acceleration style is characterised by the vehicle-Independent Driving Style metric (IDS), which represents the driver's acceleration aggressiveness. The results confirm a significant impact in CO2 emissions of the acceleration behaviour, leading to differences above 10% between the most timid (IDS=0.05) and most dynamic styles (IDS=1) when a consistent acceleration style is followed for the whole trip, in contrast with the 5% difference found when benchmarking to the WLTC cycle. The impact is substantially reduced (± 1 CO2 g/km) when considering the stochasticity of the human acceleration style.
