N2 - This file contains the data and the Matlab script used to analyse and generate the figures for the manuscript named: Creating the illusion of sportiness: Evaluating modified throttle mapping and artificial engine sound for electric vehicles. Published in the Journal of Advanced Transportation.<br>Specifically,- 'Matlab Analysis' folder contains the data and the Matlab script for the analysis. The script named "Sportiness_DrivingSimulator_Analysis_clean.m" automatically generates all figures and tables used in the journal paper.- 'Videos' folder contains an example video (and sound) of each condition used the experiment.- 'Additional result tables' folder contains 3 additional result tables- 'Senso_pedals_info' file contains some information about the driving pedals used in this driving simulator experiment.<br>Abstract of journal paper:<br><p><i>Modern
computerized vehicles offer the possibility to change vehicle parameters with the aim of creating a novel driving experience, such as an increased feeling of sportiness. For example, electric vehicles can be designed to provide an
artificial sound, and the throttle mapping can be adjusted to give drivers the
illusion that they are driving a sports vehicle (i.e., without altering the
vehicle’s performance envelope). However, a fundamental safety-related question
is how drivers perceive and respond to vehicle parameter adjustments. As of
today, human-subject research on throttle mapping is unavailable, whereas
research on sound enhancement is mostly conducted in listening rooms, which
provides no insight into how drivers respond to the auditory cues. This study investigated how perceived sportiness and driving behavior are affected by
adjustments in vehicle
sound and throttle mapping. Through a
within-subject simulator-based experiment, we investigated (1) Modified
Throttle Mapping (MTM), (2) Artificial Engine Sound via a virtually elevated
rpm (AES), and (3) MTM and AES combined, relative to (4) a Baseline condition,
and (5) a Sports car that offered increased engine power. Results showed
that, compared to Baseline, AES and MTM-AES
increased perceived sportiness and yielded a lower speed variability in curves. Furthermore, MTM and MTM-AES caused
higher vehicle accelerations than Baseline during the first second of driving
away from a standstill. Mean speed and comfort
ratings were unaffected by MTM and AES. The
highest sportiness ratings and fastest driving speeds were obtained for the
Sports car. In conclusion, the sound
enhancement not only increased the perception of sportiness but also improved
drivers’ speed control performance, suggesting that sound is used by drivers as
functional feedback. The fact that MTM did not affect the mean driving speed
indicates that drivers adapted their ‘gain’ to the new throttle mapping and
were not susceptible to risk compensation.</i></p><br><br>
