Reclined Posture for Enabling Autonomous Driving
As the future of mobility develops, automated vehicles (AV) will change road transportation and promise an improved quality of life. Within this development, however, the primary weakness, is the human per se. Due to physiological thresholds, many occupants react by developing symptoms of motion sickness (MS) when performing non-driving related tasks (NDRTs). This work describes approaches essential to mitigating MS with respect to interior design. Therefore, a real test-driving experiment with 25 volunteers was carried out at a test track in Sindelfingen. The effects of backrest angle and sitting direction were observed in consideration of predetermined NDRTs. The analysis showed that a reclined backrest angle leads to a significant (p < 0.0001) decrease in MS. Furthermore, the effect of seat direction appears likely to be less significant than the effect of backrest rotation. A second experiment was conducted on the Mercedes-Benz Ride Simulator in order to identify the acceptance of innovative sitting positions.
