ENHANCING DRIVER ACCEPTANCE OF ADAPTIVE CRUISE CONTROL IN DYNAMIC SIMULATORS
Thursday 21 May 2026 14:20
The study examines how tuning tilt coordination affects user acceptance of Adaptive Cruise Control (ACC) in the DIM400 dynamic driving simulator of Politecnico di Milano. Using a within-subject design, tilt gain settings were tested during acceleration and braking tasks. Results combine objective performance metrics with subjective ratings of realism, comfort, and trust. Results show that higher tilt gains improve the physical fidelity of simulated motion but can introduce perceptual conflicts when exceeding human sensitivity thresholds, leading to discomfort and reduced acceptance. Conversely, the absence of tilt limits the perception of sustained acceleration. A moderate tilt gain provides the best balance, ensuring realistic and comfortable motion cues. Overall, the results demonstrate that perceptual coherence plays a more critical role than physical accuracy alone, providing useful guidance for improving the reliability of simulator-based ACC evaluations.
