The Effect of Tactile Prompts During the Takeover Process of Autonomous Driving

Abstract: Autonomous driving technology is a key approach to enhancing road traffic safety and efficiency. Autonomous vehicles operate at a semi-autonomous level, necessitating driver intervention in certain situations. When the autonomous driving system encounters an emergency and issues a takeover request warning, it is imperative for the driver to promptly, safely, and smoothly assume control of the vehicle within the prescribed reaction time. During driving, auditory and visual channels are often occupied, which may lead to missed takeover information delivered through these modalities. Tactile signals emerge as an effective alternative to address this issue. This study utilizes a driving simulator to replicate driving scenarios and investigates the impact of tactile takeover signals on driver takeover efficiency. Additionally, subjective questionnaires were administered to assess drivers' psychological perceptions. The results demonstrate that tactile signals can effectively enhance driver takeover efficiency and are favorably received by drivers.
