Abstract:

A human-machine interface (HMI) interface design method was proposed based on the dynamic Trust Theory to improve the safety at autonomous driving takeovers. The trust levels were classified into three categories: the insufficient trust, the calibrated trust, and the over-trust. A hierarchical situation-aware transparency (SAT) interface was designed, and an empirical investigation was conducted in high-speed lane-changing scenarios. The eye-tracking data were recorded and analyzed by aligning event lock timing (ELT) with critical time windows (CTW), and the subjective evaluations were carried out through questionnaires. The results indicate that the interface optimized through the trust mechanism reduced drivers' takeover response time (RT) by 26.71% compared to the original interface, thereby enhancing safety margins during critical moments; it also decreased the incidence of delayed takeovers from 23.7% to 9.2%, reducing potential collision risks. Therefore, these results would provide a methodological reference for the engineering application of intelligent cockpit HMIs.
