Mode confusion in driver interfaces for adaptive cruise control systems

摘要

In this study, we developed a new driver interface for an adaptive cruise control system that suppresses mode confusion, based on a formal method for analyzing the correctness and succinctness of the interface and information. In the finite-state transition model for the interface, the states were grouped into a set of modes, each of which consists of the states that transition to the same state for the same user-triggered event. To test the mode awareness of our new interface and compare it with the mode awareness of a conventional interface, a set of human-in-the-loop experiments were conducted in a simulated environment using a driving simulator.
