Computer simulation for the design of authority in the adaptive cruise control systems under possibility of driver´s over-trust in automation

It is often said that humans must be maintained as the final authority over automation. However, that does not necessarily mean that human must be maintained as the final authority at all times and on every occasion. Design of authority is crucial for automobile, especially when there is possibility that the driver becomes complacent by trusting the automation excessively and when available time for safety control or information for situation understanding is limited. This paper gives a computer simulation method for analyzing the complacency effect and for investigating the efficacy of the trading of authority, by taking as an example the design of safety control schemes for driving with the adaptive cruise control systems.
