Intelligent cruise control (ICC) can contribute not only to driving comfort but also to driving safety; an inadequate human-machine interface would easily decrease the safety effect of ICC. This paper first describes the importance of human-machine interface in such autonomous driving systems. In order to analyze human-machine interface, a simple reliability analysis model of human-machine system has been proposed. Secondly, Preview Distance Control (PDC), trade name of Mitsubishi's ICC, and its users' survey results have been introduced. These results show that the users are satisfied with the current human-machine interface of PDC. Finally, an ICC system with automatic brakes has been proposed, which is an advanced system of PDC with satisfactory human-machine interface.
