Usability of Display-Control Switches for In-Vehicle Information Network System

In order to cope with the rapid development of the ITS and the future information society, it has become necessary to build an in-vehicle information network system with high expandability which is capable of safely providing an increasing volume of information to passengers. This networking will not only promote the standardization of various instruments, but will also make it possible to integrate SW and display functions which are attached to those individual instruments and to make them more independent, thereby allowing the existing instruments to be more clearly visible and more easily operable.

In this paper, the relationship between visual-recognition time and operation time in the display-operation system (as a human interface with the center cluster section when the above-mentioned network was designed) will be evaluated using a simulator. In addition, after comparing the typical existing system with the proposed one, a configuration of a system capable of satisfying both driver safety and system expandability will be proposed.
