A great deal of research and development work has been carried out on ITS technology in recent years, and some commercial productions of these systems are now underway. Above all, adaptive cruise control (ACC) attracts a great deal of public attention as a fundamental driving control system.

Nissan started introducing ACC in 1999, and the number of Nissan’s ACC vehicles in operation in various markets has grown. Especially, at the market in Japan, it has been installed in a variety of vehicles, from luxury to the medium-size segments. This broad range of vehicle types enable a more in-depth study of factors related to ACC use and operation.

As we work to make ACC more prevalent, it is increasingly important to determine the actual market response to ACC. In order to determine that, we conducted a survey of Japanese ACC customers, and received not only very high evaluations of our system in terms of overall satisfaction and future purchase intention, but also valuable feedback to use as a reference for future development.

This paper explains the survey, summarizes the results, and discusses areas for additional study and consideration in the field ofACC.
