Japan has a higher rate of rear-end collisions than any other kind of traffic accident and the causes of rear-end collisions were investigated. Accident statistics were used to conduct a statistical traffic accident analysis while a questionnaire was used to conduct a detailed traffic accident analysis and simulation was then used to perform traffic accident analysis. The results of the traffic accident analysis suggested that many of these accidents were caused by lack of attention during daily driving. Research was conducted to determine what kind of collision avoidance systems would be effective. A system was developed that is effective in reducing the collision velocity during rear-end collisions by making up for driver delays in recognition, judgment and operation by means of brake control and external sensing technology using millmeter wave radar sensor. This paper will discuss the testing and development of this new system.
