[Title of award-winning research]
Rollover-prevention fastest automatic cornering based on XNUMXD center-of-gravity detection theory

[Outline of Awards]
　A student team from the Graduate School of Marine Science and Technology graduated from the finals of the "2023 Student Safety Technology Design Competition" in Japan (sponsored by the Ministry of Land, Infrastructure, Transport and Tourism), and was held in Yokohama from April 5 to 4, 3. , participated in international competitions (sponsored by the U.S. Department of Transportation Road Traffic Safety Administration, Ministry of Land, Infrastructure, Transport and Tourism, and Ministry of Economy, Trade and Industry) as a representative of Japan and won the championship.
　This competition is one of the programs in which students participate in the "ESV International Conference" on automotive safety technology.Teams of students from each university and graduate school present their own technical ideas for solving safety problems, and compete in terms of their novelty, development potential, and practicality.Since the presentation will be done using a scale model, not only ideas but also technical backing and sufficient verification are required.

[Details of award-winning research]
　Until now, the three-dimensional center-of-gravity detection theory was limited to quantifying the risk of rollover and displaying and notifying the driver.This time, we created a scale model that combines this theory with autonomous driving.This model was then driven automatically by remote control, increasing speed during cornering and applying the three-dimensional center-of-gravity detection theory in real time to quickly estimate the maximum rollover acceleration.And the centrifugal force applied to the center of gravity of the vehicle in real time (in the industry, horizontalG) was measured and compared with the rollover limit acceleration.and sidewaysGWe built a program that repeats the process of decelerating when the is about to reach the rollover limit acceleration, and accelerating again when the rollover is prevented.With this system, the scale model was able to continue rounding corners at the fastest speed possible without overturning.Furthermore, in order to actually prove that the theory is correct, when the automatic operation was canceled in the above state and the speed was slightly increased in manual operation, the scale model vehicle overturned in the blink of an eye.A visitor tried this and the result was the same.The position of the cargo loaded on the scale model can be freely changed by those who try it.Even if I changed the position of the center of gravity at will, the result was the same, maintaining the fastest state without overturning.

Yu Kai Lun (Team Leader)
"Lead and captain our team,ESVI am very honored to have won the Student Safety Technology Design Competition.Knowing that most of the opponents were from famous Western universities, I was very nervous because my mother tongue is not bob博彩公司_申博体育在线-投注*官网.As presenters/demonstrators, we have practiced a lot to introduce our research to judges and audiences.I was very happy when I learned that I had won the prize, but I was confident in my research results, so I was not too surprised.I would like to thank the entire team for their dedication and hard work in making this achievement possible.Furthermore, we must not forget that this is the result of the guidance and support of Dr. Yutaka Watanabe.We hope that our research results will be put to practical use worldwide as soon as possible.”

Xu Yao
“When I look back on my journey so far, I am deeply moved. From being a finalist in the Japan competition to the world competition, I am grateful for the teamwork, the guidance of the teachers, and the advice of the experts. I believe that this has led to our success.By applying our knowledge of the ocean to improve vehicle safety, new technological developments and approaches will be born, and I feel that we can contribute to the realization of a safer motorized society. What I found rewarding was the surprise that this technology was so attractive in the world.The teamwork of the professors who supported us for a long time until we received this award. I am deeply grateful for the support.I would like to use this experience to continue to make efforts to develop the automotive safety field.”

Onodera Nozomi
“I am very honored to receive the highest evaluation in such a global arena. I am also proud that the Japanese team was able to win the championship for the first time in this tournament, which is held in Japan. Many people, regardless of nationality or occupation, shared their understanding and advice on the technology that we have been researching, and it was a valuable experience that motivated us to further develop in the future.”
