Our laboratory aims to realize a car society that is friendly to people and the environment through research on automobile collisions and ride quality. Human resources who can contribute to society by utilizing CAE (Computer Aided Engineering) as an evaluation and analysis tool for understanding collision phenomena and the comfort and discomfort of riding comfort, and by tackling issues (Practical learning) based on industry-academia collaboration. Aim for training.

Research on damage and repairability of vehicle structural members in low-speed collisions of automobiles
According to a survey of insurance claims paid by domestic automobile insurance by the General Insurance Association of Japan, the amount of economic loss due to a traffic accident over the past eight years has remained high at over 3.2 trillion yen annually. The amount of personal injury related to high-speed traffic accidents is declining due to the dramatic improvement in occupant protection devices (airbags, seat belts, etc.) and vehicle body frame design technology. On the other hand, the amount of physical loss related to low-speed traffic accidents (repair costs: parts costs, painting costs, wages, etc.) is increasing year by year. The purpose of this research is to create a technology for designing a car body frame that is cheap and easy to repair in low-speed collisions while maintaining the performance of high-speed collisions.
Research on technology for predicting changes in performance over time in automobile seat urethane
Urethane foam is often used as a shock absorbing material in the event of a traffic accident and as a cushioning material for seats. The seat is a part that the occupant is in constant contact with while riding, and among its components, the seat urethane has static performance related to maintaining the driving posture and sitting comfort, vibration damping during vehicle driving, and the degree of fatigue. It is an important component that determines the dynamic performance of the. It is generally known that this urethane undergoes chemical and physical changes such as crack formation, coloring, and changes in strength and elongation when exposed to the natural environment for a long period of time (changes in performance over time). The purpose of this research is to develop a performance prediction technology that takes into account changes in the performance of urethane foam over time.
Research on an analysis system that can evaluate a driver's physical driving ability
In Japan, which is facing a super-aging society that is unprecedented in the world, the elderly can safely and actively use automobiles (mobility) and participate in society to secure a working population of seniors for the era of 100-year lifespans. , we believe that sustainable economic revitalization will be possible. At the same time, it can be said that there is an urgent need to create technology to prepare for the arrival of such a new era in Japan. This research aims to clarify the characteristics of the physical characteristics of the elderly from the perspective of biomechanics, and to create a technology that enables the elderly to achieve the same driving ability as the young. This research is being carried out with the support of Keirin, a JKA subsidized project.
Research on V.R. system analysis system capable of quantitative neuroscience evaluation of misjudgment that causes erroneous operation by elderly drivers
In Japan, which is facing a super-aging population unlike any other in the world, a working population of elderly people can be secured for the era of 100-year lifespans through the safe and active participation of the elderly in society through the use of automobiles (mobility). , we believe that sustainable economic revitalization will be possible. Furthermore, we believe that the creation of technology to prepare for the arrival of such a new era in Japan is an urgent task. The purpose of this research is to create a technology that can neuroscientifically and behaviorally evaluate the instantaneous judgment characteristics of the elderly. This research is being carried out with the support of Keirin, a JKA subsidized project.
