A Study of Estimation method for Biological behavior of a Vehicle Driver using Steering Wheel Sensor System

本研究旨在减少因驾驶人行为而导致的交通事故，并发展一种对车辆驾驶人身心压力的评估方法。从驾驶员行为分析的角度出发，提出了一种由32个小压力传感器组成的方向盘传感器系统，该系统可以测量车辆驾驶员的抓握力和抓握模式。利用该传感系统对驾驶员的抓取行为和生物信号进行了测量，并对这些数据进行了对应分析。并通过实验和分析结果验证了所提出的驱动支护测量和估计方法的有效性。

This study aims to realize the reducing of car accident caused by driver's behavior and to development an estimation method for physical and psychological stress of the vehicle driver. The steering wheel sensor system which has 32 points of small pressure sensors and can measure for grasping forces and patterns of vehicle driver had proposed from the viewpoint of driver's behavior analysis. By using this sensor system, grasp behavior and biological signals of driver were measured and correspondence analysis for these data has been conducted. And, the validity of the proposed measurement and estimation method for the driving support also has confirmed through the experiments and analysis results.
