Examination of Experimental Method to Extract Characteristics of Lower Limb Movement in Emergency Braking Operation

The purpose of this study is to clarify the driving behavior and reaction pattern peculiar to the elderly. In this paper, we conducted a brake operation experiment with five young people, and aimed to create an evaluation index and an experimental method that can extract the characteristics of emergency brake operation from pedaling force and lower limb movement. The results showed that in order to operate the brakes strongly and quickly, the knee was firmly flection, and then the pedaling force was increased when the knee was extended. Furthermore, it was shown that if the brakes were operated without moving the ankle joint, the operation would be quicker.
