Study on the Influences of Vehicle Braking Failure on Human’s Physiological and Psychological Behavior

Abstract

By studying subjects’ skin conductance (SC), EMG, pulse and heart rates under the condition that vehicle braking system is of partial failure, complete failure, single circuit failure, or normal condition, this study examines whether there are significant changes of the physiological and psychological behavior of the drivers under the condition of vehicle braking system failure and normal driving. With the method of repeat measurement of variance analysis, 6 subjects are tested, including experienced drivers and inexperienced drivers, who are equipped with apparatus testing SC, EMG, pulse and heart rates before the experiment, and subjects’ parameters under the condition of vehicle braking system failure and normal driving are both recorded. Experimental results show that the braking distance, braking time, average braking deceleration and ECG index can reflect the risk of vehicle braking performance and the level of driver’s risk perception. The results of this study provide experimental data supports for defect determination of automobile braking system failure.
