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. |
