A Fuzzy Control Massage Seat Based on Momentum Index for Combating Driver Fatigue

摘要

In this study,a fuzzy control massage seat for combating driver fatigue was developed.First,we combined actual driving performance with tendency index to predict the tendency of driver fatigue,and found that the 12 periods KDL (stochastic oscillators) of momentum of speed and steering wheel angle are better for detecting driver fatigue.Second,a fuzzy control technology was used to develop the fatigue driving detecting system,which integrates fuzzy logic reasoning and neural network learning.Finally,the fatigue driving detecting system was further developed to control massage seat for combating driver fatigue.The experiment results showed that the fatigue driving detecting system correlated well with subjective fatigue ratings had good effect of fatigue detection,and could efficiently control massage seat to alert subjects for keeping concentration on traffic conditions.The massage seat could reduce marginally some symptom of fatigue.
