Abstract

The invention discloses a fatigue driving fusion detection method based on soft computing, which can detect the fatigue driving of the driver and is characterized in that: the fatigue driving is detected in fusion mode through two aspects which include two facial characteristics for directly indicating the fatigue state of the driver and two vehicle behavior characteristics for indirectly indicating the fatigue state of the driver, wherein the two facial characteristics respectively are frequent blinking and yawning, and the two vehicle behavior characteristics respectively are abnormal vehicle lane deviation and abnormal steering wheel rotation; the invention utilizes the TS fuzzy neural network to recognize fatigue driving, adopts abstraction clustering for the optimized recognition of the network structure, and determines the number of fuzzy rules of the fuzzy neural network and the initial values of the relevant network parameters; genetic algorithm is utilized to train and optimize the network parameters, and determine the optimum network parameters; the TS fuzzy neural network is utilized to detect the fatigue driving of the driver in real-time according to the optimum network parameters and the four fatigue characteristic parameters.
