In order to recognize driving fatigue, this paper proposed a fatigue detection method based on wavelet characteristics and Long Short-Term Memory (LSTM) neural network classifier. Two kinds of EEG signals (non-fatigue and driving fatigue) were collected in the real driving environment. The EEG signals were decomposed by wavelet, and the statistical values, energy values and relative energy values of four wavelet coefficients were calculated as the characteristic data, which were used for classification training and test of the LSTM neural network. The results of experiment show that the classification performance of LSTM neural network gradually improves with the increase of the number of channels involved in constructing characteristic data. Especially, in the scheme of 14 channels, the average classification accuracy is about 96.1%.
