The invention discloses a driving electroencephalogram signal recognition method based on a multi-domain asymptotic convolutional neural network, and relates to the field of electroencephalogram intelligent recognition. The method mainly comprises the steps of electroencephalogram (EEG) acquisition, frequency domain feature and spatial feature extraction, and variable asymptotic convolutional neural network modeling, recognition and classification. After the collected EEG signals are preprocessed, frequency domain features are obtained through fast Fourier transform (FFT) processing, and spatial features are obtained through common spatial pattern (CSP) processing. All frequency band features are stacked, an input matrix is constructed and input to the constructed variable asymptotic convolutional neural network model, strategies used in different stages are different, and recognition classification about five driving behaviors is obtained. According to the method, the frequency domain-space features and the variable asymptotic convolutional neural network model are combined, and the global features of the EEG signals are more concerned, so that the model classification capability is remarkably improved, and the EEG signal classification and recognition effect is further improved. Meanwhile, the characteristic of light weight of the model meets the requirement of intelligent driving on real-time performance.
