The invention provides an extra-long highway tunnel driving state evaluation method based on man-vehicle cooperation information. Comprising the following steps: constructing a human and vehicle information index system for evaluating the driving state of the extra-long highway tunnel; the method comprises the steps of collecting extra-long highway tunnel driving state evaluation index data, and performing preprocessing; extracting characteristic quantities reflecting state abnormity in the physiological information of the driver and the vehicle driving information by using a Hilbert-Huang algorithm; constructing a Bayesian network structure based on human and vehicle state information; and performing parameter learning of the network by using a similarity aggregation method, and verifying the Bayesian network model by selecting a comparison test method. According to the invention, fine processing of non-stationary physiological signals and vehicle driving signals in a complex scene is realized, and abnormal information in the signals is extracted; and the driving state is subjected to real-time judgment and probability updating by fully utilizing the prior information of the driver and the vehicle operation. The driving state in the extra-long highway tunnel environment can be evaluated, and the probability of traffic accidents in the tunnel is reduced.
