Abstract The aim of this work is to explore the driving EEG in the traffic information based on the auditory perception by motor imagery. In the simulated whistle- brake environment, subjects control the vehicle by the left and right hand motor imagery, the feature was extracted and classified by CSP and linear regression algorithms and the recognition was 96.67%. Results: the signals sampled from C3 and C4 all showed that the voltage amplitude caused by the right hand imagery was higher, the difference between the maximum amplitude was 120 μV. Conclusion: compared to traditional perception of the visual task, the auditory one have advantages including (1) higher voltage amplitude can improve the signal extraction, and (2) the collection of EEG can optimize access to the traditional two-electrode acquisition mode by using the single one.
