Embodiment 1

[0053] In this embodiment, the driver's driving pattern analysis system is used to obtain the EEG signal data of the driver under different working conditions, so as to analyze the driving characteristics of the driver.

[0054] Through the scenario simulation module in the driving environment simulation module, a simulated driving scene with natural traffic flow is set up, and there are four kinds of simulated driving conditions set up, which are respectively: car following, overtaking, curve and free driving ( straight). Under these four working conditions, the driver makes corresponding driving behaviors and driving reactions according to different working conditions.

[0055] The EEG signal collection module collects the driver's EEG signal under different working conditions, and transmits the collected driver's EEG signal to the EEG signal analysis module, and the EEG signal analysis module receives the driver's EEG signal. The electrical signal is processed to the drive...

Embodiment 2

[0062] In this embodiment, the driving characteristics of the driver are analyzed for the three driving patterns of the driver through the aforementioned driver driving pattern analysis system. The three driving modes are: normal mode, relaxed mode and tense mode. Such as Figure 4 As shown, the specific analysis process is as follows:

[0063] Step 1: Simultaneously collect the driver's EEG signal, EMG signal and facial image information;

[0064] Specifically, through the signal acquisition and analysis module, the EEG signal acquisition module collects the F3 / F4 channel and O1 / O2 channel data in the international 10-10 EEG standard electrode position system diagram corresponding to the driver's brain, specifically refer to For details, see:
