performing, by a driver, at least one responsiveness test item before staffing a vehicle, wherein the at least one responsiveness test item includes one or more of playing a section of a video image for simulating driving or playing a section of a voice prompt with driving instructions for the driver;

applying a brain-computer interface to acquire an electroencephalogram signal of the driver performing the at least one responsiveness test item, and analyzing the electroencephalogram signal to generate feedback information, the feedback information comprises intentions actually generated by the driver when performing the responsiveness test item and starting time of generating the intentions;

based on a preset test standard that comprises correct intentions supposed to be generated by the driver when performing the responsiveness test item and a time threshold of generating the correct intentions, wherein when one responsiveness test item is provided, if the starting time exceeds the time threshold or the intentions generated within the time threshold are not equal to the correct intentions, it is determined that the driver has the risky driving behavior;

when a plurality of responsiveness test items are provided, if the amount of the starting time exceeding the corresponding time threshold is greater than a preset amount or the number of the intentions generated within the time threshold and not equal to the corresponding correct intentions is greater than a preset number, it is determined that the driver has the risky driving behavior; and

further comprising a vehicle starting unlocking module, wherein the vehicle starting unlocking module is electrically connected with the processor module and a vehicle ignition system respectively, and when the processor module determines that the driver has the risky driving behavior, the processor module controls the vehicle starting unlocking module to shut down the vehicle ignition system.
