The invention relates to a monitoring method for cognitive distraction of a driver on the basis of multi-source information fusion, and belongs to the technical field of automotive active safety.The method comprises the steps that the steering wheel angle, the vehicle speed and the head orientation and fixation point position coordinate information of the driver are collected in real time; data collected in real time is arranged into a data sequence according to the time order; according to a time-domain statistical indicator set (cognitive distraction characteristic set) of the steering wheel angle, the vehicle speed and the head orientation and fixation point position coordinate information of the driver is calculated within the computing time window length range, and real-time monitoring is conducted on the cognitive distraction state of the driver by adopting feature-level multi-source information fusion based on a support vector machine.Therefore, the purposes of improving the driving safety and reducing road traffic accidents are achieved.
