Abstract

The invention relates to a fatigue driving traffic guidance method based on V2X. The method comprises the steps of collecting and analyzing driving data of a current vehicle; judging whether the stateof the current vehicle is abnormal or not; and if so, processing the current vehicle according to the state of the current vehicle. And an RSU unit judges that the current vehicle runs abnormally according to the received current vehicle running data, and broadcasts a message to the current vehicle. And the current vehicle receives the broadcast message and judges that the driver is in fatigue driving by combining the judgment of the face and action of the driver of the high-definition camera, and the current vehicle can send out a fatigue driving warning to a navigation system of the currentvehicle to make a voice broadcast alarm. The piece of warning is also broadcast to surrounding vehicles and RSU unit. And the RSU unit carries out traffic dispersion after receiving the fatigue driving alarm, and guides the current vehicle to enter a nearby safe place for rest. Harm possibly caused by fatigue driving is avoided from the aspects of judgment and traffic dispersion, and the dangerous situation possibly caused by fatigue driving is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle communication, in particular to a V2X-based fatigue driving traffic guidance method. Background technique [0002] At present, in the investigation of the cause of traffic accidents in recent years, it has been found that in the traffic accidents caused by human factors, the proportion of traffic accidents caused by fatigue driving accounts for a large part. It can be seen that fatigue driving is an important cause of traffic accidents. Researching the characteristics of fatigue driving behavior and predicting and warning are important methods to solve fatigue driving. [0003] Existing research on driving fatigue behavior is mainly identified through the extraction of physiological features. For example, extracting the driver's physiological indicators, facial feature recognition and other methods. It is difficult to extract the physiological characteristics of the driver by non-contact acquisi...
