Integrated warning device for drivers based on vehicle-road coordination

Abstract

The invention relates to an integrated driver early warning device based on vehicle-road cooperation, which comprises a vehicle state sensing module, an external environment sensing module, a master control module, a vehicular wireless communication module and a human-computer interaction module. Output signals of the vehicle state sensing module and the external environment sensing module are inputted into the master control module which is communicated with surrounding vehicles and equipment on the road through the wireless communication module, and the master control module sends out early warnings through the human-computer interaction module. The integrated driver early warning device is capable of acquiring driving intentions of surrounding vehicles by means of vehicle-vehicle communication, thereby recognizing and sending out early warnings of potential dangers. Meanwhile, vehicle-vehicle or vehicle-road communication can be realized, information about the vehicle can be sent to the surrounding vehicles and the roadside facilities, and auxiliary driving safety can be achieved through the vehicle-road cooperation.

Description

technical field [0001] The invention relates to the field of road traffic safety research, in particular to a comprehensive monitoring and early warning device for driving behavior, and belongs to the field of automobile safety auxiliary driving. Background technique [0002] Studies have shown that in the "human-vehicle-road" road traffic system, human factors are the main cause of road traffic accidents. The driver's erroneous understanding of the external environment and wrong operations during driving will seriously affect the driving safety of motor vehicles. Therefore, the development of key vehicle-mounted auxiliary driving devices to increase the interaction between the driver and the surrounding environment (especially the interaction between the driver's dangerous driving state and driving intention), and to strengthen the monitoring of driving behavior can effectively ensure driving safety. At present, some safety-assisted driving devices have been announced at h...

AI Technical Summary

Problems solved by technology

[0004] Currently, most of the vehicle safety auxiliary driving devices disclosed are based on the collection of the vehicle state and the external environment state by the vehicle sensor. The lack of information exchange based on vehicle-to-vehicle / vehicle-road communication, especially the lack of interaction of important information such as driver status and driving intentions, makes it difficult to achieve true vehicle-road coordination and safe assisted driving.
