Various internets of vehicles integrated vehicular system

Abstract

The invention provides a various internets of vehicles integrated vehicular system. The system is characterized by comprising a DSRC communication module, an LTE-V communication module, a data processing module and a positioning module. The DSRC communication module is used for carrying out vehicle-to-vehicle communication and receiving driving information and traffic management information of a current vehicle and surrounding vehicles. The LTE-V communication module is used for carrying out vehicle-to-road communication, receiving the driving information of the current vehicle and receiving the traffic management information of road-side units. The data processing module is used for calculating the driving information and the traffic management information received by the DSRC communication module and the LTE-V communication module. The positioning module is used for positioning the vehicle in a double-mode positioning mode. According to the system, through integration of DSRC and LTE-V Internets of vehicles, learning from each other is carried out, and advantages of the two technologies are utilized fully; the vehicle-to-vehicle communication is established based on the DSRC; the vehicle-to-road communication is established based on the LTE-V; under the condition of saving investment, the Internet of vehicles is established; the road safety level is improved; and the trip experience is improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a vehicle-mounted system integrating multiple vehicle networking. Background technique [0002] DSRC (Dedicated Short Range Communications, dedicated short-range communication technology) and LTE-V (LTE-Vehicle, car-linked network based on LTE technology) are the two potential technology systems for the Internet of Vehicles in the future. DSRC is led by European and American countries, and LTE-V is led by European and American countries. Our country dominates. The advantage of DSRC lies in vehicle-to-vehicle communication, which has the advantages of network self-organization and small end-to-end delay. However, building a network of vehicles based on DSRC for vehicle-to-road communication requires a large number of roadside equipment to be deployed and huge investment. If roadside equipment cannot Achieving coverage will cause intermittent vehicle-to-road communic...

AI Technical Summary

Problems solved by technology

The advantage of DSRC lies in vehicle-to-vehicle communication, which has the advantages of network self-organization and small end-to-end delay. However, building the Internet of Vehicles based on DSRC for vehicle-road communication requires the deployment of a large number of roadside equipment and huge investment. If the roadside equipment cannot The realization of coverage will lead to intermittent vehicle-road communication, which will affect the use effect

The advantage of LTE-V lies in its extensive base station coverage, and it can effectively realize vehicle-road communication without a large amount of repeated investment. However, the end-to-end time delay of vehicle-vehicle communication based on LTE-V is large, which will improve road safety. Limited, and the wireless resources of vehicle-mounted terminals need to be allocated and dispatched by the base station. If the vehicle is driving in an area without base station coverage, vehicle-to-vehicle communication will not be possible
