Roadside Internet of Vehicles Device, Viaduct Section Identification Method, and Vehicle Internet of Vehicles Device

Abstract

The present invention relates to the technical field of the Internet of Vehicles, in particular to a roadside Internet of Vehicles device, a method for identifying a viaduct road section, and a vehicle-mounted Internet of Vehicles device; the roadside Internet of Vehicles device includes a storage unit, a wireless transmission unit and a broadcasting unit for collecting and Broadcast the location point data of each viaduct section; the viaduct section identification method includes collecting the location data of the vehicle, and setting up the track record of the vehicle; receiving the broadcast of other Internet of Vehicles devices, when receiving the broadcast of the Roadside Internet of Vehicles device When the position point data set of multiple road sections is used, the evaluation index of the vehicle position and the multiple road sections is calculated according to the track record of the vehicle; and according to the calculated evaluation index, whether the vehicle enters or leaves a certain road section of the viaduct Identify and store. The on-vehicle Internet of Vehicles device includes a control unit loaded with a viaduct section identification program, and when the viaduct section identification program is executed, the above viaduct section identification method is executed.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, in particular to a roadside Internet of Vehicles device, a method for identifying a viaduct road section, and a vehicle Internet of Vehicles device. Background technique [0002] The Internet of Vehicles mainly refers to: the on-board equipment on the vehicle effectively utilizes all vehicle dynamic information in the information network platform through wireless communication technology, and provides different functional services during vehicle operation. The main features of the Internet of Vehicles are: the Internet of Vehicles can provide protection for the distance between vehicles and reduce the probability of vehicle collision accidents; the Internet of Vehicles can help car owners navigate in real time, and improve traffic through communication with other vehicles and network systems. operating efficiency. V2X (vehicle to everything, information exchange between vehicles...

AI Technical Summary

Problems solved by technology

[0003] Problems faced by V2X in the viaduct road section: Since the viaduct has multi-layer height plane sections, if we do not distinguish which level of the vehicle is driving on the road section, then there will inevitably be early warning errors caused by mutual influence of vehicles on different height plane sections. Report a problem

On the one hand, this solution requires additional hardware costs. If it is assumed that all vehicles equipped with V2X systems need to be equipped with this sensor, the total cost will be unbearable; on the other hand, the access of sensors will increase the complexity of the system. and instability, and increase system power consumption; in addition, the farthest warning range of V2X can reach several hundred meters, so different environmental factors (such as temperature) will also bring certain errors to the height sensor, and there is a risk of misjudgment
