Embodiment 1

[0033] see figure 1 , is a flow chart of an embodiment of a road intersection collision avoidance warning method based on the vehicle-road coordination technology of the present invention. Specifically, the road intersection collision avoidance warning method in this embodiment includes steps:

[0034] S1, the roadside device receives the GPS information sent by each vehicle on each section of road at the intersection through the vehicle-mounted device. In this embodiment, a specific roadside device and a specific vehicle-mounted device are used to realize data interaction between the two. Specifically, the roadside device mainly includes a connected communication module and a data processing module, wherein the communication module specifically A short-range communication (Dedicated Short Range Communication, DSRC) module can be used, and the data processing module can use a computing unit integrated with an anti-collision warning algorithm, such as a single-chip microcomput...

Embodiment 2

[0059] Based on the above-mentioned anti-collision warning method at an intersection, the present invention also provides a roadside device. The roadside device of the present invention will be described in detail below in conjunction with specific embodiments.

[0060] see Figure 7 , is a functional block diagram of an embodiment of a roadside device of the present invention. Specifically, the roadside equipment in this embodiment includes a communication module 11, and a data processing module 12 connected to the communication module 11, wherein,

[0061] The communication module 11 is used to receive GPS information sent by all vehicles in its coverage area through the vehicle-mounted device, and feed back the early warning information generated by the data processing module 12 to the vehicle-mounted device of the corresponding vehicle; in a specific embodiment, the The communication module adopts the DSRC communication module, and its coverage is each road section within...

Embodiment 3

[0068] Correspondingly, the present invention also provides a road intersection collision avoidance warning system based on vehicle-road coordination technology, which will be described in detail below with reference to specific embodiments and accompanying drawings.

[0069] see Figure 8 , is a functional block diagram of an embodiment of a road intersection collision avoidance warning system based on vehicle-road coordination technology of the present invention. Specifically, the road intersection collision avoidance warning system in this embodiment includes the roadside equipment installed at the intersection in the second embodiment above, and the vehicle-mounted equipment installed on each vehicle. The on-board equipment of the vehicle within the communication range of the side equipment is connected through DSRC wireless communication, wherein,

[0070] The vehicle-mounted device is used to collect the GPS information of the vehicle itself, and send it to the above-ment...

Abstract

The invention discloses a road intersection anti-collision early warning method, road-side equipment and an anti-collision system based on vehicle infrastructure integration technology. According to the road intersection anti-collision early warning method, GPS information which is transmitted by each vehicle through specific on-vehicle equipment is received by the road-side equipment arranged at a road intersection, and furthermore collision predication analysis is performed on the data of the GPS information, thereby generating early-warning information. Furthermore the early-warning information is forwarded to the vehicles with potential collision risks. Finally after the on-vehicle equipment receives the early-warning information, the on-vehicle responds to the early-warning information, thereby reducing collision probability between vehicles in the ramp and the main road of the intersection, and furthermore greatly improving vehicle driving safety on condition of high-speed driving or blind area at the intersection.

Description

technical field [0001] The invention relates to the fields of intelligent transportation, intelligent vehicles and Internet of Vehicles, in particular to a road intersection collision avoidance warning method based on vehicle-road coordination technology, roadside equipment and a collision avoidance system. Background technique [0002] With the in-depth development of urbanization, transportation is facing severe challenges. In order to alleviate the current traffic problems, the Internet of Vehicles (IoV) technology came into being. It aims to realize the interconnection between vehicles, roadside equipment and other vehicles through V2X, so as to finally achieve the purpose of cooperative driving. Foreign research is relatively early, mainly including the European Cooperative Vehicle Infrastructure System (CVIS), the IntelliDrive research program organized by the US Department of Transportation, and the similar Car-TAK2000 program. Domestic research is relatively late, b...
