Problems solved by technology

[0004] However, the communication bandwidth of DSRC is small (generally 3Mbps), and it cannot transmit large amounts of data (such as audio and video data). Moreover, when DSRC has a problem, it will result in the inability to transmit vehicle driving information between vehicles in the autonomous driving fleet. , resulting in the inability of each vehicle to make accurate decisions and control based on the vehicle driving information of other vehicles in the autonomous driving fleet, and may even cause the vehicle to make wrong decisions and lead to serious safety accidents
Therefore, how to ensure the safety and reliability of the automatic driving of each vehicle in the autonomous driving fleet, the safe and reliable vehicle-to-vehicle communication technology is very important, and there is currently no reliable vehicle-to-vehicle communication technology

Embodiment 1

[0034] Such as figure 2 As shown, each vehicle in the automatic driving fleet is provided with an automatic driving fleet communication device (the following content of the application is represented by communication device 1), and each vehicle supports two communication technologies of DSRC and VLC. The respective communication devices 1 are used to transmit respective vehicle travel information and receive vehicle travel information of other vehicles between the vehicle and the vehicle.

[0035] see image 3 , is a schematic structural diagram of the communication device 1 in the embodiment of the present invention, the communication device 1 includes a communication control unit 11, a DSRC communication component 12 and a VLC communication component 13, wherein the communication control unit 11 communicates with the DSRC communication component 12 and the VLC communication component 13 respectively communication connection.

Embodiment 2

[0087]Based on the same idea as the communication device for the autonomous driving fleet provided in the first embodiment, the second embodiment of the present invention provides a communication method for the autonomous driving fleet, the method is applied to each vehicle in the autonomous driving fleet, and the autonomous driving fleet Each vehicle in is equipped with DSRC and VLC, the method Figure 6 shown, including:

[0088] Step 101 , monitor the availability status of the DSRC and VLC of the own vehicle.

[0089] Step 102 , when it is monitored that the DSRC is available, transmit vehicle driving information through the DSRC of the own vehicle.

[0090] Step 103 , when it is monitored that the DSRC is unavailable and the VLC is available, transmit the vehicle driving information through the VLC of the own vehicle.

[0091] In the embodiment of the present invention, there is no strict order of execution between step 102 and step 103, and step 102 may be executed fir...

Abstract

The invention discloses a self-driving fleet communication method and device, and solves the technical problems of poor reliability of vehicle-vehicle communication in the self-driving fleet in the prior art. According to the self-driving fleet communication method and device, a DSRC and a VLC are arranged on each vehicle of the self-driving fleet. The method comprises the steps that the availablestate of the DSRC and the VLC of the vehicle is monitored; when the DSRC is monitored to be available, vehicle driving information is transmitted through the DSRC of the vehicle; and when the DSRC ismonitored to be unavailable and the VLC is monitored to the available, the vehicle driving information is transmitted through the VLC of the vehicle. With application of the technical scheme, the reliability and the success rate of vehicle-vehicle communication in the self-driving fleet can be enhanced.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to an automatic driving fleet communication method and an automatic driving fleet communication device. Background technique [0002] With the development of autonomous driving technology and Internet of Vehicles technology, autonomous driving fleets become possible in application scenarios with relatively simple traffic environments (such as highways). All vehicles in the self-driving fleet have the ability to drive automatically, and the following vehicles can follow closely in sequence under the leadership of the leading vehicle. In order to ensure the safe driving of each unmanned vehicle in the autonomous driving fleet, it is very important for each unmanned vehicle to know the driving conditions of other vehicles in the fleet in a timely manner. [0003] Since DSRC (Dedicated Short Range Communications, dedicated short-range communication technology) is an efficient wireless ...
