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

[0047] Such as image 3 Shown here is a schematic structural diagram of the first communication device 1 in the embodiment of the present invention. The first communication device 1 is set in the main control car of the autopilot fleet. The first communication device 1 includes a communication control unit 11 and a DSRC communication component 12 With the VLC communication component 13, the communication control unit 11 is respectively connected to the DSRC communication component 12 and the VLC communication component 13, wherein:

[0048] The communication control unit 11 is used to monitor the available status of DSRC and VLC of all vehicles in the autonomous driving fleet; if the DSRC of all vehicles is monitored to be available, then: control the DSRC communication component 12 to transmit vehicle driving information, and control all slaves The vehicle transmits vehicle driving information through its own DSRC; if it is monitored that the DSRC of some or all vehicles is unava...

Embodiment 2

[0091] Such as Figure 5 Shown is a schematic structural diagram of the second communication device 2 in the embodiment of the present invention. The second communication device 2 is set in the slave-controlled car of the autonomous driving fleet. The second communication device 2 includes a communication control unit 21 and a DSRC communication component 22. With the VLC communication component 23, the communication control unit 21 is respectively connected to the DSRC communication component 22 and the VLC communication component 23, wherein:

[0092] The communication control unit 21, upon receiving the first control instruction for instructing the use of DSRC to transmit vehicle travel information, controls the DSRC communication component 22 to transmit the vehicle travel information; and, upon receiving the control instruction for using VLC to transmit vehicle travel information When instructed, the VLC communication component 23 is controlled to transmit vehicle driving inf...

Embodiment 3

[0122] See Figure 7 , Is the communication system of the autonomous driving fleet in the embodiment of the present invention. The communication system includes a first communication device 1 arranged in the master vehicle of the autonomous driving fleet and a second communication device arranged in the slave vehicle of the autonomous driving fleet 2. The structure of the first communication device 1 can refer to the content of the first embodiment, and the structure of the second communication device 2 can refer to the content of the second embodiment, which will not be repeated here.

Abstract

The invention discloses a communication method, device and system of an auto-piloted fleet, so as to solve the technical problem that in the prior art, the reliability of vehicle-vehicle communications in the auto-piloted fleet is poor. A DSRC (dedicated short range communications) and VLC (visible light communications) are arranged on each vehicle in the auto-piloted fleet. The communication method comprises the following steps of monitoring the available conditions of the DSRC and the VLC of all the vehicles in the auto-piloted fleet by a master control vehicle; if the situation that the DSRC of all the vehicles are available is monitored, controlling all the vehicles to transmit vehicle travelling information through the corresponding own DSRC; and if the situation that the DSRC of a part of the vehicles or all the vehicles are not available and the VLC of all the vehicles are available is monitored, controlling all the vehicles to transmit the vehicle travelling information throughthe corresponding own VLC. Through the adoption of the technical scheme of the communication method disclosed by the invention, the reliability and the success rate of the vehicle-vehicle communications in the auto-piloted fleet can be improved.

Description

Technical field [0001] The invention relates to the field of automatic driving, in particular to an automatic driving fleet communication method, an automatic driving fleet communication device, and an automatic driving fleet communication system. Background technique [0002] With the development of autonomous driving technology and Internet of Vehicles technology, in relatively simple application scenarios (such as highways) in the traffic environment, autonomous driving fleets become possible. All vehicles in the self-driving fleet have automatic driving capabilities, and under the leadership of the leader, the following vehicles can follow closely in turn. In order to ensure the safe driving of the unmanned vehicles in the autonomous driving fleet, it is very important for the unmanned vehicles to learn the driving conditions of other vehicles in the fleet in time. [0003] Because DSRC (Dedicated Short Range Communications, dedicated short-range communication technology) is a...
