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 As shown, it 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 master vehicle of the automatic driving fleet. The first communication device 1 includes a communication control unit 11 and a DSRC communication component 12 With VLC communication assembly 13, communication control unit 11 is connected with DSRC communication assembly 12 and VLC communication assembly 13 respectively, wherein:

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

Embodiment 2

[0091] Such as Figure 5 As shown, it 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 control vehicle of the automatic driving fleet, and the second communication device 2 includes a communication control unit 21 and a DSRC communication component 22 With VLC communication assembly 23, communication control unit 21 is connected with DSRC communication assembly 22 and VLC communication assembly 23 respectively, wherein:

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

Embodiment 3

[0122] see Figure 7 , is the communication system of the automatic driving team in the embodiment of the present invention, the communication system includes the first communication device 1 set in the master control car of the automatic driving team and the second communication device 1 set in the slave control car of the automatic driving team 2. For the structure of the first communication device 1, refer to the content of Embodiment 1, and for the structure of the second communication device 2, refer to the content of Embodiment 2, 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, 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 c...
