Problems solved by technology

[0003] Currently, the Internet-connected communication system for platooning only relies on vehicle-mounted V2X terminals for communication, and can only transmit data such as accelerator, steering, map, and driving trajectory through simple transparent transmission, and has not formed a unified and commercialized system dedicated to platooning The complete Netlink communication system is only suitable for technicians to test and use, so it cannot be delivered to customers

Embodiment 1

[0099] Such as figure 1 As shown, this embodiment provides a network-connected communication system that realizes the vehicle platoon-following function, including the following functional modules.

[0100] Human-machine service module 1: obtain vehicle information, judge the desired service scheduling mode according to the vehicle information, and send the desired service scheduling mode command to the scheduling module 2;

[0101] Scheduling module 2: According to the desired service scheduling mode instruction, the message service module 4 is controlled to run in the corresponding service scheduling mode;

[0102] Vehicle information service module 3: Obtain the platoon-following information of the self-vehicle, and broadcast the platoon-following information of the self-vehicle to other vehicles in the fleet through the message service module 4; receive the platoon-following information of other vehicles in the fleet through the message service module 4 information, and s...

Embodiment 2

[0177] Such as Figure 5 As shown, on the basis of Embodiment 1, this embodiment provides a networked communication method for realizing the vehicle platoon-following function, including the following steps.

[0178] S1, obtain the real-time information of the vehicle;

[0179] S2, obtaining the communication range of the roadside unit;

[0180] S3, obtaining the expected information of the own vehicle;

[0181] S4, calculate the communication time interval according to the real-time information of the own vehicle, the communication range of the roadside unit and the expected information of the own vehicle;

[0182] S5, according to the obtained roadside unit communication range and the calculated communication time interval, judge whether the roadside unit communication range satisfies the full coverage of the expected driving trajectory;

[0183] S6. According to the judgment result, output the expected service dispatching mode instruction; specifically, if the roadside u...

Abstract

The invention discloses a networked communication system and method for realizing the vehicle platoon following function. The man-machine service module acquires vehicle information, judges the desired service dispatching mode according to the vehicle information, and sends the desired service dispatching mode command to the dispatching module; the dispatching module: According to the desired service scheduling mode command, the message service module is controlled to run in the corresponding service scheduling mode; the vehicle information service module: obtains the platoon-following information of the own vehicle, and broadcasts the platoon-following information of the own vehicle to other vehicles in the fleet through the message service module ;Receive the platoon-following information of other vehicles in the fleet through the message service module, and send the received platoon-following information of other vehicles in the fleet to the vehicle network; message service module: based on the corresponding service scheduling mode, complete Transparent transmission of platoon-following information between vehicles in the convoy. The invention satisfies the communication requirements of the platoon-following function of vehicles, is suitable for commercialization, scale management and matching, reduces communication calculation amount, and has flexible communication.

Description

technical field [0001] The invention relates to the field of vehicle platoon following, in particular to a networked communication system and method for realizing the vehicle platoon following function. Background technique [0002] Vehicle platoon following, as the most likely field of application of automatic driving rate, can effectively control the distance between vehicles and the driving state of the team, reduce the wind resistance during the driving of the team, reduce the fuel consumption of the vehicle, and will also greatly reduce the driver's Increased working intensity and improved driving safety. C-V2X networked communication technology is used as a communication medium between platooning and following vehicles, mainly including vehicle-to-vehicle communication technology (V2V), vehicle-to-infrared communication technology (V2I), etc. Vehicles share data resources through C-V2X networked communication, which can Effectively reduce the complexity of single-vehi...
