Embodiment 1
[0044] In this example, if figure 2 As shown, vehicles 1, 2, 3, 4, 5, 6, 7, and 8 form a formation to drive, and there are dense trees or other obstacles on the roadside to block, vehicle 1 is the leading vehicle, and the rest are the rear vehicles. The formation vehicle communication in the prior art is that 1 vehicle sends to 2 vehicles, 2 vehicles send to 3 vehicles, and so on. When car 1 wants to send a message to car 8 directly, due to the influence of distance or interference, it cannot be done under normal circumstances, and it can only communicate through the above-mentioned relay mode, as shown by the dotted line 201 in the figure. In this embodiment, a V2X RSU is installed on the roadside, such as figure 2As shown in A and B, the coverage of RSU A is vehicles 1, 2, 3, and 4, and the coverage of RSU B is vehicles 5, 6, 7, and 8.
[0045] The vehicle formation communication system provided by the present invention can adopt the following steps:
[0046] Step S201,...
Embodiment 2
[0053] In this example, if image 3 As shown, vehicles 1, 2, and 3 in the formation are driving on a curve, vehicle 1 is the leading vehicle, and the rest are rear vehicles, and there are large trees or other obstacles on the roadside. In the prior art, if vehicle 1 wants to meet vehicle 2 at this time Or car 3 communicates, and at this time due to the influence of big trees or other obstacles, normal communication has been impossible. In this embodiment, a V2X RSU is installed on the roadside, such as image 3 As shown in C, the wireless network of RSU C can cover vehicles 1, 2, and 3
[0054] The vehicle formation communication system provided by the present invention can adopt the following steps:
[0055] Step S301, car 1 acquires lane information, such as fleet status, lane, speed, acceleration, braking, steering, etc., and sends the lane information through the OBU to the RSU C with the smallest distance using V2X wireless communication.
[0056] Step S302, RSU C broa...

Abstract
The invention discloses a vehicle formation communication system and method. The communication system comprises a head vehicle, at least one rear vehicle and at least one road side unit. The head vehicle acquires lane information; the lane information is sent to the road side unit with the smallest distance from the lane information through wireless communication; the roadside unit broadcasts thelane information to a rear vehicle and / or other roadside units within the coverage of a wireless network of the roadside unit; therefore, through information transfer of the at least one road side unit, the head vehicle and the at least one rear vehicle perform effective communication under the conditions of interference, more vehicles and the like, and the safety of vehicle formation driving is improved.
Description
technical field [0001] The invention relates to the technical field of vehicle communication, in particular to a vehicle formation communication system and method. Background technique [0002] The so-called formation driving refers to the automatic driving state in which two or more vehicles are connected by the Internet of Vehicles and automatic driving technology and followed by a very small distance between vehicles. The leading car acts as the leading car, and the following car (the following car) changes in real time according to the change of the leading car through the wireless network signal. The whole fleet is like a train connected by wireless signal. [0003] At present, vehicle formation communication generally uses wireless technologies, such as Dedicated Short Range Communications (DSRC) or Vehicle to Everything (V2X) technologies, to achieve communication between vehicles. Communication, but the frequency of DSRC or V2X communication is relatively high, and ...
