Embodiment

[0032] This embodiment provides a vehicle-to-vehicle coordination system based on V2X, such as figure 1 As shown, it includes a data processing module and a data acquisition module respectively connected to the data processing module, a cloud data acquisition module, a vehicle body control module, and a human-computer interaction HMI module, wherein:

[0033] 1.1 Data acquisition module

[0034] Because the present invention is directly aimed at actual usage, so the data acquisition module is divided into four aspects:

[0035] The first is remote vehicle data acquisition. This part is completed by a third party integrating the V2X protocol stack and the Internet of Vehicles hardware that meets IEEE802.11p or DSRC. Here, Cohda MK5 is used, and it can be received by parsing such equipment according to the established format. To the basic data of the remote car body, of course, the body data of this car can also be sent out by radio frequency through such equipment;

example 1

[0116] Scenario description: The convoy is driving on a road with three lanes on the planned route and encounters road construction ahead. The RSU broadcasts this situation. The on-board OBU detects the RSU broadcast message, and the convoy becomes a single-lane situation on a road section. image 3 as shown,

[0117] 1. The initial state is that all vehicles in the convoy travel at a constant speed of v1 according to the position in the picture;.

[0118] RV1 detects itself as the pilot vehicle and keeps driving in V1 without changing lanes;

[0119] 2. HV and RV2 detect that there is a situation ahead and must merge into the middle lane. In the scene where two vehicles entering the spaced lane merge into the same lane, HV decelerates to v2 to change lanes in advance, and RV2 decelerates with a greater deceleration v3, which affects subsequent follow-up Vehicles such as RV3, RV3 starts to follow RV2 with speed v4;

[0120] 3. After the HV successfully changes lanes, it aims...

example 2

[0124] Scenario description: The fleet is driving on a road with three lanes on the planned route. The control decision-making module will judge the positional relationship between the vehicle and the surrounding vehicles, and maximize the use of each lane through the "principle of high efficiency". The optimized As a result, the fleet that was originally about 5 times the length of the standard vehicle spacing was reduced to about 3.5 times the length of the vehicle standard spacing. If the length of the fleet is larger and the arrangement is more irregular, the benefits of optimization will be more obvious, which will greatly improve urban roads. and highway traffic efficiency, such as Figure 4 shown.

Abstract

The invention discloses a vehicle-vehicle cooperative system based on V2X. The vehicle-vehicle cooperative system based on V2X comprises a data processing module, a data acquisition module connected,a cloud data acquisition module, a vehicle body control module and a man-machine interaction module, wherein the data acquisition module, the cloud data acquisition module, the vehicle body control module and the man-machine interaction module are connected with the data processing module. The data acquisition module is used for acquiring far vehicle data, vehicle body CAN data, GPS data and inertial navigation system data. The data processing module includes a high precision map module and a decision control module, and the decision control module is used for generating messages in the specified format according to a protocol, processing the data acquired by the data acquisition module and the high precision map module, performing collaborative driving planning, sending driving instructions to the vehicle body control module, sending alarming and guidance to the man-machine interaction module, and seconding data to the cloud data acquisition module. According to the technical scheme,the complex information interaction between vehicles when the vehicles coordinate with each other is solved, the vehicle traffic efficiency of cities and highways is improved, and safe driving is balanced.

Description

technical field [0001] The present invention relates to the field of intelligent transportation, in particular to a V2X-based vehicle-vehicle coordination system and method. Background technique [0002] In recent years, my country's automobile industry has developed rapidly, and the number of vehicles in cities is increasing. According to the statistics of the National Bureau of Statistics, as of the end of 2016, the number of civilian vehicles in my country was 194.4 million. The rapid development has brought convenience to people and also The problem of urban traffic congestion has been aggravated. People spend more than twice as much time traveling by vehicle during peak traffic periods than at other times. Urban traffic pressure urgently needs to be alleviated; [0003] The patent "Vehicle-Vehicle Cooperative Control System at Unsignalized Intersection Based on Fish Swarm Effect" with the application number "201510054091.1" introduces the composition of the cooperative s...
