Embodiment Construction

[0040] Below in conjunction with accompanying drawing, the present invention will be further described:

[0041] like figure 1 As shown, the present invention relies on the DSRC protocol 2 The BSM message (Basic Security Message) defined in , and the processing and use of the message. In the calculation process of the entire collision warning, the BSM message is the carrier of vehicle information. When the vehicle receives the BSM message of other vehicles, it should analyze the message and combine the corresponding information of the vehicle to determine whether there is a risk of collision. exist.

[0042] The whole process of anti-collision warning calculation is as follows: figure 1 shown.

[0043] According to the above, the functional realization of the present invention includes the following seven aspects:

[0044] 1) Establish the latitude and longitude coordinate system of the vehicle: the latitude and longitude coordinate system of the vehicle takes the positio...

Abstract

The invention provides an anti-collision early warning method based on a DSRC vehicle-to-vehicle communication technology. The anti-collision early warning method based on a DSRC vehicle-to-vehicle communication technology can calculate whether a risk of collision between two vehicles exists according to the position and the speed information of a personal vehicle, and the position and the speed information of other vehicles. For the anti-collision early warning method, vehicle communication is performed based on DSRC; each one of mutually communicating two vehicles carries a vehicle device; and the vehicle device sends the position and speed information of the personal vehicle and receives the position and speed information of other vehicles in the communication range. The anti-collision early warning method relies on the BSM (Base Safety Message) in a DSRC communication protocol, and is high in standardability; after promotion of the DSRC, the anti-collision early warning method can be applied widely and is suitable for a vehicle networking system for the future DSRC communication.

Description

technical field [0001] The invention belongs to the technical field of collision research between vehicles on traffic roads, and specifically relates to an anti-collision warning algorithm based on DSRC (dedicated short-range communication technology) vehicle-to-vehicle communication technology, which is calculated according to the position and speed information of the own vehicle and the position and speed information of other vehicles. Whether there is a risk of collision between the two vehicles. Background technique [0002] The rapid development of modern science and technology has made the transportation network complicated. Under the high-speed economic development model, the growth rate of vehicles has been far higher than the construction speed of roads and other transportation facilities, especially the growth of private car ownership. posed no small challenge. While private cars bring people faster efficiency and a more comfortable driving environment, they also ...
