Anti-collision early warning method based on DSRC vehicle-to-vehicle communication technology

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 ...

However, the disadvantage of this method is that the amount of data processing is large, there will be high requirements for hardware, and it is also limited by the influence of road environment, road surface environment, climate conditions, and light conditions.

[0005] Range-based vehicle collision avoidance technology has good accuracy on straight roads, but is not suitable for curves or intersections
