Problems solved by technology

However, the traditional forward collision warning system is very safe for vehicles traveling on straight roads, but it is powerless for vehicles traveling on curves
Especially at curves, due to obstacles such as buildings or mountains, the driver cannot observe whether there is a vehicle coming from the opposite side, and it is easy to cause a vehicle collision due to lane departure

Embodiment Construction

[0050] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0051] A collaborative collision avoidance warning method for curves based on dedicated short-range communication, such as figure 1 As shown, the targeted scene is a curve, and there is an obstruction (such as a tall building or a mountain) at the curve, which causes the driver to have poor vision. Specifically, it is achieved through the following steps, as figure 2 Shown:

[0052] Step 1: Identify the position of the ego vehicle;

[0053] Receive the location information of the own vehicle in real time, including the latitude and longitude data of the vehicle and the driving direction of the vehicle; combine the location information of the own vehicle with the position information (longitude and latitude) of the entrance of each curved road section on the electronic map (the entrance of the curved road section is determined by the driving direction of the vehicle...

Abstract

The invention discloses a method for curve synergy collision avoidance early warning based on dedicated short range communication. The method specifically comprises the steps that real-time position information of an automobile of a user is obtained and whether the automobile enters a curve zone or not is judged with the combination of an electronic map; if the automobile enters a curve, traveling information of the automobile of the user is broadcasted to the surroundings and whether an automobile traveling oppositely exists or not is inquired through a dedicated short range communication device; if the automobile traveling oppositely exists, traveling information and position information of the automobile traveling oppositely are obtained and combined with the traveling information and the position information of the automobile of the user, the smallest lateral distance and time needed when the two automobiles meet are predicated, and the smallest lateral distance and the time needed when the two automobiles meet are compared with a set threshold value so that collision avoidance early warning in levels can be achieved. The method for curve synergy collision avoidance early warning based on dedicated short range communication has the advantages that the smallest lateral distance and the time needed when the two automobiles meet can be predicated, interaction of the automobile conditions and the early warning information is achieved through dedicated short range communication, and therefore the purpose of curve synergy collision avoidance early warning is achieved.

Description

technical field [0001] The invention relates to the technical field of dedicated short-range communication, in particular to a collaborative collision avoidance warning method for curves based on dedicated short-range communication. Background technique [0002] Curves are road sections where traffic accidents occur frequently, and the probability of accidents is high and the severity of accidents is high. On a road with a unit mileage, the number of accidents on curves is significantly higher than that on straight roads. This is because vehicles are prone to lane departure, vehicle collisions, or sideslips or even rollovers due to excessive speed when driving on curved roads. Waiting for danger. The frequent occurrence of accidents on curved road sections seriously restricts the improvement of the overall safety level of the highway. Statistics show that most of the traffic accidents on road curves are caused by the deviation of driving behavior. If the danger can be dete...
