Embodiment 1

[0029] Such as figure 1 As shown, the embodiment of the present invention provides a vehicle collision avoidance method, the method comprising:

[0030] Step 101: Obtain the instant point coordinates of the accident vehicle and the instant point coordinates of the currently driving vehicle.

[0031] Specifically, the instant point coordinates of the accident vehicle are sent by the high-speed broadcast center to the traveling vehicles in the space covered by the broadcast through multicast mode, and the instant point coordinates of the accident vehicle are, when the collision on the accident vehicle When the detection device detects a collision, the accident vehicle actively sends it to the high-speed broadcast center.

[0032] Further, when the collision detection device on the accident vehicle detects that a collision has occurred, the accident vehicle actively sends the accident information and the GPS instant point coordinates of the accident vehicle to the high-speed bro...

Embodiment 2

[0044] Such as figure 2 As shown, the present embodiment provides a vehicle collision avoidance method, the method comprising:

[0045] Step 201: Obtain the instant point coordinates of the accident vehicle and the instant point coordinates of the currently driving vehicle.

[0046] Specifically, the instant point coordinates of the accident vehicle are sent by the high-speed broadcast center to the traveling vehicles in the space covered by the broadcast through multicast mode, and the instant point coordinates of the accident vehicle are, when the collision on the accident vehicle When the detection device detects a collision, the accident vehicle actively sends it to the high-speed broadcast center.

[0047] Furthermore, when the collision detection device on the accident vehicle detects that a collision has occurred, the accident vehicle actively sends the accident information and the GPS instant point coordinates of the accident vehicle to the high-speed broadcast cente...

Embodiment 3

[0091] As shown in Figure 3, an embodiment of the present invention provides a vehicle collision avoidance method, the method comprising:

[0092] Step 301: Acquiring the instant point coordinates of the accident vehicle, the instant point coordinates and the previous point coordinates of the currently driving vehicle.

[0093] Specifically, the instant point coordinates of the accident vehicle are sent by the high-speed broadcast center to the traveling vehicles in the space covered by the broadcast through multicast mode, and the instant point coordinates of the accident vehicle are, when the collision on the accident vehicle When the detection device detects a collision, the accident vehicle actively sends it to the high-speed broadcast center.

[0094] Furthermore, when the collision detection device on the accident vehicle detects that a collision has occurred, the accident vehicle actively sends the accident information and the GPS instant point coordinates of the accide...

Abstract

The invention discloses a vehicle anti-collision method and device, belonging to the technical field of communication. The method comprises the steps of acquiring the instant point location coordinate of a vehicle which has an accident and the instant point location coordinate of a vehicle which runs at present; determining the relative position information of the vehicle which has the accident and the vehicle which runs at present according to the instant point location coordinate of the vehicle which has the accident and the instant point location coordinate of the vehicle which runs at present; and judging whether the vehicle which runs at present has a risk of accident or not according to the relative position information. The device comprises an acquisition module, a determination module and a judgment module. Since whether the vehicle which runs at present has the risk of accident or not is judged according to the relative position information of the vehicle which has the accident and the vehicle which runs at present in the embodiment disclosed by the invention, the vehicle which runs at present can make a response to the accident which happens at the front in advance according to the judgment result and chain-reaction tailgating accidents can be effectively reduced or even avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle anti-collision, in particular to a vehicle anti-collision method and device. Background technique [0002] On highways or areas with fewer pedestrians, cars usually travel faster, and accidents such as collisions often occur. After a collision accident with the vehicle in front, the vehicle behind usually can only know the accident at a position close to the accident point, and at the same time, it is in a high-speed driving state, so it is difficult to respond quickly to the accident, which will lead to serial rear-end collisions The occurrence of the incident caused serious casualties and economic losses. [0003] There is an anti-collision method in the prior art. In this method, a vehicle and its surrounding vehicles form a temporary mobile ad hoc network, and the vehicle safety-related information such as its own acceleration, speed, and position are transmitted to each other. Based on these...
