Embodiment Construction

[0035] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0036] refer to figure 1 , the vehicle anti-collision safety warning method of the first embodiment includes the following steps:

[0037] Step S11, obtaining the position information of the other car, and calculating the connection direction between the other car and the own car according to the position information of the other car and the position information of the own car;

[0038] Step S12, calculating the included angle between the speed direction of the own vehicle and the direction of the line connecting the two vehicles, and if the included angle falls within a preset angle range, it is determined that there is a possibility of collision.

[0039] In step S11, the location information of the other vehicle can be obtained through dedicated short-range communi...

Abstract

The invention provides a vehicle anti-collision safety warning method and device. The method includes the steps of obtaining position information of another vehicle, calculating the direction of the connecting line of one vehicle and another vehicle according to the position information of another vehicle and the position information of the vehicle, calculating the included angle between the speed direction of the vehicle and the connecting line of the vehicle and another vehicle, and judging that collision probability exists if the included angle is within the preset angle range. By means of the vehicle anti-collision safety warning method and device, a warning signal can be sent to a driver in time before accidents occur, and the traffic accident rate is decreased.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a vehicle anti-collision safety warning method and device. Background technique [0002] With the continuous increase of car ownership, the number of car accidents is also increasing year by year. In the prior art, passive technologies such as radar or video analysis are used to detect and judge dangerous situations such as vehicle collision and rear-end collision. [0003] Dedicated short-range communication (DSRC) can provide an information sharing channel between multiple vehicles, and can provide vehicle information (such as position, speed, braking status, etc.) to other surrounding vehicles through dedicated short-range communication. In the prior art, the application of dedicated short-range communication is often integrated in the integration of equipment, and there is no specific method for avoiding vehicle collisions by using dedicated short-range communicati...
