[0026] The present invention will be further described below in conjunction with the accompanying drawings.
[0027] The invention adopts the azimuth measurement method combined with the virtual road fitting technology to eliminate false alarms. The defined azimuth is the angle between the line formed by the two vehicles and the line formed directly in front of the vehicle, as shown in the attached figure 1 As shown, the vehicle 1 and the vehicle in front 2 are driving on the curve 3. According to their speed and distance, if they follow the straight lane judgment rules, they will issue a collision warning or take active anti-collision measures; but because they are in the curve 3 In the different lanes on the road, no collision is expected, so it is a "false alarm". In order to remove this false alarm, it is necessary to judge whether the two vehicles are in the same lane. If they are in the same lane, it is not a false alarm. If they are in different lanes, they are false a...
