A kind of front collision control method, front collision warning device and automobile

Abstract

A front collision warning method is used to analyze the collision danger between a vehicle and a distant vehicle and send an early warning, the method includes: receiving vehicle information sent by the distant vehicle and road information sent by a roadside unit; information, identify the far car in the same lane and the adjacent lane closest to the vehicle; perform vector calculation on the far vehicle to obtain the shortest distance between the own vehicle and the far vehicle; When the distance is less than the warning distance threshold and the far vehicle is in the same lane as the own vehicle, an early warning is sent. The invention also provides a front collision early warning device and an automobile for realizing the front collision early warning method. Based on the road information and surrounding vehicle information sent by the roadside unit, the present invention can monitor the far vehicles in the same lane and adjacent lanes as the vehicle in real time for any road, and based on the calculation method of the vector method, it can be used on straight roads and any curves. It is applicable to both, and can accurately and timely warn the driver of the danger of a forward collision.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a front collision control method, a front collision warning device and an automobile. Background technique [0002] Forward collision warning is of great significance to driver safety. At present, there are many studies on forward collision warning on straight roads. The limitations of the recognition of target vehicles on curves, such as heavy fog and snow, cause the vehicle to be damaged on curves. The forward collision warning is inaccurate. [0003] The traditional forward collision warning mainly relies on radar and camera to identify the target vehicle. In the case of bad weather, it is easy to cause the loss of the target vehicle, or when driving on a curved road, for the identification of the forward collision warning target, HV just When entering a curve, it may be recognized that the vehicle in the adjacent lane has a collision threat, but the vehicle in this lane is ...

[0003] The traditional forward collision warning mainly relies on radar and camera to identify the target vehicle. In the case of bad weather, it is easy to cause the loss of the target vehicle, or when driving on a curved road, for the identification of the forward collision warning target, HV just When entering a curve, it may be recognized that the vehicle in the adjacent lane has a collision threat, but the vehicle in this lane is not recognized; or on roads such as continuous curves, due to the occlusion of surrounding objects, the distant vehicle cannot be recognized, resulting in the identification of the vehicle ahead. If not, the front collision warning will be missed or falsely reported, which is not conducive to the driving safety of the vehicle. At the same time, the frequent sending of warning messages is not considered, resulting in a poor experience of the warning function.
