Vehicle collision warning method, apparatus and device

Abstract

The invention relates to a vehicle collision warning method. The method comprises the steps of acquiring first state information of a current vehicle, second state information of an adjacent vehicle in a second preset distance of the current vehicle, and roadside information of an intersection when the current vehicle has a first preset distance from the intersection; determining a target vehiclewith a collision risk with the current vehicle on the basis of the first state information, the second state information and a preset screening condition; determining a first time period of the current vehicle running at the intersection on the basis of the first state information and the roadside information; acquiring a second time period of the target vehicle running at the intersection, wherein the second time period is generated by the target vehicle on the basis of the second state information and the roadside information acquired by the target vehicle; and when the first time period andthe second time period have an overlapped time point, performing explicit alarming of vehicle collision based on a running state of the current vehicle at a kth moment (k is greater than or equal to1) before current time. According to the method, the generation of false alarm in an ICW algorithm can be reduced.

Description

technical field [0001] The invention relates to a vehicle driving control method, in particular to a vehicle collision warning method, device and equipment. Background technique [0002] ICW (Intersection Collision Warning, intersection collision warning) function is an important function in the intelligent network driving system. It mainly controls the speed of vehicles approaching the intersection from different directions to ensure that each vehicle can alternately pass through the intersection to avoid collisions. risk. The key to the ICW algorithm is that the host vehicle finds a distant vehicle that may cause a collision risk through the intersection ahead, and reminds the host vehicle to slow down. With the development of V2X function, the form of V2V communication between vehicles makes it possible to realize the collision warning function in the non-line-of-sight range. After realizing the basic early warning function of ICW, preventing false alarm is also a very ...
