Abstract

The invention belongs to the technical field of vehicle pre-warning and discloses a lane-changing auxiliary pre-warning method, a lane-changing auxiliary pre-warning device, lane-changing auxiliary pre-warning equipment and a storage medium. The lane-changing auxiliary pre-warning method comprises the following steps of receiving a user pre-warning prompt command opening command to acquire first vehicle information of a main vehicle and second vehicle information of a target vehicle in a vehicle preset area; calculating a vehicle distance according to the first vehicle information and the second vehicle information; and comparing the vehicle distance with a preset initial distance threshold value to acquire a distance comparison result and a time comparison result, and determining the pre-warning prompt through which the main vehicle executes a lane-changing operation according to the distance comparison result and the time comparison result. In this way, two pre-warning policies: a distance pre-warning policy and a time pre-warning policy are combined, so that the pre-warning accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of vehicle early warning, in particular to a lane change auxiliary early warning method, device, equipment and storage medium. Background technique [0002] With the development of intelligent driving technology, the early warning function brings users a safer driving experience in terms of driving assistance. The lane change auxiliary warning detects the vehicle status and position information of the adjacent lane of the vehicle through the angular millimeter-wave radar, and judges whether the vehicle can change lanes by analyzing and processing the timely information such as the vehicle speed, target vehicle speed, and relative distance. When it is impossible to change lanes, the lane change auxiliary warning system prompts / warns the driver through visual, auditory and other display devices, and changes lanes cautiously or cannot change lanes. [0003] In the prior art, the lane change auxiliary e...
