specific Embodiment approach

[0111] The lane change association area is related to the vehicle status information of the current vehicle. In a possible implementation, the embodiment of the present application provides a specific implementation of S202, which specifically includes the following four steps:

[0112] A1: Take the position of the current vehicle as the origin of the coordinates, take the driving direction of the current vehicle as the direction of the positive semi-axis of the vertical axis of the coordinates, and take the straight line perpendicular to the vertical axis of the coordinates as the horizontal axis of the coordinates to establish a coordinate system.

[0113] see image 3 As shown, this figure is a schematic diagram of the lane change associated area provided by the embodiment of the present application.

[0114] When determining the lane change associated area, a coordinate system can be established based on the current vehicle position and driving direction. Specifically, th...

Abstract

The embodiment of the invention discloses a method, device and equipment for realizing auxiliary lane changing, and the method comprises the steps: firstly receiving vehicle state information of surrounding vehicles in a preset range, wherein the vehicle state information comprises the position, driving direction, speed and acceleration; determining a lane changing associated area according to thevehicle state information of the current vehicle, and determining a lane changing cooperation area in the lane changing associated area according to the steering direction; in the surrounding vehicles, determining associated lane changing vehicles in the lane changing cooperation area according to the vehicle state information of the surrounding vehicles, and then sending the steering directionsto the associated lane changing vehicles, so that the associated lane changing vehicles determine whether the vehicles are cooperation lane changing vehicles or not according to the vehicle state information of the associated lane changing vehicles; and finally, receiving lane changing prompt information sent by the cooperative lane changing vehicle, and executing lane changing operation accordingto the lane changing prompt information. Through the cooperative auxiliary lane changing of the surrounding cooperative lane changing vehicles, the lane changing safety of the current vehicle can beensured, the collision of the vehicles is avoided, and the lane changing efficiency of the vehicles is improved.

Description

technical field [0001] The present application relates to the field of vehicle control, in particular to a method, device and equipment for realizing auxiliary lane change. Background technique [0002] During the driving process of the vehicle, it is often necessary to perform a lane-changing operation on the vehicle according to the driving direction or the state of the lane. [0003] When a vehicle changes lanes, it is necessary to judge the driving state of the surrounding vehicles, and perform the lane change operation when a space for safe lane changes is ensured. At present, drivers need to observe the driving status of surrounding vehicles when preparing to change lanes, and rely on personal experience to judge whether the vehicle can change lanes safely. However, relying on the driver's personal experience is difficult to predict the driving state of the vehicle, nor can it accurately judge the distance between vehicles. It may take a long time to successfully chan...
