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 present application discloses a method, device and equipment for assisting lane change. By first receiving the vehicle state information of surrounding vehicles within a preset range, the vehicle state information includes position, driving direction, speed and acceleration; according to the current The vehicle state information of the vehicle determines the lane change association area, and then determines the lane change cooperation area in the lane change association area according to the steering direction; among the surrounding vehicles, the associated lane change vehicles in the lane change cooperation area are determined according to the vehicle state information of the surrounding vehicles , and then send the steering direction to the associated lane-changing vehicle, so that the associated lane-changing vehicle can determine whether it is a cooperative lane-changing vehicle according to its own vehicle status information; finally, receive the lane-changing prompt information sent by the cooperative lane-changing vehicle, and according to the lane-changing prompt information Perform a lane change. Through the coordinated auxiliary lane change of surrounding cooperative lane change vehicles, the lane change safety of the current vehicle can be ensured, vehicle collisions can be avoided, and the efficiency of vehicle lane change can be 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...
