Abstract

The invention provides a control method and device for automatically changing lanes, and a controller. The control method comprises the following steps of detecting a lane changing mode of a travelling vehicle in a current travelling lane, wherein the lane changing mode is a mandatory changing mode or a free changing mode; according to the corresponding relation between a preset lane changing modeand required travelling condition information, obtaining target required travelling condition information corresponding to the lane changing mode; and inputting the target required travelling condition information to a target BP neural network model which is constructed in advance and corresponds to the lane changing mode, and determining the automatic lane changing result. Through the adoption of the control method disclosed by the invention, the problem that in the prior art, the lane changing opportunity cannot be accurately determined, so that the safety during lane changing is low is solved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a control method, device and controller for automatic lane change. Background technique [0002] The sharp increase in car ownership has brought convenience to people's travel, but it has also caused serious economic losses and a large number of casualties. In particular, the wrong judgment made by drivers on the timing of road replacement during the road replacement process is very likely to cause vehicle collisions and accidents. These accidents often lead to traffic delays and traffic jams, resulting in increased travel time for the public. And it has a negative impact on the economy, so determining the exact timing of road change is of great practical significance for improving the safety of changing lanes and improving traffic flow density. [0003] To sum up, there is a problem in the prior art that the safety of lane changing is low due to the inability to accurately determine ...
