Embodiment Construction

[0128] In order to make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0129] An exemplary embodiment of the present disclosure provides a smart car lane change control method, such as figure 1 As shown, the processing flow of the method may include the following steps:

[0130] Step S110, judging whether the speed of the smart car is greater than the speed of the nearest vehicle in front of the smart car on the current driving lane.

[0131] Step S120, when the speed of the smart car is greater than the speed of the nearest vehicle in front of the current driving lane of the smart car, obtain the first distance, relative speed and second distance between the smart car and the closest vehicle behind in the adjacent lane, the The first distance is the straight-line distance between the smart car and the rear nearest vehic...

Abstract

The invention provides a control method of intelligent car lane changing. The control method comprises the steps that whether the speed of an intelligent car is higher than the speed of a closest vehicle in front of the intelligent car on a current driving lane of the intelligent car or not is judged; when the speed of the intelligent car is higher than the speed of the closest vehicle in front ofthe intelligent car on the current driving lane of the intelligent car, a first distance, a relative speed and a second distance of the intelligent car and a closest vehicle behind on an adjacent lane are obtained; a safe vehicle distance is obtained according to the speed of the intelligent car; a lane changing permitting time is obtained according to the first distance, the relative speed, thesecond distance and the safe vehicle distance; and if the lane changing permitting time is larger than a preset lane changing time, the intelligent car is controlled to change to the adjacent lane. Byjudging whether arequirement for the lane changing time is met or not, the intelligent car is controlled to change the lanes, the condition that the intelligent car is automatically controlled to change to the adjacent lane is achieved, and the intelligent car is enabled to change the lanes safely and efficiently.

Description

technical field [0001] The invention relates to the field of smart car control, in particular to a method and device for controlling lane change of a smart car. Background technique [0002] With the increase of vehicles on the road, traffic accidents are becoming more and more common in people's daily life. In many traffic accidents, most of them are rear-end collisions and scratches caused by the driver's wrong lane change. Therefore, how to ensure the safe lane change of vehicles has attracted more and more attention. [0003] In the prior art, the driver judges whether the speed of the vehicle in the adjacent lane and the distance from the own vehicle meet the requirements for changing lanes. When the requirements for changing lanes are met, the driver controls the steering wheel to change the vehicle from the current lane to the adjacent lane. Lane. [0004] The inventor finds that there are at least the following problems in the prior art: [0005] When judging whet...
