Vehicle lane changing control method and system

Abstract

The invention discloses a vehicle lane changing control method and system, and belongs to the field of vehicle safety. The method comprises the steps that the distance datum of a vehicle about to change a lane is obtained and is the distance between the vehicle and a barrier which is located behind the vehicle and is closest to the vehicle, and the barrier is located in a lane which the vehicle is to go into; whether the distance datum is smaller than a bumping distance threshold value or not is judged; if the distance datum is smaller than the bumping distance threshold value, whether the vehicle is located in a dangerous zone or not is judged, and the dangerous zone is the zone that distance between the zone and the central line of the lane where the vehicle is located currently exceeds a preset distance threshold value; and if the vehicle is located in the dangerous zone, the vehicle is controlled to run in the direction away from the lane which the vehicle is to go into. The vehicle lane changing control method system provided by the invention is used for controlling the vehicle about to change the lane so that the vehicle can eliminate dangerous conditions by itself when bumping danger is about to happen to the vehicle about to change the lane during lane changing, and therefore the potential safety hazards of the vehicle in the lane changing process are removed.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a vehicle lane change control method and system. Background technique [0002] In recent years, with the development of technology and economy, the number of vehicles has also increased simultaneously. Along with the increase of vehicles on the highway, traffic accidents have become more and more common in people's daily life. In traffic accidents, many accidents are caused by the driver colliding with or scratching the rear vehicle when changing lanes. Therefore, how to ensure the safe lane change of vehicles and reduce the traffic accidents in the lane change process has been paid more and more attention by people. [0003] In the prior art, the vehicle can monitor the distance between the vehicle behind and itself during the lane change, and feed it back to the driver. When the distance between the vehicle behind and itself is relatively close, the vehicle can issue an alarm to...

Problems solved by technology

In the actual environment, when the alarm sounds, the driver often needs a certain amount of time to react, which makes the driver unable to rule out the danger of changing lanes at the first time. Therefore, this method still has certain potential safety hazards.
