Motor vehicle traffic lane selection method and device, and vehicle

Abstract

The invention discloses a motor vehicle traffic lane selection method, which is executed on a motor vehicle and comprises the following steps of: acquiring driving information of surrounding vehicles in a preset range around the motor vehicle, wherein the driving information comprises geographical location information of the vehicles; determining a lane where the surrounding vehicles are located according to the geographical location information of the surrounding vehicles; for the surrounding vehicles in the current lane and a variable lane which are the same as a planned driving direction of the motor vehicle, acquiring a historical acceleration model of the surrounding vehicles passing an intersection; determining a predicted traffic flow acceleration of the lane according to the historical acceleration model of each surrounding vehicle located on the same lane; and selecting one lane from the current lane and the variable lane as a recommended lane for output according to the predicted traffic flow acceleration of the current lane and the variable lane. According to the motor vehicle traffic lane selection method, a driver can be helped to select a more efficient traffic lane, and the traffic jam at the intersection can be effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of vehicle driving, and more specifically, to a method and device for selecting a vehicle lane, and a vehicle. Background technique [0002] With the continuous increase of the number of motor vehicles on the road, in order to alleviate road traffic congestion, the road has also become wider, and multiple lanes are generally set in the same direction. When there are multiple lanes, in order to drive more efficiently and relieve traffic pressure, the driver will choose the lane with relatively faster traffic speed during driving. But for the judgment of which lane is faster, the driver can only choose the lane by simply observing the driving situation of the vehicle in front. The result of this lane selection method is obviously not necessarily a lane that can drive more efficiently. At the same time, the emergence of multiple lanes also increases the traffic pressure at the intersection. The lane se...

Problems solved by technology

[0003] In the prior art, there is a method of lane recommendation using the current speed and acceleration of the vehicle and the current speed and acceleration of other nearby vehicles. This method only recommends fast lanes based on current speed and acceleration predictions, and cannot obtain more stable, fast lanes based on more data. Effective recommendation, but there are also problems of continuous recommended lanes and frequent lane changes, which increase the possibility of traffic jams and driving risks

Furthermore, the recommended lane may also be a mixed lane, such as a mix of going straight and turning left, mixing going straight and turning right, mixing turning left and turning, etc. At this time, the driver cannot pass quickly and may cause congestion in the mixed lane
