Abstract

Embodiments of the present invention provide a lane selection method, device, and computer-readable storage medium for an unmanned vehicle. The lane selection method for the unmanned vehicle includes: calculating a lane metric parameter for each lane on the current road section on which the host vehicle is traveling; calculating each of the lane metric parameters of each lane respectively; selecting according to the result of the calculation The target lane where the host vehicle travels. The embodiment of the present invention selects the most suitable lane for driving according to the calculation result of the lane metric parameter, and helps the unmanned vehicle to make a decision according to the real-time road conditions and the driving intention of the unmanned vehicle, so that the unmanned vehicle is safer and smoother.

Description

technical field [0001] The present invention relates to the technical field of unmanned vehicles, and in particular, to a lane selection method, a device and a computer-readable storage medium for an unmanned vehicle. Background technique [0002] The unmanned vehicle system in the prior art uses a planning module to plan the driving route. For example, in the planned driving route, when driving to a certain position on the current lane, it should drive in the lane. However, planning a driving route usually only plans where to change lanes according to the driving destination, and does not make comprehensive judgments based on road conditions and other information. In actual road conditions, if the target lane for lane change is blocked, it is impossible to drive according to the planned driving route. For another example, planning a driving route usually only plans which road or lane to drive on according to the driving destination. In the scenario of fork road selection, ...
