Embodiment Construction

[0039] In the following, only some exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.

Abstract

The embodiment of the invention provides an automatic driving method and device and a storage medium. The automatic driving method is applied to a vehicle with an automatic driving function and comprises the following steps of determining the edge and width of a current road; dividing at least two lanes for the road according to the edge and width of the road and the preset width of a single lane;controlling running of the vehicle according to the divided lanes, wherein at least partial adjacent lanes are overlapped with each other. According to the automatic driving method, the number of thereasonable lanes can be automatically calculated, the lanes can be divided, and the number and the lane information are fed back to a decision-making and planning module for utilization so that the automatic driving method can immediately adapt to automatic driving on the road where lane lines cannot be detected.

Description

technical field [0001] The present invention relates to the field of automatic driving, in particular to an automatic driving method, device and storage medium. Background technique [0002] Autonomous vehicles generally detect lanes based on clearly defined lane lines on the road and plan autonomous driving paths. [0003] However, on roads such as country roads or campus roads, where there are often no clear lane lines, or where lane lines are obscured (for example, due to weather), it is difficult for autonomous driving path planning and decision-making algorithms to adapt. In the prior art, there is no solution for how to perform automatic driving on such roads where lane lines cannot be detected. Contents of the invention [0004] Embodiments of the present invention provide an automatic driving method, device, and storage medium to solve the problem in the prior art that roads with lane lines cannot be detected, so that automatic driving cannot be performed. [000...
