Embodiment Construction

[0044] 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.

[0045] An embodiment of the present invention provides a path planning method, which generates a path planning result based on the starting point and the end point, and then determines optional lanes for the lanes included in the path planning result, obtains the expanded path planning result based on the optional lanes, and finally converts the expanded The lanes with the same attributes in the path planning results are set as the same traffic area.

[0046] In one embodiment, as figure 1 As shown, a path planning method is provided, the method comprising:

[0047] Step 101: Based on the start point and ...

Abstract

The invention provides a method and device for route planning and a vehicle. The method for the route planning comprises the steps that a route planning result is generated based on a starting point and an end point, wherein the route planning result comprises at least two lanes, and adjacent lanes in the at least two lanes are adjacent front and back; based on the at least two lanes containing inthe route planning result and attributes and a left-right adjacent relationship of each lane, an optional lane is obtained, wherein the attributes of the lane comprise variable lane attributes and non-variable lane attributes; the optional lane is added to the route planning result, a extended route planning result is obtained, and at least one traffic area containing lanes with the same attributes is determined. The problem that the ability of lane changing cannot be guaranteed by a driverless vehicle is solved.

Description

technical field [0001] The present invention relates to the technical field of unmanned driving control, in particular to a path planning method, device and vehicle. Background technique [0002] In the field of unmanned driving, providing a global path for unmanned vehicles through global path planning using high-precision maps is the basis for ensuring that unmanned vehicles complete driving decisions reasonably. The global path planning method using high-precision maps usually only provides lane-level path planning results. However, the path planning results obtained in this way cannot guarantee the lane-changing ability of unmanned vehicles. Contents of the invention [0003] Embodiments of the present invention provide a path planning method, device, and vehicle to solve the problem in the prior art that the ability to change lanes of an unmanned vehicle cannot be guaranteed. [0004] In a first aspect, an embodiment of the present invention provides a path planning ...
