Embodiment Construction

[0044] In the following, some exemplary embodiments are simply described. As will be appreciated by those skilled in the art, the described embodiments can be modified in a variety of different ways without departing from the spirit or scope of the invention. Thus, the drawings and description are considered to be essentially exemplary rather than limiting.

[0045] The embodiment of the present invention provides a path planning method, based on the starting point and the end point generation path planning result, and again for the lane contained in the path planning result, the optional lane is determined based on the optional lane to obtain the extended path planning result, will eventually expand The path planning results are set to the same pass area in the path planning result.

[0046] In one embodiment, if figure 1 As shown, a path planning method includes:

[0047] Step 101: Based on the starting point and the end point, the path planning result is generated; where the p...

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 field of driverless control technology, and more particularly to a path planning method, a device, and a vehicle. Background technique [0002] In the unmanned drive, through the global path plan for high-precision maps, the global path is provided to the unmanned car, which is the basis for ensuring the reasonable driving decision of the driver. With high-precision map, the global path planning method is usually only available, and the path planning result of the lane level is usually provided, but the path planning results obtained in this way are not guaranteed. Inventive content [0003] Embodiments of the present invention provide a path planning method, apparatus, and vehicle to solve problems that cannot guarantee the corrugated changes in the prior art. [0004] In the first aspect, the embodiment of the present invention provides a path planning method, including: [0005] Based on the starting point and the en...
