Abstract

In one embodiment, in response to a route from a source location to a target location, the route is analyzed to identify a list of one or more driving scenarios along the route that match one or morepredetermined driving scenarios. The route is segmented into a list of route segments based on the driving scenarios. At least one of the route segments corresponds to one of the identified driving scenarios. A path is generated based on the route segments for driving an autonomous driving vehicle from the source location to the target location. The path includes a number of path segments corresponding to the route segments. At least one of the path segments of the path is determined based on a preconfigured path segment of a predetermined driving scenario associated with the path segment, without having to calculating the same at real time.

Description

technical field [0001] Embodiments of the present disclosure generally relate to operating an autonomous vehicle. More specifically, embodiments of the present disclosure relate to driving scene-based lane guidance lines for path planning of autonomous vehicles. Background technique [0002] Vehicles operating in an autonomous mode (e.g., driverless) can free passengers (especially the driver) from some driving-related duties. When operating in autonomous mode, the vehicle can navigate to various locations using on-board sensors as well as high-definition maps, allowing the vehicle to drive with minimal human interaction or in some cases without any passengers. [0003] When planning a route from a starting location to a destination location, the reference line of the route is important since it is the final goal of the path along which the autonomous vehicle is driven. However, a good path guideline can make a big difference from an ordinary guideline centered on the road...
