Abstract

Provided are a driving path planning apparatus and a method for an autonomous vehicle. The driving path planning apparatus for an autonomous vehicle includes a driving information obtainer to obtain crossroad information, current velocity, and velocity setting of the vehicle. A global path planner plans a base frame, and an environment recognizer recognizes obstacle on a path and lane information of the vehicle. The apparatus also includes a velocity profile generator to generate a velocity profile for the vehicle, using current velocity and velocity setting, a candidate path planner to plan candidate paths for the vehicle, using velocity profile and base frame, and a path selector to check whether or not the candidate paths have collision risks and select one candidate path of the candidate paths as a driving path for the autonomous vehicle.

Description

[0001] Cross-references to related applications [0002] This application is based upon and claims the benefit of priority from Korean Patent Application No. 10-2014-0157366 filed with the Korean Intellectual Property Office on November 12, 2014, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The present disclosure relates to a driving route planning device and method for an autonomous vehicle (autonomous vehicle, self-driving vehicle), and more particularly, relates to such a driving route planning device and method for an autonomous vehicle, that is, capable of reflecting The route candidate group of vehicle speed changes and determines whether there is a risk of collision with obstacles on the planned route to plan a safe driving route. Background technique [0004] An autonomous vehicle is one that follows a map-based driving route. However, when there are variables such as obstacles on the driving route, the autonomous vehi...
