Abstract

The embodiment of the invention provides a driving path planning method and device and a vehicle. The method comprises the steps of determining at least one reference curve covering a first length range, and selecting a target reference curve covering the first length range from the at least one reference curve covering the first length range; extracting a to-be-adjusted curve covering a second length range from the target reference curve covering the first length range; processing the to-be-adjusted curve based on the safety parameters in the second length range to obtain an adjusted curve; and determining a driving path covering the first length range based on the adjusted curve and the target reference curve. The problems are solved that the complexity of actual traffic cannot be considered and the path planning is influenced by the precision of sampling points.

Description

technical field [0001] The present invention relates to the technical field of unmanned driving control, in particular to a driving path planning method, device and vehicle. Background technique [0002] Traditional automatic driving trajectory planning methods usually use dynamic programming as an after-the-fact evaluation to solve discrete optimization problems without failure, but this will cause the problem that the quality of the solution is greatly affected by the sampling accuracy; another way is the two Sub-planning approach, however, has the problem of being difficult to represent the complexity of actual traffic scenarios. Contents of the invention [0003] Embodiments of the present invention provide a driving path planning method, device, and vehicle to solve the problem that the complexity of actual traffic cannot be considered and the path planning is greatly affected by the accuracy of sampling points. [0004] In a first aspect, an embodiment of the presen...
