Problems solved by technology

In the complex parking lot scene, the reference driving line will be updated by the algorithm every time the vehicle obtains a local map. The calculation difficulty of the reference driving line is different for road sections with different driving difficulties. The same reference driving line generation algorithm is used for all road sections. It will increase the occupation of system resources and increase the time-consuming algorithm

Abstract

The present invention provides a method, system, terminal and storage medium for quickly generating a reference driving line, which divides the route planning points for road sections with different difficulties according to the driving difficulty, and obtains the driving reference driving line by geometrically processing the part with low driving difficulty; The part with high driving difficulty is combined with the vehicle dynamics constraints to obtain the driving reference driving line with the Hybrid A star algorithm, and then the driving reference driving lines of each part are spliced ​​to form a complete driving reference driving line. This method has a low system resource occupation rate and the algorithm Time consuming.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a method, system, terminal and storage medium for quickly generating a reference driving line. Background technique [0002] The reference driving line is a common module in the map route planning service. After obtaining the user's starting location and obtaining the user's input destination location, the map will generate a global path. The global path is composed of sparse The road nodes along the route are composed of road nodes along the route, and then these road nodes along the route are connected in series to form a global path (global path) by the path planning line from the starting position to the end direction of the destination position. [0003] The global path (global path) is directly connected between the nodes, and the actual driving path of the vehicle needs to conform to the vehicle body dynamics under different road scenarios and under the infl...
