AUTOMATIC GENERATION OF CORNER SCENARIOS DATA FOR TUNING AUTONOMOUS VEHICLES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240034353 titled 'AUTOMATIC GENERATION OF CORNER SCENARIOS DATA FOR TUNING AUTONOMOUS VEHICLES
Simplified Explanation
The abstract of this patent application describes a method for automatically generating corner simulation scenarios. The method involves generating parameter values, determining their validity based on predefined metrics, and performing simulation tasks to simulate a trajectory planner. A performance score is calculated for each simulation task, and if the score is below a threshold, the parameter values are saved for re-tuning the trajectory planner.
