AI Technical Summary
There is a need for more efficient solutions to develop, verify, and validate path planning functions for Automated Driving Systems (ADSs) to ensure safer and more performant systems, while allowing for more frequent releases without compromising safety or increasing costs, size, or power consumption.
A computer-implemented method for closed-loop evaluation of path planning modules in ADS-equipped vehicles, which involves obtaining candidate paths from multiple modules, determining convergence criteria, selecting and executing a candidate path, and evaluating the modules based on the executed path, while also considering exposure needs and operational design domains.
This solution enables more frequent and cost-effective releases of new and updated path planning features by optimizing validation and test coverage, reducing the need for dedicated test vehicles, and ensuring safety and performance standards are met.
