1. A computer-implemented method for terminating a scenario-based test process of a driver assistance system, the method comprising:
performing a cycle of a test process, wherein the test process includes performing at least one test of the driver assistance system;
determining a set of critical test cases corresponding to the performed cycle, wherein respective critical test cases of the set correspond to respective parameter combinations of driving situation parameters spanning a metric parameter space;
determining a distance between the set of critical test cases and a previous set of critical test cases corresponding to a previous cycle of the test process, or determining a distance between the set of critical test cases and a predefined set of critical test cases;
determining whether to terminate the test process or to perform a subsequent cycle of the test process based on comparing the determined distance to a preset limit; and
terminating the test process or performing the subsequent cycle of the test process based on the determination of whether to terminate the test process or to perform the subsequent cycle of the test process;
wherein the test process comprises an expanded surrogate model generation method, and wherein the cycle of the test process comprises a design phase, a model generation phase, and a test phase; and
wherein the test process having the expanded surrogate model generation method is used to approximate rating functions of automated vehicles.
