Patent number: 11592360Abstract: A method for testing a technical system. Tests are carried out with the aid of a simulation of the system. The tests are evaluated with respect to a fulfillment measure of a quantitative requirement on the system and different error measures of the simulation. On the basis of the fulfillment measure and each of the error measures, a classification of the tests is carried out as either reliable or unreliable case by case. A selection among the error measures is made on the basis of a number of the tests classified as reliable.Type: GrantFiled: March 8, 2021Date of Patent: February 28, 2023Assignee: Robert Bosch GmbHInventors: Christoph Gladisch, Ji Su Yoon, Joachim Sohns, Philipp Glaser, Thomas Heinz, Daniel Seiler-Thull
