Operating scenarios for testing Automated Driving Systems in challenging conditions

During planning of a prototype automated driving system's (ADS) testing, the operating scenarios of the systems to be tested are usually described in an abstract, linguistic way as a function of the system's Operational Design Domain (ODD). In this paper, a methodology for operating scenarios definition that integrates ODD conditions under focus, as developed in the European project Hi-Drive, will be presented. For this pur pose, two sub-types of ODD specification will be considered for testing the integration
of a Hi-Drive enabler technology in the ADS under test: a) the ODD for testing “AD performance”, in which we test if higher AD performance and prolonged AD usage can be achieved under nominal ODD conditions and b) an extended ODD for testing “AD availability”, where additional challenging operating conditions are tested which extend the nominal ODD of the AD system under test.
