A COMPUTER-IMPLEMENTED METHOD FOR MANAGING AN OPERATIONAL DESIGN DOMAIN S EXPANSION FOR AN AUTOMATED DRIVING SYSTEM

The present invention is related to a computer-implemented method (100) for managing an Operational Design Domain (ODD) expansion for an Automated Driving System (ADS) of a vehicle. The method (100) comprises: obtaining (S102) a plurality of scenario parameters defining the environment of the vehicle, wherein each scenario parameter corresponds to a respective condition of the ODD; in response to the plurality of scenario parameters fulfilling the plurality of ODD conditions: allowing (S104) the ADS to be activated or to remain active; in response to one or more scenario parameter(s) not fulfilling one or more ODD condition(s): querying (S106) a logic formula based on the obtained plurality of scenario parameters, such that if at least one soft constraint of the logical formula is satisfied without violating any hard constraints of the logical formula, the ADS fulfils a plurality of predefined safety requirements; determining (S108), based on the logic formula and the obtained plurality of scenario parameters, a set of values of one or more variable state parameters which satisfies at least one soft constraint without violating any hard constraints; and allowing (S112) the ADS to be activated in a degraded mode or to switch to a degraded mode by limiting one or more variable state parameters of the ADS to conform to the determined set of values of the one or more variable state parameters.
