1. A safety control method for an autonomous driving assistance system, comprising:
receiving a status signal regarding a driver so as to determine a reasonably foreseeable indirect misuse (RFIM) event;
receiving a particular system event and/or system fault; and
calculating, with reference to a degree of severity of the particular system event and/or system fault, a failure rate related to the RFIM event; and
determining, on the basis of the failure rate, whether a safety of the intended functionality (SOTIF)-related residual risk in the autonomous driving assistance system is acceptable.
