METHOD FOR OPERATING AN AUTONOMOUS DRIVING VEHICLE

Method for real-time monitoring of a safety redundancy autonomous driving system operating within a predefined risk tolerable boundary includes calculating a zone failure risk score for each of predetermined zones based on a sensor failure risk score associated with each of sensors mounted on the ADV. The predetermined zones being defined based on a sensor layout of the sensors. A sensor capability coverage of the ADV is determined based on the zone failure risk score associated with each of the predetermined zones. A drivable area of the ADV is determined based on the sensor capability coverage in view of map data associated with a current location of the ADV. A trajectory is planned based on the drivable area to autonomously drive the ADV to navigate a driving environment surrounding the ADV.
