AUTONOMOUS DRIVING VEHICLE REDUNDANT HOLDING CONTROL TO PREVENT ROLLING

Data is received from a plurality of sensors mounted on an ADV being held to a standstill. A status of the ADV including a rolling speed of the ADV is detected based on the data from the plurality of sensors. One of a primary brake or a secondary brake is activated, in response to detecting the status of the ADV being a first status including the rolling speed being higher than zero and lower than a first predetermined speed threshold. An electronic parking brake is activated, in response to detecting the status of the ADV being a second status including the rolling speed being higher than the first predetermined speed threshold and lower than a second predetermined speed threshold. An engine brake may be used to reduce the crash damage, and a warning message (e.g., Message-4) may be generated.
