DUAL PATH ETHERNET-BASED SENSOR DEVICE FAULT MONITORING

In an embodiment, an autonomous driving vehicle (ADV) processes a set of sensor data concurrently by both a first computing unit and a second computing unit, wherein the set of sensor data is generated by a sensor. The first computing unit formats the set of sensor data into a set of message data. The second computing unit determines whether the set of sensor data indicates a control path fault. The second computing unit reports the control path fault responsive to determining that the set of sensor data indicates the control path fault.
