Method, electronic device, and autonomous driving system for error event analysis

An electronic device for error event analysis, comprising a processor and a memory coupled to the processor and storing program instructions, wherein when being executed by the processor, the program instructions cause the processor to:

• in response to an error event of an autonomous driving system, feed a sequence of signal states, related to the error event, collected from the autonomous driving system into a prediction model, wherein the prediction model is trained based on signal states collected from a plurality of autonomous driving systems and the prediction model is used for predicting, based on a first signal state, a second signal state, the first signal state representing signals collected at a first time, and the second signal state representing signals collected at a second time succeeding the first time;
• convert the error event into an event signal state having signal values at an event time;
• compare the second signal state with the event signal state;
• and
• in response to the second signal state matching the event signal state, trace the error event back to the first signal state as a root cause.
