    From the patent:

    When an autonomous driving emergency event is detected by an autonomous driving sensor…the [sensor] transmits the autonomous driving emergency message in a non-assigned time slot at a higher transmit power level than a transmit power level of an autonomous driving sensor…Because the autonomous driving emergency message is transmitted at a higher power level than the transmission from the autonomous driving sensor, the transmission from the autonomous driving sensor may be treated as background noise by the autonomous driving controller to thereby receive and decode of the autonomous driving emergency message.

    ...if an emergency transmission is detected…the autonomous driving sensor ceases transmitting autonomous driving data. Such cessation may continue for one assigned time slot, for more than one assigned slots, and/or until the autonomous driving sensor receives direction from the autonomous driving controller to continue transmitting autonomous driving data or receives a new…bus time slot assignment from the autonomous driving controller. During this time period…the autonomous driving sensor continues to collect and buffer autonomous driving data.

    This patent seems a bit of a waste of time.

    It is saying that the sensors themselves are intelligent enough to know when an emergency event is happening, and their decision overrides whatever the actual ECU has got queued up by "shouting" louder over the bus.

    Prior art on this would include "human beings", for example, when you step on a pin, the pain signal causes an instant reaction which overrides whatever you were planning to do.

    As for utility, the ECU is probably in a much better state to determine whether an emergency is about to happen than a single sensor. And there are already sensors that are dedicated to determining if an emergency is *actually" happening.
