Abstract
A vehicular autonomous driving system includes a time division multiplexed (TDM) bus, an autonomous driving (AD) controller coupled to the TDM bus, and a plurality of AD sensors coupled to the TDM bus. The AD sensors are configured to collect AD data and transmit collected AD data to the AD controller on the TDM bus in an assigned time slot at a first power level. A first AD sensor of the plurality of AD sensors is configured to, based upon collected AD data, detect an AD emergency event. In response to the detection, the first AD sensor is configured to transmit an AD emergency message on the TDM bus in a non-assigned time slot and at a second power level that exceeds the first power level. The AD sensor may transmit the AD emergency message in a particular sub-slot of the non-assigned time slot.

A method comprising:
- receiving, by a processor, first autonomous driving data from at least one autonomous driving sensor of a plurality of autonomous driving sensors in communication with an autonomous vehicle;
- transmitting, by the processor, data at a first power level to a second processor associated with the autonomous vehicle;
- detecting, by the processor, an autonomous driving event associated with the autonomous vehicle;
- and
- transmitting, by the processor, an autonomous driving message to the second processor at a second power level that is different than the first power level.
An autonomous vehicle comprising:
- a plurality of autonomous driving sensors configured to collect autonomous driving data;
- and
- a processor in communication with the plurality of autonomous driving sensors, the processor configured to:
- receive first autonomous driving data from at least one autonomous driving sensor of a plurality of autonomous driving sensors in communication with an autonomous vehicle;
- transmit data at a first power level to a second processor associated with the autonomous vehicle;
- detect an autonomous driving event associated with the autonomous vehicle;
- and
- transmit an autonomous driving message to the second processor at a second power level that is different than the first power level.
A non-transitory computer-readable medium having a set of instructions, that when executed, cause a processor to:
- receive first autonomous driving data from at least one autonomous driving sensor of a plurality of autonomous driving sensors in communication with an autonomous vehicle;
- transmit data at a first power level to a second processor associated with the autonomous vehicle;
- detect an autonomous driving event associated with the autonomous vehicle;
- and
- transmit an autonomous driving message to the second processor at a second power level that is different than the first power level.
