Abstract
Systems, methods, and apparatuses are discussed that enable robust, high-speed communication of sensor data. One example system includes a sensor bus, an electronic control unit (ECU), and one or more sensors. The ECU is coupleable to the sensor bus and configured to generate a synchronization signal, and is configured to output the synchronization signal to the sensor bus. The one or more sensors are also coupleable to the sensor bus, and at least one sensor of the one or more sensors is configured to sample sensor data in response to the synchronization signal and to output the sampled sensor data to the sensor bus.

1-21. (canceled)
A system, comprising:
- a sensor bus;
- an electronic control unit (ECU) couplable to the sensor bus and configured to generate a synchronization signal, wherein the ECU is configured to output the synchronization signal to the sensor bus;
- and
- one or more sensors couplable to the sensor bus, wherein at least one sensor of the one or more sensors is configured to acquire respective sensor data and to output a respective digital representation of the respective sensor data in a respective frame to the sensor bus,
- wherein the respective sensor data represented by the respective digital representation has a predetermined latency relative to the synchronization signal.
A sensor, comprising:
- one or more components to:
- acquire sensor data;
- receive a synchronization signal;
- and
- output a digital representation of the sensor data in a respective frame,
- wherein the sensor data represented by the digital representation has a predetermined latency relative to the synchronization signal.
An electronic control unit (ECU), comprising:
- one or more components to:
- generate a synchronization signal;
- output the synchronization signal to one or more sensors via a sensor bus;
- and
- receive at least one respective digital representation of respective sensor data in a respective frame from the one or more sensors via the sensor bus,
- wherein the respective sensor data represented by the digital representation has a predetermined latency relative to the synchronization signal.
