Autonomous Vehicle Sensor Timing Synchronization for Accurate Data Correlation

The patent divides the synchronization system into distinct functional modules: a high-precision time generation unit that produces reference timing signals, a distribution unit that propagates these signals to multiple sensors, and individual sensor units that capture data based on received timing cues. This segmentation allows each module to be optimized independently while achieving overall system synchronization with microsecond or nanosecond precision.

The patent introduces a central time generation unit as an intermediary that mediates between the clock source and multiple sensors. This intermediary distributes synchronized timing signals to all sensors, ensuring they acquire data at precisely aligned time points without requiring complex peer-to-peer synchronization protocols between sensors themselves.

The patent implements preliminary action by having the time generation unit prepare and distribute reference timing signals to all sensors before the actual data acquisition cycle begins. Each sensor receives and acknowledges the timing signal in advance, ensuring they are all ready to capture data simultaneously at the predetermined time point, which greatly enhances detection reliability.

The patent incorporates feedback mechanisms where sensors acknowledge receipt of timing signals and report their status back to the central control unit. This feedback loop allows the system to verify that all sensors are properly synchronized and functioning, enabling real-time adjustment if any sensor falls out of sync, thus maintaining high detection accuracy.
