The widespread adoption of autonomous driving significantly enhances societal operational efficiency and road safety. However, the reliability and safety of autonomous driving systems themselves are critically emphasized. Autonomous vehicles are equipped with a series of safety-related sensors (domain controllers, LiDAR, cameras, mmWave radar, etc.), ensuring safety through redundancy. Vehicles require precise time synchronization to ensure these sensors and devices accurately capture environmental information, enabling high-precision autonomous navigation.
Due to the highly complex operating environments of vehicles such as tunnels, bridges, mountainous regions, and various elevated roads, many environments cannot provide stable time signals.
Chip-level atomic clocks, with their excellent performance, ultra-low power consumption and size, and superior environmental robustness, can provide vehicles with highly stable and precise time signals in real time. This capability assists vehicles in accurately obtaining current location and time information, facilitating the coordinated operation of various sensors and devices.
