In-vehicle equipment, anomaly detection method and anomaly detection program

摘要

PROBLEM TO BE SOLVED: To provide an in-vehicle device, an abnormality detection method and an abnormality detection program capable of more stably performing time synchronization between in-vehicle devices. SOLUTION: An in-vehicle device synchronizes time between the other device and its own in-vehicle device based on a data propagation delay time between another device which is another in-vehicle device and its own in-vehicle device. Is performed, the processing unit that receives the request information for requesting the time information used for updating the propagation delay time from the other device and transmits the time information to the other device, and the abnormality related to the time synchronization. It is equipped with a detection unit that detects and acquires information about the detected abnormality. [Selection diagram] Fig. 2
