  • Patent number: 11140052
    Abstract: In an anomaly detection by an electronic control unit connected to an other electronic control unit via a communication network, a data frame is received from the other electronic control unit, and a reception interval is calculated between a first data frame and a second data frame received immediately before the first data frame. A determination value for determining whether the data frame is anomalous is updated by adding a predetermined value to the determination value when the reception interval is equal to or less than a threshold value, and the data frame is determined to be anomalous when the determination value exceeds a limit value.
