1. A vehicle-mounted relay device that relays data flowing through a vehicle-mounted network mounted in a vehicle, comprising:
a CAN communication unit connected to a first bus for performing CAN communication; and
an Ethernet communication unit connected to a second bus for performing Ethernet communication,
a control unit that controls processing relating to relaying of the data,
the control unit derives a threshold relating to a state of each of the first bus and the second bus of the vehicle-mounted network, the state of the vehicle-mounted network being information transmitted using CAN communication directed to the driving state of the vehicle,
determines, based on the derived threshold, an abnormality in the vehicle-mounted network; and
wherein the threshold relating to the state of the vehicle-mounted network includes a threshold relating to a correlation value between states of communication respectively performed with the CAN communication unit and the Ethernet communication unit, and wherein modification of the derived threshold is restricted and the control unit cancels the restriction based on a cancellation condition.
