Abstract
An electronic control unit is connected to a network in an in-vehicle network system. The electronic control unit includes a first control circuit that operates on a first operating system and a second control circuit that operates on a second operating system. The first control circuit is connected to the network via the second control circuit. The second control circuit performs a first determination process on frames to determine conformity of the frames with a first rule. Upon determining that the frames conform to the first rule, the second control circuit transmits contents of the frames to the first control circuit. The first control circuit performs a second determination process on the contents of the frames to determine conformity with a second rule. The second rule is different from the first rule.
