Abstract: An electronic control unit is connected to an in-vehicle network bus in an in-vehicle network system. The electronic control unit includes a first control circuit and a second control circuit. The first control circuit is connected to the in-vehicle network bus via the second control circuit over wired communication and/or wireless communication. The first control circuit performs a first determination process on a frame to determine conformity of the frame with a first rule. The second control circuit performs a second determination process on the frame to determine conformity of the frame with a second rule, and, upon determining that the frame conforms to the second rule, transmits the frame to the in-vehicle network bus.

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.

Abstract: An electronic control unit is connected to an in-vehicle network bus in an in-vehicle network system including a plurality of apparatuses that perform communication of frames via the bus. The electronic control unit includes a first control circuit and a second control circuit. The first control circuit is connected to the bus via the second control circuit over wired communication and/or wireless communication. The second control circuit performs a first determination process on a received frame received from the bus to determine the conformity with a first rule related to at least a reception interval, and, upon determining that the received frame conforms to the first rule, executes a predetermined process based on the content of the received frame. The first control circuit performs a second determination process on the received frame, received via the second control circuit, to determine the conformity with a second rule different from the first rule.
