摘要： PROBLEM TO BE SOLVED: To provide a failure diagnosis system capable of diagnosing a failure by a diagnosis device for a node in a sleep state in a selective wake-up mode.SOLUTION: A diagnosis assist ECU determines whether or not a frame received from the diagnosis device is a diagnosis frame (S100). When it is the diagnosis frame (S100: YES), a diagnosis object ECU is searched (S110). Then, a starting ID of the diagnosis object ECU is set up in a wake-up frame (S120) and the wake-up frame is transmitted to a bus communication path (S130). The sleeping ECU receives the wake-up frame by a transceiver and compares the starting ID set up in the wake-up frame with an own starting ID. When they match, the transceiver instructs a power circuit to supply power to a CPU.

摘要： PROBLEM TO BE SOLVED: To provide a node which has simple structure and is capable of communication between nodes in a normal mode without activating a node in a sleep mode, and capable of quickly activating a node in the sleep mode as necessary.SOLUTION: Each ECU 10 comprises a first transceiver 12 used for communication between its own ECU 10 and another ECU 10 and, in addition, a second transceiver 13 for transmitting and receiving a differential signal having reversed polarity on a communication path LN relative to a differential signal having normal polarity used for its communication. An ECU 10 uses the second transceiver 13 to transmit and receive an activation signal to transition an operation mode from a sleep mode to a normal mode. In addition, if dominants of a differential signal of the normal polarity and a differential signal of the reversed polarity collide with each other, the dominant of the normal polarity is dominant. This makes it possible to transmit the activation signal at any timing without affecting communication between an ECU 10 in the normal mode and an ECU 10 in the normal mode.

摘要： PROBLEM TO BE SOLVED: To provide a mechanism for efficiently detecting operation abnormality of an on-vehicle network system having NM (Network Management) function.SOLUTION: In an on-vehicle network system 100, nodes 1, 3, 5 and 10 transmit respective sleep start messages to a communication bus when sleep conditions are satisfied by stopping transmission of an NM message while the respective nodes 1, 3, 5 and 10 perform state transition processing (transition processing from a normal state to a power-saving state). A monitoring ECU (Electronic Control Unit) 100B performs abnormality detection processing for detecting abnormality in the state transition processing on the basis of whether the sleep start message is received from each of the nodes 1, 3, 5 and 10. Thus, it is possible to properly detect abnormality not only when the nodes 1, 3, 5 and 10 are in the normal states but also when the bus is in sleeping operation.
