Abstract: Each ECU transmits a frame to a frame generator. Then, the frame generator decomposes data contained in the received frame and then stores the data into a buffer memory, for each message type. The frame generator generates a message containing data to be transmitted to each ECU, and then transmits the message. Based on the state of a signal indicating the electric power supply status, the frame generator controls the permission or non-permission of transmission processing such that frame transmission is not performed to the ECU to which electric power supply from an electric power supply control device. When any communication part has received an abnormal frame, the frame generator does not include data contained in frames received afterward by the communication part, into a frame generated for other communication parts.

Abstract: In a network in which a plurality of ECUs are connected to one another with a common bus, one or more slots are allocated to each ECU in advance, and the plurality of ECUs cyclically transmit messages in an order prescribed in relation to the slots. When each ECU transmits the message related to one slot, each ECU creates and transmits a message including data to be transmitted to other ECUs, and information representing respectively a success/failure of the message reception related to other slots. Each ECU checks information of ACK field included in a message received during one cycle from message transmission related to one slot to a next message transmission related to said one slot. When the message related to one slot is not accurately received by the other ECUs, retransmits the message in the next transmission related to said one slot.

Abstract: It is expected to provide a communication apparatus, relay apparatus, communication system and communication method for effectively performing a communication timing adjustment when a collision has occurred on a communication line, efficiently reducing the communication collision with reducing processing loads on each apparatus, for making each apparatus effectively perform the transmission timing adjustment, and for improving the communication efficiency. ECUs are connected to communication lines with a bus topology. A relay apparatus is connected to the communication lines, obtains a time distribution based on a number of messages transmitted to the communication lines. When the bias occurs in the transmission timings, the relay apparatus transmits an instruction message that instructs to perform the timing adjustment for messages transmitted between the ECUs. In addition, it is determined whether a message to be relayed is held. When it is determined that such a message is held, the instruction message is transmitted.
