摘要： A data relay device connected with a plurality of networks is provided with a transmission timing adjusting device for adjusting the timing of transmission of data frames. The relay device provides a time zone, in which transmission of new data frame to the network is inhibited immediately after transmission of data frame to the network of the relaying destination. Accordingly, even when the data frame to be relayed to the network is concentrated in the data relay device, the data frame from nodes of the network can be transmitted using the time zone.

摘要： In a network system, each ECU transmits a start control frame when to start, and is started when it receives the start control frame from any other ECU during the stop of its operation. Besides, each ECU transmits a stop control frame cyclically during its operation, and continues its operation in spite of being capable of stopping its operation, while it is receiving the stop control frame from any other ECU. In transmitting each of the frames, each ECU affixes cause information expressive of a start cause or an operation stop incapability cause to the frame. In stopping a network, a supervisory device specifies the start ECU and the start cause thereof from the start control frame and stores them in a nonvolatile memory.
摘要翻译：在网络系统中，每个ECU在启动时发送开始控制帧，并且当其在其操作停止期间从任何其它ECU接收到启动控制帧时开始。此外，每个ECU在其操作期间循环地发送停止控制帧，并且在从任何其他ECU接收到停止控制帧的同时，继续其操作，尽管能够停止其操作。在发送每个帧时，每个ECU将表示启动原因的原因信息或对帧的操作停止不能引起的原因。在停止网络时，监控装置从启动控制帧指定启动ECU及其启动原因并将其存储在非易失性存储器中。

摘要： A multiplex communication system includes a plurality of networks and a data relay unit. Each node included in each network resets a relay flag which is a predetermined bit of a data frame, when it sends the data frame to another node. If the data frame requires to be relayed, the data relay unit receives and relays the data frame. The data relay unit includes a relay flag check (RFC) section and a relay flag setting (RFS) section. The RFC section checks whether the relay flag of the data frame is set. If relay flag is set, the RFC section inhibits the data frame from being relayed. If the relay flag is not set, the RFC section allows the data frame to be relayed. The RFS section sets the relay flag of the data frame when the data frame is relayed.

摘要： A multiplex communication system includes a plurality of networks and a data relay unit. When an event occurs in a node belonging to one of the networks, the node (sender node) sends a wake-up frame before it sends an event frame. In response to the wake-up frame, the nodes belonging to the same network which includes the sender node are activated and the data relay unit sends a wake-up frame to the respective networks for activating the networks. When it is determined that each of the networks is activated, the data relay unit sends a network activation notifying (NAN) frame regarding the network to all the networks. The NAN frame regarding the network represents that the network is activated. The sender node sends the event frame in response to the NAN frame regarding the destination network of the event frame.

摘要： Code verification is executed with a surveillance target such as an engine ECU or an immobility ECU installed in a vehicle. Failure of the verification indicates that the corresponding ECU may have been replaced. No reply to the verification indicates that the corresponding ECU may have been removed. The failure or no reply causes bus interference through a bus interference generator. Specifically, the bus interference generator generates to circulate, over the bus, a signal interfering with a signal from the ECUs connected with a local area network to disable a plurality of driver/receiver ICs. This interference with the ECUs results in ceasing normal operations and reducing product value of the vehicle.

摘要： A plurality of electronic control units is continuously supplied with electric power to be capable of communication one another even when respective controlled devices are in inoperative condition. Each ECU transmits a sleep NG information along with its device ID when it not allowed to remain in the sleep mode. An abnormality detection unit connected to the ECUs through communication lines monitors the sleep NG information of each ECU to detect the ECU remaining activated for more than a wait period which is required for the ECU to shift to the sleep mode. The device ID of the ECU which is detected as remaining activated is stored in a memory so that any abnormal location may be specified by the stored device ID.

摘要： A multiplex communication system having a data repeater, which can prevent data from being lost so as to improve reliability of data communication, when a data repeater of a multiplex communication system repeats data. A multiplex communication system is made up of a plurality of communication groups including a plurality of communication lines and a data repeater. The data repeater is made up of receiving buffers, sending buffers, a data controller and a transfer-address table. The data controller selects multiplex communication lines through which the received data is to be repeated and transfers the received data thereto. The data controller has a priority-reset means for increasing a priority of a received data before being sent. The priority-reset means prioritizes a sending of the data from the data repeater, even if the data sent from the data repeater collides with the other data on the multiplex communication lines through which the received data is to be repeated. In this way, the priority-reset means prevents the data waiting for being sent in the data repeater from being lost by being overwritten with newly received data.

摘要： In a transceiver, a clock generator generates a second clock synchronized with a first clock. The second clock has a period corresponding to a duration of one bit of a digital signal. When first transmission data is supplied to the transceiver with being asynchronous to the second clock, a sampling timing generator detects start data of the first transmission data as a start timing, and generates sampling timings based on the first clock in response to the start timing. The sampling timings have intervals each of which is defined to correspond to the period of the second clock. The first sampling timing is spaced from the start timing. A sampling module samples, at each of the sampling timings, the first transmission data, thus generating second transmission data synchronized with the second clock.
