    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： 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： 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 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： 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： 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.

    摘要： A LIN receiver includes a voltage divider that divides an input voltage and outputs the divided voltage, and a peak hold circuit that outputs a peak voltage of the input voltage. The LIN receiver is configured to generate a threshold voltage to be used for determining a voltage signal of a communication bus. The threshold voltage is generated from a voltage signal of the communication bus such that the peak value of the voltage signal (i.e., equivalent to a battery voltage) is held by the peak hold circuit and divided by the voltage divider. Although the communication bus is connected to an on-vehicle battery of which voltage varies with time, by using the voltage signal of the communication bus, a 5V system ECU can generate a threshold voltage which varies responding to the variation of the battery voltage. Hence, the voltage signal can be determined correctly as either high or low level.

    摘要： A ringing suppression circuit for a communication circuit that performs communication through a transmission line includes a high side switch connected between a high potential reference point and a high side line of the transmission line, a low side switch connected between a low potential reference point and a low side line of the transmission line, and a ringing suppression section. The ringing suppression section turns on the high side switch based on a difference between a potential of the high side line and a potential applied to a control terminal of the high side switch. The ringing suppression section turns on the low side switch based on a difference between a potential of the low side line and potential applied to a control terminal of the low side switch.
