  • Patent number: 9588579
    Abstract: An electronic control unit includes a microcomputer, a monitoring unit, a clock-generating oscillator circuit, a first power circuit supplying power to the microcomputer, and a second power circuit supplying power to the monitor microcomputer. The first power circuit includes a first switching power source including a first transistor and a first series power source including a second transistor. The second power circuit includes a second switching power source including a third transistor and a second series power source including a fourth transistor. Further, the ECU includes a power control circuit controlling each of the transistors and an oscillation stop detection circuit.

  • Publication number: 20160117214
    Abstract: A controller includes a microcomputer that operates in a normal mode or in a low power mode and communicates with an external device, a monitor circuit that monitors an operation state of the microcomputer based on a monitor signal output from the microcomputer, and a start circuit that controls a drive of the monitor circuit. Communication signals exchanged between the microcomputer and the external device include a dominant state and a recessive state, and the start circuit monitors the communication signals. When the communication signals in the low power mode of the microcomputer include the dominant state, the start circuit puts the monitor circuit in a monitoring state. When no monitor signal is input from the microcomputer to the monitor circuit that is operating in the monitoring state, the monitor circuit determines that an abnormality has occurred in the microcomputer.

  • Publication number: 20160098071
    Abstract: An electronic control unit includes a microcomputer and a power circuit that supplies an electric power to the microcomputer. The microcomputer and the power circuit respectively operate in a normal operation mode and in a low power operation mode that consumes less power than the normal operation mode. The electronic control unit further includes a mode switcher for switching the operation modes of the microcomputer and the power circuit according to an input signal from an external device. When a mode switch signal for switching the operation mode of both devices to the normal operation mode, the mode switcher first switches the power circuit to the normal operation mode and subsequently switches the microcomputer to the normal operation mode, which prevents a reset operation of the microcomputer without using a large capacity capacitor.

  • Patent number: 8477612
    Abstract: An object of the invention is to provide a charging processing device and a charging processing method capable of performing an appropriate charging process even when a connectionless protocol, such as UDP, is used. Gateway units 101 and 106 transmit data transmitted between a mobile apparatus 300 and a server 400 to the mobile apparatus 300 or the server 400 as a transmission destination, and a charging processing unit 102 performs a charging process according to the amount of data transmitted by the gateway units 101 and 106. A detecting unit 103 detects whether response data is transmitted from the transmission destination. When the timer value of the time for which communication is not performed is more than a predetermined time and the detecting unit 103 does not detect the response data from the transmission destination, the control unit 104 may control the gateway unit 101 or 106 to stop the transmission process and control the charging processing unit 102 to stop the charging process.

  • Patent number: 8135284
    Abstract: In a method and device which can quickly detect a fiber misconnection without setting an expected value, a node identifier of source node and an identifier of an interface for inputting/outputting a signal are set in a predetermined first field of a header to be transmitted to a destination node, and when both identifiers set in the first field are received from the destination node, both identifiers are set in a predetermined second field of the header to be transmitted and stored with the first field. When the identifiers set in the first and second fields are received and the identifiers of the second field among the identifiers are consistent with the identifiers of the first field stored at the second step (means), a connection is determined to be correct.
