  • Patent number: 10460896
    Abstract: A relay control device is provided configured to reduce the amount of power supplied to a coil in an electromagnetic relay. The relay control device includes a control unit for generating and outputting a PFM signal to control the voltage-drop DC/DC converter unit, a filter unit allowing passage of the PFM signal, and a circuit unit controlling the operation of the voltage-drop DC/DC converter unit in accordance with the output signal of the filter unit. If the filter unit does not allow passage of the PFM signal, the circuit unit prevents the voltage-drop DC/DC converter unit from dropping the voltage, and performs control so as to output the power supply voltage to a coil in the electromagnetic relay. If the filter unit prevents the PFM signal from passing, a current path from a power supply potential to a ground potential within a circuit unit is cut off by transistors.

  • Patent number: 10432421
    Abstract: Provided are a communication control device and a communication system capable of detecting message transmission in the case where an invalid device transmits a message to a common communication line. A monitoring device decides a reference time point t0 for periodical message transmission by an ECU, decides multiple scheduled transmission time points t1, t2, . . . obtained by adding a period corresponding to an integer multiple of a transmission cycle T of a message to the reference time point t0, and decides that a predetermined period including each of the scheduled transmission time points is a permission period for message transmission. The monitoring device determines whether or not a detected message on a CAN bus has been transmitted during the permission period. If determined that transmission of an invalid message is not permitted, the monitoring device performs processing of causing the ECU which receives the message to discard the message.
