Abstract: A replay device includes: multiple transceiver units that transmits and receives a communication frame, each transceiver unit including a register in which at least data indicating a set-up content relating to an operation of a respective transceiver unit is written; a register access unit that is connected with each transceiver unit through an interface; and a control unit that transmits a control message to the register access unit. The control message includes access target information for designating one or more access target transceiver units, and access content information indicating an access content to a register of each access target transceiver unit. The register access unit sets the one or more target transceiver units designated by the access target information, and perform an access to the register of each access target transceiver unit according to the access content.

Abstract: A repeater for transferring same-destination frames that are addressed to a destination Electronic Control Unit (ECU) efficiently by receiving the frames from respectively different ports, includes: four ports; and a switcher, wherein the first and second ports respectively originating a communication path to an individual ECU, and the third and fourth ports respectively connected to an individual ECU that is different from the one connected the first and second ports, and when the same-destination frames are received by the third and fourth ports of the repeater at the same time, the switcher distributes the same-destination frames among the first and second ports to be transferred via two, i.e., different, communication paths toward one, i.e., same, destination ECU.

Abstract: A relay apparatus includes multiple ports, a switch section, multiple physical layer (PHY) sections, a first control section, and a second control section. Each of the ports transmits or receives a frame. The first control section switches a subject PHY section, which is one of the multiple PHY sections and corresponds to the port receiving the frame, from an off state to an on state when the switch section is in an off state and each of the multiple PHY sections is in an off state. The second control section switches the switch section from the off state to an on state when (i) the subject PHY section is switched from the off state to the on state, (ii) the switch section is in the off state, and (iii) the multiple PHY sections except for the subject PHY section are in the off states.

Abstract: A charge-discharge controller includes a resetter for executing a SOC reset charging and a timing calculator for executing a timing calculation process that calculates an execution timing of the SOC reset charging by the resetter. The timing calculator calculates a profit reduction amount by an execution of the SOC reset charging for each of a plurality of time ranges, and sets the execution timing of the SOC reset charging in one or more time ranges to minimize the profit reduction amount, in consideration of an economy of charging of battery besides SOC.

Abstract: A repeater efficiently transfers frames addressed to the same destination address when the frames are received at the same time by a plurality of ports, by performing a distribute-transfer process, when a difference between a size of each of the frames received by a normal port and an average size of those frames is within a preset range for all the frames, or an actual-measured communication speed of each of two ring ports is greater than a threshold. The distribute-transfer process distributes and transmits the frames to two communication paths from the two ring ports after receiving the frames at the two normal ports. The highest actual-measured communication speed of a ring port among other ring ports of the repeaters is considered as a communication efficiency parameter for selecting a broadest communication path for transmitting the frame. The frame(s) having the highest communication speed is/are distributed to the ring port connected to the broadest path.
