Abstract: Provided is a vehicle-mounted relay device that can suppress failures in reading/writing of data due to electric power shortage. The vehicle-mounted relay device determines whether or not reading/writing of data is possible based on the required amount of stored power in the electric power storage device and the remaining amount of stored power in the electric power storage device needed to read/write the data. If the remaining amount of stored power is equal to or greater than the required amount of stored power, there is no risk that the remaining amount of stored power in the electric power storage device may run short before the reading/writing of the data ends. Accordingly, if it is determined that reading/writing of the data is possible, the vehicle-mounted relay device causes an ECU, which is a vehicle-mounted control device, to start reading/writing the data.

Abstract: It is an object of the present disclosure to reduce the number of constituent components and accurately detect a current. A current detection circuit detects a current flowing through a DC/DC converter. A first output unit applies, to a third signal path, a voltage that corresponds to an output from a detection sensor, which has detected a larger current, out of a first sensor and a second sensor. Furthermore, the first output unit applies, to the third signal path, a voltage obtained by reflecting a voltage drop at the transistor or the transistor that is connected to the detection sensor, in the voltage output from the detection sensor. A second output unit applies, to a fourth signal path, a voltage obtained by reflecting a voltage drop that occurs between a base and an emitter of a transistor, in the voltage applied to the third signal path.

Abstract: Provided is a vehicle-mounted relay device, a vehicle-mounted communication system, and a relay program configured to prevent an unauthorized message from being relayed between networks. A vehicle-mounted relay device includes a plurality of communication units to which a plurality of CAN buses are connected and determines whether a message transmitted by any ECU connected to the CAN buses are authorized.

The vehicle-mounted relay device prohibits further relaying of a message that has the same CAN-ID as the CAN-ID contained in the message determined to be unauthorized. Concurrently, the vehicle-mounted relay device gives, to the other communication lines connected to a communication unit, a notification that relay of the message is prohibited.
