Abstract
A device includes a first interface unit connected to a first controller area network (CAN) bus, a second interface unit connected to a second CAN bus, and a control unit configured to identify, in a case where transmission of a CAN frame is started, a CAN bus detected to be in a dominant state first after end of arbitration from the first CAN bus or the second CAN bus, as a CAN bus to which a transmission source device of the CAN frame is connected.
Claims5
A device comprising:
- a first interface unit connected to a first controller area network (CAN) bus;
- a second interface unit connected to a second CAN bus;
- and
- a control unit configured to identify, in a case where transmission of a CAN frame is started, a CAN bus detected to be in a dominant state first after end of arbitration from the first CAN bus or the second CAN bus, as a CAN bus to which a transmission source device of the CAN frame is connected.
A method performed by a device connected to a first controller area network (CAN) bus and a second CAN bus, the method comprising:
- detecting start of transmission of a CAN frame;
- and
- identifying, in a case where transmission of the CAN frame is started, a CAN bus detected to be in a dominant state first after end of arbitration from the first CAN bus or the second CAN bus, as a CAN bus to which a transmission source device of the CAN frame is connected.
