DEVICE AND METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18456641 titled 'DEVICE AND METHOD

Simplified Explanation

The abstract describes a device with two interface units connected to separate CAN buses, and a control unit that identifies the dominant state of a CAN bus after arbitration to determine the transmission source device of a CAN frame.

  • The device has a first interface unit connected to a first CAN bus and a second interface unit connected to a second CAN bus.
  • The control unit is able to detect which CAN bus is in a dominant state after arbitration, indicating the transmission source device of a CAN frame.
  • This technology helps in identifying the correct source device for a CAN frame transmission.

Potential Applications

  • Automotive industry for vehicle communication systems.
  • Industrial automation for controlling machinery and equipment.

Problems Solved

  • Ensures accurate identification of the transmission source device in a CAN network.
  • Helps in preventing data collisions and ensuring efficient communication.

Benefits

  • Improved reliability and efficiency in CAN bus communication.
  • Enhanced performance of devices connected to the CAN network.


Original Abstract Submitted

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.
