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.
