Controller area network (can) device, can system, and method for the can device

A Controller Area Network (CAN) device comprising:

• a data (RD) interface,
• a processing unit, and
• a bus interface for coupling to a CAN bus,
• wherein the CAN device is configured to receive first data via the RD interface,
• wherein the processing unit is configured to create a frame series of CAN frames based on the first data such that the frame series comprises a start CAN frame and at least one follower CAN frame,
• wherein the processing unit is configured to distribute the first data among the CAN frames of the frame series,
• wherein the processing unit is configured to create the start CAN frame such that the start CAN frame comprises an identifier that represents a start priority value within a predefined first value range,
• wherein the processing unit is configured to create each follower CAN frame such that each follower CAN frame comprises a respectively associated identifier that represents a follower priority value within a predefined second value range,
• wherein the second value range is less than the first value range, and
• wherein the CAN device is configured to transmit the CAN frames of the frame series via the RD interface such that the at least one follower CAN frame follows the start CAN frame.

A Controller Area Network (CAN) system comprising:

• a CAN bus, and
• a plurality of CAN devices,
• wherein each CAN device is coupled to the CAN bus, and
• wherein each CAN, device comprising a data (RD) interface, a processing unit, and a bus interface for coupling to a CAN bus,
• wherein each CAN device is configured to receive first data via the RD interface,
• wherein the processing unit of each CAN device is configured to create a frame series of CAN frames based on the first data such that the frame series comprises a start CAN frame and at least one follower CAN frame,
• wherein the processing unit of each CAN device is configured to distribute the first data among the CAN frames of the frame series,
• wherein the processing unit of each CAN device is configured to create the start CAN frame such that the start CAN frame comprises an identifier that represents a start priority value within a predefined first value range,
• wherein the processing unit of each CAN device is configured to create each follower CAN frame such that each follower CAN frame comprises a respectively associated identifier that represents a follower priority value within a predefined second value range,
• wherein the second value range is less than the first value range, and
• wherein each CAN device is configured to transmit the CAN frames of the frame series via the CAN interface such that the at least one follower CAN frame follows the start CAN frame.

A method for a Controller Area Network (CAN) device, wherein the CAN device comprises a data (RD) interface, a processing unit, and a bus interface for coupling to a CAN bus, the method comprising the steps of:

• a) receiving first data via the RD interface;
• b) the processing unit creating a frame series of CAN frames based on the first data via the processing unit, such that the frame series comprises a start CAN frame and a follower CAN frame, wherein the start CAN frame comprises an identifier that represents a start priority value within a first predefined value range, and wherein each follower CAN frame comprises a respectively associated identifier that represents a follower priority value within a second predefined value range, and wherein the second value range is less than the first value range;
• wherein the processing unit distributes the first data among the CAN frames of the frame series, and
• c) the CAN device transmitting the CAN frames of the frame series via the CAN interface such that the at least one follower CAN frame follows the start CAN frame.
