A secondary control unit for a vehicle with a primary control unit and a data transmission path

A secondary control unit for a vehicle, comprising:

• a primary control unit and a data transmission path, wherein the primary control unit is configured to provide first payloads via the data transmission path under a first sender identifier uniquely referring to the primary control unit;
• wherein the secondary control unit is configured to perform the following:
• providing second payloads, under a second sender identifier uniquely referring to the secondary control unit, via the data transmission path;
• verifying a condition;
• and
• providing, if the condition is present, substitute payloads under the first sender identifier via the data transmission path, wherein the substitute payloads are the first payloads or payloads related thereto.

A data communication network for a vehicle, comprising:

• at least one bus;
• and
• a primary control unit and a data transmission path, and configured to provide first payloads on the at least one bus under a first sender identifier uniquely referring to the primary control unit;
• and
• a secondary control unit configured to perform the following:
• providing second payloads, under a second sender identifier uniquely referring to the secondary control unit, via the data transmission path;
• verifying a condition;
• and
• providing, if the condition is present, substitute payloads under the first sender identifier via the data transmission path, wherein the substitute payloads are the first payloads or payloads related thereto, wherein the data transmission path includes at least one bus.

A commercial vehicle, comprising:

• a data communication network for a vehicle, including:
• at least one bus;
• and
• a primary control unit and a data transmission path, and configured to provide first payloads on the at least one bus under a first sender identifier uniquely referring to the primary control unit;
• and
• a secondary control unit configured to perform the following:
• providing second payloads, under a second sender identifier uniquely referring to the secondary control unit, via the data transmission path;
• verifying a condition;
• and
• providing, if the condition is present, substitute payloads under the first sender identifier via the data transmission path, wherein the substitute payloads are the first payloads or payloads related thereto, wherein the data transmission path includes at least one bus.

A non-transitory computer readable storage medium having a computer program, which is executable by a processor, comprising:

• a program code arrangement having program code for redundantly providing first payloads in a vehicle, by performing the following:
• determining a condition, wherein the vehicle includes a data transmission path, a primary control unit configured to provide the first payloads under a first sender identifier uniquely referring to the primary control unit via the data transmission path, and a secondary control unit configured to provide second payloads under a second sender identifier uniquely referring to the secondary control unit via the data transmission path;
• and
• providing, if the condition is present, and by the secondary control unit, substitute payloads under the first sender identifier via the data transmission path, wherein the substitute payloads are the first payloads or payloads related thereto.
