Abstract

In an arrangement for reprogramming at least two control devices connected to one another via a data bus, each of the at least two control devices includes a reprogramming module for effecting reprogramming of the each of the at least two control devices with new program data according to a first reprogramming protocol. A conversion module connected to the data bus receives the new program data using a second reprogramming protocol, and transmits the new program data onto the data bus using the first reprogramming protocol.

Claims

1. An arrangement for reprogramming control devices connected to a data bus, comprising:

a data bus;

at least two control devices connected to one another by the data bus, wherein each of the at least two control devices includes a reprogramming module configured for effecting reprogramming of the each of the at least two control devices with new program data in accordance with a first reprogramming protocol; and

a conversion module connected to the data bus and configured to receive new program data using a second reprogramming protocol and transmit the new program data onto the data bus using the first reprogramming protocol.

2. The arrangement of claim 1, wherein the conversion module is further configured to receive further data using the first reprogramming protocol and transmit the further data onto the data bus using the second reprogramming protocol.

3. The arrangement of claim 1, wherein the conversion module is a component of one of the at least two control devices.

4. The arrangement of claim 1, wherein the conversion module is further configured to receive the new program data using a third reprogramming protocol and transmit the new program data onto the data bus using the first reprogramming protocol.

5. The arrangement of claim 4, wherein the conversion module is configured to detect automatically whether the new program data are transmitted using the second preprogramming protocol or the third reprogramming protocol.

6. The arrangement of claim 1, wherein the conversion module receives the new program data from the data bus.

7. The arrangement of claim 1, wherein the arrangement is located in a motor vehicle.

8. A conversion module connectable to a data bus and configured to receive new program data using a second preprogramming protocol and transmit the new program data onto the data bus using a first reprogramming protocol, the new program data including data for reprogramming at least two control devices connected to one another by the data bus.

9. A method for reprogramming at least two control devices connected to one another by a data bus, wherein each of the at least two control devices includes a reprogramming module for effecting reprogramming of the each of the at least two control devices with new program data according to a first reprogramming protocol, the method comprising:

receiving new program data using a second preprogramming protocol;

converting the received new program data to produce converted new program data using the first reprogramming protocol; and

transmitting the converted new program data onto the data bus.
