Abstract

A system, apparatus, and method for retrofitting a vehicle are presented. The method relates to a vehicle with a factory-installed first apparatus which communicates with a factory-installed second apparatus through a vehicle data bus using a first message. The method includes electrically disconnecting the vehicle data bus between the first apparatus and the second apparatus and electrically connecting a retrofit apparatus to the vehicle data bus. The method further includes transmitting a second message from the retrofit apparatus to the first apparatus which is indistinguishable from the first message.

Claims

1. A method, comprising:

providing a vehicle having a factory-installed first apparatus (200) including a processor, programmed to communicate with a factory-installed second apparatus (218) through a vehicle data bus (212) with a first message having an identifier;

electrically disconnecting the vehicle data bus (212) between the factory-installed first apparatus (200) and the factory-installed second apparatus (218);

electrically connecting a retrofit apparatus (214) to the vehicle data bus (212); and

transmitting a second message from the retrofit apparatus (214) to the factory-installed first apparatus (200), the second message being indistinguishable from the first message.

2. The method as in claim 1, wherein the second message uses the identifier of the first message.

3. The method as in claim 1, further comprising receiving the first message in the retrofit apparatus (214).

4. The method as in claim 3, wherein the retrofit apparatus (214) re-transmits messages received on the vehicle data bus (212) to the factory-installed first apparatus (200).

5. The vehicle that has been retrofitted according to the method as in claim 1.

6. A vehicle, comprising:

a factory-installed first apparatus (200) including a first processor which is programmed to receive a first message on a vehicle data bus (212) from a factory-installed second apparatus (218); and

a retrofit apparatus (214) connected to the vehicle data bus (212) including a second processor programmed to transmit a second message which mimics the first message.

7. The vehicle as in claim 6, wherein the first message comprises a message identifier that has been assigned to the factory-installed second apparatus and wherein the second processor is programmed to transmit the second message with the same message identifier.

8. The vehicle as in claim 7, wherein the message identifier is an 11 bit or 29 bit CAN ID.

9. The vehicle as in claim 6, wherein the vehicle data bus (212) is a CAN network.

10. A vehicle, comprising:

a factory-installed first apparatus (200) including a first processor, programmed to receive a first message via a vehicle data bus (212) from a factory-installed second apparatus (218), the first message having a message identifier; and

a retrofit apparatus (214), operatively connected to the vehicle data bus (212), including a second processor programmed to send a second message having the same message identifier.

11. The vehicle as in claim 10, wherein the second message originating from the retrofit apparatus (214) is indistinguishable to the first apparatus (200) from the first message received from the second apparatus (218).

12. The vehicle as in claim 10, wherein the factory-installed first apparatus (200) responds to the second message originating from the retrofit apparatus (214) as if it were the first message received from the factory-installed second apparatus (218).

13. The vehicle as in claim 10, wherein the factory-installed first apparatus (200) is electrically disconnected from the vehicle data bus (212).

14. The vehicle as in claim 13, wherein the factory-installed first apparatus (200) communicates with the retrofit apparatus (214) through a second data bus.

15. The vehicle as in claim 14, wherein the retrofit apparatus (214) is a gateway through which the factory-installed first apparatus (200) transmits and/or receives messages from the vehicle data bus (212).

16. The vehicle as in claim 14, wherein the retrofit apparatus (214) selectively suppresses forwarding messages received from the factory-installed first apparatus (200) to the vehicle data bus.

17. The vehicle as in claim 10, wherein the factory-installed second apparatus is an object sensor capable of detecting objects in a frontal area of the vehicle.

18. The vehicle as in claim 10, wherein the factory-installed second apparatus is part of an automatic braking system.

19. The vehicle as in claim 10, wherein the factory-installed second apparatus is part of a parking aid system.
