Abstract

A remote programming system for engine control units of vehicles operates by coupling an onboard diagnostic interface device with an engine control unit of a vehicle, communicatively linking the interface device with a hand held device, communicatively linking the hand held device with a back end programming machine that is remotely located from the vehicle, communicating identifying information about the vehicle to the programming machine via the interface device, the hand held device, and the communication network(s), determining an action and programming information needed to program the engine control unit of the vehicle to accept a replacement key, sending the action and programming information from the programming machine to the hand held device via the communication network(s), and programming the engine control unit of the vehicle to accept the replacement key to activate the vehicle using or responsive to use of the action and programming information.

Claims

1. A method comprising:

coupling an onboard diagnostic interface device with an engine control unit of a vehicle that is programmed to accept a tangible first key for starting the vehicle;

communicatively linking the interface device with a mobile, hand held device;

communicatively linking, via one or more communication networks, the hand-held device with a back-end programming machine that is remotely located from the vehicle;

communicating identifying information about the vehicle to the programming machine via the interface device, the hand-held device, and the one or more communication networks by obtaining the identifying information from the engine control unit using the interface device, the identifying information including at least a vehicle identification number;

determining, at the programming machine, one or more actions and programming information needed to program the engine control unit of the vehicle to accept a tangible replacement key for starting the vehicle;

sending the one or more actions and programming information from the programming machine to the hand-held device via the one or more communication networks; and

programming the engine control unit of the vehicle to accept the replacement key for starting the vehicle using the one or more actions and programming information.

2. The method of claim 1, wherein the hand-held device is a mobile phone.

3. The method of claim 1, wherein, prior to programming the engine control unit of the vehicle to accept the replacement key to activate the vehicle, the engine control unit is restricted to only starting the vehicle when the first key is used.

4. The method of claim 1, wherein communicatively linking the interface device with the hand-held device includes one or more of:

establishing a wireless communication connection between the interface device and the hand-held device, or

connecting the interface device and the hand-held device with one or more wires or cables.

5. The method of claim 1, wherein communicatively linking the hand-held device with the programming machine includes establishing a wireless communication connection between the hand-held device and the one or more communication networks.

6. The method of claim 1, wherein determining the one or more actions and programming information needed to program the engine control unit of the vehicle to accept the replacement key includes using the identifying information about the vehicle to select the one or more actions and programming information from among different sets of actions and programming information that are associated with different vehicles.

7. The method of claim 1, wherein the one or more actions that are sent to the hand-held device include operator-implemented operations performed using the vehicle.

8. The method of claim 1, further comprising sending one or more of an indication that the engine control unit was successfully programmed to accept the replacement key or a location of the vehicle when the engine control unit was programmed to accept the replacement key from the engine control unit to the programming machine via the interface device, the hand-held device, and the one or more communication networks.

9. A method comprising:

coupling an onboard diagnostic interface device with an engine control unit of a vehicle that is programmed to accept a tangible first key for starting the vehicle;

communicatively linking, via one or more communication networks, the interface device with a back-end programming machine that is remotely located from the vehicle;

communicating identifying information about the vehicle to the programming machine via the interface device and the one or more communication networks, wherein communicating the identifying information about the vehicle to the programming machine via the interface device includes obtaining the identifying information from the engine control unit using the interface device, wherein the identifying information includes at least a vehicle identification number;

determining, at the programming machine, programming information needed to program the engine control unit of the vehicle to accept a tangible replacement key for starting the vehicle;

sending the programming information from the programming machine to the interface device via the one or more communication networks; and

programming the engine control unit of the vehicle to accept the replacement key for starting the vehicle using the one or more actions and programming information.

10. The method of claim 9, wherein, prior to programming the engine control unit of the vehicle to accept the replacement key to start the vehicle, the engine control unit is restricted to only starting the vehicle when the first key is used.

11. The method of claim 9, wherein communicatively linking the interface device with the programming machine includes establishing a wireless communication connection between the interface device and the one or more communication networks.

12. The method of claim 9, wherein determining the programming information needed to program the engine control unit of the vehicle to accept the replacement key includes using the identifying information about the vehicle to select the programming information from among different sets of programming information that are associated with different vehicles.

13. The method of claim 9, further comprising sending additional information from the engine control unit to the programming machine via the interface device and the one or more communication networks wherein the additional information includes one or more of an indication that the engine control unit was successfully programmed to accept the replacement key or a location of the vehicle when the engine control unit was programmed to accept the replacement key.

14. A system comprising:

a back-end programming machine including hardware circuitry and one or more processors configured to establish a communication connection with an engine control unit of a vehicle that is remotely located from the programming machine via an onboard diagnostic interface device and one or more communication networks, the engine control unit configured to start the vehicle responsive to a tangible first key being used to start the vehicle,

wherein the one or more processors are configured to receive identifying information about the vehicle from the engine control unit via the interface device and the one or more communication networks, the one or more processors configured to receive the identifying information about the vehicle by obtaining the identifying information from the engine control unit using the interface device, wherein the identifying information includes at least a vehicle identification number, the one or more processors also configured to determine programming information needed to program the engine control unit of the vehicle to accept a tangible replacement key to start the vehicle,

wherein the one or more processors are configured to send the programming information to the interface device via the one or more communication networks and to program the engine control unit of the vehicle to accept the replacement key to start the vehicle using the programming information.

15. The system of claim 14, wherein the interface device is an onboard diagnostic card.

16. The system of claim 14, wherein, prior to programming the engine control unit of the vehicle to accept the replacement key to start the vehicle, the engine control unit is restricted to only accepting the first key to start the vehicle.

17. The system of claim 14, wherein the one or more processors are configured for a communication connection with the interface device via a wireless communication connection between the interface device and the one or more communication networks.
