Abstract

Systems and methods are provided for validating a vehicle component. The system includes a vehicle electronic control unit (ECU) in electronic communication with a power unit via a communications bus. The vehicle ECU is configured to detect an electronic connection between the vehicle ECU and the power unit and transmit a power start up signal to the power unit when the power unit is authenticated to start up. The power unit is authenticated to start up when a power unit start-up program passcode stored in a memory of the vehicle ECU matches a predetermined ECU passcode. The vehicle ECU is configured to erase the power unit start-up program passcode from the memory when the power unit is disconnected from the communications bus. The vehicle ECU is configured to re-authenticate the power unit to start up when a new power unit start-up program passcode is stored in the memory that matches another predetermined ECU passcode.

Claims

1. A method for validating a vehicle component, the method comprising:

detecting an electronic connection between a vehicle electronic control unit (ECU) and a vehicle power unit over a communications bus;

comparing a vehicle power unit start-up program passcode stored in a memory of the vehicle ECU to at least one predetermined ECU passcode;

authenticating the vehicle power unit to start-up with the vehicle ECU when the vehicle power unit start-up program passcode matches the ECU passcode;

transmitting a power up signal from the vehicle ECU to the vehicle power unit when the vehicle power unit is authenticated;

monitoring the communications bus for when the vehicle power unit is disconnected from the communications bus;

erasing the vehicle power unit start-up program passcode from the memory of the vehicle ECU when the vehicle power unit is disconnected from the bus;

erasing the predetermined ECU passcode corresponding to the vehicle power unit start-up program passcode when the vehicle power unit is disconnected from the communications bus;

storing a new vehicle power unit start-up program passcode in the memory; and

re-authenticating the vehicle power unit with the vehicle ECU when the new vehicle power unit start-up program passcode matches another of the predetermined ECU passcodes.

2. The method of claim 1, wherein the new vehicle power unit start-up program passcode is based on at least one of a vehicle identification number, an airframe identification number, an ECU identification number, a vehicle power unit identification number, or a combination thereof.

3. The method of claim 1, wherein the vehicle power unit start-up program passcode is erased from the memory when a new engine component is connected to the communications bus.

4. The method of claim 1, wherein the new vehicle power unit start-up program passcode is a time limit based passcode.

5. The method of claim 1, wherein the new vehicle power unit start-up program passcode is a stop/start cycle passcode with a predetermined number of start/stop cycles of the vehicle power unit.

6. The method of claim 1, further comprising

retrieving the new vehicle power unit start-up program passcode from a remote server;

and

entering the new vehicle power unit start-up program passcode into the memory.

7. The method of claim 1, further comprising storing an alert in the memory when the new vehicle power unit start-up program passcode does not match any of the predetermined ECU passcodes.

8. The method of claim 1, further comprising alerting a remote server when the new vehicle power unit start-up program passcode does not match any of the predetermined ECU passcodes.

9. The method of claim 1, further comprising disabling the vehicle power unit when the new vehicle power unit start-up program passcode does not match any of the predetermined ECU passcodes.

10. A system for validating a vehicle component, the system comprising:

a communications bus;

a vehicle power unit in electronic connection with the communication bus; and

a vehicle electronic control unit (ECU) having a processor and a memory, the vehicle ECU in electronic connection with the communication bus, the vehicle ECU configured to detect an electronic connection between the vehicle ECU and the vehicle power unit and transmit a power up signal to the vehicle power unit when the vehicle power unit is authenticated to start up,

wherein the vehicle power unit is authenticated to start up when a vehicle power unit start-up program passcode stored in the memory of the vehicle ECU matches at least one predetermined ECU passcode,

wherein the vehicle ECU is configured to erase the vehicle power unit start-up program passcode from the memory of the vehicle ECU when the vehicle power unit is disconnected from the communications bus,

wherein the vehicle ECU is configured to erase the predetermined ECU passcode corresponding to the vehicle power unit start-up program passcode when the vehicle power unit is disconnected from the communications bus, and

wherein the vehicle ECU is configured to re-authenticate the vehicle power unit to start up when a new vehicle power unit start-up program passcode is stored in the memory that matches another of the predetermined ECU passcodes.

11. The system of claim 10, wherein the new vehicle power unit start-up program passcode is based on at least one of a vehicle identification number, an airframe identification number, an ECU identification number, a vehicle power unit identification number, or a combination thereof.

12. The system of claim 10, wherein the vehicle power unit start-up program passcode is erased from the memory when a new engine component is connected to the communications bus.

13. The system of claim 10, wherein the new vehicle power unit start-up program passcode is a time limit based passcode.

14. The system of claim 10, wherein the new vehicle power unit start-up program passcode is a stop/start cycle passcode with a predetermined number of start/stop cycles of the vehicle power unit.

15. The system of claim 10, further comprising a remote server configured to store the new vehicle power unit start-up program passcode.

16. The system of claim 10, wherein the vehicle ECU is configured to store an alert in the memory when the new vehicle power unit start-up program passcode does not match any of the predetermined ECU passcodes.

17. The system of claim 10, further comprising a remote server wherein the vehicle ECU is configured to alert the remote server when the new vehicle power unit start-up program passcode does not match any of the predetermined ECU passcodes.

18. The system of claim 10, wherein the vehicle ECU is configured to disable the vehicle power unit when the new vehicle power unit start-up program passcode does not match any of the predetermined ECU passcodes.
