Abstract

The system includes a removable entertainment device that interfaces with a docking station. The removable entertainment device includes a controller that implements a software lock to disable the removable entertainment device, if it is improperly removed from the docking station. The docking station uses a challenge and response message to provide a secure methodology to control the unlocking of the removable entertainment device.

Claims

1. A system for preventing theft, the system comprising:

a removable entertainment device including a device controller, the removable entertainment device having a locked mode and an unlocked mode, the locked mode having reduced functionality from the unlocked mode;

a docking station configured to receive the removable entertainment device, the docking station including a docking station controller, wherein the device controller and the docking station controller are in electrical communication when the removable entertainment system is received by the docking station;

wherein the removable entertainment device is configured to transition from the locked mode to the unlocked mode when the removable entertainment system is received by the docking station.

2. The system according to claim 1, wherein the device controller is configured to send a challenge message to the docking station controller, and the docking station controller is configured to send a response message to the device controller, the device controller being configured to transition to the unlocked mode based on the response message.

3. The system according to claim 2, wherein the device controller passes a seed to the docking station controller, the docking station controller being configured to perform an algorithm on the seed to create a key and return the key to the device controller.

4. The system according to claim 3, wherein the device controller decodes the key using the algorithm to produce a authentication seed, the device controller being configured to transition to the unlocked state if the authentication seed matches the seed.

5. The system according to claim 2, wherein the device controller is configured to retry the challenge message if a response message is not received within a predefined time period.

6. The system according to claim 5, wherein the controller is configured to stop sending challenge messages after a predefined number of retries.

7. The system according to claim 1, wherein the removable entertainment device enters the locked mode based on the vehicle shutdown.

8. The system according to claim 7, wherein the removable entertainment device enters the locked mode if the removable entertainment device is received in the docking station during vehicle shutdown.

9. The system according to claim 1, wherein the docking station is configured to prevent release of the removable entertainment device when the vehicle is shutdown.

10. The system according to claim 9, wherein the docking station includes a latch configured to releasibly engage the removable entertainment system and the docking station is configured to disable the latch when the vehicle is shutdown.

11. A system for preventing theft, the system comprising:

a removable entertainment device including a device controller, the removable entertainment device having a locked mode and an unlocked mode, the locked mode having reduced functionality from the unlocked mode;

a docking station configured to receive the removable entertainment device, the docking station including a docking station controller, wherein the device controller and the docking station controller are in electrical communication when the removable entertainment system is received by the docking station;

the removable entertainment device is configured to transition from the locked mode to the unlocked mode when the removable entertainment system is received by the docking station;

the removable entertainment device enters the locked mode based on the vehicle shutdown; and

the docking station is configured to prevent release of the removable entertainment device when the vehicle is shutdown.

12. The system according to claim 11, wherein the device controller is configured to send a challenge message to the docking station controller, and the docking station controller is configured to send a response message to the device controller, the device controller being configured to transition to the unlocked mode based on the response message.

13. The system according to claim 12, wherein the device controller passes a seed to the docking station controller, the docking station controller being configured to perform an algorithm on the seed to create a key and return the key to the device controller.

14. The system according to claim 13, wherein the device controller decodes the key using the algorithm to produce a authentication seed, the device controller being configured to transition to the unlocked state if the authentication seed matches the seed.

15. The system according to claim 12, wherein the device controller is configured to retry the challenge message if a response message is not received within a predefined time period.

16. The system according to claim 15, wherein the controller is configured to stop sending challenge messages after a predefined number of retries.

17. The system according to claim 16, wherein the removable entertainment device enters the locked mode if the removable entertainment device is received in the docking station during vehicle shutdown.

18. The system according to claim 17, wherein the docking station includes a latch configured to releasibly engage the removable entertainment system and the docking station is configured to disable the latch when the vehicle is shutdown.
