Abstract

Methods and systems are provided for providing fault notifications for vehicles. A notification unit is configured to provide a notification when a fault is detected for a vehicle. A processor is coupled to the notification unit, and is configured to provide instructions to the notification unit to provide the notification when the fault is detected, and restrict operation of the vehicle, when the fault is detected, until an action is taken in response to the notification.

Claims

1. A method comprising:

providing a notification when a latent fault is detected for a vehicle;

restricting operation of the vehicle, via a processor, in a manner that prevents a driver from driving the vehicle, when the latent fault is detected, until an action is taken in response to the notification that acknowledges or corrects the latent fault; and

allowing the driver to operate the vehicle after the action is taken that acknowledges or corrects the latent fault.

2. The method of claim 1, wherein:

the step of providing the notification comprises providing the notification when a user attempts to start an engine of the vehicle; and

the step of restricting operation of the vehicle comprises preventing the engine from starting until the action is taken that acknowledges or corrects the latent fault.

3. The method of claim 1, wherein a request to change a transmission mode of the vehicle out of a park mode is denied until the action is taken that acknowledges or corrects the latent fault.

4. The method of claim 1, wherein:

the step of providing the notification comprises providing the notification at the beginning of each ignition cycle once the latent fault is detected; and

the step of restricting operation of the vehicle comprises restricting operation of the vehicle, after the notification has been provided for a predetermined number of ignition cycles, until the action is taken that acknowledges or corrects the latent fault.

5. The method of claim 1, wherein the action comprises an acknowledgement by the driver that the driver has reviewed the notification regarding the latent fault.

6. The method of claim 5, wherein the action comprises the driver engaging a switch on a dashboard display for the vehicle acknowledging that the driver of the vehicle has reviewed the notification regarding the latent fault.

7. The method of claim 5, further comprising:

providing a countdown timer along with the notification, the countdown comprising a minimum amount of time for which the notification must be displayed before dismissal may occur;

wherein the step of restricting operation of the vehicle comprises preventing an engine of the vehicle from starting until both the countdown timer has expired and the acknowledgement by the driver has been made.

8. The method of claim 1, wherein the action comprises an acknowledgement by the driver that the latent fault is present.

9. The method of claim 8, wherein the action comprises entering a code serving as evidence that the latent fault has been corrected by a service center.

10. A system comprising:

a notification unit configured to provide a notification when a latent fault is detected for a vehicle; and

a processor coupled to the notification unit, the processor configured to;

provide instructions to the notification unit to provide the notification when the latent fault is detected;

restrict operation of the vehicle, when the fault is detected, in a manner that prevents a driver from driving the vehicle, until an action is taken in response to the notification, and

allow the driver to operate the vehicle after the action is taken that acknowledges or corrects the latent fault.

11. The system of claim 10, wherein the processor is configured to:

instruct the notification unit to provide the notification when a user attempts to start an engine of the vehicle; and

prevent the engine from starting until the action is taken that acknowledges or corrects the latent fault.

12. The system of claim 10, wherein the processor is configured to provide instructions to deny a request to change a transmission mode of the vehicle out of a park mode until the action is taken that acknowledges or corrects the latent fault.

13. The system of claim 10, wherein the processor is configured to:

instruct the notification unit to provide the notification at the beginning of each ignition cycle once the latent fault is detected; and

restrict operation of the vehicle, after the notification has been provided for a predetermined number of ignition cycles, until the action is taken that acknowledges or corrects the latent fault.

14. The system of claim 10, wherein the action comprises an acknowledgement by the driver that the driver has reviewed the notification regarding the latent fault.

15. The system of claim 14, wherein the action comprises the driver engaging a switch on a dashboard display for the vehicle acknowledging that the driver of the vehicle has reviewed the notification regarding the latent fault.

16. The system of claim 14, wherein the processor is configured to:

instruct the notification unit to provide a countdown timer along with the notification, the countdown comprising a minimum amount of time for which the notification must be displayed before dismissal may occur;

and prevent an engine of the vehicle from starting until both the countdown timer has expired and the acknowledgement by the driver has been made.

17. The system of claim 10, wherein the action comprises an acknowledgement by the driver that the latent fault is present.

18. The system of claim 17, wherein the action comprises entering a code serving as evidence that the latent fault has been corrected by a service center.

19. A vehicle comprising:

a drive system;

a notification unit configured to provide a notification when a latent fault is detected for the vehicle; and

a processor coupled to the notification unit, the processor configured to;

provide instructions to the notification unit to provide the notification when the latent fault is detected;

restrict operation of the drive system, in a manner that prevents a driver from driving the vehicle, when the fault is detected, until an action is taken in response to the notification; and

allow the driver to operate the vehicle after the action is taken that acknowledges or corrects the latent fault.

20. The vehicle of claim 19, wherein:

the drive system comprises an engine; and

the processor is configured to;

instruct the notification unit to provide the notification when a user attempts to start the engine; and

prevent the engine from starting until the action is taken that acknowledges or corrects the latent fault.
