FAULT TOLERANT DISPLAY
First Claim
Patent Images
1. A fault tolerant display system for a vehicle comprising:
- a fault tolerant module that;
receives streaming video from a video camera;
merges the streaming video with overlays from an application processor to create an overlaid streaming video; and
displays the overlaid streaming video on a shared display area, the shared display area capable of displaying infotainment information from the application processor and capable of displaying the overlaid streaming video;
a policy enforcing module that;
detects failure of the application processor; and
in response to detecting failure of the application processor, switches to displaying on the shared display area in the cabin of the vehicle, the streaming video from the video camera and at least one overlay generated by the fault tolerant module, the streaming video from the video camera and the at least one overlay generated by the fault tolerant module displaying essentially simultaneously on the shared display area.

Abstract
A fault tolerant display displays safety information on a display shared with an infotainment system even if the processor or software of the infotainment system is unresponsive. The display can be a streaming video from a rear view camera mounted on a vehicle. The safety displayed can be triggered by placing the vehicle in reverse. Failure of the infotainment software and/or processor can be detected by a policy enforcing module that switches to a backup display that streams video directly from the camera in the event of failure of the infotainment processor.

19. A method comprising:
-
receiving streaming video from a video camera of a vehicle; merging the streaming video with overlays from an application processor to create an overlaid streaming video by a fault tolerant module; and displaying the overlaid streaming video on a shared display area in a cabin of the vehicle, the shared display area capable of displaying infotainment information from an infotainment system and capable of displaying the overlaid streaming video; monitoring an application processor to detect failure of the application processor; and in response to detecting failure of the application processor, switching to displaying on the shared display area in the cabin of the vehicle, the streaming video from the video camera and at least one overlay generated by the fault tolerant module, the streaming video from the video camera and the at least one overlay generated by the fault tolerant module displaying essentially simultaneously on the shared display area.

20. A computer-readable storage medium comprising computer-executable instructions which when executed cause at least one processor of a computing device to:
-
receive streaming video from a video camera; merge the streaming video with overlays from an application processor to create an overlaid streaming video; and display the overlaid streaming video on a shared display area in a cabin of the vehicle, the shared display area capable of displaying infotainment information from the application processor and capable of displaying the overlaid streaming video; monitor the application processor to detect failure of the application processor; and in response to detecting failure of the application processor, switch to displaying on the shared display area in the cabin of the vehicle, the streaming video from the video camera and at least one overlay generated by the fault tolerant module, the streaming video from the video camera and the at least one overlay generated by the fault tolerant module displaying essentially simultaneously on the shared display area.
