Abstract

A computing device for a vehicle comprising: a display screen; a central processing unit configured to run an operating system and at least one application operable to output an internal video signal adapted to be displayed on the display screen; a camera interface configured to receive a video input from one or more external cameras and to output corresponding external video signals for display on the display screen; a multiplexing unit configured for receiving the internal video signal and the one or more external video signals, the multiplexing unit comprising a display output coupled to the display screen and being configured for selectively forwarding one of the internal video signal and the one or more external video signals on the display output towards the display screen; and a controller unit configured for controlling the selective forwarding of the multiplexing unit based on controller input received by the controller unit.

Claims

1. A computing device for a vehicle comprising:

(a) a display screen;

(b) a central processing unit configured to run an operating system and at least one application, wherein the at least one application is operable to output an internal video signal adapted to be displayed on the display screen;

(c) a camera interface configured to receive a video input from one or more external cameras and to output one or more corresponding external video signals for display on the display screen;

(d) a multiplexing unit configured for receiving the internal video signal and the one or more external video signals, the multiplexing unit comprising a display output coupled to the display screen and being configured for selectively forwarding one of the internal video signal and the one or more external video signals on the display output towards the display screen; and

(e) a controller unit configured for controlling the selective forwarding of the multiplexing unit based on controller input received by the controller unit.

2. The computing device according to claim 1, wherein the controller unit comprises an operating system-less controller.

3. The computing device according to claim 1, wherein the multiplexing unit thereby enables the display screen to alternatively display one of the internal video signal and the external video signals.

4. The computing device according to claim 1, wherein the camera interface is configured to receive an analog video input and to convert the analog video input into a digital external video signal.

5. The computing device according to claim 1, wherein the multiplexing unit is further configured to convert the one or more output external video signals into a format adapted to be displayed on the display screen.

6. The computing device according to claim 1, wherein the at least one application is a driving assistance application.

7. The computing device according to claim 1, wherein the at least one application is a fleet management application.

8. The computing device according to claim 1, further comprising:

(a) an internal speaker;

(b) an audio interface configured to receive an audio input from at least one external microphone and to output an external audio signal,

wherein;

the at least one application is further operable to output an internal audio signal adapted to be interpreted by the internal speaker; and

the multiplexing unit is further configured for receiving the internal audio signal and the external audio signal, the multiplexing unit further comprising an audio output coupled to the internal speaker and being configured for selectively forwarding one of the internal audio signal and the external audio signal on the audio output towards the internal speaker.

9. The computing device according to claim 8, wherein the multiplexing unit thereby enables the internal speaker to alternatively play the internal audio signal or the external audio signal and wherein an audio path thereby bypasses the central processing unit

10. The computing device according to claim 8, wherein the audio interface is further configured to amplify the received audio input.

11. The computing device according to claim 8, wherein the at least one application manages another microphone.

12. The computing device according to claim 8, further comprising an additional speaker, wherein the multiplexing unit comprises an additional audio output coupled to the additional speaker and the multiplexing unit is further configured for selectively forwarding one of the internal audio signal and the external audio signal on the additional audio output towards the additional speaker.

13. The computing device according to claim 8, wherein the multiplexing unit comprises an audio module dedicated to multiplexing of audio signals and a video module dedicated to multiplexing of video signals.

14. The computing device according to claim 1, wherein the controller unit is adapted to directly receive controller input from a CAN bus of the vehicle.

15. The computing device according to claim 14, wherein the controller unit is configured to cause the multiplexing unit to display one of the external video signals when predefined vehicle conditions are detected based on the CAN bus input.

16. The computing device according to claim 15, wherein the predefined conditions include at least one of:

ignition of the vehicle, reverse driving, right turn, left turn.

17. The computing device according to claim 1, wherein the controller unit is adapted to receive controller input from at least one of:

one or more control switches positioned on a housing of the computing device, a power drop mechanism, a system reset mechanism and a power up key.

18. The computing device according to claim 1, wherein at least one of the one or more external video signals is recorded.

19. Vehicle equipment comprising:

(a) a computing device including;

i) a display screen;

ii) a central processing unit configured to run an operating system and at least one application, wherein the at least one application is operable to output an internal video signal adapted to be displayed on the display screen;

iii) a camera interface configured to receive a video input from one or more external cameras and to output one or more corresponding external video signals for display on the display screen;

iv) a multiplexing unit configured for receiving the internal video signal and the one or more external video signals, the multiplexing unit comprising a display output coupled to the display screen and being configured for selectively forwarding one of the internal video signal and the one or more external video signals on the display output towards the display screen; and

v) a controller unit configured for controlling the selective forwarding of the multiplexing unit based on controller input received by the controller unit; and

(b) at least one external camera configured for being arranged on a vehicle.

20. A vehicle including vehicle equipment comprising:

(a) a computing device including;

i) a display screen;

ii) a central processing unit configured to run an operating system and at least one application, wherein the at least one application is operable to output an internal video signal adapted to be displayed on the display screen;
