Abstract

A vehicle monitoring system is provided. Based on operation contents on a remote control unit, an engine speed, a vehicle speed, a REV signal representing a gear shifting lever in the reverse position, a PKB signal representing a parking lever in the activated condition, a VICS signal outputted from a VICS receiving apparatus, etc., the system selects the most suitable video signal or display contents out of respective image signals generated from a TV tuner unit, a video unit and a navigation system, an image signal outputted from a rear camera unit, display contents expressing the abnormality on the vehicle and display contents of the VICS signal. After selecting the most suitable video signal or display contents, the system displays it on a TV monitoring unit.

Claims

1. A vehicle monitoring system for a vehicle, comprising:

at least one sensor attached to a part of the vehicle for determining at least one driving condition of the vehicle;

a monitoring unit mounted on the vehicle for displaying information about the vehicle;

a display determining section for determining what kind of picture to be displayed based on inputted command signals and the driving condition detected by the sensor; and

a display processing section for selecting at least one video signal out of a plurality of inputted signals based on the kind of picture determined to be displayed by the display determining section, producing a display signal corresponding to the selected at least one video signal with or without image-processing thereof, and allowing the monitoring unit to display the contents of the selected at least one video signal.

2. A vehicle monitoring system as claimed in claim 1, wherein when emergency information is inputted to the vehicle monitoring system the display determining section gives the emergency information priority over any other video signals and the display processing section allows the monitoring unit to display the contents of the emergency information thereon.

3. A vehicle monitoring system as claimed in claim 1, wherein when the vehicle moves in a rearward direction the display determining section determines whether or not a rear video signal representing a rear view of the vehicle is being inputted, and

when the rear video signal is inputted, the display determining section determines that the rear video signal is an object that is being displayed;

when the rear video signal is not inputted, the display determining section determines that the selected at least one video signal is the object that is being displayed.

4. A vehicle monitoring system as claimed in claim 1, wherein the the command signals are inputted by a remote control unit installed on the vehicle.

5. A vehicle monitoring system as claimed in claim 1, wherein the driving condition includes a speed of the vehicle.

6. A vehicle monitoring system as claimed in claim 1, wherein the driving condition is represented by a signal indicating an engine speed of the vehicle.

7. A vehicle monitoring system as claimed in claim 1, wherein the driving condition is represented by a REV signal indicating that a gear shifting lever occupies a reverse position for allowing the vehicle to move in a rearward direction.

8. A vehicle monitoring system as claimed in claim 1, wherein the driving condition is represented by a PKB signal indicating whether a parking brake of the vehicle is activated.

9. A vehicle monitoring system as claimed in claim 1, further comprising a VICS receiving apparatus, wherein the display determining section determines what kind of picture should be displayed based on the inputted command signals, the driving condition detected by the sensor, and a VICS signal from the VICS receiving apparatus.

10. A vehicle monitoring system as claimed in claim 1, wherein the monitoring unit displays the contents of the at least one video signal selected by the display processing section to at least one passenger of the vehicle.

11. A vehicle monitoring system as claimed in claim 10, wherein the vehicle is operated by a driver and the monitoring unit displays the contents of the at least one video signal selected by the display processing section to the driver.

12. A vehicle monitoring system as claimed in claim 11, wherein the monitoring unit displays the contents of the at least one video signal selected by the display processing section while the vehicle is in operation.

13. A vehicle monitoring system as claimed in claim 1, wherein the monitoring unit displays the contents of the at least one video signal selected by the display processing section while the driving condition is occurring.

14. A vehicle monitoring system as claimed in claim 13, wherein the monitoring unit displays the contents of the at least one video signal selected by the display processing section to at least one passenger of the vehicle.

15. A vehicle monitoring system as claimed in claim 1, wherein when the at least one sensor senses an emergency driving condition the display determining section determines that a picture representing the emergency driving condition is to be displayed and the display processing section selects a emergency video signal out of a plurality of inputted, non-emergency signals to be displayed and allows the monitoring unit to display the picture representing the emergency driving condition.

16. A vehicle monitoring system as claimed in claim 15, wherein the monitoring unit displays the picture representing the emergency driving condition to at least one passenger of the vehicle while the emergency driving condition is occurring.

17. A vehicle monitoring system for a vehicle, comprising:

at least one sensor attached to a part of the vehicle for determining at least one driving condition of the vehicle;

a monitoring unit mounted on the vehicle for displaying information about the vehicle;

an input device for receiving display command signals;

a display determining section for determining what kind of picture to be displayed based on the display command signals received by the input device and the driving condition detected by the sensor; and

a display processing section for selecting at least one video signal out of a plurality of inputted signals based on the kind of picture determined to be displayed by the display determining section, producing a display signal corresponding to the selected at least one video signal with or without image-processing thereof, and allowing the monitoring unit to display the contents of the selected at least one video signal to at least one passenger of the vehicle while the vehicle is in operation.

18. A vehicle monitoring system as claimed in claim 17, wherein when the at least one sensor senses an emergency driving condition the display determining section determines that a picture representing the emergency driving condition is to be displayed and the display processing section selects an emergency video signal out of a plurality of inputted, non-emergency signals and allows the monitoring unit to display the picture representing the emergency driving condition.

19. A vehicle monitoring system as claimed in claim 18, wherein the monitoring unit displays the picture representing the emergency driving condition while the emergency driving condition is occurring.

20. A vehicle monitoring system as claimed in claim 17, wherein when the vehicle moves in a rearward direction the display determining section determines whether or not a rear video signal representing a rear view of the vehicle is being inputted, and

when the rear video signal is inputted, the display determining section determines that the rear video signal is an object that is being displayed;

when the rear video signal is not inputted, the display determining section determines that the selected at least one video signal is the object that is being displayed.

21. A vehicle monitoring system as claimed in claim 17, wherein the driving condition is represented by at least one of a first signal indicating a speed of the vehicle, a second signal indicating an engine speed of the vehicle, a third signal indicating whether a gear shifting lever occupies a reverse position for allowing the vehicle to move in a rearward direction, and a fourth signal indicating whether a parking brake of the vehicle is activated.
