Abstract

A vehicular monitor is controlled by either a manual control device or an automatic control device. In response to an activation state of one of the manual control device and the automatic control device, a first actuating signal is asserted to adjust the working condition of the vehicular monitor according to the first actuating signal. In response to an activation state of the other of the manual control device and the automatic control device, the first actuating signal is asserted and a second actuating signal is asserted in stead to adjust the working condition of the vehicular monitor according to the second actuating signal. The vehicular monitor is for example a rearview mirror, a camera or a display. The working condition of the vehicular monitor is adjusted for example by moving or rotating the rearview mirror, changing focus of camera or zooming in/out the display.

Claims

1. A vehicular monitor actuating device for use with a vehicular monitor, said vehicular monitor being actuated by said vehicular monitor actuating device in a first situation and by a manual control device in a second situation, said vehicular monitor actuating device comprising:

a micro-controller in communication with said manual control device, asserting a first actuating signal in said first situation, and suspending said first actuating signal and asserting a second actuating signal in said second situation; and

an actuating signal channel in communication with said micro-controller and said vehicular monitor for transmitting therethrough said first or said second signal to said vehicular monitor for changing a working condition of said vehicular monitor.

2. The vehicular monitor actuating device according to claim 1 wherein said first situation is determined by an output of a vehicle status indicator.

3. The vehicular monitor actuating device according to claim 2 wherein said vehicle status indicator is selected from a group consisting of an electronic compass, a global positioning system (GPS), a steering-wheel turning detector, a tire-angle switch, a vehicle stability control (VSC) system, an electronic stability program (ESP), a yaw sensor, an attitude indicator, an accelerating indicator, a mercury switch, a reverse gear sensor and a back-warning radar.

4. The vehicular monitor actuating device according to claim 1 wherein said second situation is determined by manually operating a switch.

5. The vehicular monitor actuating device according to claim 1 wherein said suspended first actuating signal is recovered after said second actuating signal is completed.

6. The vehicular monitor actuating device according to claim 1 wherein said actuating signal channel is selected from vehicle cables, vehicular digital bus and wireless transmission channel.

7. The vehicular monitor actuating device according to claim 6 wherein said vehicular digital bus is a controller area network (CAN) bus or a vehicle area network (VAN) bus.

8. The vehicular monitor actuating device according to claim 1 wherein said vehicular monitor is selected from a rearview mirror, a camera and a display.

9. The vehicular monitor actuating device according to claim 8 wherein said camera is a CCD camera or a CMOS camera.

10. The vehicular monitor actuating device according to claim 1 wherein said working condition is changed by moving said vehicular monitor, rotating said vehicular monitor, changing focus of said vehicular monitor or zooming said vehicular monitor.

11. A vehicular monitor actuating device for use with a vehicular monitor, said vehicular monitor being actuated by said vehicular monitor actuating device in a first situation and by a manual control device in a second situation, said vehicular monitor actuating device comprising:

a micro-controller in communication with said manual control device, asserting a first actuating signal in said second situation, and suspending said first actuating signal and asserting a second actuating signal in said first situation; and

an actuating signal channel in communication with said micro-controller and said vehicular monitor for transmitting therethrough said first or said second signal to said vehicular monitor for changing a working condition of said vehicular monitor.

12. The vehicular monitor actuating device according to claim 11 wherein said first situation is determined by an output of a vehicle status indicator, and said second situation is determined by manually operating a switch.

13. The vehicular monitor actuating device according to claim 12 wherein said vehicle status indicator is selected from a group consisting of an electronic compass, a global positioning system (GPS), a steering-wheel turning detector, a tire-angle switch, a vehicle stability control (VSC) system, an electronic stability program (ESP), a yaw sensor, an attitude indicator, an accelerating indicator, a mercury switch, a reverse gear sensor and a back-warning radar.

14. The vehicular monitor actuating device according to claim 11 wherein said actuating signal channel is selected from vehicle cables, vehicular digital bus and wireless transmission channel.

15. The vehicular monitor actuating device according to claim 14 wherein said vehicular digital bus is a controller area network (CAN) bus or a vehicle area network (VAN) bus.

16. The vehicular monitor actuating device according to claim 11 wherein said vehicular monitor is selected from a rearview mirror, a camera and a display.

17. The vehicular monitor actuating device according to claim 16 wherein said camera is a CCD camera or a CMOS camera.

18. A method for actuating a vehicular monitor, said vehicular monitor being controlled by either a manual control device or an automatic control device, said method comprising steps of:

asserting a first actuating signal in response to an activation state of one of said manual control device and said automatic control device;

adjusting a working condition of said vehicular monitor according to said first actuating signal;

suspending said first actuating signal in response to an activation state of the other of said manual control device and said automatic control device, and asserting a second actuating signal in stead; and

adjusting a working condition of said vehicular monitor according to said second actuating signal.

19. The method according to claim 18 wherein said automatic control device is selected from a group consisting of an electronic compass, a global positioning system (GPS), a steering-wheel turning detector, a tire-angle switch, a vehicle stability control (VSC) system, an electronic stability program (ESP), a yaw sensor, an attitude indicator, an accelerating indicator, a mercury switch, a reverse gear sensor and a back-warning radar.

20. The method according to claim 18 wherein said first actuating signal is asserted in response to said activation state of said automatic control device, and said second actuating signal is asserted in response to said activation state of said manual control device.

21. The method according to claim 18 wherein said first actuating signal is asserted in response to said activation state of said manual control device, and said second-actuating signal is asserted in response to said activation state of said automatic control device.
