DEVICE FOR SWITCHING BETWEEN A VEHICLE NAVIGATION SYSTEM AND A NIGHT VISION SYSTEM AS WELL AS SWITCHING METHOD THEREOF
First Claim
1. A device for switching between a vehicle navigation system and a night vision system, wherein, it comprises:
- a navigation system switching module and a night vision system switching module;
The said navigation system switching module connects to a navigation system, configured to control the navigation system starting a navigation mode and displaying the navigation info, or control the navigation system starting a night vision mode and transmitting the night vision info from a night vision system to the navigation system before displaying, based on the input operation;
The said night vision system switching module connects to the night vision system, configured to control the night vision system starting a night vision mode and displaying the night vision info, or control the night vision system starting the navigation mode and transmitting the navigation info from the navigation system to the night vision system before displaying, based on the input operation;
The said navigation system connects to the night vision system through a video signal cable, configured to transmit the night vision info or the navigation info between the navigation system and night vision system; and
The said navigation system switching module connects to the night vision system switching module through a communication cable, configured to transmit the according parameters of the navigation system or the night vision system, and adjust the according working status of the night vision system or the navigation system.

Abstract
The present invention discloses a device for switching between a vehicle navigation system and the night vision system as well as switching method thereof. The said device includes a navigation system switching module connects to the navigation system and a night vision system module connects to the night vision system, while both systems are connecting through video signal cable, and the switching modules are connecting through communication cable. Both switching modules are able to control any system switching into either mode, and transmit any info into either system then displaying the info. Therefore, the navigation system is also able to display night vision info and vice versa, which provides convenience to the users and improves the driving safety.

6. A switching method for the navigation system of a device for switching between a vehicle navigation system and a night vision system, wherein, it comprises the following steps:
-
A. turn on a navigation system, initialize a navigation system switching module and start a navigation mode;
A navigation video signal cable transmits navigation video signals collected by a camera of the navigation system to the navigation system for displaying;B. real-time detect the using status of a switch button, if the switch button is detected to be pressed, judge if the pressed switch button is a first navigation switch button;
if so, continue to step C;
otherwise, go to step D;C. judge if the mode of current navigation system is the navigation mode;
if so, keep the current navigation mode unchanged;
otherwise, switch a current night vision mode to the navigation mode, the navigation video signal cable transmits navigation video signals collected by the camera of the navigation system to the navigation system for displaying, and the navigation system starts the navigation mode; andD. ensure a first night vision switch button is pressed, judge if the current mode of the navigation system is the night vision mode;
if so, keep the current night vision mode unchanged;
otherwise, switch the current navigation mode to the night vision mode, and the night vision video signal cable transmits night vision video signals collected by a camera of night vision system to the navigation system for displaying, and the navigation system starts the night vision mode. - View Dependent Claims (7)

8. A switching method for a night vision system of a device for switching between a vehicle navigation system and a night vision system, wherein, it comprises the following steps:
-
a. turn on a night vision system, initialize a night vision system switching module and start a night vision mode;
A night vision video signal cable transmits night vision video signals collected by a camera of the night vision system to the night vision system for displaying;b. real-time detect the using status of a switch button, if the switch button is detected to be pressed, judge if the pressed switch button is a second navigation switch button;
if so, continue to step C;
otherwise, go to step D;c. judge if the current mode of the night vision system is a navigation mode;
if so, keep the current mode unchanged;
otherwise, switch the current night vision mode to a navigation mode, a navigation video signal cable then transmits navigation video signals collected by a camera of navigation system to the night vision system for displaying, and the night vision system starts a navigation mode; andd. ensure the second night vision switch button is pressed, judge if the current mode of the night vision system is the night vision mode;
if so, keep the current mode unchanged;
otherwise, switch the current navigation mode to the night vision mode, and the night vision video signal cable transmits night vision video signals collected by the camera of the night vision system to the night vision system for displaying, and the night vision system starts the night vision mode. - View Dependent Claims (9)
