Description

A vehicle-mounted device that can automatically switch image information outside the vehicle according to the state of the vehicle

Technical field:

The invention relates to a vehicle-mounted device capable of automatically switching image information outside the vehicle according to the state of the vehicle.

Background technique:

Although the existing vehicle-mounted devices used in automobiles are equipped with a front camera for obtaining image information of the situation in front of the outside of the car, the front camera can only enter the working state according to the instructions of the driver, and the driver cannot start the car at the same time. The front camera is automatically turned on, so that it is impossible to provide the driver with image information of the situation in front of the car at the first time when the car is ignited. When a child is a child, it cannot be discovered in time due to the limited viewing angle of the driver in the car. At this time, if the driver puts the forward gear and makes the car move forward, it will cause an accident. In addition, the existing vehicle-mounted devices used in automobiles usually have a reversing radar function, but they cannot further provide the driver with specific image information behind the car, so there are still certain hidden dangers in reversing safety.

Invention content:

The purpose of the present invention is to provide a vehicle-mounted device that can automatically switch the image information outside the vehicle according to the state of the vehicle, which can automatically turn on the front camera when the vehicle is ignited and started, and provide the driver with the image information of the front situation outside the vehicle at the first time. It can also automatically turn on the rear camera when the car is reversing, and provide the driver with image information of the situation outside and behind the car at the first time, improving the safe driving factor.

A vehicle-mounted device that can automatically switch image information outside the vehicle according to the state of the vehicle, is characterized in that it at least includes: a front camera, a rear camera, a CPU processing unit, and a display screen, and the viewing direction of the front camera is aligned with the front and tilted downward Overhead shooting, the viewfinder direction of the rear camera is aligned with the rear and tilted downward, the output ends of the front camera and the rear camera are respectively electrically connected to the input ends of the CPU processing unit, and the output ends of the CPU processing unit are connected to the display screen Electrically connected; when the car is ignited and started, the front camera is automatically turned on to obtain the image information of the front situation outside the car, and the detected image signal is sent to the CPU processing unit, and the CPU processing unit processes and analyzes the image signal Send to the display screen display; when the car is reversing, the rear camera is automatically turned on to obtain the image information of the rear situation outside the car, and the detected image signal is sent to the CPU processing unit, and the CPU processing unit processes the image signal After analysis, it is sent to the display screen for display.

The front camera and/or the rear camera are infrared cameras.

The present invention can automatically turn on the front camera when the car is ignited and started to provide the driver with image information of the front situation outside the car at the first time, and can also automatically turn on the rear camera when the car is reversing to provide the driver with the image information of the outside of the car at the first time. The image information of the rear situation improves the safe driving factor. The front camera and/or the rear camera are infrared cameras, which can obtain clearer image information even in places with low light.

Description of drawings:

Fig. 1 is a functional block diagram of the present invention.

Detailed ways:

As shown in Figure 1, a kind of vehicle-mounted device that can automatically switch the image information outside the car according to the state of the car, at least includes: a front camera 1, a rear camera 4, a CPU processing unit 2, and a display screen 3, the viewfinder of the front camera 1 The direction is to align with the front and tilt downward to shoot, and the viewfinder direction of the rear camera 4 is to align with the rear and tilt to shoot downward, and the output ends of the front camera 1 and the rear camera 4 are electrically connected to the input ends of the CPU processing unit 2 respectively , the output end of the CPU processing unit 2 is electrically connected to the display screen 3; when the ignition of the car is started, the front camera 1 is automatically turned on to obtain the image information of the front situation outside the car, and the detected image signal is sent to the CPU Processing unit 2, the CPU processing unit 2 processes and analyzes the image signal and sends it to the display screen 3 for display; when the car is reversing, the rear camera 4 is automatically turned on to obtain the image information of the rear situation outside the car, and will detect The image signal is sent to the CPU processing unit 2, and the CPU processing unit 2 processes and analyzes the image signal and sends it to the display screen 3 for display. The front camera 1 and/or the rear camera 4 are infrared cameras.

The present invention can automatically turn on the front camera 1 when the car is ignited and started to provide the driver with image information of the situation in front of the outside of the car at the first time, and can also automatically turn on the rear camera 4 when the car is reversing to provide the driver with the first time. The image information of the car's exterior and rear conditions improves the safety driving factor. The front camera 1 and/or the rear camera 4 are infrared cameras, which can obtain clearer image information even in places with low light.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the implementation scope of the present invention. All equivalent changes and modifications made according to the scope of the patent of the present invention fall within the scope covered by the patent of the present invention.
