Description

Technical Field

[0001] The present invention belongs to the technical field of automotive equipment, and particularly relates to an infrared night vision control system for heavy-duty vehicles. Background Art

[0002] The driving environment conditions of heavy-duty vehicles, especially heavy-duty off-road vehicles, are complex. Equipping with an infrared night vision device can detect and display the road conditions in front of the vehicle in real time at night or in low visibility weather such as smoke, fog, rain, and snow, assisting vehicle driving. Currently, when a heavy-duty off-road vehicle is equipped with an infrared night vision device, a central control screen for displaying its image screen must be synchronously equipped, otherwise the infrared night vision function cannot be used. On the one hand, the central control screen is costly. On the other hand, due to the presence of the instrument panel of the heavy-duty off-road vehicle, the layout position of the central control screen is always not conducive to the driver's operation and viewing during driving, and it occupies a large amount of layout space on the console in the cab of the heavy-duty off-road vehicle, affecting the installation of other functional devices of the vehicle. Summary of the Invention

[0003] The present invention transmits an infrared function start or stop instruction to a body controller by setting an infrared control switch. After receiving the instruction, the body controller sends a CAN message to a combination meter to control the combination meter to provide or cut off the working power supply to the infrared night vision device. During operation, the infrared night vision device transmits an HDMI video signal to the combination meter for it to display the infrared night vision image. Thus, it solves the problem that currently, when a heavy-duty off-road vehicle is equipped with an infrared night vision device, a central control screen for displaying its image screen must be synchronously equipped, otherwise the infrared night vision function cannot be used.

[0004] The present invention is specifically implemented through the following technical solutions:

[0005] Provide an infrared night vision control system for heavy-duty vehicles, including an infrared night vision device, a combination meter, a body controller, and an infrared control switch;

[0006] The infrared control switch and the body controller are electrically connected; the infrared control switch is used to send an infrared start / stop instruction of the infrared night vision device to the body controller;

[0007] The body controller and the combination meter are connected by a CAN signal; the body controller is used to send a CAN message to the combination meter after receiving the infrared start / stop instruction;

[0008] The combined instrument and the infrared night vision device are connected by an electrical signal connection and an HDMI signal connection; when the vehicle body controller receives the infrared start instruction, after receiving the CAN message, the combined instrument is used to provide a working power supply to the infrared night vision device and synchronously jump its display interface to display the infrared night vision image; when the vehicle body controller receives the infrared stop instruction, after receiving the CAN message, the combined instrument is used to stop providing power to the infrared night vision device and synchronously jump its display interface to the driving interface.

[0009] As a further description of the present invention, the infrared night vision device is arranged at the front top outside the cab of the heavy-duty vehicle, and the infrared control switch is arranged on the console on the right side of the driver.

[0010] As a further description of the present invention, the combined instrument is arranged on the console directly in front of the driver, and the vehicle body controller is arranged on the cab body inside the console.

[0011] As a further description of the present invention, when the combined instrument interface is displaying the infrared night vision image, if the heavy-duty vehicle needs to perform a reverse operation, the combined instrument gives priority to responding to the reverse image function, and its display interface automatically jumps to the infrared night vision image screen after the reverse instruction disappears.

[0012] As a further description of the present invention, the combined instrument is used to provide a working power supply to the infrared night vision device after receiving the CAN message and synchronously jump its display interface to display the infrared night vision image specifically as follows:

[0013] The combined instrument is used to provide a working power supply to the infrared night vision device after receiving the CAN message, and synchronously jump its display interface to the infrared night vision image screen to start initialization. After the initialization is completed, the infrared night vision image is officially displayed.

[0014] As a further description of the present invention, the heavy-duty vehicle is a heavy-duty off-road vehicle.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:

[0016] 1. The heavy-duty off-road vehicle realizes the infrared night vision function without being equipped with a central control screen.

[0017] 2. Without being equipped with a central control screen, it not only reduces the manufacturing cost of the heavy-duty off-road vehicle, but also releases a large amount of space on the console in its cab, which is beneficial to the installation of other functional devices of the vehicle.

[0018] 3. The infrared night vision image is displayed on the combined instrument of the heavy-duty off-road vehicle, which is beneficial for the driver to view during driving, and the driving safety under special working conditions is improved.

[0019] 4. When the infrared night vision image is displayed on the combined instrument, it does not interfere with the use of the reverse image function of the heavy-duty off-road vehicle. When a reverse command is received, the combined instrument will give priority to responding to the reverse image function. After the reverse command disappears, its display interface will automatically jump back to the infrared night vision image to continue the infrared night vision function.

[0020] 5. The infrared function is turned on and off through an infrared control switch, which is simple and convenient. Description of the Drawings

[0028] The technical solution of the present invention will be explained below in conjunction with specific embodiments.

[0029] As Figure 1 shown, a heavy-duty vehicle infrared night vision control system is provided, including an infrared night vision device, a combined instrument, a body controller, and an infrared control switch;

[0030] The infrared control switch and the body controller are connected by an electrical signal; the infrared control switch is used to send an infrared start / stop instruction of the infrared night vision device to the body controller;

[0031] The body controller and the combined instrument are connected by a CAN signal; the body controller is used to send a CAN message to the combined instrument after receiving the infrared start / stop instruction;

[0032] The combined instrument and the infrared night vision device are connected by an electrical signal and an HDMI signal; when the body controller receives the infrared start instruction, the combined instrument is used to provide a working power supply to the infrared night vision device after receiving the CAN message, and synchronously jump its display interface to display the infrared night vision image; when the body controller receives the infrared stop instruction, the combined instrument is used to stop providing power to the infrared night vision device after receiving the CAN message, and synchronously jump its display interface to the driving interface.

[0033] Specifically, the infrared night vision device is arranged on the front top outside the cab of the heavy-duty vehicle, the infrared control switch is arranged on the console on the right side of the driver; the combined instrument is arranged on the console directly in front of the driver, and the body controller is arranged on the cab body inside the console.

[0034] The above infrared night vision control system for heavy-duty vehicles is especially applicable to the infrared night vision control system of heavy-duty off-road vehicles, and its specific working principle is as follows:

[0035] When the infrared night vision function is required, turn on the infrared control switch; after receiving the infrared start command from the infrared control switch, the body controller sends a CAN message to the combination instrument. After receiving this CAN message from the body controller, the combination instrument provides working power to the infrared night vision device, and synchronously jumps its display interface to the infrared night vision image screen to start the initialization. After the initialization is completed, the infrared night vision image is officially displayed; thus, the infrared night vision function is realized.

[0036] When it is necessary to stop the infrared night vision function, turn off the infrared control switch; after receiving the infrared stop command from the infrared control switch, the body controller sends a CAN message to the combination instrument. After receiving this CAN message from the body controller, the combination instrument stops providing power to the infrared night vision device and synchronously jumps its display interface to the driving interface.

[0037] In addition, it should be noted that when the heavy-duty off-road vehicle needs to perform a reversing action while the combination instrument interface is displaying the infrared night vision image, the combination instrument gives priority to responding to the reversing image function. After the reversing command disappears, its display interface will automatically jump back to the infrared night vision image screen to continue the infrared night vision function.

[0038] The above embodiments given are the better examples to implement the present invention, and the present invention is not limited to the above embodiments. Any non-essential addition or replacement made by those skilled in the art according to the technical features of the technical solution of the present invention shall fall within the protection scope of the present invention.
