[0017] Preferably, when the automatic switch is closed, the domain controller controls the state of the left front or / and right front warning light according to the ambient light data, real-time rainfall, and the state of the left light switch, right light switch, and total switch, including:

[0019] When the preset first brightness threshold ≤ ambient light ≤ preset second brightness threshold, and the rainfall is less than the preset first rainfall threshold, if the left light switch or right light switch is detected to be pressed twice in succession, the domain controller controls the left front or right front warning light to flash three times; if the total switch is detected to be pressed twice in succession, the domain controller controls the left front and right front warning light to flash three times simultaneously.

[0020] When the ambient light is greater than the preset second brightness threshold, or the rainfall is greater than or equal to the preset first rainfall threshold, the domain controller prohibits the left front and right front warning light from being turned on, and sends a prompt signal to the vehicle-mounted large screen through the vehicle networking host to remind the user.

[0028] c. ADAS detects an oncoming vehicle;

[0029] d. The light state of the oncoming vehicle is high beam;

[0030] Then, the domain controller determines the oncoming vehicle to be on the left or right of the current vehicle according to the position coordinates of the oncoming vehicle, and controls the left or right front warning light to flash three times.

[0031] Preferably, when the automatic switch is on, if the following conditions are met simultaneously:

[0032] a. The preset first brightness threshold is less than or equal to the ambient light, and the ambient light is less than or equal to the preset second brightness threshold;

[0033] b. Rainfall is less than a preset first rainfall threshold;

[0034] c. ADAS detects an oncoming vehicle;

[0035] d. The light state of the oncoming vehicle is high beam;

[0036] Then, the domain controller sends a prompt signal and transmits it to the vehicle-mounted large screen through the vehicle networking host, and the user selects whether to execute the control of the left or right front warning light, if the selection is executed, the domain controller determines the oncoming vehicle to be on the left or right of the current vehicle according to the position coordinates of the oncoming vehicle, and controls the left or right front warning light to flash three times.

[0037] Preferably, if there are oncoming vehicles on both sides of the current vehicle, a prompt signal is sent and transmitted to the vehicle-mounted large screen through the vehicle networking host, and the user selects the state of the left or right front warning light.

[0038] Preferably, after the left or right front warning light flashes three times, the domain controller starts timing and continuously detects the light state of the oncoming vehicle, if the timing time is greater than a preset first timing threshold, and the light state of the oncoming vehicle is still high beam, the left or right front warning light is controlled to flash three times again.

[0039] The technical effect of the present application is:

[0040] The present application can remind the oncoming vehicle to turn off the high beam through the warning light with changed brightness when meeting, which can effectively improve the driving safety.

BRIEF DESCRIPTION OF DRAWINGS

[0044] Figure 1 A structural block diagram of a vehicle light reminding system is provided for the embodiments of the present application. DETAILED DESCRIPTION

[0045] The specific embodiments of the present application will be further described below with reference to the drawings, through the description of the embodiments, in order to help the technical personnel in the field to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present application, and to help its implementation. It should be noted that the words "first", "second" and the like in the present application are only convenient for the description of the technical solution and used as a distinction between components, and the corresponding component configuration may be the same or different, and the present application is not limited to this. In order to make the technical solution of the present application more clear, the present application is explained and described by the following embodiments.

[0046] The present embodiment provides a vehicle light reminding system, as shown in Figure 1 The system includes a domain controller, a vehicle networking host, a reminding lamp switch, a light detection sensor, a rain detection sensor, an ambient light detection sensor, an ADAS, a vehicle-mounted large screen, and left and right front reminding lamps, wherein the light detection sensor, the rain detection sensor, the ambient light detection sensor, the ADAS, and the left and right front reminding lamps are connected with the domain controller; the vehicle networking host is connected with the domain controller, the reminding lamp switch, and the vehicle-mounted large screen.

[0047] Specifically, the reminder light switch of the embodiment includes a left light switch, a right light switch, an automatic switch, and a total switch, which are connected with the vehicle networking host respectively. The left light switch is used to control the left front reminder light, the right light switch is used to control the right front reminder light, the total switch is used to control the left front and right front reminder lights simultaneously, and the automatic switch is used to switch the automatic mode of the left front and right front reminder light control. When the corresponding switch is triggered, the corresponding signal is generated and sent to the domain controller through the vehicle networking host. In specific implementation, the left light switch, the right light switch, the automatic switch, and the total switch can not only adopt a hard switch, but also can be configured as a soft switch integrated on the human-computer interface provided by the vehicle-mounted large screen, thereby improving the user experience and saving the interior layout space.

[0048] The vehicle networking host is a bridge for communication between the reminder light switch and the domain controller. Meanwhile, the domain controller can also send information (such as device fault information, options to be decided by the user, and data collected by each sensor) that needs to be displayed to the vehicle networking host. After corresponding analysis and processing, the vehicle networking host converts the information into image signals and sends them to the vehicle-mounted large screen for display. The vehicle-mounted large screen is correspondingly configured with a human-computer interaction interface, which can receive the user's instructions and forward them to the vehicle networking host while displaying the image. Meanwhile, the vehicle-mounted large screen can also integrate a voice device to assist in reminding according to the instructions of the vehicle networking host. The voice device is also connected with the vehicle networking host.

[0049] The light detection sensor is used to detect the light state (including high beam, low beam, etc.) of the oncoming vehicle; the rainfall detection sensor is used to detect the real-time rainfall; the ambient light detection sensor is used to detect the real-time ambient light data; the ADAS (Advanced Driver Assistance System) can obtain the position coordinates of the oncoming vehicle through various sensors (millimeter wave radar, laser radar, monocular and binocular cameras, and satellite navigation) installed on the vehicle. The light detection sensor of the embodiment includes a camera, which is connected with the domain controller and used to obtain the light state of the oncoming vehicle by collecting the light image of the oncoming vehicle. For the light image of the oncoming vehicle collected by the camera, the average gray value of the pixels is calculated as the brightness value of the corresponding light image, so that the light state of the oncoming vehicle can be determined according to the brightness value. Usually, a threshold setting method is adopted, for example, when the brightness value is greater than or equal to a preset brightness threshold, it is a high beam, otherwise it is a low beam or no light.

[0050] The domain controller is the brain of the system of the embodiment, which is used for data processing and logical judgment, and integrates the inputs of various sensors, reminder light switch states, and vehicle-mounted large screens to generate corresponding control instructions to control the states of the left front and / or right front reminder lights.

[0051] The left front reminding lamp and the right front reminding lamp are actual actuators of the system, and in specific implementation, the left front reminding lamp and the right front reminding lamp are installed together with the left and right headlamps of the vehicle, facilitating the structural layout design of the vehicle. The brightness of the reminding lamp is higher than that of the normal high beam, so as to remind the opposite vehicle to turn off the high beam. In specific implementation, the brightness of the reminding lamp can be flexibly set according to the needs, and the reminding effect can be improved by increasing the brightness when necessary.

[0052] The embodiment also provides an application method of the vehicle light reminding system, and the method comprises the following steps of: a user switches the automatic mode of the vehicle light reminding system through an automatic switch, the automatic switch is turned on to be in the automatic mode, and the automatic switch is turned off to be in the manual mode, and when the automatic switch is turned off:

[0053] The domain controller obtains the states of the left lamp switch, the right lamp switch and the total switch through the vehicle networking host, obtains real-time ambient light data through the ambient light detection sensor, and obtains real-time rainfall through the rainfall sensor.

[0054] The domain controller controls the states of the left front reminding lamp and / or the right front reminding lamp according to the ambient light data, the real-time rainfall and the states of the left lamp switch, the right lamp switch and the total switch.

[0055] When the automatic switch is turned on:

[0056] The domain controller obtains real-time ambient light data through the ambient light detection sensor, obtains the position coordinates of the opposite vehicle through the ADAS, obtains real-time rainfall through the rainfall sensor, and obtains the light state of the opposite vehicle through the light detection sensor.

[0057] The domain controller controls the states of the left front reminding lamp and / or the right front reminding lamp according to the ambient light data, the position coordinates of the opposite vehicle, the real-time rainfall and the light state of the opposite vehicle.

[0058] Specifically, when the automatic switch is turned off, the domain controller controls the states of the left front reminding lamp and / or the right front reminding lamp according to the ambient light data, the real-time rainfall and the states of the left lamp switch, the right lamp switch and the total switch, and the control comprises the following steps of:

[0059] When the ambient light is less than a preset first brightness threshold (1000lx) and the rainfall is less than a preset first rainfall threshold (10mm / 24h), at this time, the environment is dim and it is light rain or no rain, the normal use of low beam can meet the lighting needs, and the influence of the high beam of the oncoming vehicle on the vehicle is greater. Correspondingly, if the driver finds that the left or right oncoming vehicle does not turn off the high beam, the driver can press the left lamp switch or the right lamp switch, and if the press of the left lamp switch or the right lamp switch is detected, the domain controller controls the left front or right front warning light to flash three times. If there are oncoming vehicles on both sides that do not turn off the high beam, the driver can press the total switch, and if the press of the total switch is detected, the domain controller controls the left front and right front warning lights to flash three times at the same time.

[0060] When the preset first brightness threshold (1000lx) is less than or equal to the ambient light and less than the preset first rainfall threshold (10mm / 24h), at this time, the environment is relatively bright and it is light rain or no rain, and the influence of the high beam of the oncoming vehicle on the vehicle is smaller. Correspondingly, if the driver finds that the left or right oncoming vehicle does not turn off the high beam, the driver can press the left lamp switch or the right lamp switch twice in succession to prevent misoperation from interfering with other vehicles, and if the press of the left lamp switch or the right lamp switch twice in succession is detected, the domain controller controls the left front or right front warning light to flash three times. Similarly, if the press of the total switch twice in succession is detected, the domain controller controls the left front and right front warning lights to flash three times at the same time.

[0061] When the ambient light is greater than the preset second brightness threshold (7000lx) or the rainfall is greater than or equal to the preset first rainfall threshold (10mm / 24h), on the one hand, the ambient light is greater than 7000lx, the environment is bright, and the influence of the high beam of the oncoming vehicle on the vehicle is almost zero; on the other hand, the rainfall is greater than or equal to 10mm / 24h, the rainfall is too large, and the opening of the warning light will cause diffuse reflection, which affects the safety of driving. Therefore, no matter how the driver operates the left lamp switch, the right lamp switch or the total switch, the domain controller always prohibits the left front and right front warning lights from being turned on, and sends a prompt signal to the vehicle-mounted large screen through the vehicle networking host to remind the user, for example, the vehicle-mounted large screen displays the text "warning light opening condition not met". In the present application, the various brightness, rainfall thresholds and the like can be flexibly selected according to actual conditions in specific implementation.

[0062] In addition, the state of the left lamp switch, the right lamp switch and the total switch provided in the present embodiment also includes a long press state, and the long press state is used to control the left front or / and right front warning light to flash continuously. At the same time, in order to protect the safety of the drivers of the oncoming vehicles, the flashing duration is strictly limited. Specifically, when the automatic switch is turned off:

[0063] When the ambient light is less than a preset first brightness threshold and the rainfall is less than a preset first rainfall threshold, if the left light switch or the right light switch is detected to be long pressed, the domain controller correspondingly controls the left front or right front warning light to flash for a preset first time and then stop; if the total switch is detected to be long pressed, the domain controller correspondingly controls the left front and right front warning light to flash simultaneously for a preset first time and then stop.

[0064] When the preset first brightness threshold is less than or equal to the ambient light and less than or equal to the preset second brightness threshold, and the rainfall is less than the preset first rainfall threshold, if the left light switch or the right light switch is detected to be long pressed twice in succession, the domain controller correspondingly controls the left front or right front warning light to flash for a preset first time and then stop; if the total switch is detected to be long pressed twice in succession, the domain controller correspondingly controls the left front and right front warning light to flash simultaneously for a preset first time and then stop. The first time in the embodiment, i.e., the flashing duration, is set to 5 s, which serves to remind and prevent interference with the driver of an oncoming vehicle for a long time. In a specific implementation, the flashing duration can also be flexibly selected according to actual conditions.

[0065] When the automatic switch is turned on, the domain controller correspondingly controls the state of the left front or / and right front warning light according to the ambient light data, the position coordinates of the oncoming vehicle, the real-time rainfall, and the light state of the oncoming vehicle, including:

[0066] If the following conditions are met simultaneously:

[0067] a. The ambient light is less than a preset first brightness threshold;

[0068] b. The rainfall is less than a preset first rainfall threshold;

[0069] c. The ADAS detects the oncoming vehicle;

[0070] d. The light state of the oncoming vehicle is high beam;

[0071] Then, the domain controller determines whether the oncoming vehicle is on the left or right of the current vehicle according to the position coordinates of the oncoming vehicle, and correspondingly controls the left front or right front warning light to flash three times. For example, the domain controller receives the input signal coordinates of the ADAS to determine that the oncoming vehicle is on the left, sends a control signal to turn on the left front warning light, and flashes three times and then automatically turns off; if the input signal coordinates of the ADAS determine that the oncoming vehicle is on the right, a control signal is sent to turn on the right warning light.

[0072] Further, when the automatic switch is turned on, if the following conditions are met simultaneously:

[0073] a. The preset first brightness threshold is less than or equal to the ambient light and less than or equal to the preset second brightness threshold;

[0074] b. The rainfall is less than a preset first rainfall threshold;

[0075] c. ADAS detects oncoming vehicle;

[0076] d. The light state of the oncoming vehicle is high beam;

[0077] Then, the domain controller sends a prompt signal and transmits it to the vehicle-mounted large screen through the vehicle networking host. The vehicle-mounted large screen provides a human-machine interface to the user. At this time, the urgency of using the warning light is not high, and the user selects whether to execute the left front or / and right front warning light control. Under the premise of ensuring safety, the user's willingness is fully respected. If the selection is executed, the domain controller determines the oncoming vehicle on the left or right of the current vehicle according to the position coordinates of the oncoming vehicle, and controls the left front or right front warning light to flash three times.

[0078] At the same time, when the automatic switch is on, if there are oncoming vehicles on both sides of the current vehicle, a prompt signal is sent and transmitted to the vehicle-mounted large screen through the vehicle networking host. The user selects the state of the left front or / and right front warning light. Under the premise of ensuring safety, the user's willingness is fully respected.

[0079] To ensure the effect of automatic light warning, when the automatic switch is on, the domain controller starts timing and continuously detects the light state of the oncoming vehicle after the left front or / and right front warning light flashes three times. If the timing time is greater than the first preset timing threshold, the light state of the oncoming vehicle is still high beam, and the left front or / and right front warning light flashes three times again. The first timing threshold of the present embodiment is set to 5s, which can be flexibly selected according to actual conditions in specific implementation.

[0080] To ensure safety, when the automatic switch is on, any of the following conditions is met:

[0081] a. The ambient light is greater than the second preset brightness threshold;

[0082] b. The rainfall is greater than the first preset rainfall threshold;

[0083] c. Any fault (including no signal feedback) of the light detection sensor, the rainfall detection sensor, the ambient light detection sensor, and the ADAS;

[0084] Then, the domain controller prohibits the operation of the left front and right front warning lights. At the same time, the domain controller can send a prompt to the vehicle networking host, and the vehicle networking host displays or prompts the driver through the voice on the vehicle large screen. Among them, if the prohibition of operation is caused by any fault of the light detection sensor or ADAS, the vehicle large screen can also display the fault information, and suggest the user to switch to the manual mode. If the prohibition of operation is caused by any fault of the rain detection sensor or the ambient light detection sensor, the vehicle large screen displays the fault information, and reminds the user to repair in time, because the manual mode also needs the participation of the rain detection sensor and the ambient light detection sensor.

[0085] In a preferred embodiment of the present application, for the left light switch, the right light switch, the total switch and the automatic switch integrated on the man-machine interface provided by the vehicle large screen, a fault warning method of the left front and right front warning lights is also set, which comprises: when the left front warning light fails, a signal is sent to the domain controller, and the domain controller sends a related signal to the vehicle networking host, and the vehicle networking host sends a signal to the vehicle large screen, at this time, the left light switch on the vehicle large screen changes from green to gray and cannot be operated; similarly, when the right front warning light fails, the right light switch on the vehicle large screen changes from green to gray; at the same time, the total switch and the automatic switch buttons are also grayed out in the failure state. At the same time, the man-machine interface also reminds the high beam failure, and the use needs to be repaired.

[0086] The above describes the present application in conjunction with the drawings. Obviously, the specific implementation of the present application is not limited by the above method. As long as various non-essential improvements are made by using the method concept and technical solution of the present application; or without improvement, the above concept and technical solution of the present application are directly applied to other occasions, which are within the protection scope of the present application.

The oncoming vehicle's lights are in high beam mode; Then, the domain controller determines whether the oncoming vehicle is on the left or right of the current vehicle according to the position coordinates of the oncoming vehicle, and controls the left front or right front warning light to flash three times accordingly.

8. The application method of the vehicle light reminder system according to claim 4, characterized in that: When the automatic switch is turned on, if the following conditions are met at the same time: a. The preset first brightness threshold ≤ ambient light ≤ the preset second brightness threshold; b. The rainfall is less than a preset first rainfall threshold; c. ADAS detects an oncoming vehicle; d. The oncoming vehicle's lights are in high beam mode; Then, the domain controller sends a prompt signal and transmits it to the in-vehicle large screen through the Internet of Vehicles host. The user chooses whether to execute the control of the left front or right front warning light. If the user chooses to execute, the domain controller determines whether the oncoming vehicle is on the left or right of the current vehicle based on the position coordinates of the oncoming vehicle, and controls the left front or right front warning light to flash three times accordingly.

9. The application method of the vehicle light warning system according to claim 7 or 8, characterized in that: If there are oncoming vehicles on both the left and right sides of the current vehicle, a prompt signal is sent and transparently transmitted to the in-vehicle large screen through the Internet of Vehicles host, and the user selects the status of the left front or right front warning light.

10. The application method of the vehicle light reminder system according to claim 9, characterized in that: After the operation of flashing the left front or right front warning light three times is performed once, the domain controller starts timing and continuously detects the light status of the oncoming vehicle. If the timing time is greater than the preset first timing threshold and the light status of the oncoming vehicle is still high beam, the left front or right front warning light is controlled to flash three times again.
