The type, number and proportion of the components during actual implementation can be arbitrarily changed, and the layout type of the components can be more complex.

[0022] In the following description, numerous specific details are discussed in order to provide a thorough explanation of embodiments of the present application. However, it will be apparent to one of ordinary skill in the art that embodiments of the present application can be practiced without these specific details. In other instances, well-known structures and devices are not described in detail in order to avoid obscuring embodiments of the present application.

[0023] Referring to Figure 1 , Figure 1 A flow chart of a high beam reminding method according to an embodiment of the present application is shown in Figure 1 In an exemplary embodiment, the high beam reminding method comprises steps S110 to S140, which are described in detail as follows.

[0024] In step S110, high beam interference influence information in a driving environment of a host vehicle (hereinafter referred to as host vehicle) is acquired when it is identified that a rear vehicle (hereinafter referred to as rear vehicle) turns on a high beam.

[0025] The embodiment of the present application can determine whether the rear vehicle turns on the high beam through a related sensor, for example, by comprehensively analyzing whether the rear vehicle turns on the high beam in combination with an environment image collected by a visual sensor, a rear vehicle light image, and a light sensing value collected by a rearview mirror light sensor.

[0026] The embodiment of the present application can be executed in the case of driving at night, and steps S110 to S140 In step S120, N target interference distances are determined based on the high beam interference influence information and preset N initial interference distances.

[0027] The N is a positive integer, and the N initial interference distances can be preset. The high beam interference influence information refers to information affecting the high beam interference distance. According to the embodiment of the present application, the dynamic target interference distance is obtained according to the high beam interference influence information and the initial interference distance, and then the high beam interference is judged, which is beneficial to improve the judgment accuracy.

[0028] Hereinafter, the high beam interference influence information is exemplarily described by taking non-vehicle light environment light information as an example.

[0029] When the ambient light information (excluding vehicle headlights) indicates strong ambient light and the distance between the following vehicle and the vehicle is greater than the initial interference distance, the high beams of the following vehicle may not interfere with the vehicle. However, since the visual interference caused by high beams is more pronounced when the ambient light information (excluding vehicle headlights) indicates weak ambient light and the distance between the following vehicle and the vehicle is greater than the initial interference distance, the high beams of the following vehicle may interfere with the vehicle. Therefore, directly determining whether high beam interference exists based on a fixed initial interference distance is not accurate enough. It is necessary to obtain a dynamic target interference distance based on the high beam interference impact information and the initial interference distance, and then perform high beam interference identification.

[0030] Step S130: Based on the distance between the following vehicle and the vehicle itself, and the interference distances of the N targets, determine whether the high beams of the following vehicle interfere with the vehicle itself.

[0031] When N equals 1, if the distance between the following vehicle and the vehicle is greater than the target interference distance, it can be directly determined that there is no interference; otherwise, interference exists.

[0032] When N is greater than 1 and there are multiple target interference distances that decrease sequentially, these distances can correspond to different levels of interference. If the distance between the following vehicle and the vehicle is greater than the maximum target interference distance, it can be determined that there is no interference; otherwise, interference exists, and the corresponding level of interference can be determined based on the multiple target interference distances that decrease sequentially.

[0033] Step S140: In the event of interference, issue a high beam interference warning message to the vehicle behind.

[0034] In this embodiment, the vehicle's equipment can send a high beam interference warning message to the following vehicle, such as sending a text warning message about high beam interference through taillight signals or a display screen, or sending a voice warning message about high beam interference through external speakers.

[0035] The embodiments of the present invention can accurately identify whether the high beams of the following vehicle interfere with the vehicle through the above steps, and can remind the following vehicle, which is beneficial to driving safety.

[0036] In one embodiment of the present invention, the high beam interference impact information includes weather information, and the step of determining N target interference distances based on the high beam interference impact information and N preset initial interference distances includes: If the weather information meets the first strong interference condition, a first correction coefficient is determined, wherein the first correction coefficient is greater than 1; The N target interference distances are determined by multiplying the first correction coefficient by the N initial interference distances respectively.

[0037] The aforementioned weather information includes information used to determine whether the weather is high humidity. High humidity can increase the time it takes for following vehicles to maintain a safe following distance (e.g., due to slippery roads caused by rain); furthermore, under high humidity, water droplets form a film on the rearview mirror, and when high beams are applied, the raindrops act like tiny mirrors, reflecting the light and making it more diffused and brighter, thus increasing high beam interference. Therefore, the initial interference distance can be increased based on the aforementioned first correction coefficient (a preset value greater than 1) to obtain the target interference distance.

[0038] Weather information can be obtained from weather stations or from vehicle sensors.

[0039] In this embodiment of the invention, when the weather information meets the first strong interference condition, the initial interference distance is expanded by N based on the first correction coefficient to obtain N target interference distances, which helps to improve the accuracy of target interference distance, thereby improving the accuracy of high beam interference identification and warning.

[0040] In one embodiment of the present invention, the weather information includes rainfall and / or ambient humidity, and determining a first correction coefficient when the weather information satisfies a first strong interference condition includes: The first correction coefficient is determined when the rainfall is greater than a preset rainfall threshold and / or the ambient humidity is greater than a preset humidity threshold.

[0041] In this embodiment, rainfall and ambient humidity can be obtained through a meteorological platform or through vehicle body sensors. The vehicle body sensors include a solar rainfall sensor and a humidity sensor; specifically, the rainfall can be obtained through the solar rainfall sensor, and the ambient humidity can be obtained through the humidity sensor.

[0042] When the rainfall exceeds the preset rainfall threshold and / or the ambient humidity exceeds the preset humidity threshold, the following vehicle needs more time to control the distance, and the high beams of the following vehicle cause stronger interference to the following vehicle. Therefore, the above-mentioned first correction coefficient can be determined to expand the N initial interference distances to obtain N target interference distances.

[0043] In one embodiment of the present invention, the high beam interference impact information further includes non-vehicle headlight ambient light information, and the step of determining N target interference distances based on the high beam interference impact information and N preset initial interference distances includes: When the non-vehicle headlight ambient light information meets the second strong interference condition, a second correction coefficient is determined, and the second correction coefficient is greater than 1. The N target interference distances are determined by multiplying the second correction coefficient by the N initial interference distances respectively.

[0044] Ambient light other than vehicle headlights reduces the impact of high beams. When there is no ambient light other than vehicle headlights (such as streetlights) in the vicinity, the visual interference caused by the high beams of following vehicles is more obvious. Therefore, the target interference distance mentioned above can be determined based on information about ambient light other than vehicle headlights.

[0045] The aforementioned non-vehicle headlight ambient light information may include ambient light intensity and environmental images, which can be acquired through vision sensors and light sensors (such as a light sensor installed on the roof of the vehicle). The aforementioned non-vehicle headlight ambient light information satisfies the second strong interference condition when there are no ambient light sources in the surrounding area. For example, when the light sensor on the roof of the vehicle detects that the ambient light intensity is lower than a set light-sensing threshold, or when the vision sensor detects that there are no streetlights in the environment, the second strong interference condition is satisfied.

[0046] In this embodiment of the invention, when the ambient light information of the non-vehicle headlights meets the second strong interference condition, the high beams of the following vehicle cause stronger interference to the vehicle. Therefore, the above-mentioned second correction coefficient (a preset value greater than 1) can be determined to expand the N initial interference distances to obtain N target interference distances.

[0047] In some embodiments, if the weather information meets the first strong interference condition and the non-vehicle headlight ambient light information meets the second strong interference condition, the above-mentioned N target interference distances can be determined simultaneously based on the product of the first correction coefficient, the second correction coefficient, and N initial interference distances.

[0048] In some embodiments, if the weather information does not meet the first strong interference condition and the non-vehicle headlight ambient light information does not meet the second strong interference condition, then there is no need to determine the first correction coefficient and the second correction coefficient, and the N target interference distances are respectively equal to the N initial interference distances.

[0049] In one embodiment of the present invention, the N target interference distances include, in descending order, light target interference distance, moderate target interference distance, and heavy target interference distance. Determining whether the high beams of the rear vehicle interfere with the vehicle based on the distance between the rear vehicle and the vehicle itself, and the N target interference distances, includes: If the distance between the following vehicle and the vehicle itself is greater than the distance of the minor target interference, then it is determined that the high beams of the following vehicle do not interfere with the vehicle itself. If the distance between the following vehicle and the vehicle itself is greater than the moderate target interference distance and less than or equal to the mild target interference distance, then it is determined that the high beams of the following vehicle are causing mild interference to the vehicle itself. If the distance between the following vehicle and the vehicle itself is greater than the median interference distance and less than or equal to the moderate target interference distance, then it is determined that the high beams of the following vehicle are causing moderate interference to the vehicle itself. The median interference distance is the average of the moderate target interference distance and the severe target interference distance. If the distance between the following vehicle and the vehicle itself is less than or equal to the median interference distance, then it is determined that the high beams of the following vehicle are causing severe interference to the vehicle itself.

[0050] The aforementioned light target interference range, moderate target interference range, and heavy target interference range need to be determined based on the information on the impact of high beam interference and the light, moderate, and heavy initial interference ranges.

[0051] The initial interference distances for mild, moderate, and severe interference are all pre-calibrated distances. For example, the light projected by the high beams of a following vehicle onto the interior and exterior rearview mirrors at different distances can be simulated using in-vehicle and out-of-vehicle light emitters. The driver then determines the following distances: mild visual impairment, where visual impairment begins to occur, is calibrated as the mild initial interference distance K3; moderate visual impairment, where visual impairment has already occurred, is calibrated as the moderate initial interference distance K2; and severe visual impairment, where it is impossible to observe the rear through the rearview mirrors, is calibrated as the severe initial interference distance K1.

[0052] This invention, by setting mild, moderate, and severe target interference distances, can determine the interference intensity of a following vehicle's high beams by combining the distance between the following vehicle and the vehicle itself. Furthermore, this invention determines severe interference only when the distance between the following vehicle and the vehicle is less than or equal to the median interference distance, rather than only when it is less than or equal to the severe target interference distance (less than the median interference distance). This facilitates issuing high beam interference warnings corresponding to severe interference in advance.

[0053] In one embodiment of the present invention, the step of issuing a high beam interference warning message to the following vehicle in the presence of interference includes: In the presence of interference, a corresponding high beam interference warning message is issued to the following vehicle according to the degree of interference, which is either mild interference, moderate interference, or severe interference.

[0054] As an example, the high beam interference warning message corresponding to mild interference is, for example, "Your high beams are causing mild visual interference to this vehicle. Please increase your following distance." The high beam interference warning message corresponding to moderate interference is, for example, "Your high beams are causing moderate visual interference to this vehicle. Please increase your following distance." The high beam interference warning message corresponding to severe interference is, for example, "Your high beams are causing severe visual interference to this vehicle. Please turn off your high beams immediately."

[0055] In this embodiment of the invention, a corresponding high beam interference warning message is sent to the following vehicle according to the degree of interference, which helps to remind the following vehicle to take corresponding measures, thereby further improving driving safety.

[0056] In one embodiment of the present invention, after issuing a high beam interference warning message to the following vehicle in the presence of interference, the method further includes: If the following vehicle turns off its high beams, and if turning them back on will not interfere with the vehicle, then a reminder message will be sent to the following vehicle indicating that it is safe to turn on its high beams.

[0057] The following vehicle turning on its high beams again will not interfere with this vehicle, for example, if the following vehicle has controlled the distance to this vehicle by slowing down or other means and the distance is greater than the mild interference threshold.

[0058] The above-mentioned reminder message for turning on high beams, such as "Visibility interference eliminated, high beams can be turned on for illumination."

[0059] Through the above steps, this invention can promptly remind following vehicles to turn on their high beams, which is beneficial to the safe driving of following vehicles.

[0060] In some embodiments, after issuing a high beam interference warning to the following vehicle in the presence of interference, the method further includes: If the vehicle behind turns off its high beams, send a thank-you message to the vehicle behind, such as: "Thank you for turning off your high beams so the visual interference can be resolved." If the distance between the following vehicle and this vehicle changes from less than or equal to the moderate target interference distance to greater than the moderate target interference distance, a second thank-you message is sent to the following vehicle, such as: "Thank you for maintaining the distance, the visual interference has been eliminated." If the visual sensor and the rearview mirror light sensor detect that the visual interference caused by the following vehicle changing lanes has been eliminated, the high beam interference warning message can be canceled directly.

[0061] In one embodiment of the present invention, after determining whether the high beams of the following vehicle interfere with the vehicle itself, the method further includes: If there is no interference, then determine the duration for which the following vehicle has its high beams on. Based on the high beam interference impact information and the preset initial duration threshold, the target duration threshold is determined; If the duration is less than or equal to the target duration threshold, then monitoring of the distance between the following vehicle and the vehicle itself, as well as the status of the high beams of the following vehicle, will cease. If the duration exceeds the target duration threshold, the distance between the following vehicle and the vehicle itself, as well as the status of the following vehicle's high beams, will be continuously monitored.

[0062] In this implementation, the stronger the high beam interference from the following vehicle is indicated by the high beam interference information, the more necessary it is to continuously monitor the following vehicle. Therefore, the target duration threshold needs to be smaller than the initial duration threshold. That is, the monitoring of the distance between the following vehicle and the vehicle itself, as well as the high beam status of the following vehicle, will only stop when the duration of the following vehicle's high beams is shorter.

[0063] The following example illustrates how to determine the target duration threshold based on the high beam interference impact information and the preset initial duration threshold, with reference to how to determine the target interference distance.

[0064] If the rainfall exceeds the preset rainfall threshold and / or the ambient humidity exceeds the preset humidity threshold, a third correction factor is determined, which is a preset value less than 1. When the non-vehicle headlight ambient light information meets the second strong interference condition, a fourth correction coefficient is determined, which is a preset value less than 1.

[0065] In this example, if only the third correction coefficient is determined, the target duration threshold is determined based on the product of the third correction coefficient and the initial duration threshold; if only the fourth correction coefficient is determined, the target duration threshold is determined based on the product of the fourth correction coefficient and the initial duration threshold; if both the third and fourth correction coefficients are determined, the target duration threshold is determined based on the product of the third correction coefficient, the fourth correction coefficient, and the initial duration threshold; otherwise, the target duration threshold is equal to the initial duration threshold.

[0066] The embodiments of the present invention determine a dynamic target duration threshold through the above steps to determine whether to continuously monitor the following vehicle, which is beneficial to achieving a balance between monitoring resources and driving safety.

[0067] To better understand the technical solution of the present invention, the present invention will be described below with reference to specific examples.

[0068] Assume that the driver, based on the influence of the high beams of the vehicle behind, sets the initial interference distances as follows: K1=60m, K2=120m, K3=150m, and sets the initial duration threshold T1=3s.

[0069] When the ambient light information (excluding vehicle headlights) does not meet the second strongest interference condition, and the rainfall is less than or equal to a preset rainfall threshold and the ambient humidity is less than or equal to a preset humidity threshold, the interference distance of each target is equal to the corresponding initial target interference distance, and the target duration threshold is equal to the initial duration threshold. If the visual sensor and the rearview mirror light sensor jointly detect that the following vehicle has its high beams on and the distance k between the vehicle and the following vehicle is greater than 150m, the system will continue to detect the status of the following vehicle (distance and high beam status). If the duration of the following vehicle's high beams is less than or equal to 3s, the tracking will stop. If the duration is greater than 3s, and the distance to the following vehicle decreases by 120m < k ≤ 150m, the central sensor outputs a command to the following vehicle's lights, and the following vehicle's lights display the message "Your high beams are causing slight visual interference to this vehicle, please keep your distance." When the following vehicle does not turn off its high beams and the distance continues to decrease (90m < k ≤ 120m), the central sensor sends a command to the following vehicle's lights, which display the message: "Your high beams are causing moderate visual interference to this vehicle; please maintain a safe distance." When the following vehicle does not turn off its high beams and the distance continues to decrease (60m < k ≤ 90m), the central sensor sends a command to the following vehicle's lights, which display the message: "Your high beams are causing severe visual interference to this vehicle; please turn off your high beams immediately." When the distance to the following vehicle continues to decrease to K ≤ 60m, the central sensor sends a command to the following vehicle's lights, which display the message: "Your high beams are causing severe visual interference to this vehicle; please turn off your high beams immediately." When the following vehicle cooperates by turning off its high beams, the vision sensor and the rearview mirror light sensor detect that the high beams are off, input the collected information into the central sensor, and the central sensor sends a command to the following vehicle's lights, displaying the message: "Visual interference resolved; thank you for turning off your high beams." When the following vehicle decelerates and controls the distance to K>150m, if the vision sensor and the rearview mirror light sensor detect that the following vehicle's high beams are off, the collected information will be input into the central sensor. The central sensor will then output a command to the following vehicle's lights, prompting the following vehicle that "visual interference has been eliminated and high beams can be turned on."

[0070] When the ambient light information outside the vehicle headlights meets the second strongest interference condition (for example, the light sensor on the roof detects that the ambient light intensity is lower than the set light-sensing threshold, and the vision sensor detects that there are no streetlights in the environment), the impact of the high beams is greater in this environment than when there are visible lights such as streetlights nearby. The system dynamically multiplies the initial interference distances K1, K2, and K3 by a second correction coefficient of 1.1 (a preset value greater than 1) to amplify and obtain the target interference distance K1. ′ =60 * ​​1.1 = 66m, K2 ′ =120 * 1.1 = 132m, K3 ′ =150*1.1=165m; and the initial duration threshold T1 will be dynamically multiplied by the fourth correction coefficient 0.95 (a preset value less than 1) to obtain the target duration threshold T1. ′=3 * 0.95 = 2.85s.

[0071] If the rainfall exceeds a preset rainfall threshold and / or the ambient humidity exceeds a preset humidity threshold, the system will dynamically multiply the initial interference distances K3, K2, and K1 by a first correction coefficient of 1.2 (a preset value greater than 1) to amplify the target interference distance K1. ′ =60 * ​​1.2 = 72m, K2 ′ =120 * 1.2 = 144m, K3 ′ =150*1.2=180m; and the initial duration threshold T1 will be dynamically multiplied by a third correction coefficient (a preset value less than 1) to obtain the target duration threshold T1. ′ =3 * 0.9 = 2.7s.

[0072] When the ambient light information of non-vehicle lights meets the second strong interference condition, and the rainfall is greater than the preset rainfall threshold and / or the ambient humidity is greater than the preset humidity threshold, the system will dynamically superimpose the initial interference distances K3, K2, and K1 and multiply them by the first and second correction coefficients to amplify and obtain the target interference distance K1. ′ =60*1.1*1.2=79.2m, K2 ′ =120*1.1*1.2=158.4m, K3 ′ =150*1.1*1.2=198m; and the initial duration threshold T1 will be dynamically multiplied by the third and fourth correction factors, T1 ′ =3*0.95*0.9=2.565s.

[0073] This invention, through comprehensive calculation and dynamic adjustment of the target interference distance affecting visibility, can provide more accurate high beam interference warnings. Combined with a light signal function, this invention can automatically switch light signals to alert following vehicles about high beam interference. When a following vehicle takes effective high beam interference control measures, this invention will again provide a positive thank-you message. Once the distance to the following vehicle has gradually increased and the adverse effects of re-enabling the high beams on this vehicle have disappeared, this vehicle will prompt the following vehicle to turn on its high beams to avoid prolonged periods of high beam deactivation that could impair the following vehicle's visibility and driving safety.

[0074] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

Figure 2 As shown, the exemplary high beam warning device includes: The acquisition module 210 is used to acquire information on the interference of high beams in the driving environment of the vehicle when it is detected that a vehicle behind has turned on its high beams. The first determining module 220 is used to determine N target interference distances based on the high beam interference impact information and the preset N initial interference distances; The second determining module 230 is used to determine whether the high beams of the rear vehicle interfere with the vehicle based on the distance between the rear vehicle and the vehicle itself and the N target interference distances; The first reminder module 240 is used to issue a high beam interference reminder message to the vehicle behind in the event of interference.
