Description

Technical Field

[0001] The present invention relates to the technical field of vehicle headlights, and in particular, to a method for automatically controlling vehicle headlights and an apparatus for automatically controlling vehicle headlights. Background Art

[0002] Currently, there are generally two control methods for vehicle headlights: 1. After the user judges the environmental conditions by himself / herself, manually turn on or off; 2. After judging the environment through an in-vehicle light intensity sensor, automatically turn on or off.

[0003] For novice drivers lacking automotive knowledge, they often forget to turn on the headlights (the headlights include position lights or low beam lights). In some environments where the headlights should be turned on, if the position lights or low beam lights are not turned on in time to externally express the position outline of the vehicle and improve the visual experience of the driver of the vehicle, there is a risk of causing traffic accidents.

[0004] For the situation where the vehicle is not equipped with a light sensor or the vehicle light sensor is malfunctioning, currently, it is impossible to directly rely on the light intensity sensor to automatically turn on or off the headlights, which is not conducive to the driving safety of novice drivers and the experience of vehicle use convenience is not good.

[0005] Therefore, a solution that can provide automatic control services for turning on or off vehicle headlights for novice drivers without completely relying on the vehicle's own light sensor is needed, such as a solution that makes full use of vehicle networking technology and the data analysis ability of the cloud; to solve the problem that the vehicle's function of automatically turning on or off the headlights is limited by the sensor hardware conditions currently.

[0063] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0064] Figure 1 It is a flowchart of an automatic control method for vehicle headlights according to an embodiment of the present invention;

[0065] As Figure 1 shown, the headlights include position lights and / or low beam lights, and the method for automatically controlling the headlights includes:

[0066] Step S1, obtaining the position information and environmental information of the vehicle to be controlled;

[0067] Step S2, obtaining the headlight working information of the seed vehicles within a preset position area according to the position information of the vehicle to be controlled;

[0068] Step S3, generating working signals for the position lights and / or low beam lights of the vehicle to be controlled according to the headlight working information of the seed vehicles and the environmental information of the vehicle to be controlled.

[0069] Specifically, the selection of seed vehicles has flexible criteria, depending on how it is more beneficial to assist the vehicle to be controlled. For example, select the vehicles driven by drivers with a driving mileage of more than 30,000 kilometers and a driving age of more than 5 years as seed vehicles. Such drivers have rich driving experience, have a good understanding of the functions of the vehicle, and the vehicles they control are exemplary. For another example, select vehicles with advanced sensors as seed vehicles. Such users have good hardware equipment and efficient and accurate information. For another example, select vehicles with an information subscription relationship with a third-party data platform as seed vehicles. Such users have a wider information source and can obtain a wider and more advanced light illuminance-related information source. The selection of seed vehicles can be a single criterion or a mixed selection criterion.

[0070] In this embodiment, obtaining the headlight working information of the seed vehicles within a preset position area according to the position information of the vehicle to be controlled includes:

[0071] Obtaining the seed vehicle position information transmitted by each seed vehicle;

[0072] Obtaining a preset position area according to the position information of the vehicle to be controlled;

[0073] According to the position information of each seed vehicle, obtaining the headlight working information of the seed vehicles whose seed vehicle position information is within the preset seed vehicle acquisition range.

[0074] Specifically, the position relationship information between vehicles is obtained through the GPS positioning information of the vehicle to be controlled and the seed vehicles; select a vehicle to be controlled and set a preset position area for it. For example, with the vehicle to be controlled as the center, a preset position area is set with a radius of 3KM. The seed vehicles in this area have a lighting environment similar to that of the vehicle to be controlled, and the headlight working information of these seed vehicles can be obtained as a reference. For example, whether the headlights of the seed vehicles are on or off, how many seed vehicles have their headlights on, and how many seed vehicles have their headlights off, etc.

[0075] Obtaining the headlight working information of the seed vehicles within the range can be achieved by directly using the headlight control status information of the seed vehicles, or indirectly by using the information of the light intensity sensors of the seed vehicles to replace the headlight control status information of the seed vehicles.

[0076] Specifically, through vehicle networking technology and the data analysis capabilities of the cloud, the information of the vehicle to be controlled and the seed vehicles can be associated, and information processing can be carried out around the vehicle to be controlled.

[0077] In this embodiment, the environmental information of the vehicle to be controlled includes light intensity information and the light intensity confidence information corresponding to the light intensity information;

[0078] Controlling the position lights and / or low beam lights of the vehicle to be controlled according to the headlight working information of the seed vehicles and the environmental information of the vehicle to be controlled includes:

[0079] Obtain the external light intensity information of the vehicle to be controlled and the light intensity confidence information corresponding to the light intensity information;

[0080] Obtain the headlight working information of each seed vehicle located in the preset position area;

[0081] Obtain the headlight-on confidence within the area and the headlight-off confidence within the area according to the headlight working information of each obtained seed vehicle located in the preset position area;

[0082] Generate the working signals of the position lights and / or low beam lights of the vehicle to be controlled according to the external light intensity information of the vehicle to be controlled, the light intensity confidence information corresponding to the light intensity information, and the headlight control confidence within the area.

[0083] Specifically, there may be information deviation in understanding the light intensity at the location of the vehicle to be controlled only through the light intensity sensor carried by the vehicle itself. It is necessary to obtain more extensive light intensity information as a reference, but it cannot be separated from the vehicle to be controlled. For example, it is possible to obtain the status information generated by the headlights of other seed vehicles in the preset position area around the vehicle to be controlled, which is similar to that of the vehicle to be controlled. However, when the number of reference seed vehicles is too small and the seed vehicles are too far away from the vehicle to be controlled, the collected information has low reference value, and it is necessary to preset the minimum number threshold and the preset position area of the vehicle to be controlled.

[0084] The headlight status information of each seed vehicle is not necessarily exactly the same. Some are on and some are off. It is necessary to determine which headlight control status is more credible according to the number of seed vehicles with different headlight control statuses. For example, if the number of seed vehicles with their headlights on is dominant, the vehicle to be controlled should turn on its own headlights.

[0085] Convert the headlight status information of a large number of seed vehicles into confidence information to assist the vehicle to be controlled in controlling the headlights.

[0086] The reason why the light intensity information of the vehicle to be controlled itself corresponds to the light intensity confidence information corresponding to this light intensity information is that a preset position area for obtaining the information of the seed vehicles is set according to the location of the vehicle to be controlled, and the generation of the light intensity confidence information all comes from the seed vehicles in this preset position area.

[0087] In this embodiment, generating the working signal of the position light and / or low beam light of the vehicle to be controlled according to the external light intensity information of the vehicle to be controlled, the light intensity confidence information corresponding to this light intensity information, and the headlight control confidence in the area includes:

[0088] Judge whether the external light intensity information of the vehicle to be controlled is within the first light intensity area. If so, then

[0089] Judge whether the light intensity confidence corresponding to the first light intensity area is greater than the first confidence threshold. If so, then,

[0090] Generate the turn-on working signal of the position light and / or low beam light of the vehicle to be controlled.

[0091] Specifically, an instruction to turn on the headlamp of the vehicle to be controlled can be generated by means of two judgment conditions. For example, the light intensity sensor information of the vehicle to be controlled itself is used as the first judgment basis to determine whether the light is insufficient at its location, and the light intensity confidence information corresponding to the location of the vehicle to be controlled is used as the second judgment condition to indicate whether the credibility of each of the other seed vehicles choosing to turn on the headlamp is high enough. When the two pieces of information are consistent, the vehicle to be controlled can generate a signal to turn on the headlamp.

[0092] Of course, the first light intensity area should also be set reasonably and needs to meet general quantitative judgment requirements.

[0093] In this embodiment, generating the working signal of the position lamp and / or low beam of the vehicle to be controlled according to the external light intensity information of the vehicle to be controlled, the light intensity confidence information corresponding to the light intensity information, and the headlamp control confidence within the area includes:

[0094] Judge whether the external light intensity information of the vehicle to be controlled is within the second light intensity area. If so, then

[0095] Judge whether the light intensity confidence corresponding to the second light intensity area is greater than the second confidence threshold. If so, then,

[0096] Generate the closing working signal of the position lamp and / or low beam of the vehicle to be controlled.

[0097] Specifically, it is similar to the principle that the vehicle to be controlled can generate a signal to turn on the headlamp above, and both can control the headlamp by combining two judgment conditions.

[0098] As long as the limiting conditions such as reasonable light intensity areas, confidence thresholds, and preset position areas are set, generating the opening and closing working signals of the position lamp and / or low beam of the vehicle to be controlled can serve novice drivers well.

[0099] Specifically, the preset position area should not be too large or too small because there are certain differences in the lighting environments of the vehicle to be controlled and the seed vehicles at different times and on different road sections. For example, there are significant differences in the lighting environments of vehicles in the suburbs and in the city center. In suburban road sections, the street lamp density is low, there is a lack of other light source supplements, the vehicle density is also low, and the formed lighting environment is relatively dark. Moreover, the vehicle speed may be relatively high, and in terms of confidence information, it is more necessary to turn on the headlamp in advance, especially to increase the probability of using the low beam; while in the city center, in addition to the dense street lamps, there are also other buildings, billboards, decorative lights, and other dense vehicles that together form a relatively bright lighting environment. Moreover, the vehicle speed may be relatively low, and in terms of confidence information, it is more inclined to turn on the position lamp only; if the preset position area is too large, the confidence information may be contaminated. For example, it may cause the vehicle to be controlled to only turn on the position lamp in a relatively harsh lighting environment such as in the suburbs, without playing a role in improving vehicle driving safety, while in the city center with dense vehicles, the headlamp is over-activated, resulting in excessive light pollution.

[0100] In this embodiment, generating the working signal of the position lamp and / or low beam of the vehicle to be controlled according to the external light intensity information of the vehicle to be controlled, the light intensity confidence information corresponding to the light intensity information, and the confidence of the headlamp control in the area further includes:

[0101] Judging whether the following conditions are simultaneously satisfied:

[0102] The light intensity confidence corresponding to the first light intensity area is less than the first confidence threshold;

[0103] The confidence of turning on the headlamp in the area is greater than the confidence of turning off the headlamp in the area, and the number of seed vehicles is greater than the first preset number of seed vehicles;

[0104] If satisfied, generate the turn-on working signal of the position lamp and / or low beam of the vehicle to be controlled.

[0105] Specifically, the sensor information source of the vehicle to be controlled is relatively single, and is more mutation-prone compared to the light intensity confidence information. For example, when the oncoming vehicle's headlamp shines, causing the value of the light intensity sensor information to increase, or when the light intensity sensor is damaged, the value of the light intensity sensor information remains fixed or jitters irregularly. The confidence information obtained by referring to more seed vehicle samples is more credible than the light intensity sensor information obtained by referring to a single vehicle to be controlled sample.

[0106] In this embodiment, generating the working signal of the position lamp and / or low beam of the vehicle to be controlled according to the external light intensity information of the vehicle to be controlled, the light intensity confidence information corresponding to the light intensity information, and the confidence of the headlamp control in the area further includes:

[0107] Determine whether the following conditions are simultaneously satisfied:

[0108] The light intensity confidence level corresponding to the second light intensity region is less than the second confidence threshold;

[0109] The confidence level of the headlight being on within the determination region is less than the confidence level of the headlight being off within the region, and the number of seed vehicles is greater than the first preset number of seed vehicles;

[0110] If satisfied, generate a turn-off working signal for the position light and / or low beam of the vehicle to be controlled.

[0111] Specifically, similarly, the confidence information obtained by referring to more seed vehicle samples is more credible than the light intensity sensor information obtained by referring to a single vehicle to be controlled sample, and can also be used to generate a turn-off working signal for the position light and / or low beam of the vehicle to be controlled.

[0112] Although the untimely turning on of the headlight affects the driving safety of the vehicle, the untimely turning off of the headlight is also not conducive to the driving safety of the vehicle.

[0113] For example, in the city center, in addition to vehicles, there are also pedestrians. Excessive use of headlights has a serious impact on the line of sight of pedestrians. Especially, many vehicles equipped with low beams have abandoned halogen lamps and instead use LED lamps with extremely strong penetration. When a large number of dense vehicles turn on their headlights, it creates light pollution, interferes with the line of sight of nearby pedestrians, affects road safety, and harms the visual health of pedestrians.

[0114] In this embodiment, the light intensity information is obtained by a light intensity sensor provided on the vehicle.

[0115] Specifically, there are many ways to obtain and express the light intensity information. For example, the light intensity information obtained through weather forecast information, navigation information, and time clock information is more forward-looking and extensive. However, whether the light intensity information is obtained through the light intensity sensor of the vehicle to be controlled itself or through the light intensity sensors of other seed vehicles obtained from the cloud, it is more direct and accurate.

[0116] Due to the influence of factors such as weather, route, tunnel, landscape, and time period, when limited to a specific vehicle to be controlled, the direct light intensity information is more effective than the indirect light intensity information.

[0117] In this embodiment, the following method is used to obtain the light intensity confidence information:

[0118] Obtaining the light intensity information of the location where the vehicle to be controlled is located includes:

[0119] Obtain the light intensity information transmitted by the light intensity sensor of the vehicle to be controlled as the light intensity information at the location of the vehicle to be controlled; or,

[0120] Obtain the light intensity information transmitted by various sub-vehicle light intensity sensors within the preset position area of the vehicle to be controlled, and obtain the average value information as the light intensity information at the location of the vehicle to be controlled based on the light intensities of each sub-vehicle;

[0121] Set the first light intensity area condition and the second light intensity area condition;

[0122] Obtain the number of light intensity information that meets the first light intensity area condition and the number of light intensity information that meets the second light intensity area condition among the light intensity information transmitted by the light intensity sensor of the vehicle to be controlled and the light intensity sensors of each sub-vehicle within the preset position area;

[0123] Divide the number of light intensity information that meets the first light intensity area condition by the sum of the light intensity information transmitted by the light intensity sensor of the vehicle to be controlled and the light intensity sensors of each sub-vehicle within the preset position area, so as to obtain the light intensity confidence corresponding to the first light intensity area;

[0124] Divide the number of light intensity information that meets the second light intensity area condition by the sum of the light intensity information transmitted by the light intensity sensor of the vehicle to be controlled and the light intensity sensors of each sub-vehicle within the preset position area, so as to obtain the light intensity confidence corresponding to the second light intensity area.

[0125] Specifically, obtaining the confidence information of the light intensity depends on reference samples with high credibility and a sufficient number of reference samples.

[0126] For example, in an embodiment, the vehicle to be controlled does not have a light intensity sensor. At this time, the average value is obtained from the light intensity information transmitted by various sub-vehicle light intensity sensors within the preset position area of the vehicle to be controlled. For example, there are 5 sub-vehicles within the preset position area of this vehicle, and the light intensity information transmitted by the light intensity sensors of these 5 sub-vehicles are 1000, 1100, 1050, 1080, and 1070 respectively. By calculating 1000 + 1100 + 1050 + 1080 + 1070 = 5300, 5300 / 5 = 1060. That is, 1060 is used as the light intensity information at the location of the vehicle to be controlled.

[0127] In this embodiment, the first light intensity area condition is [1200Lux, 1500Lux],

[0128] The condition for the second light intensity region is that the confidence level for a light intensity value ≥ 2000 Lux is Cv2.

[0129] In this embodiment, the number of pieces of light intensity information that meet the first light intensity region condition and the number of pieces of light intensity information that meet the second light intensity region condition are obtained from the light intensity information transmitted by the light intensity sensor of the vehicle to be controlled and the light intensity information transmitted by the light intensity sensors of each seed vehicle within the preset position area. For example, the number of each seed vehicle within the preset position area is 99, and among them, the light intensity information of 90 vehicles meets the first light intensity region condition.

[0130] Add the number of the vehicle to be controlled + the number that meets the first light intensity region condition, that is, 91.

[0131] Divide the number of pieces of light intensity information that meet the first light intensity region condition by the sum of the light intensity information transmitted by the light intensity sensor of the vehicle to be controlled and the light intensity information transmitted by the light intensity sensors of each seed vehicle within the preset position area.

[0132] That is, divide 91 by 100 (the vehicle to be controlled + 99 seed vehicles) to get 0.91, and multiply 0.91 by 100%, that is, 91% is obtained as the light intensity confidence level.

[0133] In this embodiment, the confidence level for the headlight turn-on within the area is obtained according to the headlight working information of each acquired seed vehicle located in the preset position area by the following method:

[0134] In this embodiment, the headlight working information of the seed vehicle includes the confidence level for the accurate operation of the position light of each vehicle. This confidence level can be provided by the user of the seed vehicle himself. For example, through a man-machine interaction method, the user gives the confidence level result to the cloud by himself. For example, if the user inputs 1, it is considered that the confidence level is 100%, and if the user inputs 0.95, it is considered that the confidence level is 95%. In addition, it can also be obtained by other methods.

[0135] Taking the target vehicle position as the center, a radius of 3 km is used as the preset position area. The number of seed users within the range is n, and the serial numbers are 1, 2... n. Among them, the serial numbers of the users who turn on the position lights are 1, 2... m, and the serial numbers of the users who do not turn on the position lights are m + 1, m + 2... n. The confidence levels for the accurate operation of the position lights of each user are: C1, C2... Cm, Cm + 1... Cn.

[0136] C open (Confidence level for headlight turn-on within the area) = C1 + C2 +... + C m

[0137] C close (Confidence level of the front headlight off within the area) = C m+1 + C m+2 + …… + C n 。

[0138] In one embodiment, the following method is adopted to generate the working signal of the position light and / or low beam of the vehicle to be controlled according to the front headlight working information of the seed vehicle and the environmental information of the vehicle to be controlled:

[0139]

[0140] For the control of the low beam, it is the same as the control logic of the position light in the above table. Only the judgment range of the light intensity is different. Replace the content of serial number "1)" in the above table with the following description, that is, "Judge the environmental information: the confidence level that the light intensity value in the area where the target vehicle is located ≤ 800 Lux is Cv1; the confidence level that the light intensity value ≥ 1300 Lux is Cv2", and other contents are the same as the position light control.

[0141] Regarding each seed vehicle object with a reasonable number of seed vehicles, reasonable light intensity area conditions, and reasonable preset position areas as samples for obtaining the confidence level of the light intensity of the corresponding vehicle to be controlled, the obtained confidence level of the light intensity has a "compound eye" effect, reducing the influence of the mutation of the light intensity information of a certain vehicle individual on the confidence level of the "overall" light intensity information. At the same time, the service object of the "overall" light intensity information is unique for a certain vehicle to be controlled.

[0142] Figure 2 It is the structure diagram of the device for automatically controlling the vehicle headlight according to an embodiment of the present invention;

[0143] As Figure 2 shown, the device for automatically controlling the vehicle headlight includes: an information acquisition module, a working signal module;

[0144] The information acquisition module is used to acquire the position information and environmental information of the vehicle to be controlled;

[0145] The working information module is used to acquire the front headlight working information of the seed vehicle within the preset position area according to the position information of the vehicle to be controlled;

[0146] The working signal module is used to generate the working signal of the position light and / or low beam of the vehicle to be controlled according to the front headlight working information of the seed vehicle and the environmental information of the vehicle to be controlled.

[0147] It should be noted that although only the information acquisition module, work information module, and work signal module are disclosed in this system, it does not mean that the composition of this system is limited to the above basic functional modules. On the contrary, what the present invention intends to express is that based on the above basic functional modules, those skilled in the art can arbitrarily add one or more functional modules in combination with the prior art to form an infinite number of embodiments or technical solutions. That is to say, this system is open rather than closed, and it cannot be considered that the protection scope of the claims of the present invention is limited to the disclosed basic functional modules just because only individual basic functional modules are disclosed in this embodiment. At the same time, for the convenience of description, when describing the above device, it is divided into various units and modules according to functions for separate description. Of course, when implementing this application, the functions of each unit and module can be implemented in the same or multiple software and / or hardware.

[0148] Figure 3 It is a module architecture diagram of information interaction between a vehicle to be controlled and a cloud server for a specific embodiment of the present invention, and discloses a solution for obtaining vehicle information and environmental illumination information of the vehicle through a cloud server, and selecting a vehicle to be controlled for headlight control. In this embodiment, the cloud server assists in generating a command for controlling the headlight of the vehicle to be controlled by referring to the current on or off state of the headlight of the seed vehicle in a preset position area, and the vehicle to be controlled has the function of selecting whether to be automatically controlled for the headlight.

[0149] As Figure 3 shown, in this embodiment, vehicles meeting preset conditions are selected as seed vehicles; the working state of the headlight of the seed vehicle and the vehicle position information are uploaded to the cloud server in real time;

[0150] The cloud server can obtain the position information of the vehicle to be controlled in real time, obtain the light intensity information at the position where the vehicle to be controlled is located, the position information and the headlight working state information of the seed vehicle in a preset position area around the vehicle to be controlled.

[0151] In this embodiment, the source of the light intensity information includes not only the information of the light intensity sensor but also the environmental illumination information of each administrative region in the service of the weather information service provider, etc.

[0152] The vehicle to be controlled includes two functional modules, namely TBOX and BCM.

[0153] TBOX is used to communicate with the cloud server, report the position information of the vehicle to be controlled, receive the control command for the headlight of the vehicle to be controlled from the cloud server, and forward the headlight control command from the cloud to BCM;

[0154] BCM is used to control the vehicle headlight and monitor the working state of the vehicle to be controlled;

[0155] The BCM receives the headlight control command from the cloud server forwarded by the TBOX. However, it does not directly control the headlights. Instead, it first collects the gear switch status of the headlights.

[0156] The gear switch of the headlights has two mutually exclusive gears: manual control and automatic control.

[0157] When the BCM collects the information that the gear switch of the headlights is in the automatic control gear, the vehicle to be controlled is allowed to receive the headlight control command from the cloud server forwarded by the TBOX, and automatic control of the vehicle's headlights is allowed.

[0158] When the BCM collects the information that the gear switch of the headlights is in the manual control gear, the vehicle to be controlled is not allowed to receive the headlight control command from the cloud server forwarded by the TBOX, and automatic control of the vehicle's headlights is not allowed.

[0159] Among them, the automatic opening and closing of the headlights are controlled by the drive of the BCM.

[0160] The instrument can display the lighting working status information of the headlights.

[0161] Figure 4 It is the timing diagram of the headlight turning-on process of the vehicle to be controlled with a selection function in a specific embodiment of the present invention. A solution is disclosed in which, based on the gear of the current gear switch of the headlights, it is selected whether the vehicle becomes a vehicle to be controlled, enters the working mode of automatically controlling the headlights, and the headlights of the vehicle to be controlled are controlled by the cloud server.

[0162] As Figure 4 shown, in this embodiment, the cloud server subscribes to the position light and low beam status information and the position of the seed vehicle.

[0163] When the BCM of the current vehicle receives that the headlight switch is switched to the automatic gear, the current vehicle is allowed to subscribe to the headlight automatic control service from the cloud server through the TBOX and send the position information of the vehicle to be controlled to the cloud server. At this moment, the current vehicle becomes a vehicle to be controlled.

[0164] The cloud server filters the seed vehicles within the preset position area and the position light and low beam status information of the seed vehicles according to the position information of the vehicle to be controlled. The headlights include position lights and low beams.

[0165] The cloud server subscribes to the light intensity information service of each administrative region according to the position information of the vehicle to be controlled, such as weather forecast information, to obtain more environmental illumination information of the vehicle to be controlled.

[0166] The cloud server generates a command to control the headlamp of the vehicle to be controlled based on the preset headlamp control decision, the ambient illumination information of the location where the vehicle to be controlled is located, and the current on / off state information of the headlamps of each seed vehicle.

[0167] The cloud server sends the headlamp control command of the vehicle to be controlled to the vehicle to be controlled through the TBOX of the vehicle to be controlled.

[0168] The BCM of the vehicle to be controlled first determines whether the current on / off state of the headlamp of the vehicle to be controlled is consistent with the content of the headlamp control command sent by the cloud. If not, it executes the headlamp control command sent by the cloud server and refreshes the current on / off state of the headlamp of the vehicle to be controlled.

[0169] Among them, the headlamp control decision includes participating in generating confidence information through the on / off state information of the headlamps of the seed vehicles, including participating in generating confidence information through the information of the light intensity sensors of each vehicle, including participating in generating confidence information through third-party channel information, such as subscribing to the light intensity information service of each administrative region, and using the confidence information to generate a control command for the headlamp of the vehicle to be controlled.

[0170] The present invention has the following advantages compared with the prior art:

[0171] (1) This application realizes the purpose of not completely relying on the light intensity sensor of the vehicle to be controlled itself to obtain the light intensity information of the location where the vehicle to be controlled is located, making the judgment basis of the light intensity information of the location where the vehicle to be controlled is located richer.

[0172] (2) This application converts the light intensity information of the locations of the vehicle to be controlled and each seed vehicle within the preset position area into confidence information, reducing the possibility of signal mutation of the control headlamp of the vehicle to be controlled caused by sudden change of the sensor data of a certain vehicle.

[0173] (3) This application can utilize the light intensity information obtained from multiple channels to assist the vehicle to be controlled in getting rid of the dependence on its own light intensity sensor, enabling the vehicle to be controlled without a light intensity sensor to also obtain relatively reliable automatic headlamp control service.
