The vehicle includes a high beam device 20, the high beam device 20 may include a vehicle high beam 22 and a high beam driver 21, the high beam driver 21 is electrically connected to the vehicle high beam 22, the high beam driver 21 is used to turn on and off the vehicle high beam 22, for example, a turn-on command and a turn-off command may be transmitted between the high beam driver 21 and the vehicle high beam 22 through CAN or hard wire.
The control device 10 may be connected to the high-beam driver 21 for controlling the high-beam device 20, for example, the on command and the off command may be transmitted between the control device 10 and the high-beam driver 21 via CAN or hard wire. The control device 10 is responsible for judging and analyzing the conditions for turning on or off the high beam 22 of the vehicle, and determining whether the high beam 22 of the vehicle needs to be turned on or off or not, the high beam driver 21 receives the command sent by the control device 10, the high beam 22 of the vehicle is turned on or off through the received corresponding command, and the road ahead is illuminated when the high beam 22 of the vehicle is turned on.
The first detecting device 31 is used for detecting the intensity of ambient light and transmitting the detected data to the control device 10, the first detecting device 31 is electrically connected to the control device 10, the first detecting device 31 can transmit the detected intensity data of the ambient light to the control device 10, and the first detecting device 31 can be a light sensor. Alternatively, the first detection device 31 may be provided at a front windshield of the vehicle body, a left side of the vehicle body, a right side of the vehicle body, or a top side of the vehicle body. Therefore, the first detection device 31 can conveniently detect the intensity of the ambient light, and the detection data is reliable.
For example, the signal may be transmitted between the first detection device 31 and the control device 10 via LVDS/CAN, which may be specific to the type of the first detection device 31 and the vehicle network. The first detecting device 31 is used to detect the intensity of the ambient light at which the vehicle is currently located, the first detecting device 31 transmits the detected intensity data of the ambient light to the control device 10, and the control device 10 can analyze and determine whether the current intensity of the ambient light meets the condition of turning on or off the high beam lamp 22 of the vehicle according to the intensity data of the ambient light. For example, when the ambient light is weak, if the user forgets or does not turn on the high beam lamp 22 in time, the control device 10 may control the high beam driver 21 to turn on the high beam lamp 22, so that the high beam lamp 22 system of the vehicle may turn on the high beam lamp 22 in time, thereby improving the driving safety at night; for another example, when the ambient light is strong, if the user forgets or does not turn off the high-beam vehicle lamp 22 in time, the control device 10 may control the high-beam driver 21 to turn off the high-beam vehicle lamp 22, so that the high-beam vehicle lamp 22 system can turn off the high-beam vehicle lamp 22 in time, which saves energy and avoids waste.
The second detecting device 32 is used for detecting the additional environmental parameter and transmitting the detected data to the control device 10, and the second detecting device 32 is connected with the control device 10 so as to transmit the additional environmental parameter detected by the second detecting device 32 to the control device 10. For example, the signal transmission between the second detection device 32 and the control device 10 may be performed through LVDS/CAN, which may be specific to the type of the second detection device 32 and the vehicle network. The additional environment parameters are detected by the second detection device 32 and transmitted to the control device 10, and the control device 10 analyzes and judges whether the current vehicle is suitable for turning on the vehicle high beam 22 according to the additional environment parameter data detected by the second detection device 32. If the ambient light is weak but the detected additional environmental parameters are not suitable for turning on the high beam 22 in combination with the detection result of the first detection device 31, turning off the high beam 22 and switching to the dipped beam; if the ambient light is weak and the detected additional ambient parameters are suitable for turning on the vehicle high beam 22, turning on the vehicle high beam 22; if the ambient light is strong, the vehicle high beam 22 is not turned on no matter whether the detected additional environmental parameters are suitable for turning on the vehicle high beam 22, and the vehicle high beam 22 is in a turn-off state at this time.
Alternatively, the second detection device 32 is provided at the front end of the vehicle body. Therefore, the second detection device 32 is convenient to detect the additional environmental parameters, and the detection data is reliable. For example, the second sensing device 32 may be provided on the front windshield, facilitating the second sensing device 32 to sense additional environmental parameters, and making the sensed data more reliable when the second sensing device 32 is provided at this location. Further, the position of the second detection device 32 on the front windshield may be disposed substantially opposite to the interior mirror of the vehicle in the front-rear direction.
Wherein the "additional environmental parameter" may include at least one of a traffic participant, a surrounding light source, and a climate environment. The traffic participants may include oncoming vehicles, pedestrians, riders, large animals, etc., the oncoming vehicles may be cars, trucks, etc., and the riders may include bicycles, motorcycles, electric motorcycles, etc. The peripheral light source may include a lamp of a vehicle traveling in opposite directions, a roadside light source, wherein the lamp may include a front light source of the vehicle (e.g., a headlight, a turn signal, a hazard light, and a traffic safety light) and a rear light source of the vehicle (e.g., a brake light, a turn signal, a traffic safety light), and the roadside light source may include a street light, a roadside building light, and the like.
When the second detection device 32 detects that there is a traffic participant in front of the vehicle, the control device 10 controls the high beam driver 21 to turn off the high beam 22, so as to avoid incorrect turning on of the high beam 22 and improve night driving safety. Since the high beam 22 can be turned off in time and can be switched to the low beam, the negative effect of strong light can be reduced, accidents caused by drivers who are not looking clearly at the front road can be prevented, and the occurrence probability of the accidents can be further reduced because the high beam 22 is turned off in time. It should be noted that the second detection device 32 can detect the traffic participants, such as vehicles traveling in the same direction, even if the vehicle lights are not turned on by the rider.
When the second detecting device 32 detects that there are peripheral light sources around the vehicle, even if the ambient light intensity detected by the first detecting device 31 is weak, since the peripheral light sources can improve the ambient light intensity for the vehicle, the vehicle high beam 22 may not be turned on at this time, the vehicle high beam 22 is turned off, and the low beam may be switched, so that unnecessary turning on of the vehicle high beam 22 may be avoided, and energy is saved. In addition, when the peripheral light sources are the lamps of the vehicles traveling in opposite directions, the control device 10 controls the high beam driver 21 to turn off the high beam 22, so that incorrect turning on of the high beam 22 can be avoided, and the driving safety at night can be improved. Since the high beam 22 can be turned off in time and can be switched to the low beam, the negative effect of strong light can be reduced, accidents caused by drivers who are not looking clearly at the front road can be prevented, and the occurrence probability of the accidents can be further reduced because the high beam 22 is turned off in time.
When the climate environment detected by the second detection device 32 is transmitted to the control device 10, and the control device 10 determines that the climate environment is good, the vehicle high beam 22 may be turned on when the intensity of the ambient light detected by the first detection device 31 satisfies the condition for turning on the vehicle high beam 22; when the control device 10 determines that the climate environment is severe, for example, the current climate environment is severe weather such as heavy rain, heavy snow, heavy fog, and sand storm, even if the intensity of the ambient light detected by the first detection device 31 satisfies the condition of turning on the high beam 22, the high beam 22 may be turned off, and the low beam may be switched.
For example, the control device 10 may control the high-beam driver 21 to turn on the vehicle high-beam 22 when the intensity of the ambient light detected by the first detection device 31 is lower than the set intensity and the additional environmental parameter detected by the second detection device 32 is suitable for turning on the vehicle high-beam 22; when the intensity of the ambient light detected by the first detection device 31 is not lower than the set intensity, the control device 10 may control the high-beam driver 21 to turn off the vehicle high-beam 22 or not turn on the vehicle high-beam 22; the control device 10 may control the high-beam driver 21 to turn off the vehicle high-beam 22 or not to turn on the vehicle high-beam 22 when the additional environmental parameter detected by the second detection device 32 is not suitable for turning on the vehicle high-beam 22. Wherein the set intensity may be 1 lux.
Further, when the ambient light intensity is lower than the set intensity for the set duration (for example, the set duration may be 2s) and the additional environmental parameter detected by the second detecting device 32 is suitable for turning on the vehicle high beam 22, the control device 10 may control the high beam driver 21 to turn on the vehicle high beam 22, and by detecting that the ambient light intensity is lower than the set intensity for the set duration as the detection data for determining the ambient light intensity, it may be possible to prevent a false determination, for example, a false determination that is likely to occur when the first detecting device 31 is blocked.
According to the vehicle high beam control system of the embodiment of the invention, the first detection device 31 for detecting the environmental light intensity can be used for conveniently detecting the environmental light intensity, so that the vehicle high beam 22 can be timely turned on or off according to the environmental light intensity, and the second detection device 32 for detecting additional environmental parameters can be used for timely turning off the vehicle high beam 22, so that the long-time unnecessary turning on of the vehicle high beam 22 is avoided, the energy is saved, the incorrect turning on of the vehicle high beam 22 can be avoided, and the night driving safety is improved.
According to some embodiments of the present invention, referring to fig. 1 and 2, the second detecting device 32 further includes a traffic participant detecting unit 321, and the traffic participant detecting unit 321 is configured to detect whether a traffic participant exists in front of the vehicle and transmit the detection data to the control device 10. When the second detection device 32 detects that there is a traffic participant in front of the vehicle, the control device 10 controls the high beam driver 21 to turn off the high beam 22, so as to avoid incorrect turning on of the high beam 22, thereby improving the driving safety at night. Since the high beam 22 can be turned off in time and can be switched to the low beam, the negative effect of strong light can be reduced, accidents caused by drivers who are not looking clearly at the front road can be prevented, and the occurrence probability of the accidents can be further reduced because the high beam 22 is turned off in time. When the second detection device 32 detects that there is no traffic participant in front of the vehicle, it can determine whether to turn on or turn off the vehicle high beam 22 by combining the ambient light intensity data detected by the first detection device 31, and when the ambient light intensity is weak (for example, the ambient light intensity is lower than the set intensity), the vehicle high beam 22 can be turned on, so as to improve the driving safety at night, and when the ambient light intensity is strong (for example, the ambient light intensity is not lower than the set intensity), the vehicle high beam 22 can be turned off or the vehicle high beam 22 is not turned on, so as to save energy. Wherein, the traffic participants can comprise vehicles, pedestrians, riders, large animals and the like which run in opposite directions, the vehicles which run in opposite directions can be automobiles, trucks and the like, and the riders can comprise bicycles, motorcycles, electric motorcycles and the like.
In some optional embodiments of the present invention, the transportation participant detecting unit 321 includes an image capturing module for capturing image information in front of the vehicle, and the control device 10 determines whether there is a transportation participant in front of the vehicle according to the image information in front of the vehicle. The image acquisition module may include a camera, and the image acquisition module may transmit the acquired image information to the control device 10, and the control device 10 may determine whether a traffic participant exists in front of the vehicle by analyzing the image information. Therefore, the second detection device 32 is configured to include an image acquisition module, so that image information in front of the vehicle can be conveniently acquired, and whether a traffic participant exists in front of the vehicle can be conveniently and accurately judged through the image information.
For example, the image acquisition module transmits the acquired image information to the control device 10, the control device 10 analyzes and judges the image information, if the contour shape is not found in the image information and the whole image is dark, it can be judged that no traffic participant exists in front of the current vehicle, and when the ambient light intensity is weak (for example, the ambient light intensity is lower than the set intensity), the vehicle high beam 22 can be turned on. When the image information includes shape information and the shape information is a target shape, specifically, when an outline shape is found on the image information and the outline shape is a target shape (for example, the target shape includes vehicles, pedestrians, riders, large animals, and the like traveling in opposite directions), it is determined that there is a traffic participant in front of the vehicle, the vehicle high beam 22 may be turned off and may be switched to the low beam, the vehicle high beam 22 is prevented from being turned on incorrectly, and the night driving safety is improved.
In his embodiment, the traffic participant detecting unit 321 may include a radar module, which may determine whether there is a traffic participant in front of the vehicle by transmitting an electromagnetic wave and receiving a feedback signal, and may calculate a distance between the traffic participant in front of the vehicle and the vehicle.

The peripheral light source may include a headlight of a vehicle, a roadside light source, and the like, which are moving in opposite directions, wherein the headlight may include a front light source (such as a headlight, a turn signal, a hazard light, and a traffic safety light) of the vehicle, and a rear light source (such as a brake light, a turn signal, and a traffic safety light) of the vehicle, and the roadside light source may include a street light, a road building light, and the like.
When the second detecting device 32 detects that there are peripheral light sources around the vehicle, even if the ambient light intensity detected by the first detecting device 31 is weak, since the peripheral light sources can improve the ambient light intensity for the vehicle, the vehicle high beam 22 may not be turned on at this time, the vehicle high beam 22 is turned off, and the low beam may be switched to, thereby avoiding unnecessary turning on of the vehicle high beam 22 and saving energy. In addition, when the peripheral light sources are the lamps of the vehicles traveling in opposite directions, the control device 10 controls the high beam driver 21 to turn off the high beam 22, so that incorrect turning on of the high beam 22 can be avoided, and the driving safety at night can be improved. Since the high beam 22 can be turned off in time and can be switched to the low beam, the negative effect of strong light can be reduced, accidents caused by drivers who are not looking clearly at the front road can be prevented, and the occurrence probability of the accidents can be further reduced because the high beam 22 is turned off in time. When the second detection device 32 detects that there is no peripheral light source in the periphery of the vehicle, it may determine whether to turn on or off the vehicle high beam 22 in combination with the ambient light intensity data detected by the first detection device 31, for example, when the ambient light intensity is weak (e.g., the ambient light intensity is lower than a set intensity), the vehicle high beam 22 may be turned on.
For example, the peripheral light source detection unit 322 may include an image acquisition module that transmits acquired image information to the control device 10. When the control device 10 determines that the brightness of the image is greater than the set brightness, it may determine that there are peripheral light sources around the vehicle, and when the peripheral light sources are the lamps of vehicles traveling in opposite directions, the high beam 22 may be turned off and switched to the low beam, so as to avoid incorrect turning on of the high beam 22, and improve the safety of driving at night; when the peripheral light source is a roadside light source, the high beam 22 can be turned off and switched to the dipped headlight, so that the high beam 22 is not required to be turned on, and energy is saved.
According to some embodiments of the present invention, referring to fig. 1 and 2, the second detection device 32 further includes a climate environment detection unit 323, and the climate environment detection unit 323 is configured to detect a climate environment in which the vehicle is currently located, and transmit the detection data to the control device 10. The climate environment detection unit 323 transmits the detected climate environment parameters to the control device 10, and when the control device 10 determines that the climate environment is good, the vehicle high beam 22 may be turned on when the ambient light intensity detected by the first detection device 31 satisfies the condition for turning on the vehicle high beam 22 (for example, when the ambient light intensity is lower than the set intensity); when the control device 10 determines that the climate environment is severe, for example, the current climate environment is severe weather such as heavy rain, heavy snow, heavy fog, and sand storm, even if the intensity of the ambient light detected by the first detection device 31 satisfies the condition of turning on the high beam 22, the high beam 22 may be turned off, and the low beam may be switched.
For example, the climate environment detection unit 323 may be electrically connected to at least one of the wiper blade 60 of the vehicle and the fog lamp device 70 of the vehicle to detect the climate environment in which the vehicle is currently located. When the weather environment detection unit 323 is electrically connected to the wiper 60 of the vehicle, the weather environment detection unit 323 can detect the state of the wiper 60, the state of the wiper 60 includes whether the wiper is in operation or not, the wiping frequency during operation, and the like, the weather environment detection unit 323 transmits the detected state data of the wiper 60 to the control device 10, and the control device 10 controls the vehicle high beam 22 according to the state of the wiper 60. For example, when the wiper 60 is in operation and the wiping frequency of the wiper 60 is greater than the set frequency, the control device 10 may determine that the weather at this time may be heavy rain or heavy snow, and the control device 10 controls the high beam driver 21 to turn off the high beam 22 and switch to the low beam, so as to improve the driving safety. When the climate environment detection unit 323 is electrically connected to the fog lamp device 70 of the vehicle, the climate environment detection unit 323 may detect the state of the fog lamp device 70, the state of the fog lamp device 70 includes whether the fog lamp device 70 is operating, and the like, the climate environment detection unit 323 transmits the detected state data of the fog lamp device 70 to the control device 10, and the control device 10 controls the vehicle high beam 22 according to the state of the fog lamp device 70. When the fog lights of the fog light device 70 are turned on, the control device 10 can determine that the weather at this time may be a heavy fog or sand-dust weather, and the control device 10 controls the high beam driver 21 to turn off the high beam 22 and switch to the dipped headlights, so as to improve the driving safety.
