Description

Technical Field

[0001] The present invention relates to the field of automobile intelligent control, and in particular to a system based on high beam recognition. Background Art

[0002] Low beam is mainly used for short-distance lighting during nighttime driving. Its design features a wide range of illumination and a relatively short illumination distance, providing drivers with a good short-range vision. High beam is used for long-distance road lighting in front of the vehicle. In areas with sufficient road lighting, low beam can generally meet the needs of nighttime driving. If high beam is used indiscriminately, it will affect oncoming cars. Drivers of oncoming cars will not be able to observe road conditions due to high beam, increasing driving risks.

[0003] Currently, there are many ways to prevent the indiscriminate use of high beams, such as automatic high beams. The car observes oncoming vehicles and controls the working status of the high beams. This can only meet the driving needs of oncoming vehicles. If the oncoming vehicle does not have this type of system installed and turns on the high beams indiscriminately, it will affect your own driving.

[0004] At present, camera recognition technology has become more and more mature and can be used to identify various types of objects. For example, the public document with application number 202222559223.4 and patent name "An Automatic Identification Camera" discloses an automatic identification camera, including: a protective shell, one end of the protective shell is fixedly connected to a face recognition probe, the upper part of the face recognition probe is provided with a first fill light, the interior of the protective shell is provided with a first mounting plate and a second mounting plate, the first mounting plate and the second mounting plate are respectively connected to the protective shell by bolts, and a connecting ear is welded on the upper part of the protective shell; the servo motor can drive the lead screw to rotate, so that the slider moves, and the lower part of the slider is fixedly connected to a garbage recognition probe, so that it can be used to shoot above multiple classified trash cans for detecting garbage in the trash cans, one end of the protective shell is fixedly connected to a face recognition probe, which is used to monitor people who throw garbage, and record and shoot, so that the people who throw garbage and the garbage they throw away correspond one by one, so as to achieve the purpose of identification and tracking.

[0005] If a high beam recognition alarm and reminder device combined with a camera can be developed, driving safety can be greatly improved. Summary of the invention

[0006] The technical problem to be solved by the present invention is to realize a high beam monitoring and reporting system through technical means such as technical reminders and reports, thereby reducing the current situation of illegal high beam use on the road and protecting the legitimate rights and interests of drivers.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a high beam recognition and reporting system, the system is provided with a camera for collecting front image information, and a distance sensor for collecting front obstacle distance information, the camera and the distance sensor are connected and output sensing signals to a processor, and the processor is connected to a communication module for sending reporting information to the outside.

[0008] The processor is connected to a central control screen, and the central control screen is configured for interaction, displaying the identified reporting information and whether to make a report.

[0009] The system is provided with a light intensity sensor for collecting the light intensity in front of the vehicle. The light intensity sensor is connected to and outputs a sensing signal to a processor. The light intensity sensor is surrounded by a trumpet-shaped light shield, which is fixed on the instrument panel. The larger opening of the light shield faces the front of the vehicle, and the light intensity sensor is fixed on the smaller opening of the light shield.

[0010] The system is provided with a reminder device for reminding the target vehicle to turn off the high beam, the reminder device includes a display screen arranged in front of the car, the processor is connected to and outputs a control signal to the reminder device, and the reminder device also includes a laser fixed on the electric pan head in front of the vehicle.

[0012] 1) System startup;

[0013] 2) The vehicle sensor senses whether the oncoming vehicle has turned on its high beam;

[0014] 3) When the target vehicle turns on the high beam, the camera is activated to collect evidence;

[0015] 4) Whether the central control screen interaction is reported;

[0016] 5) When the user chooses to report, the evidence information will be sent to the preset network interface. When the user chooses to cancel, or does not choose within the set time, the identification and reporting work will end.

[0017] In the above 1), after the vehicle is started, the time, weather and ambient light intensity information of the current location are obtained, and when the vehicle lighting needs to be turned on and the ambient brightness is lower than the set value, the system is started.

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is a brief description of the contents expressed in each figure in the specification of the present invention:

[0024] Figure 1 This is the schematic diagram of the high beam recognition reporting system. DETAILED DESCRIPTION

[0025] The following is a further detailed description of the specific implementation methods of the present invention, such as the shape, structure, relative position and connection relationship between the various components involved, the function and working principle of each part, the manufacturing process and operation method, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0026] The high-beam recognition reporting system collects the camera of the front image information and the distance sensor of the front obstacle distance information. The camera can adopt the road high-beam recognition camera currently used by vehicles. The camera on the vehicle can identify the license plate number of the target vehicle at close range and record the relevant evidence information in parallel to facilitate reporting. The distance sensor can adopt the existing body radar. The camera and the distance sensor are connected and output the sensing signal to the processor. The processor is used for data processing. The controller on the existing vehicle can be developed, and the processor function of this system can be used as one of the functions of the controller, thereby reducing the hardware cost.

[0027] In addition, the system can also connect to the vehicle's positioning unit, network unit, vehicle control unit, and central control screen to obtain the vehicle's location information, network weather forecast, vehicle current startup status and speed, and use the central control screen to interact with the system. The central control screen can also be used to pre-select the system's automatic execution standard and whether the system turns on this function. Violation conditions and penalty standards: The central control screen can prompt before each report is required, display the identified report information and whether to report, so that users can choose. Driving a motor vehicle on urban roads without using high beams as required or using high beams for a long time, meeting other vehicles, and not turning off high beams will be fined 200 yuan and deducted three points.

[0028] The system is equipped with a light intensity sensor. Two light intensity sensors can be set as needed. One uses ambient light intensity and can be used as a standard device to determine whether the system is started. For example, the system can be turned off during the day and when the light is good, and turned on at night. This can not only reduce the operating burden and reliability of the vehicle system, but also reduce the occurrence of false alarms. The other light intensity sensor collects the light intensity in front of the vehicle. The two light intensity sensors are connected and output sensing signals to the processor. The light intensity sensor that collects the light intensity in front of the vehicle is surrounded by a trumpet-shaped light shield. The light shield is fixed on the instrument panel and is preferably set in front of the driver's position. In this way, the position for collecting light intensity is consistent with the driver's position, and the light intensity information in front can be obtained more accurately. The light shield is an opaque cover, with the larger opening side facing the front of the car and the smaller opening side sealed. The light intensity sensor is fixed on this side of the light shield, so as to avoid the influence of light from other directions and only obtain the brightness information of the front high beam, so that the collection is more accurate and avoids misjudgment.

[0029] The system is provided with a reminder device for reminding the target vehicle to turn off the high beam. The processor is connected and outputs a control signal to the reminder device, which can warn the vehicle in front, reduce the number of reports, and give the other party a chance to remind and correct its mistakes. The reminder device includes a display screen arranged in front of the car. The display screen can be a headlight, a roof screen or a screen in the windshield. The reminder can display pre-selected recorded information, such as the prompt "Please turn off the high beam, otherwise I will report it, thank you". In addition to displaying the reminder, the reminder can also be given by irradiation. The reminder device also includes a laser arranged on an electric pan-tilt in front of the vehicle. The electric pan-tilt can control the irradiation angle of the laser, and can control the laser to irradiate the (high beam) light source. The light column is very conspicuous at night, so that oncoming vehicles can quickly notice the vehicle. Through irradiation reminders and text reminders, oncoming vehicles that turn on the high beam can immediately turn off the high beam. At the same time, the laser beam irradiates the high beam light source, and will not cause harm to oncoming vehicles and personnel. Not only is the reminder effect good, but it is also safe and controllable to use, with a strong sense of technology.

[0030] The data interaction between the above-mentioned positioning unit, network unit, vehicle control unit, central control screen, light intensity sensor, camera, distance sensor, reminder device and processor can use CAN communication for information transmission and command execution.

[0031] The reporting method based on the high beam recognition reporting system includes the following steps:

[0032] 1) System startup. The system is activated only when needed. The startup program can be preset. After the vehicle is started, the time, weather, and ambient light intensity information of the current location are obtained. When it is daytime and the weather is good, there is no need to perform high beam detection. When the current time and location are combined, if it is cloudy during the day or at night, the car lighting needs to be turned on and the ambient brightness is lower than the set value, the system is started, so that the system's working timing is controllable and intelligently turned on. Of course, whether this function is turned on can also be set on the central control screen. The factory setting is turned on;

[0033] 2) The vehicle sensor senses whether the oncoming vehicle has turned on the high beam. During the initial operation, only the light intensity sensor that collects the light intensity signal in front is turned on. With fewer working components, it can not only reduce energy consumption but also provide stability for the system. When the ambient brightness in front is higher than the minimum set threshold, the distance sensor is started to obtain the distance information of the obstacle. According to the relationship table between the set distance and brightness, it is checked to determine whether the high beam is turned on.

[0034] When it is turned on, when the vehicle is driving at night, the light sensor identifies the ambient light intensity and recommends the light intensity value;

[0035] Distance / m 0 50 100 150 Recommended light intensity / cd 0 25350 7831.25 3712.5

[0036] The distance sensor gives the distance of the target vehicle. When the distance sensor identifies that the oncoming vehicle is 150m, 100m, or 50m away from the driving vehicle, the light sensor controller can identify the current LX value and convert it into a cd value according to the formula Ev(lx)=I v(cd) / d(m)2 (the formula shows that the illuminance (lx) is equal to the luminous intensity (cd) divided by the square of the distance from the light source to the receiving surface (m^2), that is, 1lx=1cd / d(m)2). The program compares the set value to determine whether to use high beam (cd value measurements are performed at three distances of 150m-100m-50m to improve the accuracy of judgment).

[0037] 3) When there is a target vehicle with high beams on, the camera is activated to collect evidence. The camera is activated and locked onto the target obstacle graphic to determine whether the obstacle graphic is a car. This can further avoid false alarms. For example, if the speed light on the highway is too bright, the function may be triggered by mistake. If the outline of the luminous object is not a car, no operation is performed. If it is, photos or videos are taken to obtain evidence of the vehicle turning on the high beams and license plate information.

[0038] 4) The central control screen will interact with the driver to report whether to close the pop-up window or upload the other party's license plate number to report the other party's illegal use of high beams based on his own judgment of driving intention (the sensor confirms whether the target vehicle uses high beams, and the driver confirms whether the other party's use is illegal). The reminder device is activated while the prompt is being given, and the display screen displays the preset prompt. The electric gimbal rotates to make the laser shine on the high beam light source. When the laser is irradiated, the camera will also be used for correction. The camera also obtains the laser beam position information to determine whether it is irradiated on the determined high beam light source, and controls the gimbal in real time to adjust the laser's irradiation direction. By using the visual system for adjustment, the accuracy requirements for initial irradiation are reduced, and when the target car is moving, it can follow its high beam for irradiation to avoid the laser irradiating to other directions, avoiding unnecessary danger and injury;

[0039] 5) When the user chooses to report, the evidence information will be sent to the preset network interface. When the user chooses to cancel or does not choose within the set time, the identification and reporting work will be terminated. The evidence information includes photos or videos taken, shooting time information, and positioning information. When the report is executed or the identification and reporting work is terminated, the reminder device will be turned off.

[0040] This invention has two advantages:

[0041] 1. High beams cannot be used under some current working conditions. Illegal use of high beams poses a huge challenge to road safety;

[0042] 2. Currently, the relevant departments are unable to effectively investigate and control the illegal use of high beams. Equipping vehicles with such functions can effectively prevent such illegal operations from occurring.

[0043] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
