Abstract

This frost detection providing device for detecting a frost state of a vehicle lamp determines daytime, in-tunnel, and evening periods by using differences of a brightness sensor, irradiates a generated frost-detecting wavelength from a green LED to the vehicle lamp, and compares a green brightness light receiving value of an RGB sensor, measured by receiving light reflected from the vehicle lamp, with a reference intensity value of a green wavelength band measured by the RGB sensor preset for each period so as to detect the frost state of the vehicle lamp, thereby increasing the frost detection performance. According to the present invention, the frost detection performance may be improved by using a difference between a luminance receiving value of a luminance sensor, measured by using external light or ambient brightness, and a reference intensity value of the green wavelength band measured by the RGB sensor preset for each of the daytime, in-tunnel, and evening periods.

Description

A vehicle lamp sex detection device that detects sex

[0001] The present invention relates to a frost detection device for detecting vehicle lamp frost, and more particularly, to a frost detection device for detecting vehicle lamp frost, which recognizes daytime, tunnel, and evening sections by utilizing the difference in a brightness sensor, and detects the frost state of a vehicle lamp by comparing a wavelength for detecting frost generated from a green LED to a vehicle lamp, a green brightness reception value of an RGB sensor measured by receiving light reflected from the vehicle lamp, and a reference intensity value of a green wavelength band measured by an RGB sensor preset for each section, thereby detecting the frost state of a vehicle lamp and improving frost detection performance.

[0002] Typically, if a vehicle is left with the engine off for a long period of time during the winter, frost will form on the glass due to the temperature difference between the inside and outside of the vehicle.

[0003] Additionally, a film of ice (hereinafter referred to as “frost”) may form on glass due to frost or snow accumulation caused by water vapor in the atmosphere freezing on the glass.

[0004] These types of frost can be a driving hazard that makes it difficult for the driver to secure a clear view, so frost must be removed before driving to secure the driver's view.

[0005] Meanwhile, the conventional method of removing frost on glass involves turning on the vehicle engine and allowing the vehicle to warm up sufficiently for a certain period of time, then removing the frost through convection of engine heat using the air conditioning unit and conduction of a defogger, or the driver has to scrape it off manually.

[0006] The method of using hot or cold air is a technology that removes frost from the glass by blowing hot or cold air generated from the vehicle's air conditioning unit toward the glass through the air vents.

[0007] The method of using hot or cold air has limitations in that it is mainly limited to the front windshield of a vehicle, and the engine must be driven for the air conditioning system to operate, and the air conditioning fan must be driven together with the air conditioning system, which has the disadvantage of causing noise.

[0008] Additionally, there is a disadvantage in that after the vehicle is started and the engine has been warmed up for a certain period of time, hot or cold air of a temperature suitable for removing the odor is generated.

[0009] If it is not the windshield of the vehicle or a non-vehicle glass surface, it may be difficult to remove the frost, which can be a hassle as you may have to wait a long time.

[0010] If frost on a vehicle could be detected in advance, various measures could be taken, such as covering the windshield or moving the vehicle underground. However, currently, there is no method for detecting frost on a vehicle.

[0011] The present invention provides a vehicle lamp frost detection device that can detect the frost of a vehicle lamp by recognizing day, tunnel, and evening sections using the difference in a brightness sensor, and detecting the frost state of a vehicle lamp by comparing the green brightness reception value of an RGB sensor measured by receiving light reflected from the vehicle lamp and the green wavelength for detecting frost generated from a green LED with the reference intensity value of the green wavelength band measured by the RGB sensor set for each section, thereby improving the frost detection performance.

[0012] In order to achieve the above object, a vehicle lamp performance detection device according to the features of the present invention is provided.

[0013] A luminance sensor that measures the luminance value, which is the amount of light reflected from a target surface depending on external light or ambient brightness;

[0014] An RGB sensor that receives external light or ambient brightness with a photodiode and outputs RGB data containing intensity data of each color of red, green, and blue of the incident light;

[0015] Green LED that generates a wavelength for detection in the castle and irradiates it with a vehicle lamp; and

[0016] A microprocessor is included to determine whether it is a day section, an evening section, or a tunnel section by comparing a luminance reception value (A) of a luminance sensor measured by ambient brightness with a preset daytime reference luminance value (D) measured by ambient brightness when it is daytime, and a tunnel reference luminance value (T) of a preset luminance sensor measured by ambient brightness when it is a tunnel, and to detect a frost state of the vehicle lamp by comparing a green brightness reception value (G(n)) of the RGB sensor measured by receiving light reflected from the vehicle lamp with a sensor reception level of a reference intensity value of a green wavelength band measured by the RGB sensor preset for each section.

[0017] By the above-described configuration, the present invention has the effect of improving the performance of detecting sex by utilizing the difference between the luminance reception value of the luminance sensor measured by external light or ambient brightness and the reference intensity value of the green wavelength band measured by the RGB sensor set in advance for each day, tunnel, and evening section.

[0018] The present invention has the effect of further improving the accuracy of detecting the sex state by judging the sex state of a transparent lens while increasing the stage of the sex state.

In order to facilitate an overall understanding in describing the present invention, identical reference numerals will be used for identical components in the drawings, and redundant descriptions of identical components will be omitted.

[0028] Hereinafter, a vehicle lamp performance detection device for detecting performance according to one embodiment of the present invention will be described with reference to the attached drawings.

[0029] FIG. 1 is a drawing showing the configuration of a vehicle lamp performance detection device according to an embodiment of the present invention, FIG. 2 is a drawing showing the position of a green LED according to an embodiment of the present invention, and FIGS. 3 to 6 are drawings showing a method for detecting vehicle lamp performance according to an embodiment of the present invention.

[0030] A vehicle lamp performance detection device (100) according to an embodiment of the present invention includes a brightness sensor (110), a first analog-to-digital converter (111), an RGB sensor (120), a second analog-to-digital converter (121), an I2C Interface (122), a Green LED (130), a frequency generator (131), and a microprocessor (140).

[0031] The brightness sensor (110) performs the function of measuring the brightness level of the surroundings and can be used to detect the ambient lighting level.

[0032] The brightness sensor (110) detects the degree of glare from external light (such as the sun) or ambient light (such as an LED) and the brightness value, which is the amount of light reflected from the target surface.

[0033] The first analog-to-digital converter (111) converts the luminance value received from the luminance sensor (110) from analog to digital.

[0034] The first analog-to-digital converter (111) converts the analog signal collected from the brightness sensor (111) into digital information, and transmits the digitalized information to the microprocessor (140).

[0035] The RGB sensor (120) can measure the intensity of red, green, and blue light.

[0036] The RGB sensor (120) receives external light (such as the sun) or ambient light with a photodiode, measures the intensity of the red, green, and blue wavelengths of the incident light, and outputs RGB data including intensity data of each color of red, green, and blue of the measured light.

[0037] The RGB sensor (120) outputs RGB data in which each of R, G, and B has a value in the range of 1 to 65535.

[0038] The RGB sensor (120) may be a model such as TCS34725 that can measure a color temperature between 1000K and 7000K.

[0039] The second analog-to-digital converter (121) converts RGB data measured from the RGB sensor (120) from analog to digital.

[0040] The second analog-to-digital converter (121) converts the analog signal collected from the RGB sensor (120) into digital and transmits it to the microprocessor (140).

[0041] The I2C Interface (122) is a communication interface for exchanging data with other components, and here, data flow between the sensor and digital converter and the microprocessor (140) can be controlled.

[0042] The I2C Interface (122) can provide a communication protocol that can communicate the luminance value of the luminance sensor (110) received from the first analog-to-digital converter (111) and the RGB data of the RGB sensor (120) received from the second analog-to-digital converter (121) with the microprocessor (140).

[0043] The PWM (Pulse Width Modulation) frequency generator (131) performs the function of generating a clock signal required for a specific task, and can be used when precise timing is required to perform the task of the microprocessor (140) when turning the Green LED (130) on and off according to the control of the microprocessor (140).

[0044] The PWM frequency generator (131) can control the power of the green LED (130) by adjusting the amplitude of the pulse according to the control of the microprocessor (140).

[0045] The PWM frequency generator (131) generates an output waveform of a PWM square wave (TTL), has a frequency range of 1 Hz to 50 kHz, and can convert a PWM input signal into a standard TTL (Transistor-Transistor Logic) level.

[0046] Green LED (130) has the advantage of being closer to the center of the visible light spectrum, making it easier for the eyes to detect colors at night and in tunnels.

[0047] As shown in Fig. 2, the Green LED (130) can be arranged in a row with a brightness sensor (110) and an RGB sensor (120) on both sides.

[0048] The reason why the Green LED (130) is positioned at the center is to measure and analyze external light and light emission wavelengths uniformly from both sides of the luminance sensor (110) and RGB sensor (120) using the main light wavelength, and to reduce sensor reception errors of the luminance sensor (110) and RGB sensor (120).

[0049] A vehicle lamp is an object made by grinding and curved the surface of a transparent body such as glass or crystal to gather or disperse light. It is not limited to this, and any object that is a transparent lens, such as the windshield of a vehicle, can be applied.

[0050] The microprocessor (140) is a central control unit that collects and processes all data from the brightness sensor (110), RGB sensor (120), and Green LED (130).

[0051] The microprocessor (140) receives information from the brightness sensor (110) and the RGB sensor (120), analyzes it, and performs detection of the vehicle lamp. For example, the brightness, color, and status of the vehicle lamp can be determined.

[0052] The microprocessor (140) can detect the vehicle lamp performance in advance and take various control and actions using the detected information.

[0053] The microprocessor (140) initializes the brightness sensor (110) and the RGB sensor (120), and also initializes the microprocessor itself (S100).

[0054] The reason for initializing the microprocessor (140), the brightness sensor (110), and the RGB sensor (120) is that, for example, frost does not occur on the vehicle lamp until the interior of the space is heated by the headlight, except when the headlight part of the vehicle is frozen or icy, so that external frost and normal conditions can be confirmed and abnormalities can be confirmed through initialization.

[0055] The microprocessor (140) compares the luminance reception value (A) of the luminance sensor (110) with the daytime reference luminance value (D) of the preset luminance sensor measured by the ambient brightness during the day, and the tunnel reference luminance value (T) of the preset luminance sensor measured by the ambient brightness during the tunnel, to determine whether it is a daytime section, an evening section, or a tunnel section.

[0056] The microprocessor (140) can control the frequency generator (131) connected to the green LED (130) to turn on the green LED (130) and generate a wavelength for detecting the sex.

[0057] The microprocessor (140) can detect the frost state of the vehicle lamp by comparing the green brightness reception value (G(n)) of the RGB sensor (120) measured by receiving the light reflected from the vehicle lamp and the wavelength for detecting frost generated from the green LED (130) with the sensor reception level of the reference intensity value of the green wavelength band measured by the RGB sensor (120) set for each section.

[0058] The microprocessor (140) compares the luminance reception value (A) received from the luminance sensor (110) with the preset daytime reference luminance value (D) (S101).

[0059] A may represent the luminance reception value of the luminance sensor (110) measured by external light or ambient brightness. The luminance reception value may be a value representing the luminance intensity measured by the luminance sensor (110).

[0060] D can represent the daytime reference luminance value of a preset luminance sensor (110) measured by external light or ambient brightness during the daytime period.

[0061] The microprocessor (140) determines whether the luminance reception value (A) received from the luminance sensor (110) is greater than the preset daytime reference luminance value (D) of the luminance sensor (110) (S102).

[0062] When the microprocessor (140) determines that the luminance reception value (A) is greater than the daytime reference luminance value (D), it recognizes that it is a daytime section, generates a frequency generation signal for daytime recognition, and transmits it to the PWM frequency generation unit (131).

[0063] The PWM frequency generator (131) turns on the green LED (130) under the control of the microprocessor (140) to generate a wavelength for detecting the sex (S103).

[0064] The reason why Green LED (130) is used is that in the case of most halogen & LED headlights, the basic wavelength of the phosphor is high in the BLUE or RED part, so it is used to increase the discrimination power of the light reception value of the RGB sensor (120).

[0065] The microprocessor (140) compares the green brightness reception value (G(n)) of the RGB sensor (120) with RGB_D(n) (S104).

[0066] Here, the green brightness reception value of the RGB sensor (120) may represent the green brightness reception value measured by the RGB sensor (120) due to the surrounding brightness. In other words, the green brightness reception value of the RGB sensor (120) may be a value representing the intensity value of the green wavelength band measured by the RGB sensor (120) due to the emission wavelength of the green LED (130).

[0067] RGB_D(n) can represent the sensor reception level of the first reference intensity value of the green wavelength band measured by the preset RGB sensor (120) during the day.

[0068] n can represent the degree of ice crystals in stages 0, 1, 2, 3, and 4. As n increases from stage 0 to stage 4, it indicates that there are more ice crystals.

[0069] Frost may be ice crystals that form on the interior surface of a window pane when water vapor in the air sublimates when the temperature outside the window is very low in winter.

[0070] RGB_D(0), RGB_D(1), RGB_D(2), RGB_D(3), RGB_D(4) indicate that the larger n is, the higher the sensor reception level is, and it can be judged that the degree of sexuality is high.

[0071] This means that as you progress from stage 1 to stage 2 to stage 3, the number of ice crystals increases and the thickness of the ice crystals increases.

[0072] The microprocessor (140) determines whether the green brightness reception value (G(n)) of the RGB sensor (120) is greater than 0 and less than RGB_D(0) (S105), and if the green brightness reception value (G(n)) of the RGB sensor (120) is greater than 0 and less than RGB_D(0) (0 <G(n)<RGB_D(0)), 차량 램프가 성에 상태가 아니라고 판단한다(S106).

[0073] The microprocessor (140) determines whether the green brightness reception value (G(n)) of the RGB sensor (120) is greater than 0 and less than RGB_D(0), and if it determines that the green brightness reception value (G(n)) of the RGB sensor (120) is greater than 0 and not less than RGB_D(0), it determines whether the green brightness reception value (G(n)) of the RGB sensor (120) is greater than RGB_D(0) and less than RGB_D(1) (RGB_D(0) <G(n)<RGB_D(1))(S107).

[0074] The microprocessor (140) determines that the vehicle lamp is not in the on state when the green brightness reception value (G(n)) of the RGB sensor (120) is greater than RGB_D(0) and less than RGB_D(1) (S108).

[0075] If the microprocessor (140) determines that the green brightness reception value (G(n)) of the RGB sensor (120) is greater than RGB_D(0) and not less than RGB_D(1), it determines that the green brightness reception value (G(n)) of the RGB sensor (120) is greater than RGB_D(1) and less than RGB_D(2) (RGB_D(1) <G(n)<RGB_D(2))(S109).

[0076] The microprocessor (140) determines that the vehicle lamp is in the first stage of the star state when the green brightness reception value (G(n)) of the RGB sensor (120) is greater than RGB_D(1) and less than RGB_D(2) (S110).

[0078] The microprocessor (140) determines that the vehicle lamp is in a two-stage star state when the green brightness reception value (G(n)) of the RGB sensor (120) is greater than RGB_D(2) and less than RGB_D(3) (S112).

[0079] If the microprocessor (140) determines that the green brightness reception value (G(n)) of the RGB sensor (120) is greater than RGB_D(2) and not less than RGB_D(3), it determines whether the green brightness reception value (G(n)) of the RGB sensor (120) is greater than RGB_D(3) and less than RGB_D(4) (RGB_D(3) <G(n)<RGB_D(4))(S113).

[0080] The microprocessor (140) determines that the vehicle lamp is in a three-stage star state when the green brightness reception value (G(n)) of the RGB sensor (120) is greater than RGB_D(3) and less than RGB_D(4) (S114).

[0081] The microprocessor (140) can further improve the accuracy of detecting the frost state by judging the frost state of the vehicle lamp while increasing the frost state stage.

[0082]

[0084] Here, T may represent the tunnel reference luminance value of the luminance sensor (110) measured by external light or ambient brightness when it is a tunnel section.

[0085] The microprocessor (140) determines whether the preset daytime reference luminance value (D) is greater than the luminance reception value (A) received from the luminance sensor (110) and whether the luminance reception value (A) is greater than the preset tunnel reference luminance value (T) (D>A>T) (S116).

[0086] When the preset daytime reference luminance value (D) is greater than the luminance reception value (A) received from the luminance sensor (110) and the luminance reception value (A) is greater than the preset tunnel reference luminance value (T), the microprocessor (140) recognizes the tunnel section and generates a frequency generation signal for tunnel recognition and transmits it to the PWM frequency generation unit (131).

[0093] If the microprocessor (140) determines that the green brightness reception value (G(n)) of the RGB sensor (120) is greater than RGB_T(0) and not less than RGB_T(1), it determines that the green brightness reception value (G(n)) of the RGB sensor (120) is greater than RGB_T(1) and less than RGB_T(2) (RGB_T(1) <G(n)<RGB_T(2))(S123).
