[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Figure 1 FIG. 1 is a flow chart of a method for detecting a vehicle atmosphere light according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0025] S1, receiving a test instruction from a user, and obtaining a test mode of the atmosphere light according to the test instruction.

[0026] The test modes include: automatic calibration color coordinate test mode and color gradient time test mode.

[0027] S2, if the test mode is the automatic calibration color coordinate test mode, then obtain the color selected by the user to be tested and calibrated, and light up the ambient light in sequence according to the color selected by the user to be tested and calibrated, and the lighting time of each color is the first preset time. During the lighting process of the ambient light, read the color coordinates and luminous flux corresponding to the different colors of the ambient light, and read the software version number and hardware version number of the ambient light through the LIN bus, and calculate the color deviation of the current color according to the color coordinates corresponding to different colors and the color coordinates required by the customer, and save the reading results and the color deviation calculation results in the form of a first electronic document.

[0028] Specifically, the color coordinates required by the customer, that is, the color coordinates that the ambient light needs to achieve, can be set in advance according to the requirements through relevant devices, and can be directly called during the detection process. If the color coordinates of a certain color measured are (x, y), (u, v), that is, the color coordinates of a certain color of the ambient light read during the lighting process of the ambient light are (x, y), (u, v), where If the customer of a certain color requires the color coordinates to be (x', y'), (u', v'), then the calculation formula for the color deviation Δ of the current color is: It can be understood that the color coordinates (x, y) actually measured are detected by using a light color detector, the corresponding customer required color coordinates (x', y') stored are retrieved, and the color deviation corresponding to the current color is calculated using the above formula.

[0029] S3, if the test mode is the color gradient time test mode, then the gradient mode and gradient color selected by the user are obtained, and the ambient light is controlled to light up in the gradient mode and gradient color. During the lighting process of the ambient light, the color coordinates and luminous flux of the ambient light are read in real time according to the time axis at a first preset frequency, and the software version number and hardware version number of the ambient light are read through the LIN bus, and the gradient time of the gradient color is calculated according to the time axis and the color coordinates corresponding to the time axis, and the reading results and the gradient time calculation results are saved in the form of a second electronic document, wherein the gradient mode includes: uniform attenuation change and uniform incremental change.

[0030] In the embodiment of the present invention, the first preset time may be 10 ms, and the first preset frequency may be 100 Hz. The first electronic document and the second electronic document may be Ecxcel documents.

[0031] It can be understood that the main purpose of the automatic calibration color coordinate test mode in the present invention is to detect whether the color difference and luminous flux of different colors of the ambient light meet the requirements, and the main purpose of the color gradient time test mode is to detect whether the gradient time and luminous flux of different gradient colors of the ambient light meet the requirements.

[0032] Specifically, the user needs to select the test mode and the color of the atmosphere light to be tested and calibrated in the detection system in advance during the detection. For example, the color to be tested and calibrated can be checked in the 253-color drop-down box in the corresponding software in the detection system. The automatic calibration color coordinate test mode can calibrate the colors to be measured in turn. The color gradient time test mode can select the gradient color combination to be measured in turn. The gradient color combination includes two colors, that is, gradually changing from one color to another. After the selection is completed, touch the corresponding start switch or click the corresponding start button to start the test, and select the corresponding test mode to issue a test instruction.

[0033] After the test starts, the detection system can obtain the test mode of the atmosphere light according to the test instruction. If the test mode is the automatic calibration color coordinate test mode, the color selected by the user to be tested and calibrated is obtained, and the atmosphere light is lit in sequence according to the color selected by the user to be tested and calibrated. The lighting time of each color can be 10ms. During the lighting process, the atmosphere light color coordinates, luminous flux, software version number, hardware version number and other related information will be read immediately, and the reading results will be automatically recorded in real time to the designated first electronic document. At the same time, it is necessary to calculate the color deviation of the current color according to the color coordinates corresponding to different colors and the color coordinates required by the customer, and retain the calculation results. It is also necessary to judge whether the color selected by the user to be tested and calibrated meets the requirements based on the calculation results and color deviation requirements, and record the judgment results (satisfied / not satisfied). For example, if the color deviation of the current color is less than 0.01, it is judged that the current color meets the requirements. The acquisition results, color deviation calculation results and judgment results can be saved in the form of an Ecxcel table, for example Figure 2 Thus, it is possible to clearly know whether the current ambient light meets the lighting requirements according to the saved Ecxcel table.

[0034] If the test mode is the color gradient time test mode, the gradient mode and gradient color (usually 2, i.e., gradient from one color to another) selected by the user are obtained, and the test system will light up the atmosphere light according to the selected gradient mode and gradient color. From the beginning of lighting, the test system will read the color coordinates, luminous flux, software version number, hardware version number and other related information of the atmosphere light in real time according to the time axis at a frequency of 100Hz (10ms / time), and automatically record the reading results in real time to the designated second electronic document. At the same time, it is necessary to calculate the gradient time of the two gradient colors according to the time axis, and calculate the color deviation of the two gradient colors, and then determine whether the gradient time meets the preset requirements, and determine whether the gradient color meets the requirements. For example, if the difference between the gradient time and the preset gradient time is within the preset range, it is determined that the gradient time meets the requirements, if the color deviation of the two gradient colors is less than 0.01, it is determined that the gradient color meets the requirements, and if both the gradient color and the gradient time meet the requirements, it is determined that the current atmosphere light meets the gradient requirements. The acquisition results, color deviation calculation results, gradient time and judgment results can be saved in the form of Ecxcel tables, for example Figure 3 In the form shown, color 1 and color 2 in the figure represent that the gradient color changes from color 1 to color 2. Therefore, it can be clearly known whether the current atmosphere light meets the gradient requirement according to the saved Ecxcel table.

[0035] Therefore, the method can automatically switch the color of the automobile ambient light and detect different colors of the ambient light and record the detection data, thereby realizing automated, efficient, high-precision and real-time detection of the ambient light.

[0036] According to one embodiment of the present invention, the above-mentioned vehicle atmosphere light detection method may further include: during the lighting process of the atmosphere light, reading the vehicle model information, RGB node voltage AD feedback value, fault information, and chip temperature information corresponding to the atmosphere light through the LIN bus, and saving the reading results in the form of a first electronic document and / or a second electronic document.

[0037] That is to say, no matter it is the automatic calibration color coordinate test mode or the color gradient time test mode, during the lighting process of the ambient light, the vehicle model information, RGB node voltage AD feedback value (including "R", "G", "B" node voltage AD feedback value), fault information, and chip temperature information corresponding to the current ambient light can be read through the LIN bus, and the read results can be stored in the specified file to make the detection information more comprehensive and rich.

[0038] According to one embodiment of the present invention, a 0x3C diagnostic query message can be sent to the ambient light LIN bus through the LIN bus sending and receiving device to read the ambient light's software version number, hardware version number, corresponding vehicle model information, RGB section voltage AD feedback value, fault information, and chip temperature information.

[0039] Specifically, the 0x3C diagnostic query message is sent through the LIN bus sending and receiving device. The query content is distinguished by Byte3 of the message: REQ.ID. When REQ.ID = 0x20, the software and hardware version number and vehicle model information of the ambient light are queried. When the ambient light sends 0x3D through the controller, the message data is supplemented to reply the diagnostic information. When REQ.ID = 0x25, the ambient light status is queried, including: fault information, chip temperature information, color coordinates, and luminous flux information. When the ambient light sends 0x3D through the controller, the message data is supplemented to reply the diagnostic information.

[0040] The query content is distinguished by Byte4: REQ.ID of the message. When REQ.ID=0x10, query the node voltage of "R" in the RGB LED of the atmosphere light. When the controller sends 0x3D, the atmosphere light supplements the message data to reply the diagnostic information; when REQ.ID=0x11, query the node voltage of "G" in the RGB LED of the atmosphere light. When the controller sends 0x3D, the atmosphere light supplements the message data to reply the diagnostic information; when REQ.ID=0x12, query the node voltage of "B" in the RGB LED of the atmosphere light. When the controller sends 0x3D, the atmosphere light supplements the message data to reply the diagnostic information.

[0041] According to an embodiment of the present invention, the above-mentioned vehicle ambient light detection method may further include: if the test mode is an automatic calibration color coordinate test mode, obtaining the brightness to be tested and calibrated selected by the user, and lighting the ambient light in sequence according to the brightness to be tested and calibrated and the corresponding color to be tested and calibrated, and in the process of lighting the ambient light, reading the brightness corresponding to different colors of the ambient light, and saving the reading result in the form of a first electronic document;

[0042] If the test mode is a color gradient time test mode, the gradient brightness selected by the user is obtained, and the ambient light is controlled to light up in a gradient mode, gradient color, and gradient brightness. During the lighting process of the ambient light, the brightness of the ambient light is read in real time according to the time axis at a first preset frequency, and the reading result is saved in the form of a second electronic document, wherein the gradient brightness includes 8 levels of brightness, and the 8 levels of brightness percentages are: 100%, 85%, 60%, 35%, 30%, 22%, 15%, and 0%, respectively.

[0043] Specifically, when detecting the atmosphere light, in addition to detecting the above-mentioned color, gradient time, etc., the brightness can also be detected. Specifically, when detecting, the user needs to perform the test mode, the color of the atmosphere light to be tested and calibrated, the gradient mode and the gradient color in the detection system in advance, and also needs to select the brightness to be tested and calibrated in advance. The automatic calibration color coordinate test mode selects the brightness to be tested and calibrated corresponding to the color to be tested and calibrated in turn. The color gradient time test mode selects the gradient mode and the gradient brightness corresponding to the gradient color in turn. The gradient brightness includes two brightnesses, gradually changing from one brightness to another. The two colors in the gradient color correspond to the two brightnesses in the gradient brightness respectively.

[0044] After the selection is completed, touch the corresponding start switch or click the corresponding start button to start the test, and select the corresponding test mode to issue a test instruction. If the test mode is the automatic calibration color coordinate test mode, the color selected by the user to be tested and calibrated and the brightness corresponding to each color to be tested and calibrated are obtained, and the atmosphere light is lit in sequence according to the brightness to be tested and calibrated and the corresponding color to be tested and calibrated. The lighting time of each color and brightness combination can be 10ms. During the lighting process, in addition to reading the above-mentioned atmosphere light color coordinates, luminous flux, software version number, hardware version number, color deviation of each color and other related information, the brightness corresponding to the different colors of the atmosphere light is read, and the reading results are automatically recorded in real time to the designated first electronic document.

[0045] If the test mode is a color gradient time test mode, the gradient mode, gradient color and corresponding gradient brightness selected by the user are obtained, and the atmosphere light is controlled to light up with the gradient mode, gradient color and gradient brightness. From the beginning of lighting, the test system will read the color coordinates, luminous flux, software version number, hardware version number and other related information of the atmosphere light in real time according to the time axis at a frequency of 100Hz (10ms / time), and it is also necessary to read the brightness of the atmosphere light in real time according to the time axis at a frequency of 100Hz, and save the reading result in the form of a second electronic document. In the present invention, the gradient brightness includes 8 levels of brightness, and the 8 levels of brightness percentage are: 100%, 85%, 60%, 35%, 30%, 22%, 15%, 0%, respectively. When the brightness percentage is 0%, the atmosphere light is off, and the brightness switching frequency is 10ms / time, that is, when controlling the atmosphere light to light up with a gradient brightness, it is necessary to gradually change in the above eight levels.

[0046] In summary, according to the detection method of the automotive atmosphere light of the embodiment of the present invention, the user's test instruction is received, and the test mode of the atmosphere light is obtained according to the test instruction. If the test mode is the automatic calibration color coordinate test mode, the atmosphere light is lit in sequence according to the color to be tested and calibrated selected by the user, the color coordinates and luminous flux corresponding to different colors are read, and the software version number and hardware version number of the atmosphere light are read, and the color deviation of different colors is calculated, and saved in the form of an electronic document; if the test mode is the color gradient time test mode, the atmosphere light is controlled to light up in a gradient mode and gradient color, the color coordinates and luminous flux are read in real time according to the time axis, and the software version number and hardware version number of the atmosphere light are read, and the gradient time of the gradient color is calculated, and saved in the form of an electronic document. This method can automatically switch the color of the automotive atmosphere light and detect different colors of the atmosphere light and record the detection data, thereby realizing the automation, high efficiency, high precision and real-time detection of the atmosphere light.
