[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a system, product or device comprising a series of units is not necessarily limited to those units clearly listed, but may include other units that are not clearly listed or inherent to these products or devices.

[0027] According to an embodiment of the present application, an embodiment of a method for processing a vehicle alarm icon is provided. Figure 1 is a flow chart of a method for processing a vehicle alarm icon according to an embodiment of the present application, such as Figure 1 As shown, the method includes:

[0028] Step S102 : in response to receiving a display signal for displaying a vehicle alarm icon, generating a first alarm icon matching the display signal.

[0029] The display signal in the above steps refers to the signal generated when a system or component in the vehicle fails. It is used to characterize the failure in the vehicle and requires the display of a vehicle alarm icon. Different types of vehicle failures correspond to different display signals and require different vehicle alarm icons to be displayed.

[0030] The first alarm icon mentioned above is a graphic symbol generated according to the display signal, which is used to remind the user of faults existing in the vehicle, such as power system failure, low fuel, engine overheating, seat belt not fastened, brake failure, etc.

[0031] In an optional embodiment, the processing component that generates the first alarm icon matching the display signal according to the display signal may be a SOC (System on Chip) or other forms of processors, such as an ASIC (Application-Specific Integrated Circuit), a DSP (Digital Signal Processor), etc. The following description is made by taking the SOC as an example.

[0032] After receiving the alarm information or specific message of power system failure, that is, the display signal, the SOC will determine the vehicle fault type corresponding to the display information based on the pre-defined communication signal on the vehicle CAN bus and the signal value of the display signal. The vehicle fault type may include but is not limited to vehicle brake system fault, vehicle power system fault, vehicle on-chip system fault, etc. Different vehicle fault types correspond to different alarm icons. After determining the vehicle fault type, the internal engine is called to depict the first alarm icon corresponding to the vehicle fault type, and a first alarm icon matching the display signal is generated.

[0033] Step S104, adjusting the background color of the first alarm icon to obtain an adjusted first icon.

[0034] The base color of the first alarm icon in the above steps is the background color of the first alarm icon, that is, the background color of the area where the first alarm icon is located.

[0035] The adjusted first icon in the above step may be a solid color icon or an icon with a fixed background color.

[0036] In an optional embodiment, the SOC may remove the background color of the first alarm icon to extract the pure color portion of the icon as the first icon. The SOC may also remove the transparency of the background color of the first alarm icon to make the background color of the obtained first icon become a fixed color.

[0037] The purpose of adjusting the background color of the first alarm icon is to obtain a stable CRC value when calculating the CRC (Cyclic Redundancy Check) value, that is, the check value, using the adjusted first icon. Whether the check process is performed on the first icon with the background color removed or the first icon with the transparency removed, the CRC value calculated each time can be made uniform, and a stable CRC value can be obtained, thereby improving the accuracy of the test.

[0038] Step S106: verify the first alarm icon based on the adjusted first icon to obtain a first verification result, wherein the first verification result is used to indicate whether the first alarm icon is correct.

[0039] In an optional embodiment, a cyclic redundancy algorithm can be used on the SOC to calculate the CRC value of the adjusted first icon. Then, according to the type of vehicle fault, a standard CRC value corresponding to the vehicle fault type is determined from multiple standard CRC values ​​pre-stored by the MCU (Microcontroller), and the calculated CRC value is transmitted from the SOC to the MCU and compared with the standard CRC value. By comparing whether the calculated CRC value is consistent with the standard CRC value, it is determined whether the first alarm icon is correct, and a first verification result is obtained.

[0040] In another optional embodiment, the first icon on the SOC is transmitted to the MCU, and according to the type of vehicle fault, a standard icon corresponding to the type of vehicle fault is determined from a plurality of standard icons pre-stored in the MCU. The first icon and the standard icon are compared, and if the two are consistent, it is determined that the first alarm icon is correct, and if the two are inconsistent, it is determined that the first alarm icon is incorrect.

[0041] Step S108, in response to the first verification result being that the first alarm icon is correct, displaying the first alarm icon on a display screen of the vehicle.

[0042] The above-mentioned display screen may be a vehicle digital instrument panel, but is not limited thereto, and may also be a liquid crystal display screen, an interactive display screen, etc.

[0043] In an optional embodiment, the MCU returns the first verification result to the SOC. If the first verification result shows that the first warning icon is correct, the first warning icon in the SOC is output to the video stream to be provided to the display screen, and the first warning icon is displayed to the user through the display screen, so as to promptly remind the user that the vehicle is in potential danger.

[0044] In an embodiment of the present application, in response to receiving a display signal for displaying a vehicle alarm icon, a first alarm icon matching the display signal is generated; the background color of the first alarm icon is adjusted to obtain an adjusted first icon; the first alarm icon is verified based on the adjusted first icon to obtain a first verification result; in response to the first verification result being that the first alarm icon is correct, the first alarm icon is displayed on the display screen of the vehicle. It is easy to notice that by first adjusting the background color of the first alarm icon and then verifying based on the adjusted first icon, a relatively stable verification value can be obtained during the verification process, thereby improving the accuracy of the first verification result, ensuring that the first alarm icon displayed on the vehicle display screen is correct, achieving the purpose of improving the accuracy of the alarm icon display, and thus solving the technical problem of low accuracy of the alarm icon display.

[0045] Optionally, the background color of the first alarm icon is adjusted to obtain an adjusted first icon, including: identifying the color of the first alarm icon to determine the background color of the first alarm icon; generating a target mask based on position information of the background color in the first alarm icon; and fusing the target mask with the first alarm icon to obtain the adjusted first icon.

[0046] The background color in the above step is the color of the background part of the first alarm icon except the icon itself.

[0047] The position information in the above steps is used to characterize the position of the background color in the first alarm icon. The position information of the background color in the first alarm icon is determined to determine the area in the first alarm icon that needs to be made transparent so as to generate a target mask and remove the background color of the first alarm icon.

[0048] The target mask in the above steps refers to a binary image generated according to the position information of the background color, used to identify the background color area, and remove the background color of the first alarm icon. It is usually a black and white image, in which the background color area is black and other areas are white. In addition to the form of a black and white image, the target mask can also be in the form of a grayscale image, a shape mask, or a depth image, but is not limited thereto.

[0049] In an optional embodiment, color recognition technology can be used to identify the background color of the first alarm icon, and determine the position of the background color in the first alarm icon to obtain the position information of the background color in the first alarm icon. Use mask technology to generate a black and white image of the same size as the first alarm icon, set the position corresponding to the background color to black, and set other positions to white to obtain a target mask. Superimpose the target mask on the first alarm icon so that the target mask and the first alarm icon are aligned. After applying the target mask to the first alarm icon, the area corresponding to the black part of the target mask in the first alarm icon will be removed, that is, it will become transparent, and the area corresponding to the white part will be retained, so as to obtain the first icon after removing the background color.

[0050] The first alarm icon is subjected to background color removal processing, that is, after the background color removal processing, the pure color part of the first alarm icon is extracted to obtain the first icon, so that the verification value calculated based on the first icon each time tends to be unified, which is convenient for the MCU to proofread the verification value corresponding to the first alarm icon.

[0051] Optionally, adjusting the background color of the first alarm icon to obtain the adjusted first icon includes: removing the transparency of the first alarm icon to obtain the adjusted first icon.

[0052] In an optional embodiment, an interface of image processing software can be introduced, and the transparency of the first alarm icon can be removed by using the function of the image processing software to obtain a first icon of a single color. Compared with the first alarm icon, removing the transparency will change the background color of the first icon to a fixed color. By calculating the check value based on the first icon after removing the transparency, a stable check value can be obtained, which is convenient for the MCU to calibrate the check value corresponding to the first alarm icon.

[0053] Optionally, the first alarm icon is verified based on the adjusted first icon to obtain a first verification result, including: generating a target verification value of the first alarm icon based on the adjusted first icon; determining a target preset verification value of the first alarm icon from multiple preset verification values, wherein different preset verification values ​​correspond to different alarm icons; and comparing the target verification value with the target preset verification value to obtain the first verification result.

[0054] The target check value in the above step is a value obtained by calculating the adjusted first icon using a check algorithm. The check algorithm can be CRC, parity check, or hash function, but is not limited thereto.

[0055] The preset check value in the above steps is a pre-set check value. Different vehicle fault types correspond to different standard icons, and different preset check values ​​are values ​​calculated based on the standard icons after the background color adjustment using the check algorithm, where different standard icons are correct icons corresponding to different vehicle fault types. The specific data of the preset check value can be preset according to the actual application situation, and the specific value of the preset check value is not limited here.

[0056] The target preset check value in the above steps is a preset check value corresponding to the first alarm icon, and can be determined according to the vehicle fault type corresponding to the first alarm icon.

[0057] In an optional embodiment, if the adjusted first icon is an icon with the background color removed, the multiple standard verification values ​​pre-stored in the MCU are values ​​obtained by verifying and calculating multiple standard icons with the background color removed using a verification algorithm. If the adjusted first icon is an icon with transparency removed, the multiple standard verification values ​​pre-stored in the MCU are values ​​obtained by verifying and calculating multiple standard icons with transparency removed using a verification algorithm.

[0058] The SOC uses a verification algorithm to process the adjusted first icon, generates a target verification value for the first alarm icon, and sends the target verification value for the first alarm icon to the MCU. When the display signal is generated, the MCU will also receive the display signal synchronously, and determine the standard icon according to the vehicle fault type corresponding to the display signal, and then determine the standard verification value corresponding to the vehicle fault type from multiple standard verification values ​​according to the standard icon, that is, the target preset verification value.

[0059] The target verification value of the first alarm icon is compared with the target preset verification value. If the two are consistent, it is determined that the first alarm icon is correct; otherwise, it is determined that the first alarm icon is incorrect.

[0060] The image processing capability of MCU is limited, and it is not possible to directly convert multiple standard icons into numerical values ​​and store them. Therefore, the standard icons are processed with background colors, and relatively stable verification values ​​are calculated and stored to verify the first alarm icon generated in real time. At the same time, MCU is a component that meets functional safety requirements and can perform reliable and stable comparison processing on the target verification value and the target preset verification value. Therefore, SOC can be selected to generate the target preset verification value of the first alarm icon, and MCU can be selected to perform verification.

[0061] Optionally, based on the adjusted first icon, a target verification value of the first alarm icon is generated, including: converting the format of the adjusted first icon to obtain a binary data stream corresponding to the adjusted first icon; and calculating the binary data stream using a verification algorithm to obtain a target verification value.

[0062] The binary data stream in the above steps is a data sequence composed of binary bits, which can be used as an input of a verification algorithm to calculate a target verification value of the first alarm icon.

[0063] In an optional embodiment, the adjusted first icon can be saved as a binary file, and then the binary file is read and converted into a binary data stream through a format conversion command. A CRC algorithm can be selected as a verification algorithm, and the binary data stream is input into the CRC algorithm to generate a target verification value.

[0064] Optionally, the target verification value is compared with the target preset verification value to obtain a first verification result, including: calculating the difference between the target verification value and the target preset verification value; if the absolute value of the difference is less than or equal to a preset threshold, determining that the first verification result is that the first alarm icon is correct; if the absolute value of the difference is greater than the preset threshold, determining that the first verification result is that the first alarm icon is incorrect.

[0065] The preset threshold in the above steps is a preset threshold, which can be preset according to actual application conditions, and no restriction is imposed on the specific value of the preset threshold.

[0066] In an optional embodiment, the difference between the target check value and the target preset check value can be calculated, and the absolute value of the difference can be calculated. Exemplarily, the preset threshold can be set to 0.001, that is, if the difference between the target check value and the target preset check value appears after three decimal places, the first alarm icon is the correct icon; the preset threshold can also be set to 0.0001, that is, if the difference between the target check value and the target preset check value appears after five decimal places, the first alarm icon is the correct icon, but the above values ​​are only examples, and the specific values ​​of the preset thresholds that can be selected in actual applications are not limited to this. If the absolute value of the difference is less than or equal to the preset threshold, it is determined that the first check result is that the first alarm icon is correct; if the absolute value of the difference is greater than the preset threshold, it is determined that the first check result is that the first alarm icon is incorrect.

[0067] Optionally, generating a first alarm icon matching the display signal includes: determining a target image feature value corresponding to the display signal from a plurality of image feature values; and rendering the first alarm icon based on the target image feature value.

[0068] The image feature values ​​in the above steps are values ​​used to characterize the content or attributes of the image, including but not limited to color feature values ​​describing the color distribution of each pixel in the image, texture feature values ​​describing the distribution and characteristics of the texture in the image, shape feature values ​​describing the shape and contour characteristics of the object in the image, size feature values ​​describing the size and proportional relationship of the image, etc. The icon described by the image feature value can be rendered according to the image feature value.

[0069] The target image feature value in the above steps is the image feature value of the first alarm icon corresponding to the display signal.

[0070] In an optional embodiment, the vehicle accident type is determined according to the display signal, and then the target image feature value of the alarm icon corresponding to the vehicle accident type is determined from a plurality of pre-stored image feature values. Then, the service responsible for drawing the alarm icon on the SOC draws the icon according to the target image feature value to obtain the first alarm icon.

[0071] Optionally, in response to the first verification result being that the first alarm icon is correct, displaying the first alarm icon on a display screen of the vehicle includes: determining a screen buffer corresponding to the first alarm icon; and outputting data in the screen buffer to the display screen.

[0072] The screen buffer in the above steps is a memory area used to store graphics display content.

[0073] In an optional embodiment, when the first verification result is that the first alarm icon is correct, the first alarm icon needs to be displayed on the display screen. When drawing the first alarm icon, the first alarm icon has been drawn into the screen buffer, so when displaying the first alarm icon, it is necessary to determine the screen buffer corresponding to the first alarm icon, and then copy the data of the screen buffer to the display screen at a certain refresh frequency, so as to realize the display of the first alarm icon on the display screen. For example, the refresh frequency can be 60 times per second, but it is not limited thereto, and the refresh frequency can also be set to other values ​​according to actual application conditions.

[0074] Optionally, in response to the first verification result being that the first alarm icon is incorrect, the method also includes: regenerating a second alarm icon that matches the alarm icon display signal; adjusting the background color of the second alarm icon to obtain an adjusted second icon; verifying the second alarm icon based on the adjusted second icon to obtain a second verification result, wherein the second verification result is used to characterize whether the second alarm icon is correct; in response to the second verification result being that the second alarm icon is correct, displaying the second alarm icon on the vehicle's display screen.

[0075] The second alarm icon in the above steps is an alarm icon that is regenerated based on the display signal corresponding to the first alarm icon when the first verification result shows that the first alarm icon is incorrect.

[0076] The above steps are to obtain the icon after adjusting the background color of the second alarm icon.

[0077] The second verification result in the above step is used to indicate whether the second alarm icon is correct, and is obtained by verifying the second alarm icon.

[0078] In an optional embodiment, when the verification result shows that the first alarm icon is incorrect, the display screen does not display the first alarm icon, but the SOC regenerates the alarm icon, that is, the second alarm icon, and the MCU verifies the accuracy of the second alarm icon again according to the vehicle alarm icon processing method. If the second verification result shows that the second alarm icon is correct, the second alarm icon is displayed on the vehicle display screen.

[0079] Optionally, the method further includes: testing the power system of the vehicle to obtain a test result; if the test result is that the power system of the vehicle has failed, generating a display signal for displaying a vehicle alarm icon.

[0080] The power system of the vehicle in the above steps is a system that directly or indirectly provides driving force for the vehicle, and can be a transmitter, a transmission, or a transmission system, but is not limited thereto.

[0081] In an optional embodiment, when the power system of the vehicle fails, the detection component detects an abnormality, determines the current abnormality type as a power system failure according to an abnormality handling code for handling the abnormal situation, generates a display signal corresponding to the power system failure, and transmits the display signal to the SOC.

[0082] A preferred embodiment is described below. Figure 2 is a schematic diagram of an optional vehicle alarm icon processing system according to an embodiment of the present application, such as Figure 2As shown, an optional vehicle alarm icon processing system includes: a system on chip, a microprocessor and a display screen, wherein the system on chip includes a rendering engine, a background color processing unit, a check value generating unit, and the microprocessor includes a memory. When a failure of the vehicle's power system is detected, an alarm icon display signal is generated. After the system on chip, i.e., SOC, receives the display signal, the rendering engine in the SOC draws the icon according to the alarm icon display signal, generates a first alarm icon, and then sends the first alarm icon to the background color processing unit. The background color processing unit removes the background color of the first alarm icon to obtain a single-color icon, and sends the single-color icon to the check value generating unit. The check value generating unit performs CRC calculation processing on the single-color icon to obtain a check value, and then sends the check value to the microprocessor. The microprocessor is also the MCU mentioned above. The microprocessor queries the target preset check value of the alarm icon stored in advance from the memory, compares the check value with the target preset check value, obtains the check result, and returns the check result to the system on chip. If the verification result is that the first alarm icon is correct, the display obtains the first alarm icon from the system on chip and displays it; if the verification result is that the first alarm icon is incorrect, the system on chip regenerates the alarm icon, that is, the second alarm icon, and re-verifies it by the microprocessor.

[0083] The above-mentioned vehicle alarm icon processing system can use the MCU to compare the CRC value of the first alarm icon, rather than using a separate OSD (On-Screen Display) chip for image verification. Since the OSD chip has certain requirements for the display resolution and display size of the display screen, and also has certain requirements for the style, background and color of the alarm icon, it has high limitations. Therefore, the use of the vehicle alarm icon processing system in the embodiment of the present application can achieve the purpose of improving the display accuracy of the alarm icon while avoiding the limitations caused by the OSD chip.
