[0033] Figure 1 is a flow chart of a vehicle icon display method according to one embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0034] Step S101, obtaining a vehicle icon display signal.

[0035] Step S102 , drawing and rendering the vehicle display icon, generating the vehicle icon and displaying the vehicle icon on the vehicle display screen.

[0036] Step S103, reading a vehicle icon from a display area of ​​the vehicle display screen, and determining a cyclic redundancy check value of a characteristic area of ​​the vehicle icon.

[0037] Step S104, comparing the cyclic redundancy check value with a preset check value to obtain a comparison result.

[0038] Step S105 , in response to the comparison result indicating that the cyclic redundancy check value does not match the preset check value, an icon is output to display an error prompt signal.

[0039] In an embodiment of the present invention, a vehicle icon display signal is obtained; the vehicle display icon is drawn and rendered to generate a vehicle icon and display the vehicle icon on the vehicle display screen; the vehicle icon is read from the display area of ​​the vehicle display screen to determine the cyclic redundancy check value of the characteristic area of ​​the vehicle icon; the cyclic redundancy check value is compared with a preset check value to obtain a comparison result; in response to the comparison result indicating that the cyclic redundancy check value does not match the preset check value, an icon display error prompt signal is output. The present invention uses a method of checking the characteristic area to check the displayed icon, does not need to use the check function of the OSD chip, has no restrictions on the style, display background, position, etc. of the vehicle icon, can improve the display effect of the instrument, and can solve the technical problem in the related art that when the check function of the OSD chip is used to check the icon, there are large restrictions on the style of the alarm icon, which affects the display effect of the instrument.

[0040] Optionally, the shape of the feature area is one of the following: circle, rectangle, triangle.

[0041] Optionally, the size of the feature area is determined according to the size of the vehicle icon.

[0042] Optionally, the position of the feature area is determined according to the style of the vehicle icon.

[0043] Optionally, a vehicle icon is read from a display area of ​​a vehicle display screen to determine a cyclic redundancy check value of a characteristic area of ​​the vehicle icon, including: reading a vehicle icon from a display area of ​​a vehicle display screen to determine a style of the vehicle icon; determining a characteristic area of ​​the vehicle icon based on the style of the vehicle icon; and determining a cyclic redundancy check value of the characteristic area.

[0044] Optionally, the vehicle icon display method further includes: in response to a comparison result indicating that the cyclic redundancy check value does not match a preset check value, determining a replacement icon for the vehicle icon, and displaying the replacement icon on the vehicle display screen, wherein the replacement icon is used to characterize a vehicle icon display error.

[0045] Based on the above embodiment, specifically, after receiving the display signal of the alarm icon, the SOC internally draws, renders and integrates the alarm icon, and displays the display content on the display screen through I2C communication. Another SOC communicates with the display screen, takes a screenshot of the display area of ​​the alarm icon, and selects the characteristic area of ​​the icon to calculate the CRC value, and compares it with the pre-stored CRC value. If the comparison result passes, it is considered that the icon is displayed correctly. If the CRC value comparison fails, the information is fed back to the SOC that draws the icon, and other methods are used to remind the alarm information.

[0046] For example, if the vehicle receives an alarm message or a specific message about a power system failure, the SOC in the system will receive the message and call the internal engine to draw the alarm icon and output it to the video stream to be provided to the display. After the icon is drawn, another SOC that meets functional safety will take a screenshot of the characteristic area displayed in the chart on the display and calculate the CRC value; the selection of the characteristic area refers to Figure 2 This SOC stores the correct CRC value of the characteristic area of ​​the alarm icon corresponding to the power system failure. When the SOC calculates the CRC value of the characteristic area actually displayed on the display, it will compare it with the pre-stored CRC value to determine whether the icon is correct. If the icon is wrong, this judgment will be sent to the SOC that draws the icon. The SOC will redraw the icon or use pop-up windows to issue an alarm reminder.

[0047] Exemplarily, a high-performance system on chip (SOC) is used to draw and render the alarm icon to generate a video stream; the video stream is sent to the display screen through I2C communication; another functional safety SOC reads the display content from a specific area of ​​the display screen and calculates the CRC check value of the specific area; the CRC check value is compared with the pre-stored correct CRC value to determine the correctness of the icon display; if the CRC check value comparison fails, the functional safety SOC will feedback the error information to the high-performance SOC to take measures to ensure the effective communication of the alarm information. This method can ensure that the alarm icon can be displayed accurately even in extreme environments, such as high temperature, electromagnetic interference, etc., avoiding driver misjudgment due to display errors and improving driving safety. Application scenarios include but are not limited to digital instrument systems for various types of vehicles such as cars, trucks, and buses.

[0048] In one embodiment of the present invention, the shape of the specific area is a rectangle, and further includes: defining the coordinates and size of the rectangular area to ensure the accuracy of the verification range. By accurately defining the verification area, it is possible to avoid misverification of non-alarm icon areas, thereby improving verification efficiency and accuracy. In practical applications, for example, when a vehicle detects an engine failure, it is possible to quickly and accurately locate the engine failure warning icon area on the display screen for verification to ensure that the icon is displayed correctly.

[0049] In one embodiment of the present invention, the alarm icon display signal is generated by a high-performance SOC system, further comprising: setting trigger conditions for icon display, such as abnormal values ​​of vehicle state parameters, to automatically activate icon display. Through the automatic activation mechanism, it is possible to respond to vehicle state changes in real time, display alarm information in a timely manner, and improve the driver's alertness. For example, when the vehicle's brake system pressure is insufficient, the alarm icon will automatically display to remind the driver to immediately check the brake system to prevent potential driving hazards.

[0050] In one embodiment of the present invention, the alarm icon display is flexible, further comprising: adjusting the icon style, position or background dynamic effect according to the vehicle status change to enhance the visual prompt effect. This dynamic adjustment can not only attract the driver's attention, but also provide more intuitive information prompts according to different vehicle status, thereby improving the driver's reaction speed and driving safety. For example, when the vehicle is low on fuel, the icon can flash and gradually turn red, and the background changes to a warning color, strongly prompting the driver to refuel.

[0051] In one embodiment of the present invention, the implementation chip of the verification method uses the SOC chip of the vehicle, and further includes: configuring the SOC chip to identify a specific video stream area, performing a CRC check and feeding back the result. Through the verification function of the SOC chip, the need for additional hardware can be reduced, the system cost can be reduced, and the real-time and accuracy of the verification can be improved. In practical applications, if a vehicle encounters an emergency during driving, the SOC chip can quickly identify and verify the alarm icon area to ensure the immediate and accurate transmission of information.

[0052] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, a computer, a server, or a grid device, etc.) to execute the methods of various embodiments of the present invention.
