Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a control method for a vehicle instrument system, a control system for a vehicle instrument system, an electronic device, and a computer-readable storage medium. Background Technology

[0002] Accurate readings from a vehicle's instrument panel are crucial for safe driving. However, in recent years, problems such as blackouts and erroneous displays on car instrument panels have become increasingly common. These issues not only cause driver panic but can also lead to safety accidents and negatively impact the brand image of car manufacturers.

[0003] Currently, the mainstream solution for problems such as incorrect speed display or incorrect indicator status in vehicle instrument clusters is to add a verification unit to the instrument cluster's main unit or display screen. This verification unit checks the information displayed by the vehicle's instrument cluster to determine its accuracy. If an error is detected, the verification unit sends the correct display signal to ensure the vehicle's instrument cluster displays the correct information.

[0004] However, relying solely on the verification unit to determine whether the vehicle's instrument system is displaying the correct information has certain limitations.

[0026] The embodiments of the present invention have the following advantages:

[0027] The control scheme for a vehicle instrument system provided in this invention includes a video output unit, a signal conversion unit, and a display unit. This control scheme acquires the original instrument information of the vehicle instrument system, obtains video image output information through the video output unit, obtains video image transmission information through the signal conversion unit, and obtains instrument display information through the display unit. Then, it verifies the original instrument information against the video image output information to obtain a first comparison result, verifies the original instrument information against the video image transmission information to obtain a second comparison result, and verifies the instrument display information against the video image output information to obtain a third comparison result.

[0028] In the background technology, the verification unit only checks the displayed information to determine its correctness, but this can lead to malfunctions or inaccuracies. The vehicle instrument system control scheme provided in this invention introduces a video output unit, a signal conversion unit, and a display unit, comparing information from different sources to determine the accuracy of the displayed information. This multi-source information comparison method is more reliable and can more accurately determine whether the displayed information is correct. For example, if the verification unit malfunctions and cannot correctly determine the displayed information, but the information from the video output unit and the signal conversion unit is still normal, the correctness of the displayed information can be determined through the information from these two units, improving the accuracy and reliability of the displayed information. The comparison result processing logic in this invention enables the vehicle instrument system to have a certain self-diagnostic capability. When the comparison result indicates that the displayed information is abnormal, the vehicle instrument system can perform a reset process according to the abnormality, that is, reset the signal links of the video output unit, the signal conversion unit, and the display unit to correct the display error. This self-diagnostic capability can promptly detect and handle display errors, enhancing the self-repair capability of the vehicle instrument system and improving its stability and reliability. Accurate and reliable displayed information can prevent drivers from panicking or becoming confused due to display errors. For example, displaying an incorrect speed while driving at high speed might lead the driver to make wrong driving decisions, while accurate information can help the driver make correct judgments and decisions, improving driving safety. Furthermore, accurate information can also improve driver comfort, making the driver feel more at ease and reducing driver stress, thus enhancing driving safety.

[0029] In summary, the control scheme for the vehicle instrument system provided by the embodiments of the present invention has beneficial effects on improving the accuracy and reliability of displayed information, enhancing the system's self-diagnostic capabilities, and improving the driver's sense of security and comfort compared to the prior art, thus helping to improve the performance of the vehicle instrument system and the user experience.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] This invention proposes a control scheme for a vehicle instrument system. By introducing a video output unit, a signal conversion unit, and a display unit, combined with comparison logic, it achieves multi-source verification of displayed information. First, the original instrument information of the vehicle instrument system is acquired. Video image output information is obtained through the video output unit, video image transmission information is obtained through the signal conversion unit, and instrument display information is obtained through the display unit. Then, the video image output information is verified against the original instrument information to obtain a first comparison result; the original instrument information is verified against the video image transmission information to obtain a second comparison result; and the instrument display information is verified against the video image output information to obtain a third comparison result. Based on the comparison results, abnormalities in the signal link are identified and reset to ensure the vehicle instrument system displays correct information, thus improving the accuracy, reliability, and user experience of the vehicle instrument system.

[0040] Reference Figure 1 This diagram illustrates a flowchart of the steps involved in controlling a vehicle instrument system according to an embodiment of the present invention. The vehicle instrument system is a core component of a car dashboard, responsible for displaying vehicle operating status information, such as vehicle speed, engine speed, and fuel level. The vehicle instrument system may include a video output unit, a signal conversion unit, and a display unit. To ensure the accuracy and reliability of the instrument system, effective control is required. The control method for this vehicle instrument system may specifically include the following steps:

[0041] Step 101: Obtain the original instrument information of the vehicle instrument system, obtain video image output information through the video output unit, obtain video image pass-through information through the signal conversion unit, and obtain instrument display information through the screen display unit.

[0042] In embodiments of the present invention, this step is fundamental to the control method and requires the acquisition of four types of information:

[0043] Raw instrument data refers to data directly collected by sensors or instruments, such as vehicle speed, engine speed, fuel level, coolant temperature, and tire pressure. This information reflects the vehicle's actual operating status and forms the basis for the information displayed by the instrument system.

[0044] Video image output information: Video output unit generates video image data based on the raw instrument information. The video output unit typically converts the raw instrument information into image format for the driver to view.

[0045] Video image pass-through information: The signal conversion unit transmits the video image output information from the vehicle instrument system's main unit to the video image data on the vehicle instrument system's screen via the vehicle communication system. In some cases, the vehicle instrument system's main unit and screen may not be in the same location, requiring video image pass-through information to achieve image display.

[0046] Instrument panel display information: This refers to the information actually displayed on the instrument panel, including pointers, numbers, and graphics. Instrument panel display information is the primary way for drivers to obtain information about the vehicle's operating status.

[0047] Raw instrument data can be obtained directly from sensors or instruments. Video image output information can be generated by the video output unit of the vehicle's instrument system. Video image pass-through information can be transmitted through the signal conversion unit. Instrument display information can be obtained through the display unit of the instrument system.

[0048] Step 102: Verify the original instrument information with the video image output information to obtain a first comparison result; verify the original instrument information with the video image transmission information to obtain a second comparison result; and verify the instrument display information with the video image output information to obtain a third comparison result.

[0049] In an embodiment of the present invention, this step verifies the acquired information to determine whether the instrument system is functioning properly. The verification includes:

[0050] Verification of instrument panel data and video output: Determine whether the video output accurately reflects the instrument panel data. For example, if the vehicle speed sensor collects a speed of 60 km / h, but the video output shows a speed of 80 km / h, then there is an error in the video output.

[0051] Verification of original instrument data and video image transmission information: Determine whether the video image transmission information has been lost or damaged during transmission. For example, if the vehicle speed sensor collects a vehicle speed of 60 km / h, but the video image transmission information displays a vehicle speed of 0 km / h, it indicates that the video image transmission information has been lost or damaged.

[0052] Verification of instrument panel display information and video image output information: Determine whether the instrument panel display information is consistent with the video image output information. For example, if the instrument panel displays a vehicle speed of 60 km / h, while the video image output information displays a vehicle speed of 80 km / h, it indicates that there is an error in the instrument panel display information.

[0053] The comparison results can be categorized into the following cases:

[0054] Consistent: This indicates that there are no discrepancies between the information and the instrument system is working normally.

[0055] Inconsistency: This indicates discrepancies between information, suggesting a potential malfunction in the instrumentation system.

[0056] Step 103: Determine the abnormality of the signal link where the video output unit, signal conversion unit, and screen display unit are located based on the first comparison result, the second comparison result, and the third comparison result, and perform reset processing according to the abnormality in order to control the vehicle instrument system.

[0057] In an embodiment of the present invention, this step determines whether an anomaly exists based on the comparison result. If an anomaly exists, the instrument system is then controlled according to the anomaly. The control strategy may include:

[0058] Instrumentation is normal: If the comparison results indicate that the instrumentation system is working normally, no control is required.

[0059] Instrument malfunction: If the comparison results indicate a fault in the instrument system, appropriate control measures need to be taken, such as:

[0060] Warning: Issues a warning message to the driver, indicating a possible malfunction in the instrument system.

[0061] Downgrade: Reduce the functionality of the instrument system, such as switching the color instrument panel to black and white mode.

[0062] Failure protection: Measures are taken to prevent instrument system failures from causing more serious consequences, such as limiting vehicle speed.

[0063] The control scheme for a vehicle instrument system provided in this invention includes a video output unit, a signal conversion unit, and a display unit. This control scheme acquires the original instrument information of the vehicle instrument system, obtains video image output information through the video output unit, obtains video image transmission information through the signal conversion unit, and obtains instrument display information through the display unit. Then, it verifies the original instrument information against the video image output information to obtain a first comparison result, verifies the original instrument information against the video image transmission information to obtain a second comparison result, and verifies the instrument display information against the video image output information to obtain a third comparison result. Next, based on the first, second, and third comparison results, it determines any abnormalities in the signal links where the video output unit, signal conversion unit, and display unit are located, and performs reset processing according to the abnormalities to control the vehicle instrument system.

[0064] In the background technology, the verification unit only checks the displayed information to determine its correctness, but this can lead to malfunctions or inaccuracies. The vehicle instrument system control scheme provided in this invention introduces a video output unit, a signal conversion unit, and a display unit, comparing information from different sources to determine the accuracy of the displayed information. This multi-source information comparison method is more reliable and can more accurately determine whether the displayed information is correct. For example, if the verification unit malfunctions and cannot correctly determine the displayed information, but the information from the video output unit and the signal conversion unit is still normal, the correctness of the displayed information can be determined through the information from these two units, improving the accuracy and reliability of the displayed information. The comparison result processing logic in this invention enables the vehicle instrument system to have a certain self-diagnostic capability. When the comparison result indicates that the displayed information is abnormal, the vehicle instrument system can perform a reset process according to the abnormality, that is, reset the signal links of the video output unit, the signal conversion unit, and the display unit to correct the display error. This self-diagnostic capability can promptly detect and handle display errors, enhancing the self-repair capability of the vehicle instrument system and improving its stability and reliability. Accurate and reliable displayed information can prevent drivers from panicking or becoming confused due to display errors. For example, displaying an incorrect speed while driving at high speed might lead the driver to make wrong driving decisions, while accurate information can help the driver make correct judgments and decisions, improving driving safety. Furthermore, accurate information can also improve driver comfort, making the driver feel more at ease and reducing driver stress, thus enhancing driving safety.

[0065] In summary, the control scheme for the vehicle instrument system provided by the embodiments of the present invention has beneficial effects on improving the accuracy and reliability of displayed information, enhancing the system's self-diagnostic capabilities, and improving the driver's sense of security and comfort compared to the prior art, thus helping to improve the performance of the vehicle instrument system and the user experience.

[0066] In one exemplary embodiment of the present invention, an implementation method for controlling the vehicle instrument system is to determine the abnormality of the signal link where the video output unit, signal conversion unit, and display unit are located based on the first comparison result, the second comparison result, and the third comparison result, and to perform reset processing according to the abnormality, wherein when the first comparison result indicates that the original instrument information is different from the video image output information, the second comparison result indicates that the original instrument information is different from the video image transmission information, and the third comparison result indicates that the instrument display information is the same as or different from the video image output information, it is determined that the signal link where the video output unit is located has a fault, or the signal links where both the video output unit and the signal conversion unit are located have a fault, and then the video output unit, or the video output unit and the signal conversion unit, are reset.

[0067] In practical applications, analysis is performed based on the results of the first, second, and third comparisons. If the first comparison result indicates that the original instrument information is different from the video image output information, the second comparison result indicates that the original instrument information is different from the video image transmission information, and the third comparison result indicates that the instrument display information is the same as or different from the video image output information, it suggests a possible anomaly in the signal link where the video output unit or signal conversion unit is located. Based on the analysis results, the probability of a fault in the signal link where the video output unit is located is determined, or it is possible that both the signal links where the video output unit and the signal conversion unit are located are faulty. For different anomaly situations, corresponding reset procedures are performed. If it is determined that the signal link where the video output unit is located is faulty, the video output unit is reset; if it is determined that both the signal links where the video output unit and the signal conversion unit are located are faulty, both units are reset.

[0068] For example, suppose the video output unit in a vehicle's instrument cluster malfunctions, causing incorrect display information. After comparative analysis, it is determined that the fault lies in the signal link where the video output unit is located. In this case, according to the implementation method, the video output unit will be reset to restore normal display function.

[0069] This invention allows for the rapid and accurate identification of signal link anomalies based on comparison results, and the implementation of corresponding measures. Timely reset effectively corrects display errors, improving the stability and reliability of the vehicle's instrument system, while also enhancing driver safety and comfort.

[0070] In one exemplary embodiment of the present invention, one implementation of resetting the video output unit, or the video output unit and signal conversion unit, involves acquiring pre-stored correct video image data through the verification unit of the vehicle instrument system and displaying the correct video image data on the vehicle instrument screen of the vehicle instrument system. The video output unit, or the video output unit and signal conversion unit, is then reset. If the video output unit, or the video output unit and signal conversion unit, is successfully reset, new video image output information is acquired through the reset video output unit, and a new first comparison result is obtained through verification; or, new video image output information is acquired through the reset video output unit, and new video image pass-through information is acquired through the reset signal conversion unit, and a new second comparison result is obtained through verification. If the video output unit, or the video output unit and signal conversion unit, fails to reset, an instrument fault warning sound is played, and fault information of the signal link where the video output unit is located, or the signal link where the video output unit and signal conversion unit are located, is reported.

[0071] In practical applications, the verification unit acquires pre-stored correct video image data for display on the vehicle's instrument panel screen. Displaying the correct video image data on the instrument panel screen verifies the operational status of the video output unit or the video output unit and signal conversion unit. If only the video output unit is reset, it is reset after displaying the correct video image data. If both the video output unit and the signal conversion unit are reset simultaneously, both are reset after displaying the correct video image data. Upon successful reset, new video image output information is acquired through the reset video output unit, and a new verification is performed to obtain a new first or second comparison result. If the reset is successful, comparative analysis continues to ensure the accuracy of the displayed information. If the reset fails, an instrument panel fault warning sound is played, and fault information regarding the video output unit or the signal link containing the video output unit and signal conversion unit is reported.

[0072] For example: Suppose the video output unit in the vehicle's instrument cluster system malfunctions, resulting in incorrect displayed information. The verification unit retrieves pre-stored correct video image data and displays it on the instrument cluster screen. Then, the video output unit is reset. If the reset is successful, the new video output information is retrieved from the reset video output unit and compared again to ensure the accuracy of the displayed information.

[0073] This invention, by displaying correct video image data, allows for intuitive verification of the operational status of the video output unit or the video output unit and signal conversion unit. Through a reset process, display errors can be corrected promptly, improving the stability and reliability of the vehicle's instrument system, while simultaneously enhancing the driver's sense of security and comfort.

[0074] In one exemplary embodiment of the present invention, an implementation method for controlling the vehicle instrument system is to determine the abnormality of the signal link where the video output unit, signal conversion unit, and display unit are located based on the first comparison result, the second comparison result, and the third comparison result, and to perform reset processing according to the abnormality. Specifically, when the first comparison result indicates that the original instrument information is the same as the video image output information, the second comparison result indicates that the original instrument information is different from the video image transmission information, and the third comparison result indicates that the instrument display information is the same as or different from the video image output information, a fault is determined in the signal link where the signal conversion unit is located, and the signal conversion unit is then reset.

[0075] In practical applications, analysis is performed based on the results of the first, second, and third comparisons. If the first comparison result indicates that the original instrument information is the same as the video image output information, the second comparison result indicates that the original instrument information is different from the video image transmission information, and the third comparison result indicates that the instrument display information is the same as or different from the video image output information, it indicates that there may be an anomaly in the signal link where the signal conversion unit is located. Based on the analysis results, the probability of a fault in the signal link where the signal conversion unit is located is determined. In the case of a fault in the signal link where the signal conversion unit is located, a reset procedure is performed on the signal conversion unit.

[0076] For example, suppose a fault occurs in the signal link of the signal conversion unit in a vehicle's instrument cluster, causing incorrect display information. After comparative analysis, it is determined that the fault lies in the signal link of the signal conversion unit. In this case, according to the implementation method, the signal conversion unit will be reset to restore normal display function.

[0077] This invention allows for the rapid and accurate identification of signal link anomalies based on comparison results, and the implementation of corresponding measures. Timely reset effectively corrects display errors, improving the stability and reliability of the vehicle's instrument system, while also enhancing driver safety and comfort.

[0078] In one exemplary embodiment of the present invention, one implementation of resetting the signal conversion unit involves resetting the signal conversion unit. If the signal conversion unit is successfully reset, new video image transmission information is obtained through the reset signal conversion unit, and a new second comparison result is verified. If the signal conversion unit fails to reset, an instrument fault warning tone is played, and fault information of the signal link where the signal conversion unit is located is reported.

[0079] In practical applications, the signal conversion unit is reset to restore its normal operating state. If the reset is successful, new video image transmission information is obtained through the reset signal conversion unit, and a new second comparison result is verified. If the reset fails, an instrument fault warning tone is played, and fault information of the signal link where the signal conversion unit is located is reported.

[0080] For example, suppose the signal conversion unit in the vehicle's instrument cluster malfunctions, causing incorrect displayed information. By resetting the signal conversion unit, if the reset is successful, new video image transmission information can be obtained from the reset unit and compared to ensure the accuracy of the displayed information. If the reset fails, a fault tone will play on the instrument cluster, and a fault report will be sent to the signal link containing the signal conversion unit.

[0081] This invention allows for the timely restoration of the signal conversion unit to its normal operating state by resetting it, effectively correcting display errors. Verifying the new video image transmission information ensures the accuracy of the displayed information. If the reset fails, a fault warning sound is played and fault information is reported promptly, facilitating rapid problem location and resolution, and improving system reliability and user experience.

[0082] In one exemplary embodiment of the present invention, an implementation method for controlling the vehicle instrument system is to determine the abnormality of the signal link where the video output unit, signal conversion unit, and display unit are located based on the first comparison result, the second comparison result, and the third comparison result, and to perform reset processing according to the abnormality. Specifically, when the first comparison result indicates that the original instrument information is the same as the video image output information, the second comparison result indicates that the original instrument information is the same as the video image transmission information, and the third comparison result indicates that the instrument display information is different from the video image output information, a fault is determined in the signal link where the display unit is located, and the display unit is then reset.

[0083] In practical applications, analysis is performed based on the results of the first, second, and third comparisons. If the first comparison result indicates that the original instrument information is the same as the video image output information, the second comparison result indicates that the original instrument information is the same as the video image transmission information, and the third comparison result indicates that the instrument display information is different from the video image output information, it indicates that there may be an anomaly in the signal link where the display unit is located. Based on the analysis results, the probability of a fault in the signal link where the display unit is located is determined. In the case of a fault in the signal link where the display unit is located, a reset procedure is performed on the display unit.

[0084] For example, suppose a fault occurs in the signal link of the display unit in a vehicle's instrument cluster, causing incorrect information to be displayed. After comparative analysis, it is determined that the fault lies in the signal link of the display unit. In this case, according to the implementation method, the display unit will be reset to restore normal display function.

[0085] This invention allows for the rapid and accurate identification of signal link anomalies based on comparison results, and the implementation of corresponding measures. Timely reset effectively corrects display errors, improving the stability and reliability of the vehicle's instrument system, while also enhancing driver safety and comfort.

[0086] In one exemplary embodiment of the present invention, one implementation of the reset process for the display unit is to reset the display unit. If the display unit is successfully reset, the reset display unit displays new instrument display information on the vehicle instrument screen, and verifies and obtains a new third comparison result. If the display unit reset fails, an instrument fault warning sound is played, and fault information of the signal link where the display unit is located is reported.

[0087] In practical applications, the display unit is reset to restore its normal operating state. If the reset is successful, the reset display unit displays new instrument information on the vehicle's instrument screen and verifies the new third comparison result. If the reset fails, an instrument fault warning sound is played, and fault information in the signal link where the display unit is located is reported.

[0088] For example, suppose the display unit in the vehicle's instrument cluster malfunctions, causing incorrect information to be displayed. By resetting the display unit, if the reset is successful, new instrument display information can be shown on the vehicle's instrument cluster screen, and the accuracy of the displayed information can be verified. If the reset fails, an instrument cluster fault warning sound will be played, and fault information in the signal link where the display unit is located will be reported.

[0089] This invention, through resetting the display unit, can promptly restore its normal operating state and effectively correct display errors. By displaying new instrument information, the accuracy of the displayed information can be ensured. If the reset fails, a fault warning sound is played and fault information is reported promptly, which helps to quickly locate and resolve problems, improving system reliability and user experience.

[0090] In an exemplary embodiment of the present invention, an implementation may be included in which, when the first comparison result indicates that the original instrument information is different from the video image output information, the second comparison result indicates that the original instrument information is the same as the video image transmission information, and the third comparison result indicates that the instrument display information is the same as or different from the video image output information, a judgment error is determined to have occurred, and the judgment error information is reported.

[0091] In an exemplary embodiment of the present invention, an implementation may be included in which, when the first comparison result indicates that the original instrument information is the same as the video image output information, the second comparison result indicates that the original instrument information is the same as the video image transmission information, and the third comparison result indicates that the instrument display information is the same as the video image output information, the signal link where the video output unit, the signal conversion unit, and the screen display unit are located is normal.

[0092] Based on the above description of an embodiment of a control method for a vehicle instrument system, a smart cockpit instrument safety display scheme is introduced below. This display scheme can be applied to a smart cockpit instrument safety display system. (Refer to...) Figure 2 The diagram illustrates the principle of a smart cockpit instrument safety display scheme according to an embodiment of the present invention.

[0093] This intelligent cockpit instrument safety display system can include the following six parts:

[0094] The first part consists of the video output unit and the display unit:

[0095] The video output unit is mainly responsible for outputting instrument video images. It is generally based on a System On a Chip (SOC) chip. The video output unit generates the video image output information required for the instrument display based on the original instrument information such as vehicle speed and prompt information sent by the control unit through the Controller Area Network (CAN) / Local Interconnect Network (LIN). The video image output information is then sent to the verification unit A.

[0096] The display unit is mainly responsible for converting the received image signals into driving signals for the screen, thereby driving the instrument panel display.

[0097] The second part is the control unit:

[0098] This part is the core of the entire solution. The control unit is generally controlled by a microcontroller (MCU) as the master controller. It is responsible for receiving raw instrument information such as vehicle speed, alarms, status, and indicator lights sent by the vehicle, sending / transmitting the raw instrument information to various units, executing the core algorithm of the solution, controlling the speaker to generate abnormal alarm sounds, and transmitting control signals with the video output unit and verification unit A through the Serial Peripheral Interface (SPI).

[0099] The third part is the verification unit:

[0100] This section mainly consists of verification unit A and verification unit B. Verification unit A is responsible for performing a cyclic redundancy check (CRC) on the video image output information such as vehicle speed and prompts generated by the video output unit and the original instrument information such as vehicle speed provided by the control unit. If the CRC fails, it is determined that the video output unit is abnormal, and the verification result is returned to the algorithm module in the control unit.

[0101] Verification unit B is responsible for performing a CRC check on the vehicle speed, prompts, and other video image transmission information output by signal conversion unit B (transmitted by the video output unit through the signal conversion unit) and the original instrument information such as vehicle speed provided by the control unit. If the CRC fails, it is determined that the link from verification unit B to the video output unit is abnormal, and the verification result is returned to the algorithm module in the control unit.

[0102] The fourth part is the storage unit:

[0103] The storage unit is responsible for storing the graphic data required by the verification unit B. When the link from the verification unit B to the video output unit is abnormal, the verification unit B can retrieve the pre-stored image data from the storage unit based on the original instrument information such as vehicle speed and status, and send it to the display unit to avoid the risk of abnormal instrument display.

[0104] The fifth part is the signal conversion unit:

[0105] The signal conversion unit includes signal conversion unit A and signal conversion unit B. The verification unit, video output unit, and display unit typically use Low Voltage Differential Signaling (LVDS) interfaces. However, for long-distance transmission between the cockpit main unit and cockpit instruments, signal conversion units are generally used to convert LVDS signals into serial data based on the Inter-Integrated Circuit (I2C) serial communication protocol for transmission over coaxial and twisted-pair cables. Signal conversion unit A is responsible for encoding the serial data on the main unit side, and signal conversion unit B is responsible for decoding the serial data on the display side.

[0106] Part 6 is the vehicle-mounted camera unit:

[0107] The vehicle-mounted camera captures instrument display information such as icons, prompts, and vehicle speed from the instrument panel. After image recognition, it compares the information with the pre-stored graphics in the camera (which can output information as video images). The comparison result is then returned to the video output unit via a wireless local area network (Wi-Fi). The video output unit then sends the comparison result to the control unit.

[0108] The core algorithm unit of this display solution is integrated into the MCU. (Refer to...) Figure 3 The diagram shows a schematic representation of the core algorithm flow of an embodiment of the present invention.

[0109] After determining the verification value Y, the core algorithm selects the corresponding execution process based on the preset truth table.

[0110] Reference Figure 4 This illustrates the logical truth value representation of an embodiment of the present invention.

[0111] In the truth table, 0 represents a successful check and 1 represents a failed check. X represents 0 or 1. The truth table has 5 main categories of logic.

[0112] 1. If both verification units A and B fail simultaneously (e.g., 11X), it is determined that the video output unit or both the video output unit and the signal conversion unit have failed. In this case, algorithm flow 1 is executed. (Refer to...) Figure 5 The diagram illustrates the steps of algorithm flow 1 in this embodiment of the invention. First, the verification unit B outputs correct video data to the display unit to ensure the safety of the instrument display. Then, fault handling is performed. First, the video output unit is reset. If this fails, the control unit reports the fault to the fault platform and plays an instrument fault warning sound. If the video output unit fault is resolved by resetting, the process returns to the core algorithm flow to monitor whether other units are abnormal.

[0113] 2.01X, at this point, the core algorithm determines that the signal conversion unit is faulty and executes algorithm flow 2. (Refer to...) Figure 6 The diagram illustrates the steps of algorithm flow 2 in this embodiment of the invention. First, the verification unit B outputs correct video data to the display unit to ensure the safety of the instrument display. Then, the signal conversion unit is reset / restarted. If recovery is successful, the process returns to the main flow for continued monitoring. If resetting / restarting the signal conversion unit fails, the control unit reports the fault to the fault platform and plays an instrument fault warning sound.

[0114] 3,001. This situation is judged as a display unit failure, because verification units A and B are normal. This scenario may be caused by a display system malfunction, resulting in an abnormality in a single pixel on the screen, or even a black screen. See core algorithm execution flow 3. Figure 7 The diagram illustrates the steps of algorithm flow 3 in this embodiment of the invention. The control unit reports the fault to the platform and plays an instrument fault warning sound. After resetting and restarting the display unit software, if the fault is resolved, the process returns to the main flow. If the fault cannot be resolved, the control unit continues to report the fault to the platform and play the instrument fault warning sound to alert the driver.

[0115] 4. 10X, this situation is not expected because if verification unit A fails, verification unit B will definitely fail. Therefore, it is very likely that a judgment error has occurred, and it needs to be reported to the platform for resolution.

[0116] In the case of 5,000, the core algorithm determines that each unit is normal, performs no operation, and continues monitoring.
