[0002] With continuous economic development and rising living standards, cars are becoming increasingly common in households and are becoming an increasingly important tool for daily life. Furthermore, with the advancement of science and technology and the popularization of intelligent technology, intelligent instrument displays are becoming standard equipment in more and more car models, and this trend of replacing traditional screens with intelligent displays is unstoppable and will become increasingly widespread.

[0003] Currently, automotive instrument panel displays primarily employ a single-display system. This system can detect when to switch displays, switch displays, and restart the system from a system operation perspective, providing reliable redundancy for the instrument panel display. However, when the entire or some nodes or links of the vehicle's signal input to the display malfunction, causing display errors without throwing an exception or resetting, the single-display system cannot effectively detect and resolve the anomaly, resulting in abnormal vehicle display content. Summary of the Invention

[0008] The display monitoring and control system determines whether a target display system is operating normally in the first display system and the second display system based on the first front CRC check value, the second front CRC check value, the first rear CRC check value, and the second rear CRC check value.

[0009] If the target display system exists, the display monitoring and control system sets the first display system or the second display system in the target display system as the main display system, and sets the first display system and another display system in the second display system as backup display systems.

[0010] The display monitoring and control system controls the display data verification and selection system to send the data corresponding to the main display system to the vehicle's display screen for display.

[0011] Furthermore, after determining whether a normally functioning target display system exists in the first display system and the second display system, the method further includes:

[0012] If the target display system does not exist, the display monitoring and control system updates the first retransmission count corresponding to the first display system and the second retransmission count corresponding to the second display system.

[0018] If the updated third retransmission count does not reach the preset retransmission count, the display monitoring and control system sends a retransmission signal to the first abnormal display system.

[0019] If the updated third retransmission count reaches the preset retransmission count, the display monitoring and control system sends a reset control signal to the first abnormal display system.

[0025] Upon receiving the first or second pre-CRC check value, the display monitoring and control system sends a control signal for the data receiving status of the first or second display system to the display data verification and selection system.

[0026] If the first data or the second data is received when the duration after receiving the control signal reaches a first preset duration, the display data verification selection system generates the first post-CRC check value based on the first data, or generates the second post-CRC check value based on the second data.

[0027] Furthermore, after the step of the display monitoring and control system sending a control signal of the data receiving status to the display data verification and selection system, the method further includes:

[0040] Furthermore, after the step of the display monitoring and control system controlling the display data verification and selection system to send the data corresponding to the target display system to the vehicle's display screen for display if the target display system exists, the system further includes:

[0041] If no enable control signal from the display monitoring and control system is received within a fourth preset time period after the third data sent by the target display system, the display data verification and selection system will send the third data to the display screen for display. The enable control signal is used to enable the display data verification and selection system to send the third data to the display screen.

[0042] Furthermore, after the step of the display data verification and selection system sending the third data to the display screen for display, the system further includes:

[0043] The displayed data verification selects the number of times the system update has not been enabled.

[0044] If the updated number of times the enable signal is not received reaches the preset number, the display data verification and selection system sends a reset signal to the display monitoring and control system.

[0059] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0060] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a vehicle display device in the hardware operating environment involved in the embodiments of this application.

[0061] The vehicle display device in this application embodiment can be a vehicle. For example... Figure 1 As shown, the vehicle display device may include: a processor 1001, such as a CPU; a network interface 1004; a user interface 1003; a memory 1005; and a communication bus 1002. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen and an input unit such as a keyboard. Optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be high-speed RAM or non-volatile memory, such as a disk drive. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0062] Optionally, the vehicle display device may also include a camera, RF (Radio Frequency) circuitry, sensors, audio circuitry, a WiFi module, and so on. These sensors may include, for example, light sensors, motion sensors, and other sensors. Of course, the vehicle display device may also be equipped with other sensors such as gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, which will not be elaborated upon here.

[0063] Those skilled in the art will understand that Figure 1 The terminal structure shown does not constitute a limitation on the vehicle display device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0064] like Figure 1 As shown, the memory 1005, which serves as a computer storage medium, may include an operating system, a network communication module, a user interface module, and a vehicle display program.

[0065] exist Figure 1 In the vehicle display device shown, the network interface 1004 is mainly used to connect to the backend server and communicate data with the backend server; the user interface 1003 is mainly used to connect to the client (user terminal) and communicate data with the client; and the processor 1001 can be used to call the vehicle display program stored in the memory 1005.

[0066] In this embodiment, the vehicle display device includes: a memory 1005, a processor 1001, and a vehicle display program stored in the memory 1005 and executable on the processor 1001. When the processor 1001 calls the vehicle display program stored in the memory 1005, it executes the steps of the vehicle display method in the following embodiments.

[0067] This application also provides a vehicle display method, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the vehicle display method of this application.

[0068] Reference Figure 3 The vehicle includes a first display system 10, a second display system 20, a display monitoring and control system 40, a display data verification and selection system 30, and a display screen 50.

[0069] Among them, reference Figure 3 The first and second display systems are functionally identical and have comparable performance. They can be completely identical hardware and software systems, or they can have different hardware but identical software (implementation methods can be the same or different) input and output. Both systems receive the same input signal and output a display signal to the display screen (the vehicle's intelligent instrument display screen) to drive the screen to display the desired content. Both the first and second display systems may include an input signal and data processing display application module, a CRC checksum calculation and transmission module, a retransmission and reset processing module, and a display output module, etc. Figure 3 In this module, module 1 is the input signal and data processing and display application module, module 2 is the front CRC check value calculation and transmission module, module 3 is the retransmission and reset processing module, and module 4 is the display output module. In actual implementation, each functional module may be completed by a functional unit, or the function of a module may be implemented by multiple sub-module units, or multiple units may cross-implement multiple sub-module functions.

[0070] The input signal and data processing display application module receives input signals from the ECU, such as shift signals, speed data, mileage data, door opening signals, and seat belt unfastened signals. It also receives input signals from the vehicle's central control unit, such as navigation information, music information, and reversing camera data.

[0071] Before or simultaneously with outputting display signals (data) to the screen, the first and second display systems calculate the CRC value (pre-CRC checksum) of the display signals and send it to the display monitoring and control system. The data can be sent frame by frame, line by line, or pixel by pixel. The calculation and transmission of the pre-CRC checksum is handled by the pre-CRC checksum calculation and transmission module. CRC calculation can be implemented using software algorithms or purely hardware circuitry. The CRC value can be calculated based on the display signal (frame / line synchronization control signal, data signal, etc.); it can be calculated per frame of display data, per line of display data, or per pixel; or it can be calculated by selecting specific data from a transmitted data segment according to a set rule.

[0072] The retransmission and reset processing module receives retransmission and reset signals from the display monitoring and control system. Upon receiving a retransmission signal, the display system needs to re-prepare the most recently sent display data and calculate the corresponding CRC value. The display data is sent to the display data verification and selection system, and the CRC checksum is sent to the display monitoring and control system via the display output module and the CRC checksum calculation and transmission module, respectively. Upon receiving a reset signal, the display system needs to directly reset, restart the application, and re-output the display data and corresponding CRC checksum based on the system input signals.

[0073] The display output module functions similarly to the display control and output peripheral modules of common systems. It is responsible for sending display data to the display selection switch and control system according to the interface timing specifications. The interface can be any common video output interface conforming to general specifications, such as digital video output interface, LVDS interface, HDMI, DP, etc. It can also be a serial or parallel peripheral interface that meets timing requirements, or a wired or wireless network communication interface.

[0074] The output interfaces from the display data verification and selection system to the display screen include all common video output interfaces conforming to general specifications, such as analog video output interfaces, digital video output interfaces, LVDS interfaces, HDMI, and DP. They can also be serial or parallel peripheral interfaces that meet the timing requirements of the display screen. The display data verification and selection system controls the display timing and display parameters through signals received from the display system, through control inputs from the display monitoring and control system, or through default settings (or programmable control, or hardware design).

[0075] The vehicle display method includes:

[0076] Step S101: The first display system sends the first front CRC check value corresponding to the first data to the display monitoring and control system, and the second display system sends the second front CRC check value corresponding to the second data to the display monitoring and control system.

[0077] When the first display system receives the input data to be displayed, the first display system generates or calculates the corresponding first CRC check value based on the first data (input data), and sends the first CRC check value to the display monitoring and control system. At the same time, the first display system can also send the first data to the display data verification and selection system.

[0078] When the second display system receives the input data to be displayed, the second display system generates or calculates the corresponding second front CRC check value based on the second data (input data), and sends the second front CRC check value to the display monitoring and control system. At the same time, the second display system can also send the second data to the display data verification and selection system.

[0079] The first and second data are the same input data. This input data can include ECU shift signals, speed data, mileage data, door opening signals, seat belt unfastened signals, navigation information sent by the vehicle's central control system, music information, and reversing camera data, etc.

[0080] Step S102: The display data verification selection system sends the first post-CRC check value corresponding to the first data and the second post-CRC check value corresponding to the second data to the display monitoring and control system.

[0081] When the display data verification selection system receives the first data sent by the first display system, it generates or calculates the first post-CRC check value based on the first data and sends the first post-CRC check value to the display monitoring and control system.

[0082] Simultaneously, when the display data verification selection system receives the second data sent by the second display system, it generates or calculates the second post-CRC check value based on the first data, and sends the second post-CRC check value to the display monitoring and control system.

[0083] It should be noted that the display data verification selection system can also send the first and second post-CRC check values ​​to the display monitoring and control system according to the request of the display monitoring and control system.

[0084] Step S103: The display monitoring and control system determines whether a target display system is operating normally in the first display system and the second display system based on the first front CRC check value, the second front CRC check value, the first back CRC check value, and the second back CRC check value.

[0085] The display monitoring and control system receives a first pre-CRC checksum sent by the first display system and a second pre-CRC checksum sent by the second display system, and also receives a first post-CRC checksum and a second post-CRC checksum sent by the display data verification and selection system. Next, based on the first pre-CRC checksum, the second pre-CRC checksum, the first post-CRC checksum, and the second post-CRC checksum, the display monitoring and control system determines whether a normally functioning target display system exists in the first and second display systems. Specifically, in one possible implementation, step S103 includes:

[0086] The display monitoring and control system determines whether the first front CRC check value matches the first rear CRC check value, and / or determines whether the second front CRC check value matches the second rear CRC check value;

[0087] If the first pre-CRC check value matches the first post-CRC check value, and / or the second pre-CRC check value matches the second post-CRC check value, then the display monitoring and control system determines that the target display system exists.

[0088] Specifically, the display monitoring and control system determines whether the first preceding CRC check value matches the first following CRC check value, i.e., whether the first preceding CRC check value and the first following CRC check value are the same. At the same time, the display monitoring and control system determines whether the second preceding CRC check value matches the second following CRC check value, i.e., whether the second preceding CRC check value and the second following CRC check value are the same. If the first preceding CRC check value matches the first following CRC check value, and / or if the second preceding CRC check value matches the second following CRC check value, i.e., the first preceding CRC check value and the first following CRC check value are the same, and / or if the second preceding CRC check value and the second following CRC check value are the same, then the display monitoring and control system determines that a target display system exists. Specifically, if the first preceding CRC checksum is the same as the first following CRC checksum, and the second preceding CRC checksum is different from the second following CRC checksum, then the display monitoring and control system determines the first display system as the target display system; if the first preceding CRC checksum is different from the first following CRC checksum, and the second preceding CRC checksum is the same as the second following CRC checksum, then the display monitoring and control system determines the second display system as the target display system; if the first preceding CRC checksum is the same as the first following CRC checksum, and the second preceding CRC checksum is the same as the second following CRC checksum, then the display monitoring and control system determines both the first display system and the second display system as target display systems.

[0089] Step S104: If the target display system exists, the display monitoring and control system sets the first display system or the second display system in the target display system as the main display system, and sets the first display system and another display system in the second display system as backup display systems.

[0090] In step S105, the display monitoring and control system controls the display data verification and selection system to send the data corresponding to the main display system to the vehicle's display screen for display.

[0091] After system initialization, if a target display system exists in both the first and second display systems, the display monitoring and control system sets either the first or second display system within the target display system as the primary display system, and sets the first display system and the other display system in the second display system as backup display systems. Specifically, if the target display system includes only the first or second display system, the display monitoring and control system sets the target display system as the primary display system, and sets the first display system and the other display system in the second display system as backup display systems. When the target display system includes both a first display system and a second display system, the display monitoring and control system receives the first pre-CRC checksum, the second pre-CRC checksum, the first post-CRC checksum, and the second post-CRC checksum at different times. Therefore, when matching CRC checksums, the first completion time for matching the first pre-CRC checksum with the first post-CRC checksum is different from the second completion time for matching the second pre-CRC checksum with the second post-CRC checksum. Thus, the display monitoring and control system can first obtain the first and second completion times of the checksums, calculate the first time difference between the first completion time and the current time, and the second time difference between the second completion time and the current time. If the first time difference is greater than the second time difference, the first display system is set as the main display system, and the second display system is set as the backup display system. If the first time difference is less than or equal to the second time difference, the display monitoring and control system sets the second display system as the main display system and the first display system as the backup display system. This allows the display system that completes the CRC checksum first to be used as the main display system, ensuring that the data transmission path of the main display system is superior to that of the backup display system.

[0092] Next, the display monitoring and control system controls the display data verification and selection system to send the data corresponding to the main display system to the vehicle's display screen for display. Specifically, the display monitoring and control system sends a sending command corresponding to the main display system to the display data verification and selection system, which then sends the data corresponding to the main display system to the vehicle's display screen according to the sending command.

[0093] The first display system sends a first pre-CRC checksum corresponding to the first data to the display monitoring and control system, and the second display system sends a second pre-CRC checksum corresponding to the second data to the display monitoring and control system. Then, the display data verification selection system sends a first post-CRC checksum corresponding to the first data and a second post-CRC checksum corresponding to the second data to the display monitoring and control system. Subsequently, the display monitoring and control system, based on the first pre-CRC checksum, the second pre-CRC checksum, the first post-CRC checksum, and the second post-CRC checksum, determines whether a normally functioning target display system exists in the first and second display systems. If the target display system exists, the display monitoring and control system then... The first display system or the second display system is set as the main display system, and another display system in the first display system and the second display system is set as a backup display system. The display monitoring and control system controls the display data verification and selection system to send the data corresponding to the main display system to the vehicle's display screen for display. The dual display system of the first display system and the second display system realizes display output backup, which improves the accuracy and reliability of vehicle display and reduces the probability of display abnormalities. The presence of abnormalities in the dual display system is determined by the CRC check value to realize the abnormal detection of display data. Compared with the abnormal detection through system operation, it solves the problem of display abnormalities caused by system abnormalities, application abnormalities or transmission link abnormalities, and further improves the accuracy and reliability of vehicle display.

[0094] Based on the first embodiment, a second embodiment of the vehicle display method of this application is proposed, wherein after step S103, the vehicle display method further includes:

[0095] Step S201: If the target display system does not exist, the display monitoring and control system updates the first retransmission count corresponding to the first display system and the second retransmission count corresponding to the second display system.

[0096] Step S202: If the updated first retransmission count does not reach the preset retransmission count, the display monitoring and control system sends a retransmission signal to the first display system, and / or, if the updated second retransmission count does not reach the preset retransmission count, the display monitoring and control system sends a retransmission signal to the second display system.

[0097] Step S203: If the updated first retransmission count reaches the preset retransmission count, the display monitoring and control system sends a reset control signal to the first display system, and the first display system performs a reset operation based on the reset control signal; and / or, if the updated second retransmission count reaches the preset retransmission count, the display monitoring and control system sends a reset control signal to the second display system, and the second display system performs a reset operation based on the reset control signal.

[0098] If the target display system does not exist, that is, the first front CRC check value does not match the first back CRC check value, and the second front CRC check value does not match the second back CRC check value, then the display monitoring and control system updates the first retransmission count corresponding to the first display system and the second retransmission count corresponding to the second display system; that is, the first retransmission count is added by 1 to obtain the updated first retransmission count, and the second retransmission count is added by 1 to obtain the updated second retransmission count.

[0099] Next, the display monitoring and control system determines whether the updated first retransmission count has reached the preset retransmission count, and whether the updated second retransmission count has reached the preset retransmission count.

[0100] If the updated first retransmission count does not reach the preset retransmission count, the display monitoring and control system sends a retransmission signal to the first display system. Simultaneously, the display data verification and selection system clears the first data according to the control command of the display monitoring and control system. The first display system then sends the first data to the display data verification and selection system based on the retransmission signal. Alternatively, if the updated second retransmission count does not reach the preset retransmission count, the display monitoring and control system sends a retransmission signal to the second display system. Simultaneously, the display data verification and selection system clears the second data according to the control command of the display monitoring and control system. The second display system then sends the second data to the display data verification and selection system based on the retransmission signal. Then, step S101 is executed.

[0101] If the updated first retransmission count reaches the preset retransmission count, the display monitoring and control system sends a reset control signal to the first display system. Simultaneously, the display data verification and selection system clears the first data according to the control command of the display monitoring and control system. The first display system performs a reset operation based on the reset control signal. And / or, if the updated second retransmission count reaches the preset retransmission count, the display monitoring and control system sends a reset control signal to the second display system. Simultaneously, the display data verification and selection system clears the second data according to the control command of the display monitoring and control system. The second display system performs a reset operation based on the reset control signal. Then, step S101 is executed.

[0102] The preset number of retransmissions can be set reasonably, for example, the preset number of retransmissions can be 3 or 5.

[0103] If the target display system does not exist, the display monitoring and control system updates the first retransmission count corresponding to the first display system and the second retransmission count corresponding to the second display system. Then, if the updated first retransmission count does not reach the preset retransmission count, the display monitoring and control system sends a retransmission signal to the first display system, and / or, if the updated second retransmission count does not reach the preset retransmission count, the display monitoring and control system sends a retransmission signal to the second display system. Subsequently, if the updated first retransmission count reaches the preset retransmission count, the display monitoring and control system sends a reset control signal to the first display system, and the first display system performs a reset operation based on the reset control signal. And / or, if the updated second retransmission count reaches the preset retransmission count, the display monitoring and control system sends a reset control signal to the second display system, and the second display system performs a reset operation based on the reset control signal. This allows for retransmission or reset of the first and second display systems based on the retransmission count, effectively resolving anomalies in either the first or second display system and further improving the accuracy and reliability of vehicle displays.

[0104] Based on the first embodiment, a third embodiment of the vehicle display method of this application is proposed, wherein step S104 includes:

[0105] Step S301: If the target display system is the first display system or the second display system, the display monitoring and control system controls the display data verification and selection system to send the data corresponding to the target display system to the vehicle's display screen for display.

[0106] Step S302: The display monitoring and control system determines the first abnormal display system in the first display system and the second display system, and updates the third retransmission number corresponding to the first abnormal display system.

[0107] Step S303: If the updated third retransmission count does not reach the preset retransmission count, the display monitoring and control system sends a retransmission signal to the first abnormal display system.

[0108] Step S304: If the updated third retransmission count reaches the preset retransmission count, the display monitoring and control system sends a reset control signal to the first abnormal display system.

[0109] If a target display system exists in both the first and second display systems, the display monitoring and control system first determines whether the target display system is the first or the second display system. If the target display system is either the first or the second display system, the display monitoring and control system controls the display data verification and selection system to send the data corresponding to the target display system to the vehicle's display screen for display. Specifically, the display monitoring and control system sends a sending command corresponding to the target display system to the display data verification and selection system, which then sends the data corresponding to the target display system to the vehicle's display screen according to the sending command. At the same time, the display data verification and selection system can also clear the caches of the first and second data.

[0110] Next, the display monitoring and control system identifies the first abnormal display system among the first display system and the second display system, that is, the first abnormal display system among the first display system and the other display system in the second display system besides the target display system, and updates the third retransmission count corresponding to the first abnormal display system. Specifically, it obtains the third retransmission count corresponding to the first abnormal display system, updates the third retransmission count by incrementing it by 1, and determines whether the updated third retransmission count reaches the preset retransmission count.

[0111] If the updated third retransmission count does not reach the preset retransmission count, the display monitoring and control system sends a retransmission signal to the first abnormal display system; the first abnormal display system sends corresponding data to the display data verification and selection system based on the retransmission signal. If the updated third retransmission count reaches the preset retransmission count, the display monitoring and control system sends a reset control signal to the first abnormal display system, and the first abnormal display system performs a reset operation based on the reset control signal.

[0112] The preset number of retransmissions can be set reasonably, for example, the preset number of retransmissions can be 3 or 5.

[0113] If the target display system is either the first display system or the second display system, the display monitoring and control system controls the display data verification and selection system to send the data corresponding to the target display system to the vehicle's display screen for display. Then, the display monitoring and control system identifies the first abnormal display system among the first and second display systems and updates the third retransmission count corresponding to the first abnormal display system. If the updated third retransmission count does not reach the preset retransmission count, the display monitoring and control system sends a retransmission signal to the first abnormal display system. If the updated third retransmission count reaches the preset retransmission count, the display monitoring and control system sends a reset control signal to the first abnormal display system. This allows for retransmission or reset of the first or second display system while the display screen is displaying normally, effectively resolving abnormalities in the first or second display system and further improving the accuracy and reliability of the vehicle display.

[0114] Based on the first embodiment, a fourth embodiment of the vehicle display method of this application is proposed, wherein the vehicle display method further includes:

[0115] Step S401: The first display system sends the first data to the display data verification and selection system, and the second display system sends the second data to the display data verification and selection system;

[0116] Step S402: When the first pre-CRC check value or the second pre-CRC check value is received, the display monitoring and control system sends a control signal for the data receiving status corresponding to the first display system or the second display system to the display data verification and selection system.

[0117] Step S403: If the first data or the second data is received when the duration after receiving the control signal reaches a first preset duration, the display data verification selection system generates the first post-CRC check value based on the first data, or generates the second post-CRC check value based on the second data.

[0118] When the first display system receives the input data to be displayed, it can also send the first data to the display data verification and selection system; or, when the second display system receives the input data to be displayed, it can also send the second data to the display data verification and selection system.

[0119] The display monitoring and control system receives a first front CRC check value sent by the first display system or a second front CRC check value sent by the second display system. Upon receiving the first front CRC check value or the second front CRC check value, the display monitoring and control system sends a control signal for the data receiving status of the first display system or the second display system to the display data verification and selection system.

[0120] When a control signal is received, the display data verification selection system determines whether first data or second data is received when the duration after receiving the control signal reaches a first preset duration. If first data or second data is received, the display data verification selection system generates a first post-CRC check value based on the first data and generates a second post-CRC check value based on the second data, or sends the first post-CRC check value and the second post-CRC check value to the display monitoring and control system.

[0121] The first preset duration can be set reasonably, for example, the first preset duration is 1 millisecond, 3 milliseconds, etc.

[0122] The first display system sends the first data to the display data verification and selection system, and the second display system sends the second data to the display data verification and selection system. Then, upon receiving the first or second pre-CRC checksum, the display monitoring and control system sends a control signal indicating the data receiving status of the first or second display system to the display data verification and selection system. If the first or second data is received after a first preset duration following the receipt of the control signal, the display data verification and selection system generates the first post-CRC checksum based on the first data, or the second post-CRC checksum based on the second data. By setting the first preset duration, the system detects whether there are any abnormalities in the display data verification and selection system and the display monitoring and control system, thereby further improving the accuracy and reliability of the vehicle display.

[0123] Based on the fourth embodiment, a fifth embodiment of the vehicle display method of this application is proposed, wherein, after step S402, the vehicle display method further includes:

[0124] Step S501: If the display data verification selection system fails to receive the first data and / or the second data within a first preset duration after receiving the control signal, the display monitoring and control system determines that the second abnormal display system is abnormal.

[0125] In step S502, the display monitoring and control system sends a retransmission signal to the second abnormal display system.

[0126] If the display data verification selection system fails to receive the first data and / or the second data for a duration equal to a first preset duration after receiving the control signal, the display monitoring and control system determines a second abnormal display system. Specifically, when the first data and / or the second data are not received for a duration equal to the first preset duration, the display data verification selection system sends...

[0127] If the failure to receive the first data and / or the second data is sent to the display monitoring and control system, and the failure to receive the first data is not received, then the first display system is determined to be the second abnormal display system. If the failure to receive the second data is not received, then the second display system is determined to be the second abnormal display system. If the failure to receive the first data and the second data are both not received, then both the first display system and the second display system are determined to be the second abnormal display system.

[0128] Next, the display monitoring and control system sends a retransmission signal to the second abnormal display system. The second abnormal display system retransmits the data according to the retransmission signal. Specifically, if the first display system is the second abnormal display system, the first display system retransmits the first data to the display data verification and selection system according to the retransmission signal. If the second display system is the second abnormal display system, the second display system retransmits the second data to the display data verification and selection system according to the retransmission signal. If both the first and second display systems are the second abnormal display systems, the first display system retransmits the first data to the display data verification and selection system according to the retransmission signal, and the second display system retransmits the second data to the display data verification and selection system according to the retransmission signal.

[0129] If the display data verification selection system fails to receive the first data and / or the second data within a first preset time after receiving the control signal, the display monitoring and control system determines that a second abnormal display system has been identified. Then, the display monitoring and control system sends a retransmission signal to the second abnormal display system. This allows the first display system and / or the second display system to retransmit data when the display data verification selection system cannot receive the first data and / or the second data in a timely manner, thereby further improving the accuracy and reliability of the vehicle display.

[0130] Based on the fourth embodiment, a sixth embodiment of the vehicle display method of this application is proposed, wherein after step S402, the vehicle display method further includes:

[0131] Step S601: If no feedback information corresponding to the control signal is received after the control signal has been sent for a duration of a second preset duration, the display monitoring and control system sends a reset signal to the display data verification and selection system.

[0132] In step S602, the display data verification and selection system performs a reset operation based on the reset signal, and sends a retransmission signal to the first display system and the second display system when the reset operation is completed.

[0133] After sending the control signal, the display monitoring and control system determines in real time whether feedback information corresponding to the control signal is received within a second preset time period after the control signal is sent. If no feedback information corresponding to the control signal is received, the display monitoring and control system sends a reset signal to the display data verification and selection system. The display data verification and selection system performs a reset operation based on the reset signal, and sends a retransmission signal to the first display system and the second display system when the reset operation is completed.

[0134] After receiving the retransmission signal, the first display system and the second display system retransmit the first data and the second data to the display data verification and selection system, respectively, and retransmit the first previous CRC check value and the second previous CRC check value to the display monitoring and control system, respectively.

[0135] If no feedback information corresponding to the control signal is received after the control signal has been sent for a period of time that is a second preset duration, the display monitoring and control system sends a reset signal to the display data verification and selection system. Then, the display data verification and selection system performs a reset operation based on the reset signal, and sends a retransmission signal to the first display system or the second display system when the reset operation is completed. This can reset the display data verification and selection system when it is abnormal, further improving the accuracy and reliability of the vehicle display.

[0136] Based on the fourth embodiment, a seventh embodiment of the vehicle display method of this application is proposed, wherein after step S401, the vehicle display method further includes:

[0137] Step S701: The display data verification and selection system receives the first data or the second data;

[0138] Step S702: If the control signal is not received within a third preset time period after the first data or the second data is received, the display data verification and selection system sends the first data or the second data to the vehicle's display screen for display.

[0139] The display data verification selection system receives the first data or the second data, and within a third preset time period after receiving the first data or the second data, determines whether a control signal has been received. If the control signal is not received, the display data verification selection system sends the first data or the second data to the vehicle's display screen for display.

[0140] Specifically, the display data verification and selection system determines the data to be sent from the first data or the second data based on the data previously sent to the display screen. For example, if the data previously sent to the display screen was sent by the first display system, the display data verification and selection system sends the first data to the display screen for display. If the data previously sent to the display screen was sent by the second display system, the display data verification and selection system sends the second data to the display screen for display, so as to ensure the real-time display of vehicle data.

[0141] Furthermore, in one possible implementation, after step S702, the vehicle display method further includes:

[0142] Step S703: The display data verification selects the number of system update timeouts;

[0143] Step S704: If the updated timeout count reaches the preset timeout count, the display data verification and selection system sends a reset signal to the display monitoring and control system.

[0144] In step S705, the display monitoring and control system performs a reset operation based on the reset information.

[0145] After sending the first or second data to the display screen, the display data verification selection system updates the timeout count and determines whether the updated timeout count reaches the preset timeout count. If the updated timeout count reaches the preset timeout count, the display data verification selection system sends a reset signal to the display monitoring and control system. The display monitoring and control system performs a reset operation based on the reset information, thereby resetting the display monitoring and control system when the display data verification selection system cannot receive control signals from the display monitoring and control system, further improving the accuracy and reliability of the vehicle display.

[0146] The preset timeout number can be set reasonably, for example, the preset timeout number can be 3 or 5.

[0147] The display data verification and selection system receives the first data or the second data; then, if no control signal is received within a third preset time period after receiving the first data or the second data, the display data verification and selection system sends the first data or the second data to the vehicle's display screen for display, so as to achieve timely display of vehicle data.

[0148] Based on the above embodiments, an eighth embodiment of the vehicle display method of this application is proposed, wherein after step S104, the vehicle display method further includes:

[0149] Step S801: If no enable control signal from the display monitoring and control system is received within a fourth preset time period after receiving the third data sent by the target display system, the display data verification and selection system will send the third data to the display screen for display. The enable control signal is used to enable the display data verification and selection system to send the third data to the display screen.

[0150] Generally, after selecting a target display system, when displaying data from the target display system, the data from the target display system is preferentially sent to the display screen for display. Upon receiving the third data sent by the target display system, the display data verification and selection system determines in real time whether it receives the enable control signal from the display monitoring and control system within a fourth preset time period after receiving the third data. If the enable control signal is not received, the display data verification and selection system sends the third data to the display screen for display. If the enable control signal is received, the display data verification and selection system sends the data corresponding to the enable control signal to the display screen for display. In other words, the enable control signal is used to cause the display data verification and selection system to send the third data to the display screen.

[0151] Furthermore, in one possible implementation, after step S801, the vehicle display method further includes:

[0152] Step S802, the number of times the display data verification selection system update has not been enabled;

[0153] Step S803: If the updated number of times the enable signal is not received reaches a preset number, the display data verification and selection system sends a reset signal to the display monitoring and control system.

[0154] In step S804, the display monitoring and control system performs a reset operation based on the reset information.

[0155] When sending third data to the display screen for display, the display data verification selection system updates the number of times the enable signal has not been received and determines whether the updated number of times the enable signal has not been received reaches a preset number. If the updated number of times the enable signal has not been received reaches the preset number, the display data verification selection system sends a reset signal to the display monitoring and control system. The display monitoring and control system performs a reset operation based on the reset information to reset the display monitoring and control system when the display data verification selection system cannot receive the enable control signal from the display monitoring and control system, thereby further improving the accuracy and reliability of the vehicle display.

[0156] If, within a fourth preset time period after receiving the third data sent by the target display system, no enable control signal is received from the display monitoring and control system, the display data verification and selection system will send the third data to the display screen for display. The enable control signal is used to cause the display data verification and selection system to send the third data to the display screen. By sending the third data to the display screen for display without receiving the enable control signal, timely display of vehicle data can be achieved.

[0157] In addition, this application also proposes a vehicle, referring to Figure 4 The vehicle includes: a first display system 110, a second display system 120, a display monitoring and control system 140, and a display data verification and selection system 130, wherein...

[0158] The first display system 110 is used to send the first front CRC check value corresponding to the first data to the display monitoring and control system;

[0159] The second display system 120 is used to send the second front CRC check value corresponding to the second data to the display monitoring and control system;

[0160] The display data verification and selection system 130 is used to send the first post-CRC check value corresponding to the first data and the second post-CRC check value corresponding to the second data to the display monitoring and control system.

[0161] The display monitoring and control system 140 is used to determine whether a target display system is operating normally in the first display system and the second display system based on the first front CRC check value, the second front CRC check value, the first rear CRC check value, and the second rear CRC check value; if the target display system exists, the first display system or the second display system in the target display system is set as the main display system, and the other display system in the first display system and the second display system is set as a backup display system, and the display data verification and selection system is controlled to send the data corresponding to the main display system to the vehicle's display screen for display.
