Description
Technical Field
[0001] The present invention belongs to the field of vehicle control technology, and in particular, relates to a vehicle multi-screen joint display method, system, vehicle and storage medium. Background Art
[0002] With the rapid development of the automobile industry, the level of automobile intelligence and informationization is getting higher and higher, and the user's usage scenarios of automobiles are becoming more and more diverse.

[0033] Figure 1 is a flow chart of a vehicle multi-screen joint display method according to one embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:
[0034] Step S101 , in response to a vehicle start signal, controlling the instrument panel to display an image processed by a micro control unit.
[0035] Step S102, in response to the system chip being successfully started and outputting display content to the instrument screen, controlling the instrument screen to switch to the image output by the system chip, wherein the instrument screen is connected to the micro control unit and the system chip at the same time.
[0036] Step S103, using the micro control unit to continuously monitor the state of the system-level chip, and in response to a failure or freeze of the system-level chip, controlling the instrument screen to switch back to the display content output by the control unit.
[0037] Specifically, at the initial start of the vehicle, even if the system-level chip has not yet been fully started, the driver can see the key driving information provided by the microcontroller unit, which enhances the safety of the vehicle startup phase. Application scenarios include commercial vehicles, buses, trucks and other vehicles that need to start quickly and obtain driving information immediately.
[0038] In an embodiment of the present invention, in response to a vehicle start signal, the instrument screen is controlled to display an image processed by a micro control unit; in response to the system chip successfully starting up and outputting display content to the instrument screen, the instrument screen is controlled to switch to the image output by the system chip, wherein the instrument screen is simultaneously connected to the micro control unit and the system chip; the micro control unit is used to continuously monitor the state of the system chip, and in response to a failure or freeze of the system chip, the instrument screen is controlled to switch back to the display content output by the control unit. The scheme of the present invention ensures the stability and safety of the initial display by giving priority to the micro control unit to output the display content when the vehicle starts. When the system chip is working normally, the instrument screen can switch to a richer and more intuitive display interface, improving the user experience. At the same time, the micro control unit continuously monitors the state of the system chip, and can quickly switch back to the display content output by the micro control unit when the system chip fails or freezes, ensuring the continuity and reliability of driving information, effectively avoiding the interruption of information display caused by system failure, and improving driving safety. In addition, the use of monitoring methods such as heartbeat detection and error code analysis has enhanced the system's fault detection capabilities, making the multi-screen joint display system more widely used in commercial vehicles, providing drivers with a more intelligent, safe and convenient driving environment, and thus solving the technical problem in related technologies that when the SOC fails, it will directly cause the instrument to not display content.
[0039] Optionally, the system-level chip adopts the Android system.
[0040] Specifically, the Android system, due to its openness and rich application ecosystem, can provide a more complex and intuitive display interface for the instrument panel, such as map navigation, multimedia entertainment, etc., greatly improving the driver's experience. Application scenarios include long-distance transportation, tourist buses, city buses and other vehicles that require rich information display.
[0041] Optionally, the microcontroller outputs display content to the instrument screen when no system-on-chip message is received, stops outputting after receiving the system-on-chip message, and restarts outputting after the system-on-chip message times out.
[0042] Specifically, when the system-level chip fails to work properly, the microcontroller unit can immediately take over and output basic driving information, avoiding interruptions in information display and improving driving safety. Application scenarios include extreme weather, complex road conditions and other environments that may affect the normal operation of the system-level chip.
[0043] Optionally, the system-level chip and the control unit communicate messages through the in-vehicle gateway to ensure that the other party's status can be identified in a timely manner.
[0044] Specifically, the in-vehicle gateway, as a bridge for information exchange, can monitor the status of the system-level chip and microcontroller unit in real time. Once an abnormality is detected, measures can be taken immediately to enhance the stability and response speed of the system. Application scenarios include fleet management, remote monitoring, and other scenarios that require real-time monitoring of vehicle status.
[0045] Optionally, the content output by the microcontroller unit is displayed preferentially when the vehicle is started.
[0046] For example, the content output by the microcontroller unit usually includes basic vehicle information and driving warnings, which are crucial for the driver. Priority display can ensure that the driver obtains this information in the first place, improving driving safety and efficiency. Application scenarios include vehicle start-up in emergency situations, such as emergency evacuation in the event of disasters such as fire and earthquake.
[0047] Optionally, after the system-level chip is started, it outputs display content to the instrument screen and sends a status message through the gateway.
[0048] Specifically, the sending of status messages not only confirms the normal operation of the system-level chip, but also provides the health status information of the system-level chip, which helps the microcontroller unit make more accurate switching decisions. Application scenarios include daily maintenance and fault diagnosis of vehicles. Status messages can quickly locate problems and reduce maintenance time.
[0049] Optionally, a microcontroller unit is used to continuously monitor the status of the system-on-chip, including: heartbeat detection and error code analysis.
[0050] Specifically, heartbeat detection and error code analysis are effective means of monitoring the status of system-level chips, which can detect potential faults in a timely manner, take preventive measures, avoid sudden faults, and improve system reliability. Application scenarios include long-distance driving of vehicles. Through continuous monitoring, early warning can be provided to avoid system failures during driving, which affects driving safety.
[0051] For example, refer to Figures 2 to 4 , the implementation process of the present invention is as follows:
[0052] Reference Figure 2 , the central control screen only receives the display content output by the SOC. The instrument screen can display the display content output by the MCU or SOC, with priority given to the display content output by the MCU. The SOC is installed with the Android system, which supports users to use various applications and supports multi-screen interaction. Both the SOC and the MCU are connected to the gateway in the car to send and receive messages, and can read various data of the vehicle for display on the instrument screen.
[0053] Reference Figure 3, after the vehicle is started, the SOC will automatically start. When the SOC is started, it will continue to generate and output different display contents to the instrument screen and the central control screen. When the SOC successfully outputs the display content to the instrument screen, it will send a message through the gateway. If the SOC fails to output the display content to the instrument screen, a fault message will be sent to prompt the user.
[0054] Reference Figure 4 , after the vehicle is started, the MCU will automatically start. When the MCU is started and does not receive the message sent by the SOC, it will output the display content to the instrument screen. When the MCU receives the message from the SOC, it will stop outputting the display content. When the MCU finds that the SOC message has timed out, it will re-output the display content to the instrument screen to ensure that the instrument screen will not freeze or freeze.
[0055] It should be noted that in addition to the central control screen, the SOC screen can also be connected to more screens to achieve multi-screen interaction, such as the co-pilot screen and the screen on the back seat. The SOC and MCU can communicate in forms other than the gateway, such as directly connecting to the vehicle CAN network, or the two can be directly connected through Ethernet, private CAN, etc.
[0056] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present invention.

Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.
