[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the drawings in the present application only serve the purpose of illustration and description and are not used to limit the scope of protection of the present application.

[0045] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0046] The following methods, devices, electronic devices or computer-readable storage media of the embodiments of the present application can be applied to any scenario requiring display of vehicle compass information. The embodiments of the present application are not limited to specific application scenarios. Any scheme using the method and device for displaying vehicle compass information provided by the embodiments of the present application is within the scope of protection of this application.

[0047] It's worth noting that with the rapid development of intelligent connected vehicles, the electronic compass, as a key functional module, typically collects its core data, heading angle, via a TBOX (onboard telematics terminal) or IMU (inertial measurement unit), which is then transmitted via a bus to the instrument cluster and in-vehicle infotainment system for visual display. However, differences in the data processing logic between the instrument cluster and the in-vehicle infotainment system can lead to inconsistencies between the instrument cluster display and the in-vehicle infotainment system, impacting the user experience.

[0048] In response to the above problems, the embodiments of the present application propose a method and device for displaying vehicle compass information, which realize unified processing and distribution of compass data, ensure real-time synchronization of compass information, and improve the reliability of compass information.

[0049] To facilitate understanding of the present application, the technical solutions provided in the present application are described in detail below in conjunction with specific embodiments.

[0050] See also Figure 1 , Figure 1 This is one of the flow charts of a method for displaying vehicle compass information provided in an embodiment of the present application.

[0051] In this embodiment of the present application, the vehicle compass information display function is activated when the vehicle power is in Local On or Ready mode. In Local On mode, the low-voltage system provides power, while the high-voltage system remains disconnected, rendering the vehicle inoperable. The low-voltage system includes components such as the instrument panel, windows, and audio, while the high-voltage system includes components such as the drive motor, power battery, and electric compressor. In Ready mode, the high-voltage system is powered on, and the vehicle becomes drivable.

[0052] Differences in the compass data processing logic between the instrument cluster and the in-vehicle infotainment system can lead to discrepancies between the instrument cluster display and the in-vehicle infotainment system's display. For example, if the compass information is unreliable and the heading angle is too large, the in-vehicle infotainment system will deem the heading angle invalid. The in-vehicle infotainment display will show the last valid angle, while the instrument cluster will display "--." This embodiment of the application takes into account the impact of vehicle speed on the heading angle. Specifically, low vehicle speed affects the heading angle.

[0053] like Figure 1 As shown in , the method for displaying vehicle compass information provided in the embodiment of the present application is applied to a controller. In the embodiment of the present application, as an example, the controller can be a microcontroller unit (MCU) or other controllers, which are not limited here.

[0054] In an embodiment of the present application, the display method includes the following steps:

[0055] Step S101: Obtain the validity flag, vehicle speed, and heading angle corresponding to the vehicle speed.

[0056] Here, the validity flag is used to determine whether the acquired vehicle speed is valid. Figure 2 As shown in , the electronic stability control system (ESC) sends the validity flag (ESC_VehicleSpeed_Valid) corresponding to the vehicle speed and the vehicle speed to the cockpit domain controller (CCU) via the bus. The on-board telecommunications terminal (TBOX) sends the vehicle heading angle to the cockpit domain controller via the bus. The cockpit domain controller sends the received validity flag corresponding to the vehicle speed, the vehicle speed, and the vehicle heading angle to the microcontroller included in the intelligent domain controller (IDCU) via the bus. In this embodiment of the application, the original vehicle speed (ESC_VehicleSpeed) obtained by the electronic stability control system is in m / s. The microcontroller converts the original vehicle speed into km / h, that is, ESC_VehicleSpeed×3.6 can convert the original vehicle speed in m / s into km / h. The validity flag corresponding to the vehicle speed indicates whether the vehicle speed sent by the cockpit domain controller received by the microcontroller is valid. Specifically, it is valid when the validity flag corresponding to the vehicle speed is equal to 1, that is, when ESC_VehicleSpeed_Valid=0x1, the vehicle speed sent by the cockpit domain controller received by the microcontroller is valid and has no faults; it is invalid when the validity flag corresponding to the vehicle speed is 0, that is, when ESC_VehicleSpeed_Valid=0x0, the vehicle speed sent by the cockpit domain controller received by the microcontroller is invalid or unreliable.

[0057] Step S102: generating a display strategy for vehicle compass information based on the validity flag, the vehicle speed and / or the heading angle.

[0058] Step S103: Based on the display strategy, the corresponding vehicle compass information is simultaneously displayed on multiple vehicle display modules, wherein the vehicle display modules include: a combination instrument panel and an in-vehicle infotainment display screen.

[0059] See also Figure 3 , Figure 3 This is the second flowchart of a method for displaying vehicle compass information provided in an embodiment of the present application.

[0060] like Figure 3 As shown in FIG, regarding step S102, in a specific implementation, as an example, the following steps may be included:

[0061] Step S1021: Determine whether the vehicle speed indicated by the validity flag is valid.

[0062] Step S1022: If the validity flag indicates that the vehicle speed signal is invalid, the display strategy of the generated vehicle compass information is to display the last valid angle; wherein the last valid angle is the last displayed heading angle.

[0063] According to the above generated results, regarding step S103 as an example, Figure 2 As shown in , when the microcontroller unit determines that the validity flag indicates that the vehicle speed signal is invalid, the vehicle compass information is the last valid angle, and the microcontroller unit sends the last valid angle to the vehicle computer underlying system (QNX system) and the vehicle computer upper system (Android system) included in the intelligent domain controller (IDCU). The vehicle computer underlying system displays the last valid angle on the instrument cluster, and the vehicle computer upper system displays the last valid angle on the vehicle infotainment display.

[0064] Step S1023: If the validity flag indicates that the vehicle speed signal is valid, a display strategy for the vehicle compass information is generated based on the vehicle speed and the heading angle.

[0065] Regarding step S1023, in specific implementation, as an example, the following steps may be included:

[0066] Step S10231, determining whether the vehicle speed is less than a preset vehicle speed threshold.

[0067] Step S10232: If the vehicle speed is less than the preset vehicle speed threshold, the display strategy of the generated vehicle compass information is to display the last valid angle.

[0068] In the embodiment of the present application, as an example, the preset speed threshold is 3 km / h. The preset speed threshold can also be set according to actual working conditions or other experience, and is not limited here. A speed less than the preset speed threshold indicates that the vehicle is running at a low speed.

[0069] According to the above-mentioned generation results, regarding step S103 as an example, when the micro-control unit determines that the validity flag indicates that the vehicle speed signal is valid and the vehicle speed is less than the preset vehicle speed threshold, the vehicle compass information is the last valid angle, and the micro-control unit sends the last valid angle to the vehicle computer underlying system and the vehicle computer upper system. The vehicle computer underlying system displays the last valid angle on the instrument cluster, and the vehicle computer upper system displays the last valid angle on the vehicle infotainment display screen.

[0070] Step S10233: If the vehicle speed is not less than the preset vehicle speed threshold, a display strategy for the vehicle compass information is generated based on the heading angle.

[0071] Here, the vehicle speed being not less than the preset vehicle speed threshold indicates that the vehicle is running at a normal speed.

[0072] Regarding step S10233, in a specific implementation, as an example, the following steps may be included:

[0073] Step S102331, determine whether the heading angle is within a preset angle range.

[0074] Here, as an example, the preset angle range is 0-359.9°, with an accuracy of 0.1°, and 0° is defined as the north direction. The preset angle range can also be set according to actual working conditions or other experience, and is not limited here.

[0075] Step S102332: If the heading angle is within a preset angle range, the display strategy of the generated vehicle compass information is to display the heading angle.

[0076] According to the above-mentioned generated results, regarding step S103 as an example, when the micro-control unit determines that the vehicle speed is not less than the preset speed threshold, the validity flag indicates that the vehicle speed signal is valid and the current heading angle is within the preset angle range, the vehicle compass information is the current heading angle, and the micro-control unit sends the current heading angle to the vehicle computer bottom-level system and the vehicle computer upper-level system. The vehicle computer bottom-level system displays the current heading angle on the instrument cluster, and the vehicle computer upper-level system displays the current heading angle on the vehicle infotainment display screen.

[0077] Step S102333: If the heading angle is not within the preset angle range, the display strategy of the generated vehicle compass information is to display a preset invalid value.

[0078] Here, if the heading angle is not within the preset angle range, it indicates that the heading angle sensor may be faulty. As an example, the preset invalid value is set to "--", wherein the preset invalid value can also be set to other representations, which are not limited here.

[0079] According to the above-mentioned generation results, regarding step S103 as an example, when the micro-control unit determines that the vehicle speed is not less than the preset vehicle speed threshold, the validity flag indicates that the vehicle speed signal is valid and the current heading angle is not within the preset angle range, the vehicle compass information is a preset invalid value, and the micro-control unit sends the preset invalid value to the vehicle computer bottom-level system and the vehicle computer upper-level system. The vehicle computer bottom-level system displays the preset invalid value "--" on the instrument cluster, and the vehicle computer upper-level system displays the preset invalid value "--" on the vehicle infotainment display screen.

[0080] In another embodiment provided by the present application, the display method further includes:

[0081] If the validity flag is not obtained within the first preset time and / or the vehicle speed is not obtained within the first preset time, the display strategy of the generated vehicle compass information is to display a preset invalid value; if the vehicle speed is obtained within the first preset time, the validity flag is obtained within the first preset time and the heading angle is not obtained within the second preset time, the display strategy of the generated vehicle compass information is to display a preset invalid value; wherein, the first preset time is less than the second preset time.

[0082] Here, if the validity flag is not obtained within the first preset time, the vehicle speed is not obtained within the first preset time, and the heading angle is not obtained within the second preset time, it indicates that the signal has been lost. As an example, the first preset time is 500ms and the second preset time is 250ms. The first preset time and the second preset time can also be set according to actual operating conditions or other experience and are not limited here.

[0083] Based on the above generation results, regarding step S103 as an example, if the microcontroller fails to obtain the validity flag corresponding to the vehicle speed and / or the vehicle speed for 500 ms, or fails to obtain the heading angle for 250 ms, the vehicle compass information is a preset invalid value. The microcontroller sends the preset invalid value to the vehicle computer bottom system and the vehicle computer upper system. The vehicle computer bottom system displays the preset invalid value "--" on the instrument cluster, and the vehicle computer upper system displays the preset invalid value "--" on the in-vehicle infotainment display screen until data is retrieved, and the process returns to step S102. If the microcontroller obtains the vehicle speed and the validity flag corresponding to the vehicle speed for 500 ms, and fails to obtain the heading angle for 250 ms, the microcontroller sends the preset invalid value to the vehicle computer bottom system and the vehicle computer upper system. The vehicle computer bottom system displays the preset invalid value "--" on the instrument cluster, and the vehicle computer upper system displays the preset invalid value "--" on the in-vehicle infotainment display screen until data is retrieved, and the process returns to step S102.

[0084] This application solves the problem of inconsistent vehicle compass information display when the vehicle speed is too low, the vehicle compass information is unreliable, and the signal is lost.
