[0018] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0019] The following describes a display control method proposed in an embodiment of the present invention, applied to a vehicle, with reference to the accompanying drawings. The method includes: controlling the display of a preset screen on at least one of the vehicle's central control display screen 2 and the vehicle's instrument panel screen 1, based on steering wheel angle information.

[0020] In the above embodiments, the vehicle's infotainment system monitors the steering wheel angle information in real time and dynamically determines the display terminal for the SR (Signal Time) display accordingly. This enables intelligent switching between the preset screen and the central control display, ensuring uninterrupted SR information transmission even when the steering wheel obscures the screen, significantly improving driving safety and interaction continuity. Optionally, such as... Figure 5 As shown, the steering wheel angle information is detected by a steering wheel angle sensor. The angle sensor first obtains the pulse signal of the steering wheel angle information, converts the pulse signal into a digital signal, encapsulates the digital signal into a CAN data frame, and transmits it to the vehicle's infotainment system via the CAN bus. The vehicle's infotainment system parses the CAN data frame to obtain the steering wheel angle information. The vehicle's infotainment system controls the display position of the preset screen by setting the endpoint of the data stream. When the endpoint of the data stream is the vehicle's instrument panel, the preset screen is displayed on the instrument panel; when the endpoint of the data stream is the vehicle's central control display screen, the preset screen is displayed on the central control display screen. The CAN bus is a serial communication protocol designed to solve the communication problem between electronic control units within a vehicle and is widely used in automotive, industrial automation, and other embedded systems. The CAN bus adopts a multi-master mode, allowing any node in the network to initiate communication when the bus is idle. It uses differential signal transmission to improve anti-interference capability. Its efficient arbitration mechanism enables the CAN bus to quickly respond to high-priority message requests, making it suitable for applications with high real-time requirements. To meet diverse application needs, CAN has several standards, including high-speed CAN (ISO 11898-2) and low-speed CAN (ISO 11898-3). High-speed CAN is suitable for applications requiring fast data transmission, reaching speeds up to 1 Mbps, while low-speed CAN is used for applications requiring high interference immunity, with a maximum speed of 125 kbps. In summary, the CAN bus, with its high reliability, real-time performance, and flexibility, is the preferred solution for transmitting signals between angle sensors and the vehicle's infotainment system. Before transmitting steering wheel angle data using CAN bus communication, the analog signal generated by the angle sensor needs to be converted into a digital signal using an analog-to-digital converter (ADC). This involves converting continuously changing analog voltages into discrete digital values ​​and performing filtering and calibration to improve measurement accuracy. During transmission, the electronic control unit (ECU) encapsulates the digital signal into a CAN data frame, adding identifiers, control fields, and check fields. The encapsulated CAN data frame is then sent to the CAN transceiver, where it is converted into a differential signal and transmitted via the CAN bus.

[0021] Next, on the vehicle's infotainment system, the CAN transceiver receives differential signals from the CAN bus and converts them into digital signals that the processor can handle. When the CAN controller successfully receives a complete and valid data frame, it triggers a hardware interrupt, notifying the processor that new CAN data is available and invoking the CAN driver interrupt service routine. The driver reads, parses, and verifies the data frame from the CAN controller's receive buffer, storing valid data frames in the buffer for the application to access. Finally, the application triggers a read from the buffer via a callback function to obtain the steering wheel angle value. Furthermore, based on the steering wheel angle information, the vehicle's infotainment system determines the preset screen to be displayed on the instrument cluster screen and / or the central control display screen. Optionally, the steering wheel angle information is used to determine whether the steering wheel obstructs the instrument cluster screen. Based on the obstruction status of the instrument cluster screen, the system controls the display of the preset screen on the instrument cluster screen and / or the central control display screen, ensuring that the driver can see the preset screen regardless of the steering wheel's angle and can continuously obtain information from the preset screen on both the instrument cluster and the central control display screen, thereby improving driving safety and the driving experience.

[0022] Angle sensors are categorized into optical encoder-based angle sensors and magnet-based angle sensors. Optionally, an optical encoder-based angle sensor rotates a hollow disk with slots when the steering wheel is turned. The photosensitive element generates high and low voltage levels due to the slots, and the steering wheel angle can be calculated by combining the number of electrical signals with the size of the optical encoder. Alternatively, a magnet-based angle sensor rotates magnetic poles on the disk when the steering wheel is turned, and the steering wheel angle can also be calculated by counting the number of Hall voltage polarity reversals. Both types of steering wheel angle sensors offer very high accuracy.

[0023] In some embodiments, the preset screen includes a real-time display of the vehicle's environment.

[0024] In the above embodiments, the Reality Scene (SR) image is generated by the vehicle-mounted perception system by fusing data from cameras, millimeter-wave radar, and ultrasonic sensors. It renders information such as 360° surrounding traffic participants, lane lines, traffic signs, and obstacles in real time to enhance the driver's perception of complex environments. The SR image maintains rendering consistency during switching and does not reset its rendering state due to changes in the display terminal, ensuring image continuity.

[0025] In some embodiments, the steering wheel angle information includes a steering wheel angle value. Controlling the display of a preset screen on at least one of the vehicle's central control display screen and the vehicle's instrument panel screen based on the steering wheel angle information includes: determining a preset angle range in which the steering wheel angle value is located; and controlling the display of a preset screen on at least one of the vehicle's central control display screen and the vehicle's instrument panel screen based on the preset angle range in which the steering wheel angle value is located.

[0026] In the above embodiment, the steering wheel angle is the angle by which the steering wheel 3 rotates relative to its position when the vehicle is traveling straight. For example... Figure 1 The image shows the position of the steering wheel when the vehicle is traveling straight, with a steering wheel angle of 0°. An angle sensor is integrated into the steering wheel. This sensor detects the steering wheel angle in real-time at regular time intervals and transmits the angle value to the vehicle's infotainment system via the CAN bus. The system then determines the preset angle range of the steering wheel and the display position of a preset screen based on this determination. This real-time detection method allows the angle sensor to send steering wheel angle information to the CAN bus at extremely short intervals. This real-time detection and transmission method enables the vehicle's infotainment system to obtain the steering wheel angle value at every moment and make timely decisions based on this value. The logical decision-making is entirely handled by the infotainment system; the angle sensor only collects the steering wheel angle value and sends data to the system, without participating in the decision-making process. This method decouples the angle sensor's functional module from the infotainment system's logic module, reducing module coupling. Furthermore, other functions that rely on the angle sensor, such as automatic steering wheel return and power steering, also require the infotainment system to obtain the steering wheel angle detected by the sensor at every moment. Therefore, this method unifies requirements and reduces the bloat and redundancy of functional modules caused by customized features.

[0027] In some embodiments, the steering wheel angle information includes a preset angle range in which the steering wheel angle value is located. Controlling the display of a preset screen on at least one of the vehicle's central control display screen and the vehicle's instrument panel screen based on the steering wheel angle information includes: controlling the display of a preset screen on at least one of the vehicle's central control display screen and the vehicle's instrument panel screen based on the preset angle range in which the steering wheel angle value is located.

[0028] In the above embodiment, the angle sensor detects the steering wheel angle value in real time and determines the preset angle range of the steering wheel angle value. The sensor then sends the determination result to the vehicle's infotainment system via the CAN bus. The infotainment system determines the display position of the preset screen based on the determination result; this is a trigger-based method. The trigger-based method implements some of the logic processing by the electronic control unit of the angle sensor, and the vehicle's infotainment system only controls the display position of the preset screen based on the angle sensor's determination result. This method reduces the information transmission frequency, thus reducing the CAN bus occupancy time and lowering the vehicle's infotainment system performance consumption. Optionally, the angle sensor's determination result can be sent to the vehicle's infotainment system as the steering wheel angle value. For example, when the steering wheel angle value detected by the angle sensor changes from one preset angle range to another, the angle sensor sends the detected changed steering wheel angle value to the vehicle's infotainment system. The vehicle's infotainment system then executes the target transmission position of the preset screen data stream, enabling the preset screen to be displayed at the target position. Optionally, an electronic control unit (ECU) is pre-installed within the angle sensor. The ECU determines the desired display position of the preset screen based on the steering wheel angle value detected by the angle sensor, converts it into a digital signal, and sends it to the vehicle's infotainment system via the CAN bus. The vehicle's infotainment system can directly control the display position of the preset screen based on the received data without further logical judgment. Optionally, the preset angle range can be calibrated during system initialization. For example, before the vehicle leaves the factory, real-vehicle testing can determine the starting and ending steering wheel angles for obscuring the instrument panel. This range of steering wheel angle information is then fixed as system parameters. The vehicle's infotainment system directly reads this range and executes the switch, eliminating the need for real-time angle calculation and reducing computational load.

[0029] In some embodiments, the preset turning angle range includes a first preset turning angle range. Based on the preset turning angle range in which the steering wheel turning angle value is located, controlling the preset screen to be displayed on at least one of the vehicle central control display screen and the vehicle instrument panel screen includes: when the steering wheel turning angle value is within the first preset turning angle range, controlling the preset screen to be displayed on at least the vehicle central control display screen, wherein when the steering wheel turning angle value is within the first preset turning angle range, the steering wheel obscures at least a portion of the vehicle instrument panel screen.

[0030] In the above embodiments, the steering wheel obstructs at least a portion of the vehicle's instrument panel, indicating that during normal driving, when the driver is in a normal driving posture (i.e., without leaning forward, sideways, or backward), the steering wheel obstructs some of the light transmitted to the driver from the instrument panel, thus preventing the driver from observing the entire preset screen displayed on the instrument panel. The first preset steering angle range can be preset before the vehicle leaves the factory or adjusted by the user during vehicle use. When the steering wheel angle value is within the first preset angle range, the steering wheel obstructs at least a portion of the instrument panel, preventing the driver from seeing the complete information displayed on the instrument panel, increasing driving risk. In this case, the vehicle's central control display screen needs to display the preset screen so that the driver can fully observe the vehicle's relevant information through the central control display screen. Optionally, when the steering wheel angle value is within the first preset angle range, only the central control display screen displays the preset screen. Optionally, when the steering wheel angle value is within the first preset angle range, both the instrument panel and the central control display screen jointly display the preset screen. In some embodiments, the preset turning angle range includes a second preset turning angle range. Based on the preset turning angle range in which the steering wheel turning angle value is located, the preset screen is controlled to be displayed on at least one of the vehicle's central control display screen and the vehicle's instrument panel screen. This includes: when the steering wheel turning angle value is within the second preset turning angle range, the preset screen is controlled to be displayed on at least the vehicle's instrument panel screen, wherein when the steering wheel turning angle value is within the second preset turning angle range, the steering wheel does not obstruct the vehicle's instrument panel screen.

[0031] In the above embodiments, the second preset steering angle range can be calculated from the first preset steering angle range. When the steering wheel angle value is within the second preset steering angle range, the steering wheel does not obstruct the instrument panel, therefore at least the instrument panel displays the preset image. Compared to displaying the preset image on the central control display screen, displaying the preset image on the instrument panel makes it easier for the driver to see and improves driving safety. Optionally, when the steering wheel angle value is within the second preset steering angle range, only the instrument panel displays the preset image. Optionally, when the steering wheel angle value is within the second preset steering angle range, the preset image is jointly displayed on both the instrument panel and the central control display screen.

[0032] Optionally, in some processes, the steering wheel angle rapidly passes through a second preset angle range within a first preset angle range and then switches back to the first preset angle range. In this case, it's possible that when the steering wheel angle switches from the first preset angle range to the second preset angle range, the vehicle's infotainment system does not promptly switch the preset display from the instrument cluster screen to the central control screen. Then, when the steering wheel angle switches back from the second preset angle range to the first preset angle range, the infotainment system does not switch the display position. Optionally, in other processes, the steering wheel angle rapidly passes through a second preset angle range within a first preset angle range and then switches back to the first preset angle range. In this case, it's possible that when the steering wheel angle switches from the first preset angle range to the second preset angle range, the infotainment system promptly switches the preset display from the central control screen to the instrument cluster screen. Then, when the steering wheel angle switches back from the second preset angle range to the first preset angle range, the infotainment system needs to switch the display position again, i.e., switch the display position from the instrument cluster screen to the central control screen.

[0033] In some embodiments, the steering wheel angle value is detected by an angle sensor. When the steering wheel angle value is within a first preset angle range, the preset screen is controlled to be displayed at least on the vehicle's central control display screen, including: when the steering wheel angle value is within the first preset angle range, the display data stream is controlled to flow at least to the vehicle's central control display screen.

[0034] In the above embodiments, the data stream is the data information of a preset screen. Optionally, when the steering wheel angle is within a first preset angle range, the vehicle system only transmits the data stream of the preset screen to the central control display screen, that is, only the central control display screen displays the preset screen, while cutting off the data stream of the preset screen transmitted to the instrument panel, and the instrument panel does not display the preset screen. Figure 6 As shown. Optionally, when the steering wheel angle value is within the first preset angle range, the vehicle system will simultaneously transmit the data stream of the preset screen to the central control display and the instrument panel, so that the instrument panel and the central control display will display the preset screen at the same time.

[0035] In some embodiments, when the steering wheel angle value is within a second preset angle range, controlling the preset screen to be displayed at least on the vehicle instrument panel includes: when the steering wheel angle value is within the second preset angle range, controlling the display data stream to flow at least to the vehicle instrument panel.

[0036] Specifically, when the steering wheel angle is within the second preset angle range, the steering wheel does not obstruct the instrument panel, meaning the driver can see the complete content of the preset screen displayed on the instrument panel in a normal seating position. Therefore, the data stream controlling the preset screen must at least pass through the vehicle's instrument panel to ensure the preset screen is displayed, facilitating driver viewing and improving driving safety. Optionally, when the steering wheel angle is within the second preset angle range, the vehicle's system only transmits the preset screen data stream to the instrument panel, meaning only the instrument panel displays the preset screen, while cutting off the data stream transmitting the preset screen to the central control display. Figure 7 As shown. Optionally, when the steering wheel angle value is within the second preset angle range, the vehicle system will simultaneously transmit the data stream of the preset screen to the central control display and the instrument panel, so that the instrument panel and the central control display will display the preset screen at the same time.

[0037] In some embodiments, when the steering wheel angle value is within a first preset angle range, controlling the preset screen to be displayed at least on the vehicle's central control display screen includes: when the steering wheel angle value is within the first preset angle range, controlling the vehicle's instrument panel to stop displaying the preset screen.

[0038] In the above embodiments, when the steering wheel angle is within the first preset angle range, the steering wheel at least partially obstructs the instrument panel, and the preset control screen is displayed only on the vehicle's central control display screen. Optionally, when the vehicle system determines that the steering wheel angle has switched from the second preset angle range to the first preset angle range, the steering wheel switches from an unobstructed state to an obstructed state on the instrument panel. At this time, the vehicle system switches the display of the preset screen from the instrument panel to the central control display screen, meaning the instrument panel stops displaying the preset screen, allowing the driver to observe the preset screen only on the central control display screen. This setting allows the vehicle system to switch the display position of the preset screen according to the preset angle range of the steering wheel angle, preventing the central control display screen and the instrument panel from displaying the same image simultaneously. Therefore, the instrument panel can be used to display other images as a supplement to the preset screen, or to display other images that do not affect driving safety to assist driving. It also avoids resource waste and visual interference. Optionally, when the preset display position of the screen is switched from the vehicle's instrument panel to the central control display, the vehicle's infotainment system first shuts down the data flow to the vehicle's instrument panel. Then, the system reopens the data flow and sets the endpoint of the data flow to the central control display, thus completing the switch of the display position.

[0039] In some embodiments, when the steering wheel angle value is within a second preset angle range, controlling the preset screen to be displayed at least on the vehicle instrument panel includes: when the steering wheel angle value is within the second preset angle range, controlling the vehicle central control display to stop displaying the preset screen.

[0040] In the above embodiments, when the steering wheel angle is within the second preset angle range, the steering wheel does not obstruct the instrument panel, and the preset control screen is only displayed on the instrument panel. Optionally, when the vehicle system determines that the steering wheel angle has switched from the first preset angle range to the second preset angle range, the vehicle system switches the display of the preset screen from the central control display to the instrument panel, that is, the central control display stops displaying the preset screen, so that the central control display and the instrument panel will not display the same screen at the same time, avoiding resource waste and visual interference. The central control display can be used to display other screens that do not affect driving safety. Optionally, when the display position of the preset screen switches from the central control display to the instrument panel, the vehicle system first closes the data stream flowing to the vehicle's central control display, and then reopens the data stream and sets the endpoint of the data stream to the instrument panel, completing the switch of the display position. In some embodiments, when the steering wheel angle value meets the following conditions, it is determined that the steering wheel angle is within a first preset angle range: a≤|x|≤b; when the steering wheel angle value meets the following conditions, it is determined that the steering wheel angle is within a second preset angle range: a<|x|≤360° or 0≤|x|<b; where |x| is the absolute value of the steering wheel angle, and a and b are obtained according to user settings or according to vehicle factory presets.

[0041] Specifically, when the steering wheel angle is positive, 'a' is the critical value for the steering wheel angle from an unobstructed state to an obstructed state, and 'b' is the critical value for the steering wheel angle from an obstructed state to an unobstructed state. When the steering wheel angle is negative, '-a' is the critical value for the steering wheel angle from an unobstructed state to an obstructed state, and '-b' is the critical value for the steering wheel angle from an obstructed state to an unobstructed state. The first preset angle range is defined as the steering wheel angle interval [–b, –a] ∪ [a, b], where a and b are the pre-calibrated starting and ending steering wheel angles when the steering wheel obstructs the instrument panel. Optionally, the steering wheel angle is set to positive when rotating clockwise and negative when rotating counterclockwise. The second preset angle range is the steering wheel angle when the steering wheel does not obstruct the instrument panel, at which point the instrument panel is fully visible. For example, if a = 30° and b = 120°, when |x| ∈ [30°, 120°], the system determines it to be in an obstructed state and triggers a switch to the central control display screen; when |x| < 30° or |x| > 120°, it is determined to be in an unobstructed state, and the preset screen returns to the instrument panel. Optionally, since different vehicles have different instrument panel sizes, display ranges, and seat heights, a and b can be adjusted according to different vehicle models. Optionally, since different drivers have different body types, a and b can be adjusted by the driver via the vehicle's infotainment system or a mobile app.

[0042] Optionally, the values ​​of a and b can be recorded by simulating the driver's perspective when sitting in the driver's seat in a normal posture, and by rotating the steering wheel (i.e., changing the steering wheel angle) to record the instrument panel's obstruction state. The recorded values ​​are then input into the corresponding control module of the vehicle's infotainment system. For example... Figure 2 As shown, the steering wheel angle at this time is 'a', as... Figure 3 As shown, at this time the steering wheel angle is greater than a and less than b, as... Figure 4 As shown, the steering wheel angle is equal to b at this time.

[0043] In some embodiments, the steering wheel angle is determined to be within a first preset angle range when the steering wheel angle value meets the following conditions: a+360°≤|x|≤b+360°; the steering wheel angle is determined to be within a second preset angle range when the steering wheel angle value meets the following conditions: a+360°<|x|≤720° or 0≤|x|<b+360°; where |x| is the absolute value of the steering wheel angle, and a and b are obtained according to user settings or vehicle factory presets.

[0044] In the above embodiments, since the steering wheel rotation angle of some vehicle models can exceed 360°, the critical value of the preset angle range is greater than 360°. Optionally, if a=30° and b=120°, the first angle range is defined as 390°≤|x|≤480°, and the second angle range is defined as: 390°<|x|≤720° or 0≤|x|<480°. This application also provides a display device, including a processor and a memory, wherein the memory is used to store executable instructions, and the processor is configured to execute the executable instructions to implement the display control method as described above.
