[0002] With the development of the motorcycle industry, the level of electrification and intelligence of motorcycles is getting higher and higher. In order to better meet the needs of consumers, existing motorcycles are generally equipped with electronic touch modules for information interaction with the driver, so that the driver can perform operations such as navigation, voice and listening to music while driving the vehicle. In addition, the traditional mechanical switch control function is gradually integrated into the display screen, allowing the driver to control more and more functions through the screen.

[0003] However, motorcycle displays generally have the problems of high power consumption and poor operation convenience. On the one hand, motorcycle displays need to be exposed to sunlight, which requires high screen brightness, so the power consumption is high when the display is always on; on the other hand, it is very inconvenient for the driver to operate the screen during high-speed driving, which will distract the driver's attention and affect driving safety.

[0040] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0041] Embodiment 1

[0042] Please refer to Figure 1-Figure 3 This embodiment discloses a motorcycle display screen control device, including: a detection module 303, a main control unit, a touch module 302 and a central processing module.

[0043] Specifically, the detection module 303 is used to detect in real time whether there is an obstruction within the detection range. If an obstruction is detected within the detection range, a detection signal is sent to the main control unit; the main control unit is used to determine whether the obstruction is a touch gesture based on the detection signal. If so, a control signal is sent to the central processing module; the central processing module is used to control the switching of the display state of the touch module 302 according to the control signal.

[0044] In this embodiment, the motorcycle display screen control device can detect the approach and departure of obstructions in advance by setting a detection module 303 near the touch module 302, and realize prediction and rapid response to touch operations, thereby completing preparations before the operation occurs. This not only avoids the delay problem of traditional touch screens waiting for actual touch to respond, but also realizes intelligent switching of display states, effectively reducing system power consumption while improving operational convenience and smoothness.

[0045] In a specific embodiment, the detection module 303 includes two sensors symmetrically arranged about the central axis of the touch module, and the distance between the detection modules 303 is 1 / 2 of the length of the touch module along the first direction.

[0046] In a specific embodiment, the sensor is a TOF sensor (time of flight sensor). The sensor adopts a TOF distance sensor integrated with an infrared gesture recognition function, and the sensor acquires the spatial position information of the obstruction by emitting infrared light and receiving a reflected signal.

[0047] In another specific embodiment, the sensor includes a signal transmitting end and a signal receiving end. The signal transmitting end transmits a light signal at a frequency of 40-60HZ; the signal receiving end receives the light signal reflected back to the touch module 302 at a frequency of 40-60HZ. The transmitting end continuously transmits the light signal outward at a certain frequency, and the receiving end continuously receives the reflected light signal at the frequency. During the detection process, once an obstruction is detected in the detection plane, the light signal value received by the receiving end will suddenly change.

[0048] In another specific embodiment, the sensor, the main control unit, the touch module 302 and the central processing module are all arranged in the glass cover plate 301; the detection range of the sensor is fan-shaped, the angle of the fan-shaped is 41 degrees, the detection plane is set at 10-20 cm from the bottom of the glass cover plate, and the detection signal emitted by the sensor has a signal coverage area in the detection plane. Such an arrangement and detection method can make the detection range of the detection module 303 cover the entire area directly above the display screen, and no matter whether the driver's finger operates the screen from the left or right, it can be detected by the sensor before touching the screen.

[0049] During actual installation, a screen display module and two TOF sensors are arranged under the glass cover, where the glass cover and the screen display module are fully bonded together with optical glue, and the two TOF sensors are placed by digging holes in the structural parts below the screen display module.

[0050] Furthermore, in this embodiment, the detection module 303 includes a data generating unit, a trajectory data generating unit and a speed data generating unit.

[0051] The data generation unit is used to establish a standardized coordinate system and map the physical coordinates of the obstruction to the display screen coordinate system; the trajectory analysis unit is used to record multiple position coordinates of the obstruction within a certain preset time, and connect the position coordinates to form a motion trajectory; the speed data generation unit is used to calculate the displacement change rate of the obstruction at different time points, and obtain the dynamic changes in the speed size and direction of the obstruction based on the displacement change rate analysis, and the judgment unit, when the movement speed of the obstruction is within the speed threshold range and the movement trajectory meets the characteristics of the touch gesture, the judgment unit determines that the obstruction is a valid touch gesture and outputs the control signal to the central processing module.

[0052] In a specific embodiment, the motion trajectory includes properties such as the motion direction, motion curvature and motion continuity of the obstruction.

[0053] In this embodiment, when the detection module 303 detects that the moving speed of the obstruction is within the preset speed threshold range, it further analyzes whether the motion trajectory of the obstruction conforms to the predefined gesture feature model. When the motion trajectory matches the gesture feature model, it is determined to be a valid touch gesture. This design can effectively filter out false triggers caused by vehicle vibration or other environmental factors and improve the anti-interference ability of the system. It can be understood that the speed threshold can be set according to the specific vehicle speed. When the vehicle speed is high, the upper and lower limits of the speed threshold are increased to reduce the probability of false triggering; when the vehicle speed is low, the upper and lower limits of the speed threshold are lowered to make the operation more sensitive. This dynamic adjustment mechanism can better adapt to the operational requirements under different driving conditions.

[0054] Furthermore, in this embodiment, the touch control module 302 includes a display unit, a touch control unit and a backlight control unit; the display unit is communicatively connected to the central processing module; the touch control unit is communicatively connected to the main control unit; the backlight control unit is communicatively connected to the main control unit; the main control unit is communicatively connected to the detection module 303, forming a complete signal transmission network.

[0055] In a specific embodiment, the main control unit is communicatively connected to the detection module 303 via IIC (Inter-Integrated Circuit, serial communication bus); the main control unit is communicatively connected to the central processing module via SPI (serial peripheral interface) bus; the main control unit is also communicatively connected to the touch control unit via I2C (Inter-Integrated Circuit internal integrated circuit bus), connected to the display unit via DSI (display serial interface) or LVDS (Low-Voltage Differential Signaling), and connected to the backlight control unit via GPIO (general input / output).

[0056] In this embodiment, if the sensor does not detect any obstruction within the preset time, it communicates with the main control module, and the main control module sends a shutdown signal to the backlight control unit through the GPIO port, and the entire display screen enters a low-power sleep mode. In a specific embodiment, the preset time is 5 seconds. This time setting is based on a comprehensive consideration of the operating frequency and energy consumption optimization in actual driving scenarios. When no operation intention is detected within this time, the system will automatically enter a low-power mode to save energy. At the same time, once a new operation intention is detected, the system can wake up quickly to ensure smooth operation.

[0057] In addition, in this embodiment, the central processing module also obtains the display status of the display unit in the vehicle in real time. If the screen is not operated and is not in the navigation state, the screen backlight is turned off and the screen is dormant.

[0058] It can be seen that when no operation intention is detected within the preset time, the system automatically enters low power consumption mode. At the same time, it monitors the display unit status in real time and actively goes into sleep mode when not in navigation and without operation. This not only ensures efficient use of energy, but also can quickly respond to user operations when needed, fully balancing energy-saving needs and operating experience.

[0059] In this embodiment, the specific working process of the motorcycle display screen control device can be: the main control module monitors the signal of the detection module 303 in real time through IIC and processes it. Once it is determined that the driver's touch action is confirmed, the central processing module SOC is notified through the SPI bus. The central processing module will switch the UI style and transmit the large icon UI interface to the display unit through LVDS / DSI for display. After the driver clicks on a specific function icon in the display unit, the screen sends a function instruction to the SOC, and the SOC controls the execution module of the vehicle together with the main control module to respond to the corresponding control function. Once the touch action is withdrawn, the sensor sends a signal to the main control module again. The main control module determines that the signal value detected by the detection module 303 returns to normal, and determines that the driver's operation of the display screen has stopped, and replies to transmit the small icon UI interface to the screen for display, and sends a shutdown signal to the backlight control unit through the GPIO port within 5S, and the entire display screen immediately enters a low-power sleep mode.

[0060] In a specific embodiment, the touch module 302 is a touch display screen.

[0061] Embodiment 2

[0062] Please refer to Figure 4 This embodiment discloses a method for controlling a motorcycle display screen, which adopts the motorcycle display screen control device disclosed in the first embodiment. The technical effects that can be achieved by the motorcycle display screen control device disclosed in the first embodiment can also be achieved by this embodiment, and will not be described in detail here.

[0063] Specifically, the method includes:

[0064] S1. Real-time detection of whether there is an obstruction within the detection range. If an obstruction is detected within the detection range, a detection signal is sent to the main control unit;

[0065] S2. Determine whether the obstruction is a touch gesture according to the detection signal, and if so, send a control signal to the central processing module; and control the switching of the display state of the touch control module according to the control signal.

[0066] Before performing step S1, the state of the display screen of the target vehicle is first obtained. If the display screen has not been operated and is in a non-navigation state, the screen is turned off.

[0067] In a specific embodiment of step S1, when a feature of an obstruction within a plane is detected, a detection signal is generated.

[0068] In step S2, a detection data packet is generated according to the detection signal, and the detection data packet includes coordinate data of the blocking object, movement trajectory data and velocity vector data.

[0069] In a specific embodiment, the step of acquiring the coordinate data of the obstruction includes: after capturing the precise position of the obstruction in three-dimensional space in real time, establishing a standardized coordinate system, and mapping the physical coordinates to the coordinate system of the display screen. The step of analyzing the motion trajectory includes: recording the continuous position change points of the obstruction to form trajectory data, and constructing a trajectory feature vector, including attributes such as direction, curvature, and continuity, and then applying a curve fitting algorithm to smooth the trajectory data. Therefore, the step of acquiring the velocity vector data includes: calculating the displacement change rate of the obstruction at different time points, and analyzing the dynamic changes in the velocity size and direction of the obstruction, and according to the above changes, establishing a velocity threshold model to filter non-operational actions. The execution order of the above judgment steps is not specifically limited here, and those skilled in the art can set it according to actual conditions.

[0070] In a specific embodiment, the upper limit of the speed threshold can be set to 50 cm / s; the lower limit of the speed threshold can be set to 5 cm / s; when the displacement speed is between these two values, it can be determined to meet the characteristics of the touch gesture.

[0071] In another specific embodiment, when the moving speed of the obstruction meets the moving speed characteristics of the touch gesture, it is further determined whether the moving trajectory of the obstruction meets the moving trajectory characteristics of the touch gesture. Taking the left and right sliding gesture recognition as an example, the system is set to collect point data every 20ms, and 10 points are continuously recorded to form a trajectory. When it is detected that the X-axis displacement is greater than 10cm, the Y-axis fluctuation is less than 2cm, and the moving time is within the range of 0.2-1 second, it can be determined as a valid left and right sliding gesture, thereby triggering the corresponding control command of the display screen.

[0072] In step S2, based on the coordinate data of the obstruction, it is confirmed whether the obstruction is in the effective detection area; and based on the movement trajectory data and the velocity vector data, it is determined whether the movement trend of the obstruction object conforms to the touch operation characteristics, and based on the above three characteristics, it is determined whether the obstruction is a touch control gesture of the driver.

[0073] Furthermore, this embodiment further includes step S3. Specifically, step S3 is to control the touch control module 302 to enter a dormant state when the touch control signal that is about to occur or about to be withdrawn is not detected within a preset time. The touch control signal determination method in step S3 is consistent with that in step S2, and the technical effects that can be achieved are also the same, so it will not be repeated here.

[0074] In this embodiment, a complete motorcycle display screen control method is as follows: after the vehicle is started, the TOF sensor arranged directly below the screen continuously emits a light signal. When an obstruction appears, the TOF sensor sends a signal to the main control module of the main control unit; the main control module determines that the screen is about to have a touch command action, wakes up the screen, and notifies the SOC to switch the UI style. The SOC transmits the large icon UI interface to the screen through a signal line for display, so that the driver can easily find the function icon during driving; after the driver clicks on a specific function icon, the screen sends a function instruction to the SOC, and the SOC controls the execution module of the vehicle together with the main control module to respond to the corresponding control function; when the obstruction is withdrawn from top to bottom, the TOF sensor sends a signal to the main control module again; the main control module determines that the driver's finger has left the screen, the screen touch instruction is terminated, and the SOC is notified to switch to the small icon UI interface and transmit it to the screen through the signal line for display; if the TOF sensor does not detect any obstruction within 5S thereafter, the main control module controls the screen to be off, and the display screen enters a low power consumption mode.

[0075] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
