[0042] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout identify the same or similar originals or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0043] In the field of automotive interaction, the Electronic Control Unit (ECU) is one of the core electronic components of the car, which can connect various sensors and actuators in the vehicle to control the engine, transmission, chassis and other systems. The communication between the various systems is completed through the Controller Area Network (CAN), which is a serial communication protocol used in vehicle electronic control systems and can connect ECUs and sensors in the vehicle.

[0044] The working status of the vehicle can be obtained through various sensors deployed by the ECU on the vehicle body. In related technologies, in order to facilitate the driver to easily view the current main working status of the vehicle, a display screen is set in the center of the steering wheel to display key information of the current working status of the vehicle in a timely manner. Figure 1 Schematic diagram of a steering wheel with a steering wheel display device in the related art. Figure 1 As shown, the steering wheel display device is a display screen that can display a variety of information, such as "vehicle speed", "parking P", "turn angle" and other information. The display screen is set in the center of the steering wheel. When the driver rotates the steering wheel, the steering wheel display device will also rotate with the rotation of the steering wheel.

[0045] In actual scenarios, when the vehicle is driving straight or making a very small turn, the brightness of the steering wheel display device remains constant. When the vehicle is making a large turn, the brightness of the steering wheel display device remains constant. At this time, the driver's attention is on operating the steering wheel, controlling the speed of the vehicle, and observing the conditions outside the vehicle, and he has no time to pay attention to the content on the steering wheel display device. Therefore, the fixed brightness of the steering wheel display device in the related art cannot adapt to the actual driving scenario, and the steering wheel display device has the problem of high power consumption when it is always on with a fixed brightness.

[0046] The present disclosure aims to solve the problem that the brightness of a car steering wheel equipped with a steering wheel display device is fixed and the power consumption is high, so that the brightness of the steering wheel display device can be adjusted according to the rotation angle during the steering wheel rotation process, and the brightness of the steering wheel display device can be dynamically adjusted by sensing the steering wheel rotation angle and using a mapping table of preset rotation angle and display brightness. In this way, the brightness of the steering wheel display device can be flexibly adjusted and the power consumption of the vehicle can be reduced.

[0047] The display control method proposed in the present disclosure is applied to a vehicle whose steering wheel has a steering wheel display function. It can be applied to the automotive field, especially to assisted driving scenarios. The application scenarios are not limited in the embodiments of the present disclosure.

[0048] The display control method provided by the present application is described in detail below with reference to the accompanying drawings.

[0049] Figure 2 : is a flow chart of a display control method according to an embodiment of the present disclosure. The method is executed by a steering wheel display controller of a vehicle, such as Figure 2 In the embodiment shown, the display control method includes:

[0050] Step 201, obtaining a first steering wheel rotation angle of a vehicle, wherein the steering wheel of the vehicle is provided with a steering wheel display device.

[0051] In this embodiment, the vehicle includes a car, a truck, a motorcycle, a bus, etc., preferably a car; the first steering wheel rotation angle is the angle at which the steering wheel rotates when the driver operates the steering wheel of the vehicle, and the steering wheel display device is a display screen arranged in the center of the steering wheel, which is used to display vehicle status information. The first steering wheel rotation angle is the angle at which the steering wheel rotates, and the rotation angle can be collected by a built-in steering wheel angle sensor, or obtained by collecting and analyzing the steering wheel rotation angle through the sensor of the ECU deployed on the whole vehicle.

[0052] Step 202: Based on a first steering wheel rotation angle, determine a first display brightness through a preset angle and brightness mapping table.

[0053] In this embodiment, the first steering wheel rotation angle is determined through step 201, and the angle and brightness mapping table is a correspondence table between the steering wheel rotation angles measured in the laboratory and the brightness of the steering wheel display device that is comfortably acceptable to the eyes. The first display brightness is the brightness value of the steering wheel display device corresponding to the first steering wheel rotation angle determined by searching the preset angle and brightness mapping table for the first steering wheel rotation angle.

[0054] Step 203: Control the display brightness of the steering wheel display device to be a first display brightness.

[0055] In this embodiment, according to the first display brightness determined in step 202, the brightness of the display screen of the steering wheel display device is controlled in the steering wheel display controller to be set to the first display brightness, thereby completing the adjustment of the brightness of the steering wheel display device.

[0056] In summary, according to the display control method proposed in the present disclosure, the first steering wheel rotation angle of the vehicle is obtained, and the steering wheel of the vehicle is provided with a steering wheel display device, and the basis for controlling the brightness of the steering wheel display device is obtained; based on the first steering wheel rotation angle, the first display brightness is determined by a preset angle and brightness mapping table, and a target value is provided for the brightness of the steering wheel display device; the display brightness of the steering wheel display device is controlled to be the first display brightness, and the brightness of the steering wheel display device is adjusted to a brightness value determined according to the angle. The problem of fixed brightness and high power consumption of the steering wheel of a car provided with a steering wheel display device is solved, the flexibility of brightness adjustment of the steering wheel display device is improved, and the power consumption of the vehicle is reduced.

[0057] Figure 3 The present invention is a flowchart of a method for obtaining a first steering wheel rotation angle of a vehicle according to an embodiment of the present invention. Figure 3 Yes Figure 2 Step 201 is further described based on Figure 3 The embodiment shown comprises the following steps:

[0058] Step 301, obtaining a first steering wheel rotation angle collected by a steering wheel angle sensor in a steering wheel system, wherein the steering wheel system includes a steering wheel, a steering wheel angle sensor, a steering wheel display controller and a steering wheel display device.

[0059] In this embodiment, the steering wheel system is a series of devices used to change or maintain the driving or reverse direction of the vehicle, including a steering wheel, an angle sensor, a steering wheel display controller and a steering wheel display device. The angle sensor is a sensor for measuring the steering wheel rotation angle, and the steering wheel display controller is an electronic control system for controlling the steering wheel display device, which can control the display content and direction of the steering wheel display device. The rotation angle of the steering wheel when the driver rotates it can be collected through the angle sensor deployed in the steering wheel system. This rotation angle is the first steering wheel rotation angle.

[0060] In this embodiment, the steering wheel rotation angle is collected inside the steering wheel system as the first steering wheel rotation angle. Due to the variety of sensors deployed on the vehicle body, the first steering wheel rotation angle can also be obtained by relying on external sensors of the steering wheel system.

[0061] Figure 4 The present invention is a flowchart of a method for obtaining a first steering wheel rotation angle of a vehicle according to an embodiment of the present invention. Figure 4 Yes Figure 2 Step 201 is further described based on Figure 4 The embodiment shown comprises the following steps:

[0062] Step 401: receiving a first steering wheel rotation angle sent by an electronic control unit ECU of a vehicle via a controller area network CAN.

[0063] In this embodiment, the electronic control unit ECU includes many kinds of sensors, such as vehicle speed sensor, rotation speed sensor, throttle position sensor, crankshaft position sensor, intake pressure sensor, coolant temperature sensor, etc. Among them, the steering angle sensor, steering torque sensor and steering wheel angle sensor are used to determine the vehicle steering wheel rotation angle. These sensors convert the steering wheel rotation angle and steering torque into electrical signals and output them to the ECU, and the ECU sends these signals to the steering wheel display controller through the controller area network CAN. Therefore, the steering wheel display controller can receive the first steering wheel rotation angle of the vehicle.

[0064] In this embodiment, the first steering wheel rotation angle is collected by components other than the steering wheel system in the vehicle ECU, providing a data basis for the steering wheel controller to adjust the brightness of the steering wheel display device. Similarly, the brightness adjustment of the steering wheel display device can be manually adjusted by the driver.

[0065] Figure 5 The present invention is a flowchart of a display control method according to an embodiment of the present invention. Figure 5 Yes Figure 2 Another description of the embodiment, based on Figure 5 The embodiment shown comprises the following steps:

[0066] Step 501: Acquire a second display brightness, where the second display brightness is a display brightness expected by a user.

[0067] In this embodiment, the second display brightness is the target brightness that the driver thinks the steering wheel display device should be adjusted to. The driver can manually input it into the steering wheel display controller, and the input can be a number or a slide bar. In this embodiment, the input method is not limited.

[0068] Step 502: Update the display brightness of the steering wheel display device to a second display brightness.

[0069] In this embodiment, the brightness value manually set by the driver is used as the second display brightness, and the second display brightness is set as the display brightness value of the current steering wheel display device in the steering wheel display controller, thereby updating the display brightness of the steering wheel display device.

[0070] In this embodiment, for the brightness control of the steering wheel display device, the brightness of the steering wheel display device can be updated by manual adjustment by the driver. This interaction facilitates the user to adjust the brightness. Corresponding to manual brightness adjustment, the steering wheel display device can also adjust the brightness and reduce power consumption by automatically adjusting the brightness.

[0071] Figure 6 The present invention is a flowchart of a display control method according to an embodiment of the present invention. Figure 6 Yes Figure 2 Another description of the embodiment, based on Figure 6 The embodiment shown comprises the following steps:

[0072] Step 601 : receiving a third display brightness determined by an electronic control unit ECU of a vehicle through the vehicle interior ambient light collected by a light sensor deployed in the vehicle and / or the vehicle exterior ambient light collected by a light sensor deployed outside the vehicle.

[0073] The light sensor is a sensor based on the photoelectric effect. When exposed to visible light, it generates a photoelectric effect and converts the light signal into an electrical signal output, which can be used to measure light intensity. The light sensor is deployed only in the in-vehicle part of the vehicle ECU to collect the intensity of the ambient light in the vehicle; the light sensor is deployed only in the outside part of the vehicle ECU to collect the intensity of the ambient light outside the vehicle; or the light sensor is deployed in both the outside and inside parts of the vehicle ECU to collect the ambient light outside the vehicle and the ambient light inside the vehicle. The brightness of the steering wheel display device corresponding to the current ambient light is determined in a linear or nonlinear manner through the collected in-vehicle ambient light and / or the outside ambient light, that is, the third display brightness.

[0074] In one implementation of this embodiment, only the interior / exterior ambient light intensity x is collected, then the third display brightness y of the steering wheel display device can be determined by y=kx+b, where k and b are constants and can be fitted in the test data consisting of (x, y).

[0075] In one implementation of this embodiment, the ambient light inside the car is a, and the ambient light outside the car is b. The third display brightness y of the steering wheel display device can be determined by y=ma+nb+p, where m, n and p are all constants and can be fitted in the test data formed by (a, b, y).

[0076] In one implementation of this embodiment, if only the vehicle interior / exterior ambient light intensity x is collected, the second display brightness y of the steering wheel display device can be determined by a nonlinear function such as y=a*x*x+b*x+c, where a, b, and c are all constants, obtained by fitting in the test data formed by (x, y). The nonlinear function here is only used for illustration and does not limit the functional relationship between the vehicle interior / exterior ambient light intensity x and the third display brightness y of the steering wheel display device.

[0077] Step 602: Update the display brightness of the steering wheel display device to a third display brightness in a first cycle.

[0078] In this embodiment, the first cycle is the inverse of the screen refresh rate of the steering wheel display device. After the third display brightness has been determined, the steering wheel display controller updates the display brightness of the steering wheel display device to the third display brightness with the first cycle.

[0079] In this embodiment, ambient light data is obtained through light sensors deployed inside / outside the vehicle, and the display brightness of the steering wheel display device is obtained based on the ambient light data. Dynamic adjustment of the brightness of the steering wheel display device is achieved, and the display brightness of the steering wheel display device is automatically adjusted according to the brightness of the environment. The flexibility of the brightness adjustment of the steering wheel display device is improved, and the power consumption of the vehicle is reduced compared to a steering wheel display device with a higher brightness and always on. At the same time, during the brightness adjustment process of the steering wheel display device, the display content in the steering wheel display device also needs to be synchronized with the ECU.

[0080] Figure 7 The present invention is a flowchart of a method for synchronizing a steering wheel display device according to an embodiment of the present invention. Figure 7 Yes Figure 2 , Figure 3 and Figure 4 Further description of any embodiment in Figure 7 The embodiment shown comprises the following steps:

[0081] Step 701: synchronize the display brightness and / or display content of the steering wheel display device to the electronic control unit ECU of the vehicle.

[0082] In this embodiment, during the adjustment of the display brightness of the steering wheel display device, the display brightness value is synchronized with the vehicle's ECU; or when the display content of the steering wheel display device changes according to the data collected by the sensor, the display content is synchronized with the vehicle's ECU; or the display brightness and display content of the steering wheel display device are synchronized with the vehicle's ECU at the same time. This allows the vehicle ECU to control changes in vehicle data and facilitates calculation and judgment by the ECU.

[0083] Figure 8FIG. 1 is a flow chart of a brightness control method according to an embodiment of the present disclosure. Figure 8 As shown, in this embodiment, the device starts Startup, and the device represents the steering wheel display system, including a display screen, a six-axis sensor, and a CAN. The vehicle synchronizes brightness information and steering wheel angle information in real time, and provides the steering wheel system with the brightness Brightness of the steering wheel display screen (steering wheel display device) and the steering wheel rotation angle Angle through CAN. According to the continuously updated steering wheel rotation angle Angle, the relative rotation angle ΔAngle is calculated. The brightness Brightness of the steering wheel display screen is determined according to the relative rotation angle ΔAngle. When the relative rotation angle ΔAngle is 0, it means that the current steering wheel has not rotated, and the brightness of the steering wheel display screen remains at the brightness Brightness determined last time; if the relative rotation angle is not 0, it means that the current steering wheel has rotated, and then it is further determined whether the rotation angle is close to 90° or -90°. If it is close to 90° or -90°, the brightness is adjusted to close to 0, that is, the screen display is turned off; if it is not close to 90 or -90°, the brightness of the steering wheel display screen is determined according to the preset mapping table of the steering wheel rotation angle and the brightness of the steering wheel display screen. The brightness Brightness of the steering wheel display screen corresponding to the current steering wheel rotation angle Angle is determined. At the same time, the brightness value of the steering wheel display screen is used as the initial value for the next brightness adjustment. In this embodiment, the brightness of the steering wheel display device is determined by the collected steering wheel rotation angle, and the brightness adjustment of the steering wheel at different rotation angles is realized, which solves the problem of fixed brightness and high power consumption of the steering wheel of the car equipped with the steering wheel display device, improves the brightness adjustment flexibility of the steering wheel display device, and reduces the power consumption of the vehicle.
