[0059] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0060] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0061] Existing types of automotive steering wheel switches can be accidentally activated, leading to driver malfunctions. To address this problem, some embodiments of this application collect the target trajectory input by the user on the touchscreen of the vehicle's steering wheel switch; identify whether the target trajectory corresponds to a target character; if the target trajectory corresponds to a target character, generate a control command for the functional device corresponding to the target character to execute the function of the functional device. The user first inputs the target trajectory via the touchscreen, and after the target trajectory is identified as a target character, the corresponding functional device is executed, reducing driver malfunctions.

[0062] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0063] Figure 1 This is a flowchart illustrating a vehicle steering wheel switch control method provided as an exemplary embodiment of this application. Figure 1 As shown, the method includes:

[0064] S101: Collects the target trajectory input by the user on the touchscreen on the vehicle's steering wheel;

[0065] S102: Identify whether the target trajectory has a corresponding target character; if the target trajectory has a corresponding target character, proceed to step S103; if the target trajectory does not have a corresponding target character, proceed to step S104.

[0066] S103: Generate control instructions for the functional device corresponding to the target character, so as to execute the function of the functional device corresponding to the target character;

[0067] S104: Send a target trajectory unrecognizable instruction to the display device so that the display device can display unrecognizable characters.

[0068] In this embodiment, the execution subject of the above method is an in-vehicle device installed on the vehicle, such as one or more of a steering wheel switch controller, a vehicle controller, and a smart cockpit domain controller. This application does not limit the above embodiment; it can also be a personal computer, tablet computer, smart speaker, or smart wearable device, etc.

[0069] In this embodiment, a touchscreen is provided on each side of the vehicle steering wheel, and the user operates the touchscreens on both sides using their left and right hands respectively. This application does not limit the number of touchscreens; the number can be single or multiple. Furthermore, this application does not limit the location of the touchscreens; they can be located in the center of the vehicle steering wheel.

[0070] In this embodiment, it is necessary to pre-set the correspondence between characters and the functions of functional devices. One possible approach is to set the correspondence between characters and the functions of functional devices in response to a function setting operation. Optionally, a function setting interface is displayed on a display device, the function setting interface including at least one function; in response to a selection operation of the at least one function, the selected function is designated as a first function; in response to a handwriting input of a first character on a touchscreen, a correspondence between the first character and the first function is established. The display device can be a central control screen or a head-up display. It should be noted that the user in this embodiment can be a driver, passenger, or other user.

[0071] For example, to prevent accidental triggering of function settings by the user, each function setting operation requires a long press on either of the touchscreens on either side of the steering wheel. The steering wheel switch controller detects this long press and sends a vibration command to the touchscreen, which vibrates to alert the user. The central control screen displays a function setting confirmation control. Responding to the user's triggering of this control, the central control screen displays the function setting interface. The left side of the central control screen is a selection area, displaying at least one function. The steering wheel switch controller responds to the user's selection of at least one function, designating the selected function as the first function. The steering wheel switch controller also responds to the user's handwriting input of the first character on the touchscreen. After inputting the first character, the user long presses either of the touchscreens on either side of the steering wheel. The steering wheel switch controller detects this long press and sends a vibration command to the touchscreen, which vibrates to alert the user. Simultaneously, the first function moves to the right side of the central control screen, completing the function setting operation for that function. The process continues for each subsequent function until all functions are set. The central control screen also includes a preset end control. The steering wheel switch controller responds to the user's triggering of this control, closing the function setting operation.

[0072] In this embodiment, after the user presets the correspondence between characters and the functions of functional devices, the correspondence between characters and functional devices can also be canceled. One possible implementation is that the steering wheel switch controller responds to a function cancellation operation and cancels the correspondence between characters and the functions of functional devices. Optionally, a function cancellation interface is displayed on the display device, the function cancellation interface including at least one function with an established correspondence; in response to a selection operation of the at least one function with an established correspondence, the selected function is designated as a second function; the steering wheel switch controller responds to an operation of handwriting input on the touch screen to input a second character corresponding to the second function, thereby releasing the correspondence between the second function and the second character.

[0073] For example, before the function setting operation is completed, if the user clicks on an established function on the right side of the central control screen, the steering wheel switch controller responds to the user's selection of at least one established function, designating the selected function as the second function. The steering wheel switch controller then responds to the user's handwriting input of the second character corresponding to the second function on the touchscreen. After the user inputs the second character, the user presses and holds either touchscreen on either side of the steering wheel. The steering wheel switch controller detects this press and sends a vibration command to the touchscreen, causing it to vibrate to alert the user. Simultaneously, the second function is moved to the left-hand selection area. After the function setting operation is completed, if the user presses and holds the touchscreen again, the steering wheel switch controller detects this press and sends a vibration command to the touchscreen, causing it to vibrate to alert the user. Similarly, if the user selects at least one established function, the steering wheel switch controller designates the selected function as the third function. The steering wheel switch controller responds to the user's handwriting input of the third character corresponding to the third function on the touchscreen. After the user inputs the third character, the user presses and holds either touchscreen on either side of the steering wheel. The steering wheel switch controller detects this press and sends a vibration command to the touchscreen, causing it to vibrate to alert the user. Simultaneously, the third function is moved to the left-hand selection area.

[0074] Optionally, numeric characters correspond to driving-related functions (e.g., vehicle acceleration, deceleration, cruise control, and autonomous driving), while alphanumeric characters correspond to entertainment or other non-driving-related functions (volume up, volume down, previous track, next track, mute, and voice). The target characters in this application include, but are not limited to: numbers 0-9, and letters from the alphabet AZ excluding I / L / O / Q / T / U / Z. Combinations of numbers, letters, or a combination of letters and numbers are not supported to improve recognition accuracy.

[0075] In this embodiment, the vehicle steering wheel switch control device monitors the user's activation operation on the touchscreen on the vehicle steering wheel and sends an activation command to the touchscreen to activate it, for example, activating the touchscreen from a sleep state or a power-off state. After the user handwrites the target trajectory on the touchscreen, the vehicle steering wheel switch control device collects the handwritten target trajectory on the touchscreen on the vehicle steering wheel and identifies whether the target trajectory is a preset target character. One possible approach is to calculate the similarity between the target trajectory and multiple preset characters one by one, and select the preset character with the highest similarity as the target character.

[0076] In the above embodiments, the user's activation operation on the touch screen on the vehicle steering wheel includes any one of the following: long press, double tap, and double tap.

[0077] In the above embodiment, after the vehicle steering wheel switch control device issues an activation command to the touchscreen to activate it, it sends a prompt command to the touchscreen to perform an activation prompt action. The activation prompt action includes at least one of the following: vibration, screen brightness change, and playing a prompt voice. The screen brightness change includes switching the screen from black to light, increasing the screen brightness, and decreasing the screen brightness. Playing a prompt voice, such as "Touchscreen has been activated," is also included.

[0078] One embodiment of touchscreen activation is that, in response to a user's long press operation on the touchscreen on the vehicle's steering wheel, the vehicle steering wheel switch control device causes the touchscreen to vibrate to indicate to the user that the touchscreen has been activated.

[0079] In the above embodiments, after recognizing the target trajectory as a preset target character, the vehicle steering wheel switch control device generates a control command for the functional device corresponding to the target character to execute the function of the functional device corresponding to the target character; if the vehicle steering wheel switch control device does not recognize the target character corresponding to the target trajectory, it sends a target trajectory unrecognizable command to the display device so that the display device can display unrecognizable characters. For example, the steering wheel switch controller sends a target trajectory unrecognizable command to the central control screen so that the central control screen can display unrecognizable characters.

[0080] In the above embodiments, after generating the control command for the functional device corresponding to the target character, the vehicle steering wheel switch control device sends a function display command to the display device so that the display device can show the icon of the function of the functional device corresponding to the target character. For example, after generating the function control command corresponding to the number "5", the vehicle controller of the vehicle steering wheel switch control device sends a function display command to the head-up display. After receiving the function display command sent by the vehicle controller, the head-up display shows the deceleration icon corresponding to the number "5".

[0081] In the above embodiment, after recognizing the corresponding target character on the target trajectory, the vehicle steering wheel switch control device determines whether the vehicle is in motion. If the vehicle is in motion, it generates a control command for the functional device corresponding to the target character. If the vehicle is not in motion, it determines whether the control command for the functional device corresponding to the target character to be generated is a static command. If the control command for the functional device corresponding to the target character to be generated is not a static command, it sends an unexecutable function command to the display device so that the display device can display the content of the unexecutable function of the functional device corresponding to the target character. Here, the static command is an command that can be executed when the vehicle is not in motion. If the control command for the functional device corresponding to the target character to be generated is a static command, it generates a control command for the functional device corresponding to the target character. The control command includes dynamic commands and static commands. Static commands are commands that can be executed when the vehicle is not in motion, i.e., commands unrelated to vehicle driving, such as turning off the vehicle and locking the doors. Dynamic commands are commands related to vehicle driving, such as commands related to vehicle acceleration, deceleration, cruise control, and automatic driving.

[0082] Figure 2 This is a flowchart illustrating another vehicle steering wheel switch control method provided as an exemplary embodiment of this application. Figure 2 As shown, the vehicle is equipped with a steering wheel switch controller, a vehicle controller, and a smart cockpit domain controller. The method includes:

[0092] S210: The intelligent cockpit domain controller determines whether the control command to be generated is a static command. If yes, then execute step S212; otherwise, execute step S214.

[0093] S211: The vehicle controller generates control instructions for the functional devices corresponding to the target character;

[0094] S212: The intelligent cockpit domain controller generates control instructions for the functional devices corresponding to the target character;

[0095] S213: The vehicle controller sends an instruction for an unexecutable function to the central control screen or head-up display, and displays the content of the unexecutable function.

[0096] S214: The intelligent cockpit domain controller sends an instruction for an unexecutable function to the central control screen or head-up display, and displays the content of the unexecutable function.

[0097] S215: The vehicle controller or intelligent cockpit domain controller sends a target trajectory recognition failure command to the central control screen or head-up display so that the display device can show the target trajectory recognition failure content.

[0098] In this embodiment, the execution steps of the above method can be found in the descriptions of the corresponding parts of the foregoing embodiments, and will not be repeated here.

The user first needs to activate the touchscreen, then input the target trajectory by handwriting on the touchscreen, and after the target trajectory is identified as a target character, the function of the corresponding functional device is executed, reducing the driver's misoperation.
