The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic flowchart of a vehicle steering wheel switch control method according to an exemplary embodiment of the present disclosure. As shown in fig. 1, the method includes:

s101: collecting a target track input by a user on a touch screen on a vehicle steering wheel;

s102: identifying whether the target track has corresponding target characters; if the corresponding target character exists in the recognized target track, executing step S103, and if the corresponding target character does not exist in the recognized target track, executing step S104;

s103: generating a control instruction of a functional device corresponding to the target character to execute the function of the functional device corresponding to the target character;

s104: and sending a target track unrecognizable instruction to the display device so that the display device can display the content which cannot be recognized by the characters.

In the present embodiment, the executing subject of the method is an on-board device disposed on a vehicle, for example, one or more of a steering wheel switch controller, a vehicle control unit, and an intelligent cockpit area controller. The application does not limit the above embodiments, and the embodiments can also be a personal computer, a tablet computer, an intelligent sound box, an intelligent wearable device and the like.

In this embodiment, two touch screens are respectively disposed on both sides of a steering wheel of a vehicle, and a user operates the touch screens on both sides with the left and right hands, respectively. The number of this application to the touch-sensitive screen does not limit, and the quantity of touch-sensitive screen also can set up to single or more, and simultaneously, this application does not limit to the position that sets up of touch-sensitive screen, and the touch-sensitive screen can set up in the middle part of vehicle steering wheel.

In this embodiment, the correspondence between the characters and the functions of the functional devices needs to be preset. One way of doing this is to set the correspondence of characters to functions of the functional device in response to a function setting operation. Optionally, a function setting interface is displayed on the display device, wherein the function setting interface comprises at least one function; taking the selected function as a first function in response to the selection operation of the at least one function; and responding to the operation of inputting the first character by handwriting on the touch screen, and establishing the corresponding relation between the first character and the first function. The display device can be a central control screen or a head-up display. It should be noted that, the user in the embodiment of the present application may be a driver, a passenger, or another user.

For example, in order to ensure that the function setting operation is not accidentally triggered by a user, any touch screen on two sides of a vehicle steering wheel needs to be pressed for a long time each time the function setting operation is executed, a steering wheel switch controller detects the operation of pressing the touch screen for a long time by the user, a vibration instruction is sent to the touch screen, and the touch screen vibrates to prompt the user; the central control screen display function sets a confirmation control, a trigger operation of a user on the function setting confirmation control is responded, a function setting interface is displayed on the central control screen, a function area to be selected is arranged on the left side of the central control screen, and at least one function is displayed in the function area to be selected. The steering wheel switch controller responds to the selection operation of a user on at least one function, the selected function serves as a first function, the steering wheel switch controller responds to the operation that the user inputs a first character on the touch screen by handwriting, after the first character is input, the user presses any one of the touch screens on two sides of the vehicle steering wheel for a long time, the steering wheel switch controller detects the operation that the user presses the touch screen for a long time, a vibration instruction is sent to the touch screen, and the touch screen vibrates to prompt the user. Meanwhile, the first function is moved to the right area of the central control screen, the function setting operation of the first function is completed, and the function setting operations of other functions are performed one by one until all the function settings are completed. The steering wheel switch controller responds to the triggering operation of the preset ending control by a user and closes the function setting operation.

In the present embodiment, after the correspondence between the characters and the functions of the functional device is preset by the user, the correspondence between the characters and the functions of the functional device can also be canceled. One way to achieve this is for the steering wheel switch controller to cancel the correspondence of the characters to the functions of the functional devices in response to a function cancel operation. Optionally, a function cancelling interface is displayed on the display device, wherein the function cancelling interface comprises at least one function with the established corresponding relationship; responding to the selection operation of the at least one function with the established corresponding relation, and taking the selected function as a second function; and the steering wheel switch controller responds to the operation of inputting a second character corresponding to the second function by handwriting on the touch screen, and releases the corresponding relation between the second function and the second character.

For example, before the function setting operation is finished, the user singly hits the function with the established corresponding relation on the right side of the control screen, the steering wheel switch controller responds to the selection operation of the user on at least one function with the established corresponding relation, the selected function is used as a second function, the steering wheel switch controller responds to the operation of inputting a second character corresponding to the second function by handwriting on the touch screen, after the user inputs the second character, the user presses any one of the touch screens on the two sides of the vehicle steering wheel for a long time, the steering wheel switch controller detects the operation of pressing the touch screen for a long time by the user, a vibration instruction is sent to the touch screen, and the touch screen vibrates to prompt the user. Simultaneously, the second function is moved to the left candidate area; after the function setting operation is finished, the steering wheel switch controller detects the operation of pressing the touch screen for a long time by a user, and sends a vibration instruction to the touch screen, and the touch screen vibrates to prompt the user; the steering wheel switch controller responds to the selection operation of a user on at least one function with the established corresponding relation, the selected function is used as a third function, the steering wheel switch controller responds to the operation of inputting a third character corresponding to the third function in a handwriting mode on the touch screen, after the user inputs the third character, the user presses any one of the touch screens on two sides of the vehicle steering wheel for a long time, the steering wheel switch controller detects the operation of pressing the touch screen for a long time by the user, a vibration instruction is sent to the touch screen, and the touch screen vibrates to prompt the user. At the same time, the third function is moved to the left candidate area.

Optionally, the numeric characters correspond to driving-related functions (e.g., vehicle acceleration, deceleration, cruise, and auto drive, etc.), and the alphabetic characters correspond to entertainment or other non-driving-related functions (volume up, volume down, music play last, music play next, mute, and voice). Target characters in this application include, but are not limited to: the numbers 0-9, letters other than I/L/O/Q/T/U/Z among the letters A-Z, do not support combinations of numbers, combinations of letters, and combinations of letters and numbers to improve recognition rate.

In this embodiment, the vehicle steering wheel switch control device monitors an activation operation of a user on a touch screen on the vehicle steering wheel, and sends an activation instruction to the touch screen to activate the touch screen, for example, the touch screen may be activated from a sleep state or a power-off state. After a user inputs a target track by handwriting on the touch screen, the vehicle steering wheel switch control device collects the target track input by handwriting on the touch screen on the vehicle steering wheel and identifies whether the target track is a preset target character. The method can be realized by calculating the similarity between the target track and a plurality of preset characters one by one and selecting the preset character with the maximum similarity as the target character.

In the above embodiment, the user's activation operation of the touch screen on the steering wheel of the vehicle includes any one of: long press, double click and continuous click.

In the above embodiment, the vehicle steering wheel switch control device sends the prompt instruction to the touch screen after the touch screen sends the activation instruction to activate the touch screen, so that the touch screen executes the activation prompt action. Wherein activating the cue action comprises at least one of: vibration, screen brightness change and playing prompt voice. The screen brightness change comprises the screen brightness increase and the screen brightness decrease after the screen is switched from the black screen to the bright screen. A prompt voice, e.g., a voice that "the touch screen has been activated" is played.

One example of the touch screen activation is that the vehicle steering wheel switch control device responds to a long-press operation of the touch screen on the vehicle steering wheel by a user, and the touch screen performs a vibration action to prompt the user that the touch screen is activated.

In the above embodiment, after recognizing that the target trajectory is the preset target character, the vehicle steering wheel switch control device generates a control instruction of the functional device corresponding to the target character to execute the function of the functional device corresponding to the target character; and after the vehicle steering wheel switch control device does not recognize the target character corresponding to the target track, sending a target track unidentifiable instruction to the display device so that the display device can display the content of the unidentifiable character. For example, the steering wheel switch controller sends a target track unrecognizable instruction to the central control screen, so that the central control screen displays that the characters cannot recognize the content.

In the above-described embodiment, the vehicle steering wheel switch control device, after generating the control instruction of the functional device corresponding to the target character, sends the function display instruction to the display device for displaying the icon of the function of the functional device corresponding to the target character on the display device. For example, the vehicle control unit of the vehicle steering wheel switch control device generates a function control command corresponding to the number "5" and then transmits a function display command to the head-up display, and the head-up display displays a deceleration icon corresponding to the number "5" upon receiving the function display command transmitted by the vehicle control unit.

In the above embodiment, the vehicle steering wheel switch control device determines whether the vehicle is in a traveling state only after recognizing that the target track has the corresponding target character, and generates the control command of the functional device corresponding to the target character if the vehicle is in the traveling state. If the vehicle is not in a driving state, judging whether a control instruction of a functional device corresponding to the target character to be generated is a static instruction or not; if the control instruction of the functional device corresponding to the target character to be generated is not a static instruction, sending an unexecutable functional instruction to a display device so that the display device can display the content of the unexecutable function of the functional device corresponding to the target character, wherein the static instruction is an instruction which can be executed when the vehicle is not in a running state; and if the control instruction of the functional device corresponding to the target character to be generated is a static instruction, generating the control instruction of the functional device corresponding to the target character. The control command includes a dynamic command and a static command, the static command is a command that can be executed when the vehicle is not in a driving state, that is, a command that is not related to vehicle driving, such as closing the vehicle and locking a door, and the dynamic command is a command related to vehicle driving, such as a command related to vehicle acceleration, deceleration, cruising, and automatic driving.
