[0064] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0065] To make the objectives, technical solutions, and advantages of this application clearer, the following description will be provided in conjunction with the accompanying drawings and specific embodiments.

[0066] like Figure 1 As shown, in one embodiment of the present invention, Figure 1 The implementation flow of the method for switching control of the steering wheel control buttons is shown below:

[0067] S101: When a control switch event trigger signal is detected, determine the current control terminal and the target control terminal; the current control terminal is the control terminal that currently has the authority to respond to the control button; the target control terminal is the control terminal that will soon be granted the authority to respond to the control button.

[0068] In this embodiment, the executing entity is the ECU (Electronic Control Unit) on the vehicle. The ECU is connected to each control terminal of the steering wheel control button, and each control terminal adopts a different control system.

[0069] The current control terminal has the authority to respond to steering wheel control button operations, and can collect signals from the steering wheel control buttons and respond to their control. The target control terminal is the next control terminal to have the authority to respond to steering wheel control button operations.

[0070] For example: the current control terminal is the multimedia control terminal, the target control terminal is the instrument control terminal, and the control switching event trigger signal can be the signal corresponding to the pressed / released state of the control switching button. When it is determined that the control switching button is pressed, the control terminal responding to the steering wheel button switch from the multimedia control terminal to the instrument control terminal. At this time, if the user controls the steering wheel button again, the multimedia control terminal will no longer respond to the steering wheel button control, but the instrument control terminal will respond to the steering wheel button control.

[0071] S102: Send a control switching instruction to the current control terminal; wherein, the control switching instruction is used to indicate that the control authority of the responder's control button is switched from the current control terminal to the target control terminal.

[0072] In this embodiment, after determining the current control terminal and the target control terminal, the ECU sends a control switching command to the current control terminal, and the current control terminal releases the authority to control the response control button to the target control terminal according to the control switching command.

[0073] S103: When it is determined that the target control terminal has successfully obtained the right to respond to the steering wheel control button, the corresponding steering wheel control button control right prompt flag of the target control terminal is displayed.

[0074] Specifically, after the current control terminal and the target control terminal complete the switch of authority to respond to the steering wheel control buttons, the current control terminal will return a success release signal to the ECU. After receiving the success release signal, the ECU determines that the target control terminal has successfully acquired the authority to respond to the steering wheel control buttons and displays the steering wheel control button control authority prompt flag corresponding to the target control terminal to prompt the user about the current control terminal responding to the steering wheel control buttons.

[0075] In practical applications, control buttons such as Figure 2 As shown, the controls include up, down, left, and right page buttons, and an confirmation button. The control terminals that use the steering wheel buttons can include, but are not limited to, multimedia control terminals and instrument cluster control terminals. The instrument cluster control terminal's functions include, but are not limited to, switching the trip computer page, alarm querying, multimedia and Bluetooth phone display, and navigation display. The multimedia control terminal's functions include, but are not limited to, a mute button, page switching, track skipping button, voice control, call answering and hanging up buttons, audio source switching, and enabling / disabling cruise control / adaptive cruise control, setting cruise speed, and enabling / disabling lane departure / keeping / centering systems. Users can switch between various functions on the instrument cluster control terminal or multimedia control terminal using the up, down, left, and right page buttons and the confirmation button. Switching control permissions via the steering wheel buttons will toggle the control permissions for the up, down, left, and right page buttons and the confirmation button between the multimedia control terminal and the instrument cluster control terminal.

[0076] As can be seen from the above embodiments, this embodiment can realize the control of the same set of steering wheel control buttons by different control terminals through the above solution, realize the switching and display of control rights between multiple control terminals of the steering wheel control buttons, thereby avoiding the problem of too many steering wheel control buttons causing inconvenience to users.

[0077] In one possible embodiment, prior to S101, the method provided in this embodiment further includes:

[0078] The control switching event is determined by monitoring the level of the control switching button. If the control switching button is at a high level, the control switching event is considered to have been triggered.

[0079] In this embodiment, Figure 3 The diagram illustrates an application scenario of the steering wheel control button switching method, such as... Figure 3As shown, the hardware module for implementing the steering wheel control button switching method includes a control switching button 10, a combination switch 20, an ECU 30, and a vehicle computer display screen 40. The control switching button 10 is located on the steering wheel. The combination switch 20 is communicatively connected to both the control switching button 10 and the ECU 30, and is used to hardwire the acquisition of the voltage level of the control switching button 10, converting the high and low voltage levels into CAN signals and sending them to the ECU 30. The ECU 30 determines whether a control switching event is triggered based on the CAN signals.

[0080] Specifically, a high-level signal corresponds to the control switching button being pressed, and a low-level signal corresponds to the control switching button being released. The ECU determines that a control switching event is triggered when the control switching button is at a high level via the CAN signal.

[0081] To facilitate understanding, this embodiment provides an example of an application scenario. In this specific application scenario, the current control terminal is a multimedia control terminal, and the target control terminal is an instrument control terminal. When the level is high, the control terminal responding to the control button switches from the multimedia control terminal to the instrument control terminal; when the level is low, the control terminal responding to the control button remains unchanged as the multimedia control terminal.

[0082] The above method can achieve the switching of control permissions for the steering wheel control buttons by adding a physical button, making it easier for users to operate.

[0083] In one possible embodiment, another method for determining whether a control switch event has been triggered could be:

[0084] Obtain the voice control information entered by the user. If the voice control information contains keywords related to the control switch event, then the control switch event is determined to be triggered.

[0085] Specifically, if the semantic recognition algorithm identifies the keyword "control switching" or its synonym in the voice information, then the control switching event is determined to be triggered.

[0086] This embodiment uses voice recognition to determine whether a control switching event has been triggered, which makes it convenient for users to switch control of the steering wheel buttons while driving, further simplifying the buttons on the steering wheel. At the same time, controlling control switching via voice while driving is safer.

[0087] In one possible embodiment, determining the specific implementation process of the current control terminal includes:

[0088] Obtain the control authority flag information of each control terminal; the control authority flag information is used to indicate whether the control terminal has the authority to respond to the control button;

[0089] The current control terminal is determined based on the control authority flag information of each control terminal.

[0090] Specifically, each control terminal has a control authority flag. When the control authority flag is at the first value, it indicates that it has the authority to respond to the control buttons. When the control authority flag is at the second value, it indicates that it does not have the authority to respond to the control buttons. The first value is not equal to the second value.

[0091] For example, the first value is 1 and the second value is 0.

[0092] Specifically, the process of switching permissions for steering wheel button control between the current control terminal and the target control terminal includes:

[0093] When the current control terminal receives a control switch command, it sends a control switch request to the target control terminal. The target control terminal sets its own control flag to 1 based on the control switch request, and after the control flag is set to 1, it responds to the steering wheel button control and returns a ready signal to the current control terminal. When the current control terminal receives the ready signal from the target control terminal, it sets its own control flag to 0. Upon detecting that the control flag is 0, the current control terminal sends a release success signal to the ECU. The ECU determines that the target control terminal has successfully acquired the authority to respond to the steering wheel button control based on the release success signal. If the current control terminal sends a release failure signal or does not send any feedback signal to the ECU, the ECU maintains the current steering wheel button control authority indicator.

[0094] In one possible embodiment, the specific implementation process for determining the target control terminal includes:

[0095] Obtain any control terminal other than the current control terminal as the target control terminal;

[0096] Alternatively, the next control terminal in the control order list after the current control terminal can be used as the target control terminal. The control order list records the order of each control terminal.

[0097] Alternatively, the target control terminal can be extracted from the user's voice control information.

[0098] Specifically, when determining the target control terminal based on the control order list, each control terminal is first assigned a different priority, and then sorted in descending order of priority to obtain the control order list. After the vehicle is powered on, the steering wheel control button is controlled by the highest priority control terminal by default. When a control order switching event is detected, the next control terminal in the control order list after the current control terminal is taken as the target control terminal. The control order list can be used cyclically; that is, if the current control terminal is the lowest priority control terminal in the control order list, and a control order switching event is detected, the corresponding target control terminal is the highest priority control terminal in the control order list.

[0099] Specifically, the process of extracting the target control terminal from voice control information includes:

[0100] Keywords and semantic information are extracted from voice control information using a semantic recognition algorithm, and the target control terminal is determined based on the keywords and semantic information.

[0101] For example, when the voice control information is to switch the multimedia control terminal to the instrument control terminal, the semantic recognition algorithm can identify the sentence structure "switch A to B" and extract the keyword "instrument control terminal" corresponding to B as the target control terminal.

[0102] As can be seen from the above embodiments, compared with random switching and sequential switching, the method of determining the target control terminal through voice recognition can conveniently and quickly grant the user the control terminal that responds to the steering wheel button, and can reduce the number of steering wheel buttons.

[0103] In one possible embodiment, the specific implementation process of S101 includes:

[0104] If a control switch event trigger signal is detected when the vehicle is powered on, the current control terminal and the target control terminal are determined.

[0105] Specifically, when the vehicle is powered on (i.e., the engine ignition signal KL15 is ON), if a control switch event trigger signal is detected, the ECU will respond to the control switch control, determining the current control terminal and the target control terminal. When the vehicle is powered off (i.e., the engine ignition signal KL15 is OFF), if a control switch event trigger signal is detected, the ECU will not respond to the control switch control and will not execute subsequent procedures.

[0106] Furthermore, if the vehicle is powered on but the target control terminal is not started, and a control switch event trigger signal is detected, the ECU will not respond to the control switch control and will not execute subsequent procedures.

[0107] In one possible embodiment, the steering wheel control button control authority indication indicator includes: a steering wheel control button control authority switching pop-up window; the specific implementation process of S103 includes:

[0108] If the first card is displayed on the vehicle computer screen, and it is determined that the target control terminal has successfully obtained the permission to respond to the steering wheel control button, then a pop-up window for switching the steering wheel control button right of the target control terminal will be displayed.

[0109] If the second card is displayed on the vehicle's computer screen, it is determined that the target control terminal has successfully acquired the authority to respond to the steering wheel control buttons, and the timer starts; if the second card disappears and the timer duration is less than or equal to the first preset duration, a steering wheel control button control switch pop-up window is displayed.

[0110] The first card is the card with a priority less than or equal to the steering wheel control button switching pop-up window; the second card is the card with a priority greater than the steering wheel control button switching pop-up window.

[0111] In this embodiment, the steering wheel control button control authority indication includes a steering wheel control button control authority switching pop-up window and a steering wheel control button control authority indicator light.

[0112] In this embodiment, the pop-up window for switching control of the steering wheel control buttons includes a steering wheel control button icon, an indicator arrow, and a target control terminal, indicating that the authority to respond to steering wheel control button commands has been switched to the target control terminal. Specifically, Figure 4 A pop-up window showing the switching of control rights for the steering wheel buttons corresponding to the multimedia control terminal is displayed, indicating that the control terminal currently responding to steering wheel button controls has been switched to the multimedia control terminal. Figure 5 A pop-up window showing the switching of control rights for the steering wheel control buttons corresponding to the instrument control terminal is displayed, indicating that the control terminal currently responding to steering wheel control button control has been switched to the instrument control terminal.

[0113] In this embodiment, the steering wheel control button switching pop-up is a transient card. It appears for a third preset time and then disappears, restoring the original card. The first card includes, but is not limited to, charging, driving, multimedia, telephone, and display mode cards. The second card includes, but is not limited to, alarm pop-ups. If, during the display of the steering wheel control button switching pop-up, another first card is triggered, the steering wheel control button switching pop-up disappears, the first card is displayed, and the steering wheel control button switching pop-up does not reappear after the first card disappears.

[0114] In one embodiment, if a button press event is detected during the display of the steering wheel control switch pop-up, the steering wheel control switch pop-up is blocked, and the display returns to the card displayed before the steering wheel control switch pop-up pops up.

[0115] For example, the first preset duration can be set to 3 seconds. If the ECU receives a release success signal from the current control terminal during the display of the second card, the steering wheel control button control switch pop-up window will not be displayed immediately. Instead, the timing will start from the moment the release success signal is received and end at the moment the second card disappears. It will check whether the timing duration from the start time to the end time is less than the first preset duration. If so, the steering wheel control button control switch pop-up window will be displayed. If not, the steering wheel control button control switch pop-up window will not be displayed, and the screen will switch back to the card before the second card popped up.

[0116] With the above settings, this embodiment can interrupt the display of a card with lower priority and display a pop-up window for switching steering wheel control buttons during the display of such cards; and will not display the pop-up window for switching steering wheel control buttons during the display of higher priority and more important information, so as to avoid the situation where important information is not displayed due to the display of the pop-up window for switching steering wheel control buttons, thereby optimizing the display effect of various vehicle information and improving driving safety.

[0117] In one possible embodiment, the method provided in this embodiment further includes:

[0118] If the bus signal used to monitor the control switching event is lost, and the loss duration is less than or equal to the second preset duration, the current steering wheel control button control prompt flag will be maintained.

[0119] If the bus signal used to monitor control switching events is lost, and the loss duration exceeds the second preset duration, the steering wheel control button control status indicator will not be displayed.

[0120] In this embodiment, if the ECU does not receive the CAN signal sent by the combination switch, and the CAN signal loss duration is less than or equal to the second preset duration, the vehicle computer display will continue to show the current steering wheel control button control status indicator. If the loss duration exceeds the second preset duration, no steering wheel control button control status indicator will be displayed to remind the user of signal loss. After the CAN signal is lost, if the ECU receives n valid CAN signals again, the steering wheel control button control status indicator will be displayed again, and the subsequent process will continue according to the steering wheel control button control switching method.

[0121] Specifically, the second preset duration can be 10 collection cycles, where n≥1.

[0122] In one possible embodiment, the steering wheel control button control authority indicator further includes: a steering wheel control button control authority indicator light; the specific implementation process of S103 may also include:

[0123] The control button indicator light switches to the color corresponding to the target control terminal.

[0124] In this embodiment, the steering wheel control button control authority indicator light includes multiple colors, with each color corresponding to a different control terminal. Users can identify the control terminal currently authorized to respond to steering wheel control button commands based on the color of the indicator light. For example, when the steering wheel control button indicator light is green, it indicates that the control terminal authorized to respond to steering wheel control button commands is the instrument control terminal; when the indicator light is gray, it indicates that the control terminal authorized to respond to steering wheel control button commands is the multimedia control terminal.

[0125] As can be seen from the above embodiments, this embodiment simplifies the number of buttons on the steering wheel and reduces the learning cost for users by adding a control switching button and a steering wheel button control prompt. It is applicable to any vehicle model or intelligent cockpit interaction system that adopts a steering wheel button reuse layout.

[0126] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
