Abstract
Description
Technical Field
[0001] This disclosure relates to the technical field of vehicles, and more specifically, to a method, apparatus, computing device, steering wheel control panel assembly, vehicle including the steering wheel control panel assembly, and computer-readable storage medium for triggering button functions. Background Technology
[0002] The steering wheel assembly is a crucial component of a vehicle. It comprises the steering wheel frame assembly and the steering wheel control panel assembly. The control panel assembly is mechanically mounted to the frame assembly and includes a panel for driver operation via buttons. The steering wheel frame primarily controls the vehicle's direction of travel. While driving, the driver can use the panel to perform other functions, such as honking the horn, activating or deactivating driver assistance features, changing driving modes, adjusting the audio volume, and setting the air conditioning temperature.
[0003] Currently, the control panel can integrate a button function area and multiple character buttons. The button function area is located in the middle of the panel, while the character buttons (such as adjusting volume, temperature, activating or deactivating driver assistance functions, etc.) are located on both sides of the button function area, between the steering wheel frame and close to the driver's hands. When the driver touches and presses a character button, the vehicle's control system executes the function corresponding to that character button. In some situations, when the driver is steering, they may subconsciously ignore the steering wheel button function area, leading to the hand, especially the palm, touching the button function area during hand-to-hand maneuvering. This can cause the button functions to be accidentally triggered, potentially leading to traffic violations and driving safety hazards, while also reducing the user experience. Summary of the Invention

[0021] First refer to Figure 1a and Figure 1b Explain the control principle of the steering wheel control panel component in the prior art. Figure 1a A schematic diagram of a steering wheel assembly in the prior art is shown. Figure 1bA perspective view of a steering wheel control panel assembly in the prior art is shown.
[0022] Also refer to Figure 1a and Figure 1b In the prior art, the steering wheel assembly 10 includes a steering wheel frame assembly 11 and a steering wheel control panel assembly 12. The steering wheel control panel assembly 12 is mechanically ( Figure 1a (Not shown) is mounted onto the steering wheel frame assembly 11. The steering wheel control panel assembly 12 includes a panel 121, the central part of which is a horn function area 122. Several touch buttons (such as character buttons, used to adjust volume, temperature, activate or deactivate driver assistance functions, etc.) are provided on both sides of the horn function area 122. A touch detection film is installed (e.g., tightly adhered) on the back side of the panel 121. Figure 1b The shaded areas in the image represent the touch button detection areas 123a or 123b on the touch detection membrane, corresponding to each touch button. The touch detection membrane generates a detection signal and provides it to the control chip of the steering wheel control panel assembly 12.
[0023] When a touch is detected and pressed through the touch detection membrane at each touch button detection area, the control chip sends a corresponding function trigger signal to the vehicle's control system to execute the function. However, when the vehicle is turning, the driver usually needs to apply control force to the steering wheel. At this time, this control force inevitably overflows to the edge of the panel. Therefore, it is necessary to prevent the touch button's function from being triggered when the driver accidentally touches the touch button simply because of turning.
[0024] In view of this, this disclosure proposes a steering wheel control component and a method for accurately preventing accidental triggering of button functions. The content of this disclosure will be described below with reference to several embodiments.
[0025] Next reference Figure 2 and Figure 3 , Figure 2 A perspective view of a steering wheel control panel assembly according to an embodiment of the present disclosure is shown. Figure 3 A schematic flowchart of a key function triggering method according to one embodiment of the present disclosure is shown.
[0026] exist Figure 2 and Figure 3In this embodiment, the steering wheel control panel assembly 20 includes a panel assembly and two smart switch assemblies (not shown) located on the left and right sides respectively. The panel assembly includes a panel 201. The panel 201 has two first regions 202a and 202b located on the left and right sides respectively, and a second region 203 located in the middle of them. The first regions 202a and 202b serve as operating surfaces for touch buttons, and the second region 203 serves as operating surfaces for button functions. Touch detection films are provided (e.g., adhered) on the back side of the panel 201 at positions corresponding to the two first regions 202a and 202b. The touch detection films can be, for example, capacitive touch films, which are tightly adhered to the back side of the panel 201. The capacitive touch films can be of the self-capacitive or mutual-capacitive type. A plurality of touch buttons are arranged in the first regions 202a and 202b respectively. Correspondingly, the touch detection films have a plurality of corresponding button detection areas 210a and 210b for detecting the touch of an object (e.g., the driver) on the touch buttons. In addition, the touch detection membrane also has multiple non-button detection areas that do not overlap with the button detection areas 210a and 210b. Figure 2 The diagram exemplarily illustrates three non-button detection areas 211a and 211b on each of the left and right sides, used to detect touches made by an object on the blank areas between the touch buttons in the first areas 202a and 202b. In other embodiments, the touch detection film may have other numbers of non-button detection areas, such as four or six. The panel 201 may be made of a low-strength and somewhat elastic material, such as TPO plastic.
[0027] The following are also for reference Figure 3 This document describes a method for triggering button functions according to embodiments of the present disclosure. Figure 3 A schematic flowchart of a key function triggering method according to an embodiment of the present disclosure is shown. The method 300 can, for example, be... Figure 2 The control chip of the intelligent switch component can be used for execution, or it can be executed by other computing devices, such as the vehicle's control system.
[0028] Method 300 is used for a steering wheel control panel assembly for a vehicle. The steering wheel control panel assembly includes a panel having a first area near the edge of the steering wheel and a second area near the center of the steering wheel, and a touch detection device (such as...) disposed on the back side of the panel and corresponding to the first area. Figure 3 (a touch detection membrane in the middle), wherein the button is located in the first area.
[0029] refer to Figure 3 In step 301, the touch detection device detects the object's touch on the non-button area of the first region and obtains the touch detection result.
[0030] like Figure 2As shown, the touch detection film has multiple button detection areas 210b corresponding to the touch buttons on panel 201, and three non-button detection areas 211b that do not overlap with the button detection areas 210b. Therefore, the control chip of the smart switch detects touches made by an object on areas other than the touch buttons in the first region 202b via the non-button detection areas 211b. The touch detection result includes the touch detection result for each non-button detection area 211b.
[0031] In step 302, based on the touch detection result, it is determined whether the object has touched the non-button area of the first region.
[0032] In step 303, the control chip of the smart switch detects the touch of the object on the corresponding touch button in the first area 202b via the button detection area 210b. That is, the touch detection device detects the object pressing the button and obtains the button press detection result to determine whether the object has pressed the button.
[0033] It should be noted that step 303 does not necessarily have to be executed after steps 301 and 302, but can be executed independently of steps 301 and 302, for example, in parallel or in reverse order.
[0034] In step 304, if it is determined that the object did not touch the non-button area of the first region during a first time period before pressing the button, the button function is triggered. This avoids accidental touches.
[0035] exist Figure 3In this embodiment, preferably, the object is determined to have pressed the button if the button press detection result is greater than 1 Newton. More preferably, the object is determined to have pressed the button if the button press detection result is greater than 2 Newtons. Furthermore, preferably, in some embodiments, the duration of the first time period does not exceed 1 second. More preferably, in some embodiments, the duration of the first time period does not exceed 400 milliseconds. Here, the button includes the outermost character function button near the edge of the steering wheel. Of course, those skilled in the art should understand that the button can also include other buttons. In other words, if the driver, during operation, such as when turning, operates the steering wheel and first touches a non-button area and then touches a button area, this is usually a misoperation, so the button function is not triggered. Correspondingly, if the driver, during operation, such as when turning, operates the steering wheel and simultaneously touches a non-button area and then touches a button area, this is also usually a misoperation, so the button function is not triggered. The inventors of this disclosure realized that the button function is only triggered when it is determined that the object has not touched the non-button area of the first region during the first time period before pressing the button, which ensures that the button function is correctly activated.
[0036] exist Figure 3 In this embodiment, the control chip can generate a button function trigger signal and send it to the vehicle's control system. After receiving the button function trigger signal, the control system controls the function corresponding to the button and returns end information to the control chip.
[0037] In the above embodiments, the button functions on the steering wheel control panel can be accurately prevented from being accidentally triggered without increasing hardware costs, thereby improving the control performance of the steering wheel control panel, avoiding potential traffic violations and driving safety hazards, improving the user's driving experience, and leaving more design space for the appearance of the panel.
[0038] This disclosure also proposes a button function triggering device. The modules of the button function triggering device can be implemented using software, hardware (e.g., integrated circuits, FPGAs, etc.), or a combination of both. This button function triggering device is used in a vehicle's steering wheel control panel assembly, which includes a panel having a first area near the edge of the steering wheel, and a touch detection device disposed on the back side of the panel and corresponding to the first area, wherein the button is disposed in the first area.

For example, in some embodiments, the button function triggering device 400 includes a touch detection module 410 configured to detect touch of an object on a non-button area of the first region via the touch detection device and obtain a touch detection result; a touch judgment module 420 configured to determine, based on the touch detection result, whether the object has touched a non-button area of the first region; a press detection judgment module 430 configured to detect the object's press on the button via the touch detection device and obtain a button press detection result to determine whether the object has pressed the button; and a button function triggering module 440 configured to trigger the button function if it is determined that the object has not touched a non-button area of the first region within a first time period before pressing the button.
[0040] Preferably, in some embodiments, if the button press detection result is greater than 1 Newton, it is determined that the object has pressed the button. More preferably, in some embodiments, if the button press detection result is greater than 2 Newtons, it is determined that the object has pressed the button.
[0041] Furthermore, preferably, in some embodiments, the duration of the first time period does not exceed 1 second. More preferably, in some embodiments, the duration of the first time period does not exceed 400 milliseconds. Here, the button includes the outermost character function button near the edge of the steering wheel.
[0042] In some embodiments, the first region includes at least one touch button, and the touch detection device includes a touch detection film having at least one corresponding button detection area and at least one non-button detection area that does not overlap with the button detection area.

The memory 502 stores computer-executable instructions, which, when executed, cause the processor 501 to perform the methods described in the above embodiments. The processor 501 and the memory 502 are connected to each other via a bus, and an input / output (I / O) interface is also connected to the bus.
