Description

Technical Field

[0001] This invention relates to the field of touch control technology, and more particularly to a touch button for a vehicle and a method for preventing accidental touch button operation. Background Technology

[0002] Touch buttons, as a user-friendly human-computer interaction component, are widely used in various fields (e.g., the automotive industry). For example, although users can input vehicle operations by touching the display screen, touch buttons are usually still located below the screen. These could be buttons to return to the home page, to bring up a map, or to open a media player. These touch buttons enable simple and direct interaction between the user and the vehicle.

[0003] However, when a user touches the display screen with one finger (e.g., the index finger), their other bent fingers may rest on the touch buttons below the screen, potentially touching those buttons. Furthermore, as the user's index finger moves across the screen, their other bent fingers may also move across these touch buttons. All of this can lead to accidental touch button operations, impacting the user experience. A similar situation may occur when a user operates the gear shift mechanism, potentially touching touch buttons around it (e.g., the auto-hold button).

[0004] Therefore, there is an urgent need for a touch button for vehicles that can prevent accidental operation, as well as a method for preventing accidental operation of the touch button.

[0005] The above description of the background technology is only for the purpose of facilitating a deeper understanding of the technical solution of the present invention (the technical means used, the technical problems solved, and the technical effects produced, etc.), and should not be regarded as an admission or in any form an implication that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a touch button for a vehicle and a method for preventing accidental operation of the touch button, which can effectively improve the anti-accidental operation of vehicle touch buttons.

[0007] According to one embodiment of the present invention, a touch button for a vehicle is provided. The touch button includes a touch film, the touch film including mutually spaced button sensing areas and non-button sensing areas located around each button sensing area. The touch button is configured to generate a touch control signal corresponding to the button sensing area when, after a second reference time, the button sensing area is triggered but the non-button sensing area is not triggered, and the same button sensing area is still triggered after a second reference time.

[0008] The touch button may include: a touch surface, the touch film being disposed inside the touch surface, the touch surface forming a button touch area corresponding to the button sensing area of ​​the touch film, and a non-button touch area corresponding to the non-button sensing area of ​​the touch film, the button touch area and the non-button touch area being configured such that: touching the button touch area triggers the button sensing area, and touching the non-button touch area triggers the non-button sensing area.

[0009] The touch membrane can be configured to generate a touch button signal when the button sensing area is triggered, and to generate a touch non-button signal when the non-button sensing area is triggered; the touch button can further include a circuit board electrically connected to the touch membrane, and is configured to receive the touch button signal and / or the touch non-button signal, and if a touch button signal is received but no touch non-button signal is received within a first reference time, and the same touch button signal is still received after a second reference time, generate a touch control signal based on the received touch button signal.

[0010] The circuit board can be configured to: determine whether a non-button touch signal is received; when a non-button touch signal is received, not generate any touch control signal; when no non-button touch signal is received, determine whether a button touch signal is received; when a button touch signal is received, determine whether a first reference time has elapsed; when the first reference time has elapsed, determine whether a non-button touch signal is received within the first reference time; when a non-button touch signal is received within the first reference time, not generate any touch control signal; when no non-button touch signal is received within the first reference time, determine whether a second reference time has elapsed; when the second reference time has elapsed, determine whether the same button touch signal is still received; when no more button touch signals are received, not generate any touch control signal; when the same button touch signal is still received, generate a touch control signal based on the received button touch signal.

[0011] The non-button sensing area may include the gap between two adjacent button sensing areas.

[0012] The touch button may further include: a front cover and a rear cover, the front cover and the rear cover forming a receiving space, and the front cover serving as a touch surface, with the touch film and circuit board disposed within the receiving space.

[0013] The front cover can form symbols at the button touch area.

[0014] According to another embodiment of the present invention, a method for preventing accidental touch button operation is provided. The touch button includes a touch film, the touch film including mutually spaced button sensing areas and non-button sensing areas located around each button sensing area. The method includes: determining whether a button sensing area is triggered and a non-button sensing area is not triggered within a first reference time; when it is determined that a button sensing area is triggered and a non-button sensing area is not triggered within the first reference time, determining whether the same button sensing area is still triggered after a second reference time; when it is determined that the same button sensing area is still triggered after the second reference time, the touch button generates a touch control signal corresponding to the button sensing area.

[0015] The steps for determining whether the button sensing area was triggered but the non-button sensing area was not triggered within the first reference time period may include: determining whether the non-button sensing area was triggered; when it is determined that the non-button sensing area was not triggered, determining whether the button sensing area was triggered; when it is determined that the button sensing area was triggered, determining whether the first reference time period has elapsed; when it is determined that the first reference time period has elapsed, determining whether the non-button sensing area was triggered within the first reference time period; when it is determined that the non-button sensing area was not triggered within the first reference time period, determining whether the button sensing area was triggered but the non-button sensing area was not triggered within the first reference time period.

[0016] The steps for determining whether the same key sensing area is still triggered after the second reference time may include: determining whether the second reference time has elapsed; when it is determined that the second reference time has elapsed, determining whether the same key sensing area is still triggered; when it is determined that the same key sensing area is still triggered, determining that the same key sensing area is still triggered after the second reference time.

[0017] The present invention adopts the above technical solution and has the following beneficial effects: The present invention improves the touch film in hardware. The improved touch film sets the surrounding area outside each button sensing area as a sensing area (referred to as the non-button sensing area). Therefore, when a user's finger touches an area outside the button touch area, unlike the prior art where no sensing area is triggered, the non-button sensing area is triggered. This hardware improvement provides a basis for preventing accidental operation of touch buttons. Furthermore, the present invention improves the control logic in software. The improved control logic determines whether only the button sensing area is triggered based on a first reference time. After determining that only the button sensing area is triggered within the first reference time, it performs a delay detection on the triggering or non-triggered state of the previously triggered button sensing area based on a second reference time. And when the button sensing area is still triggered, a touch control signal can be generated. Therefore, it can effectively improve the anti-accidental operation capability of vehicle touch buttons.

[0024] Figure 6 This is a flowchart illustrating a method for preventing accidental touch operation of buttons according to an embodiment of the present invention. Detailed Implementation

[0025] The following provides a detailed description of the embodiments of the present invention. These embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operation processes. However, the scope of protection of the present invention is not limited to the following embodiments.

[0026] Figure 1 This is a schematic diagram illustrating an example of the touch surface of a touch button located below the vehicle's display screen. Figure 1 As shown, the touch surface of the touch buttons is marked with symbols for "Home," "Map," "Search," "Media," and "Menu." During screen operation, users can identify the location of the touch area based on these symbols. In other words, the touch surface of the touch buttons forms five touch areas, and each symbol's area can be considered a touch area. For example, Figure 1 Each symbol in the text represents a button touch area.

[0027] In the prior art, in order for touch buttons to detect the user's touch action, a touch film is usually placed on the inside of the touch surface, and the touch film forms a button sensing area that corresponds one-to-one with the button touch area of ​​the touch surface. Figure 2 It is formed based on existing technology of touch film and Figure 1 A schematic diagram showing the button touch area and the corresponding button sensing area. (See diagram below.) Figure 2 As shown, the button sensing areas of the touch membrane include a "home page sensing area", a "map sensing area", a "search sensing area", a "media sensing area", and a "menu sensing area".

[0028] The controller can receive the electrical signal parameter values ​​of each button sensing area in real time to determine whether a corresponding action needs to be performed. Combined with... Figure 1 and Figure 2 For example, when a user needs to return the monitor screen to the home page, the user touches the "home" symbol. The electrical signal in the corresponding home page sensing area changes. The controller detects this change, determines that the home page sensing area has been triggered, and then executes the action of returning the monitor screen to the home page. On the other hand, when the user touches an area other than the button touch area, since the existing touch film does not have a sensing area for other areas, the electrical signal in any sensing area changes, and therefore the controller does not perform any action.

[0029] In this scenario, when a user touches the monitor screen with their index finger, their other bent fingers might be placed on the touch buttons, potentially touching the touch buttons below the screen. Furthermore, as the user's index finger moves across the screen, their other bent fingers might move across the touch buttons. For example, within a short time, the user's four fingers might touch the symbol "Media," simultaneously touching the area above it, and then move to the left, touching the gap between the "Media" and "Search" symbols. In other words, within a short period, the user's fingers continuously touched... Figure 1 In area A of the media sensor, as described above, the electrical signal in the media sensing area changes, and the controller executes the action of opening the media player on the screen. However, this is a misoperation of the touch button by the user; the action of opening the media player on the screen is not the action the user expects.

[0030] Similar situations include: when a user places their hand on the center console and flicks the gear shifter with their finger, the user is unaware that their hand is touching the touch buttons around the gear shifter until the user has finished operating the gear shifter and then removes their hand from the touch buttons.

[0031] To address this problem, the present invention provides a touch button for vehicles. Figure 3 This is a schematic diagram of a touch button for a vehicle according to an embodiment of the present invention. Figure 3 As shown, the touch button includes a touch membrane 20.

[0032] Figure 4 This is a schematic diagram of the sensing area formed by the touch film according to an embodiment of the present invention. Figure 4 As shown, the touch film 20 includes mutually spaced button sensing areas 21 and non-button sensing areas 22 located around each button sensing area 21.

[0033] Taking the touch buttons below the vehicle display screen as an example, similarly, Figure 4 The five button sensing areas 21 shown are the "Homepage Sensing Area", "Map Sensing Area", "Search Sensing Area", "Media Sensing Area" and "Menu Sensing Area".

[0034] However, the present invention does not limit the shape of the button sensing area 21 to a rectangle; the button sensing area 21 can be of any shape. Furthermore, the present invention does not limit the button sensing areas 21 to be arranged in a row; the button sensing areas 21 can be arranged in a matrix in both vertical and horizontal directions, or dispersed at any position.

[0035] Unlike existing technologies, in the touch film 20 according to an embodiment of the present invention, the surrounding area outside each button sensing area 21 is also set as a sensing area and is called a non-button sensing area 22.

[0036] In a simplified case, each non-button sensing area 22 includes a sub-area 22a located to the left of the corresponding button sensing area 21, a sub-area 22b located above the corresponding button sensing area 21, a sub-area 22c located to the right of the corresponding button sensing area 21, and a sub-area 22d located below the corresponding button sensing area 21.

[0037] Therefore, the non-button sensing area 22 includes a sub-area 22c to the right of the first button sensing area 21 and a sub-area 22a to the left of the second button sensing area 21 (which is spaced apart to the right of the first button sensing area 21). Since the gap between two adjacent button sensing areas 21 is always an area of ​​user error, therefore, as... Figure 4 As shown, preferably, sub-regions 22c and 22a can be connected and form a whole, that is, the non-button sensing area 22 includes the gap between two adjacent button sensing areas 21.

[0038] However, the present invention does not limit the non-button sensing area 22 to this. For example, the non-button sensing area 22 can be a ring-shaped area formed by connecting the ends of the sub-areas. In addition, the shape of each sub-area is not limited to a rectangle.

[0039] Back Figure 3 According to an embodiment of the present invention, the touch button includes a front cover 10 and a rear cover 30, which form a receiving space. The front cover 10 serves as a touch surface, forming a symbol at the button touch area and is configured to receive user touch. A touch film 20 is disposed within the receiving space and inside the touch surface (i.e., the inner surface of the front cover 10). The touch film 20 can be classified into several types according to its working principle, such as resistive, radio wave (e.g., surface acoustic wave), optical (infrared), inductive, capacitive, and electromagnetic. Taking a capacitive touch film as an example, the capacitive touch film can easily adhere tightly to the inner surface of an uneven housing, such as the inner surface of the front cover 10, and there will be no gap between the capacitive touch film and the inner surface of the front cover 10, thereby enabling the detection of the touch when the user touches the outer surface of the front cover 10.

[0040] In an embodiment of the present invention, similar to the prior art, the touch surface forms a button touch area corresponding to the button sensing area 21 of the touch film 20. Unlike the prior art, since the touch film 20 has a non-button sensing area 22, the touch surface corresponding to the non-button sensing area 22 of the touch film 20 forms a non-button touch area.

[0041] The working principle of triggering the sensing area of ​​a capacitive touch film is illustrated using a capacitive touch film as an example. Each sensing area of ​​a capacitive touch film includes a sensing electrode, and a distributed capacitance exists between each sensing electrode and a ground electrode. After a user's finger touches an appropriate area of ​​the touch surface, a coupling capacitance is generated between the finger and the sensing electrode. Due to the parallel relationship between this coupling capacitance and the distributed capacitance, the capacitance value between the sensing electrode and the ground electrode after the touch changes to the sum of the distributed capacitance and the coupling capacitance. This change in capacitance value between the sensing electrode and the ground electrode after the touch causes a change in the electrical signal of the sensing area, i.e., the sensing area is triggered. Therefore, based on the above working principle, the button touch area and the non-button touch area are configured as follows: touching the button touch area triggers the button sensing area 21, and touching the non-button touch area triggers the non-button sensing area 22.

[0042] Therefore, when a user's finger touches an area other than the button touch area, unlike the case where no sensing area is triggered in the prior art, in the embodiment of the present invention, the non-button sensing area 22 will be triggered, which provides a basis for preventing the touch button from being accidentally operated.

[0043] Specifically, according to an embodiment of the present invention, the touch button is configured such that: when the button sensing area 21 is triggered but the non-button sensing area 22 is not triggered within a first reference time Δt, after a second reference time T... d When the same button sensing area 21 is still triggered, the touch button generates a touch control signal corresponding to the button sensing area 21.

[0044] In other words, two conditions must be met sequentially for a touch button to generate a touch control signal. The first condition is that the button sensing area 21 is triggered within a first reference time Δt, while the non-button sensing area 22 is not triggered. For example, when using the first condition to evaluate whether a user's finger has continuously touched the button within a short period of time (less than the first reference time Δt), this condition is crucial. Figure 1 In the case of region A, it can be concluded that within the first reference time Δt, both the button sensing area 21 and the non-button sensing area 22 are triggered, and the first condition is not met. Therefore, the touch button will not generate any touch control signal, thereby preventing accidental touch button operation that could lead to unintended screen actions.

[0045] The satisfaction of the second condition is determined based on the satisfaction of the first condition. The second condition is: after the second reference time T... d The same button sensing area 21 is still triggered. That is, it is necessary to trigger it at the second reference time T. d After (also known as the touch delay time), the triggered or untriggered state of the same button sensing area 21 is determined again. If the same button sensing area 21 changes to an untriggered state, it indicates that the brief triggering of the button sensing area 21 may be a erroneous operation. The second condition is not met, and the touch button will not generate any touch control signal, thereby preventing the user from performing unwanted vehicle actions due to accidental touch button operation.

[0046] According to an exemplary embodiment of the present invention, the first reference time Δt ranges from 100ms to 200ms, and the second reference time T... d The value range is from 100ms to 200ms to ensure good anti-misoperation effect of the touch button. In addition, the first reference time Δt and the second reference time T... d Adjustments can be made based on the specific circumstances.

[0047] It should be noted that touch buttons also have a long touch, which is different from a short touch. For example, a long touch generates a different touch control signal than a short touch after 800ms. Therefore, the upper limit of the second reference time Td should be set to be less than the time required for a long touch, so as to distinguish between short touch and long touch.

[0048] The two conditions mentioned above will be described in detail below.

[0049] When the button sensing area 21 is triggered, the touch membrane 20 can generate a touch button signal, indicating that the user has touched the button touch area. Furthermore, the touch button signal can indicate specific touch button information. For example, when the home page sensing area is triggered, the touch button signal generated by the touch membrane 20 can indicate the touch button corresponding to returning the display screen to the home page (i.e.,...). Figure 1 The symbol "Homepage" was touched.

[0050] When the non-button sensing area 22 is triggered, the touch membrane 20 can generate a non-button touch signal. This non-button touch signal indicates that the user has touched a non-button touch area, i.e., the area surrounding the button touch area. Preferably, the non-button touch signal can indicate specific touch location information; for example, the non-button touch signal generated by the touch membrane 20 can indicate a touch button corresponding to the one that returns the screen to the home page (i.e.,...). Figure 1 The symbol "homepage" and the touch button that makes the map pop up on the screen (i.e. Figure 1 The gaps between the symbols ("map") were touched.

[0051] Accordingly, the touch button for a vehicle according to the present invention includes a circuit board 40 disposed within a receiving space formed by the front cover 10 and the rear cover 30, and electrically connected to the touch film 20. The circuit board 40 is configured to receive touch button signals and / or touch non-button signals from the touch film 20.

[0052] According to an embodiment of the present invention, if a touch button signal is received but no non-touch button signal is received within the first reference time Δt, then after the second reference time T... d If the same touch button signal is still received, the circuit board 40 can generate a touch control signal based on the received touch button signal.

[0053] Figure 5 This is an operation flowchart of a circuit board according to an embodiment of the present invention. Figure 5 As shown, circuit board 40 determines whether a touch-not-button signal has been received (S11). When it is determined that a touch-not-button signal has been received (S11 "Yes"), circuit board 40 does not generate any touch control signal (S12).

[0054] When it is determined that no touch non-button signal is received ("No" in S11), the circuit board 40 determines whether a touch button signal is received (S13).

[0055] When it is determined that a touch button signal has been received (S13 "Yes"), the circuit board 40 determines whether a first reference time Δt has elapsed (S14). When it is determined that the first reference time Δt has elapsed (S14 "Yes"), the circuit board 40 determines whether a touch non-button signal has been received within the first reference time Δt (S15).

[0056] When it is determined that no non-button touch signal is received within the first reference time Δt (S15 "No"), that is, when the first condition mentioned above is met, the circuit board 40 determines whether the second reference time T has elapsed. d (S16). When it is determined that the second reference time T has elapsed. d When (S16 "Yes"), the circuit board 40 determines whether it still receives the same touch button signal (S17).

[0057] When it is determined that the same touch button signal is still being received (S17 "Yes"), the circuit board 40 generates a touch control signal based on the received touch button signal (S18).

[0058] When it is determined that no more identical touch button signals are received ("No" in S17), the circuit board 40 does not generate any touch control signals (S12).

[0059] Returning to step S15, when it is determined that a touch non-button signal is received within the first reference time Δt (S15 "Yes"), that is, when the first condition mentioned above is not met, the circuit board 40 does not generate any touch control signal (S12).

[0060] According to an embodiment of the present invention, a method for preventing accidental touch of a button is also provided. The touch button includes a touch film 20, the touch film 20 including button sensing areas 21 spaced apart from each other and non-button sensing areas 22 located around each button sensing area 21.

[0061] A method for preventing accidental touch of a button according to an embodiment of the present invention includes: determining whether the button sensing area 21 is triggered but the button sensing area 22 is not triggered within a first reference time Δt; when it is determined that the button sensing area 21 is triggered but the button sensing area 22 is not triggered within the first reference time Δt, determining that a second reference time T has elapsed. d Whether the same button sensing area 21 is still triggered; when it is determined that the second reference time T has elapsed. d When the same button sensing area 21 is still triggered, the touch button generates a touch control signal corresponding to the button sensing area 21.

[0062] Figure 6 This is a flowchart illustrating a method for preventing accidental operation of vehicle touch buttons according to an embodiment of the present invention. Figure 6 The method for preventing accidental operation of vehicle touch buttons according to an exemplary embodiment of the present invention includes the following steps:

[0063] Determine whether the non-button sensing area 22 is triggered (S21). When it is determined that the non-button sensing area 22 is triggered (S21 "Yes"), the touch button does not generate any touch control signal (S22).

[0064] When it is determined that the non-button sensing area 22 has not been triggered (S21 "No"), determine whether the button sensing area 21 has been triggered (S23).

[0065] When it is determined that the button sensing area 21 is triggered (S23 "Yes"), determine whether the first reference time Δt has elapsed (S24).

[0066] When it is determined that the first reference time Δt has elapsed (S24 "Yes"), it is determined whether the non-button sensing area 22 is triggered within the first reference time Δt (S25).

[0067] When it is determined that the non-button sensing area 22 is triggered within the first reference time Δt (S25 "Yes"), the touch button does not generate any touch control signal (S22).

[0068] When it is determined that the non-button sensing area 22 was not triggered within the first reference time Δt (S25 "No"), that is, it is determined that the button sensing area 21 was triggered and the non-button sensing area 22 was not triggered within the first reference time Δt, then it is determined whether the second reference time T has elapsed. d (S26).

[0069] When it is determined that the second reference time T has elapsed d When (S26 "Yes"), determine whether the same key sensing area 21 is still triggered (S27). When it is determined that the same key sensing area 21 is still triggered (S27 "Yes"), that is, when it is determined that the second reference time T has elapsed. d The same button sensing area 21 is still triggered. At this time, the touch button generates a touch control signal corresponding to the button sensing area 21 (S28).

[0070] When it is determined that the same button sensing area 21 will no longer be triggered (S27 "No"), the touch button does not generate any touch control signal (S22).

[0071] According to an embodiment of the present invention, a touch button for a vehicle and a method for preventing accidental operation of the vehicle touch button are provided. The touch film 20 is improved in hardware. The improved touch film 20 also designates the surrounding area outside each button sensing area 21 as a sensing area (referred to as the non-button sensing area 22). Thus, when a user's finger touches an area outside the button touch area, unlike the prior art where no sensing area is triggered, the non-button sensing area 22 is triggered. This hardware improvement provides a basis for preventing accidental operation of the touch button. Furthermore, the control logic is improved in software. The improved control logic determines whether only the button sensing area 21 is triggered based on a first reference time Δt, and after determining that only the button sensing area 21 is triggered within the first reference time Δt, it further determines whether only the button sensing area 21 is triggered based on a second reference time T. d The system performs a delay detection on the triggered or untriggered state of the previously triggered button sensing area 21, and generates a touch control signal while the button sensing area 21 is still triggered. Therefore, it effectively improves the anti-misoperation capability of vehicle touch buttons.
