The chip is used to, upon receiving signals output from the sensing modules in the first touch area and / or the auxiliary area, determine the appropriate sensor based on a first pressure signal and a second pressure signal output from the pressure sensing module in the first touch area. The second pressure signal output by the pressure sensing module in the control area responds to the user's touch operation. If the chip receives signals from the sensing modules in the first touch area and / or the auxiliary area, it indicates that the environment is interfering with the touch switch. For example, in rainy or car wash scenarios, water triggers the capacitive sensing module, and the signal output by the capacitive sensing module is no longer reliable. Therefore, the user's touch operation is responded to based on the pressure signals from the two touch areas. This eliminates the influence of the environment on the touch switch, thereby improving the anti-interference capability of the touch switch. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0039] Touch switches are now widely used in vehicles, including door handles, window switches, and control panels. Traditional touch solutions can be broadly categorized into four types based on their sensing methods: resistive, capacitive, infrared, and ultrasonic. Currently, the vast majority of touch switches utilize capacitive touch technology. Capacitive touch technology further subdivides into self-capacitance and mutual capacitance detection methods. These two methods operate on different principles and have different applications.

[0040] The principle of self-capacitance detection is as follows: Figure 1 As shown, it uses an electrode, and the touch chip measures the capacitance Cx between the electrode and ground. When a finger is placed on the touch switch, the capacitance measured by the touch chip increases. This self-capacitance sensing is best suited for single-point touch sensors, such as buttons.

[0041] The principle of mutual capacitance detection is as follows: Figure 2 As shown, it uses two electrodes, one called the transmitting electrode TX and the other the receiving electrode RX. The touch chip measures the capacitance Cx between the transmitting electrode TX and the receiving electrode RX. Specifically, the touch chip provides a digital voltage (a signal switching between the power supply voltage VDD and ground GND) to the transmitting electrode TX and measures the charge received on the receiving electrode RX. The charge received on the receiving electrode RX is proportional to the capacitance Cx between the two electrodes. When a finger is placed between the transmitting electrode TX and the receiving electrode RX, the capacitance Cx decreases, and the charge received on the receiving electrode RX also decreases, thus reducing the charge measured by the touch chip. This mutual capacitance sensing is best suited for multi-touch systems, such as touchscreens and touchpads.

[0042] However, applying the aforementioned touch switches to automotive exteriors is highly susceptible to environmental influences, often leading to false triggering. Specifically, the following situations may occur:

[0043] 1. Exterior trim and interior components near windows are prone to water droplets or flow. In such situations, capacitive touch controls are prone to malfunctions. For example, door handles, tailgate switches, and window switches are easily triggered in rainy or car-washing conditions.

[0044] 2. Because the detection principle of capacitive touch is to detect the change in dielectric constant of the surrounding environment in a short time by using PAD (pad) to determine whether there is a touch action, false triggering is also likely to occur when objects with low impedance or dielectric constant similar to that of the human body (such as aluminum, iron, etc.) are close to it.

[0045] 3. Because capacitive touch uses common-mode detection and the capacitive detection electrode is similar to an antenna, it is easy to misunderstand power supply ripple and high-frequency noise interference. In particular, the anti-interference effect of radio frequency noise, power line and ground line noise in EMC (Electromagnetic Compatibility) testing is not good.

[0046] 4. For touch switches that unlock by sliding, accidental triggering can easily occur when wiping the touch switch back and forth during manual car washing.

[0047] In addition, there are pressure-sensitive touch switches and pressure-capacitive touch switches. For pressure-sensitive touch switches, when a car goes over a speed bump or vibrates for other reasons, the pressure-sensitive touch switch senses the pressure, resulting in false triggering. For pressure-capacitive touch switches, there is a pressure sensor and a capacitor sensor in the effective touch area. When a lot of water is flushed, it is inevitable that the pressure value and the capacitor will be triggered at the same time, resulting in false triggering.

[0048] Therefore, it is necessary to propose effective technical means to solve the problem that touch switches are easily affected by the environment. The technical solution of this application and how it solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0049] In one embodiment, such as Figure 3 As shown, a schematic diagram of a touch switch is provided. The touch switch includes a touch panel 301 and a chip 302.

[0050] The touch panel includes a first touch area M1, a second touch area M2, and an auxiliary area N; both the first touch area M1 and the second touch area M2 are provided with a pressure sensing module T, or both the first touch area M1 and the second touch area M2 are provided with a capacitive sensing module P and a pressure sensing module T, and the auxiliary area N is provided with a capacitive sensing module P and / or a pressure sensing module T.

[0051] Chip 302 is connected to the sensing modules located in the first touch area M1, the second touch area M2, and the auxiliary area N, respectively.

[0052] When both the first touch area M1 and the second touch area M2 are provided with pressure sensing modules T, the chip 302 is used to respond to the user's touch operation based on the first pressure signal output by the pressure sensing module T in the first touch area M1 and / or the second pressure signal output by the pressure sensing module in the second touch area M2 when it receives the signal output by the sensing module in the first touch area M1 and / or the auxiliary area N.

[0053] When both the first touch area M1 and the second touch area M2 are equipped with a capacitive sensing module P and a pressure sensing module T, the chip 302 is used to respond to the user's touch operation based on the first pressure signal output by the pressure sensing module T in the first touch area M1, the first capacitance signal output by the capacitive sensing module P in the first touch area M1, the second pressure signal output by the pressure sensing module T in the second touch area M2, and the second capacitance signal output by the capacitive sensing module P in the second touch area M2, upon receiving signals output by the sensing modules in the first touch area M1 and / or the auxiliary area N. It should be noted that... Figure 3 Example: Both the first touch area M1 and the second touch area M2 are equipped with only pressure sensing modules T.

[0054] The relative positions of the first touch area M1 and the second touch area M2 can be set according to the button-pressing habits of most people. For example, the distance between the first touch area M1 and the second touch area M2 is less than or equal to 6cm.

[0055] The auxiliary area N is located around the first touch area M1 and the second touch area M2. The auxiliary area N may be provided with at least one capacitive sensing module P, at least one pressure sensing module T, or at least one capacitive sensing module P and at least one pressure sensing module T.

[0056] Optionally, the auxiliary region N includes at least one of a first auxiliary region N1 and a second auxiliary region N2; the first auxiliary region N1 is provided with a pressure sensing module T, and the first auxiliary region N1 is located between the first touch region M1 and the second touch region M2; the second auxiliary region N2 is provided with a capacitive sensing module P, and the second auxiliary region N2 is located in the other areas of the touch panel 301 besides the first touch region M1, the second touch region M2, and the first auxiliary region N1. Preferably, the auxiliary region N includes a first auxiliary region N1 and a second auxiliary region N2. The number of first auxiliary regions N1 can be multiple or one; preferably, one first auxiliary region N1 is provided. The number of second auxiliary regions N2 can be multiple or one; preferably, multiple second auxiliary regions N2 are provided. Figure 3The example uses one first auxiliary area N1 and six second auxiliary areas N2. In this embodiment, the first auxiliary area N1 is set between the first auxiliary area N1 and the second auxiliary areas N2. The first auxiliary area N1 is equipped with a pressure sensing module T, which can prevent accidental triggering caused by wiping the touch switch back and forth in a manual car wash scenario. The second auxiliary area N2 is set, and the second auxiliary area N2 is equipped with a capacitive sensing module P, which can prevent accidental triggering in rainy or car wash scenarios.

[0057] The capacitive sensing module P includes at least one capacitive sensor, which can measure the capacitance between an object (e.g., a finger) and the touch switch, and send a capacitance signal to the chip 302. The pressure sensing module T includes at least one pressure sensor, which can measure the pressure of an object on the touch switch, and send a pressure signal to the chip 302.

[0058] When both the first touch area M1 and the second touch area M2 are provided with a capacitive sensing module P and a pressure sensing module T, the connection of chip 302 with the sensing modules provided in the first touch area M1, the second touch area M2 and the auxiliary area N respectively means that chip 302 is connected to the capacitive sensing module P and the pressure sensing module T provided in the first touch area M1, the capacitive sensing module P and the pressure sensing module T provided in the second touch area M2, and the capacitive sensing module P and / or the pressure sensing module T provided in the auxiliary area N. The connection between the capacitive sensing module P and / or the pressure sensing module T in the auxiliary area N refers to the following: when only the capacitive sensing module P is provided in the auxiliary area N, the chip 302 is connected to the capacitive sensing module P; when only the pressure sensing module T is provided in the auxiliary area N, the chip 302 is connected to the pressure sensing module T; and when only both the capacitive sensing module P and the pressure sensing module T are provided in the auxiliary area N, the chip 302 is connected to both the capacitive sensing module P and the pressure sensing module T. Similarly, when both the first touch area M1 and the second touch area M2 are provided with pressure sensing modules T, it is clear that the chip 302 is connected to the sensing modules in the first touch area M1, the second touch area M2, and the auxiliary area N, respectively, and will not be elaborated further.

[0059] When both the first touch area M1 and the second touch area M2 are provided with pressure sensing modules T, receiving a signal output from the sensing module provided in the first touch area M1 and / or the auxiliary area N means receiving at least one of the following signals: a first pressure signal output by the pressure sensing module T provided in the first touch area M1, a third capacitance signal output by the capacitance sensing module P provided in the auxiliary area N, and a third pressure signal output by the pressure sensing module T provided in the auxiliary area N.

[0060] When a signal is received from the sensing module set in the first touch area M1 and / or the auxiliary area N, it indicates that the environment is interfering with the touch switch. For example, if there is water on the surface of the touch switch, the capacitive sensing module P is triggered. At this time, the chip 302 needs to respond to the user's touch operation based on the first pressure signal output by the pressure sensing module T set in the first touch area M1 and the second pressure signal output by the pressure sensing module T set in the second touch area M2.

[0061] In one possible implementation, for the case where the auxiliary area N includes a first auxiliary area N1 and a second auxiliary area N2, the chip 302 is specifically configured to, upon receiving signals output by the sensing modules of the first touch area M1 and / or the auxiliary area N, further receive a first pressure signal output by the pressure sensing module T of the first touch area M1 and a second pressure signal output by the pressure sensing module T of the second touch area M2. If no third pressure signal is received from the pressure sensing module of the first auxiliary area N1, the chip 302 determines whether both the first and second pressure signals are valid signals. If so, it responds to the user's touch operation. That is, when the auxiliary area N is triggered, the touch switch operates in a dual-touch unlock mode, which is only effective when the user simultaneously touches both the first touch area M1 and the second touch area M2.

[0062] When both the first touch area M1 and the second touch area M2 are provided with a capacitive sensing module P and a pressure sensing module T, receiving a signal output from the sensing module provided in the first touch area M1 and / or the auxiliary area N refers to receiving at least one of the following signals: a first capacitive signal output by the capacitive sensing module P provided in the first touch area M1, a first pressure signal output by the pressure sensing module T provided in the first touch area M1, a third capacitive signal output by the capacitive sensing module P provided in the auxiliary area N, and a third pressure signal output by the pressure sensing module T provided in the auxiliary area N.

[0063] When a signal is received from the sensing module set in the first touch area M1 and / or the auxiliary area N, it indicates that the environment is interfering with the touch switch, such as water on the surface of the touch switch. At this time, the chip 302 needs to respond to the user's touch operation based on the first pressure signal output by the pressure sensing module T set in the first touch area M1, the first capacitance signal output by the capacitance sensing module P set in the first touch area M1, the second pressure signal output by the pressure sensing module T set in the second touch area M2, and the second capacitance signal output by the capacitance sensing module P set in the second touch area M2.

[0064] In one possible implementation, for the case where the auxiliary area N includes a first auxiliary area N1 and a second auxiliary area N2, the chip 302 is specifically configured to, upon receiving a signal output from the sensing module set in the first touch area M1 and / or the auxiliary area N, further receive a first pressure signal output from the pressure sensing module T set in the first touch area M1, a first capacitance signal output from the capacitance sensing module P set in the first touch area M1, a second pressure signal output from the pressure sensing module T set in the second touch area M2, and a second capacitance signal output from the capacitance sensing module P set in the second touch area M2. Furthermore, if no third pressure signal output from the pressure sensing module set in the first auxiliary area N1 is received, the chip 302 determines whether the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal are all valid signals. If so, it responds to the user's touch operation. That is, when the first touch area M1 and / or the auxiliary area N are triggered, the touch switch is in dual-touch unlock mode, which is only effective when the user simultaneously touches both the first touch area M1 and the second touch area M2.

[0065] Responding to the user's touch operation means that chip 302 sends a valid touch signal to the main control board, which then sends the valid touch signal to the vehicle host so that the vehicle host can perform an unlocking operation based on the valid touch signal, such as opening the car door.

[0066] The aforementioned touch switch includes a touch panel 301 and a chip 302. The touch panel includes a first touch area M1, a second touch area M2, and an auxiliary area N. Both the first touch area M1 and the second touch area M2 are provided with a pressure sensing module T, or both the first touch area M1 and the second touch area M2 are provided with a capacitive sensing module P and a pressure sensing module T. The auxiliary area N is provided with a capacitive sensing module P and / or a pressure sensing module T. The chip 302 is connected to the sensing modules provided in the first touch area M1, the second touch area M2, and the auxiliary area N. When both the first touch area M1 and the second touch area M2 are provided with a pressure sensing module T, the chip 302, upon receiving a signal output from the sensing module provided in the first touch area M1 and / or the auxiliary area N, adjusts the sensor position according to the first touch area M1. The first pressure signal output by the pressure sensing module T in the first touch area M1 and the second pressure signal output by the pressure sensing module in the second touch area M2 are used to respond to the user's touch operation. When both the first touch area M1 and the second touch area M2 are equipped with a capacitive sensing module P and a pressure sensing module T, the chip 302 is used to respond to the user's touch operation based on the first pressure signal output by the pressure sensing module T in the first touch area M1, the first capacitive signal output by the capacitive sensing module P in the first touch area M1, the second pressure signal output by the pressure sensing module T in the second touch area M2, and the second capacitive signal output by the capacitive sensing module P in the second touch area M2, when receiving the signal output by the sensing module in the first touch area M1 and / or the auxiliary area N. Regardless of whether a pressure sensing module T is provided in both the first touch area M1 and the second touch area M2, or whether a capacitive sensing module P and a pressure sensing module T are provided in both the first touch area M1 and the second touch area M2, if the chip 302 receives a signal output from the sensing module provided in the auxiliary area N of the first touch area M1, it indicates that the environment is interfering with the touch switch. For example, in a rainy or car wash scenario, water triggers the capacitive sensing module P, and the signal output by the capacitive sensing module P is no longer reliable. Therefore, the user's touch operation is responded to based on the pressure signals of the two touch areas, thus eliminating the influence of the environment on the touch switch and improving the anti-interference capability of the touch switch.

[0067] In an exemplary embodiment, when both the first touch area M1 and the second touch area M2 are provided with pressure sensing modules T, the chip 302 is further configured to respond to the user's touch operation based on the second pressure signal output by the pressure sensing module provided in the second touch area M2 when no signal is received from the sensing modules provided in the first touch area M1 and the auxiliary area N.

[0068] When both the first touch area M1 and the second touch area M2 are provided with a capacitive sensing module P and a pressure sensing module T, the chip 302 is also used to respond to the user's touch operation based on the second capacitance signal output by the capacitive sensing module P and the second pressure signal output by the pressure sensing module T in the second touch area M2, when no signal is received from the sensing modules provided in the first touch area M1 and the auxiliary area N.

[0069] Specifically, when both the first touch area M1 and the second touch area M2 are equipped with pressure sensing modules T, the situation where no signals are received from the sensing modules in the first touch area M1 and the auxiliary area N refers to the situation where no first pressure signal is received from the pressure sensing module T in the first touch area M1, no third capacitance signal is received from the capacitance sensing module P in the auxiliary area N, and no third pressure signal is received from the pressure sensing module T in the auxiliary area N.

[0070] If no signal is received from the sensing modules set in the first touch area M1 and the auxiliary area N, it indicates that the environment does not interfere with the touch switch. For example, the surface of the touch switch is dry and there is no water. At this time, the chip 302 responds to the user's touch operation based on the second pressure signal output by the pressure sensing module T set in the second touch area M2.

[0071] In one possible implementation, chip 302 is specifically used to receive a second pressure signal output by the pressure sensing module T set in the second touch area M2 when no signals are received from the sensing modules set in the first touch area M1 and the auxiliary area N, and to determine whether the second pressure signal is a valid signal. If so, it responds to the user's touch operation. That is, when neither the first touch area M1 nor the auxiliary area N is triggered, the touch switch is in single-touch unlock mode, and it is only effective when the user touches the second touch area M2.

[0072] When both the first touch area M1 and the second touch area M2 are equipped with a capacitive sensing module P and a pressure sensing module T, the situation where no signals are received from the sensing modules in the first touch area M1 and the auxiliary area N refers to the situation where no first capacitive signal is received from the capacitive sensing module P in the first touch area M1, no first pressure signal is received from the pressure sensing module T in the first touch area M1, no third capacitive signal is received from the capacitive sensing module P in the auxiliary area N, and no third pressure signal is received from the pressure sensing module T in the auxiliary area N.

[0073] If no signals are received from the sensing modules set in the first touch area M1 and the auxiliary area N, it indicates that the environment does not interfere with the touch switch. For example, the surface of the touch switch is dry and there is no water. At this time, the chip 302 responds to the user's touch operation based on the second capacitance signal output by the capacitance sensing module P set in the second touch area M2 and the second pressure signal output by the pressure sensing module T set in the second touch area M2.

[0074] In one possible implementation, chip 302 is specifically used to, when not receiving signals from the sensing modules set in the first touch area M1 and the auxiliary area N, receive a second capacitance signal output by the capacitive sensing module P set in the second touch area M2 and a second pressure signal output by the pressure sensing module T set in the second touch area M2, and determine whether both the second capacitance signal and the second pressure signal are valid signals. If so, it responds to the user's touch operation. That is, when neither the first touch area M1 nor the auxiliary area N is triggered, the touch switch is in single-touch unlock mode, and is only effective when the user touches the second touch area M2.

[0075] In this embodiment, the single-touch unlock mode is the more commonly used unlock mode. Therefore, regardless of whether the first touch area M1 and the second touch area M2 are equipped with pressure sensing modules T, or whether the first touch area M1 and the second touch area M2 are equipped with capacitive sensing modules P and pressure sensing modules T, the single-touch unlock mode is maintained when no signal is received from the sensing modules set in the first touch area M1 and the auxiliary area N, that is, when there is no environmental interference to the touch switch. Only when there is environmental interference to the touch switch will it enter the dual-touch unlock mode. This improves the anti-interference capability of the touch switch and also enhances the user experience.

[0076] In one exemplary embodiment, such as Figure 4 The diagram shows a schematic of a touch switch. The touch panel 301 is provided with a first backlight and a second backlight. The first backlight is located in the first touch area M1, and the second backlight is located in the second touch area M2.

[0077] Chip 302 is connected to both a first backlight and a second backlight. Chip 302 is used to control the first touch area M1 to enter a visible prompt state by controlling the first backlight to operate, and to control the first touch area M1 to enter a hidden prompt state by controlling the first backlight to deactivate. Chip 302 can also be used to control the second touch area M2 to enter a visible prompt state by controlling the second backlight to deactivate.

[0078] In this touch panel 201, both the first touch area M1 and the second touch area M2 are etched with patterns, such as logos. When neither the first nor the second backlight is working, the touch panel 301 appears completely black, and the logos on both touch areas M1 and M2 are not visible; that is, both touch areas M1 and M2 are in an invisible state. When the chip 302 controls the first backlight to work, that is, when the chip 302 supplies power to the first backlight, the first backlight emits light, making the logo on the first touch area M1 visible; that is, the first touch area M1 enters a visible state. When the chip 302 controls the second backlight to work, that is, when the chip 302 supplies power to the second backlight, the second backlight emits light, making the logo on the second touch area M2 visible; that is, the second touch area M2 enters a visible state.

[0079] In this embodiment, by setting a first backlight and a second backlight, the chip 302 controls the visibility state of the first touch area M1 and the second touch area M2 by controlling the corresponding backlight, thereby achieving the purpose of prompting the user whether it is dual-touch unlocking or single-touch unlocking.

[0080] In an exemplary embodiment, regardless of whether a pressure sensing module T is provided for both the first touch area M1 and the second touch area M2, or whether a capacitive sensing module P and a pressure sensing module T are provided for both the first touch area M1 and the second touch area M2, the chip 302 is further configured to control both the first touch area M1 and the second touch area M2 to enter a prompt visibility state upon receiving a signal output from the sensing module provided in the first touch area M1 and / or the auxiliary area N.

[0081] Chip 302 is also used to control the second touch area M2 to enter the prompt visible state and control the first touch area M1 to enter the prompt invisible state when no signal is received from the sensor module set in the first touch area M1 and the auxiliary area N.

[0082] In the visible state, the usage prompts corresponding to the touch area are visible, that is, the logo corresponding to the touch area can be seen; in the invisible state, the usage prompts corresponding to the touch area are invisible, that is, the logo corresponding to the touch area cannot be seen.

[0083] In one possible implementation, chip 302 is specifically used to control the first backlight and the second backlight to operate when receiving a signal output from the sensing module set in the first touch area M1 and / or the auxiliary area N, so as to control both the first touch area M1 and the second touch area M2 to enter the prompt visibility state.

[0084] Chip 302 is specifically used to control the second backlight to work and the first backlight to not work when no signal is received from the sensor module set in the first touch area M1 and the auxiliary area N, so as to control the second touch area M2 to enter the prompt visible state and the first touch area M1 to enter the prompt invisible state.

[0085] In this embodiment, the chip 302 controls the visibility state of the first touch area M1 and the second touch area M2 under different conditions, thereby prompting the user whether it is a dual-touch unlock or a single-touch unlock.

[0086] It should be noted that, regardless of whether the chip 302 performs the corresponding action upon receiving a signal from the sensing module set in the first touch area M1 and / or the auxiliary area N, or when it does not receive a signal from the sensing module set in the first touch area M1 and the auxiliary area N, the action is performed after the touch switch is activated. That is, the chip 302 determines whether it has received a signal from the sensing module set in the first touch area M1 and / or the second touch area M2 and / or the auxiliary area N after being activated, i.e., after being activated.

[0087] In an exemplary embodiment, when the auxiliary region N includes a first auxiliary region N1 and a second auxiliary region N2, the chip is configured with different operating logic for different configurations of the first touch region M1 and the second touch region M2, as follows:

[0088] In the case where both the first touch area M1 and the second touch area M2 are equipped with pressure sensing modules T, the chip 302 is specifically used to respond to the user's touch operation based on the first pressure signal and the second pressure signal when it receives the signal output from the sensing module set in the first touch area M1 and / or the auxiliary area N, and if it receives the first pressure signal and the second pressure signal, but does not receive the third pressure signal output from the pressure sensing module set in the first auxiliary area N1.

[0089] In the case where both the first touch area M1 and the second touch area M2 are equipped with a capacitive sensing module P and a pressure sensing module T, the chip 302 is specifically used to respond to the user's touch operation based on the first pressure signal, the first capacitive signal, the second pressure signal and the second capacitive signal when it receives the signal output from the sensing module set in the first touch area M1 and / or the auxiliary area N, and if it receives the first pressure signal, the first capacitive signal, the second pressure signal and the second capacitive signal, but does not receive the third pressure signal output from the pressure sensing module set in the first auxiliary area N1.

[0090] Specifically, chip 302, upon receiving a signal from the sensor module set in the first touch area M1 and / or the auxiliary area N, controls both the first touch area M1 and the second touch area M2 to enter a visible prompt state. At this time, the user can touch the first touch area M1 and the second touch area M2 according to the prompt. When the user touches the first touch area M1 and the second touch area M2, they can do so in a preset order, or the time difference between touching the first touch area M1 and the second touch area M2 can be within a preset time difference.

[0091] If both the first touch area M1 and the second touch area M2 are in the visible state, and the chip 302 receives a third pressure signal in addition to the first and second pressure signals within a preset time difference, it indicates that the touch switch is most likely being wiped at this time, and the touch operation is invalid. The chip 302 will not send a valid touch signal to the main control board, that is, it will not respond to the touch operation. This can avoid false triggering caused by wiping the touch switch back and forth in the scenario of manual car washing, and can also avoid false triggering in the case of heavy rain.

[0092] Therefore, when both the first touch area M1 and the second touch area M2 are equipped with pressure sensing modules T, and both touch areas M1 and M2 are in the visible state, the chip 302 receives the first pressure signal and the second pressure signal within a preset time difference. Only if the third pressure signal is not received will the chip 302 respond to the user's touch operation based on the first pressure signal and the second pressure signal. Similarly, when both the first touch area M1 and the second touch area M2 are equipped with capacitive sensing modules P and pressure sensing modules T, and both touch areas M1 and M2 are in the visible state, the chip 302 receives the first pressure signal, the first capacitive signal, the second pressure signal, and the second capacitive signal within a preset time difference. Only if the third pressure signal is not received will the chip 302 respond to the user's touch operation based on the first pressure signal, the first capacitive signal, the second pressure signal, and the second capacitive signal.

[0093] In an exemplary embodiment, when the auxiliary region N only includes the first auxiliary region N1, the chip is configured with different operating logic for different configurations of the first touch region M1 and the second touch region M2, as follows:

[0094] In the case where both the first touch area M1 and the second touch area M2 are equipped with pressure sensing modules T, the chip 302 is specifically used to respond to the user's touch operation based on the first pressure signal and the second pressure signal when it receives the signal output by the sensing module set in the first touch area M1 and / or the auxiliary area N. If it receives the first pressure signal and the second pressure signal, but does not receive the third pressure signal output by the pressure sensing module T set in the first auxiliary area M1.

[0095] For cases where both the first touch area M1 and the second touch area M2 are equipped with a capacitive sensing module P and a pressure sensing module T, the chip 302 is specifically used to respond to the user's touch operation based on the first pressure signal, the first capacitive signal, the second pressure signal, and the second capacitive signal when it receives the signal output from the sensing module set in the first touch area M1 and / or the auxiliary area N. If it receives the first pressure signal, the first capacitive signal, the second pressure signal, and the second capacitive signal, but does not receive the third pressure signal output from the pressure sensing module T set in the first auxiliary area M1.

[0096] The operating logic of chip 302 in this embodiment is similar to that of chip 302 when the auxiliary region N includes the first auxiliary region N1 and the second auxiliary region N2. Therefore, the specific operating logic of chip 302 in this embodiment can be referred to the specific operating logic of chip when the auxiliary region N includes the first auxiliary region N1 and the second auxiliary region N2, and will not be repeated here.

[0097] In an exemplary embodiment, when the auxiliary region N only includes the second auxiliary region N2, the chip is configured with different operating logic for the different configurations of the first touch region M1 and the second touch region M2, as follows:

[0098] In the case where both the first touch area M1 and the second touch area M2 are equipped with pressure sensing modules T, the chip 302 is specifically used to respond to the user's touch operation based on the first pressure signal and the second pressure signal when it receives the signal output by the sensing module set in the first touch area M1 and / or the auxiliary area N.

[0099] In the case where both the first touch area M1 and the second touch area M2 are equipped with a capacitive sensing module P and a pressure sensing module T, the chip 302 is specifically used to respond to the user's touch operation based on the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal when it receives the signal output from the sensing module set in the first touch area M1 and / or the auxiliary area N.

[0100] When the chip 302 receives a signal from the sensor module set in the first touch area M1 and / or the auxiliary area N, it will control both the first touch area M1 and the second touch area M2 to enter the prompt visibility state. At this time, the user can touch the first touch area M1 and the second touch area M2 according to the prompt.

[0101] If both the first touch area M1 and the second touch area M2 are in the visible state, and the chip 302 receives the signal output from the sensor module in the first touch area M1 and the second touch area M2 within a preset time difference, then regardless of whether the capacitor output from the second auxiliary area N2 is received, it will respond to the user's touch operation based on the signal output from the sensor module in the first touch area M1 and the second touch area M2.

[0102] In an exemplary embodiment, when both the first touch area M1 and the second touch area M2 are provided with pressure sensing modules T, the implementation of responding to the user's touch operation based on the first pressure signal and the second pressure signal can be that the chip 302 is specifically used to determine whether the first pressure signal and the second pressure signal are valid signals. If both the first pressure signal and the second pressure signal are valid signals, then the user's touch operation is responded to.

[0103] When both the first touch area M1 and the second touch area M2 are equipped with a capacitive sensing module P and a pressure sensing module T, the implementation of responding to the user's touch operation based on the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal can be achieved by the chip 302 specifically determining whether the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal are valid signals. If the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal are all valid signals, then the user's touch operation is responded to.

[0104] Specifically, the process by which chip 302 determines whether the first pressure signal is a valid signal includes: chip 302 determining whether the first pressure signal meets the pressure threshold range; if yes, then the first pressure signal is determined to be a valid signal; if no, then the first pressure signal is determined to be an invalid signal.

[0105] The process by which chip 302 determines whether the second pressure signal is a valid signal includes: determining whether the second pressure signal meets the pressure threshold range; if yes, then the second pressure signal is determined to be a valid signal; if no, then the second pressure signal is determined to be an invalid signal.

[0106] The process of chip 302 determining whether the first capacitor signal is a valid signal includes: chip 302 determining whether the first capacitor signal meets the capacitance threshold range; if yes, then the first capacitor signal is determined to be a valid signal; if no, then the first capacitor signal is determined to be an invalid signal.

[0107] The process by which chip 302 determines whether the second capacitor signal is a valid signal includes: chip 302 determining whether the second capacitor signal meets the capacitance threshold range; if yes, then the second capacitor signal is determined to be a valid signal; if no, then the first capacitor signal is determined to be an invalid signal.

[0108] In an exemplary embodiment, when both the first touch area M1 and the second touch area M2 are provided with pressure sensing modules T, the chip 302 is specifically used to receive the pressure signal output by the pressure sensing module T in the first touch area M1 and the pressure signal output by the pressure sensing module T in the second touch area M2 at intervals of a first preset time if both the first pressure signal and the second pressure signal are valid signals. When both the pressure signal output by the pressure sensing module T in the first touch area M1 and the pressure signal output by the pressure sensing module T in the second touch area M2 are valid signals, the chip 302 responds to the user's touch operation.

[0109] Optionally, chip 302 is specifically used to, after determining that both the first pressure signal and the second pressure signal are valid signals, after an interval of a first preset time, again collect the pressure signal from the pressure sensing module T set in the first touch area M1 and the pressure signal from the pressure sensing module T set in the second touch area M2. If both the pressure signal from the pressure sensing module T set in the first touch area M1 and the pressure signal from the pressure sensing module T set in the second touch area M2 meet the pressure threshold range, it indicates that it is a normal touch operation rather than a mis-touch, and then the user's touch operation is responded to. The first preset time can be, for example, 5ms.

[0110] In this embodiment, after determining that both the first pressure signal and the second pressure signal are valid signals, a first preset time interval is elapsed before determining whether the pressure signal corresponding to the first touch area M1 and the pressure signal corresponding to the second touch area M2 are valid, so as to further determine whether the touch switch is accidentally touched. This de-shaking method can filter out interference caused by environmental factors such as car washing and rain.

[0111] When both the first touch area M1 and the second touch area M2 are equipped with a capacitive sensing module P and a pressure sensing module T, the chip 302 is specifically used to receive, at a first preset time interval, the pressure signal output by the pressure sensing module T in the first touch area M1, the capacitance signal output by the capacitive sensing module P in the first touch area M1, the pressure signal output by the pressure sensing module T in the second touch area M2, and the capacitance signal output by the capacitive sensing module P in the second touch area M2, provided that all three signals are valid. The chip 302 then responds to the user's touch operation.

[0112] Optionally, chip 302 is specifically used to, after determining that the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal are all valid signals, after an interval of a first preset time period, to again collect the pressure signal output by the pressure sensing module T set in the first touch area M1, the capacitance signal output by the capacitance sensing module P set in the first touch area M1, the pressure signal output by the pressure sensing module T set in the second touch area M2, and the capacitance signal output by the capacitance sensing module P set in the second touch area M2. If the pressure signal of the pressure sensing module T set in the first touch area M1 meets the pressure threshold range, the capacitance signal output by the capacitance sensing module P set in the first touch area M1 meets the capacitance threshold range, the pressure signal of the pressure sensing module T set in the second touch area M2 meets the pressure threshold range, and the capacitance signal output by the capacitance sensing module P set in the second touch area M2 meets the capacitance threshold range, it indicates that it is a normal touch operation rather than a mis-touch, and then responds to the user's touch operation.

[0113] In this embodiment, after determining that the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal are all valid signals, after an interval of a first preset time, it is determined whether the pressure signal and capacitance signal corresponding to the first touch area M1 and the pressure signal and capacitance signal corresponding to the second touch area M2 are valid, so as to further determine whether the touch switch is accidentally touched. This de-shaking method can filter out interference caused by environmental factors such as car washing and rain.

[0114] In an exemplary embodiment, when both the first touch area M1 and the second touch area M2 are provided with pressure sensing modules T, the chip 302 is further configured to determine, within a second preset time period before determining whether the first pressure signal and the second pressure signal are valid signals, whether the pressure signal output by the pressure sensing module T provided in the first touch area M1 and the pressure signal output by the pressure sensing module T provided in the second touch area M2 are received; if not, the step of determining whether the first pressure signal and the second pressure signal are valid signals is executed.

[0115] For specific application scenarios of touch switches, such as car door locks, it is unlikely that there will be continuous door opening operations within 3 seconds. Therefore, after receiving the first pressure signal and the second pressure signal, chip 302 does not immediately perform the step of determining whether the first pressure signal and the second pressure signal are valid signals. Instead, it first determines whether, within a second preset time period before determining whether the first pressure signal and the second pressure signal are valid signals, it has received the pressure signal output by the pressure sensing module T set in the first touch area M1 and the pressure sensing module T set in the second touch area M2. If yes, then there is no need to perform the step of determining whether the first pressure signal and the second pressure signal are valid signals; if no, then the step of determining whether the first pressure signal and the second pressure signal are valid signals is performed. The second preset time period can be, for example, 3 seconds.

[0116] In this embodiment, by determining whether the pressure signal output by the pressure sensing module T set in the first touch area M1 and the pressure signal output by the pressure sensing module T set in the second touch area M2 are received within the second preset time period, it is determined whether the first pressure signal and the second pressure signal are continuously input signals. If so, no processing is performed, which further improves the anti-interference capability of the touch switch.

[0117] When both the first touch area M1 and the second touch area M2 are provided with a capacitive sensing module P and a pressure sensing module T, the chip 302 is further configured to determine, within a second preset time period before determining whether the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal are valid signals, whether the pressure signal output by the pressure sensing module T in the first touch area M1, the capacitance signal output by the capacitive sensing module P in the first touch area M1, the pressure signal output by the pressure sensing module T in the second touch area M2, and the capacitance signal output by the capacitive sensing module P in the second touch area M2 are received. If not, the step of determining whether the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal are valid signals is executed.

[0118] For specific application scenarios of touch switches, such as car door locks, it is unlikely that there will be continuous door opening operations within 3 seconds. Therefore, after receiving the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal, the chip 302 does not immediately perform the step of determining whether the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal are valid signals. Instead, it first determines whether, within a second preset time period before determining whether the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal are valid, the pressure signal output by the pressure sensing module T set in the first touch area M1, the capacitance signal output by the capacitance sensing module P set in the first touch area M1, the pressure signal output by the pressure sensing module T set in the second touch area M2, and the capacitance signal output by the capacitance sensing module P set in the second touch area M2 are received. If yes, then there is no need to perform the step of determining whether the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal are valid signals; if no, then the step of determining whether the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal are valid signals is performed. The second preset time period can be, for example, 3 seconds.

[0119] In this embodiment, by determining whether the pressure signal output by the pressure sensing module T set in the first touch area M1, the capacitance signal output by the capacitance sensing module P set in the first touch area M1, the pressure signal output by the pressure sensing module T set in the second touch area M2, and the capacitance signal output by the capacitance sensing module P set in the second touch area M2 are received within a second preset time period, it is determined whether the first pressure signal, the first capacitance signal, the second pressure signal, and the second capacitance signal are continuously input signals. If so, no processing is performed, further improving the anti-interference capability of the touch switch.

[0120] In an exemplary embodiment, when both the first touch area M1 and the second touch area M2 are provided with pressure sensing modules T, the chip 302 is specifically used to respond to the user's touch operation based on the second pressure signal if a second pressure signal is received and no signal is received from the sensing modules provided in the first touch area M1 and the auxiliary area N.

[0121] When both the first touch area M1 and the second touch area M2 are provided with a capacitive sensing module P and a pressure sensing module T, the chip 302 is specifically used to respond to the user's touch operation based on the second capacitive signal and the second pressure signal if it receives a second capacitive signal and a second pressure signal when it does not receive a signal output from the sensing modules provided in the first touch area M1 and the auxiliary area N, and does not receive a signal output from the sensing modules provided in the first touch area M1 and the auxiliary area N.

[0122] Specifically, chip 302 is used to control the second touch area M2 to enter the prompt visible state and the first touch area M1 to enter the prompt invisible state when no signal is received from the sensor module set in the first touch area M1 and the auxiliary area N. At this time, the user can touch the second touch area M2 according to the prompt.

[0123] When both the first touch area M1 and the second touch area M2 are equipped with pressure sensing modules T, if the second touch area M2 enters the visible state and the first touch area M1 enters the invisible state, the chip 302 receives signals from other areas in addition to the second pressure signal. This indicates that the touch switch is likely to be accidentally touched, the touch operation is invalid, and the chip 302 will not send a valid touch signal to the main control board, that is, it will not respond to the touch operation.

[0124] Therefore, when the second touch area M2 is in the visible state and the first touch area M1 is in the invisible state, the chip 302 will only respond to the user's touch operation based on the second pressure signal when it receives the second pressure signal.

[0125] In the case where both the first touch area M1 and the second touch area M2 are equipped with a capacitive sensing module P and a pressure sensing module T, if the second touch area M2 enters the visible state and the first touch area M1 enters the invisible state, the chip 302 receives signals from other areas in addition to the second capacitive signal and the second pressure signal. This indicates that the touch switch is likely to be accidentally touched, and the touch operation is invalid. The chip 302 will not send a valid touch signal to the main control board, that is, it will not respond to the touch operation.

[0126] Therefore, when the second touch area M2 is in the visible state and the first touch area M1 is in the invisible state, the chip 302 will only respond to the user's touch operation based on the second capacitance signal and the second pressure signal when it receives the second capacitance signal and the second pressure signal.

[0127] Optionally, when both the first touch area M1 and the second touch area M2 are provided with pressure sensing modules T, the implementation of responding to the user's touch operation based on the second pressure signal can be achieved by chip 302, which is specifically used to determine whether the second pressure signal is a valid signal. If the second pressure signal is a valid signal, then the user's touch operation is responded to.

[0128] When both the first touch area M1 and the second touch area M2 are equipped with a capacitive sensing module P and a pressure sensing module T, the implementation of responding to the user's touch operation based on the second capacitance signal and the second pressure signal can be achieved by chip 302, which is specifically used to determine whether the second capacitance signal and the second pressure signal are valid signals. If both the second capacitance signal and the second pressure signal are valid signals, then the user's touch operation is responded to.

[0129] Specifically, the process by which chip 302 determines whether the second capacitor signal is a valid signal includes: chip 302 determining whether the second capacitor signal meets the capacitance threshold range; if yes, then the second capacitor signal is determined to be a valid signal; if no, then the second capacitor signal is determined to be an invalid signal.

[0130] The process by which chip 302 determines whether the second pressure signal is a valid signal includes: determining whether the second pressure signal meets the pressure threshold range; if yes, then the second pressure signal is determined to be a valid signal; if no, then the second pressure signal is determined to be an invalid signal.

[0131] In an exemplary embodiment, when both the first touch area M1 and the second touch area M2 are provided with pressure sensing modules T, the chip 302 is specifically used to receive the pressure signal output by the pressure sensing module T in the second touch area M2 at a third preset time interval if the second pressure signal is a valid signal, and to respond to the user's touch operation when the pressure signal output by the pressure sensing module T in the second touch area M2 is a valid signal.

[0132] Optionally, after determining that all the second pressure signals are valid, chip 302 is used to collect the pressure signal output by the pressure sensing module T set in the second touch area M2 again after a third preset time interval. If the pressure signal of the pressure sensing module P set in the second touch area M2 meets the pressure threshold range, it indicates that it is a normal touch operation rather than a mis-touch, and then the chip 302 responds to the user's touch operation. The third preset time interval can be, for example, 5ms.

[0133] In this embodiment, after determining that all the second pressure signals are valid signals, a third preset time interval is elapsed before determining whether the pressure signal output by the pressure sensing module T in the second touch area M2 is valid, so as to further determine whether the touch switch is accidentally touched. This debouncing method further improves the anti-interference capability of the touch switch.

[0134] When both the first touch area M1 and the second touch area M2 are equipped with a capacitive sensing module P and a pressure sensing module T, the chip 302 is specifically used to receive the capacitive signal and pressure signal output by the capacitive sensing module P and the pressure sensing module T respectively in the second touch area M2 at a third preset time interval if both the second capacitive signal and the second pressure signal are valid signals. When both the capacitive signal and the pressure signal output by the capacitive sensing module P and the pressure sensing module T are valid signals, the chip 302 responds to the user's touch operation.

[0135] Optionally, after determining that both the second capacitance signal and the second pressure signal are valid signals, the chip 302 is used to collect the capacitance signal and pressure signal output by the capacitance sensing module P and the pressure sensing module T set in the second touch area M2 again after a third preset time interval. If the capacitance signal of the capacitance sensing module P set in the second touch area M2 meets the capacitance threshold range, and the pressure signal of the pressure sensing module P set in the second touch area M2 meets the pressure threshold range, it indicates that it is a normal touch operation rather than a mis-touch, and then the chip 302 responds to the user's touch operation.

[0136] In this embodiment, after determining that both the second capacitance signal and the second pressure signal are valid signals, a third preset time interval is elapsed before determining whether the capacitance signal and pressure signal output by the capacitance sensing module P and the pressure sensing module T set in the second touch area M2 are valid, so as to further determine whether the touch switch is accidentally touched. This debouncing method further improves the anti-interference capability of the touch switch.

[0137] In an exemplary embodiment, when both the first touch area M1 and the second touch area M2 are provided with pressure sensing modules T, the chip is further configured to determine whether a pressure signal output by the pressure sensing module T provided in the second touch area M2 is received within a fourth preset time period before determining whether the second pressure signal is a valid signal. If not, the chip performs the step of determining whether the second pressure signal is a valid signal.

[0138] For specific application scenarios of touch switches, such as car door locks, it is unlikely that there will be continuous door opening operations within 3 seconds. Therefore, after receiving the second pressure signal, chip 302 does not immediately perform the step of determining whether the second pressure signal is a valid signal. Instead, it first determines whether a pressure signal output by the pressure sensing module T set in the second touch area M2 has been received within a fourth preset time period before determining whether the second pressure signal is a valid signal. If yes, then there is no need to perform the step of determining whether the second pressure signal is a valid signal; if no, then the step of determining whether the second pressure signal is a valid signal is performed. The fourth preset time period can be, for example, 3 seconds.

[0139] In this embodiment, the second pressure signal is determined to be a continuously input signal by judging whether the pressure signal output by the pressure sensing module T set in the second touch area M2 is received within the fourth preset time period. If so, no processing is performed, which further improves the anti-interference capability of the touch switch.

[0140] When both the first touch area M1 and the second touch area M2 are provided with a capacitive sensing module P and a pressure sensing module T, the chip 302 is also used to determine whether the capacitive signal and the pressure signal output by the capacitive sensing module P and the pressure sensing module T respectively in the second touch area M2 are received within a fourth preset time period before determining whether the second capacitive signal and the second pressure signal are valid signals. If not, the step of determining whether the second capacitive signal and the second pressure signal are valid signals is executed.

[0141] For specific application scenarios of touch switches, such as car door locks, it is unlikely that there will be continuous door opening operations within 3 seconds. Therefore, after receiving the second capacitance signal and the second pressure signal, the chip 302 does not immediately perform the step of determining whether the second capacitance signal and the second pressure signal are valid signals. Instead, it first determines whether, within a fourth preset time period before determining whether the second capacitance signal and the second pressure signal are valid signals, it has received the capacitance signal and the pressure signal output by the capacitance sensing module P and the pressure sensing module T set in the second touch area M2, respectively. If yes, then there is no need to perform the step of determining whether the second capacitance signal and the second pressure signal are valid signals; if no, then the step of determining whether the second capacitance signal and the second pressure signal are valid signals is performed.

[0142] In this embodiment, by determining whether the capacitance signal and pressure signal output by the capacitance sensing module P and pressure sensing module T set in the second touch area M2 are received within a fourth preset time period, it is determined whether the second capacitance signal and the second pressure signal are continuously input signals. If so, no processing is performed, which further improves the anti-interference capability of the touch switch.

[0143] In summary, to further clarify the logic of the touch switch, the following table is used to illustrate the concept. Tables 1 and 2 are for the case where the auxiliary area N includes both the first auxiliary area N1 and the second auxiliary area N2; Tables 3 and 4 are for the case where the auxiliary area N includes only the first auxiliary area N1; and Tables 5 and 6 are for the case where the auxiliary area N includes only the second auxiliary area N2. Specifically, Tables 1, 3, and 5 are for the case where only the pressure sensing module T is provided in the first touch area M1 and the second touch area M2, while Tables 2, 4, and 6 are for the case where both the capacitive sensing module P and the pressure sensing module T are provided in the first touch area M1 and the second touch area M2.

[0157] In one exemplary embodiment, the touch switch further includes a plurality of first resistors and / or a plurality of second resistors; when the touch switch includes only a plurality of first resistors, the plurality of first resistors are disposed between the chip 302 and the sensing module in the first touch area M1, and / or, the plurality of first resistors are disposed between the chip 302 and the sensing module in the second touch area M2; when the touch switch includes only a plurality of second resistors, the plurality of second resistors are disposed between the chip 302 and the sensing module in the auxiliary area N; when the touch switch includes a plurality of first resistors and a plurality of second resistors, the plurality of first resistors are disposed between the chip 302 and the sensing module in the first touch area M1, and / or, the plurality of first resistors are disposed between the chip 302 and the sensing module in the second touch area M2; the plurality of second resistors are disposed between the chip 302 and the sensing module in the auxiliary area N.

[0158] Preferably, the touch switch includes a plurality of first resistors and a plurality of second resistors. The plurality of first resistors are disposed between the chip 302 and the sensing module in the first touch area M1, and the plurality of first resistors are disposed between the chip 302 and the sensing module in the second touch area M2; the plurality of second resistors are disposed between the chip 302 and the sensing module in the auxiliary area N.

[0159] The touch panel also includes a substrate, and the sensing modules in the first touch area M1, the second touch area M2, and the auxiliary area N are all disposed on one side of the substrate; a ground layer with a grid structure is disposed between the substrate and the sensing modules in the first touch area M1, and / or, a ground layer with a grid structure is disposed between the substrate and the sensing modules in the second touch area M2, and / or, a ground layer with a grid structure is disposed between the substrate and the sensing modules in the auxiliary area N.

[0160] Preferably, a ground layer with a grid structure is provided between the substrate and the sensing module in the first touch area M1, a ground layer with a grid structure is provided between the substrate and the sensing module in the second touch area M2, and a ground layer with a grid structure is provided between the substrate and the sensing module in the auxiliary area N.

[0161] A grounding layer with a mesh structure is disposed around the outside of the sensing module in the first touch area M1, and / or, a grounding layer with a mesh structure is disposed around the outside of the sensing module in the second touch area M2, and / or, a grounding layer with a mesh structure is disposed around the outside of the sensing module in the auxiliary area N.

[0162] Preferably, a grounding layer with a grid structure is arranged around the outside of the sensing module in the first touch area M1, a grounding layer with a grid structure is arranged around the outside of the sensing module in the second touch area M2, and a grounding layer with a grid structure is arranged around the outside of the sensing module in the auxiliary area N.

[0163] Optional, such as Figure 5 The diagram illustrates a touch switch, exemplified by chip 302 and the capacitive sensing module P in the second touch area M2. Pin 1 of chip 302 is connected to the capacitive sensing module P via a series resistor R, which is positioned close to pin 1 of the chip. The connection line between chip 302 and the capacitive sensing module P is shorter than a predetermined length.

[0164] The bottom layer of the PCB board beneath the capacitive sensing module P has a ground layer with a mesh structure, such as... Figure 5 The medium gray grid lines are used, while solid ground planes are used for other circuit sections away from the capacitive sensing module P and the traces.

[0165] The capacitive sensing module P is surrounded by a ground layer with a grid structure, such as Figure 5 The grid lines are relatively thick and black. The ground layer of the grid structure surrounding the capacitive sensing module P can be either closed or open. Figure 5 A closed-ended example.

[0166] In this embodiment, the above-mentioned touch switch has the following advantages:

[0167] 1) Reducing the length of the connection line between chip 302 and capacitive sensing module P can reduce noise interference and improve the signal-to-noise ratio.

[0168] 2) A series resistor is set between chip 302 and capacitive sensing module P to form a low-pass RC (Resistor-Capacitance) filter, thereby reducing the amplitude of RF noise coupled to chip 302; in addition, the series resistor R is set close to the pin of chip 302, which can filter out the radiated noise caused by the trace at the input of chip 302.

[0169] 3) A grid-structured ground plane is set on the bottom layer of the PCB board below the capacitive sensing module P, and a grid-structured ground plane is also set around the capacitive sensing module P. Meanwhile, solid ground planes are used for other circuit sections away from the capacitive sensing module P and its traces. This reduces RF radiation and interference, thereby minimizing noise interference to the capacitive signal. Furthermore, setting the trace size to 8mil can further reduce noise interference to the capacitive signal.

[0170] In one embodiment, such as Figure 6 As shown in the diagram, this application also provides a schematic diagram of a switch module, which includes a main control board, a linear motor, and a touch switch as described in any of the above-mentioned touch switch embodiments; the main control board is connected to the linear motor and the touch switch respectively; the touch switch sends a valid touch signal to the main control board to respond to the user's touch operation; the main control board controls the linear motor to vibrate based on the valid touch signal.

[0171] Optionally, the switch module may also include an LED module, a LIN (Local Interconnect Network) communication interface, and a linear interface.

[0172] Among them, the main control board is the data processing center; the linear motor provides vibration feedback; the LED module provides lighting feedback; the LIN communication interface is a software interface, which is the information exchange interface between the switch module and the vehicle host; and the linear interface is a hardware interface, which is the interface for the switch module to exchange switching signals with the vehicle host.

[0173] The working principle of this switch module is as follows:

[0174] 1) When a finger touches the touch switch, the main control board receives the valid touch signal sent by the touch switch, controls the linear motor to vibrate, controls the LED module to output the corresponding light indicator, and sends a LIN command to the vehicle host to notify the vehicle host that a button has been pressed.

[0175] 2) The vehicle host sends a sleep command through the LIN communication interface. After receiving the sleep command, the main control board turns off the LED module, disables the linear motor function and the touch switch function, and all pins of the main control board enter low power mode.

[0176] 3) The vehicle host sends a wake-up command through the LIN communication interface. After the main control board receives the wake-up command, the LED module lights up, enabling the linear motor function and the touch switch function. All pins of the main control board enter the working mode.
