Description

Technical Field

[0001] This invention relates to the field of automotive electronics technology, and more particularly to a method, apparatus, electronic device, and storage medium for preventing accidental triggering of touch switches. Background Technology

[0002] Currently, touch switches are widely used in automotive interiors due to their aesthetic appeal, simplicity, and premium feel. Capacitive touch-sensitive switches are the most common type used in automobiles. However, as automotive interior designs evolve, the shapes and materials of touch switches are becoming increasingly complex. Some unusual shapes can affect the sensitivity and interference resistance of touch switches. For example, irregularly shaped touch panels can reduce sensitivity; surrounding metal components such as chrome trim can amplify signals and reduce interference resistance. Furthermore, with the widespread use of electronic devices such as mobile phones, tablets, and walkie-talkies in vehicles, electromagnetic interference is generated when these devices transmit and receive signals. When these devices are close to the touch panel, they may cause accidental triggering of the touch switch. Similarly, passing through areas with strong electromagnetic interference can also lead to accidental switch triggering.

[0003] To address the issue of accidental triggering of the touch switch, a common solution is to improve the situation by adding a touch switch conditioning circuit. However, this method has certain drawbacks: when the touch panel is subjected to interference with a frequency band similar to that of a human finger, the touch switch is prone to accidental triggering.

[0046] It should be understood that the description in this section is not intended to identify key or essential features of the embodiments of the present invention, nor is it intended to limit the scope of the invention. Other features of the invention will become readily apparent from the following description. Attached Figure Description

[0051] Figure 4 This is a schematic diagram of the structure of an electronic device using a method for preventing accidental triggering of a touch switch according to an embodiment of the present invention. Detailed Implementation

[0052] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0053] The touch switch involved in this invention can be a capacitive touch-sensitive switch used in the automotive industry. It works by detecting the presence of a finger near the touch panel through capacitance changes between the touch panel and its environment. A sensor is arranged below the touch panel of the switch. The capacitance of the sensor when the finger is not in contact with the panel surface is called parasitic capacitance (Cp). Parasitic capacitance is generated by the parasitic capacitance inside the sensor and the coupled electric field, the latter being generated by coupling between the sensor board, traces and vias, and other conductors in the system. When a finger touches the panel surface, the finger and the sensor form a simple parallel-plate capacitance (Cf) through the panel. When the capacitance change Cf - Cp reaches a set threshold, the touch chip effectively triggers the switch. Similarly, when electronic devices and other strong electromagnetic interference signals cause the capacitance change to reach the set threshold, the switch will also be triggered.

[0054] Based on the above, this invention improves the hardware structure of the touch switch to avoid accidental triggering of the touch switch due to electromagnetic interference. Specifically, two sensors, a first sensor and a second sensor, are deployed below the touch panel of the touch switch. Both sensors can be capacitive sensors. To accurately deploy the first and second sensors, two preset areas are first set on the touch panel: a first preset area and a second preset area. The first preset area can be a finger-touch area, allowing the user to control the touch switch by touching this area. The second preset area is adjacent to the first preset area and can be an interference signal acquisition area; when the user touches this area, the touch switch cannot be controlled. Furthermore, when deploying the two sensors, the first sensor is deployed below the first preset area to collect trigger signals within that area; the second sensor is deployed below the second preset area to collect trigger signals within that area. To avoid mutual interference between the two sensors, a distance of 2-3 mm is optimal.

[0055] It should be noted that the sensing diameters of fingers and electromagnetic interference are different. The sensing diameter of a finger is about 10mm, while electromagnetic interference covers a large area, far exceeding 10mm. By comparing the output signals of the two sensors using the difference in sensing diameter, fingers and electromagnetic interference can be distinguished. Fingers only generate signals in the touch area, while electromagnetic interference generates signals in both the touch area and the interference signal acquisition area. This allows the source of the signal to be determined, thus improving anti-interference capabilities.

[0056] Furthermore, in addition to the touch panel, the first sensor, and the second sensor, the touch switch also includes a signal processing device and an actuator; wherein, the signal processing device includes a touch chip and a microprocessor, used to compare and process the signals collected by the sensors; the actuator is used to determine whether to turn on the touch switch according to the indication signal output by the signal processing device.

[0057] After introducing the relevant knowledge of the touch switch of the present invention, the specific process of the method to prevent the touch switch from being accidentally triggered can be found in the following embodiments.

[0058] Example 1

[0059] Figure 1 The flowchart of a method for preventing accidental triggering of a touch switch is provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where electromagnetic interference causes the touch switch to be accidentally triggered. The method can be executed by a device for preventing accidental triggering of a touch switch. The device for preventing accidental triggering of a touch switch can be implemented in hardware and / or software and can be configured in an electronic device.

[0060] like Figure 1 As shown, the procedure for preventing accidental triggering of the touch switch is as follows:

[0061] S101. Obtain the first trigger signal within the first preset area collected by the first sensor.

[0062] The first preset area can be a finger-touch area. Since the touch switch of this invention is a capacitive touch-sensitive switch, the first trigger signal collected by the first sensor within the first preset area includes two types: a valid trigger signal and an invalid trigger signal. Specifically, if the first trigger signal includes a signal with parallel plate capacitance (generated by user touch or electromagnetic interference), it is a valid trigger signal; conversely, if the first trigger signal includes a signal with parasitic capacitance (generated without user touch or electromagnetic interference), it is an invalid trigger signal.

[0063] S102, Obtain the second trigger signal within the second preset area collected by the second sensor.

[0064] The second preset area can be selected as an interference signal acquisition area. Since the touch switch of this invention is a capacitive touch-sensitive switch, the second trigger signal acquired by the second sensor within the second preset area includes two types: a valid trigger signal and an invalid trigger signal. Specifically, if the second trigger signal includes a signal with parallel plate capacitance (generated by magnetic interference), it is a valid trigger signal; conversely, if the second trigger signal includes a signal with parasitic capacitance (generated when no one touches the device or there is no electromagnetic interference), it is an invalid trigger signal.

[0065] S103. Determine whether the first trigger signal and the second trigger signal are generated by electromagnetic interference.

[0066] After receiving the first and second trigger signals, the two trigger signals are compared to determine whether they are generated by electromagnetic interference. In one optional embodiment, determining whether the first and second trigger signals are generated by electromagnetic interference includes: determining whether both the first and second trigger signals are valid trigger signals; in another optional embodiment, the first and second trigger signals are converted into digital signals, for example, into signals consisting of high and low levels, and then the presence of a valid trigger signal is determined based on the high and low levels; if so, it is determined that both the first and second trigger signals are generated by electromagnetic interference. If the second trigger signal is invalid trigger information, it is determined that there is no electromagnetic interference at this time. If the first trigger signal is a valid trigger signal, it is determined that the first trigger signal is a genuine touch signal from the user. If both the first and second trigger signals are invalid signals, it is determined that the user has not touched the touch switch, and there is no electromagnetic interference.

[0067] S104. Based on the judgment result, control the touch switch.

[0068] In one alternative implementation, if the second trigger signal is generated by electromagnetic interference, it indicates that there is electromagnetic interference near the touch switch. Therefore, regardless of whether the first trigger signal is a valid signal or an invalid signal, the touch switch is prohibited from being turned on, thereby preventing the touch switch from being accidentally triggered.

[0069] In another alternative implementation, if the second trigger signal is invalid, it means that there is no electromagnetic interference at this time. If the first trigger signal is a real touch signal from the user (i.e., a valid trigger signal), then the touch switch is controlled to turn on. For example, a signal to turn on the switch is sent to the actuator of the touch switch, so that the actuator turns on the touch switch.

[0070] In this embodiment of the invention, as long as the second trigger signal is a valid trigger signal, it is determined that there is electromagnetic interference in the touch switch accessory. At this time, the touch switch is prohibited from being turned on, which can prevent the touch switch from being accidentally triggered. Moreover, the touch switch is only turned on when the first trigger signal is valid and the second trigger signal is invalid, so as to achieve the purpose of accurately identifying the touched signal and improve the anti-interference of the touch switch.

[0071] Example 2

[0072] Figure 2 This is a flowchart illustrating a method for preventing accidental triggering of a touch switch according to Embodiment 2 of the present invention. See also... Figure 2 The method includes the following steps:

[0073] S201. Obtain the first trigger signal within the first preset area collected by the first sensor.

[0074] S202, Obtain the second trigger signal within the second preset area collected by the second sensor.

[0075] The first preset area and the second preset area are two adjacent areas located on the touch panel. Optionally, the first preset area is a finger touch area; the second preset area is an interference signal acquisition area.

[0076] S203. Determine whether the first trigger signal and the second trigger signal are generated by electromagnetic interference.

[0077] In one optional implementation, it is determined whether both the first trigger signal and the second trigger signal are valid trigger signals; if so, it is determined that both the first trigger signal and the second trigger signal are generated by electromagnetic interference. If the first trigger signal is a valid trigger signal and the second trigger signal is invalid trigger information, it is determined that the first trigger signal is a genuine touch signal from the user and there is no electromagnetic interference.

[0078] S204. Reduce the capacitance change threshold of the touch switch.

[0079] By following steps S201-S203, it is determined whether the trigger signal is generated by electromagnetic interference. Based on this determination, the effects of electromagnetic interference on the touch switch can be avoided. In this way, while improving the touch switch's anti-interference capabilities, the capacitance change threshold of the touch switch can also be lowered. According to the principle of touch switches, this operation can improve the sensitivity of the touch switch.

[0080] S205. Based on the judgment result, control the touch switch.

[0081] Optionally, if the second trigger signal is generated by electromagnetic interference, the touch switch is disabled; or, if the first trigger signal is a genuine touch signal from the user and there is no electromagnetic interference, the touch switch is enabled.

[0082] The present invention improves the sensitivity of the touch switch by reducing the capacitance change threshold of the touch switch while ensuring the anti-interference performance of the touch switch.

[0091] The first judgment unit is used to determine whether both the first trigger signal and the second trigger signal are valid trigger signals;
