[0037] The implementation principle of a car window lift switch circuit in an embodiment of the present application is as follows: after the user presses the button SW, one of the ROW lines will be connected to a COL line, and a high-level ROW signal and COL signal will be output to the chip U1 under the power supply of the 3V end. The chip U1 calculates and determines which button SW is pressed, thereby executing the corresponding action and outputting a signal of the corresponding waveform through the RXD signal and the TXD signal to control the lifting and lowering of the car window.

[0038] Example 1 of the present application discloses a control method for a car window lift switch. Figure 5 , the control method of the automobile window lifting switch includes the following steps: S1. Get ROW signal and COL signal; S11, determine the trigger button data through the ROW signal and the COL signal; S12. Determine and output a control signal based on the trigger button data and a preset control threshold.

[0039] In detail: Chip U1 determines whether the ROW signal and COL signal are connected and received through the high and low levels of the corresponding pins. Assuming that the ROW0 signal is high, the ROW1 signal is low, the COL0 signal is high, and the COL1 signal is low, it means that the ROW0 signal and the COL0 signal are in a high-level conductive state. At this time, the trigger button data is (ROW0 signal, COL0 signal). Assuming the control threshold is (ROW0 signal, COL0 signal, A), (ROW0 signal, COL1 signal, B), it means that action A is executed when the ROW0 signal and the COL0 signal are in a high-level conductive state, and action B is executed when the ROW0 signal and the COL1 signal are in a high-level conductive state. At this time, the trigger button data is (ROW0 signal, COL0 signal), thereby outputting a control signal for executing action A. In this embodiment, the trigger button data is to obtain the control signal by looking up the table within the control threshold. In other embodiments, the control signal can also be obtained by other methods, such as a relational expression.

[0040] Example 1 of the present application discloses a computer-readable storage medium. Figure 1The computer-readable storage medium stores a computer program that can be loaded and executed by a processor to control a method for controlling a vehicle window lift switch.

[0041] Computer-readable storage media include, for example, various media that can store program codes, such as a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disk.

[0042] Example 2: Different from the embodiment 1, the embodiment 2 of the present application discloses a control method for a car window lifting switch. Figure 2 and Figure 6 The control method of the automobile window lift switch further includes the following steps: S2. Obtain timing data, and determine a judgment signal based on the timing data, a preset misjudgment time threshold, multiple ROW signals, and multiple COL signals; S21, determining the test waveform data by judging the signal and the preset test threshold and outputting it; S22, repeatedly obtain the ROW signal and the COL signal; S23, determining row variable data and column variable data by testing waveform data, timing data, multiple ROW signals, and multiple COL signals; S24, determining group data based on the timing data, the row variable data, and the column variable data; S25 , determining a plurality of trigger button data according to the group data, a plurality of ROW signals, and a plurality of COL signals.

[0043] Detailed: Assume that the false positive time threshold is 0.01s, and each received ROW signal or COL signal will record the receiving time. For example, if the ROW1 signal is high and the timing data is 1min0.1s, it means that the high-level ROW1 signal is received at 0.1 seconds of the first minute. If the difference between the timing data corresponding to multiple adjacent ROW signals and COL signals is less than the false positive time threshold, for example, when the timing data is 1min0.1s and 1min0.During the 11s period, if the ROW0 signal, ROW1 signal, COL0 signal and COL1 signal are received at a high level, it means that multiple ROW signals or COL signals are received at the same time. At this time, a problem will arise. For ease of understanding, for example, if the button SW13 and the button SW10 are pressed at the same time, the ROW0 signal, ROW1 signal, COL0 signal and COL1 signal will all be at a high level. If the button SW11 and the button SW12 are pressed at the same time, the ROW0 signal, ROW1 signal, COL0 signal and COL1 signal will also be at a high level. Even if the buttons SW13, SW10, SW11 and SW12 are pressed at the same time, the ROW0 signal, ROW1 signal, COL0 signal and COL1 signal will be at a high level. Pressing will also make the ROW0 signal, ROW1 signal, COL0 signal and COL1 signal at a high level. If there is a sequence, it is easy to judge, and the false judgment time threshold is used to judge whether they are received at the same time. At this time, it is limited by the calculation frequency of the chip U1, and it will be impossible to calculate which button SW is pressed. Therefore, step S21 is entered, and the test threshold is a sequential combination test. If the judgment signal is that the ROW0 signal, ROW1 signal, COL0 signal and COL1 signal are at a high level, then according to the test threshold, it is necessary to first actively reduce the chip U1 pin corresponding to the ROW0 signal and the COL0 signal to a low level, and then restore it, and then the ROW0 signal and the COL1 signal are at a high level. The corresponding chip U1 pin is actively reduced to a low level and then restored. Then the chip U1 pin corresponding to the ROW1 signal and the COL0 signal is actively reduced to a low level and then restored. Then the chip U1 pin corresponding to the ROW1 signal and the COL1 signal is actively reduced to a low level. This process is the test waveform data. The waveform here refers to the high and low level changes of the pin of the chip U1. During this change process, the ROW signal and the COL signal of other pins are repeatedly obtained. Since the ROW signal and the COL signal obtained at this time only retain a high level, accurate trigger button data can be obtained. For example, when the chip U1 pin corresponding to the ROW0 signal and the COL0 signal is actively reduced to a low level, If both the ROW1 and COL1 signals remain high, the group data is (ROW1 signal, COL1 signal), indicating that key SW10 has been pressed. The change in the ROW1 signal is the row variable data, and the change in the COL1 signal is the column variable data. If the ROW1 signal remains high but the COL0 signal changes to a low level, it means that SW12, not SW10, has been pressed. However, since the ROW0 signal is forced to a low level, the COL1 signal is pulled down to a low level. The group data is now (ROW0 signal and COL1 signal). By changing in this order, accurate trigger key data can be obtained while eliminating interference from simultaneous triggering.

[0044] Reference Figure 2 and Figure 7, further comprising the following steps: S3. Determine the current glass state data through all control signals; S31, determining triggering all possible data through multiple ROW signals and multiple COL signals; S32, determining the priority data for changing the state through the current glass state data and the trigger all possible data; S33, determining priority test data by changing the state priority data and the test threshold; S34, replacing the test threshold with the priority test data to determine the test waveform data with the judgment signal and output it; S35. After calculating and determining the trigger button data, determine the troubleshooting data by triggering all possible data and the change state priority data. The troubleshooting data has a lower priority than the judgment signal and the trigger button data. S36. Determine the troubleshooting test data based on the troubleshooting data and the test threshold; S37. The test waveform data is determined and outputted by checking the test data instead of the test threshold value with the judgment signal to obtain the remaining trigger button data.

[0045] In detail: each time a control signal is output, it is recorded, and then the current state of the car glass can be obtained, such as closed, fully open, half open, etc., which is the glass state data. Before entering step S21, step S31 is entered first. At this time, all possible possibilities of triggering buttons SW are calculated by all ROW signals and COL signals triggered simultaneously. For example, if ROW0 signal, ROW1 signal, COL0 signal and COL1 signal are at a high level, then all possibilities include buttons SW13, SW12, SW11 and SW10 being pressed and triggered, which is the triggering of all possible data. Combined with the state of the car glass at this time, for example, button SW13 is for the main driver's car glass to rise, button SW12 is for the co-driver's car glass to rise, button SW11 is for the main driver's car glass to fall, and button SW10 is for the co-driver's car glass to fall, if the current state data of the glass is that the main driver's car glass is closed and the co-driver's car glass is fully open, then the main driver's car glass is falling at this time. It will change the current state of the main driver's car glass. The rising of the co-driver's car glass will change the current state of the co-driver's car glass, that is, buttons SW12 and SW11 will change the current glass state, which is the priority data for changing the state, and then combined with the test threshold, give priority to testing whether buttons SW12 and SW11 are pressed, that is, the original sequential test, at this time, the ROW1 signal and the COL0 signal will be changed to a low level to test the button SW12, and the ROW0 signal and the COL1 signal will be changed to a low level to test the button SW11, which is the test waveform data. If buttons SW12 and SW11 are indeed pressed and triggered, the corresponding trigger button data is obtained for output control, and the troubleshooting data is obtained. The remaining previously untested items are tested again in sequence through the troubleshooting data and the test threshold. If a new button signal is received when the troubleshooting data is being checked and calculated, the new button signal will be processed first, and then the calculation of the troubleshooting data will continue. If the chip U1 used can be processed in parallel, it will be processed simultaneously.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
