[0024] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.
[0025] The control method, device, controller, vehicle and storage medium of the touch screen in the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0026] In some embodiments, the touch screen of the in-vehicle terminal can be a capacitive touch screen, a resistive touch screen, an infrared touch screen, etc., and the touch screen includes at least one function button. In the following description, it is taken as an example that the touch screen of the in-vehicle terminal is a capacitive touch screen and the touch screen includes two function buttons, but it is not a limitation to the present application.
[0027] Figure 1 Flow chart of the control method for a touch screen according to some embodiments of the present application. Refer to Figure 1 , the control method of the touch screen in the embodiments of the present application may include the following steps:
[0028] S110, in response to the touch signal, determine the center position of the contact point according to the touch signal.
[0029] Specifically, the user can send a touch signal by clicking on the touch screen. The electrode array of the touch screen detects the capacitance change and converts it into an electrical signal, and transmits the electrical signal to the ECU (Electronic Control Unit) for processing to determine the center position of the contact point. For example, the center position of the contact point is calculated according to the capacitance change value by using linear interpolation or the least squares method.
[0030] S120, determine the distance between the center position of the contact point and the center position of each function button.
[0031] Specifically, assume that the function keys of the touch screen include function key 1 and function key 2. After determining the center position of the contact point, the ECU calculates the distances between the center positions of function key 1 and function key 2 and the center position of the contact point respectively.
[0032] S130. Determine the number of consecutive touch failures within a preset time based on the distances, and record multiple corresponding center positions of the contact points. The preset time can be determined according to the actual situation. For example, the preset time can be 3s, and no specific limitation is made here.
[0033] Specifically, it can be determined whether the user's touch is effective according to the distance between the center position of the contact point and the center position of the function key, and the target function key touched by the user can be determined in the case of an effective touch. For example, if the distance between the center position of the contact point and the center position of function key 1 is relatively small, it is determined that the touch is effective, and the target function key is determined to be function key 1; if the distance between the center position of the contact point and the center position of function key 2 is relatively small, it is determined that the touch is effective, and the target function key is determined to be function key 2; if the distances between the center position of the contact point and the center positions of both function key 1 and function key 2 are relatively large, it is determined that the touch fails.
[0034] After determining that the touch fails, it is also necessary to further determine whether it is a mis-touch by the user. Therefore, start timing after determining that the touch fails. The touch screen continuously responds to the touch signal within the preset time to determine the center position of the contact point, and determine the distance between the center position of the contact point and the center position of the function key, determine whether the touch fails according to the distance, and record the number of consecutive touch failures within the preset time. Determine whether it is a mis-touch by the user according to the number of consecutive touch failures within the preset time. For example, if the number of consecutive touch failures within the preset time is relatively small, it is determined that the user mis-touches; if the number of consecutive touch failures within the preset time is relatively large, it is determined that the user actually has the need to click the function key.
[0035] In the case of determining that it is not a mis-touch by the user, it is also necessary to record multiple corresponding center positions of the contact points. For example, in the case of determining that the number of consecutive touch failures is 3, 3 center positions of the contact points will be recorded.
[0036] S140. In the case where the number of consecutive touch failures is greater than or equal to the preset threshold of the number of consecutive touch failures, determine the target function key according to multiple center positions of the contact points and the center positions of the function keys. The preset threshold of the number of consecutive touch failures can be determined according to the actual situation. For example, the preset threshold of the number of consecutive touch failures can be 3, and no specific limitation is made here.
[0037] Specifically, it is possible to determine whether it is a user's accidental touch by comparing the number of consecutive touch failures with a preset threshold of the number of consecutive touch failures. For example, if the number of consecutive touch failures is greater than or equal to the preset threshold of the number of consecutive touch failures, it is determined that it is not a user's accidental touch, that is, it is determined that the user does have a need to click the function button; if the number of consecutive touch failures is less than the preset threshold of the number of consecutive touch failures, it is determined that it is a user's accidental touch.
[0038] In the case where it is determined that it is not a user's accidental touch, the target function button is determined according to the multiple center positions of the touch points and the center position of the function button obtained within a preset time. For example, when the number of consecutive touch failures within the preset time is 3 times, a total of 3 center positions of the touch points are obtained, and the average value of the 3 center positions of the touch points is used as the target center position of the touch point, and the distances between the target center position of the touch point and the center positions of function button 1 and function button 2 are calculated respectively. If the distance from the target center position of the touch point to the center position of function button 1 is relatively small, it is determined that function button 1 is the target function button; if the distance from the target center position of the touch point to the center position of function button 2 is relatively small, it is determined that function button 2 is the target function button.
[0039] S150, control the touch screen according to the target function button.
[0040] Specifically, after the target function button is determined, the central control system sends a CAN (Controller Area Network) signal to each ECU module, and the ECU module controls the touch screen to display the interface corresponding to the function button.
[0041] The control method of the present application can more accurately identify the user's intention by dynamically analyzing the relationship between the touch point position and the function button position, improving the response accuracy of the touch screen; and still can accurately identify the target function button in the case of inaccurate user operation or interference on the surface of the touch screen, enhancing the robustness of the system.
[0042] In some embodiments, determining the target function button according to the multiple center positions of the touch points and the center position of the function button includes: determining the target center position of the touch point according to the average value of the multiple center positions of the touch points; determining the target function button according to the distance between the target center position of the touch point and the center position of each function button.
[0043] In some embodiments, determining the target function button according to the distance between the target center position of the touch point and the center position of each function button includes: using the function button corresponding to the minimum value of the distance as the target function button.
[0044] Exemplarily, assume that the number of consecutive touch failures within the preset time is 3 times, and a total of 3 contact center positions are obtained. For example, the contact center position 1 is (3, 4), the contact center position 2 is (3, 5), and the contact center position 3 is (2, 3). The average value of the 3 contact center positions is (2.67, 4).
[0045] Assume that the center position of function button 1 is (2, 2), the center position of function button 2 is (3, 3), and the target contact center position is (2.67, 4). The distance between the target contact center position and the center position of function button 1 is 2.1, and the distance between the target contact center position and the center position of function button 2 is 1.1. It can be seen that the distance between the target contact center position and the center position of function button 2 is relatively small, and function button 2 is the target function button.
[0046] In some embodiments, when the number of consecutive touch failures is less than the preset consecutive touch failure number threshold, there is no need to determine the target function button.
[0047] Specifically, when the number of consecutive touch failures is less than the preset consecutive touch failure number threshold, it can be determined that the user has accidentally touched, and there is no need to determine the target function button.
[0048] In some embodiments, determining the number of consecutive touch failures within the preset time based on the distance includes: obtaining the minimum distance among the distances; when the minimum distance is greater than the maximum sensing distance threshold of the preset function button, determining that the touch fails, and recording the number of consecutive touch failures within the preset time. The maximum sensing distance threshold of the preset function button can be determined according to the actual situation and is not specifically limited here.
[0049] Specifically, calculate the distance 1 between the center position of the function button 1 and the center position of the contact point, and calculate the distance 2 between the center position of the function button 2 and the center position of the contact point. When the distance 1 is less than the distance 2, compare the distance 1 with the maximum sensing distance threshold of the preset function button 1 to determine whether the touch fails. For example, if the distance 1 is less than or equal to the maximum sensing distance threshold of the preset function button 1, it is determined that the touch does not fail, and it is determined that the user touches the function button 1. If the distance 1 is greater than the maximum sensing distance threshold of the preset function button 1, it is determined that the touch fails. When the distance 2 is less than the distance 1, compare the distance 2 with the maximum sensing distance threshold of the preset function button 2 to determine whether the touch fails. For example, if the distance 2 is less than or equal to the maximum sensing distance threshold of the preset function button 2, it is determined that the touch does not fail, and it is determined that the user touches the function button 2. If the distance 2 is greater than the maximum sensing distance threshold of the preset function button 2, it is determined that the touch fails. When it is determined that the touch fails, determine the moment of the first touch failure as the moment t, and start recording the touch failure times from the moment t until the moment t + 3, then the continuous touch failure times within the preset time (3 s) can be determined.
[0050] It should be noted that if the touch failure is first determined at the moment t, but the touch is determined to be effective at the moment t + 2, and the recorded continuous touch failure times are less than the preset continuous touch failure times threshold, then the recording of the continuous touch failure times is interrupted, and directly determine that the function button corresponding to the effective touch is the target function button.
[0051] In some embodiments, the center position of the contact point includes the abscissa of the center of the contact point and the ordinate of the center of the contact point, and the center position of the function button includes the abscissa of the center of the function button and the ordinate of the center of the function button. Determining the distance between the center position of the contact point and the center position of each function button includes: determining a first absolute value based on the absolute value of the difference between the abscissa of the center of the contact point and the abscissa of the center of the function button; determining a second absolute value based on the absolute value of the difference between the ordinate of the center of the contact point and the ordinate of the center of the function button; determining the sum of the square of the first absolute value and the square of the second absolute value; performing a square root calculation on the sum value to determine the distance between the center position of the contact point and the center position of the function button.
[0052] Exemplarily, assume that the center position 1 of the contact point is (3, 4) and the center position of the function button is (2, 2), then the first absolute value is 1, the second absolute value is 2, and the distance between the center position of the contact point and the center position of the function button is 1 2 +2 2 = 2.2.
[0053] As a specific example, referring to Figure 2 , the control method of the touch screen according to the embodiment of the present application may further include the following steps:
[0054] S201, Touch sensing module.
[0055] S202, Touch signal.
[0056] S203, The ECU processes the touch signal to obtain the center position of the contact point, and calculates the distance between the center position of the contact point and the center position of each function button.
[0057] S204, Determine the minimum distance among the distances between the center position of the contact point and the center position of each function button.
[0058] S205, Determine whether the minimum distance is greater than or equal to the maximum sensing distance threshold of the preset function button. If so, execute S206; otherwise, execute S201.
[0059] S206, Wait for a preset time, and record the number of consecutive touch failures within the preset time.
[0060] S207, Determine whether the number of consecutive touch failures is greater than or equal to the preset number of consecutive touch failure thresholds. If so, execute S208; otherwise, execute S201.
[0061] S208, Take the average value of the multiple center positions of the contact points as the target center position of the contact point.
[0062] S209, The distance between the target center position of the contact point and the center position of each function button determines the target function button.
[0063] S210, Central control system.
[0064] S211, Send a CAN signal to each ECU module for control.
[0065] In summary, the control method of the present application can effectively identify the accidental touch or sliding operation of the user by calculating the distance between the center position of the contact point and the center position of each function button, and reduce the occurrence of misoperations; when the number of consecutive touch failures exceeds the threshold, the target function button is automatically determined according to the multiple contact positions, avoiding repeated operations by the user and improving the use convenience; by dynamically analyzing the relationship between the contact position and the function button position, the user intention can be more accurately identified, improving the response accuracy of the touch screen; and in the case of inaccurate user operations or interference on the surface of the touch screen (such as stains, water stains), the target function button can still be accurately identified, improving the robustness of the system; it can also reduce the dependence on high-precision hardware sensors and reduce the device cost.
