[0060] The example embodiments will be described in detail herein with reference to the attached drawings. In the following description, same numbers refer to same elements in all figures. The following detailed description does not represent all embodiments consistent with the present disclosure. Instead, they only describe example embodiments consistent with some aspects of the present disclosure, as detailed in the appended claims.

[0061] The present disclosure provides a calibration method applied to a terminal. In the method, a set relationship is calibrated based on magnetic information, thereby avoiding interference caused by external magnetic field and internal structure change of the terminal, better ensuring reliability of the set relationship, and more accurately determining an included angle between a first component and a second component, improving user experience.

[0062] In one example embodiment, a control method is provided, applied to a terminal. Referring to Figure 6 As shown in the figure, the terminal includes a first component 10 and a second component 20, and an included angle a between the first component 10 and the second component 20 is adjustable. The terminal can include a foldable screen, the first component 10 can be a first screen of the foldable screen, and the second component 20 can be a second screen of the foldable screen. Of course, the first component and the second component can also be other structures, which are not limited. For example, the terminal includes a main body and a camera component that can be popped out, the first component can be the main body, and the second component can be the camera component.

[0063] Referring to Figure 1 The method can include:

[0064] S110, determining that the first component and the second component are in a first set state;

[0065] S120, determining difference information according to the second magnetic information and the first magnetic information detected in the first set state;

[0066] S130, judging whether the difference information meets set threshold information; if the result of the judgment is yes, executing step S140; otherwise, executing step S150;

[0067] S140, calibrating the set relationship;

[0068] S150, keep the set relationship unchanged.

[0069] In step S110, the first set state can be a state in which the included angle a between the first component 10 and the second component 20 is 0°, that is, the first component 10 and the second component 20 are in a completely closed state. The first set state can also be a state in which the included angle a between the first component 10 and the second component 20 is 180°, that is, the first component 10 and the second component 20 are in a completely unfolded state. Of course, the first set state can also be other states, which is set according to actual needs, and is not limited.

[0070] Example 1,

[0071] The terminal includes a folding screen, the first component 10 is a first screen of the folding screen, the second component 20 is a second screen of the folding screen, and the first set state can refer to a state in which the included angle a of the first screen and the second screen is 0°. That is, the first set state can refer to a state in which the folding screen is closed. Wherein, whether the folding screen is in a closed state can be detected by cooperation of the magnetic sensor and the magnetic piece.

[0072] It should be noted that the terminal can start the calibration process of the set relationship based on the received control information, and then determine whether the first component 10 and the second component 20 are in the first set state.

[0073] In step S120, the first magnetic information is the magnetic information detected in the first set state. The second magnetic information corresponds to the set relationship before calibration, that is, the second magnetic information is the magnetic information corresponding to the first set state in the set relationship before the current calibration process of the first set state is started. Wherein, the second magnetic information can be directly preset in the terminal, or can be determined according to the first set state and the set relationship before calibration.

[0074] When the second magnetic information is directly preset in the terminal, the second magnetic information can be set before the terminal is shipped, or can be set after the terminal is shipped, and after the second magnetic information is set, the second magnetic information can be modified to better meet the different needs of users.

[0075] In this step, the first magnetic information can be detected by the magnetic field measurement unit. For example, after it is determined that the first component 10 and the second component 20 are in the first set state, the magnetic field measurement unit can detect the magnetic information in the first set state, and then transmit it to the processor (CPU). The processor of the terminal can obtain the above magnetic information, and determine the above magnetic information as the first magnetic information. Wherein, the magnetic field measurement unit can include at least one magnetic sensor, and the magnetic sensor can include a Hall sensor.

[0076] In this step, the processor can determine the difference information based on the first magnetic information and the second magnetic information after obtaining the first magnetic information and the second magnetic information. The magnetic information can include at least one of the magnetic field strength value in the first direction, the magnetic field strength value in the second direction, and the magnetic field strength value in the third direction. The difference information can also include at least one of the magnetic field strength difference value in the first direction, the magnetic field strength difference value in the second direction, and the magnetic field strength difference value in the third direction.

[0077] For example, the first magnetic information can include the first magnetic field strength values in the above three directions, and the second magnetic information can include the second magnetic field strength values in the above three directions. Then, the magnetic field strength difference value in the first direction can be determined based on the first magnetic field strength value and the second magnetic field strength value in the first direction. Similarly, the magnetic field strength difference value in the second direction and the magnetic field strength difference value in the third direction can also be determined. The magnetic field strength difference values in the above three directions constitute the difference information.

[0078] The magnetic field strength difference value can be obtained by subtracting the second magnetic field strength value in the corresponding direction from the first magnetic field strength value in the corresponding direction. For example, the magnetic field strength difference value in the first direction can be obtained by subtracting the second magnetic field strength value in the first direction from the first magnetic field strength value in the first direction.

[0079] It should be noted that the specific directions of the above three directions can be determined according to actual conditions, and are not limited. For example, the above three directions can be perpendicular to each other, such as the X direction, the Y direction, and the Z direction shown in FIG. 1. Figure 6

[0080] In step S130, the threshold information can include at least one of the set threshold value in the first direction, the set threshold value in the second direction, and the set threshold value in the third direction. The set threshold information can be set before the terminal is manufactured, or can be set after the terminal is manufactured. After the set threshold information is set, the set threshold information can also be modified to better meet the different needs of users.

[0081] In this step, the magnetic field strength difference value in each direction can be compared with the set threshold value respectively. If it is determined that at least one of the following three conditions is met, it can be determined that the difference information meets the set threshold information, and step S140 can be performed.

[0082] Condition 1: the absolute value of the magnetic field strength difference value in the first direction is greater than or equal to the set threshold value in the first direction;

[0083] Condition 2: the absolute value of the magnetic field strength difference value in the second direction is greater than or equal to the set threshold value in the second direction;

[0084] Condition 3: the absolute value of the magnetic field strength difference value in the third direction is greater than or equal to the set threshold value in the third direction.

[0085] ​If it is determined that any of the three conditions is not met, it is determined that the difference information does not meet the set threshold information, and step S150 is executed.

[0086] It should be noted that the set threshold of each direction can be set according to actual needs, and the specific value is not limited.

[0087] For example, the set threshold of the first direction can be 6551 microtesla (i.e., uT). The set threshold of the second direction can be 445 uT. The set threshold of the third direction can be 1699 uT.

[0088] In this step, the set relationship represents the mapping relationship between the magnetic information and the included angle a. The set relationship can be set before the terminal is shipped, or can be set after the terminal is shipped, and after the set relationship is set, the set relationship can also be modified to better meet the different needs of users.

[0089] It should be noted that the set relationship can exist in the form of a table, or in the form of a curve, or in the form of a relationship, and no limitation is made. In step S140, the included angle a can be determined based on the detected magnetic information and the set relationship when the magnetic field measurement unit detects the magnetic information.

[0090] Since it has been determined that the difference information meets the set threshold information, it means that the current set relationship cannot accurately determine the included angle a between the first component 10 and the second component 20, so the set relationship can be calibrated, that is, the set relationship is adjusted, and subsequently the included angle a can be determined according to the calibrated set relationship combined with the detected magnetic information to better ensure the accuracy of the included angle a.

[0091] In addition, if the difference information meets one of the three conditions, only the set relationship of the corresponding direction can be calibrated. For example, if only the absolute value of the magnetic field intensity difference of the first direction is greater than or equal to the set threshold of the first direction, only the set relationship of the first direction can be calibrated.

[0092] In step S150, since it has been determined that the difference information does not meet the set threshold information, it means that the current set relationship can still accurately determine the included angle a between the first component 10 and the second component 20, so the set relationship does not need to be adjusted, that is, the set relationship can be directly maintained unchanged, and subsequently the included angle a is still determined by the set relationship.

[0093] In the method, the setting relationship is calibrated based on the magnetic information, so as to avoid the interference caused by the external magnetic field and the change of the internal structure of the terminal, better ensure the reliability of the setting relationship, and more accurately determine the included angle a between the first component 10 and the second component 20 when the angle is detected based on the magnetic element, and improve the user experience.

[0094] It should be noted that in the method, when the setting relationship calibration is completed or it is determined that the setting relationship remains unchanged, the calibration process of this time can be ended.

[0095] In one example embodiment, a calibration method is provided, which is applied to a terminal. As shown in Figure 6 The terminal includes a first component 10 and a second component 20, and the included angle a between the first component 10 and the second component 20 is adjustable. As shown in Figure 2 In the method, the setting relationship is calibrated, which can include:

[0096] S210, determining whether a setting event occurs in the terminal within a setting period; if it is determined that the setting event occurs in the terminal within the setting period, performing step S220; if it is determined that the setting event does not occur in the terminal within the setting period, performing step S230;

[0097] S220, calibrating the setting relationship according to the setting rule;

[0098] S230, calibrating the setting relationship according to the difference value information.

[0099] The setting period can be set before the terminal is shipped, or can be set after the terminal is shipped, and the setting period can also be modified after the setting period is set to better meet the different needs of users.

[0100] The setting period can be set according to actual needs, which can be an interval period for determining the execution of the method. In this case, the method can be executed once every interval period. In addition, the setting period can also be the time when the last execution of the method ends to the time when the execution of the method starts.

[0101] The setting event refers to an event that can affect the internal structure of the terminal. The setting event can include a drop event, and can also include other events that can affect the internal structure of the terminal, which are not limited. The drop event is determined by the acceleration sensor of the terminal, or can be determined by other means, which are not limited.

[0102] In the method, if it is determined that the setting event does not occur within the setting period, it indicates that the internal structure of the terminal has not changed, and it indicates that the interference is affected by the external magnetic field, so the setting relationship can be calibrated directly through the difference value information.

[0103] Example 1,

[0104] The difference information includes a magnetic field strength difference value ΔH1 in the first direction, which is obtained by subtracting the second magnetic field strength value from the first magnetic field strength value in the first direction. ΔH1 can be positive, zero, or negative.

[0105] The setting relationship exists in the form of a curve, that is, the setting relationship includes a setting curve S in the first direction. The abscissa of the setting curve S is the included angle α, and the ordinate is the magnetic field strength value.

[0106] In this example 1, when the difference information meets the setting threshold information, and the terminal does not appear the setting event within the setting period, all the ordinates of the setting curve S in the first direction can be directly added by ΔH1 to form the calibrated setting curve S' in the first direction, that is, if the magnetic field strength value corresponding to one included angle α in the setting curve S is H, then the magnetic field strength value corresponding to this included angle α in the setting curve S' is H+ΔH1. Wherein, if ΔH1 is positive, the setting curve S is translated upwards along the ordinate by |ΔH1| to obtain the setting region S'; if ΔH1 is negative, the setting curve is translated downwards along the ordinate by |ΔH1| to obtain the setting region S'.

[0107] Then the new setting curve S' is used to replace the old setting curve S. In this way, the calibration of the setting curve in the first direction can be completed.

[0108] In addition, in the method, if it is determined that the setting event occurs within the setting period, it indicates that the internal structure of the terminal has changed, and it indicates that the interference is affected by the internal structure change. The setting relationship can be calibrated according to the setting rule.

[0109] As shown in the reference Figure 3 Calibrating the setting relationship according to the setting rule in step S220 can include:

[0110] S231, determining a plurality of included angles of the first component and the second component in the second setting state, and a plurality of third magnetic information corresponding to the plurality of included angles, wherein the plurality of included angles and the plurality of third magnetic information are one-to-one corresponding;

[0111] S232, calibrating the setting relationship according to the plurality of included angles and the plurality of third magnetic information.

[0112] In step S231, the second setting state can be different from the first setting state. For example, the first setting state can be a closed state, that is, the first state can be a state in which the included angle a between the first component 10 and the second component 20 is 0°. The second setting state can be an unfolded state, that is, the second state can be a state in which the included angle a between the first component 10 and the second component 20 is greater than 0°. Wherein, the first component 10 and the second component 20 are in the unfolded state in the second setting state. In this step, a plurality of included angles and third magnetic information corresponding to each included angle need to be determined. Wherein, the plurality of included angles can be determined by other components that can determine the angle. For example, the plurality of included angles can be detected by an inertial measurement unit (IMU).

[0113] Wherein, the plurality of included angles can respectively belong to a plurality of setting angle ranges. The setting angle range can be set before the terminal is shipped, or can be set after the terminal is shipped. In addition, after the setting angle range is set, it can be modified later to better meet the different needs of users.

[0114] Example 2,

[0115] The terminal can set four setting angle ranges, which are 15° to 45°, 45° to 90°, 90° to 135°, and 135° to 180°. Wherein, each of the above angle ranges includes a minimum angle value and does not include a maximum angle value. For example, in the angle range of 15° to 45°, 15° is included, but 45° is not included.

[0116] After determining that the difference value information meets the setting threshold information, and determining that the terminal is in the second setting state of the first component 10 and the second component 20 after the setting event occurs in the setting period, the processor of the terminal can control the setting algorithm to change from the standby state to the running state, so that the terminal can output the indication information to indicate that the included angle between the first component 10 and the second component 20 is driven to the setting angle range. For example, the indication information can be information indicating the corresponding operation, that is, the indication information is used to indicate that the included angle between the first component 10 and the second component 20 is rotated to the above four different setting angle ranges. And record at least one included angle in each setting angle range and the corresponding third magnetic information.

[0117] Wherein, the indication information can be displayed on the display screen of the terminal to guide the user to rotate the first component 10 and / or the second component 20. The indication information can also be broadcast through the microphone of the terminal to guide the user to rotate the first component 10 and / or the second component 20. The specific reminding mode of the indication information can also be other modes, which are not limited.

[0118] Example 3,

[0119] The terminal is a mobile phone including a folding screen. The terminal can set four angle ranges as same as example 2. Wherein, 15° to 45° is recorded as the first angle range, 45° to 90° is recorded as the second angle range, 90° to 135° is recorded as the third angle range, and 135° to 180° is recorded as the fourth angle range.

[0120] In this example, after the processor of the mobile phone controls the setting algorithm to change from the standby state to the running state, one screen in the folding screen can display the first indication information, which is used to instruct the user to fold the folding screen to the first angle range. After the folding angle of the folding screen is fixed, the folding angle and the third magnetic information at this time are collected. So that the processor of the mobile phone obtains one folding angle in the first angle range and the corresponding third magnetic information.

[0121] In addition, after the folding angle of the folding screen is fixed, the folding screen can output the second indication information, which is used to instruct the user to fold the folding screen to the second angle range. After the folding angle of the folding screen is fixed, the folding angle and the third magnetic information at this time are collected. So that the processor of the mobile phone obtains one folding angle in the second angle range and the corresponding third magnetic information.

[0122] Similarly, the processor can obtain one folding angle in each set angle range and the corresponding third magnetic information.

[0123] In step S232, the third magnetic information can include at least one of the third magnetic field strength value of the first direction, the third magnetic field strength value of the second direction and the third magnetic field strength value of the third direction. The setting relationship can include at least one of the setting curve of the first direction, the setting curve of the second direction and the setting curve of the third direction.

[0124] When the third magnetic information includes the third magnetic field strength value of the first direction, the third magnetic field strength value of the second direction and the third magnetic field strength value of the third direction, and the setting relationship includes the setting curve of the first direction, the setting curve of the second direction and the setting curve of the third direction, after the processor of the terminal obtains multiple folding angles and corresponding multiple third magnetic information, the processor can determine the new setting curve of the first direction based on the above multiple folding angles and the corresponding multiple third magnetic field strength values of the first direction. Similarly, the new setting curve of the second direction and the new setting curve of the third direction can be determined. Then, the new setting curve of each direction is used to replace the original old setting curve, so as to complete the calibration of the setting relationship.

[0125] It should be noted that in the method, the new setting curve of the corresponding direction can be directly fitted according to all the included angle angles and all the third magnetic field strength values of each direction. In the method, a first curve of the corresponding direction can be fitted according to a part of the included angle angles and the corresponding part of the third magnetic field strength values of each direction, and a second curve of the corresponding direction can be fitted according to another part of the included angle angles and the corresponding part of the third magnetic field strength values of each direction, and then the new setting curve of the corresponding direction can be fitted according to the first curve and the second curve.

[0126] The calibration of the setting curve of the first direction is taken as an example for introduction below.

[0127] Example 3,

[0128] The plurality of included angle angles can include a first angle A, a second angle B, a third angle C and a fourth angle D, wherein the first angle A is in a range of 15°≤A<45°, that is, the first angle A is greater than or equal to 15° and less than 45°; the second angle B is in a range of 45°≤A<90°, the third angle C is in a range of 90°≤A<135°, and the fourth angle D is in a range of 135°≤A<180°.

[0129] The third magnetic field strength value of the first direction corresponding to the first angle A is H A1 . The third magnetic field strength value of the first direction corresponding to the second angle B is H B1 . The third magnetic field strength value of the first direction corresponding to the third angle C is H C1 . The third magnetic field strength value of the first direction corresponding to the fourth angle D is H D1 .

[0130] In this example, the new setting curve of the first direction is fitted according to the first angle A, the third magnetic field strength value H A1 , the second angle B, the third magnetic field strength value H B1 , the third angle C, the third magnetic field strength value H C1 , the fourth angle D and the third magnetic field strength value H D1 , and then the new setting curve is used to replace the original setting curve. In this way, the calibration of the setting curve of the first direction can be completed.
