Description

Detection method for included angle of folding screen and electronic equipment

Technical Field

The application relates to the field of terminals, in particular to a detection method for an included angle of a folding screen and electronic equipment.

Background

Currently, electronic devices with folding screens are widely used, and the electronic devices need to control the display state of the folding screen according to the change of the included angle of the folding screen, including controlling to use different display screens, changing display contents, and the like.

How to accurately detect the included angle of the folding screen to accurately manage the display state of the folding screen is a problem to be solved.

Disclosure of Invention

The application provides a detection method for an included angle of a folding screen and electronic equipment. The electronic equipment comprises the folding screen, and the included angle of the folding screen can still be accurately detected when the electronic equipment moves based on the collected acceleration, angular velocity, hall value and the like of the folding screen.

In a first aspect, the present application provides a method for detecting an included angle of a folding screen, where the method is applied to an electronic device having a folding screen, and the method includes: collecting a first acceleration, a first angular velocity and a first Hall value of the folding screen; if the first Hall value is in a first range under the condition that the first acceleration is larger than a first value, determining a folding screen included angle corresponding to the first Hall value in a first corresponding relation between a preset folding screen included angle and the Hall value as the folding screen included angle; and if the first Hall value is out of the first range, determining the included angle of the folding screen according to the first angular speed.

After the method described in the first aspect is implemented, the included angle of the folding screen can still be accurately detected under the movement of the electronic equipment (namely under the condition of unstable acceleration).

The method described in connection with the first aspect, determining the folding screen included angle according to the first angular velocity specifically includes: and integrating the first angular velocity to obtain a change value of the included angle of the folding screen, and superposing the change value on an initial value of the included angle of the folding screen to obtain the included angle of the folding screen.

Therefore, under the condition that the electronic equipment moves (namely, the acceleration is unstable), the change value of the included angle of the folding screen of the electronic equipment is determined through the integration of the angular velocity, and the included angle of the folding screen at a certain moment (for example, the moment t described below) in the moving process is further obtained.

The method described in connection with the first aspect, before the first acceleration of the folding screen is acquired, the method further comprises: collecting a second acceleration of the folding screen; and under the condition that the second acceleration is smaller than or equal to the first value, the initial value of the included angle of the folding screen is obtained through the second acceleration.

The method described in connection with the first aspect, before the first acceleration and the first hall value of the folding screen are acquired, the method further comprises: collecting a second acceleration and a second Hall value of the folding screen; and under the condition that the second acceleration is larger than the first value, if the second Hall value is the boundary Hall value of the first range, the initial value of the folding screen included angle is the folding screen included angle corresponding to the second Hall value in the first corresponding relation.

The method described in connection with the first aspect, before the first acceleration and the first hall value of the folding screen are acquired, the method further comprises: collecting a second acceleration and a second Hall value of the folding screen; and under the condition that the second acceleration is larger than the first value, if the second Hall value is out of the first range, the initial value of the included angle of the folding screen is a preset value.

Therefore, when the electronic equipment is in different motion scenes, the initial value of the included angle of the folding screen in the motion process of the electronic equipment can be accurately and rapidly obtained in different modes. If the electronic equipment is from rest (the acceleration is calculated to be smaller than or equal to a first value at the moment t-1) to movement (the acceleration is calculated to be larger than the first value at the moment t and then the electronic equipment moves), the initial value of the folding screen included angle during movement is the folding screen included angle calculated based on the acceleration at rest; if the electronic equipment moves from the moment when the acceleration is calculated to be greater than a first value (namely movement) to the moment when the acceleration is calculated to be greater than the first value (still movement) when the electronic equipment moves (moment when the acceleration is calculated to be greater than the first value), the initial value of the folding screen included angle during movement is the folding screen included angle queried based on the detected Hall value boundary value during the previous movement; if the Hall value detected when the electronic equipment moves from the moment (t-1) to the moment when the acceleration is greater than the first value, namely the movement is continued (the moment when the acceleration is greater than the first value and still moves), and the Hall value detected when the electronic equipment moves before the moment (t-1), the initial value of the included angle of the folding screen is a preset value, and the preset value is an intermediate angle value which can be unfolded by the folding screen.

The method described in connection with the first aspect, before the first acceleration of the folding screen is acquired, the method further comprises: collecting a second acceleration of the folding screen; and if the second acceleration is smaller than the first value, obtaining the included angle of the folding screen based on the second acceleration.

Therefore, when the acceleration of the electronic equipment is detected to be stable (equivalent to the static state of the electronic equipment), the accurate folding screen included angle can be calculated directly based on the acceleration.

The method described in connection with the first aspect, the first angular velocity comprising a sequence of a plurality of angular velocities.

Therefore, the sequence of the plurality of angular velocities acquired in the period of time can be integrated, and further the change value of the folding screen in the period of time for acquiring the sequence of time can be accurately calculated.

The method described in connection with the first aspect, before the first acceleration, the first angular velocity and the first hall value of the folding screen are acquired, the method further comprises: the folding screen is detected to be bright.

Thus, since the user is less likely to further operate the folding screen in the state where the folding screen is off or off, and is more likely to further perform an operation of unfolding/closing the folding screen in the state where the folding screen is on. Therefore, after the folding screen is lightened, the sensor is controlled to acquire corresponding data, so that the sensor can be prevented from acquiring meaningless data, and the power consumption of the electronic equipment is reduced. The method described in connection with the first aspect, the folding screen comprising at least a first display screen and a second display screen, the method further comprising:

When the included angle of the folding screen is smaller than a first threshold value, displaying information through the first display screen, and displaying information not through the second display screen; and when the included angle of the folding screen is larger than a second threshold value, displaying information through the first display screen and the second display screen.

Therefore, the change condition of the included angle of the folding screen can be combined with the display requirement of a user on the folding screen, and the display state of the folding screen can be controlled.

The method described in connection with the first aspect, the first display screen and the second display screen are both provided with an acceleration sensor and a gyro sensor; the first display screen is also provided with a Hall sensor, and the second display screen is also provided with a magnetic field generating device corresponding to the Hall sensor.

In combination with the method described in the first aspect, in the first corresponding relationship, hall values corresponding to different folding screen included angles are different.

Therefore, when the Hall values corresponding to the included angles of different folding screens are different, if the included angles of the folding screens which are inquired according to the collected Hall values are also different, the unique corresponding included angle of the folding screen can be accurately inquired.

The method described in connection with the first aspect, the electronic device further includes a folding screen angle detection module, the folding screen angle detection module operates in a sensor hub of the electronic device, and the folding screen angle detection module is configured to: under the condition that the first Hall value is in the first range, determining a folding screen included angle corresponding to the first Hall value in the first corresponding relation as the folding screen included angle; and determining the included angle of the folding screen according to the first angular speed when the first Hall value is out of the first range.

Thus, the folding screen included angle can be detected through the sensor hub. The power consumption of the CPU is reduced.

In a second aspect, the present application provides an electronic device comprising a folding screen, one or more memories, one or more processors; the memory is coupled to the one or more processors, the memory for storing computer program code comprising computer instructions that the one or more processors call to cause the electronic device to perform the method as described in any of the first aspects.

In a third aspect, the application provides a computer readable storage medium comprising instructions which, when run on an electronic device, cause the electronic device to perform a method as described in any of the first aspects.

In an application scenario of an electronic device with a folding screen, a user may control a display state of the folding screen according to a change of an included angle of the folding screen during folding/unfolding of the folding screen, including but not limited to controlling to use different display screens, changing display contents, and the like.

Referring to fig. 1A to 1C, fig. 1A to 1C schematically illustrate an application scenario of a set of folding screens provided by an embodiment of the present application.

1A-1C are only shown by way of example as folding screens of an electronic device, including A, B, and C screens, and should not be construed as limiting the application. Wherein, A screen and B screen belong to the internal folding screen, and C screen belongs to the external folding screen, because at folding screen expansion in-process, mainly through A screen display information, consequently A screen can regard as the main screen, and B screen and C screen regard as the auxiliary screen. In addition, because the B screen in the inner folding screen and the C screen of the outer folding screen are parallel to each other, the included angle of the folding screen is as followsThe included angle of the A screen and the B screen can be represented, and the included angle of the A screen and the C screen can also be represented. In the embodiment of the application, the screen A can be also called a first display screen, and the screen B can be also called a second display screen.

Fig. 1A exemplarily shows a display state of a folding screen of an electronic device in a closed state.

As shown in FIG. 1A, when the folding screen is in a closed state, the included angle of the folding screen is 0 DEG, which is recorded as. At this time, the folding screen may be in a screen-off state, or information may be displayed through the C screen (for example, a screen-off interface, an unlock interface, an arbitrary interface after unlocking, etc.) but the a screen and the B screen are always in a screen-off state.

Fig. 1B exemplarily shows a display state of a folding screen of an electronic device during unfolding.

As shown in fig. 1B, in the process of closing the folding screen to unfolding the folding screen, the included angle of the folding screen gradually increases, and with the change of the included angle, the electronic device switches different display screens to display information. For example, when the included angle exceeds the first threshold, the electronic device displays information through the A screen, and the B screen and the C screen are in the off-screen state, which is shown in (a) of FIG. 1BWhen the information is displayed by the screen A; for example, when the angle is further expanded to exceed the second threshold, the electronic device displays information together through the A screen and the B screen, and the C screen is in the off-screen state, see in fig. 1BAnd when the information is displayed by the screen A and the screen B together. Wherein the first threshold value is smaller than the second threshold value, which may be, for example +. >The second threshold value may be, for example +.>The first threshold value and the second threshold value are not particularly limited in the embodiment of the application.

Fig. 1C exemplarily shows a display state of a folding screen of an electronic device in a fully unfolded state.

As shown in FIG. 1C, when the folding screen is completely unfolded, the included angle of the folding screen is 180 degrees, which is recorded asAt this time, the information can be displayed through the screen A and the screen B, and the screen C is in the off-screen state.

Alternatively, the folding screen of the electronic device may include only the inner folding screen and not the outer folding screen, which is not limited by the embodiment of the present application.

Optionally, the electronic device is not limited to changing the display screen used when the included angle of the folding screen changes, and may also change the display content in the display screen, etc. The above-described fig. 1A-1C are only shown by way of example of a display screen used for electronic device modification, and should not be construed as limiting the application.

Alternatively, the above-mentioned folding screen angles and the corresponding display screens are only examples, and should not be construed as limiting the application.

In order to realize the function of controlling the display state of the folding screen based on the change of the folding screen included angle, the folding screen included angle needs to be detected, and particularly, how to accurately detect the folding screen included angle under the condition that the electronic equipment is still in a moving state while a user opens/closes the folding screen is a problem to be solved.

In order to solve the problems, the application provides a detection method of an included angle of a folding screen and electronic equipment. The electronic equipment comprises a folding screen, and under the condition that the electronic equipment is in a motion state based on acceleration acquired at the moment t, if the Hall value acquired at the moment t belongs to a first range, an angle corresponding to the Hall value acquired at the moment t is determined from a preset relation to be used as an included angle of the folding screen; if the Hall value acquired at the moment t does not belong to the first range, calculating the change value of the included angle of the folding screen based on the angular velocity acquired at the moment t, and then combining the initial value and the change value of the included angle of the folding screen to obtain the final value of the included angle of the folding screen.

After the scheme provided by the application is implemented, the collected Hall value angular velocity is less interfered by the movement of the electronic equipment relative to the acceleration, so that the electronic equipment can be ensured to calculate an accurate folding screen included angle through the collected Hall value/angular velocity in the movement state. However, in the state that the electronic device is in motion, the collected acceleration has larger components in the x, y and z axes, the acceleration data is unstable, and the calculated included angle of the folding screen based on the acceleration data has larger difference from the actual one.

In a further implementation, before the sensor is controlled to collect the corresponding data, a corresponding trigger mechanism needs to be detected, for example, after the folding screen (any one or more display screens included in the folding screen) is detected to be on, the sensor is controlled to collect the corresponding data. Since the user is less likely to further operate the folding screen in the state where the folding screen is off or off, and is more likely to further perform an operation of unfolding/closing the folding screen in the state where the folding screen is on. Therefore, after the folding screen is lightened, the sensor is controlled to acquire corresponding data, so that the sensor can be prevented from acquiring meaningless data, and the power consumption of the electronic equipment is reduced.

In a further implementation manner, a corresponding relation (also called a first corresponding relation) between the included angle of the folding screen and the hall value is preset in the electronic device, but only the corresponding relation between the included angle of the folding screen in the second range and the hall value is pre-stored, and the hall value corresponding to the included angle of the folding screen in the corresponding second range is in the first range. The embodiment of the application does not limit specific numerical values of the first range and the second range, and adopts the Hall sensors with different specifications and the Hall sensors arranged at different positions in different electronic equipment sizes, and adopts the magnetic field generating devices with different specifications, so that the corresponding relation between the detected Hall values and the included angles of the folding screens can be different, and therefore, the application only needs to ensure that the included angles of different folding screens folded in the second range can respectively correspond to different Hall values. In a further implementation manner, in the case that the electronic device is in motion at the time t and the hall value acquired at the time t does not belong to the first range. The initial value used for calculating the included angle of the folding screen can be determined by judging the motion state at the time t-1 and then based on the acceleration/Hall value acquired at the time t-1, and the following 3 modes are specifically referred to:

Mode 1: under the condition that the electronic equipment is in a static state based on the acceleration acquired at the time t-1, taking the folding screen included angle calculated based on the acceleration acquired at the time t-1 as an initial value of the folding screen included angle at the time t (namely, the folding screen included angle at the time t-1).

Mode 2: under the condition that the electronic equipment is in a motion state based on the acceleration acquired at the time t-1, and under the condition that the Hall value acquired at the time t-1 is the boundary Hall value of the first range, taking the angle corresponding to the boundary Hall value of the first range acquired at the time t-1 (namely one boundary angle of the second range) as the initial value of the included angle of the folding screen at the time t.

Mode 3: under the condition that the electronic equipment is in a motion state based on the acceleration acquired at the time t-1, and the Hall value acquired at the time t-1 does not belong to the first range, taking a preset fixed value as an initial value of the included angle of the folding screen, wherein the preset fixed value can specifically select an intermediate value, for exampleThe calculation is performed as an initial value.

If the mode 1 is applied, the folding screen included angle is obtained by directly utilizing the boundary Hall value at the time t-1, and the folding screen included angle at the time t can be rapidly and accurately calculated as the initial value of the adopted folding screen included angle at the time t. This is because, in the stationary state of the electronic apparatus, the acquired acceleration is stable (kept at 9.8m/s ² A range of left and right), a trusted folding screen angle that matches the actual result can be calculated based on the accelerometer.

If the mode 2 is applied, the folding screen included angle is obtained by directly utilizing the boundary Hall value at the time t-1, and the folding screen included angle at the time t can be rapidly and accurately calculated as the initial value of the adopted folding screen included angle at the time t. This is because, when the electronic device is in motion, the collected hall value is hardly affected, and a trusted folding screen angle which matches the actual result can be calculated based on the hall value.

If the method 3 is applied, the preset fixed value is directly utilizedAs an initial value of the adopted folding screen included angle at the time t, the folding screen included angle at the time t cannot be accurately calculated. This is because +.>And not necessarily the actual initial value of the folding screen angle. Therefore, the pair based on ++needs to be filtered by Kalman filtering algorithm>And (3) carrying out filtering treatment on the predicted value of the included angle of the folding screen, namely filtering the predicted value of the included angle of the folding screen which does not meet the condition after multiple iterations, and taking the predicted value of the included angle of the folding screen which finally meets the condition as the final included angle of the folding screen.

For a detailed description of the foregoing method, reference may be made to the method flow shown in fig. 5, and the description of the Operating System (OS) interaction flow introduced in fig. 6, which will not be described in detail herein.

In the embodiment of the application, the memory can be used for storing the corresponding relation between the included angle of the folding screen and the Hall value, the corresponding relation can be obtained through pre-testing, and the testing method and the testing result are as follows:

fig. 3 is a schematic diagram schematically illustrating a correspondence relationship between a hall value and an included angle of a folding screen according to an embodiment of the present application.

As shown in fig. 3, the testing method includes: a screen A/B in the folding screen is provided with a Hall sensor, and a magnetic field generating device corresponding to the Hall sensor is correspondingly arranged in the screen B/A in the folding screen. When the hall sensor is close to the magnetic field generating means, the magnetic field strength, i.e. the hall value, can be detected. Thus, the hall value (i.e., the magnetic field strength) acquired by the hall sensor at different folding screen angles can be measured by gradually expanding/closing the folding screen.

As shown in fig. 3, the test results show: in the process of unfolding the folding screen, the included angle of the folding screen gradually becomes larger, which is equivalent to that the screen A and the screen B are gradually far away from each other by lamination, so that the Hall sensor is gradually far away from the magnetic field generating device, and the Hall value acquired by the Hall sensor is gradually reduced. In particular, when the unfolded and folded screen exceeds a certain value (e.g) Then, as the included angle of the folding screen is continuously increased, the corresponding decrease trend of the Hall value is not obvious, namely, different included angles of the folding screen possibly correspond to the same Hall value, so that the test result exceeding a certain range has no meaning on the test result per se, but->To->The corresponding hall values of different folding angles of the range of (a) have larger difference, the unique corresponding folding screen included angle can be accurately inquired according to the collected hall values, the corresponding hall value differences of different folding screen included angles beyond the second range are smaller or even the same, and the unique corresponding folding screen included angle cannot be accurately inquired if a plurality of corresponding different folding screen included angles are possibly inquired according to the collected hall values. Therefore, only the second range, e.g. +.>To->The corresponding relation between the included angle of the folding screen and the Hall value in the range is only needed. The hall value and folding screen angle correspondence shown in fig. 3 is only an example, in the following In another implementation manner, the corresponding relationship between the hall value and the included angle of the folding screen may also be a list, etc., which is not limited in the embodiment of the present application.

The test method and the test result shown in fig. 3 are only examples, and specific numerical values of the first range and the second range are not limited, and in different sizes of electronic devices, the hall sensors with different specifications and the hall sensors installed at different positions are adopted, and the corresponding relation between the detected hall value and the included angle of the folding screen is possibly different due to the adoption of the magnetic field generating devices with different specifications, so that only the different included angles of the folding screen folded in the second range are required to be ensured to be respectively corresponding to different hall values.

The keys 190 include a power-on key, a volume key, etc. The keys 190 may be mechanical keys. Or may be a touch key. The electronic device may receive key inputs, generating key signal inputs related to user settings and function controls of the electronic device.

The software system of the electronic device may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. In the embodiment of the application, an Android system with a layered architecture is taken as an example, and the software structure of the electronic equipment is illustrated by an example.

Fig. 4 is a schematic diagram schematically illustrating a software architecture of an electronic device according to the present application.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. The software architecture includes an application layer, an application framework layer, a hardware abstraction layer (Hardware Abstraction Layer, HAL), and a kernel layer. The Sensor driver (including an acceleration Sensor driver, a gyroscope Sensor driver and a Hall Sensor driver) in the inner core layer, the folding screen included angle detection module in the HAL layer and the like run in a Sensor control center (Sensor hub) in the electronic equipment. The remaining modules are run in the CPU of the electronic device.

Sensor hub is used to realize centralized control of the sensors and reduce the load of the central processing unit (Central Processing Unit, CPU). The Sensor hub corresponds to a micro-program controller (Microprogrammed Control Unit, MCU) on which a program for driving the plurality of sensors to operate can be run, that is, the capability of mounting the plurality of sensors can be supported in the Sensor hub. It can be used as a separate chip, placed between the CPU and various sensors (Sensor), or integrated in an application processor (application processor, AP) in the CPU.

In the embodiment of the application, the Sensor hub mainly provides a folding screen included angle detection function, and particularly provides detection service through a folding screen included angle detection module. The following describes in detail how the folding screen included angle detection function is implemented through Sensor hub.

Sensor hub has two basic functions:

(1) Sensor hub may support on-board Sensor drives (including acceleration Sensor drives, gyroscopic Sensor drives, and hall Sensor drives). Thus, the Sensor hub can control the Sensor to collect data under the condition that the CPU is dormant.

(2) The Sensor hub can receive corresponding data (acceleration, angular velocity and hall value) reported by Sensor drivers (including acceleration Sensor drivers, gyroscope Sensor drivers and hall Sensor drivers), and perform independent/fusion processing on the data, so that an included angle of a folding screen is detected, and an Application Processor (AP) in a CPU does not need to be reported to be judged by the CPU.

Further, when the Sensor hub detects that the included angle of the folding screen can report to the whole machine management service module in the CPU, the whole machine management service module determines the display state of the display screen, or only when detecting that the change/variation value of the included angle of the folding screen meets the condition, the Sensor hub reports to the whole machine management service module in the CPU.

The application layer may include a series of application packages.

As shown in fig. 4, the application package may include applications such as music, video, talk, bluetooth, etc.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions.

As shown in fig. 4, the application framework layer may include a complete state management server, and may also include some window managers, content providers, view systems, phone managers, resource managers, notification managers, etc., not shown in fig. 4.

The whole machine state management server can be used for registering the service for detecting the folding screen included angle to the folding screen included angle detection module through the Sensor hal in the hal layer, so that the folding screen included angle detection module starts to detect the folding screen included angle and reports the detection result to the whole machine state management server through the Sensor hal.

Optionally, the complete machine state management server may be specifically used to register a service for detecting the folding screen included angle with the folding screen included angle detection module through the Sensor hal in the hal layer when the display screen is on, and notify the folding screen included angle detection module to end the service for detecting the folding screen included angle through the Sensor hal in the hal layer when the display screen is off or off, so as to save power consumption of the electronic device.

The complete machine state management server may also manage the display states of the display screens of the electronic device according to the change of the included angles of the folding screens, such as opening/closing one or more display screens in the folding screens, changing the content displayed by the display screens, etc., for example, when the included angle of the folding screen is smaller, only using the a screen to display the content, and when the included angle of the folding screen is larger, simultaneously using the a screen and the B screen to jointly display the content, and may also display more content than the content displayed by using the a screen only.

The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc.

The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture.

The telephony manager is for providing communication functions of the electronic device. Such as the management of call status (including on, hung-up, etc.).

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

The HAL is positioned between the kernel layer and the application framework layer and plays a role in supporting the up and down. Specifically, the HAL defines a set of standard interfaces including, but not limited to, sensor HAL, and Camera HAL, fingerprint HAL, etc., not shown in fig. 4.

The interface is defined by the Sensor HAL and can be used for the call of the whole machine state management service, so that the folding screen included angle detection module is informed to start/stop detection. And the coordination hardware starts working (acceleration sensing drive, gyroscope sensor and Hall sensor collect corresponding data).

The kernel layer is a layer between hardware and software. The core layer contains at least display drivers, sensor drivers (including acceleration sensor drivers, gyro sensor drivers, and hall sensor drivers), and may also include camera drivers, audio drivers, etc., not shown in fig. 4.

The sensor driver can control the corresponding sensor to collect data based on the instruction, and the collected data is returned to the folding screen included angle detection module.

Next, a method for detecting the included angle of the folding screen is specifically described.

Referring to fig. 5, fig. 5 schematically illustrates an OS interaction flow provided by an embodiment of the present application.

As shown in fig. 5, the method is performed by the following modules: the complete machine state management service, the sensor hal, the folding screen included angle detection module, the Hall sensor drive, the acceleration sensor drive and the gyroscope sensor drive, and the specific description of the modules can refer to the description of the software architecture of the electronic equipment, so that the description is omitted herein.

As shown in fig. 5, the method specifically includes the following steps:

s11, the whole state management service of the electronic equipment registers the folding screen included angle detection service to the folding screen included angle detection module through the sensor hal.

Specifically, the overall state management service of the electronic device needs to know the included angle of the folding screen first, and then can control the overall state based on the included angle of the folding screen, including controlling the display state of the electronic device, for example, a display screen used or content displayed in the display screen. Therefore, the complete machine state management service needs to register corresponding detection service with the module providing the folding screen included angle detection function, and therefore, the complete machine state management service needs to register the folding screen included angle detection service with the folding screen included angle detection module through the sensor hal.

Optionally, in one possible implementation manner, after the electronic device is started, the complete machine state management service may be started, and the complete machine state management service may register the folding screen included angle detection service with the folding screen included angle detection module directly through the sensor hal. In another possible implementation manner, after the electronic device is started, the complete machine state management service is started, and the complete machine state management service also needs to register the folding screen included angle detection service to the folding screen included angle detection module directly through the sensor hal only when the condition that the preset condition is met is detected, wherein the preset condition can be that the electronic device is on, and the operation of triggering the electronic device to on the screen can be any one.

S13, the folding screen included angle detection module of the electronic equipment informs the Hall sensor to drive and collect data.

S15, the folding screen included angle detection module of the electronic equipment informs the acceleration sensor to drive and collect data.

S17, the folding screen included angle detection module of the electronic equipment informs the gyroscope sensor to drive and collect data.

Specifically, after the folding screen included angle detection module receives the registration service information sent by the upper-layer complete machine state management service, the folding screen detection module informs the corresponding sensor driver to start working so as to acquire corresponding data. For example, it includes notifying hall sensor drive acquisition data, notifying acceleration sensor drive acquisition data, and notifying gyro sensor drive acquisition data.

The optional S13-S17 may be performed separately, or any two or more may be performed together, for example, when the acceleration sensor driver and the gyro sensor driver are combined into one driver, then S15 and S17 may be combined into one notification to be sent, and the embodiment of the present application is not limited thereto.

In addition, the execution sequence between S13 to S17 is not limited in the embodiment of the present application, that is, S15 or S17 may be executed first, S13 may be executed later, and so on.

And S19, driving the Hall sensor of the electronic equipment to drive the Hall sensor to acquire a Hall value.

S21, driving an acceleration sensor of the electronic equipment to drive the acceleration sensor to collect acceleration.

S23, driving the gyroscope sensor of the electronic equipment to drive the gyroscope sensor to acquire angular velocity.

Specifically, after the corresponding sensor drive of the electronic device receives the notification of the folding screen included angle detection module, the corresponding sensor is started to be driven to acquire data and acquire data which is returned by the corresponding sensor, and the method comprises the steps of driving the Hall sensor to acquire a Hall value, driving the acceleration sensor to acquire acceleration and driving the gyroscope sensor to acquire angular velocity.

In addition, the embodiment of the present application does not limit the execution order between S19 to S23, that is, S23 or S21 may be executed first, S19 may be executed later, and so on.

S25, the Hall sensor of the electronic equipment drives the collected Hall value to return to the folding screen included angle detection module.

And S27, the acceleration sensor of the electronic equipment drives the collected acceleration to return to the folding screen included angle detection module.

S29, the gyroscope sensor of the electronic equipment drives the collected angular velocity to return to the folding screen included angle detection module.

Specifically, the sensor driver may continuously return the collected corresponding data to the folding screen included angle detection module in a data stream form, for example, including a hall value data stream, an acceleration data stream, an angular velocity data stream, and the like.

In addition, the embodiment of the present application does not limit the execution order between S25 to S29, that is, S27 or S29 may be executed first, S25 may be executed later, and so on.

S31, a folding screen included angle detection module of the electronic equipment detects a folding screen included angle.

And then the folding screen included angle detection module can detect the folding screen included angle based on the acquired Hall value, acceleration and angular velocity. Specifically, for the specific implementation of the folding screen angle detection module to detect the folding screen angle, reference may be made to the description of the method flows shown in fig. 6 to fig. 7, which is omitted herein for brevity.

S33, the folding screen included angle detection module of the electronic equipment reports the folding screen included angle to the whole machine state management service through the sensor hal.

S35, the whole machine state management service of the electronic equipment manages the whole machine state based on the folding screen included angle.

Specifically, after receiving the detection result of the folding screen included angle reported by the folding screen detection module, the overall state management service of the electronic device can manage states of the electronic device including display states, such as states of a display screen used for management, content displayed in the display screen, and the like, according to the folding screen included angle.

One way to manage this is, for example, to display information through the a screen instead of the B screen when the angle of the folding screen is greater than the first threshold and less than the second threshold, and to display information together through the a screen and the B screen when the angle of the folding screen is greater than the second threshold, which is described above with reference to fig. 1A-1C. Wherein the first threshold value may be, for exampleThe second threshold value may be, for example +.>The first threshold value and the second threshold value are not particularly limited in the embodiment of the application.

In addition, the overall state management service may also have other management policies, which are not limited by the embodiment of the present application.

Fig. 6 is a schematic diagram schematically illustrating a specific implementation method for detecting an included angle of a folding screen according to an embodiment of the present application.

As shown in fig. 6, fig. 6 shows a schematic diagram of a specific implementation method for detecting an included angle of a folding screen in the foregoing step S31, where the method specifically includes the following steps:

and S311, continuously receiving the acquired acceleration, angular velocity and Hall value.

Specifically, the folding screen detection module of the electronic device may continuously receive acceleration, angular velocity and hall value.

The acceleration, angular velocity, and hall value may be received in different data streams, or in one data stream after fusion, respectively, which is not limited in this embodiment of the present application.

And S312, detecting whether the electronic equipment is in a motion state or not based on the acceleration acquired at the moment t.

Specifically, the electronic device determines whether the electronic device is in a motion state based on the acceleration acquired at the time t, for example, when the acceleration is greater than a first value, the electronic device is considered to be in a motion state, and when the acceleration is less than or equal to the first value, the electronic device is considered to be in a stationary state. Wherein the first value is greater than or equal to the gravitational acceleration, i.e. 9.8m/s ² 。

In the embodiment of the application, the motion state and the static state are two opposite concepts, and the static state does not only comprise absolute static, but also can comprise some slight motion states, for example, when a user holds a mobile phone and touches a display screen, the slight motion of the electronic device can be caused.

S313, calculating the included angle of the folding screen based on the acceleration acquired at the moment t.

If it is detected in S312 that the electronic device is not in a motion state, a folding screen angle is calculated based on the acceleration acquired at the time t, where the acceleration acquired at the time t includes the folding screen angle of the a screen and further includes the folding screen angle of the B screen. The angle of the screen A relative to the screen B can be obtained by calculating the acceleration of the two screens.

S314, judging whether the Hall value acquired at the moment t belongs to a first range.

If it is detected in S312 that the electronic device is in a motion state, it is further determined whether the hall value acquired at the time t belongs to the first range. For the definition of the first range, reference may be made to the description of fig. 3 above, and will not be repeated here.

S315, inquiring the included angle of the corresponding folding screen based on the Hall value acquired at the moment t.

If it is detected in S313 that the hall value acquired at the time t belongs to the first range, the hall value acquired at the time t is queried for the corresponding folding screen included angle directly from the corresponding relation between the prestored folding screen included angle and the hall value.

S316, calculating the included angle of the folding screen based on the angular velocity acquired at the moment t.

If it is detected in S313 that the hall value acquired at the time t does not belong to the first range, the folding screen angle needs to be further obtained based on the angular velocity acquired at the time t.

Since it is determined in S312 that the electronic device is in a motion state, when calculating the folding screen angle according to the angular velocity, the folding screen angle change value in the motion process needs to be obtained by integrating the angular velocity, that is, the angular velocity acquired at the time t includes a sequence of a plurality of angular velocities, and the folding screen angle change value in the motion process needs to be obtained by integrating the plurality of sequences. And then, superposing the variation value and the initial value to obtain the initial value of the included angle of the combined folding screen.

The method for determining the initial value of the folding screen angle may refer to the description of the method shown in fig. 7, which is not repeated herein.

Alternatively, the acceleration, hall value, angular velocity, etc. acquired at time t according to the present application may include a plurality of sequence values, not just one value.

In the embodiment of the present application, the acceleration acquired by the electronic device at the time t may be referred to as a first acceleration, the angular velocity acquired by the electronic device at the time t may be referred to as a first angular velocity, and the hall value acquired by the electronic device at the time t may also be referred to as a first hall value.

As shown in fig. 7, the step S316 specifically includes the following steps:

s3161, judging whether the electronic equipment is in a motion state or not based on acceleration acquired at the time t-1.

Specifically, in order to determine the initial value of the included angle of the folding screen of the electronic device in the motion state, the included angle of the folding screen obtained by previous calculation can be used as the initial value of the included angle of the folding screen. Equivalently, the included angle of the folding screen calculated at the time t-1 needs to be used as an initial value of the included angle of the folding screen at the time t. Therefore, whether the electronic equipment is in a motion state or not needs to be detected based on the acceleration acquired at the time t-1, and whether the included angle of the folding screen at the time t-1 can be used as an initial value of the included angle of the folding screen at the time t is further determined.

S3162, taking the included angle of the folding screen at the time t-1 as an initial value of the included angle of the folding screen at the time t, integrating the angular velocity acquired at the time t to obtain a change value of the folding angle, and calculating the included angle of the folding screen at the time t by combining the initial value and the change value.

Under the condition that the electronic equipment is in a static state is determined in S3161, the folding screen included angle calculated based on the acceleration at the time t-1 is directly used as an initial value of the folding screen included angle at the time t, the angular velocity acquired at the time t is integrated to obtain a folding angle change value, and the folding screen included angle at the time t is calculated by combining the initial value and the change value.

This is because, when t-1 determines that the electronic device is in a stationary state, the electronic device calculates the angle of the folding screen accurately, and can be used as an initial value in a moving state at the subsequent time t.

S3163, judging whether the Hall value acquired at the time t-1 belongs to the boundary value of the first range.

In the case that the electronic device is in a motion state in S3161, it is further determined whether the hall value at the time t-1 belongs to a boundary value of the first range, and further it is further determined whether the folding screen included angle at the time t-1 can be used as an initial value of the folding screen included angle at the time t.

S3164, taking the included angle of the folding screen at the time t-1 as an initial value of the included angle of the folding screen at the time t, integrating the angular velocity acquired at the time t to obtain a change value of the folding angle, and calculating the included angle of the folding screen at the time t by combining the initial value and the change value.

Under the condition that the Hall value at the time t-1 determined in S3163 belongs to the boundary value of the first range, directly inquiring the Hall value at the time t-1 to obtain a corresponding folding screen included angle as an initial value of the folding screen included angle at the time t, integrating the angular velocity acquired at the time t to obtain a folding angle change value, and calculating the folding screen included angle at the time t by combining the initial value and the change value.

S3165, taking a preset fixed value (90 degrees) as an initial value of the included angle of the folding screen at the moment t, integrating the angular velocity acquired at the moment t to obtain a change value of the folding angle, and combining the initial value and the change value to obtain the included angle of the folding screen at the moment t by using a Kalman filtering algorithm.

Under the condition that the Hall value at the t-1 moment determined in S3163 does not belong to the boundary value of the first range, taking the preset value as an initial value of the folding screen included angle at the t moment, integrating the angular velocity acquired at the t moment to obtain a folding angle change value, and calculating the folding screen included angle at the t moment by combining the initial value and the change value.

The preset value may be an intermediate value of the included angle of the folding screen, for example, for some folding screens that can be unfolded to 180 °, the preset fixed value may be set to 90 °, and for some folding screens that can be unfolded to 360 °, the preset fixed value may be set to 180 °, which embodiments of the present application are not limited in this respect.

In S3165, the preset fixed value is used as the initial value of the folding screen included angle at the time t-1 instead of the folding screen included angle at the time t-1, because a certain error may occur in the folding screen included angle obtained when the electronic device moves at the time t-1 and the Hall value is not in the first range, and therefore, the intermediate value of the folding screen is selected as the initial value of the folding screen included angle at the time t.

Alternatively, in other embodiments, the preset fixed value may be selected as a common folding screen angle instead of an intermediate value, which is not limited in this embodiment of the present application.

Optionally, the preset fixed value is directly used as the initial value of the adopted folding screen included angle at the time t, so that the folding screen included angle at the time t cannot be accurately calculated. This is because the preset fixed value is not necessarily the actual initial value of the folding screen angle. Therefore, the predicted value of the included angle of the folding screen, which is calculated based on the initial value under the preset fixed value, needs to be filtered through a Kalman filtering algorithm, namely, the predicted value of the included angle of the folding screen which does not meet the condition is filtered through multiple iterations, and the predicted value of the included angle of the folding screen which finally meets the condition is used as the final included angle of the folding screen.

In the embodiment of the application, the acceleration acquired by the electronic equipment at the time t-1 can be called second acceleration, the angular velocity acquired by the electronic equipment at the time t-1 can be called second angular velocity, and the Hall value acquired by the electronic equipment at the time t-1 can be called second Hall value. In the embodiment of the application, the time t-1 is the time before the time t, and the embodiment of the application does not limit the direct difference between the time t and the time t-1, for example, the difference can be determined according to the detection period of the folding screen included angle detection module.

In summary, after the scheme provided by the application is implemented, because the collected Hall value and angular velocity are less interfered by the movement of the electronic equipment relative to the acceleration, the electronic equipment can be ensured to calculate an accurate folding screen included angle through the collected Hall value/angular velocity in the movement state. Furthermore, when the included angle of the folding screen is calculated by integrating the angular speed, the convergence speed of the algorithm can be increased when the adopted included angle of the folding screen is calculated based on the acceleration or Hall value at the time t-1, and the user experience is further improved.
