Automatic switching of the driving mode is achieved.

Preferably, the foregoing user equipment includes, but is not limited to, a smart phone, a tablet computer, and other portable devices with a touch screen can also automatically switch the driving mode by using the above method. In particular, the embodiment of the present invention can be applied to a mobile phone with a touch screen and a touch screen; in the embodiment of the present invention, detecting a message generated by touching the touch screen of the user equipment The function of the number is to determine whether there is a user holding or touching the user equipment. Therefore, in the user equipment having the sensor for detecting the user operation on the frame, the sensors can also be regarded as an extension of the touch screen, and should also be It is within the scope of protection of the embodiments of the present invention. In the embodiment of the present invention, a mobile phone with a touch screen is taken as an example for description and description; for example, the mobile phone detects the state of the user equipment; and when detecting that the state of the user equipment is the first preset state, The operating mode of the user device is switched from the current mode to the driving mode.

In the embodiment of the present invention, the state of the user equipment may be detected by a sensor and a touch screen, wherein the sensors include, but are not limited to, a gyro sensor, a gravity acceleration sensor. The determination of the status and the switching of the operating mode can be handled by the processor in the user equipment.

The preset placement state refers to: a preset placement state of the user equipment. For example, the user may preset the horizontal screen state to a preset placement state, or may set the vertical screen state to a preset placement state in advance.

The first preset threshold refers to a speed threshold that can be used to distinguish the normal walking speed of the user. For example, if the walking speed of the person is generally lower than 10 kilometers per hour, the first preset threshold may be set to 10 kilometers per hour. In addition, it should be noted that, in a modified manner according to the embodiment of the present invention, an upper limit threshold of the moving speed of the user equipment may also be set. For example, if the driving speed of the user is generally lower than 120 km/h, the user equipment may be set. The operating mode of the user equipment is switched from the current mode to the driving mode in a case where the moving speed is between 10 km/h and 120 km/h and the other first preset state is satisfied. It should be noted that the above-mentioned speed threshold is only an exemplary description of the embodiment of the present invention, and is not limited to the setting of the preset threshold in the embodiment of the present invention, that is, the first preset threshold may be as needed. Pre-set or set and changed as needed by the user.

The working mode referred to in the embodiment of the present invention is also referred to as a scene mode. The working modes include: conference mode, sleep mode, driving mode, etc. For example, in the conference mode, the ringtone and the SMS notification are set to be muted; in the sleep mode, the data service can be turned off and the ringtone and the SMS notification are set to be muted. The user equipment can switch between these working modes, and the parameter configuration of these working modes can also be customized by the user. The driving mode referred to in the embodiment of the present invention generally refers to: automatic reading of received short messages, automatic hands-free answering by voice calls, and the like. Of course, different terminal manufacturers or equipment manufacturers may have different parameter settings for the driving mode. However, in the embodiment of the present invention, the specific parameters of the driving mode are not limited, for example, in some manufacturers-defined driving modes. Text messages that may be received are not automatically read. The current mode referred to in the embodiment of the present invention refers to an operation mode in which the user equipment is currently set, including but not limited to a conference mode, a silent mode, a sleep mode, and the like, and may even be a certain mode for driving (for example, : Mode for low speed driving, for high speed driving mode).

For example, in a case where it is detected that the state of the user equipment is the second preset state, the operating mode of the user equipment is switched from the driving mode to the current mode.

The second preset state includes: detecting that the moving speed of the user equipment is lower than a second preset threshold in a plurality of consecutive detection periods. For example, the second preset threshold is 3 km/h; the method of detecting the moving speed in a plurality of consecutive detection periods is to prevent the user from accidentally cutting out the driving mode caused by waiting for a red light or a temporary road congestion. In addition, in some variants of the embodiment of the present invention, after the working mode cuts out the driving mode, the working mode can be automatically switched to other working modes according to the current scene, and is not limited to switching to the current mode before the driving mode.

It is also possible to determine whether the user is operating the user equipment in a plurality of consecutive detection periods by detecting the touch signal on the touch screen. If the user is operating the user equipment during multiple detection cycles, the user may also be considered not currently driving. For example, the second preset state includes detecting a signal generated by touching a touch screen of the user equipment in a plurality of consecutive detection periods. Preferably, the signal generated by the touch screen of the user equipment is: a signal generated by touching an edge position of the touch screen of the user equipment, wherein a width of the edge position can be defined according to requirements, for example, The length (or width) of the user device that is 5% from the border can be defined as the edge position; for the center area of the touch screen of the touch user device (the center area surrounded by the edge position), if the touch touch screen is not detected The touch signal at the edge position can be considered that the user does not hold the user equipment, and the cutting operation of the driving mode may not be performed at this time.

It is possible to determine whether the operating mode of the user equipment is cut out of the driving mode by simultaneously detecting the moving speed of the user equipment and the manner of the touch signal in a plurality of consecutive detection periods.

The automatic switching driving mode can be set with an enabling switch, and the user can select whether to automatically switch the driving mode according to the need, for example, before switching the working mode of the user equipment to the driving mode, determining whether the first enabling switch on the user equipment is Is an open state, wherein the first enable switch is used to indicate whether to enable the function of automatically switching the working mode of the user equipment to the driving mode; when the working mode of the user equipment is switched from the current mode to the driving mode, the When the first enable switch is in an open state and the state of the user equipment is detected as the first preset state, the working mode of the user equipment is switched from the current mode to the driving mode.

In order to make the description of the embodiments of the present invention more clear, the following description and description are given in conjunction with the preferred embodiments.

The existing technical solutions generally describe the functions and features of the driving mode, and are basically manually selected. The preferred embodiment of the present invention can realize automatic switching of the driving mode by continuous multiple condition judgments, and the switching is more accurate and the user experience is better.

At present, the mode of switching to the driving mode is manually set, and if the user is driving, it is dangerous and inconvenient to operate the terminal. However, if the change of the acceleration is obtained only by the gravity sensor to determine whether to automatically switch the driving mode, it is easy to cause an erroneous operation. For example, when the user drives the mobile phone, the mobile phone is placed in a bag or other place, or the terminal user is not a driver but a passenger. The mobile phone is watching the video on the mobile phone, according to the setting of the driving mode, if there is a short message, all the voices are read out. It is not conducive to protecting the user's private information, and the user experience is degraded.

In order to automatically and accurately determine the switching of the driving mode, the driving mode is automatically switched. A preferred embodiment of the present invention provides a system and method for detecting a driving mode and automatic switching of a borderless handset. In the preferred embodiment of the present invention, a borderless mobile phone is taken as an example for description. Among them, the borderless mobile phone refers to a mobile phone whose touch screen is almost the same width as the mobile phone.

In the solution provided by the preferred embodiment of the present invention, the mobile phone includes four modules: the first module is set to obtain whether the screen is in a landscape state (or a portrait state, determined according to a preset state); the second module is It is set to determine whether the touch screen (for example, the capacitive touch screen) has a hand grip point; the third is set to detect whether the horizontal movement speed of the terminal is within the set range value; the fourth module is set to acquire Judging the result and judging whether or not to automatically switch to the driving mode based on the result. For example, if the conditional judgment of the first three modules is established, that is, the current horizontal screen (or vertical screen), and there is no hand holding point, the moving speed is between 20 km/h and 200 km/h, and the fourth time. When the module obtains the judgment result, the system automatically turns on the driving mode of the mobile phone; otherwise, it does not open.

Similarly, after the system turns on the driving mode, if it detects that the following three conditions are met: the speed is 0, and it is in the horizontal screen (or vertical screen), and there is a hand grip point at the border and the hand holding time exceeds the preset time of the user. The value is judged to be in the state of ending the driving, and the driving mode is automatically turned off at this time. Also, the system provides a switch that can turn the automatic switching mode on and off. The default is on.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described and illustrated with reference to the accompanying drawings.

First, the automatic switching driving mode detection and implementation process

The conditions for switching the driving mode provided by the preferred embodiment include: acquiring the current mobile phone as a horizontal screen (or a vertical screen), no hand holding, and moving speed within a set range. The flow chart of the judgment and switching method is shown in FIG.

The following three judgments of the conditions are described and explained separately.

Condition one, get the current mobile phone as a horizontal screen (or vertical screen)

Get the horizontal and vertical screen status of the terminal. Whether the terminal is in the horizontal and vertical screen state can be obtained by the operating system of the terminal, and the system has a function of judging the horizontal and vertical screens, and obtaining the return value can obtain the current horizontal and vertical screen state.

Condition 2, detecting whether the terminal is in the hand state

Whether the terminal has a hand or not can be judged by the touch screen detecting whether there is a hand grip point; due to the characteristics of the borderless mobile phone (or a narrow-framed mobile phone), when the terminal has a hand grip, the edge of the screen border of the touch screen or There will be contacts in the main area of the screen. As long as any part of the contact is detected, the condition is judged not to pass. How to detect if there is a contact and how to obtain the contact position will be explained below.

1) We commonly refer to capacitive screens, including touch screens and integrated circuits (ICs). The touch screen is also the transparent part of our hand touch operation; the touch IC chip is used to calculate the position coordinates of the contact when the capacitive screen is touched, which is calculated and processed by the chip.

2) Nowadays, tablet PCs, mobile phones, and car phones basically use projected capacitors. The capacitive screen is plated with ITO (ie, indium tin oxide) on the surface of the glass to form horizontal (horizontal) and vertical (vertical) electrode arrays. The electrodes respectively form a capacitance with the ground, so that the projected capacitance constitutes an axis coordinate type sensing unit matrix: the vertical rows and columns of the axis coordinate sensing unit, and the X is realized by two intersecting sliders (with sensing function) The shaft slider and the Y-axis slider detect the change in capacitance of each of the sensing units. When the finger touches the capacitive screen, the capacitance of the finger will be superimposed on the screen capacitance, which increases the capacitance of the screen.

3) In the touch detection, the capacitive screen sequentially detects the horizontal and vertical electrode arrays respectively, and determines the lateral coordinates and the longitudinal coordinates according to the change of the capacitance before and after the touch, and then combines them into planar touch coordinates. The scanning method of the capacitor is equivalent to projecting the touch points on the touch screen to the X-axis and Y-axis directions, respectively, and finally combining the coordinates of the touch points. The process of parsing is done by the touch IC chip, and the driver of the operating system of the terminal acquires this coordinate.

4) The system makes the following judgments on the acquired touch coordinates:

a) As shown in Figure 4, the black solid border represents the entire screen area of the phone. If the screen is obtained as a vertical screen state at this time, it is judged that the X-axis distance of the contact coordinates is the distance from the contact to the left edge of the terminal, and greater than zero is less than 5% of the entire touch screen width or greater than 95% of the entire touch screen width. 100%, the contact is obtained at both sides of the position and the border. If the X-axis distance of the contact is between 5% and 95% of the width of the entire touch screen, the contact is acquired and operated in the main area of the screen. . The calculation of the percentage is judged by the pixel point of the contact, for example, the screen resolution of the mobile phone is 1280*720, that is to say, the distance of each length of the screen has 1280 pixels, and each width direction Both are 720 pixels. If the X-axis direction of the pixel of the contact at this time is the width direction is 720*5%=36 or 720*95%=684, then the contact is two in the border. Side, if it is greater than 36 and less than 684, the contact is in the main area of the screen.

b) As shown in Figure 5, the solid black border represents the entire screen area of the phone. If the screen acquired at this time is in the horizontal screen state, the Y-axis distance of the contact coordinates is determined, that is, the distance from the contact coordinates to the lower edge of the end point, as above, if the distance is greater than zero, less than 5% of the entire touch screen width or greater than the entire touch If the screen width is less than 100%, the contact is obtained from the upper and lower sides of the frame. If the Y-axis distance of the contact is between 5% and 95% of the width of the touch screen, the contact is obtained. Operate in the main area of the screen. The calculation of the percentage is judged according to the Y-axis direction of the pixel of the contact. Similarly, the resolution of 1280*720 is taken as an example. In the horizontal screen state, 5% and 95% of the pixel in the Y-axis direction are also 720*. 5% = 36, 720 * 95% = 684.

Condition three, obtain the current moving speed of the terminal, and determine whether it is within the set range value.

The acceleration sensor is a very common configuration of the intelligent terminal, so the moving speed can be obtained by integrating the value of the acceleration sensor once. For example, if the speed value is greater than 20 km/h and less than 200 km/h, if the obtained speed value is greater than 20 km/h and less than 200 km/h, the conditional judgment is established.

Among them, the formula for the acceleration integral to find the speed is as follows:

v=∫a(t)dt, where a represents acceleration and t represents time.

After the above three conditional judgments are made, these judgment values are acquired, and if it is judged that the above three conditions are simultaneously satisfied based on the judgment value, the driving mode is automatically switched. That is, the condition for triggering the automatic switching of the driving mode is that when it is judged to be a horizontal screen (or a vertical screen), and there is no hand holding point at the screen border or in the main area, the speed is between 20 km/h and 200 km/h. In the driving mode of the preferred embodiment of the present invention, incoming calls and short messages are automatically converted into voice playback, and the voice prompts whether navigation is required.

Second, the end of the driving mode detection and implementation process

When automatically switching to driving mode, the system also provides a means to automatically detect and end the driving mode. For example, ending the drive The trigger condition of the driving mode can be:

1) The terminal detects that the horizontal moving speed is zero;

2) There is a grip point at the border, and the timer is activated when the hand contact is detected. For example, if the time exceeds 1 minute, it is judged that the driving end state is at this time. The length of the hand touch time can be set by the user. For example, 20 seconds, 40 seconds, 1 minute or 2 minutes are optional values.

For the method of judging the above two conditions, reference may be made to the foregoing description, and details are not described herein again. If both of the above conditions are satisfied, it is judged that the driving state is ended, and the driving mode can be automatically turned off at this time.

At the same time, the system provides a switch for opening and closing the automatic switching driving mode. The above processing flow is only effective when the switch is turned on. When the user does not need the system to automatically detect the driving mode, the switch can be turned off. As shown in FIG. First, it is judged whether the switch of the automatic switching driving mode of the terminal is ON, and if it is already opened, the above automatic detecting process is performed, and if the switch is off, it ends.

The application scenario of the preferred embodiment of the present invention is described below.

1. Trigger switching driving mode:

The user's terminal is preset to turn on the function of automatically switching the driving mode. When the user is ready to drive the car, the mobile phone horizontal screen is placed on the mobile phone rack or the appropriate position of the car bridge, and the mobile phone obtains the status information of the screen in the horizontal screen (or vertical screen); when the user starts driving the car, The mobile phone continues to obtain the condition that there is no hand holding point at this time. When the car starts, the mobile phone obtains the current moving speed of 20 km/h or more, then all the three conditions are judged to pass, and the mobile phone will automatically switch to the driving mode, the voice Prompt the user whether to open the navigation, the user voice control answer is yes, then directly open the navigation, and convert the SMS and incoming calls into voice mode. The functions in the specific driving mode may vary slightly depending on the terminal.

2. End driving mode

When the user stops driving, at this time, the speed of the system acquiring the mobile terminal becomes 0, and it is judged whether there is a hand grip point at the border of the mobile phone, if the hand grip point is detected on the frame, and the hand touch time is greater than the preset time of the user. For example, for 1 minute, it is known that the driving end state is at this time, and the exit driving mode is automatically turned off.

If the system obtains the speed of the mobile terminal is zero, and there is no hand contact at the border, but the main area of the screen has a hand contact, it is judged that the user may actively operate the screen in a state such as waiting for a traffic light, which does not match When the driving state is finished, the driving mode is not exited.

It should be noted that whether there is a hand grip point in the detection conditions in the above scheme may be replaced by detecting whether there is a hand contact around the borderless frame. Because if the mobile phone is used normally, under normal circumstances, there must be a hand contact at the border, and a borderless mobile phone (or a narrow-sized mobile phone) can just judge this condition. Moreover, in the process of driving mode, a judgment condition may also be added: when automatically switching to the driving mode, if it is detected that there is a hand contact in the main area of the screen, but the mobile phone is still in the horizontal screen state, the system determines At this time, when the user actively operates the mobile phone while driving, the driving mode is not turned off. How to detect that the contact is around the border or in front of the main area of the screen has been explained, no longer here Narration.

As described above, according to the above-described embodiment or the preferred embodiment of the present invention, it is possible to accurately determine whether or not the driving state is automatically determined by the detection and judgment of the continuous condition, thereby automatically switching to the driving mode. In the above embodiment, the terminal acquires the horizontal screen (or vertical screen) and has no hand grip point, and the speed is within the preset range value, indicating that the terminal is already in the driving state, and the terminal automatically switches to the driving mode, the voice. Ask the user if they need to turn on the navigation, and all incoming calls and text messages are converted to voice mode; when the terminal gets the moving speed is zero, and there is a hand grip point at the phone frame and the hand touch time exceeds the time value set by the user, then automatically Turn off the driving mode. The entire process allows users to operate without any manual operation.
