 【detailed description】

The invention will now be described in detail in conjunction with the drawings and embodiments.

Referring to FIG. 1, FIG. 1 is a flowchart of a first embodiment of a method for starting a navigation function in a terminal of the present invention. Including the following steps:

In step S11, the acceleration in the three-axis direction of the terminal is obtained.

In the first unit time, such as 10 seconds, the acceleration of the terminal three-axis direction is obtained, wherein the three axes are the X-axis, the Y-axis, and the Z-axis. The consideration of the length of the first unit time is set according to the period of time when most users pick up the terminal to place the terminal in the fixing bracket of the vehicle, and generally an empirical value can be used.

The acceleration of the X-axis, Y-axis, and Z-axis directions can be obtained by using a gravity acceleration sensor built in the terminal.

In step S12, it is determined whether the absolute values of the acceleration changes in the X-axis and the Y-axis directions respectively reach the first threshold and the second threshold, and it is determined whether the acceleration change value in the Z-axis direction reaches the third threshold.

In the embodiment of the present invention, selecting the judgment of the acceleration changes in the three-axis directions of the X-axis, the Y-axis, and the Z-axis of the terminal as one of the basis for starting the navigation function is obtained by the inventors through extensive research. Because the user needs to open the navigation function of the terminal during the driving process, it is generally necessary to move the terminal from the side to the top of the vehicle center console in the cab "backward" mode. At this time, the terminal will generate correspondingly in the Z direction. The acceleration or acceleration changes; at the same time, when the vehicle moves to the top of the vehicle center console, the terminal is in the upright posture, and the screen of the terminal is also a vertical posture, and the screen needs to be placed horizontally during navigation, so the terminal needs to be horizontally placed. The terminal will simultaneously generate corresponding acceleration or acceleration changes in the X-axis and Y-axis directions.

For example, when the head of the terminal is horizontally placed to the left (ie, the body rotates counterclockwise): the acceleration change process in the X-axis direction is: 0→g (g represents gravitational acceleration), and the acceleration change process in the Y-axis direction is: g→ 0, the acceleration in the Z-axis direction remains basically unchanged.

Or, when the head of the terminal is horizontally placed to the right (ie, the body rotates clockwise): the acceleration change process in the X-axis direction is: 0→-g, and the acceleration change process in the Y-axis direction is: g→0, Z-axis direction The acceleration remains essentially the same.

And, when the terminal is retired, the terminal display screen is fixed to the vehicle navigation bracket for the human body: in actual operation, the process terminal is a process from rest to motion to stationary, and the acceleration in the X and Y directions is basically not maintained. Change, so the acceleration change process in the Z-axis direction is: 0 → N → 0 (N stands for acceleration).

Of course, in the actual data acquisition, taking the data acquisition of the X-axis acceleration as an example, the initial change value of the data of the X-axis direction acceleration may not be 0 or the final change result is difficult to reach g because of the angle or other reasons. In response to this situation, it is necessary to perform a plurality of changes in the data of the acceleration in the X-axis direction to determine a certain threshold range. For the change of 0→g, when the result of the acceleration data in the X-axis direction is finally greater than a certain threshold, it is determined that the acceleration of the terminal in this axial direction has undergone this change. The same 0 → - g, that is, when the final value is less than a certain value.

Similarly, the above-mentioned threshold range and the change of the N value are obtained by multiple simulations, taking the average of the final results of the X-axis, Y-axis and Z-axis three-axis changes.

The first threshold and the second threshold correspond to a rotation operation of the terminal, and the third threshold corresponds to a back-off operation of the terminal. In step S12, if the absolute values of the X-axis and Y-axis acceleration changes respectively reach the first threshold and the second threshold, and the Z-axis acceleration change value reaches the third threshold, step S13 is performed; otherwise, the flow is ended.

In step S13, when the distance between the terminal and the human body reaches the fourth threshold, the navigation function of the terminal is started.

Specifically, when the terminal is determined to be a certain distance from the human body, that is, when the distance between the terminal and the human body reaches the fourth threshold, the navigation function of the terminal is executed. The distance between the terminal and the human body is obtained by using a distance sensor. The principle is that when the infrared data acquired by the distance sensor is weaker than a certain value, the distance between the terminal and the human body reaches a fourth threshold. The fourth threshold is preferably 0.5 meters, and of course, it can be set as the case may be.

In the embodiment of the present invention, by acquiring accelerations in the X-axis, Y-axis, and Z-axis directions per unit time, if the accelerations in the X-axis, Y-axis, and Z-axis directions respectively reach the first, second, and third threshold values, and the distance between the terminal and the human body When the value reaches the fourth threshold, the navigation function of the terminal is automatically started, and the navigation function in the terminal can be intelligently activated, which is convenient for the user, enhances security, and improves the user experience.

In step S203, it is determined whether the acceleration change value in the Z-axis direction reaches a third threshold.

Step S208, starting a navigation function of the terminal.

After the above conditions are met, the event notification mechanism is used to achieve the purpose of automatically starting the navigation function.

In the above steps, the step S202 and the step S203 are sequentially changed, that is, whether the acceleration value in the Z-axis direction reaches the third threshold value, and if the acceleration value in the Z-axis direction reaches the third threshold value, the acceleration change in the X-axis and the Y-axis direction is determined. Whether the absolute value of the absolute value reaches the first threshold and the second threshold, respectively, and if the absolute values of the acceleration changes in the X-axis and the Y-axis direction respectively reach the first threshold and the second threshold, step S204 is performed.

In the embodiment of the present invention, step S206 to step S207 are added, and it is determined whether the acceleration in the Z-axis direction satisfies the fifth threshold value, and whether it meets the driving condition, that is, whether the vehicle is started, thereby reducing the erroneous operation, and being more intelligent and user-friendly. .

In step S302, it is determined whether the absolute values of the acceleration changes in the X-axis and the Y-axis directions respectively reach the first threshold and the second threshold.

If the absolute values of the acceleration changes in the X-axis and Y-axis directions respectively reach the first threshold and the second threshold, step S303 is performed; otherwise, the flow is ended.

In step S303, it is determined whether the acceleration change value in the Z-axis direction reaches a third threshold.

If the acceleration change value in the Z-axis direction reaches the third threshold, step S304 is performed; otherwise, the process ends.

Step S304, obtaining a distance value between the terminal and the human body.

Step S305, determining whether the distance value between the terminal and the human body reaches a fourth threshold.

If the distance between the terminal and the human body reaches the fourth threshold, step S306 is performed; otherwise, the process ends.

Step S306, acquiring the speed of the terminal in the Z-axis direction in the second unit time.

In step S307, it is determined whether the speed in the Z-axis direction reaches the sixth threshold.

The sixth threshold is used to acquire data of the traveling speed of the vehicle through the speed sensor. Specifically, the value is taken multiple times in a certain period of time, and the value with a large normal distribution coefficient is taken. If the value is greater than a certain value, the decision is successful (ie, it indicates that it is different from static or walking). If the speed in the Z-axis direction reaches the sixth threshold, step S308 is performed; otherwise, the flow is ended.

Step S308, starting a navigation function of the terminal.

After the above conditions are met, the event notification mechanism is used to achieve the purpose of automatically starting the navigation function.
