Referring to fig. 1, a schematic flowchart of a method for monitoring a vehicle navigation state according to an embodiment of the present invention is provided. As shown in fig. 1, the method may include the steps of:
step S101, judging whether the terminal is in a non-sleep state, and if the terminal is in the non-sleep state, entering step S102; otherwise, the process proceeds to step S106.
In this embodiment, whether the terminal is in the non-sleep state may be determined by detecting whether the CPU of the terminal is running, and if it is detected that the CPU of the terminal is running, it indicates that the terminal is in the non-sleep state; and if the CPU of the terminal is detected not to be operated, the terminal is in a sleep state.
In this embodiment, it may also be determined whether the terminal is in a dormant state by detecting whether a program in the terminal is transmitting and receiving network data, and if it is detected that the program is transmitting and receiving network data, it indicates that the terminal is in a non-dormant state; otherwise, the device is in a dormant state.
In this embodiment, it may also be determined whether the terminal is in a non-sleep state by reading the attribute of the system, and when the terminal is in the sleep or non-sleep state, corresponding content is recorded on the attribute of the system.
Step S102, monitoring whether a change value of an included angle between a terminal plane and a horizontal plane within a first preset time is smaller than a first preset threshold, and if the change value is smaller than the first preset threshold, entering step S103; otherwise, the process proceeds to step S106.
When the terminal is used for vehicle-mounted navigation, the terminal is generally fixed on a mobile phone support installed in a vehicle, so that when the terminal is in a vehicle-mounted navigation state, an included angle of a terminal plane relative to a horizontal plane is always relatively fixed, and the change is small. Therefore, in this embodiment, if it is monitored that the change value of the included angle between the terminal plane and the horizontal plane within the first preset time is smaller than the first preset threshold, the step S103 is performed; otherwise, it indicates that the terminal is in the non-sleep state, and directly jumps to step S106.
Further, in this embodiment, the monitoring a change value of an included angle between the terminal plane and the horizontal plane within a first preset time includes:
the terminal acquires three-axis data of the gravity sensor at intervals, calculates an included angle between a terminal plane and a horizontal plane according to the acquired three-axis data of the gravity sensor, compares the included angle obtained by the calculation with the included angle obtained by the previous calculation to obtain a change value of an included angle in two time points, and analogizes in turn to obtain a change value of the included angle between the terminal plane and the horizontal plane in the first preset time.
The three-axis data of the gravity sensor are vector force data of X, Y, Z three-axis gravity acceleration of a default coordinate system in the terminal, wherein X, Y axes are two sides of a terminal plane, a Z axis is perpendicular to the terminal plane, and a schematic diagram of the coordinate system is shown in fig. 2. Wherein, calculating the included angle between the terminal plane and the horizontal plane according to the obtained three-axis data of the gravity sensor comprises:
assuming that the resultant vector of the gravitational acceleration on the X axis and the Y axis is a, and the included angle between the terminal plane and the horizontal plane is b, it can be known from the resultant vector plane diagram of the gravitational acceleration in three axial directions shown in fig. 3: tan b ═ z/a; and is provided with
Thus, there are
Wherein x, y and z are respectively acquired vector force data of the gravity sensor on three axes X, Y, Z.
Step S103, monitoring whether the acceleration of the terminal is continuously changed and whether the acceleration is larger than a second preset threshold value within second preset time, and entering step S104 if the acceleration is continuously changed and the acceleration is larger than the second preset threshold value; otherwise, the process proceeds to step S106.
In this embodiment, the terminal may monitor the acceleration of the terminal in real time through an acceleration sensor built in the terminal, and if it is monitored that the accelerations continuously detected by the acceleration sensor for multiple times within a second preset time always change and the magnitudes of the accelerations detected for multiple times are all greater than a second preset threshold, it is indicated that the terminal may be located on a running vehicle at this time, and the process proceeds to step S104 to continue to determine; otherwise, it indicates that the terminal is not located on the traveling vehicle, i.e., in the off-board navigation state, and the process proceeds directly to step S106.
Step S104, judging whether the variation value of the acceleration direction of the terminal in the second preset time is smaller than a third preset threshold, and if so, entering step S105; otherwise, the process proceeds to step S106.
When the terminal is used for vehicle navigation, the terminal acceleration always faces to a certain direction, because the position of the terminal is always relatively fixed in a vehicle navigation state, and the vehicle always runs relatively straight when running, namely runs up and down, but three axes of an acceleration sensor of the mobile terminal do not change relative to a running 'straight line', and do not change relative to the running direction of the automobile, so the acceleration direction of the acceleration sensor does not change relative to a vehicle chassis. Therefore, in this embodiment, whether the terminal is in the vehicle navigation state may be determined by determining whether a variation value of the terminal acceleration direction within the second preset time is smaller than a third preset threshold, where the acceleration direction is a direction of acceleration resultant of the terminal.
And step S105, determining that the terminal is in a vehicle navigation state.
And step S106, determining that the terminal is in an off-board navigation state.
In this embodiment, if it is determined that the change value of the terminal acceleration direction within the second preset time is smaller than a third preset threshold, it indicates that the terminal is currently in a vehicle navigation state; and otherwise, if the change value of the acceleration direction of the terminal in the second preset time is judged to be larger than or equal to a third preset threshold, the terminal is in the off-board navigation state currently.
Preferably, in another implementation example, after the step S104 determines that the change value of the acceleration direction of the terminal in the second preset time is smaller than a third preset threshold, the method further includes:
monitoring whether navigation software on the terminal is opened;
if the navigation software on the terminal is opened, the step S105 is carried out, and the terminal is determined to be in a vehicle navigation state;
or, monitoring whether the terminal receives the satellite position data;
if the terminal receives the satellite position data, the step S105 is carried out, and the terminal is determined to be in a vehicle navigation state.
Similarly, if it is monitored that the navigation software on the terminal is not opened or the terminal does not receive the satellite position data within a period of time, the terminal is in the off-board navigation state, so that the accuracy of the judgment result can be further improved.
As can be seen from the above, in the monitoring method for the vehicle navigation state provided by this embodiment, whether the terminal is in the non-sleep state is determined; if the terminal plane is in the non-dormant state, monitoring whether the change value of the included angle between the terminal plane and the horizontal plane within first preset time is smaller than a first preset threshold value; if the acceleration is smaller than the first preset threshold, monitoring whether the acceleration of the terminal is continuously changed within second preset time and whether the acceleration is larger than the second preset threshold; if the acceleration is continuously changed and the acceleration is larger than a second preset threshold, judging whether the change value of the acceleration direction of the terminal in the second preset time is smaller than a third preset threshold; if the terminal is smaller than the third preset threshold, the terminal is determined to be in the vehicle-mounted navigation state, so that whether the terminal is in the vehicle-mounted navigation state or not can be accurately judged without depending on a navigation map, scene basis can be provided for other applications on the terminal, service can be better provided for terminal users, and user experience is improved.
Fig. 4 is a schematic flow chart illustrating a method for monitoring a vehicle navigation state according to another embodiment of the present invention. Referring to fig. 4, the method may include the steps of:
step S401, judging whether the terminal is in a non-sleep state, if so, entering step S402; otherwise, the process proceeds to step S406.
Step S402, monitoring whether a change value of an included angle between a terminal plane and a horizontal plane within a first preset time is smaller than a first preset threshold, and if the change value is smaller than the first preset threshold, entering step S403; otherwise, the process proceeds to step S406.
Step S403, monitoring whether the acceleration of the terminal is continuously changed within a second preset time and whether the acceleration is larger than a second preset threshold value; if the acceleration is continuously changed and the magnitude of the acceleration is greater than a second preset threshold, the step S404 is entered; otherwise, the process proceeds to step S406.
Step S404, judging whether the variation value of the acceleration direction of the terminal in the second preset time is smaller than a third preset threshold, and if so, entering step S405; otherwise, the process proceeds to step S406.
And step S405, determining that the terminal is in a vehicle navigation state.
And step S406, determining that the terminal is in an off-board navigation state.
It should be noted that, since the implementation manners of the steps S401 to S406 in this embodiment are completely the same as those of the steps S101 to S106 in the previous embodiment, detailed descriptions thereof are omitted here.
Step S407, counting vehicle navigation time, judging whether the vehicle navigation time exceeds a preset time threshold, and if the vehicle navigation time exceeds the preset time threshold, entering step S408; otherwise, no processing is performed.
In this embodiment, the preset time threshold is a fatigue driving time threshold, and when the vehicle-mounted navigation time exceeds the preset time threshold, it indicates that the current user is driving continuously for a long time and belongs to fatigue driving, and at this time, the step S408 is performed to remind the user.
And step S408, reminding the user of being in a fatigue driving state.
In this embodiment, the user may be reminded of the fatigue driving state in a voice prompt mode in the terminal, such as: the method comprises the steps that voice prompt information of fatigue driving is stored in a terminal in advance, and the voice prompt information is read and played when a user is determined to be in a fatigue driving state; the user can be prompted to be in a fatigue driving state currently through a vibration or ringing alarm mode.
Preferably, after step S408, the method may further include:
step S409, controlling music playing software installed in the terminal to play music of a preset type.
In this embodiment, step S409 specifically includes:
judging the music playing state of music playing software installed in the terminal;
if the music playing software is playing music currently, controlling the music playing software to extract music of a preset type from a music library and add the music to a play list, and playing the music added in the play list;
if the music playing software is in a closed state currently, acquiring a noise value of the current environment of the terminal, and judging whether the noise value is smaller than a preset noise threshold value or not;
if the noise is smaller than the preset noise threshold value, the control terminal automatically starts music playing software, controls the music playing software to extract preset types of music from a music library and add the music into a play list, and plays the music added in the play list.
In this embodiment, if the noise value of the current environment of the terminal is smaller than the preset noise threshold, it indicates that the current user may be in a window-closed driving state, and a fatigue driving state is likely to occur, so that the control terminal automatically starts music playing software to play music of a preset type; if the noise value of the current environment of the terminal is larger than the preset noise threshold value, it indicates that the current environment of the terminal is noisy, for example, the user may be in a windowed driving or a chat by a plurality of people in the vehicle, and at this time, even if the music playing software is turned on, the music effect has little effect on adjusting the fatigue driving state of the user, so that no processing is performed at this time.
Further, in this embodiment, the preset type of music includes, but is not limited to, music of a rock type, a sport type, and the like, which is fast in rhythm and spiritual excitement, so that the occurrence of fatigue of the user can be reduced.
Preferably, in this embodiment, after step S409, the method may further include:
step S410, monitoring whether the temperature of the environment where the terminal is located is higher than a preset temperature threshold value, and if the temperature is higher than the preset temperature threshold value, entering step S411; otherwise, no processing is performed.
And step S411, sending an instruction to the vehicle-mounted machine control system to request to lower the temperature of the air conditioner in the vehicle and increase the ventilation.
Because the user easily enters the sleep state under the condition of high temperature, if the user drives for a long time and the current temperature in the vehicle is high, the user is easily in a state of getting stranded and is not beneficial to driving safety, in the embodiment, the temperature in the vehicle is further monitored, and when the temperature in the vehicle is monitored to be larger than a preset threshold value, the temperature of an air conditioner in the vehicle is controlled to be adjusted downwards by the vehicle control system, and ventilation is increased, so that the user is kept in a waking state, and the occurrence of user fatigue is reduced.
Further, in this embodiment, the terminal establishes wireless communication connection with the car machine control system through bluetooth or wifi in advance, and when detecting that the temperature in the car is higher than the preset temperature threshold value, sends an instruction to the car machine control system of the car through bluetooth connection or wifi connection to make the car machine system adjust the air conditioner temperature down and increase the ventilation according to the received instruction.
Compared with the previous embodiment, the method for monitoring the vehicle navigation state provided by the embodiment can accurately judge whether the terminal is in the vehicle navigation state without depending on a navigation map, provide a scene basis for other applications on the terminal, better serve terminal users, and improve user experience; and moreover, the vehicle-mounted navigation time can be counted according to the judged vehicle-mounted navigation state, corresponding measures are adopted in time when the vehicle is in fatigue driving, the fatigue degree of the user is reduced, and the driving safety of the user is ensured.
