Abstract

This application relates to the field of intelligent hardware, and in particular, to an intelligent scenario in which a mobile terminal and a car are combined. After detecting, by using an acceleration sensor and a gyroscope of the mobile terminal, that a car engine stops, the mobile terminal receives, from a sensor installed near a roof lamp of the car, a signal indicating that the roof lamp is on, and determines that a door of the car is opened. In this case, the mobile terminal sends a reminder to a user.

Claims

1. A method, comprising:

obtaining, by a mobile terminal from a sensor, one or more first values comprising;

Acc_x value comprising a value associated with an x-axis of the sensor

Acc_y value comprising a value associated with an y-axis of the sensor;

or

Acc_z value comprising a value associated with an z-axis of the sensor;

comparing at least one of the one or more first values to one or more thresholds;

in response to the at least one of the one or more first values being less than the one or more thresholds, detecting, by the mobile terminal, that a car stalls or stops;

receiving, by the mobile terminal, a signal indicating that a car lamp is on, and

sending, by the mobile terminal, a reminder to a user.

2. The method according to claim 1, further comprising:

after the mobile terminal detects that the car stalls or stops, instructing, by the mobile terminal, the sensor to detect whether the car lamp is on.

3. The method according to claim 1, wherein the mobile terminal communicates with the sensor via a wireless connection.

4. The method according to claim 1, wherein the reminder comprises:

an indication reminding the user to pay attention to whether there is a pedestrian;

or

an indication of an oncoming car behind when opening the door.

5. The method according to claim 1, wherein the the reminder comprises:

an indication reminding the user to take away an item.

6. The method according to claim 5, wherein the reminder comprises:

an indication a name of the item.

7. The method according to claim 6, wherein the mobile terminal includes a maintainable item reminder list.

8. The method according to claim 1, further comprising determining, by mobile terminal, the reminder according to a positioning result of the mobile terminal, wherein the reminder comprises information related to the positioning result.

9. The method according to claim 8, wherein the reminder comprises an indication of at least one of weather conditions, a security situation, a consumption place, or a recreation place in a current area.

10. The method according to claim 1, further comprising receiving, by the mobile terminal from an acceleration sensor, the Acc_z value of the acceleration sensor on the z-axis;

detecting, by the mobile terminal, via a gyroscope, angle change values of three axes of the gyroscope;

in response to when the Acc_z value in a unit time is less than a threshold, determining, by the mobile terminal that the car stalls.

11. A system, comprising:

a sensor disposed near a car lamp of a car to detect whether the car lamp is on;

a sensor to detect one or more first values comprising;

Acc_x value comprising a value associated with an x-axis of the sensor

Acc_y value comprising a value associated with an y-axis of the sensor;

or

Acc_z value comprising a value associated with an z-axis of the sensor;

a mobile terminal to;

receive, from the sensor, the one or more first values;

compare at least one of the one or more first values to one or more thresholds;

in response to the at least one of the one or more first values being less than the one or more thresholds, detect that a car stalls or stops

send a reminder to a user.

12. The system according to claim 11, wherein

in response to a detection that the car has stalled or stopped, the mobile terminal instructs the sensor to detect whether the car lamp is on.

13. The system according to claim 11, wherein the mobile terminal is connected to the sensor via in a wireless connection.

14. The system according to claim 11, wherein the sensor further:

collects light of the car lamp in a pulse manner;

collects light intensity once every a period of time Δ

T; and

in response to detecting that a change Δ

I of a light intensity value reaches a threshold, determines that the car door is opened and sends the signal to the mobile terminal.

15. The system according to claim 11, wherein the reminder comprises at least one of:

an indication reminding the user to pay attention to whether there is a pedestrian or an oncoming car behind when opening the door;

an indication reminding the user to take away an item that should be carried;

or

an indication a name of an item.

16. The system according to claim 11, wherein the mobile terminal determines the reminder according to a positioning result, and the reminder comprises information related to the positioning result.

17. The system according to claim 11, wherein the mobile terminal comprises a gyroscope;

the mobile terminal receives from an acceleration sensor, the Acc_z value of the acceleration sensor on the z-axis;

the mobile terminal, via the gyroscope, detects angle change values of three axes of the gyroscope;

in response to Acc_z value in a unit time is less than a threshold, determine that the car stalls.

18. A mobile terminal, comprising:

one or more processors; and

a computer readable storage medium storing programming for execution by the one or more processors, the programming including instructions to configure a receiving device to;

obtain, from a sensor, one or more first values comprising;

Acc_x value comprising a value associated with an x-axis of the sensor

Acc_y value comprising a value associated with an y-axis of the sensor;

or

Acc_z value comprising a value associated with an z-axis of the sensor;

compare at least one of the one or more first values to one or more thresholds;

in response to the at least one of the one or more first values being less than the one or more thresholds, detect that a car stalls or stops;

receive, a signal indicating that a car lamp is on; and

send a reminder to a user.
