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 reminding method, comprising:

detecting, by a mobile terminal, that a car stalls or stops;

receiving, by the mobile terminal from a sensor, a signal indicating that a car lamp is on, wherein the car lamp is on when a door of the car is opened, and the sensor is configured to detect whether the 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 receives the signal from the sensor in a wireless manner.

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

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

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

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

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

further pointing out to the user a name of the item that should be carried specifically.

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

8. The method according to claim 1, wherein the mobile terminal determines the content of the reminder according to a positioning result of the mobile terminal, and the content of the reminder comprises information related to the positioning result.

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

10. The method according to claim 1, wherein the mobile terminal uses an acceleration sensor to obtain, by means of energy detection, values Acc_x, Accy, and Acc_z of an x-axis, a y-axis, and a z-axis of the acceleration sensor, and when energy of Acc_z in a unit time is less than a threshold Wz, determines that the car stalls;

or when energy of Acc_x or Acc_y in a unit time is less than a threshold Wx or Wy, determines that the car stops.

11. The method according to claim 1, wherein the mobile terminal uses an acceleration sensor to obtain, by means of energy detection, a value Acc_z of the acceleration sensor on the z-axis, uses a gyroscope to detect angle change values of three axes of the gyroscope, and when energy of the value Acc_z of the acceleration sensor on the z-axis in a unit time is less than a threshold Wz, determines that the car stalls;

or when all the angle change values, detected by the gyroscope, of the three axes in a unit time are less than a threshold, determines that the car stops.

12. A car reminding system, comprising:

a sensor, disposed near a car lamp of a car and configured to detect whether the car lamp is on, wherein the car lamp is on when a door of the car is opened; and

a mobile terminal, configured to receive, from the sensor and after detecting that the car stalls or stops, a signal indicating that the car lamp is on, and send a reminder to a user.

13. The system according to claim 12, wherein

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

14. The system according to claim 12, wherein the mobile terminal is connected to the sensor in a wireless manner and receives the signal from the sensor.

15. The system according to claim 12, wherein the sensor collects light of the car lamp in a pulse manner, collects light intensity once every a period of time Δ

T, and once 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.

16. The system according to claim 12, wherein content of the reminder comprises any one of:

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

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

further pointing out to the user a name of the item that should be carried specifically.

20. The system according to claim 12, wherein the mobile terminal determines the content of the reminder according to a positioning result of the mobile terminal, and the content of the reminder comprises information related to the positioning result.

22. The system according to claim 12, wherein the mobile terminal has an acceleration sensor, uses the acceleration sensor to obtain, by means of energy detection, values Acc_x, Accy, and Acc_z of an x-axis, a y-axis, and a z-axis of the acceleration sensor, and when energy of Acc_z in a unit time is less than a threshold Wz, determines that the car stalls;

or when energy of Acc_x or Acc_y in a unit time is less than a threshold Wx or Wy, determines that the car stops.

23. The system according to claim 12, wherein the mobile terminal further has a gyroscope, the mobile terminal uses an acceleration sensor to obtain, by means of energy detection, a value Acc_z of the acceleration sensor on the z-axis, uses the gyroscope to detect angle change values of three axes of the gyroscope, and when energy of the value Acc_z of the acceleration sensor on the z-axis in a unit time is less than a threshold Wz, determines that the car stalls;

or when all the angle change values, detected by the gyroscope, of the three axes in a unit time are less than a threshold, determines that the car stops.

17-19. -19. (canceled)

21. (canceled)

24. 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 the receiving device to configured to;

detect a car stalls or stops;

after detecting that the car stalls or stops, receive a signal indicating that the car lamp is on from a sensor; and

send a reminder to a user.
