Abstract

The present disclosure provides an automatic positioning system that is in a mobile device. The mobile device communicates with a vehicle. The system includes a first detection module, a second detection module and a positioning module. The first detection module detects the mobile device is in a moving state or a static state in real-time. The second detection module detects the vehicle is in a moving state or a static state in real-time. The positioning module acquires the location of the mobile device and records the acquired location as a position where the vehicle is parked in the mobile device, when the vehicle changes from the moving state to the static state, the mobile device changes from the static state to the moving state.

Claims

1. An automatic positioning system in a mobile device, the mobile device communicating with a vehicle via a wireless network, the automatic positioning system comprising:

a first detection module that detects a motion state of the mobile device to determine if the mobile device is in a moving state or a static state in real-time;

a second detection module that detects a motion state of the vehicle to determine if the vehicle is in a moving state or a static state in real-time;

a positioning module that acquires the location of the mobile device and records the acquired location as a position of the vehicle in the mobile device, under a condition that the second detecting module determines the vehicle changes from a moving state to a static state and the first detecting module determines the mobile device changes from a static state to a moving state;

a navigation module that acquires a current location of the mobile device as a starting point, reads the recorded position as an ending point, and calculates a path from the starting point to the ending point; and

the navigation module displays the calculated path on the electronic map as a color line.

2. The automatic positioning system according to claim 1, wherein the mobile device further comprises an electronic map, the positioning module marks the acquired location on the electronic map, and the navigation module shows the calculated path on the electronic map.

3. The automatic positioning system according to claim 2, wherein the navigation module guides the user to the vehicle by voice.

4. The automatic positioning system according to claim 1, wherein the mobile device further comprises a first detection unit, the first detection module detects a current speed of the mobile device through the first detection unit, and determines if the mobile device is in a moving state or a static state according to the detected speed.

5. The automatic positioning system according to claim 4, wherein the first detection unit is a speed sensor.

6. The automatic positioning system according to claim 1, wherein the mobile device further comprises a second detection unit, the second detection module sends a state detecting command to the vehicle to detect a current speed of the vehicle through the second detection unit, and determines if the vehicle is in a moving state or a static state according to the detected speed.

7. The automatic positioning system according to claim 6, wherein the second detection unit is a speed sensor.

8. An automatic positioning method implemented by a mobile device, the mobile device communicating with a vehicle via a wireless network, the mobile device comprising a first speed sensor and a second speed sensor, the method comprising:

detecting a current speed of the mobile device by the first speed sensor to determine if the mobile device is in a moving state or a static state in real-time;

sending a state detecting command to the vehicle and detecting a current speed of the vehicle by the second speed sensor and determine if the vehicle is in a moving state or a static state in real-time according to the detected speed;

acquiring the location of the mobile device and records the acquired location as a position of the vehicle, under a condition that the second detecting module determines the vehicle changes from a moving state to a static state and the first detecting module determines the mobile device changes from a static state to a moving state;

acquiring a current location of the mobile device as a starting point, reading the recorded position as an ending point, and calculating a path from the starting point to the ending point; and

displaying the calculated path on the electronic map as a color line.

9. The method according to claim 8, wherein the mobile device further comprises an electronic map, and localization further comprises:

marking the acquired location on the electronic map; and

showing the calculated path on the electronic map.

10. The method according to claim 9, wherein navigation further comprises:

guiding the user to the vehicle by voice.
