Fig. 1 is a block diagram of a vehicle positioning system according to an embodiment of the present invention.

Please refer to FIG. 1, a vehicle positioning system 100 according to an embodiment of the present invention includes a vehicle 110 and a mobile device 120. The mobile device 120 may include an application 121 for obtaining vehicle information of the vehicle 110 and/or controlling functions of the vehicle 110. The mobile device 120 may also include a GPS module 122 (ie, a global positioning system module). The GPS module 122 can receive data of the application 121 and send positioning information to the application 121. The vehicle 110 and the mobile device 120 can communicate through any wireless communication protocol. For example, the vehicle 110 and the mobile device 120 may perform Bluetooth pairing and communicate with each other through the Bluetooth communication protocol. Both the vehicle 110 and the mobile device 120 may have a communication chip (not shown in the figure) and a processor (not shown in the figure).

When the user holding the mobile device 120 approaches the vehicle 110, the mobile device 120 can establish communication with the vehicle 110, such as establishing a Bluetooth connection. The mobile device 120 can receive the time interval and the minimum displacement. In one embodiment, the time interval and the minimum displacement can be set by the application code of the mobile device 120. Specifically, the mobile device 120 can execute application code to set the time interval corresponding to the shortest updateable positioning time and the minimum displacement corresponding to the minimum updateable distance range, and transmit the time interval and the minimum displacement to the mobile device 120 The GPS module 122, but the invention is not limited to this. In another embodiment, the user can also input the time interval corresponding to the shortest updateable positioning time and the minimum displacement corresponding to the minimum updateable distance range through the application 121. For example, when the user input time interval is 10 seconds and the minimum displacement is 10 meters, the application 121 will be more than 10 seconds away from the last updated position and the vehicle 110 will be more than 10 meters away from the last updated position At this time, the location of the vehicle 110 is updated. In other words, the application 121 of the mobile device 120 The first position (that is, the last updated position) is obtained at the first time point (that is, the time point when the position was last updated). When the difference between the second time point and the first time point is greater than the time interval and the distance between the second position and the first position is greater than the minimum displacement, the application 121 is at the second time point (that is, the time point of this update) Get the second position (that is, the position updated this time). This can reduce the power consumption caused by periodic or continuous positioning. It is worth noting that the time interval and minimum displacement settings can be set after the mobile device 120 and the vehicle 110 have established communication or when the mobile device 120 and the vehicle 110 have not yet established communication, whether they are set by the application code or the user. Make settings.

When the application 121 receives the time interval and the minimum displacement, the application 121 transmits the minimum displacement and/or time interval to the GPS module 122. After the GPS module 122 receives the minimum displacement and/or time interval, only when the above-mentioned "the difference between the second time point and the first time point is greater than the time interval" and "the distance between the second position and the first position is greater than the minimum displacement" When the two conditions are met at the same time, positioning information (for example, the first position and the second position) will be sent to the application 121. The above operations can be completed by the GPS module 122 in cooperation with the timer of the mobile device 120. Therefore, when the GPS module 122 determines that the distance between the third position and the first position is less than the minimum displacement, the GPS module 122 will not transmit the third position to the application 121. Through the aforementioned vehicle positioning method, the mobile device 120 will only locate the vehicle 110 when certain conditions are met, so that the power consumption of the mobile device 120 due to frequent positioning can be effectively reduced.

Although in the above embodiment, it is described that the GPS module 122 has "the difference between the second time point and the first time point is greater than the time interval" and "the difference between the second position and the first position" When the two conditions are greater than the minimum displacement, the positioning information is sent to the application 121 when the two conditions are met. In another embodiment, the GPS module 122 can also be used when the difference between the second time point and the first time point is greater than or equal to the time When the two conditions of "interval" and "the distance between the second position and the first position are greater than or equal to the minimum displacement" are met simultaneously, the positioning information is sent to the application 121.

In one embodiment, when the communication between the mobile device 120 and the vehicle 110 is disconnected, the application 121 uses the last updated location information as the last parking location of the vehicle 110. For example, when the Bluetooth communication between the mobile device 120 and the vehicle 110 is disconnected, the application 121 will obtain the latest updated location information as the last parking location record of the vehicle 110.

In one embodiment, the mobile device 120 receives the vehicle speed from the vehicle 110. When the vehicle speed is zero, the application 121 periodically (e.g., every 100 seconds) obtains the last updated location information, and the latest updated location information Displayed on the user interface of the application 121. In this way, it can be avoided that when the user stops at a red light or the vehicle 110 is stationary for a period of time, the application 121 does not update the position of the vehicle 110 for a long time because the vehicle displacement during this period of time is less than the minimum displacement.

Fig. 2 is a flowchart of a vehicle positioning method according to an embodiment of the present invention.

Referring to FIG. 2, in step S201, communication with the vehicle is established by the mobile device.

In step S202, the mobile device receives the time interval and the minimum displacement.

In step S203, the first position is obtained at the first time point by the application of the mobile device.

In step S204, when the difference between the second time point and the first time point is greater than the time interval and the distance between the second position and the first position is greater than the minimum displacement, the second position is obtained at the second time point by the application program .

In step S205, when the communication between the mobile device and the vehicle is disconnected, the application program uses the last updated location information as the last parking location of the vehicle.

To sum up, the vehicle positioning system, vehicle positioning method, and mobile device of the present invention will first establish communication between the mobile device and the vehicle and receive the time interval and minimum displacement. The application gets the first position at the first point in time. When the difference between the second time point and the first time point is greater than the time interval and the distance between the second position and the first position is greater than the minimum displacement, the application program obtains the second position at the second time point. In this way, the power consumption of the mobile device's positioning function of the vehicle can be effectively saved.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be determined by the scope of the attached patent application.
