Example Embodiment

[0019] Example one

[0020] figure 1 This is a schematic flow chart of a method for finding a target vehicle in reverse navigation according to the first embodiment of the present invention. The method can be executed by a device for finding a target vehicle in reverse navigation. The device can be implemented by software and / or hardware as a handheld terminal. A part is built into the handheld terminal. Such as figure 1 As shown, the reverse navigation method for finding a target vehicle provided in this embodiment includes the following operations:

[0021] Step 101: The handheld terminal judges whether the signal strength gradually decreases to a preset signal strength value according to the signal strength after establishing a connection with the vehicle-mounted terminal, and the vehicle-mounted terminal is set in the target vehicle.

[0022] In this embodiment, the handheld terminal may specifically refer to a mobile electronic device such as a mobile phone, a tablet computer, ...

Abstract

The invention discloses a method and a device for searching for a target vehicle through reverse navigation. The method comprises the following steps: a handheld terminal judges whether the signal strength gradually weakens to a preset signal strength value according to the signal strength after connection with a vehicle terminal, wherein the vehicle terminal is arranged in a target vehicle; if the signal strength weakens to the preset signal strength value, the handheld terminal receives and stores data information of the vehicle terminal, and acquires the current position as a starting position; the handheld terminal acquires the walking track of a user from the starting position, and stores the walking track of the user as historical trace information; and the handheld terminal gets the parking position of the target vehicle through reverse navigation according to the historical trace information and the data information of the vehicle terminal. According to the technical scheme adopted by the embodiments of the invention, a user can find a target vehicle reversely without relying on special vehicle search equipment in a parking lot, operation is simple and easy, time is saved effectively for users, and the user experience is enhanced greatly.

Description

technical field [0001] The invention relates to the technical field of navigation and positioning, in particular to a method and device for reverse navigation to find a target vehicle. Background technique [0002] In recent years, with the improvement of people's living standards, automobiles have gradually become popular as a necessary means of transportation for family trips, for people to go to work, shop, and other outing activities, and the storage of vehicles when people go out has also become a necessary link. But with the increasing number of urban buildings, people tend to forget where their cars are parked after shopping and business activities. This problem will be more serious in large parking lots, large shopping malls or underground parking lots in business centers. protrude. [0003] In response to the above problems, the designer has thought of installing a camera or other special equipment in the parking lot to record the user's license plate number and pa...
