Embodiment Construction

[0036] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0037] The present invention proposes an intelligent reverse car-finding method, such as figure 1 shown, including the following steps:

[0038] Step 1, the wireless signal broadcasting device installed in the vehicle being searched sends broadcast frames to the surroundings;

[0039] Step 2, when the wireless signal receiving module in the car-finding device receives the above-mentioned broadcast frame, calculate the distance between the searched vehicle and the car-finding device according to the signal strength of the broadcast frame.

[0040] The car finding device includes a wireless signal receiving module, a gyroscope and a gyroscope ...

Abstract

A smart vehicle backtracking method comprises: broadcasting, by a radio signal broadcast apparatus arranged at a vehicle to be found, and at a fixed time interval, a broadcast frame; upon a vehicle tracking device receiving the broadcast frame, correcting, according to accelerations of a gyroscope along x, y, and z axes, a received signal strength indicator (RSSI) of the broadcast frame, and performing three-point smoothing; in order to reduce fluctuation of RSSI, performing, repeatedly and according to the accelerations of the gyroscope, operations of the acceleration correction and three-point smoothing processes; and computing, according the corrected received signal strength indicator RSSInew, a distance between the vehicle tracking device and the vehicle to be found. As a result, the smart reverse vehicle tracking method is employed to increase precision of vehicle positioning.

Description

technical field [0001] The invention relates to the field of intelligent positioning of vehicles, in particular to an intelligent reverse vehicle search method. Background technique [0002] When the vehicle needs services such as driving, towing, battery replacement, etc., after the staff arrives at the approximate location designated by the driver, they often cannot quickly and accurately find the vehicle that needs service because of the large number of surrounding vehicles. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention proposes an intelligent reverse car-finding method, which improves the accuracy of distance estimation. [0004] The present invention proposes a kind of intelligent reverse car search method, comprises the following steps: [0005] Step 1, the wireless signal broadcasting device installed in the vehicle being searched sends broadcast frames to the surroundings; [0006] Step 2...
