Abstract

A UWB navigation vehicle finding method mainly comprises the following steps that: UWB equipment is installed on a vehicle, and a user uses a mobile phone with a built-in UWB technology to be paired with the UWB equipment installed on the vehicle in advance; the mobile phone UWB of the user automatically records a current position A and communicates with the UWB equipment to test that the distancebetween the current position A of the user and a position C of the vehicle is b meters; the user arrives at a position B after moving for c meters in any direction, and at the moment, the user teststhe distance a meters between the position B and the position C of the vehicle through communication between the mobile phone UWB and the UWB equipment on the vehicle; and the mobile phone of the userautomatically calculates a position of the vehicle according to a formula cos angle CAB=(c2+b2-a2) / 2bc. Compared with the prior art, the UWB navigation vehicle finding method has the beneficial effects that the user uses the UWB in the mobile phone to quickly find the vehicle by arranging the UWB equipment on the vehicle, the difficulty is low, the cost is low, the precision is high, and the application range is wide.

Description

【Technical field】 [0001] The invention relates to the technical field of indoor positioning, in particular to a method for finding a car through UWB navigation. 【Background technique】 [0002] It is very difficult to find a car in an underground parking lot. The existing technology uses UWB base station / Bluetooth to locate the vehicle, and then finds the car through mobile phone navigation. The positioning and transformation are large in scale and high in cost, making it very difficult to realize. [0003] In view of this, it is necessary to provide a method for UWB navigation to find a car to overcome the deficiencies in the prior art. 【Content of invention】 [0004] The purpose of the present invention is to provide a method for finding a car through UWB navigation, aiming at realizing fast car finding, reducing difficulty and cost, and improving accuracy. [0005] In order to achieve the above object, the present invention provides a method for UWB navigation to find ...
