VEHICLE NAVIGATION SYSTEM FOR PARKING ZONE USING LOW-POWER RADIO STATIONS AND METHOD OF SUCH NAVIGATION Russian patent published in 2020 - IPC G08G1/00 G08G1/14 G06K9/00 H04N7/18 B60R21/00 

FIELD: vehicle navigation system.

SUBSTANCE: navigation system for parking zone comprises multiple parking zone units. Each node comprises a camera, a low-power radio station, a cellular device, wherein each of the parking requests and the walking destination from the user is input on the cellular device, and a parking assistance server in communication with nodes and a cellular device. Server analyzes parking zone images captured by cameras, receives a parking request from a cellular device in response to said request, sends a proposed parking location from a parking location to a user, provides the vehicle arrival sequence along the trajectory points. Each of the trajectory points additionally contains a fixed value of the signal strength for the intensity of radio signals in the location of the trajectory point and a fixed time value for relative timing of radio signals in the location of the trajectory point and outputs the vehicle arrival sequence along the motion path points leading from the proposed parking place to the walking destination point.

EFFECT: higher efficiency of searching for free parking places.
