Abstract

The invention discloses a positioning method and system applied to an electronic toll collection system and a storage medium, the electronic toll collection system comprises a vehicle-mounted unit and a roadside unit, the vehicle-mounted unit is arranged on a vehicle, and the positioning method applied to the electronic toll collection system comprises the steps of obtaining first positioning information and second positioning information, the first positioning information comprises vehicle GPS position information of the vehicle-mounted unit, vehicle running speed information and height information of the vehicle-mounted unit; the second positioning information comprises GPS position information of the roadside unit, microwave positioning information of the roadside unit and height information of the roadside unit; and the position information of the vehicle is determined according to the first positioning information and the second positioning information, so that the problem of large vehicle positioning error in the electronic toll collection system due to the difference of the installation environments of the roadside units and the characteristics of microwave signal reflection is solved, and the position precision of vehicle positioning in the electronic toll collection system is improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a positioning method, a system and a storage medium applied to an electronic non-stop charging system. Background technique [0002] The electronic non-stop toll collection system (referred to as ETC) is an automatic toll collection for expressways or bridges. Through the dedicated short-range communication between the on-board electronic tag installed on the vehicle windshield and the microwave antenna on the ETC lane of the toll station, the computer networking technology is used to carry out background settlement processing with the bank, so that the vehicle can pass through the highway or bridge. The purpose of paying highway or bridge tolls without stopping at the station. [0003] The electronic toll collection system includes a roadside unit (RSU for short), an on-board unit (OBU for short), and a toll unit. The roadside unit communicates wi...
