Intelligent vehicle-mounted terminal OBU integrating ETC and V2X functions and application

Abstract

An intelligent vehicle-mounted terminal OBU integrating ETC and V2X functions is installed on a front windshield of a vehicle and comprises a shell and two main boards, the two main boards are arranged in the shell and integrated with an ETC module and a V2X module respectively, the ETC module and the V2X module are connected through an internal connection module, and the ETC module and the V2X module are independent of each other and do not perform data interaction; an external connection module, an LED indicating lamp and a reset key are arranged on the shell. According to the invention, the number and cost of in-vehicle equipment installation are saved, the communication modes are diversified, and the application range is wide; the antenna is built in and is not connected to a CAN bus, so that the equipment is light and miniaturized; according to the actual environment condition, the ETC service requirement can be met, the method can also be used for C-V2X vehicle-road cooperation scene application, the information service level of a vehicle end user is greatly improved, and the road traffic safety and the passing efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of intelligent network-connected vehicle communication, in particular to an intelligent vehicle-mounted terminal OBU integrating ETC and V2X functions and its application. Background technique [0002] ETC (Electronic Tolling Collection, electronic toll collection system) integrates "vehicle identification" and "electronic payment", based on DSRC (Dedicated Short Range Communications) technology in the 5.8GHz microwave band, through RSU (Road Side Unit, roadside unit) and the on-board OBU (On Board Unit) with ETC function, collect the identity information of passing vehicles, accurately split the expressway toll and automatically collect the information from the bound IC card (Integrated Circuit Card, integrated circuit card) or debit the corresponding funds from the bank account. With the country's intensive introduction of policies to vigorously promote the construction of expressway ETC gantry systems, a...
