Problems solved by technology

However, the staff at the exit toll booths have a lot of work to do, such as receiving road tickets / issuing receipts, collecting tolls, and the work is very intense
Therefore, there has been a problem so far that when the number of vehicles using the expressway increases, traffic is congested near the exit
[0009] If a high-efficiency processor (CPU) is loaded in the vehicle-mounted unit, it is possible for the vehicle-mounted unit to carry out communication processing with the second antenna in parallel while performing write processing on the IC card. it's going to be expensive

Embodiment Construction

[0035] Preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0036] Such as figure 1 As shown, an ETC system generally includes a roadside device 1 installed at a toll booth, an on-board unit 3 mounted on a vehicle for wireless communication with the roadside device 1, and a detachably installed on-board unit 3 IC card 5 for reading / writing information. The wireless communication speed between the roadside device 1 and the vehicle-mounted unit 3 is relatively high in order to exchange information stored in their internal buffer memories. On the contrary, there is a refresh memory inside the IC card 5, and the vehicle-mounted unit 3 writes or reads information into the refresh memory. Therefore, the speed at which information is written into the IC card 5 is especially lower than the communication speed between the roadside device 1 and the vehicle-mounted unit 3 .

[0037] Such as figure 2 As shown in , the roads...

Abstract

The present invention provides a toll collection system to collect tolls by way of wireless communication between an onboard unit that is loaded on a vehicle and stacks an IC card and a gate equipment that is installed at a tollgate. The gate equipment sends information showing the presence or the number of wireless communication equipment installed at the latter stage through the wireless communication to the onboard unit, which in turn causes the writing process on an IC card after executing the communication with all of the wireless communication equipment of the gate equipment.

Description

technical field [0001] The present invention relates to a charging system for charging vehicles on a toll road such as an expressway through wireless communication, an on-board unit mounted on a vehicle that can use the charging system, and a charging method. technical background [0002] Among conventional toll collection systems for accurately calculating tolls on toll roads, there is a magnetic card type toll collection system using road tickets, prepaid cards, cash cards, or cash money. [0003] In this magnetic card toll collection system, the magnetic card that records the information at the entrance, that is, indicates which entrance the vehicle enters from, is issued to the vehicle entering the entrance in the form of a road ticket, and the driver needs to carry this Ticket to move forward. At the exit, the road ticket carrying the information of the entrance is read out by the driver, and the toll is calculated. The calculated total is displayed to the driver, and...
