Device and system for toll payment
First Claim
1. A toll payment device that is provided in a vehicle for paying a toll at an electronic toll collection gate that the vehicle passes when using a toll road, and is able to receive a partial payback of the paid toll based on a used distance that is used on the toll road, the toll payment device comprising:
- an in-vehicle unit that automatically pays a toll by communications with a roadside unit disposed at the electronic toll collection gate;
a road data storing unit that stores road data including position information of the toll road;
a position detector that detects a current position of the vehicle;
a used-distance information generating unit that generates used-distance information relating to a used distance of the toll road that the vehicle uses, based on the detected current position and the stored road data; and
a transmitting unit that transmits the generated used-distance information.

Abstract
A navigation device stores road data that includes positions of toll roads where payback of a part of a toll is provided based on a used distance of each of the toll roads. The navigation device computes a traveled distance of the relevant toll road to thereby compute the used distance of the toll road based on the computed traveled distance. Thus, the used distance of a toll road can be accurately computed, even when a vehicle travels a loop line within the toll road by multiple circles. Information that relates to the payback and includes the used distance of the toll road is then transmitted to a center to thereby receive a partial payback of the toll.

14. A toll payment system for a vehicle executing, at an electronic toll collection gate that the vehicle passes when using a toll road, a toll payment for paying a toll for the toll road where a payback of a part of the paid toll is able to be received based on a used distance that is used on the toll road, the toll payment system comprising:
-
a toll payment device that is provided in the vehicle and includes an in-vehicle unit that automatically pays a toll by communications with a roadside unit disposed at the electronic toll collection gate and outwardly transmits passing-confirmation information when the vehicle passes an electronic toll collection gate, a road data storing unit that stores road data including position information of the toll road, a position detector that detects a current position of the vehicle, a vehicle-state detecting unit that detects a vehicle state of at least one of a speed, an angular speed, and an acceleration, an entrance and exit designating unit that designates an entrance and an exit where the vehicle starts and ends a use of the toll road, respectively, based on at least one of the detected vehicle state and the passing-confirmation information that is outwardly transmitted by the in-vehicle unit, a used-distance information generating unit that generates used-distance information relating to a used distance of the toll road that the vehicle uses from the designated entrance to the designated exit, based on the detected current position and the stored road data, and a transmitting unit that transmits the generated used-distance information; and
a center that includes a processing unit that interfaces with the roadside unit and executes via the roadside unit a process relating to the payback when the used-distance information is received via the roadside unit in addition to a process relating to the toll payment. - View Dependent Claims (15, 16, 17, 18, 19)
