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;

    a transmitting unit that transmits the generated used-distance information;

    a vehicle-state detecting unit that detects a vehicle state of at least one of a speed, an angular speed, and an acceleration; and

    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 passing-confirmation information that is outwardly transmitted by the in-vehicle unit when the vehicle passes an electronic toll collection gate,wherein the used-distance information generating unit generates the used-distance information relating to a used distance used from the designated entrance to the designated exit, andwherein, in a case where the in-vehicle unit outwardly does not transmit passing-confirmation information relating to passing an electronic toll collection gate corresponding to an exit of the toll road at a certain toll-road use occasion, the transmitting unit transmits used-distance information relating to a used distance of the toll road that the vehicle uses at the certain toll-road use occasion when a toll is paid by using the in-vehicle unit at a toll-road use occasion subsequent to the certain toll-road use occasion.
