  The ETC vehicle-mounted device 2 includes an antenna unit 2a, a transceiver unit 2b, a modem unit 2c, an ETC control processing unit 2d, a human machine interface unit (HMI / F) 2e, a security module unit (ETC-SAM) 2f, and an IC card interface. The unit 2g and the power source unit 2h are included.

  The antenna unit 2 a transmits and receives radio waves of a dedicated short range communication (DSRC) method to and from the road device 1. The transceiver 2b receives the RF signal from the antenna unit 2a and sends it to the modem unit 2c, and also receives the ASK modulation signal from the modem unit 2c and sends it to the antenna unit 2a. The modem unit 2c demodulates the RF signal sent from the transmitting / receiving unit 2b and sends it to the ETC control processing unit 2d, and ASK-modulates the data sent from the ETC control processing unit 2d and sends it to the sending / receiving unit 2b. The ETC control processing unit 2d processes information included in the demodulated signal sent from the modem unit 2c, transmits display data to the HMI / F 2e, and is extracted via the IC card interface unit 2g to obtain an ETC-SAM 2f. The ETC information recorded in the IC card (not shown) encrypted in (1) is acquired and transmitted to the modem unit 2c. The HMI / F2e provides an interface for notifying the user of various information related to ETC. The ETC-SAM 2f performs mutual authentication with the roadside device 1 and the IC card, data encryption, and the like.

  The meter device 3 includes a meter-side control processing unit 3a made of a microcomputer or the like, a display 3b made of a liquid crystal display, and a meter 3c made of a speed meter for instructing traveling information. The display 3b displays an od / trip meter display and other travel assistance information, and also displays an ETC travel distance as will be described later.

  In such a configuration, the travel distance display process performed by the meter-side control processing unit 3a will be described with reference to the flowchart of FIG.

  First, the meter side control processing unit 3a determines whether or not it has passed through the entrance gate (step S1). This determination is performed as follows. That is, when the vehicle enters a toll road such as an expressway, the entrance gate information transmitted from the road device 1 installed at the toll road entrance gate is received by the ETC vehicle-mounted device 2, and the meter device 3 is connected via the HMI / F 2e. It is transmitted to the meter side control processing unit 3a. When this entrance gate information is received, the meter-side control processing unit 3a determines that the vehicle has passed the toll road entrance gate.

  Next, the meter-side control processing unit 3a sets the timer using the received entrance gate information as a trigger, and sets the time at that time and the travel distance of the odometer in the internal memory which is a storage means (step S2). Next, the meter-side control processing unit 3a calculates the travel distance from the entrance gate while traveling on the toll road by subtracting the set odometer travel distance from the current odometer travel distance. The travel distance during the use of the ETC (hereinafter referred to as ETC travel distance) is displayed on the display 3b (step S3).

  Next, the meter side control processing unit 3a determines whether or not it has passed through the exit gate (step S4). This determination is performed as follows. That is, when the vehicle leaves the toll road, the exit gate information transmitted from the on-road equipment 1 installed at the toll road exit gate is received by the ETC vehicle-mounted device 2, and the meter side control processing of the meter equipment 3 via the HMI / F 2e. Is transmitted to the unit 3a. When this exit gate information is received, the meter-side control processing unit 3a determines that it has passed the toll road exit gate.

  Next, the meter-side control processing unit 3a uses the received exit gate information as a trigger to reset the timer and to reset the odometer travel distance stored in the internal memory (step S5).

  FIG. 3 is a front view showing a configuration example of the meter device 3 in the vehicle. The meter device 3 is a combination meter including a plurality of meters, for example, and a display 3b such as a liquid crystal display is provided between two analog meters 3c such as a speedometer and a tachometer. The ETC mileage is displayed.

  FIG. 4 is a diagram showing a display example of the ETC travel distance displayed on the display 3b. In this display example, it is indicated that the ETC travel distance is currently 85 km.

  In this manner, by displaying the ETC information on the display 3b in the meter device 3, an ETC in-vehicle device display or a car navigation display is not required. In addition, when using a fee discount system according to the ETC's travel distance, as a guideline whether the travel distance displayed on the display 3b to the target interchange (ETC exit gate) is applicable. Can be used. In addition, the time data can be saved from the information acquired when passing through the ETC exit gate, and displayed appropriately, so that it can be used for confirming whether it is the target time for a fee discount system or the like.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this, A various deformation | transformation and application are possible.

  For example, the display of the ETC travel distance on the display 3b can be displayed at the same time as the odd and / or trip meter display or by switching under the control of the meter side control processing unit 3a. Moreover, when passing through a toll road entrance gate, you may comprise so that it may display on the indicator 3b automatically.

  In addition, since the travel time on the toll road from gate-in to gate-out is measured by a timer, the average vehicle speed can be calculated by dividing the travel distance from gate-in to gate-out by the travel time described above. You may display the driving time on a toll road, an average vehicle speed, etc. to 3b.

  Further, when traveling on a plurality of toll roads, ETC travel distance data from the entrance gate to the exit gate of each toll road may be stored in the internal memory.
