However, in the traveling speed management method described above, it is necessary to provide an operation result collection device and a GPS device in the vehicle, and these devices are expensive, and thus require a lot of costs.
The present invention is intended to solve such problems, and an object of the present invention is to provide a method for managing the traveling speed of a vehicle at low cost and easily.

The present invention is for achieving the above object, and is configured as follows.
The invention according to claim 1 is a method of managing the traveling speed of the vehicle by an ETC on-board device mounted on the vehicle, wherein the ETC on-board device passes through a first gate provided on a predetermined road.

The ETC on-vehicle device detects the average speed of the vehicle from the distance between the gates of the first gate and the second gate and the time difference between the passage times of the first gate and the second gate. It is the structure including the step to calculate. Therefore, for example, if you are driving on an expressway, the ETC on-board unit is located between the gates of the interchange entrance gate (first gate) entering the expressway and the interchange exit gate (second gate) exiting the expressway. The ETC vehicle-mounted device can detect the passing times of both gates and calculate the average speed between the gates based on the time difference. Therefore, if the vehicle is equipped with an ETC vehicle-mounted device, the average speed of the vehicle when traveling on a highway can be easily calculated at low cost.

Each distance to the reference point is stored in advance, and the distance between the first gate and the second gate is calculated based on the difference between the distances. For this reason, ETC on-board equipment is a highway equipped with a plurality of interchanges. For example, if the first interchange is used as a reference point and each distance from the reference point to each interchange is memorized, it can be used between any two interchanges. The distance can be calculated by subtracting the distance from each interchange to the reference point. Therefore, when storing the distance between any two interchanges, it is not necessary to store all combinations.

  Invention of Claim 3 is the traveling speed management method of Claim 1, Comprising: The said ETC onboard equipment has memorize | stored beforehand the distance between the adjacent gates in all the gates of the said predetermined road. The method includes a step of calculating a distance between both the first gate and the second gate by a sum of distances between the adjacent gates. For this reason, ETC on-board equipment can store the distance between any two interchanges on an expressway with a plurality of interchanges, and the distance between any two interchanges. It can be calculated from the sum of distances between changes. Therefore, when storing the distance between any two interchanges, it is not necessary to store all combinations.

  Invention of Claim 4 is the driving speed management method of any one of Claims 1-3, Comprising: The said ETC onboard equipment identified and calculated the driver who drives the said vehicle. And a step of associating the identified driver with the average speed of the vehicle. Therefore, the ETC vehicle-mounted device can associate the identified driver with the calculated average speed. Therefore, for example, even if a transportation company is configured such that a plurality of drivers drive a single truck, the transportation company can calculate and manage the average speed of the trucks that are driven for each driver.

  The invention according to claim 5 is the traveling speed management method according to claim 4, wherein the ETC vehicle-mounted device includes an output unit, and outputs at least one of an average speed of the vehicle or a driver of the vehicle. And a step of outputting from the means. Therefore, the ETC on-board device can output the calculated average speed by printing. Therefore, for example, if applied to a shipping company, each driver can submit the average speed printed with the delivery slip etc. to the driver each time the delivery is completed, and the submitted average speed exceeds the legal speed. If you do this, you can instantly pay attention to the driver.

Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS.
FIG. 1 is a configuration diagram of each device of the ETC system. FIG. 2 is a block diagram showing an internal configuration of the ETC vehicle-mounted device 30 mounted on the vehicle 1 shown in FIG. The traveling speed management method of the present invention manages the traveling speed of the vehicle 1 by using an ETC system that is well known and installed on a highway or the like, and an ETC vehicle-mounted device 30 corresponding to the ETC system. Is the method. First, the ETC system and the ETC vehicle-mounted device 30 will be described in detail with reference to FIGS. The “highway 10”, “interchange entrance gate 12 of the highway 10”, and “interchange exit gate 14 of the highway 10” described in this embodiment are the “predetermined road”, “ It corresponds to “first gate” and “second gate”, respectively. “Interchange” is hereinafter referred to as “IC”.

  First, as shown in FIG. 1, an entrance gate 12 is provided on an approach road 11 when the vehicle 1 enters an expressway 10 from a general road. The entrance gate 12 is provided with an entrance antenna 12a. An ETC vehicle-mounted device 30 (not shown in FIG. 1) mounted on the vehicle 1 and a control device 12b (provided on the entrance gate 12) are provided via the entrance antenna 12a. (Not shown in FIG. 1) can be communicated in a non-contact manner.

  Conversely, an exit gate 14 is provided on the exit road 13 when the vehicle 1 exits from the highway 10 to a general road. The exit gate 14 is provided with an exit antenna 14a. An ETC vehicle-mounted device 30 mounted on the vehicle 1 and a control device 14b (not shown in FIG. 1) provided on the exit gate 14 are provided via the exit antenna 14a. Can communicate without contact.

  Next, the ETC vehicle-mounted device 30 will be described with reference to FIG. The ETC vehicle-mounted device 30 includes a control unit 31, a reception unit 32 connected to the control unit 31, a time identification unit 33, a driver identification unit 34, a transmission unit 35, a storage unit (RAM, ROM) 36, and an output unit 37. And is mainly composed. The control means 31 receives predetermined information from the antennas 12a and 14a via the reception means 32 and the transmission means 35 and stores them in the storage means 36, and also stores the information stored in the storage means 36 in the exit antenna 14a. The function to send is executed.

  The control unit 31 can recognize the current time by the time identification unit 37, recognize the driver by the driver identification unit 34, and store the recognized information in the storage unit 36. The driver identifying means 34 is, for example, an ID card reading means. The driver 31 is stored in advance in the ID card, and the control means 31 can identify the driver by reading the ID card. The storage unit 36 stores a distance database 40 indicating the distance from the reference point to each gate, details of which will be described later. Further, the output unit 37 (for example, a printing apparatus) can output (print) each piece of information stored in the storage unit 36 in association with the current time.

  Therefore, when the vehicle 1 equipped with the ETC vehicle-mounted device 30 passes through the entrance gate 12 when entering the highway 10, the vehicle 1 receives IC identification information that can identify the entrance IC from the control device 12b via the entrance antenna 12a. And stored in the storage means 36. The IC identification information is information that can identify which IC is based on the identification information by assigning different identification information to each IC, for example. For example, “1” is assigned as IC identification information for “A1” IC, and “2” is assigned in advance as IC identification information for “A2” IC.

  Thereafter, when the vehicle 1 passes through the exit gate 14 when leaving the highway 10, the control means 31 transmits the IC identification information of the entrance IC stored in the storage means 36 to the control device 14b via the exit antenna 14a. . And the control apparatus 14b calculates a toll from the received IC identification information, and transmits the toll to the ETC onboard equipment 30 of this vehicle 1. The user pays the toll calculated in this way to the operating company of the expressway 10 by a predetermined payment method (for example, card withdrawal).

  Next, the traveling speed management method of the present invention using the above-described ETC system and ETC vehicle-mounted device 30 will be described with reference to FIG. FIG. 3A is a diagram illustrating the highway 10. FIG. 3B is a diagram for explaining the distance database 40 of the expressway 10 shown in FIG. FIG. 3C is a diagram for explaining the IC / time identification information 50.

  The storage means 36 of the ETC on-vehicle device 30 stores a distance database 40 shown in FIG. The distance database 40 stores, for example, the distance from the reference point to each IC, with “A1” IC of the highway 10 as a reference point. In the figure, the distance from the reference point to “A2” IC is 30 km, the distance from the reference point to “A3” IC is 50 km,..., The distance from the reference point to “A10” IC is 300 km, ..., the distance from the reference point to the “A1” IC is 450 km. Therefore, if the control means 31 can recognize the IC identification information of the entrance IC and the exit IC, the distance between these ICs can be calculated by comparing and subtracting against the distance database 40.

  When the vehicle 1 passes through the entrance gate 12 of the “A10” IC, it receives the IC identification information “10” from the entrance antenna 12 a and stores it in the storage unit 36 in association with the current time from the time identification means 33. . Similarly, when traveling on the highway 10 and passing through the exit gate 14 of the “A16” IC, the IC identification information “16” is received from the exit antenna 14 a and associated with the current time from the time identification means 33. Store in the storage unit 36. These pieces of information are stored as IC / time identification information 50 shown in FIG. Thus, when the IC identification information of each of the entrance gate 12 and the exit gate 14 and each IC passage time are stored in the storage means 36, the control means 31 uses the distance database 40 to determine the distance difference between each IC, The time difference is calculated from the time.

  In this case, the IC identification information of the entrance gate 12 is “10” and the passage time is “10:15”, and the IC identification information of the exit gate 14 is “16” and the passage time is “12:00”. The distance difference between the ICs is “150 km” and the time difference is “1 hour 45 minutes”. Therefore, the average speed is calculated as “100 km / h”.

  By using the ETC in-vehicle device 30 in this way, the traveling speed of the vehicle 1 can be calculated without newly installing an operation record collecting device and a GPS device, so the traveling speed of the vehicle 1 can be managed easily and inexpensively. . In addition, this method is suitable for a method in which a transportation company manages the traveling speed of a truck for each driver. In that case, it is necessary to install the ETC in-vehicle device 30 in all the trucks and distribute an ID card that can identify themselves to all drivers, but the transportation company can manage the average speed of the truck for each driver. . When the driver finishes the delivery and returns to the shipping company, the average speed calculated together with the delivery slip is printed and submitted by the output means 37 of the ETC on-board unit 30. Immediate attention can be given to drivers who drive beyond. Further, the ETC on-vehicle device 30 may issue a warning announcement from the output means 37 when determining that the calculated average speed exceeds the legal speed.

Instead, the distance between adjacent gates in all gates may be stored in advance, and the distance between both gates of the first gate and the second gate may be calculated by the sum of the distances between adjacent gates. . In that case, if the first gate and the second gate are adjacent to each other, the distance between the adjacent gates is stored in advance, and is calculated immediately. However, if the first gate and the second gate are not adjacent to each other, one or a plurality of gates existing between the first gate and the second gate, Is calculated by adding up the distances.

  In the embodiment, the configuration in which the calculated average speed is output by the output unit 37 has been described as an example. However, the present invention is not limited to this, and the calculated average speed is external to the ETC on-vehicle device 30 (for example, the transportation company's It may be configured to transmit to a management server or the like. In that case, it is necessary to provide external communication means instead of the output means 37.
