As a conventional advertisement system using a moving body such as a motor vehicle, there has been a system in which an advertisement is painted, pasted, or attached easily detachably on a motor vehicle, for example, a bus and payment for the advertisement is made for a predetermined period. Also used in recent years is a system, as disclosed in, for example, Japanese Patent Laid-open No. 2001-202455, which enables real-time advertisement display in a route bus by using roadside communications based on Dedicated Short Range Communication (DSRC) to exchange data of the advertisement between the bus and road side stations.
In the conventional system, however, an advertising provider often demands of an advertising agency (a party engaged in the advertisement activity) that the advertisement activity should cover predetermined traveling distance for displaying its advertisement. This demand has been a burden on the advertising agency due to the need for measuring and certifying the actual traveling distance for its advertisement. On the other hand, the advertising provider can not grasp based on only the traveling distance how much advertisement effect has been produced.
Further, for changing advertisements timely and easily, the conventional system needs new equipment of communications, namely the infrastructure, and telephone charges or the like in order to obtain information through, for example, a cellular phone. Moreover, even the use of the DSRC system has a problem such as the need for installing new dedicated base stations.
The present invention is made in view of the problems described above, and an object thereof is to provide an advertisement presenting and charging system that allows an advertising agency to be free from burden of measuring and certifying information for displaying an advertisement and changing advertisements without newly installing dedicated base station.

The display device 11 has a large number of LEDs arranged thereon and displays characters and graphics by the combination of their light spots.
In the advertisement presenting and charging system 1 of this embodiment, the motor vehicle 5 is allowed to pass without stopping when entering a toll road from a general road and when exiting from the toll road to a general road. At those times, the motor vehicle 5 receives advertisement data from the ETC fixed station 23 to display it and send advertisement displaying data to the fixed station 23.
FIG. 4 is a schematic view showing entrance data sent from the ETC fixed station 23 to the display device 11 when the motor vehicle 5 enters an entrance gate of an automatic toll collecting system for toll road from. FIG. 5 is a schematic view showing exit data sent from the motor from the display device 11 to the ETC fixed station 23 when the motor vehicle goes out of an exit gate of the automatic toll collecting system for toll road.
The entrance data 6 that the motor vehicle 5 obtains from the ETC fixed station 23 by DSRC when entering the toll road includes, as shown in FIG. 4, identifiers (here, for example 1:ETC, 2:ADVERTISEMENT and 9:END), ETC entrance data, and advertisement data. The advertisement data includes the number of advertisements 61 (here, for example 2) indicating how many advertisement data are included, advertisement IDs 62 (here, for example 0123 and 0144) for identification of the kinds of advertisements, advertising providers' names 63 (here, for example OOO . . . and XXX . . . ) showing the company names of advertising providers, the number of advertisement characters 64 (here, for example 10 and 9) used for a display process and a charging process, and advertisement contents 65 being the contents actually displayed, for example, “GREAT DEALS ON . . . ”, and “LET'S GO TO . . . ”.
On the other hand, the exit data 7 that the motor vehicle 5 sends to the ETC fixed station 23 by DSRC when going out of the toll road includes, as shown in FIG. 5, identifiers (here, for example 1:ETC, 2:ADVERTISEMENT, and 9:END), ETC exit data, and display data. The display data includes the number of advertisements 71 (here, for example 1) indicating how many kinds of advertisements have been presented, advertisement IDs 72 (here, for example 0123) for identification of the kinds of advertisements, the number of advertisement times 73 (here, for example 10) indicating how many times the advertisement contents 65 have been displayed, the advertisement times 74 (here, for example 10:30 and 10:45) indicating the time when the advertisement was displayed, and advertisement places 75 (here, for example, NEAR TOMEI 150 and 180) showing where the advertisement was displayed.
Next, the operation of the advertisement presenting and charging system 1 according to the present embodiment will be described.
The data obtaining operation before the motor vehicle 5 enters a toll road will be first described.
In order to use the advertisement presenting and charging system 1 and ETC system, an owner of the motor vehicle 5 makes a contract with the credit company 4 in advance so that a toll for a toll road is deducted based on data from the ETC fixed station 23 from his/her credit card.
When entering the toll road from a general road, the motor vehicle 5 is allowed to pass through an ETC entrance gate without stopping. Namely, as the motor vehicle 5 enters a predetermined area near the ETC entrance gate, wireless communication is started between the ETC fixed station side antenna 24 provided at the ETC entrance gate and the ETC antenna 22 of the motor vehicle 5. Through this communication, the ETC unit 21 and the display device 11 obtain the ETC entrance data including the entrance data 6 shown in FIG. 4 from the ETC fixed station 23.
The advertisement data included in the entrance data 6 obtained by the ETC unit 21 is sent to the display device 11 to display its contents, such as “GREAT DEALS ON . . . ” according to the advertising data
The display device 11 thus can obtain data necessary for the advertisement activity at the same time when communicating with the ETC fixed station 23 and use it.
Next, the advertising operation of the display device 11 will be described.
When the passenger, such as a driver, of the motor vehicle 5 starts the advertisement activity after entering the toll road, he/she operates the operation switch 12 to select a desired advertisement based on the advertising providers' names 63 and the advertisement contents 65 of the plural obtained advertisements and to input the activation of the display. The passenger can enjoy the advertisement activity because of such selectivity, by himself/herself, of the advertisement.
In response to the input operation of the activation, the display device 11 starts to display the selected advertisement contents 65, for example, “GREAT DEALS ON . . . ”, “LET'S GO TO . . . ”, and so on, by the light spots of many LEDs so that the display can be seen from behind the motor vehicle 5, as shown in FIG. 3. Thus, the advertisement is presented to passengers of motor vehicles running behind it.
When the advertisement display is started, the display device 11 obtains the advertisement time 74 based on time inputted from the timer 13 and the vehicle position information from the navigator 32. It further obtains the traveling distance data from the instrument C/U 33. The display device 11 also obtains the traveling distance based on the vehicle speed from the vehicle speed sensor 31 and map information from the navigator 32.
The advertisement thus displayed by the display device 11 has a high advertisement effect when the toll road is congested with motor vehicles since many motor vehicles follow the motor vehicle 5 having the display device 11 mounted thereon. The vehicle speed at the time of the advertisement display by the display device 11 is stored for use in certifying the high advertisement effect.
Especially when the traffic is heavy, the advertisement can give some diversion to passengers of the following motor vehicles and make them relaxed. On the advertising agency, too, the congestion leads to the longer display and higher effect of the advertisement which increases payment for its advertisement, consequently reducing a toll for the toll road and a driver's irritation.
Next, the data outputting operation when the motor vehicle 5 goes out of a toll road will be described.
When the motor vehicle 5, having thus presented the advertisement, goes out of the toll road to a general road, it passes through the ETC exit gate without stopping. At this time, it communicates with the ETC fixed station 23 so that a toll for the toll road can be charged by ETC. Namely, the exit data 7, constituted of the ETC exit data outputted from the ETC unit 21 and the display data outputted from the display device 11, is transmitted from the motor vehicle 5 to the ETC fixed station 23 via the ETC antenna 22 and the ETC fixed station side antenna 24 provided at the ETC exit gate.
The display data includes vehicle speed and the traveling distance when the advertisement was presented, which makes it possible to grasp individual condition during advertising even when the advertisement was displayed a plurality of times.
Such simultaneous communication for the advertisement activity with the communication for ETC toll charging for the toll road results in reduced equipment cost.
Next, the toll charging operation according to each condition will be described.
In the above-described manner, the ETC fixed station 23 can obtain the advertisement contents 65, the advertisement time, the traveling distance, the vehicle position, the vehicle speed when the advertisement was presented, and so on. Therefore, the charged amount can be set based on the obtained conditions involved with the actual advertisement effect. The payment is made with the ETC credit card, or by deducting from the toll for the toll road that is paid through the use of ETC. Besides, by the obtained conditions, the advertising provider can grasp whether the advertisement had a high effect due to the congestion or it did not have a high effect due to relatively high speed running on the toll road.
Next, advantages of the advertisement presenting and charging system 1 according to the embodiment will be described.
The advertisement presenting and charging system 1 of the embodiment can bring about the following advantages.
In the advertisement presenting and charging system 1, the display device 11 attached to a motor vehicle 5 displays an advertisement to outside the motor vehicle 5. The instrument C/U 33 and the navigator 32 are provided in the motor vehicle 5, and the display device 11 obtains information from the instrument C/U 33 and the navigator 32. The display device 11 has the timer 13 detecting time and the operation switch 12 for changeover between operation and non-operation of the display device 11. The display device 11 is connected to the ETC unit 21 and the ETC antenna 22. When communicating with the ETC fixed station 23, the display device 11 obtains the plural advertisement data so that an advertising agency is allowed to select the advertisement contents, and to charge for the advertisement according to the traveling section (places), traveling time, traveling distance for the advertisement actually presented by the display device 11. Therefore, on the advertising provider's side, amount of payment can be set according to the detailed contents of the advertisement so as to be more commensurate with the actual advertisement effect. On the other hand, on the advertising agency's side, irritation during traffic congestion is reduced because the amount of payment increases due to traffic congestion.
Further, an amount corresponding to the payment for the advertisement is deducted from a toll for a toll road, so that only a low toll is required for using the toll road. This accelerates use of toll roads.
The entrance data, including the number of advertisements 61, the advertisement IDs 62, the advertising providers' names 63, the number of advertisement characters 64, the advertisement contents 65, is sent from the ETC fixed station 23 to the display device 11 through the communication with the ETC system when a motor vehicle 5 enters a toll road. The exit data, including the number of advertisements. 71, the advertisement IDs 72, the number of advertisement times 73, the advertisement time 74, and the advertisement places 75, is sent from the display device 11 to the EYC fixed station 23 through the communication with the ETC system when the motor vehicle 5 goes out of the toll road. Therefore, owing to the use of the ETC system, this system 1 can reduce the number of communication times and cost necessary for changing the advertisement contents and charging and cost of equipment.
In the foregoing, the advertisement presenting and charging system 1 of the present invention is described based on the embodiments. However, the specific configuration is not limited to these embodiments, and any change, addition, and so on in design are embraced therein without departing from the spirit of the present invention according to the claims.
For example, as a display device 11, a wiper with LEDs, shown in FIG. 6, may be adopted. Specifically, the wiper 52 has a large number of LED groups 8, and the LED groups 8 are controlled by a display control device 9. When the wiper 52 is operated, light emission by the LED groups 8 generates afterglow 101 in conjunction with the movement of the wiper 52 to display characters 102. In this manner, conspicuous and eye-catching display is made possible.
In stead of the ETC, a different system may be used as the automatic toll collecting system for toll road.
Further, the exit data 7 may be constituted of the number of advertisements 71, the advertisement IDs 72, the number of advertisement times 73, the advertisement time 74, and the advertisement places 75.
