The program is stored in the memory 30B, and is executed by the CPU 30A when a processing start instruction signal is received from a vehicle control device (not shown), for example, when an engine switch of a vehicle on which the vehicle-mounted device 12 is mounted is turned on. Is done.

  Next, in step S10, for example, it is determined whether or not a processing end instruction signal is input from a vehicle control device (not shown) by turning off the engine switch of the vehicle. If the determination is negative, the process proceeds to step S11. On the other hand, if the determination is affirmative, the process of the distribution control program ends.

  In step S11, the distance (or estimated arrival time) between the approaching roadside device 14 and the host vehicle is calculated based on the position information of the host vehicle obtained from the car navigation system.

  In step S12, it is determined whether or not the calculation result in step S10 matches a predetermined condition (for example, within 500 m or within 1 minute). If the determination is affirmative, the process proceeds to step S14, and a negative determination is made. When it becomes, it transfers to step S10.

  In step S14, the storage unit 30C is searched, the content corresponding to the approaching roadside device 14 is read (cached) into the memory 30B, and preparations for transmission are made.

  In step S16, the wireless communication unit 38 waits for detection of entering the communication area with the roadside device 14 according to the wireless method.

  When the roadside device 14 becomes a communication area and can communicate wirelessly with the vehicle-mounted device 12, the roadside device 14 transmits the roadside device ID of the roadside device 14 and a transmission condition as necessary.

  In step S18, the roadside device ID and the transmission condition received from the roadside device 14 are received. This transmission condition is, for example, a content version, a generation date and time, and the like.

  In step S20, it is determined whether or not the roadside unit ID received in step S18 is that of the roadside unit 14 that is the transmission target of the content cached in step S14. If the determination is affirmative, the process proceeds to step S24. And when it becomes negative determination, it transfers to step S22.

  In step S22, since the content corresponding to the roadside unit ID received in step S18 is not cached, the storage unit 30C is searched and the content corresponding to the received roadside unit ID is read into the memory 30B (cache). .

  In step S24, content that matches the transmission condition received in step S18 is extracted as a transmission target from the cached content. If there is no condition, all cached contents are targeted for transmission.

  In step S26, when the content to be transmitted is prepared for transmission, the content is transmitted.

Further, the roadside device 14 evaluates the value of the uploaded content and transmits incentive information corresponding to the evaluation value to the vehicle-mounted device 12. When this content is advertising information, a price corresponding to the given incentive may be imposed on the advertiser.
If the roadside device 14 has content other than the uploaded content, the roadside device 14 transmits the content to the vehicle-mounted device 12.

  In step S28, reception of content other than the incentive information and the uploaded content is waited for a predetermined period, and then the process proceeds to step S10.

  The received incentive information and content are stored in the storage unit 30C and displayed on the display panel 36 as appropriate.

  This incentive proof can be generally guaranteed on the client side, on the server side, or on both sides. In the present embodiment, the vehicle-mounted device 12 side corresponds to the client side, and the roadside device 14 or the operator of the roadside device corresponds to the server side. When guaranteeing on the client side, the server side creates content indicating the incentive content and sends it to the client. The client stores it and delivers it when receiving money, goods or services. Electronic money can also be part of this. When guaranteeing on the server side, the contents of the incentive are recorded in the incentive management server using information for identifying the on-vehicle device 12 (ID of the on-vehicle device 12) as a key. When the user requests to provide money, goods, services, etc., the possession incentive is confirmed using the ID of the vehicle-mounted device 12 as a key, and management is performed. In the case of having both, it is a hybrid type and manages the voucher presented by the client side by matching with the information on the server. Such information may use an electronic signature, a time stamp, authentication, encryption, or the like as a security means for preventing forgery.

  The partner who gives the incentive is the vehicle-mounted device 12 that uploaded the information. In general, the vehicle-mounted device 12 and the communication device are identified by an ID. In order to prevent ID spoofing, security means such as authentication may be used.

  As described above, according to the present embodiment, since the content can be distributed to each roadside device 14 without connecting the roadside device 14 to the network 26, the infrastructure installation cost and the operation cost can be reduced. it can. In addition, by storing the content (distribution information) for the roadside device 14 provided along the planned traveling route of the vehicle in which the onboard device 12 is mounted in the onboard device 12, the distribution information is transmitted to the roadside device 14. It is possible to appropriately distribute, and it is not necessary to store useless distribution information in the vehicle-mounted device 12.
