Vehicle-mounted device, roadside device and control method

Abstract

An ITS vehicle-mounted device (17) sends / receives data in DSRC Town Car Life Navi multi-content form. As a vehicle enters the communication area of a roadside apparatus (11), the past drop-in place information is sent to the ITS vehicle-mounted device (17) so that the driver can receive beneficial advertisement information from the ITS vehicle-mounted device (17). Places where the power of the ITS vehicle-mounted device (17) is turned off may be registered as the past drop-in places contained in said past drop-in place information, and the places of an idling stop may also be registered in the past drop-in place information. In that case, the accuracy of the past drop-in place information is low. Highly accurate past drop-in place information can be produced, however. When the stop time is short at a place where the power of the ITS vehicle-mounted device (17) is turned off or when a place is on the road right before an intersection as indicated by comparison with map data, said place will not be registered in the past drop-in place information.

Description

technical field [0001] The present invention relates to an in-vehicle device, a roadside device, a control method, and a program for performing road-to-vehicle communication using wireless communication such as DSRC (Dedicated Short Range Communication). Background technique [0002] A road-to-vehicle communication system utilizing DSRC is disclosed in Reference Document 1 (Patent Document 1's figure 1 ). In this road-to-vehicle communication system, an on-board unit of a car entering the communication area of ​​the roadside machine receives advertisement information from the roadside machine through radio waves, and displays it on the display of the navigation unit (paragraph 0024 of Patent Document 1). In addition, in the vehicle-mounted device, destination setting, HP connection, and dialing are automatically performed based on the location information, URL, and telephone number contained in the advertisement information (Patent Document 1 Figure 4 S12, S14, S16).

AI Technical Summary

Problems solved by technology

The place where the idling stop is not the actual stop where the user gets out of the car to go shopping, etc. Therefore, it will be a disadvantage when the past stop information including the idling stop place is used as the basis for selecting useful advertisement information for each user

In addition, users will park their cars at their own homes, friends' homes, workplaces, etc., and it is not helpful to know their own homes, etc. as member information or as reference information for selecting transmission catalogs.

In addition, there is also the following problem: due to the limitation of the number of registrations of past stop information, the information of important parking places is overwritten by the information of unnecessary parking places, and the information of important past stop places decreases.

[0011] In patent documents 1 to 3, although the transmission of advertising information is mentioned, there is no suggestion for the information of past stops
