  For example, in each of the above-described embodiments, the configuration using time, road ID, and position coordinates is exemplified as the route information. However, the configuration of the route information is not particularly limited as long as it is information indicating the history of the travel route of the vehicle. For example, a configuration using a position ID indicating a position instead of a road ID or position coordinates may be used.

  Further, in each of the above-described embodiments, the configuration in which the password is input by the user and transmitted when receiving the route information or the travel history information is exemplified (S23, S103). However, a configuration in which a password transmitting device such as the mobile phone terminal 30 or the second in-vehicle device 20 automatically transmits a registered password without being input by the user. In that case, a configuration using an ID of the device instead of the password may be used.

  Further, in S2 and S72 of the information acquisition process of each of the above embodiments, a comment may be input in addition to the nickname. In that case, when displaying the route information and the travel history information list 53, the comment may be displayed together.

For example, a method of identifying a passenger by photographing a passenger with an in-vehicle camera installed inside the vehicle and collating with information registered in advance in the first in-vehicle device 10, or mobile communication possessed by the passenger There may be a method of recognizing a device using short-range wireless communication or the like, and thereby identifying a passenger.

  Moreover, in each said Example, although the structure which identifies a passenger individual by a nickname was illustrated, the structure which identifies other than a passenger may be sufficient. For example, in Example 1, it can be considered that the identification information (device ID, etc.) of the mobile phone terminal 30 is registered instead of the nickname of the passenger in S2. Furthermore, the structure which the 1st vehicle-mounted apparatus 10 and the mobile telephone terminal 30 communicate using short distance wireless communication etc., and registers the identification information of the mobile telephone terminal 30 automatically may be sufficient. When registering the identification information of the mobile phone terminal 30, the registered mobile phone terminal 30 can be configured to receive only the route information related to the route on which the mobile phone terminal 30 traveled on the first vehicle. Good.

  Further, in the first embodiment, before the route information is transmitted from the first in-vehicle device 10 to the mobile phone terminal 30, a list of route information is displayed on the mobile phone terminal 30, and the one selected from the list is displayed. It is good also as a structure which transmits to the mobile telephone terminal 30. FIG.

Moreover, in the said Example 1, although the structure which transmits route information and a nickname to the mobile telephone terminal 30 was illustrated, the structure which transmits only route information may be sufficient.
Moreover, in the said Example 2, although the structure which transmits path | route information to the server apparatus 40 when the predetermined time came was illustrated, when the process of S74 was performed a predetermined number of times, it transfers to S76 and path information It is good also as a structure which transmits.
