[0093] figure 1 It is a figure which shows the structure of the in-vehicle information system which concerns on one Embodiment of this invention. figure 1 The vehicle information system shown is installed and used in a vehicle, and is realized by connecting an in-vehicle device 1 and a portable terminal 2 to each other via a USB (Universal Serial Bus) cable 3 . The vehicle-mounted device 1 is fixed in a vehicle, for example, installed in a dashboard of the vehicle or the like. The portable terminal 2 is a portable information terminal that can be held by a user, and is, for example, a mobile phone, a smartphone, or the like.
[0094] The vehicle-mounted device 1 is provided with a display unit 11 and operation keys (operation switches) 12a, 12b, 12c, 12d, and 12e. The display unit 11 is a display monitor capable of displaying various images, and is composed of, for example, a liquid crystal display. The operation keys 12 a to 12 e are operation switches for detecting user i...

[0174] In the first embodiment described above, an example of an in-vehicle information system is described in which allocation processing is performed in the portable terminal 2, and key signals are converted into operation commands based on the allocation result. On the other hand, in the second embodiment described below, an example of an in-vehicle information system that performs distribution processing in the vehicle-mounted device 1 and converts key signals into operation commands based on the distribution results will be described.
[0175] In addition, the structure of the in-vehicle information system of this embodiment is the same as figure 1 Same as shown. In addition, in the in-vehicle information system of this embodiment, the structures of the in-vehicle device 1 and the portable terminal 2 are the same as figure 2 Same as shown.
[0176] Figure 15 It is a diagram showing the flow of information between the vehicle-mounted device 1 and the mobile terminal 2...

[0212] Next, a third embodiment of the present invention will be described. In this embodiment, a processing method when the user selects an application program executed on the portable terminal 2 by operating the in-vehicle device 1 will be described. In addition, the structure of the in-vehicle information system of this embodiment, the structure of the in-vehicle device 1, and the structure of the portable terminal 2 are similar to figure 1 , 2 Respectively represent the same. Therefore, descriptions of these figures are omitted below.
[0213] In the present embodiment, the mobile terminal 2 executes an application selected by the user among a plurality of applications including the navigation application as described above. At this time, the user selects a desired application program by operating the operation unit 22 on the menu screen displayed on the display unit 21 of the mobile terminal 2 , thereby selecting an application program to be executed by the mobile term...
