  The display 28 is composed of, for example, a liquid crystal display or an organic EL (Electro-Luminescence) display, and has a function of displaying map information, own vehicle position, distribution information, etc. on the screen and showing it to the user. Here, a touch panel display may be employed as the display 28.

  The operation unit 30 is a part where the user performs an operation to change the function and display of the vehicle position display device 11. As a specific mode of the operation unit 30, a switch arranged at a site different from the display 28 is employed. The operation unit 30 in this embodiment is arranged on the steering or its peripheral part for the convenience of operation. As a specific example of the operation unit 30, a joystick, a cross key, and the like, which will be described later, are employed to simplify the operation. In this embodiment, even when a touch panel is adopted as the display 28, the operation unit 30 is provided separately.

  The speed sensor 32 has a function of measuring the speed at which the vehicle 10 moves. The speed sensor 32 measures the speed from the rotational speed of the wheel, for example.

  Referring to FIG. 1B, in the present embodiment, the above-described display 28 and operation unit 30 are arranged separately as separate elements. Specifically, the display 28 is arranged at a position where the user who is driving in the vehicle can visually recognize the line of sight without much diverting. On the other hand, the operation unit 30 is provided on the steering 40 itself so that a user who is operating the steering 40 can easily operate the operation unit 30. Here, the operation unit 30 is not necessarily provided in the steering 40, and may be disposed in the vicinity thereof as a separate element from the steering 40.

  With reference to FIG. 2, the specific aspect of the above-mentioned operation part 30 is demonstrated. 2A shows a steering equipped with an operation unit, FIG. 2B shows a joystick as an operation unit, and FIG. 2C shows a cross key as an operation unit. .

  With reference to FIG. 2 (A), in this embodiment, an operation unit 30 for operating distribution information displayed on the display is arranged on the steering 40. Specifically, the operation unit 30 is disposed in the vicinity of the connection portion between the wheel rim 40A and the spoke 40B. Accordingly, the distribution information can be operated by the user pressing the operation unit 30 with a thumb or the like while holding the steering wheel 40. Therefore, since the user does not release his / her hand from the steering wheel 40 for operation and it is not necessary to turn his line of sight toward the operation unit, there is less risk of a traffic accident even in a situation where the user operates during driving.

  Referring to FIG. 2B, a joystick 42 can be employed as the operation unit described above. The joystick 42 is a cylindrical switch provided on the spoke 40 </ b> B of the steering 40. A predetermined electric signal is generated by tilting the joystick 42 in any one of D1 (first direction), D2 (first direction), D3 (third direction), and D4 (fourth direction). Here, D1 and D2 are directions opposite to each other, and D3 and D4 are opposite to each other so as to be orthogonal to these directions.

  The electrical signal generated when the user tilts the joystick 42 may indicate only the tilted direction (D1, D2, D3, or D4). Thereby, the temporal and distance distribution range of the distribution information described later is changed.

  Further, in addition to this, the generated electric signal may indicate the degree of inclination. Thereby, the degree to which the distribution range is changed may be changed according to the degree to which the joystick 42 is tilted. For example, by increasing the angle at which the joystick 42 is tilted, distribution information in a wider area can be displayed on the display.

  Referring to FIG. 2C, a cross key 44 may be employed as the operation unit. The cross key 44 is an operation button having a cross shape in plan view, and by pressing down one of the ends extending in four directions, an electrical signal corresponding to the direction is generated. Here, as in the case of the joystick, the electrical signal generated by pressing the cross key 44 may reflect the pressing direction and the pressing level.

  With reference to FIG. 3, the vehicle position display device of this embodiment is provided in a vehicle 10 typified by an automobile.

  The vehicle 10 can know the absolute position (own vehicle position) by receiving data from the artificial satellite 12 for GPS (Global Positioning System). Further, by transmitting and receiving data to and from the data communication network 14, distribution information related to the map information is distributed to the vehicle 10. The data communication network 14 is, for example, an infrastructure (VICS (registered trademark): Vehicle Information and Communication System) implemented by a public organization, a mobile phone communication network, or the like. By displaying the distribution information obtained from the data communication network 14 on the display device, the user can know the desired information.

  As information transmitted from the data communication network 14 to the vehicle 10, information related to a map or the like is employed. Specifically, store information such as restaurants and gas stations, event information, product advertisements, and traffic information (for example, the occurrence of traffic accidents) are transmitted to the vehicle 10. Furthermore, these pieces of information may be selected based on information (life log) such as the position, state, and preference of the user who drives the vehicle. The collection of the life log can be extracted from the operation of the vehicle position display device by the user.

  The communication between the vehicle 10 and the data communication network 14 may be in one direction in which data is transmitted only from the data communication network 14 to the vehicle 10, or data based on a request transmitted from the vehicle 10 to the data communication network 14. A bidirectional type in which data is transmitted from the communication network 14 to the vehicle 10 may be used. Furthermore, push-type communication in which a predetermined type of information is transmitted from the data communication network 14 to the vehicle 10 without a request from the vehicle 10 may be performed.

  With reference to FIG. 4, the matter which changes the range of delivery information by operating the above-mentioned operation part is demonstrated.

  On the display 28 shown in this figure, when the user drives the vehicle, a map of a predetermined scale is displayed superimposed on the own vehicle. In this embodiment, in addition to these, the distribution information related to the map information is also displayed on the display 28. Here, the distribution range in which the distribution information is distributed may be based on the current vehicle position or may be another part (for example, a set destination).

  As described above with reference to FIG. 2, the operation unit of this embodiment can be operated in four directions (D1, D2, D3, and D4), and each direction is related to the change of the information distribution range. doing.

Here, the distance range of the displayed distribution information can be changed by operating the operation unit in the D1 direction or the D2 direction opposite to the vertical direction on the paper. For example, by operating the operation unit in the direction D1, the range of distribution information to be displayed becomes a wide range. Conversely, by operating the operation unit in the D2 direction, the range of the distribution information to be displayed becomes a narrow range.

Furthermore, the time range of the distribution information to be displayed can be changed by operating the operation unit in the D3 direction or the D4 direction opposite to the left-right direction on the paper. For example, by operating the operation unit in the direction D3, the displayed distribution information becomes the past side . On the other hand, by operating the operation unit in the D4 direction, the displayed distribution information becomes the future side .

  Here, the degree of change may be increased by increasing the degree of operation in each direction described above. For example, a wider range of distribution information may be displayed on the display 28 by strongly pressing the operation unit in the D1 direction. In this way, the user can easily narrow down information.

  With reference to the flowchart of FIG. 5 and each of the above-described drawings, a method for changing the range of distribution information to be displayed by operating the operation unit will be described in detail.

  First, in step S10, the user operates the operation unit to change the range of distribution information. The operation here means tilting the joystick 42 in a predetermined direction in the case shown in FIG. 2B, and pressing any one end of the cross key 44 in the case shown in FIG. 2C. It is.

  When the operation of the operation unit described above is in the D1 direction, it is determined that the user desires to expand the range of distribution information displayed (YES in step S11).

  When the operation of the operation unit by the user is larger than the first operation amount specified in advance (YES in step S12) and smaller than the second operation amount specified larger than the first operation amount (step For example, the distribution range is expanded to 5 km. This is because it is determined that the user wants to expand the distribution information. Here, each operation amount is an inclination angle in the case of the joystick 42 shown in FIG. 2B, and a pressing force in the case of the cross key 44 shown in FIG.

  On the other hand, if the operation amount of the operation unit is smaller than the first operation amount (NO in step S12), the range of the displayed distribution information is not changed (step S18).

  Further, if the operation amount of the operation unit is larger than the second operation amount (NO in step S13) and smaller than the third operation amount defined to be larger than the second operation amount (YES in step S15), further. It is determined that the user wants to expand the distance range, and the distribution range is further expanded to 10 km.

  Furthermore, if the operation amount of the operation unit is larger than the third operation amount (NO in step S15), it is determined that further range expansion is requested, and the distribution range is expanded to 20 km.

  Here, in the above description, the distribution range of the distribution information is expanded in three stages according to the magnitude of the operation amount in the direction D1, but this stage may be two stages or four or more stages.

  The distribution range changing method described above is the same in other directions.

  That is, when the operation of the operation unit by the user is in the D2 direction (YES in step S21), the distribution range is reduced by the same method as described above. Specifically, when the operation amount is larger than the first operation amount (YES in step S22) and smaller than the second operation amount (YES in step S23), the distribution range is reduced to 1 km (step S24). Furthermore, when the operation amount is larger than the second operation amount (NO in step S23) and smaller than the third operation amount (YES in step S25), the distribution range is further reduced to 0.5 km (step S26). If the operation amount is larger than the third operation amount (NO in step S25), the distribution range is further reduced to 0.1 km (step S27).

  If the operation performed is in the direction D3 (YES in step S31), the distribution range is changed in the past. Specifically, when the operation amount is larger than the first operation amount (YES in step S32) and smaller than the second operation amount (YES in step S33), the distribution range is changed yesterday (step S34). Furthermore, when the operation amount is larger than the second operation amount (NO in step S33) and smaller than the third operation amount (YES in step S35), the distribution range is changed to last week (step S36). When the operation amount is larger than the third operation amount (NO in step S35), the distribution range is changed to last month (step S37).

  On the other hand, if the operation performed is in the D4 direction (YES in step S41), the distribution range is changed to the future. Specifically, when the operation amount is larger than the first operation amount (YES in step S42) and smaller than the second operation amount (YES in step S43), the distribution range is changed tomorrow (step S44). Furthermore, when the operation amount is larger than the second operation amount (NO in step S43) and smaller than the third operation amount (YES in step S45), the delivery range is changed to next week (step S46). When the operation amount is larger than the third operation amount (NO in step S45), the distribution range is changed to next month (step S47).

  As described above, the distribution range of the distribution range desired by the user can be immediately displayed on the display by subdividing and changing the distribution range according to the operation amount.
