-First embodiment-
FIG. 1 shows the configuration of the navigation device according to the first embodiment of the present invention. The navigation device 1A of FIG. 1 is provided with a seat sensor 113 in the driver's seat, and can detect the movement of the center of gravity of the user sitting in the driver's seat. The navigation device 1A includes a control circuit 11, a ROM 12, a RAM 13, a current location detection device 14, an image memory 15, a display monitor 16, an input device 17, a speaker 18, a touch panel 19, a disk drive 111, and a sheet sensor 113. The disk drive 111 is loaded with a DVD-ROM 112.

  The control circuit 11 includes a microprocessor and its peripheral circuits, and performs various controls by executing a control program stored in the ROM 12 using the RAM 13 as a work area. When the control circuit 11 performs a predetermined route search process based on the map data stored in the DVD-ROM 112, the processing result is displayed on the display monitor 16 as a recommended route.

  The current position detection device 14 is a device that detects the current position of the vehicle. For example, a vibration gyro 14a that detects the traveling direction of the vehicle, a vehicle speed sensor 14b that detects the vehicle speed, and a GPS signal from a GPS (Global Positioning System) satellite. It consists of a GPS sensor 14c and the like. 1 A of navigation apparatuses determine the display range of a map, a route search start point, etc. based on the present location of the vehicle detected by this present location detection apparatus 14, and display the present location on a map.

  The image memory 15 stores image data to be displayed on the display monitor 16. This image data includes road map drawing data and various graphic data, which are appropriately generated based on map data stored in the DVD-ROM 112 read by the disk drive 111. The navigation device 1 can perform map display and the like by using the image data generated in this way.

  The disk drive 111 reads map data for displaying a map on the display monitor 16 from the loaded DVD-ROM 112. The map data includes map display data, route search data, and the like. The map display data and the route search data include road link information and node information stored in the map data. The map display data has map data of a plurality of scales from wide areas to details, and the scale of the display map can be changed according to a user request. The map data may be read from a recording medium other than the DVD-ROM 112, such as a CD-ROM or a hard disk.

  The display monitor 16 provides the user with various information such as a road map near the vehicle position as a screen display based on various information such as map data. The input device 17 has operation keys for the user to set various commands, and is realized by an operation panel, a remote controller, or the like. The user selects and sets the destination by manually operating the input device 17 in accordance with the instructions on the display screen of the display monitor 16. The speaker 18 outputs sound for guiding the operation to the user and guiding the route.

  When the destination is set by the user, the navigation apparatus 1 performs a route calculation from the current location detected by the GPS sensor 14c to the destination based on a predetermined algorithm. Hereinafter, this route calculation is called a search calculation. The route thus obtained (hereinafter referred to as a recommended route) is displayed on the screen separately from other roads by changing the display form, for example, the display color. Thereby, the user can recognize the recommended route on the map on the screen. In addition, the navigation device 1 displays the recommended route on the road map displayed on the display monitor 16 so that the vehicle can travel according to the recommended route, and instructs the user on the direction of travel using a screen, voice, etc. To guide the route.

  The touch panel 19 is a transparent panel provided on the monitor screen of the display monitor 16, and the display screen displayed on the display monitor 16 is displayed through the touch panel 19. When the display screen of the display monitor 16 is pressed, a position signal corresponding to the pressed position is output from the touch panel 19, and the pressed position is calculated in the touch panel control unit 110. The touch panel 19 has an input function like the input device 17. When a map screen displayed on the display monitor 16 or a menu of various functions, buttons, icons, or the like is pressed with a finger, the touch panel 18 is pressed and a position signal is output to the touch panel control unit 110. The touch panel control unit 110 calculates a pressed position and outputs the calculated pressed position to the control circuit 11. Then, the control circuit 11 sets a destination based on the pressed position, and executes processing defined in various function menus, buttons, and icons.

  The seat sensor 113 is composed of a plurality of pressure sensors, and detects the movement of the center of gravity of the user sitting in the driver's seat. Details of the sheet sensor 113 will be described with reference to FIG. FIG. 2A is a view showing the seat 20 of the driver's seat. The seat 20 includes a seat head portion 21, a seat back portion 22, and a seat seat surface portion 23. The seat seat surface portion 23 is provided with three pressure sensitive sensors 24 a to 24 c constituting the seat sensor 113. As shown in FIG. 2B, two pressure-sensitive sensors 24a and 24b are provided in parallel on the vehicle traveling direction side of the seat seat surface portion 23, and one is provided on the side opposite to the vehicle traveling direction of the seat seat surface portion 23. A pressure sensitive sensor 24c is provided. These pressure sensors 24a to 24c receive pressure based on the weight of the user sitting in the driver's seat. The pressure detected by the pressure sensors 24a to 24c is constantly monitored by the control circuit 11, and the center of gravity of the user is detected by the pressure change detected by the pressure sensors 24a to 24c. For example, when the pressure detected by the pressure sensors 24a and 24b increases and the pressure detected by the pressure sensor 24c decreases, the movement of the center of gravity in the vehicle traveling direction is detected.

  Next, a push button determination process for determining whether the button displayed on the display screen has been pressed by the driver seat user or the passenger seat user will be described with reference to FIGS.

  FIG. 3 is a diagram for explaining a display screen displayed on the display monitor 16. A map 30 is displayed on the display screen. A self-vehicle position mark 31 is superimposed on the map 30. On the right side of the map 30, a wide area button 32a for switching the map 30 to the wide area map, a detailed button 32b for switching the map 30 to the detailed map, and a menu button 32c for opening the main menu are displayed. Here, since the vehicle is running, it is assumed that the user at the driver's seat is prohibited from opening the menu screen.

  As shown in FIG. 3, the pressure detected by the sheet sensor 113 when the menu button 32c is pressed is shown in FIG. 4A shows the pressure detected by the pressure sensor 24a, FIG. 4B shows the pressure detected by the pressure sensor 24b, and FIG. 4C shows the pressure detected by the pressure sensor 24c. . The time t1 shown in FIGS. 4A to 4C is the time when the menu button 32c is pressed. When the menu button 32c is pressed (time t1), the pressure detected by the pressure-sensitive sensors 24a and 24b provided on the seat traveling surface side of the seat seat surface portion 23 is increased, and the vehicle traveling direction of the seat seat surface portion 23 is increased. The pressure detected by the pressure sensitive sensor 24c provided on the opposite side is small. From this, it can be seen that when the menu button 32c is pressed, the center of gravity of the user at the driver's seat has moved in the vehicle traveling direction. Therefore, when such a pressure change is detected, it can be determined that the user at the driver's seat has pressed the menu button 32c. In this case, since the operation of opening the menu screen of the user at the driver's seat while the vehicle is traveling is prohibited, the menu screen is not displayed even when the menu button 32c is pressed.

  On the other hand, when the pressure detected by the seat sensor 113 is as shown in FIG. 5, it can be determined that the user at the passenger seat has pressed the menu button 32 c, and the menu screen is displayed on the display monitor 16. 5A shows the pressure detected by the pressure sensor 24a, FIG. 5B shows the pressure detected by the pressure sensor 24b, and FIG. 5C shows the pressure detected by the pressure sensor 24c. Pressure. The time t1 shown in FIGS. 5A to 5C is the time when the menu button 32c is pressed as in FIG. When the menu button 32c is pressed, the pressure detected by the pressure sensitive sensors 24a to 24c is substantially constant and has not changed. From this, it can be seen that when the menu button 32c is pressed, the center of gravity of the user at the driver's seat has not moved. Therefore, it can be determined that the menu button 32c has not been operated by the driver seat user, that is, has been operated by the passenger seat user.

  When it is determined that the user at the passenger seat has operated, the menu screen 33 is displayed on the display monitor 16 when the menu button 32c is pressed, as shown in FIG. Here, the menu screen 33 includes a search button 34a for searching for a destination facility, a setting button 34b for performing various settings, a search button 34c for searching for a recommended route, and a traffic information button 34d for displaying traffic information. Is displayed.

  Next, referring to the flowchart of FIG. 7 for button invalidation processing in which the processing defined for the button is not executed even if the user of the driver seat presses the button for which the operation of the driver seat user is prohibited. I will explain. The processing of FIG. 7 is performed by executing a program that starts when a button is displayed on the display screen in the control circuit 11. For convenience of explanation, the pressure sensor 24a is referred to as a pressure sensor A, the pressure sensor 24b is referred to as a pressure sensor B, and the pressure sensor 24c is referred to as a pressure sensor C.

  In step S <b> 701, the pressure is detected by the pressure sensitive sensors A to C constituting the sheet sensor 113. In step S702, it is determined whether the detected pressure is substantially constant for a predetermined time or more. If almost constant, step S702 is affirmed and the process proceeds to step S703. If it is not substantially constant, a negative determination is made in step S702, and the process returns to step S701. In step S703, the average value of the pressures detected by the pressure sensor A, the pressure sensor B, and the pressure sensor C for a predetermined time is calculated as the reference pressure of each of the pressure sensors A to C.

  In step S704, pressure is detected by the pressure sensitive sensors A to C. In step S705, the pressure of the pressure sensor A is greater than the reference pressure by a predetermined value, the pressure of the pressure sensor B is greater than the reference pressure by a predetermined value, and the pressure of the pressure sensor C is greater than the reference pressure by a predetermined value. It is determined whether it has become smaller. If a positive determination is made in step S705, the process proceeds to step S706, and if a negative determination is made in step S705, the process proceeds to step S708.

  In step S706, the button 32c for which the operation of the driver's seat user is restricted is disabled. At this time, even if the button 32c is pressed, the processing defined for the button 32c is not executed. In step S707, based on the signal output from the touch panel 19, it is determined whether the touch panel has been pressed for a predetermined time or more. If it is not pressed, an affirmative determination is made in step S707 and the process returns to step S702. If it is pressed, a negative determination is made in step S707, and the process returns to step S704.

  In step S708, a button for which the operation of the driver's seat user is restricted is enabled. At this time, when the button 32c is pressed, the process defined for the button 32c is executed.

The navigation device 1A according to the first embodiment described above has the following operational effects.
(1) It is possible to specify which of the user at the driver's seat and the user at the passenger's seat has pressed the touch panel 19 of the navigation device 1A. Therefore, it is not necessary to hide the button 32c that restricts the operation of the driver's seat user.

(2) The seat sensor 113 provided on the seat 20 of the driver's seat specifies which of the user at the driver's seat and the user at the passenger's seat has pressed the touch panel 19, so that the user sitting on the seat Based on the movement of the center of gravity, the user who pressed the touch panel 19 can be reliably identified.

(3) The reference pressure of the pressure sensitive sensors 24a to 24c is calculated, the detected pressure is compared with the reference pressure, and the user who pressed the touch panel 19 is specified. Therefore, the user who operated the touch panel 19 can be specified even if the user is sitting, for example, leaning forward or sitting by the seat back surface portion 22.

The navigation device 1A of the above embodiment can be modified as follows.
(1) Although the seat sensor 20 is provided in the driver's seat, it may be provided in the passenger seat. By providing it in the passenger seat, it can be more reliably determined whether the operation is a user operation on the driver seat or a user operation on the passenger seat.

(2) As shown in FIG. 8A, pressure-sensitive sensors 41 a and 41 b may be provided on the seat back surface portion 22 instead of the seat seat surface portion 23. When the driver's seat user operates the navigation device, the center of gravity of the driver's seat user moves in the vehicle traveling direction. For this reason, the pressure detected by the pressure sensitive sensors 41a and 41b provided on the seat back surface portion 23 is reduced. Therefore, by monitoring the pressure detected by the pressure-sensitive sensors 41a and 41b provided on the seat back surface portion 22, it is specified whether the operation of the navigation device 1A is a driver seat user or a passenger seat user. Can do. Moreover, as shown in FIG.8 (b), you may provide the pressure sensitive sensors 24a-24c, 41a, 41b in both the back surface part 22 and the seat seat surface part 23, and by this, it is more reliable. It can be determined whether the operation is a driver seat user operation or a passenger seat user operation.

(3) When the driving positions of a plurality of users are stored in a memory such as the RAM 13 by the automatic driving position system, an algorithm for determining the user who operated the navigation device 1A is also stored at the same time. The user who operates the navigation device 1 may be determined. For example, when Mr. A operates the navigation apparatus 1, let us consider a case where Mr. B does not separate his back from the seat back surface portion 22 and Mr. B does not separate his back from the seat back surface portion 22. When the driving position operated by the auto driving position system is the driving position set by Mr. A, when the pressure-sensitive sensors 41a and 41b provided on the seat back surface portion 22 no longer detect pressure, the user at the driver's seat It is determined that the navigation device 1A has been operated. On the other hand, when the driving position is Mr. B's driving position, the user at the driver's seat operates the navigation device 1A when the pressure of the pressure sensitive sensors 41a and 41b provided on the seat back surface portion 22 is detected to be lower than the reference pressure. Judge that The driver position user can be identified by the driving position operated by the auto driving position system, so that an algorithm can be provided according to the personality of the driver seat user, and the user who pressed the touch panel 19 more reliably can be determined. Can be identified.

(4) It is also possible to determine whether the driver's seat user has operated the navigation device 1A or the passenger's seat user has operated the navigation device 1A by performing image processing on the image captured by the image sensor or the infrared sensor. Good. In this case, the driver's seat user and the passenger's seat user are photographed, and the driver's seat user operates the navigation device 1A depending on which user has operated the navigation device 1A. It is determined whether the navigation device 1A has been operated.

Two images are displayed on the display monitor 16, and one image can be seen from the driver's seat side and another image can be seen from the passenger seat side by the optical system separation element arranged on the front surface of the liquid crystal panel of the display monitor 16. The display monitor control unit 114 generates a display image so that one image can be seen from the driver seat side and another image can be seen from the passenger seat side. For example, a video signal of the display monitor 16 is generated so that a map near the vehicle position is presented in the driver's seat and a digital terrestrial broadcast video is presented in the passenger seat.

  The speaker 18 outputs audio information of terrestrial digital broadcast received by the terrestrial digital broadcast receiver 115.

  With reference to FIGS. 4, 5, 10, and 11, a description will be given of the push button determination processing as to which of the buttons defined on the driver's seat screen and the passenger's seat screen is to be executed.

  FIG. 10 is a diagram illustrating a driver seat screen. As shown in FIG. 10A, a display screen similar to FIG. 3 is displayed on the driver's seat screen of the display monitor 16.

On the other hand, if the pressures detected by the pressure sensitive sensors 24a to 24c when the menu button 32c is pressed are as shown in FIGS. 5A to 5C, it is determined that the user at the passenger seat has operated. Even if the menu button 32c is pressed, the menu screen 33 is not displayed.

  FIG. 11 is a diagram for explaining the passenger seat screen. On the passenger seat screen, as shown in FIG. 11A, an image of digital terrestrial broadcasting is displayed. A menu button 61 for opening a channel switching screen is displayed on the right side of the video, superimposed on the digital terrestrial broadcast video. The display position of the menu button 61 is assumed to be the same as the display position of the menu button 32c displayed on the display screen that can be seen from the driver's seat side.

  As shown in FIG. 11 (a), when the user in the passenger seat presses the menu button 51, a channel switching screen 62 is displayed as shown in FIG. 11 (b). Here, on the channel switching screen 62, channel buttons 63a to 63h for switching the channel of the terrestrial digital broadcast being viewed are displayed.

  That is, when the pressure detected by the pressure-sensitive sensors 24a to 24c when the menu button 61 is pressed (time t1) is as shown in FIGS. The channel switching screen 62 shown in FIG. 11B is displayed. On the other hand, when the pressure detected by the pressure sensitive sensors 24a to 24c when the menu button 61 is pressed (time t1) is as shown in FIGS. Even if the menu button 61 is pressed, the channel switching screen 62 is not displayed.

  As described above, even if the display position of the menu button 32c in the driver's seat screen and the menu button 61 in the passenger's seat screen are the same, the driver's seat is monitored by monitoring the pressure detected by the pressure sensitive sensors 24a to 24c. It is possible to determine whether the user has pressed the menu button 32c or the user at the passenger seat has pressed the menu button 61.

  Next, a processing button determination process for determining which button to execute the process defined for the button displayed on the driver's seat screen or the button displayed on the passenger seat screen is shown in the flowchart of FIG. The description will be given with reference. The process of FIG. 12 is performed by executing a program that starts when a button is displayed on the display screen in the control circuit 11. Here, the same steps as those in the button invalidation process of FIG. 7 in the first embodiment are denoted by the same reference numerals, and different portions from the button invalidation process in the first embodiment will be mainly described.

  In step S705, the pressure of the pressure sensor A is greater than the reference pressure by a predetermined value, the pressure of the pressure sensor B is greater than the reference pressure by a predetermined value, and the pressure of the pressure sensor C is greater than the reference pressure by a predetermined value. It is determined whether it has become smaller. If a positive determination is made in step S705, the process proceeds to step S1201. If a negative determination is made in step S705, the process proceeds to step S1202.

  In step S1201, the button displayed on the driver's seat screen is enabled, and the button displayed on the passenger seat screen is disabled. Then, the process proceeds to step S707. In step S1202, the button displayed on the passenger seat screen is enabled, and the button displayed on the driver seat screen is disabled. Then, the process proceeds to step S707.
