A map database holding map data to be displayed, 16 is a RAM for storing programs and data for the control microcomputer 12 to perform processing, 17 is a voice output means for outputting by voice, and 18 is a control microcomputer 12. 19 is a display device for displaying a screen such as a navigation screen by controlling the Shift gear is in the neutral detection means for detecting that a neutral position.

  The control microcomputer 12 performs navigation processing in a single-vehicle mode that is a processing mode suitable for navigation in a single vehicle and a four-wheel mode that is a processing mode suitable for navigation in a four-wheeled vehicle. At that time, based on a predetermined signal related to the use target of the apparatus, a mode setting process is performed for setting whether or not to process in the single vehicle mode.

  When the navigation device is mounted on a single vehicle, a neutral ramp line for detecting that the transmission gear is in the neutral position is connected to the navigation device. The other end of the neutral ramp line is connected to a feed line to the neutral lamp. The neutral detection means 19 can detect that the transmission gear of the single vehicle is in the neutral position, that is, neutral, based on the signal from the neutral ramp line.

  FIG. 2 is a flowchart showing the mode setting process by the control microcomputer 12. In the initial state when the apparatus is turned on, the single vehicle mode is off. When the single vehicle mode is off, processing is performed in the four-wheel mode.

  When the mode setting process is started in response to power-on of the apparatus, it is determined in step 21 whether or not neutral is detected by the neutral detection means 19. If it is determined that neutral is detected, the single vehicle mode is turned on in step 22 and the process is terminated. In this case, the control microcomputer 12 subsequently performs processing in the single vehicle mode. If it is determined that neutral has not been detected, the process ends. In this case, the control microcomputer 12 subsequently performs processing in the four-wheel mode. Note that the mode setting process of FIG. 2 may be repeated at regular intervals on condition that the single vehicle mode is off.

  FIG. 3 is a flowchart showing a processing procedure in the case of performing various processes having different processing contents in the single vehicle mode and in the four-wheel mode. When the process is started, first, at step 31, it is determined whether or not the single vehicle mode is on. If it is determined that the single vehicle mode is on, processing in the single vehicle mode is performed in step 32, and the processing is terminated. On the other hand, if it is determined that the single vehicle mode is OFF, the process in the four-wheel mode is performed in step 33, and the process ends.

  FIG. 4 shows a display example on the navigation screen in the single vehicle mode. In the figure, reference numeral 41 denotes an area in which a distance to a preset destination is displayed in characters, 42 is a bar graphic showing the point of arrival in the journey from the departure point to the destination, and 42a is a bar graphic 42. , Part showing the ratio of the part that has already traveled with respect to the total stroke, 42b is a part showing the ratio of the part that will travel from now on, 43 is an area for displaying the distance to the next gas station on the route to the destination by characters, 44 is a region for displaying the distance to the next branch point on the route to the destination by characters, 45 is a region for indicating the direction to bend at the next branch point, and 46 is a direction to be bent at the next branch point.

  When the single vehicle mode is on, the control microcomputer 12 performs navigation processing in the single vehicle mode by turn-by-turn by displaying the arrow 46 and the like as shown in FIG. 4 in step 32 according to the flowchart of FIG. . If the single vehicle mode is off, in step 33, a map figure is displayed, and an icon or the like indicating the current position or traveling direction is displayed thereon, thereby performing navigation processing in the four-wheel mode.

  FIG. 4B shows the state of the navigation screen when the next branch point is closer than when the display of FIG. 4A is performed. FIG. 4C shows the state of the navigation screen when the vehicle approaches further and reaches 100 [m] before the next branch point. At this time, as shown in the figure, the control microcomputer 12 changes the display color of the character 46 indicating the distance to the next branch point, the character indicating the direction of turning at the next branch point, or the arrow graphic 46, and the size. The driver is alerted by changing or flashing the display. Thereby, the driver | operator of a single vehicle can recognize the direction which should approach at a branch point, and should turn at a branch point easily.

  In addition, this invention is not limited to the above-mentioned embodiment, It can deform | transform and implement suitably. For example, in the above description, the mode setting as to whether or not to operate in the single vehicle mode is performed by a program. Instead, a circuit for holding the first neutral detection output from the neutral detection means 19 is provided. By setting the value held by this as the mode setting value, the mode setting may be performed in hardware.

  In the above description, the detection result of the neutral detection means 19 is referred to for mode setting. Instead, a means for detecting whether or not the stand of the single vehicle is stored is provided, and this detection output is provided. The mode setting may be performed based on the above. In other words, storing the stand of the single vehicle is a condition for allowing the start of the single vehicle, and for that purpose, the single vehicle is often provided with means for detecting whether or not the stand is stored. By introducing the signal from the detection means to the navigation device, the navigation device can set the mode.

  As an alternative to the neutral detection means 19, other means for detecting reverse operation and parking brake operation in a four-wheeled vehicle can be used. In other words, when the navigation device is mounted on a four-wheeled vehicle, a reverse cord or parking brake cord is connected to the navigation device, and a reverse operation or parking brake operation is detected. Use this to set the mode. For example, when a reverse or parking brake operation is detected, the four-wheeled vehicle mode can be set, and when it is not detected, the single-vehicle mode can be set.

  In place of the neutral detection means 19, further means for detecting the inclination of the display screen of the navigation device, means for detecting a predetermined portion of the mounting bracket of the device, means for detecting a signal on a signal line specific to a single or four-wheeled vehicle Etc. can also be used.

  As a means for detecting the tilt angle, for example, one using an angle sensor can be used. In this case, for example, if the angle of the display panel is 70 degrees or more, the navigation device is regarded as being attached to the four-wheeled vehicle, and the operation mode is set to the four-wheeled mode. It can be set to the single vehicle mode by assuming that it is installed.

  As a means for detecting a predetermined portion of the mounting bracket, paying attention to the fact that the shape of the mounting bracket differs depending on whether it is mounted on a single vehicle or a four-wheeled vehicle, for example, a portion specific to the mounting bracket for a single vehicle is detected. Applicable. When this portion is detected, the navigation device can be regarded as being attached to a single vehicle and set the operation mode to the single vehicle mode.

  As a means for detecting a signal on a signal line specific to a single vehicle or a four-wheeled vehicle, in addition to detecting the reverse code or parking brake code described above for a four-wheeled vehicle, a neutral code signal for a single vehicle, for example, a vehicle speed pulse is detected. Applicable means. The vehicle speed pulse is usually supplied to the navigation device when mounted on a four-wheeled vehicle. Therefore, the navigation device can set the mode based on the presence or absence of the vehicle speed pulse.

  Also, in the above, as an example of processing in which the processing contents differ between the case of the single vehicle mode and the case of the four wheel mode, navigation with display of a map figure is performed in the four wheel mode, whereas characters and An example of navigation by changing the size or color of the arrow or blinking these displays has been shown. In addition to this, as a process unique to the single-vehicle mode, the map display only at the neutral time, the display screen A process for increasing the brightness, a simplified message display, an enlarged display of operation buttons, a process for changing the color scheme, a minimum display, and the like can be considered.

  The map display only in the neutral mode allows the map display only when the transmission gear is in the neutral position, and does not display the map in other cases, but only a simplified display by turn-by-turn as shown in FIG. Is something to do. According to this, since the map is not displayed when the single vehicle is traveling, safe driving is ensured.

  The process for increasing the brightness of the display screen is a process for making the display screen brighter by increasing the brightness of the backlight compared to the four-wheel mode. In the case of a single vehicle, the display device 18 often displays in a brighter environment than the interior of a four-wheeled vehicle, so it is often difficult to see unless the display screen is brighter than in a four-wheeled vehicle. Therefore, in the single vehicle mode, by increasing the brightness of the display screen, the display on the display device of the navigation device mounted on the single vehicle can be easily seen.

  The simplified message display means that the message displayed on the display device 18 is expressed in a simpler and shorter expression than in a four-wheeled vehicle. By simplifying the message, the navigation device can display characters constituting the message larger, and the driver can instantly recognize the message.

  The enlarged display of the operation buttons and the like means that the display size of the operation buttons and the like on the display device 18 is larger than that in the four-wheel mode. By magnifying and displaying the operation buttons and the like, the driver of the single vehicle can recognize the operation buttons and the like instantly, and can operate the operation buttons even with a hand wearing a glove without erroneous operation.

  The process of changing the color scheme means that the color scheme for each graphic element displayed on the display device 18 is different from that in the four-wheel mode. For example, by changing the color scheme in single-vehicle mode to one that increases the contrast between graphic elements compared to the case of four-wheel mode, the driver of a single vehicle can recognize each graphic element more quickly and reliably. Will be able to.

  The necessary minimum display means that the number of messages and graphics displayed on the display device 18 is reduced as compared with the case of the four-wheel mode, and only important and carefully selected items are displayed larger. As a result, the driver of the single vehicle can concentrate on the driving operation without depriving the attention of information that is not very important.

  Moreover, although the example which performs navigation by the display in the display apparatus 18 was shown in the above, you may make it perform navigation by the audio | voice output using the audio | voice output means 17 instead of this or in addition to this.
