Description

  The present invention relates to a portable navigation device and a program.

  2. Description of the Related Art Conventionally, a navigation device having a function of performing a route search (route search) to a destination and guiding a guidance route according to a search result has been proposed. The navigation device displays a map around the current location of the host vehicle on the screen and superimposes and displays a current location mark indicating the current location of the host vehicle on the map. And the display of a screen is updated at any time with the change of the present location of the own vehicle.

  Further, when the departure point and the destination are set by the driver (user), the navigation device searches for the optimum route from the departure point to the destination using the map data. Then, the optimal route is displayed on the screen together with the current location mark.

  In recent years, among navigation devices on the market, there is a device called a PND (Portable Navigation Device) that can be used not only in a car but also carried. The PND generally includes a mode for use in a vehicle (hereinafter referred to as a car mode) and a mode for use when carried (hereinafter referred to as a mobile mode).

  As a technique similar to the above-mentioned PND, for example, in Patent Document 1, the specification of the device is changed regardless of whether the electronic device is connected directly to the information processing device or indirectly through another communication device. Techniques that can be dealt with without doing so are disclosed. That is, either when the mobile phone terminal device is directly connected to the information processing device fixedly mounted on the vehicle, or when the mobile phone terminal device is connected indirectly via the wireless communication device. However, it is possible to perform communication without being aware of the difference in the communication interface.

  Further, for example, Patent Document 2 discloses a technique that can be used properly between a mobile phone device and a car phone device according to the situation without performing complicated procedures. In other words, when a user owns both a mobile phone device and a car phone device, the same telephone number is set for both phone devices, and the user selects which phone device to use depending on the situation. In a system that can be arbitrarily selected, for example, the above procedure is not performed every time when getting on / off, but it is possible to automatically select according to the situation.

JP 2004-128644 A JP 2001-197560 A

However, an apparatus having a function of selecting the above-described portable mode by an arbitrary operation by the user has not been commercialized at present.
Further, the PND can be removed from the chassis inside the vehicle and used at any time. However, if the PND is automatically switched to the portable mode at the time of removal, a functional inconvenience occurs. For example, when the PND is removed and used for taking a break in the service area while driving on a highway in highway mode, unnecessary IC (interchange) guidance, signs, etc. are displayed, which hinders guidance. For example, in the audio mode, if the PND is removed and the mode is switched to the map mode, the name of the song being played cannot be grasped.

  In order to deal with these problems, means for determining whether the PND is in the vehicle or outside the vehicle by performing regular communication within a specific range with the in-vehicle housing has been considered.

  However, when regular communication is performed with the in-vehicle housing, it is necessary to establish constant communication, and from the viewpoint of design, it is necessary to select a frequency and consider power consumption. In addition, other wireless communications represented by Bluetooth (registered trademark) may be affected, and there is a problem in actual use.

  An object of the present invention is to provide a portable navigation device and a program for switching operation modes based on user operations.

  The invention described in claim 1 is made to achieve the above-described object, and operates in either a vehicle mode for use in a vehicle or a portable mode for use in a vehicle. A portable navigation device configured to be attachable to and detachable from a body, comprising: a display unit; an operation unit; an attachment / detachment detection unit for detecting whether the portable navigation device is attached to a housing in the vehicle; and the attachment / detachment detection. When it is determined that the portable navigation device has been removed from the casing inside the vehicle based on the detection signal from the unit, the display unit displays that the switch to the portable mode is possible, and the operation unit is And a controller that switches to the portable mode when an instruction to switch to the portable mode is input.

  According to a second aspect of the present invention, in the portable navigation device according to the first aspect, the control unit is configured such that the portable navigation device is mounted on a housing in the vehicle based on a detection signal from the attachment / detachment detection unit. When it is determined, the display unit displays that it is impossible to switch to the portable operation mode.

  The invention according to claim 3 is mounted on a portable navigation device that operates in either a vehicle mode for use in a vehicle or a portable mode for use in a vehicle and is configured to be detachable from a housing inside the vehicle. The portable navigation device includes a display means, an operation means, an attachment / detachment detection means for detecting whether or not the portable navigation device is attached to a housing inside the vehicle, and the portable navigation device based on a detection signal from the attachment / detachment detection means. When it is determined that the vehicle has been removed from the casing in the vehicle, the display means displays that the switch to the portable mode is possible, and an instruction to switch to the portable mode is input via the operation means. In this case, the program is made to function as control means for switching to the portable mode.
