Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device mounted on a moving body such as an automobile.

[0002]

2. Description of the Related Art In recent years, a so-called navigation device for mounting on a moving body such as an automobile for grasping traffic conditions has become widespread. When such a navigation device is mounted on a mobile object such as a car, the current position can be displayed so as to be superimposed on a map image, or a suitable route to a destination can be displayed on the map image.

[0003] Some navigation devices have a function of storing the running locus of the user in a memory. Such a navigation device can call out the traveling locus after the drive ends. In addition, for example, it is also possible to easily mark a point (a tourist spot, a store, or the like) where the user has dropped in during a drive while checking the traveling locus. Then, when the user revisits the point, by displaying the marked point and the map image from the memory, the position desired to be revisited can be confirmed.

[0004]

In order to store the running locus of the user in a memory or the like as described above, a so-called non-volatile memory is required. However, the non-volatile memory is relatively expensive. Therefore, at present, there is no device having such a large capacity. For this reason, it is not possible to store all past running trajectories in the memory.

[0005] For this reason, when a user tries to find and mark a store that suddenly dropped in one month ago, for example, the information on the running locus at that time may already be deleted from the memory. In this case, the user searches for the target point only based on the memory, but at that point, it is difficult to mark the target point because the user's memory has already been ambiguous.

[0006] Even if the running locus is stored in the memory, the work of searching for and marking a target point from the running locus and the memory of the user is relatively troublesome for the user. It is quite possible that the mark function is not used effectively.

The present invention has been made in view of such a point, and provides a navigation device which can store information of a place where a user has dropped in and can easily search for a target point from the stored information. The purpose is to do.

[0008]

In order to achieve the above object, a navigation device according to the present invention is configured as follows. In other words, positioning means capable of measuring the current position of the moving body, detecting means for detecting that the moving body is in the stopped state, and when the stopped state detected by the detecting means has passed a predetermined time or more. It is assumed that stop history information, which is required information on the stop position at this time, is created, and the stop history information is created by including at least stop position information obtained by measuring the stop position by the positioning means. , A storage unit capable of storing one or more of the above-mentioned stop history information, and a presentation for making a presentation in a predetermined output mode based on the stop history information stored in the storage unit. Means.

That is, the navigation device of the present invention stores stop history information including at least information on a stop position at which the moving body has stopped for a predetermined time or more, and outputs the stop history information in a predetermined output mode. To be presented by This makes it possible to search for a previously visited point from the presented stop history information.

The navigation device 1 according to the present embodiment shown in FIG. 1 includes, for example, a navigation body 2, a display 3, a GPS antenna 5, an autonomous navigation unit 6, a parking detector 7, a remote commander 8, and the like.

Although a detailed configuration of the navigation main body 2 will be described later, the navigation device 1 can be used, for example, based on the map information read from the recording medium 9 capable of performing a reproducing operation therein and the current position information. Navigation information serving as a guide for a drive route, a current position, and the like of a mounted vehicle is generated and output to the display unit 3 serving as a presentation unit. Note that, in the present specification, an automobile equipped with the navigation device 1 is referred to as a host vehicle.

The recording medium 9 is, for example, a CD-ROM (Comp
act Disk-Read Only Memory, DVD-ROM (Di
gital Video Disk / Digital Versatile Disk-Read Onl
y Memory) or a read-only disc.

The navigation information output from the navigation main unit 2 to the display unit 3 mainly includes a map image read from the recording medium 9, various characters superimposed on the map image, for example, various characters of the own vehicle. It is image navigation information such as a position image indicating the current position.

The display screen section 3a of the display section 3 is composed of, for example, a liquid crystal display or the like, and displays a display image based on image information output from the navigation main body section 2. The receiving unit 3b is a receiving unit that receives command information sent from the remote commander 8. This received information is transmitted to the navigation body 2 as described later.

Although not shown here, the navigation device according to the present embodiment may be provided with an audio output unit such as a speaker. In this case, the navigation body unit 2 outputs voice navigation information such as a predetermined point (intersection), traffic congestion, right / left turn points, and wrong route directions to the voice output unit. , A warning sound or a guide sound can be output.

A GPS (Global Positioning System) antenna 5 is provided for receiving radio waves from, for example, satellite communication. The radio wave received by the GPS antenna 5 is taken into the navigation body 2 as demodulated reception data, for example, and is used to measure the current position of the vehicle as described later.

The autonomous navigation unit 6 is a part for detecting traveling information such as the traveling speed and traveling direction of the own vehicle, for example, a vehicle speed pulse detecting unit for detecting a vehicle speed pulse that changes according to the traveling speed of the own vehicle, It is composed of a gyro sensor for detecting the traveling direction of the vehicle. The travel information detected by the autonomous navigation unit 6 is output to the navigation main body 2 and used for positioning the current position of the vehicle as described later. In particular, such an autonomous navigation unit 6 is used when, for example, the vehicle enters a tunnel or the like and the GPS antenna 5 cannot receive radio waves from satellite communication.
This is suitable for grasping the current position of the vehicle.

The stop detecting section 7 is a detecting section for detecting whether or not the own vehicle is in a stopped state. For example, brake information indicating the on / off state of the side brake of the own vehicle, or an auto-matching vehicle is provided. If there is, based on gear information indicating that the gear position is set to the parking position, it is determined whether or not the own vehicle is in a stopped state.

The remote commander 8 is used for user operation of the navigation apparatus 1 of the present embodiment, and generates various operation keys, a signal generation unit for generating a command signal in response to operation of the operation key, and a generated command signal. An output unit or the like for outputting an infrared luminance modulation signal is provided, and a command output by the infrared light is received by the receiving unit 3b.

Of course, other operation means may be provided, for example, on a remote commander by radio wave transmission, a remote commander connected to the navigation main unit 2 by wire, and further on the housing of the navigation main unit 2 and the display unit 3. An operation unit or the like used may be used.

FIG. 2 is a block diagram showing the internal configuration of the navigation main body 2. As shown in FIG. In FIG. 2, a positioning unit 4 is a part that measures the current position of the own vehicle, and based on GPS reception data transferred from the interface 14 and travel information of the own vehicle, a position indicating the current position of the own vehicle. Information such as latitude / longitude information is obtained.

A ROM (Read Only Memory) 11 stores various programs for the navigation apparatus 1 of the present embodiment to execute required processing. SRAM
(Static Random Access Memory) 12 is a nonvolatile memory for storing and holding backup data. The backup data used here is used, for example, as a user memory for navigation, and usually includes mark information such as a destination and a passing point, various settings, and travel locus information. Further, in the present embodiment, the details will be described later, but when it is determined that the vehicle has been parked for a predetermined time or more,
At this time, various kinds of information on the parking position of the own vehicle are stored as parking history information.

The memory for the backup data is not limited to the SRAM 12, but may be a rewritable memory that does not require refreshing, such as a flash memory or a state in which power is not supplied. However, it is also possible to configure with a memory or the like capable of storing the contents.

DRAM (Dynamic Random Access Memor)
y) 13 is used as a work area of the program, and is used for storing drawing data and the like for generating image navigation information reproduced from the recording medium 9 by the disk driver 18.

An interface (I / F) 14 is provided for connecting an external device to the navigation body 2. In this case, the interface 14 receives the received data from the GPS antenna 5 via the terminal 30 and the traveling information from the autonomous navigation unit 6 via the terminal 31. Further, stop information indicating whether or not the vehicle is in a stopped state is input from the stop detection unit 7 via the terminal 32. The reception data from the GPS antenna 5 and the traveling information from the autonomous navigation unit 6
The data is transferred to the positioning unit 4 via the bus 20. Further, the stop information of the own vehicle is transferred to the control unit 19 via the bus 20.

The clock unit 15 measures the current date and time.
For example, it is used to display the current date and time on the display unit 30, and is also used to determine the time (date and time) when the vehicle has stopped and the time (date and time) when the stop state has been released.

The input section 16 is connected to the display section 3 via a terminal 33.
The command signal from the remote commander 8 received by the receiving unit 3b is input via the terminal 33. Then, the input unit 16 converts the input command signal into an electric signal, and then supplies the electric signal to the control unit 19 via the bus 20. Thereby, the control unit 19
Can recognize the operation of the user.

The display driver 17 generates image information for display under the control of the control unit 19 and outputs the generated image information to the display screen unit 3 a of the display unit 3 via the terminal 34. For example, the map information stored in the DRAM 13 or the positioning unit 4
An image signal indicating the current position of the own vehicle is generated based on the position information of the own vehicle measured in step (1), and is output to the display unit 3. Further, the display driver 17 can generate an image signal for displaying the parking history information stored in the SRAM 12 in a predetermined display form and output the image signal to the display unit 3. The display form of the parking history information will be described later.

The disk driver 18 is a part for reproducing map information and various information recorded on the recording medium 9 such as a CD-ROM and a DVD-ROM. The reproduced map information and the like are transferred to the DRAM 13 via the bus 20. Transferred and stored.

The control unit 19 executes necessary control for each circuit unit so that the navigation main unit 2 performs the required operation as described above.

In the navigation device 1 according to the present embodiment having the above-described configuration, when the own vehicle has been stopped for a predetermined time or longer and is considered to be in the "parked" state, various information on the parking position (see FIG. Associated information) is stored as parking history information, and a display screen based on the parking history information can be displayed and output on the display unit 3.

First, the operation of creating and storing the parking history information of the own vehicle in the navigation device 1 of the present embodiment will be described. In order for the navigation device 1 of the present embodiment to create and store parking history information, first, it is configured to detect whether or not the own vehicle is in a stopped state. As a method of detecting the stop state of the vehicle,
Although various methods are conceivable, as described above, it is possible to detect the stop state of the host vehicle based on, for example, the brake information and the gear information from the stop detection unit 7.

When the own vehicle is in a stopped state, the position information measured by the positioning unit 4 becomes substantially constant, and vehicle speed pulse information indicating the running speed of the own vehicle detected by the autonomous navigation unit 6 is obtained. It is conceivable that the stop state is detected from such information. Furthermore,
When the vehicle is stopped, the engine of the vehicle is stopped. Therefore, when the key of the vehicle is in the power-off position, that is, when the main power of the navigation device 1 is turned off, it is determined that the vehicle is stopped. Is also possible. When detecting the stop state of the vehicle based on the current position information measured by the positioning unit 4 and the vehicle speed pulse information detected by the autonomous navigation unit 6, the parking detection unit 7 does not always need to be provided.

Then, when it is detected that the own vehicle is in a stopped state by any of the above stop detection methods, it is determined whether or not the stop time of the own vehicle is longer than a predetermined time. In other words, for the current stop, a distinction is made between a mere stop such as a traffic jam or a traffic light wait and parking for a certain purpose (for example, sightseeing, eating, shopping, etc.). If the stop time has continued for a predetermined time or more, parking history information is created and stored based on various information on the parking position.

The creation and storage operations of the parking history information of the navigation apparatus 1 according to the present embodiment as described above are obtained by the processing operations executed by the control unit 19 provided in the navigation main unit 2. Thus, a flowchart of FIG. 3 shows a processing operation of the control unit 19 for realizing the operation of the navigation device 1 described above.

In this case, first, in step S11,
The control unit 19 detects whether or not the own vehicle is in a stopped state based on the detection information obtained by the above-described stop detection. When it is determined that the current state is the stop state, the process proceeds to step S12, and the current time (date and time) measured by the clock unit 15 is set as the stop start time, for example, in the SRAM 1
2 (or the DRAM 13).

Then, in the next step S13,
The control unit 19 waits until the stopped state of the own vehicle is released, and proceeds to step S14 when it is determined based on the stop detection information that the previous stopped state has been released. In step S14, the parking time of the own vehicle is obtained from the stop start time previously stored in the SRAM 12 and the current time at which the stop state has been released, and the parking time is equal to or longer than a predetermined time set in advance. Is determined.

Here, for example, if the parking time of the own vehicle is equal to or longer than a predetermined time, the stop of the own vehicle so far is regarded as a purposeful parking. Therefore, the next step S
In step 15, control is performed to create parking history information based on the position information of the parking position (parking position information) and various accompanying information related to the parking position, and to store it in the SRAM 12. Here, the position information of the parking position is obtained in step S
It is sufficient to use the current position information obtained by the positioning unit 4 during the period in which the processes from S11 to S13 are performed. Further, the accompanying information attached to the parking position information will be described later.

When it is determined in step S14 that the parking time of the own vehicle is within the predetermined time, it is determined that the detected stop state is merely a stop such as a traffic jam or a signal waiting.
The processing operation ends without storing the parking history information of the parking position in the SRAM 12.

Here, an example of the contents of the parking history information stored in the SRAM 12 will be described. FIG.
2 shows an example of parking history information stored in No. 2; As shown in this figure, the structure of the parking history information stored in the SRAM 12 includes parking history information 41, 42,
43, 44, 45,..., It has a table structure in which a plurality of parking history information is arranged. Therefore, here, a set of one or more pieces of parking history information stored in the SRAM 12 is referred to as a parking history information table 40.

As the individual parking history information in the parking history information table 40, first, parking position information of the own vehicle is provided. Subsequently, parking time information (including date and time) corresponding to when the parking position information is obtained and parking time (period) information are provided. The parking time and the parking time can be regarded as time information corresponding to when the parking position information is obtained. Further, parking number information indicating the number of times of visiting the parking position indicated by the parking position information, and category information which is information corresponding to a point including the parking position and an area are provided. Furthermore, here, for each parking history information,
Expiration date information for setting an expiration date to be stored in the SRAM 12 is provided. That is, the parking history information is formed by the parking position information and various accompanying information that allows the user to easily search for the parking position later.

As a specific example, in the parking history information 41 in the parking history information table 40 shown in FIG. 4, regarding the parking position information, "135 @ 35'47" / "35 @ 2"
3'55 "" as indicated by latitude and longitude. For parking time information, refer to "'98 / 02 /
24, and "13:34:45". The parking time information is indicated by the time length, for example, "00:55:25". In this case, the number of times of parking information is "5", which indicates that the vehicle has been parked five times with respect to this position. The category is "restaurant".
Is shown. Further, the expiration date is set such as "'02 / 24/99".

Here, as described above, the position information measured by the positioning unit 4 is used as the parking position information (longitude information / latitude information). As the parking time information, for example, a start time when the own vehicle is detected to be in a stopped state by the stop detection information from the stop detection unit 7 is used. Note that the parking time information does not necessarily need to use the start time at the time of detecting the stop, but may be any time corresponding to a certain point in the parking period of the own vehicle.

The parking number information is obtained based on whether or not parking history information indicating substantially the same parking position as that of the newly stored parking history information is already stored in the SRAM 12. For example, if parking history information indicating substantially the same parking position does not exist in the SRAM 12, “1” is written as new parking history information as parking number information.

When parking history information indicating substantially the same parking position already exists in the SRAM 12, a value obtained by adding "1" to the number of times of parking is written as the number of times of parking. In this case, leave the new parking history information
Prior to this, the parking history information of the same parking position written in the parking history information table 40 may be deleted.

As the category information, for example, when a category (including a name or the like) corresponding to the parking position is read from the storage medium 8 and stored in the DRAM 13, the category information is written. On the other hand, DRA
When no category information is stored in M13, the parking history information in which no category information is written is stored in the SRAM1.
2 is stored. However, in the present embodiment, it is possible for the user to arbitrarily set and add the category information later, in case that the category information is not written in the parking history information, for example. Note that a method of additionally writing various information written in the parking history information will be described later.

As information on the expiration date, for example, a date obtained by adding a predetermined period (one year in this example) to the parking date and time is written as the expiration date, and after the expiration date, the parking history information is deleted. Is done. When the expiration date is provided in the parking history information in this manner, an increase in the parking history information stored in the SRAM 12 can be suppressed,
The retrieval of the parking history information is facilitated, and the capacity of the SRAM 12 allocated for storing the parking history information can be reduced.

In this embodiment, the information on the expiration date is set for each parking history information. However, all the parking history information stored in the parking history information table 40 is collectively collected at a predetermined date and time. It can be erased. Such batch erasing is performed by the navigation device 1.
However, this is effective when the vehicle is installed in a car used by an unspecified number of drivers, such as a rental car.If an expiration date is set according to the number of days the driver has used, the parking history information table can be set for each driver used. 40 can be created.

The various information contents stored in the parking history information table 40 shown in FIG. 4 are merely examples, and other information contents may be set corresponding to the position information indicating the parking position. Things. Further, it is not always necessary to write all of the various information contents shown in FIG. That is, the parking position information is indispensable, and which of the remaining information is included as the parking history information may be determined according to actual usability or the like.

As described above, the parking history information stored in the navigation device 1 of the present embodiment is stored in the display portion 3b of the display unit 3 when the user performs a required input operation using the remote commander 8. It can be displayed as a history screen. Then, when the user performs an input operation such as selecting desired parking history information from the parking history screen while viewing the parking history screen, a map image of a point corresponding to the parking history information is displayed on the display unit 3. Have been able to.

FIGS. 5 and 6 are views showing an example of a display image displayed on the display unit 3 in the navigation device 1 according to the present embodiment. With reference to FIGS. 5 and 6, an operation from searching for a point where the user has stopped before to displaying the point will be described. FIG. 5A is a diagram illustrating an example of a display screen displayed on the display screen unit 3a of the display unit 3 when the navigation device 1 according to the present embodiment operates as a normal navigation function. This FIG.
On the display screen 50 shown in FIG. 5, a map image corresponding to the current position of the own vehicle is displayed, and its running locus is displayed by a black circle “●”.

Here, for example, if the user performs a necessary input operation for searching for a previously visited point, a history menu screen 51 is superimposed on the map image on the display screen 50. . This history menu screen 51 is a so-called GUI (Graphical User Interface).
e) An operation screen having functions, and a selection area 52 for history display is provided as a history menu.

Next, the history menu screen 51 is displayed by the user.
Is performed, the sort operation screen 61 is superimposed on the map image on the display screen 50 as shown in FIG. 5B. The sorting operation screen 61 is also an operation screen having a GUI function, and has selection areas corresponding to various types of information written in the parking history information as selection areas.

Here, the sort operation screen 61 is displayed by the user.
If the operation of selecting the hatched category area 62 is performed from among the selected areas, the parking history information sorted by the category information is superimposed on the display screen 50 as the history information screen in the present embodiment. To be displayed.

FIG. 6A shows an example of a history information screen on which parking history information sorted by category information is displayed. In the example shown in FIG. 6A, the parking history information is “restaurant”, “sightseeing spot”, “convenience store”.
Are displayed in the order of the history information screen 63.
“Convenience store” written as category information
Is an abbreviation for convenience store. Note that, for example, if the user selects a parking position, parking time, parking time, and parking number displayed area on the sorting operation screen 61,
Parking history information sorted in descending order or ascending order according to the respective information is displayed as a history information screen 63.

Therefore, the user looks at the parking history information sorted and displayed on the history information screen 63 shown in FIG. 6A, and searches for a previously visited point. Here, for example, when the user finds the destination point from the parking history information displayed on the history information screen 63,
An operation of selecting the parking history information is performed. The history information screen 63 also has a GUI function.

For example, when the user selects the parking history information 64 shown by hatching in FIG. 6A, the display screen 50 of the present embodiment displays the following information as shown in FIG.
For example, a map image in which the destination point is indicated by the target mark 65 at the center thereof is displayed. Therefore, according to the navigation device 1 of the present embodiment, the user can grasp the previously visited point by the map image shown in FIG. 6B and the target mark 65.

Although the expiration date is not shown as a sort item in the sorting operation screen 61 and the history information screen 63 in FIGS. 5 and 6, actually, the sorting by the expiration date is performed by sorting parking time. Since it can be seen that the result is the same as the result, the sort item is omitted here. However, this expiration date may be displayed as a sort item if necessary for some convenience.

The display operation of the navigation device 1 according to the present embodiment as described above is also executed by the control unit 19. FIG. 7 is a flowchart showing a processing operation of the control unit 19 for realizing the above-described display operation.

As the processing shown in this figure, first, in step S21, the presence or absence of an input operation from the remote commander 8 is determined. When it is determined that the input operation has been performed, the process proceeds to step S22. In step S22, it is determined whether the input operation is a history request operation. If the input operation is a history request operation, the process proceeds to step S23. If the input operation is not a history request operation, the process returns to step S21 and the input operation is performed again. Waiting for you. Here, the history request operation refers to an operation of displaying the history menu screen 51 on the display screen 50 shown in FIG. 5A and an operation of selecting the history display area 52 from the displayed history menu screen 51. ing.

In the next step S23, the control unit 1
9 is a sort operation screen 61 on the display screen 50 of the display unit 3.
Is performed to superimpose and display, and the process proceeds to step S24. In step S24, for example, when it is determined that one of the selection areas of the sort operation screen 61 is selected by the user, the process proceeds to step S25, and otherwise, the process returns to step S23 to execute the process of displaying the sort operation screen 61. While waiting, a selection area on the sort operation screen 61 is selected.

In step S 25, according to the information content of the selected area selected on the sort operation screen 61,
The parking history information stored in the RAM 12 is sorted, and in the subsequent step S26, the sorted parking history information is displayed as a history information screen 63 on the display screen 50 of the display unit 3.
Is performed so as to superimpose the displayed information.

If the user selects the parking history information on the history information screen 63 in the next step S27, the process proceeds to step S28, and in step S28, the map image of the point corresponding to the selected parking history information Is displayed on the display screen 50. Also,
In step S27, the user inputs the history information screen 6
If the parking history information of No. 3 has not been selected, step S
While performing the process of displaying the sorted parking history information, which is the process of 26, the process waits until a parking history information selecting operation is performed.

By performing such processing operations by the control unit 19, the navigation device 1 of the present embodiment can display the display images as shown in FIGS. 5 and 6 on the display unit 3. .

In the present embodiment, as described above, an expiration date is set for the parking history information stored in the SRAM 12, and the parking history information for which the expiration date has passed is set. Is to be erased (deleted).

FIG. 8 shows a control section 19 for realizing the operation of erasing the parking history information after the expiration date as described above.
5 is a flowchart showing the operation processing of FIG. Note that such an erasing processing operation is performed as one of the initial setting operations performed when the main power supply of the navigation device 1 of the present embodiment is turned on, for example.

In this case, first, in step S31,
The control unit 19 searches (checks) the expiration date information of each parking history information with reference to the parking history information table stored in the SRAM 12. Next, in step S32, the control unit 19 compares the searched expiration date of each piece of parking history information with the current date and time, and if there is any parking history information whose expiration date has passed, the process proceeds to step S33. Then, in step S33, a process of deleting the parking history information whose expiration date has elapsed from the parking history information stored in the SRAM 12 is executed.

It is natural that the user may not want to delete past parking history information even if the expiration date has passed. Therefore, although detailed description is omitted, in order to cope with such a case, an expiration date (including, for example, a setting of no expiration) can be individually set for each parking history information in accordance with a user operation. Is also good. Further, the default expiration date (period) may be set arbitrarily by the user.

By the way, when creating the parking history information, the navigation device 1 of the present embodiment creates the parking history information from the position information indicating the parking position and various kinds of information relating to the parking position. . However, as described above, if the category information indicating the parking position is not recorded on the recording medium 9 as one of the map information, for example, the category indicating the parking position is used when creating the parking history information. It is naturally impossible to create parking history information including information.

Even when the category information is included in the parking history information, the category information written in the parking history information and the actual category may not match due to a change in the store or the like. For this reason, in the present embodiment, it is possible to add or rewrite (update) the information included in the parking history information already stored in the SRAM 12.

FIG. 9 is an explanatory diagram of the operation of updating the information content of the parking history information. In this example, a case where category information is added to the parking history information will be described as an example. For example, when performing the additional recording of the parking history information already stored in the navigation device 1, the user uses the remote commander 8 to
An operation for displaying the history display screen 63 as shown in FIG. 9A is performed. Then, the history information screen 63
Is displayed, the parking history information 64 in which the hatched category is not written is selected from the history information screen 63.

Here, for example, when the user performs a required operation for inputting a category in a state where the parking history information 64 is selected, in this embodiment, FIG.
As shown in (b), the category information list screen 71 is superimposed on the display screen 50. Therefore, the user selects the category information corresponding to the selected parking history information 64 from the category information list screen 71.

For example, when the user performs a selection operation to select the cross-hatched “restaurant” area 72 from the category information list screen 71, the selected category is first selected from the history information screen 63. As shown in FIG. 9C, the parking history information 64 to which the selected category “restaurant” has been additionally written is added as the category information of the parking history information 64.
Will be displayed as

In the above description, the category selected from the category information list screen 71 is added to the parking history information. For example, a character input screen or the like is displayed on the display screen 50 so that the user can freely select the category or the like. Alternatively, the name of this category may be input. Also,
In the above description, an example of the additional writing operation in a case where the category information is not written has been described with respect to the category information, but, for example, when the category information has already been written in the parking history information, the same as above It is sufficient to rewrite the category information according to the operation procedure described above.

FIG. 10 is a flowchart showing the processing operation of the control unit 19 for updating the parking history information described above. In this case, the control unit 19 first determines in step S41 whether or not there is an input operation from the remote commander 8. When it is determined that the input operation has been performed, the process proceeds to step S42. In step S42, it is determined whether or not the input operation determined in step S41 is an input operation for inputting category information. If the input operation is an input operation for category information, the process proceeds to step S43. Here, the category information input operation is an input operation for displaying the history information screen 63 on the display screen 50 and a selection operation for selecting the parking history information 64 in which no category is written from the history information screen 63. It is assumed to point to.

Then, in the next step S43,
Control for displaying the category information list screen 71 on the display screen 50 is executed, and the process proceeds to step S44. Step S4
In step 4, it is determined whether or not any category has been selected from the category information list screen 71. If any category has been selected, the process proceeds to step 45. On the other hand, if no category is selected in step S44, the process returns to step S43 and waits until a category selection operation is performed while displaying the category information list screen 71. Then, in the next step S45, control is performed to add or rewrite (update) the category selected from the category information list screen 71 in the parking history information. Then, in a succeeding step S46, the control unit 19
Executes the control of superimposing and displaying the selected category information on the display screen 50 as the history display screen 63 based on the updated parking history information 64.

In the above description, the case where the category information is updated has been described as an example. However, other accompanying information such as expiration date information can be updated by the same processing.

Further, in the above-described embodiment, for example, the display relating to the parking history information shown in FIGS. 5 and 6 is merely an example, and the display form for presenting the data content as the parking history information may be other forms. There are various conceivable things. Further, in the above embodiment, the information presentation based on the parking history information is performed by the image display. However, in some cases, the information presentation based on the parking history information may be presented by voice. Also,
Information presentation based on the parking history information may be performed by using both image display and sound output. Here, when the presentation of the parking history information is performed by the image display and the sound output, for example, the presentation of the basic parking history information is performed by the image display as shown in FIGS. After the target mark searched for is displayed as shown in FIG. 6B, various types of information (for example, a category, the number of times of parking, etc.) attached to the position information as parking history information are displayed. Information) may be guided by voice output.

In the present embodiment, the case where the navigation device 1 is mounted on a car has been described as an example. However, the present invention is also applicable to a navigation device mounted on a ship or carried by a person. Can be.

As described above, the navigation device according to the present invention detects the stop state of the moving object and, when the stop state is set for a predetermined time or more, stops the movement history information including the stop position information at that time. It is created and stored. Then, based on the stored stop history information, the stop history is presented. The user can search a previously visited point from the presented stop history information. With such a configuration, for example, the user does not have to display the travel locus later and perform the marking by relying on his or her own memory. In addition, the data of the traveling locus has a relatively large data amount, and it is difficult to store many past traveling loci in consideration of the memory capacity.
In the present invention, since the stop history information is stored separately from the traveling locus data, it is possible to store a large number of past stop history information even with a relatively small memory capacity. It becomes possible.

Further, according to the present invention, since the stop history information is presented by display, it is possible to visually present a target point to the user. It is possible to easily perform a search for a destination or the like by using.

In addition to the stop position information, the stop history information includes, as accompanying information, information relating to the time at which the moving object has been stopped there, the number of stops, and the area corresponding to the stop position. Relevant information,
A structure with an expiration date or the like can be used. Then, if such stop history information is presented, a target point can be searched for by referring to such accompanying information.

Further, according to the present invention, according to the operation of the user,
It is possible to update (including additional information) the accompanying information and the like in the already stored stop history information, but this makes it possible to obtain, for example, more complete stop history information for the user.

Further, in the navigation apparatus of the present invention, the sorting means can sort the stationary history information for each information unit forming the stationary history information. Can be searched. As described above, in the present invention, improvement in easiness for search is also considered.

Furthermore, when the stop history information includes the expiration date information, the navigation device of the present invention deletes the stop history information whose expiration date has passed. As a result, even if the user does not perform the deletion operation, the stop history information can be automatically prevented from increasing more than necessary, and the memory capacity allocated for actually storing the stop history information is small. It will be done.
