Description

    The present invention relates to a navigation device that performs a route search based on a search condition input by a user.

  In recent years, people's health awareness has increased, and all kinds of health foods and health goods are lined up in stores, and they manage their own health by purchasing these foods and goods. The number of people is increasing.

  In addition, the number of people who manage their own health through daily activities such as walking and running is increasing.

  In this way, the background to the increase in people's health awareness is that the number of people suffering from lifestyle-related diseases has increased in recent years due to disturbances in eating habits. It is obesity.

  The reason why this obesity has increased is that drinking and eating out, or increased use of convenience stores, etc., and leaving this obesity is said to lead to impaired liver function It has become a serious problem.

  In order to eliminate this obesity, it is considered effective to perform daily moderate exercises such as walking and running, and development of products for people who perform walking and running in this way Is also being promoted in the field of portable electronic devices.

  In Patent Document 1 (Japanese Patent Laid-Open No. 2004-109100), it is possible to calculate the calorie consumption accompanying movement by using a geodetic meter and map information that can measure the current position and altitude, and the target calorie consumption. A navigation system has been introduced that can present a route to achieve quantity.

The navigation system of Patent Document 1 is composed of a mobile terminal and a server,
When the current location and altitude are obtained in the mobile terminal and the current location information obtained in the mobile terminal is transmitted to the server, a route to the destination is generated in the route generation unit in the server, and is generated in the route generation unit. The route is transmitted to the mobile terminal and displayed on the display unit of the mobile terminal.

  Further, the calorie consumption calculation unit in the portable terminal calculates the calories consumed in the route generated in the route generation unit, and the calculated calories are displayed on the display unit in the portable terminal.

Thereby, the user can grasp | ascertain how many calories are consumed in the path | route to the destination which he input.
JP 2004-109100 A

  In the above-mentioned patent document 1, the calories consumed in the route to the destination input by the user is displayed on the display unit. Therefore, when the user performs walking or cycling, the route to the destination input by the user is displayed. How many calories are consumed in the route, and, in addition, the route to which the calorie consumption is the lowest among the routes to the input destination, or the route where the user achieves the target calorie consumption It is also possible to select a plurality of route searches, such as a search for a different route from a route that has been generated once, and a route that is different from the route once generated.

  However, in Patent Document 1, when there is a difference between the calorie consumption on the route desired by the user and the calorie consumption targeted by the user, the user walks on a route different from the route desired by the user. So, if you have plenty of time on holidays etc., and you are a person who is mainly walking or cycling, there is no problem, but it is an invention that considers those who are thinking to find a work interval and do walking I can't say that.

  Patent Document 1 is composed of a mobile terminal and a server, and is established when the mobile terminal and the server exchange data by communication.

  The navigation device of the present invention has been made in view of the above problems, and does not require a complicated configuration such as a mobile terminal and a server, and it is difficult to make time for exercise in daily life, such as a busy office worker. Therefore, it is an object of the present invention to provide a navigation device capable of presenting a user with a route for performing a walking in a free time regardless of location.

In order to solve the above problems, a navigation device of the present invention includes a map data storage means for map data needed for route search is stored, and route search means for searching for a route from a departure point to a destination, moving An input means for inputting time, a current position detecting means for detecting a current position every predetermined time, a moving speed is calculated based on the current position detected by the current position detecting means, and the calculated moving speed Speed calculating means for calculating the average moving speed based on the above, storage means for storing the average moving speed calculated by the speed calculating means, and control means, wherein the input means is displayed on the display means. operation is icon, the control unit, a minimum time it takes to the destination which is calculated on the basis of the average moving speed stored in the distance and the storage means to the destination As the reference time, on said display means, and the reference period,
The operation icon indicating a plurality of times obtained by adding a predetermined time to the reference time is displayed, and the route search means searches for a route whose travel time from the departure place to the destination is the time input from the input means. It is characterized by doing.

The navigation device according to the present invention provides the display unit with the reference time, with the minimum time taken to the destination calculated based on the distance to the destination and the average moving speed stored in the storage unit as a reference time. And the operation icon indicating a plurality of times obtained by adding a predetermined time to the reference time, and the route search means is a route whose travel time from the departure place to the destination is the time inputted from the input means. Therefore, when the user freely sets the walking time using the numeric keypad or the like, the time that is impossible as the walking time from the current position to the destination (for example, the walking time is set to 15 on a route that takes at least 20 minutes). The problem of setting minutes and settings) can be solved.

Specific examples of the present invention will be described below with reference to examples and drawings. However, the examples shown below are
The navigation device for embodying the technical idea of the present invention is illustrated, and is not intended to specify the present invention to this navigation device, but navigation according to other embodiments included in the scope of the claims. It is equally applicable to devices.

  First, the configuration of the navigation device will be described with reference to the block diagram of FIG.

  The input means 10 is a switch for the user to operate the navigation device 1 and can be operated by touching a button provided on the navigation device 1 main body or an operation icon displayed on the display means 11 described later. It may be a touch panel.

  The display unit 11 is configured by an LCD or the like and displays a map, a guidance route, and the like in route guidance, and also functions as an input unit as described above.

  The speaker 12 is voice output means for outputting route guidance based on voice data among route guidance performed by the navigation device 1.

  The current position detection means 13 is for specifying the current position of the navigation device 1 and is based on outputs from a GPS sensor (not shown), a gyro sensor (not shown), a vehicle speed sensor (not shown), etc. The position is specified.

  The map data storage unit 14 stores map data used for route guidance performed by the navigation device 1.

  The navigation device 1 functions as a navigation device for walking, and does not store map data with the roadway as the main road, unlike a normal navigation device mounted on an automobile, and is used by pedestrians for movement In addition to storing data such as sidewalks and overpasses that are the main roads to be used, in addition, when the user who has this navigation device 1 moves using transportation such as trains and buses, Train route information and bus route information are also stored.

  The route search means 15 searches for a route from the current position detected by the current position detection means 13 to the destination input by the user via the input means 10.

  The speed calculation means 16 possesses the navigation device 1 based on the distance to the destination input by the user via the input means 10 and the current position detected by the current position detection means 13 every predetermined time. The moving speed of the pedestrian is calculated. The speed calculating means 16 also calculates the average moving speed of the moving speed calculated every predetermined time, and the calculated average moving speed is stored in the storage means 17.

  The average moving speed stored in the storage means 17 stores the moving speed and the average moving speed calculated in the speed calculating means 16 each time, as well as the average calculated in the speed calculating means 16 in the previous walking mode. The movement speed is also memorized.

  The control means 18 controls each part in the navigation apparatus 1 based on a control program stored in a ROM (not shown).

  Note that the route search performed by the route search means 15 in the navigation device 1 includes a normal route search mode in which the shortest route from the current position to the destination is searched, and a search in the route search by the user via the input means 10. There is a walking mode that is executed when a condition is entered.

  The walking mode is a mode executed when the user wants to walk in consideration of health in the route from the current position to the destination. When a desired walking time (for example, 30 minutes) is input, the route search means 15 searches for a route that arrives at the destination over 30 minutes.

  At this time, the route search means 15 is based on the distance to the destination input by the user via the input means 15 and the average moving speed in the previous walking mode stored in the storage means 17. Is searched for a route arriving at the destination in the desired walking time inputted by.

  In the above embodiment, the normal route search mode is described as searching for the shortest route from the current position to the destination. However, the present invention is not limited to this. For example, a point to be avoided on the route from the current position to the destination. (For example, a point where a traffic jam is expected) can be registered, or a point (for example, a convenience store) that the user wants to stop by before reaching the destination can be registered.

  Next, the control operation of the control means 18 in the portable navigation device 1 will be described with reference to the flowchart of FIG.

  When the user makes a destination input request via the input means 10 (step S1), it is next detected whether or not the walking mode is set (step S2).

  In the process of step S1, when there is no destination input, the system waits until the destination is input by the user.

As shown in FIG. 3, the setting of the walking mode is performed by a user searching for a route search in the navigation device 1 by pressing a selection icon for selecting a walking mode provided in the destination setting screen. The mode is set to walking mode.
As shown in FIG. 3, the walking mode is set with an icon for selecting the walking mode as shown in FIG. 3, and whether or not the walking mode is set as shown in FIG. A message asking the user may be displayed superimposed on the destination setting screen.

  When the walking mode is set in the process of step S2, the user inputs a desired destination using the operation icon displayed on the destination setting screen shown in FIG.

  When the destination is input by the user, the display unit 11 displays a setting screen for requesting the user to set the walking time as shown in FIG. 6, and the user displays the display shown in FIG. The desired walking time is set by pressing the selection icon displayed on the means 11 (step S3).

  FIG. 6 shows a walking time setting screen set by the user in step S3. In FIG. 6, three selection icons for selecting the walking time are displayed. , 20 minutes, 30 minutes, 40 minutes.

  This time calculation method is the purpose calculated from the distance from the current position to the destination input by the user via the input means 10 and the average moving speed in the previous walking mode stored in the storage means 17. With reference to the minimum time required to reach the ground, a predetermined number, for example, a number obtained by adding 10 minutes to the minimum time required to reach the destination is displayed on the display means 11 as a setting icon.

  The reason for taking such a calculation method is that if a method of allowing the user to freely set the walking time using a numeric keypad or the like is taken, the time that is impossible as the walking time from the current position to the destination (for example, the minimum This is because the walking time may be set to 15 minutes in a route that takes 20 minutes.

  However, when the user freely sets the walking time using the numeric keypad, only the time longer than the minimum time required for the destination described above can be set.

  Further, when the walking time is set by the user, the search in the route search means 15 does not necessarily match the walking time set by the user because of the relationship with the road data in the set route. In such a case, a route having a walking time closest to the walking time set by the user is searched for, and the fact that the times do not match is displayed on the display means 11 or voice notification is given from the speaker. Good.

  In the process of step S3, when the walking time is set by the user, the route searching means 15 calculates a route arriving at the destination set by the walking time set by the user (step S4).

  In the process of step S4, the route search means 15 uses the map data stored in the map data storage means 17, the distance to the destination set in the process of step S1, and the average moving speed stored in the storage means 17. Based on the above, a search is made for a route arriving at the destination in the walking time input by the user.

  Although the movement speed used for the route search in the route search means 15 has been described as being stored in the storage means 17, the present invention is not limited to this, and the user inputs the movement speed via the input means 11. You may take a method.

  Further, the route searched by the route search means 15 in the process of step S4 is not necessarily one, and there may be a plurality of searched routes. In such a case, the search means 11 searches for the route. All the routes are displayed, and the user can freely select a route (step S5).

  When there is only one route searched in the process of step S4, the process proceeds to the process of step S6 without performing the process of step S5.

  In the process of step S5, when a route is selected by the user, route guidance is started (step S6).

  When the route guidance is started in the process of step S6, it is next detected whether or not the destination has been reached (step S7), and if the destination is reached, the guidance is terminated.

  If it is detected in step S7 that the vehicle has not arrived at the destination, the process returns to step S6 to continue route guidance.

  In this embodiment, the description has been made on the assumption that the walking mode is set. However, in the processing in step S2, when the walking mode is not set, the normal route search mode is set and the route search is performed. The route search for the shortest connection from the current position to the destination is performed in the means 15 (step S8).

  When a route search is performed in the process of step S8, route guidance is started in the process of step S9, and it is then detected whether or not the destination has been reached (step S10), and the destination is detected in the process of step S10. When it is detected that the route has arrived, the route guidance is terminated. When it is detected in step S10 that the vehicle has not arrived at the destination, the flow returns to step S9 to continue the route guidance.

  In the first embodiment, the walking input by the user based on the distance to the destination input by the user via the input unit 10 and the average moving speed in the previous walking mode stored in the storage unit 17. In the second embodiment, the navigation device 1 that searches for a route by inputting a desired walking distance instead of a desired walking time is described. This will be described using the flowchart of

  Note that steps S11 to S12 and steps S14 to S20 in the flowchart of FIG. 7 are the same as steps S1 to S2 and steps S4 to S10 in the flowchart of FIG. The process in step S13 in FIG. 2 is different from the process in step S3 in FIG.

  Therefore, step S13 will be described below, but the other processes are the same as those in FIG.

  In the process of step S <b> 13, the user inputs the number of steps and the step length via the input unit 10.

  As for the input of the number of steps, a numeric key is displayed on the display means 11 as shown in FIG. 8, and the user can input the desired number of steps by pressing the numeric key.

  When the number of steps is input, the step length is input next.

  FIG. 9 shows a screen for inputting a stride. Three icons for selecting a stride are displayed on the display means 11 shown in FIG. 9, and numerical values are assigned to 40 cm, 50 cm, and 60 cm, respectively. However, the present invention is not limited to this, and the number of icons can be set in advance by the user.

  Note that the numerical values of the icons displayed on the display means 11 may be displayed differently by the user inputting the sex and / or the age in advance.

  In the process of step S13, when the number of steps and the step length are input, the distance is calculated based on the input number of steps and the step length (for example, the number of steps is 10,000 steps × the step length is 60 cm = 6 km). The route search means 15 searches for a route arriving at the destination at the calculated distance.

  As described above, the navigation device of the present invention is used by the user when walking, and when the user wants to perform walking in consideration of health, he / she is busy and can take a lot of time. Even a non-person can find a vacant time and search for a route that can be further walked in the route desired by the user and provide it to the user. You can manage your health by using the device.
