[0046]
FIG. 5 is a diagram illustrating an internal configuration example of the extension module 11.
[0047]
A GPS antenna 121 provided in the rotation unit 23 of the extension module 11 receives a GPS signal transmitted from a GPS satellite (not shown).
[0048]
The GPS signal processing unit 113 provided inside the main body 22 determines the latitude, longitude, altitude, time, speed, and heading direction of the current location where the PDA 1 is used from the GPS signal received by the GPS antenna 121. GPS reception data is calculated and recorded (stored) in the storage unit 102. The GPS signal processing unit 113 also adjusts the internal clock of the clock 112 to an accurate time based on the time data in the calculated GPS reception data. The GPS signal processing unit 113 further causes the storage unit 102 to record the calculated GPS reception data (position data and time data) as past trajectory data.
[0049]
This past trajectory data is data used when the GPS antenna 121 cannot receive a GPS signal due to an obstacle or the like.
[0050]
The clock 112 is driven by the power supply voltage supplied from the PDA 1 via the interface (I / F) 101 and stores the internal clock adjusted by the GPS signal processing unit 113. The clock 112 is also driven by the power supply voltage supplied from the internal battery 111 when the expansion module 1 is not attached to the PDA 1 (that is, when there is no power supply), and is adjusted by the GPS signal processing unit 113. To maintain.
[0051]
The storage unit 102 provided in the mounting unit 21 stores communication data for the PDA 1 and the extension module 11 to communicate with each other, such as driver software for driving the GPS reception function and interface protocol data. The storage unit 102 also records GPS reception data and past trajectory data supplied from the GPS signal processing unit 113.
[0052]
Further, map data for the PDA 1 to realize a portable navigation system is divided into predetermined blocks (small areas) and recorded in the storage unit 102. The map data is data around a region where the PDA 1 is used (for example, Kanto region).
[0053]
Here, a process for causing the expansion module 11 to record map data will be described. For example, the map data is recorded in the storage unit 102 of the extension module 11 by the following method.
[0054]
(1) The expansion module 11 is installed in the memory card slot of the personal computer, and the CD-ROM (Compact Disc-Read Only Memory) in which the map data is recorded is installed in the personal computer drive. Copy (record) the map data to the module 11.
[0055]
(2) The expansion module 11 is inserted into a memory card slot of a personal computer or a mobile phone, and map data is downloaded from a predetermined site via the Internet and recorded in the expansion module 11.
[0056]
(3) The expansion module 11 is mounted in the memory card slot of the PDA 1, the PDA 1 and the mobile phone are connected, connected to the Internet via the mobile phone, map data is downloaded from a predetermined site, and recorded in the expansion module 11. .
[0057]
(4) The expansion module 11 is mounted in the memory card slot of the PDA 1, the PDA 1 is connected to a terminal installed in the store, map data is downloaded from a predetermined server via the terminal, and is recorded in the expansion module 11.
[0058]
Thus, when the expansion module 11 is mounted on the PDA 1, map data is recorded in advance in the expansion module 11 so that the PDA 1 functions as a navigation system.
[0059]
The GPS reception data, past trajectory data, and time data of the clock 112 stored in the storage unit 102 are sent to the PDA 1 via the interface 101.
[0060]
Next, the virtual route setting process executed by the CPU 51 of the PDA 1 will be described with reference to the flowchart of FIG. In starting this process, the navigation program has already been started in the CPU 51 of the PDA 1, and the user operates the touch pad 2a, the key 3, the jog dial 4 or the like, and starts the process from a predetermined point (for example, the current location). It is assumed that the route is being searched by instructing the route of the ground.
[0061]
In step S1, when the user operates the touch pad 2a, the key 3, or the jog dial 4 to instruct the setting of a virtual route from a predetermined point to the destination (a route that does not actually pass but is to be tried) The CPU 51 determines the setting of the virtual route.
[0062]
In step S <b> 2, the CPU 51 receives a map corresponding to the road of the set virtual route from the extension module 11 via the module interface 55, that is, a map for one block in a region where a map image is displayed on the display unit 2. Read data.
[0063]
In step S <b> 3, the CPU 51 causes the EDO DRAM 54 to draw a map image corresponding to the map data read in step S <b> 2, reads the image from the EDO DRAM 54, and displays it on the display unit 2.
[0064]
In step S4, the CPU 51 determines whether all blocks in the range corresponding to the route road set in step S1 have been drawn on the display unit 2, and determines that there are still undrawn blocks. If so, the process returns to step S2, and the subsequent processing described above is repeatedly executed.
[0065]
In this way, for example, as shown in FIG. 7, the map image is displayed on the display unit 2. In the case of the example in FIG. 7, maps near Gotanda Station and Shinagawa Station are displayed.
[0066]
If it is determined in step S4 that there is no undrawn block, that is, all blocks in the range corresponding to the road of the virtual route set in the process of step S1 are drawn on the display unit 2, the process proceeds to step S5. Proceeding, the CPU 51 highlights the set virtual route.
[0067]
Thereby, for example, as shown in FIG. 8, the virtual route set by the user is highlighted and the current location and the destination are displayed.
[0068]
On the screen shown in FIG. 8, the user uses the touch pad 2a, the key 3, or the jog dial 4 to perform an operation for setting the moving means. The CPU 51 receives an operation input by the user and displays a list box 151 for selecting a moving means as shown in FIG. 9, for example. In this list box 151, “train”, “car”, “bicycle”, and “walk” moving means are preset, and the user sets (selects) a preferred moving means from among them. can do. It is of course possible to change the moving means once set.
[0069]
In step S6, the CPU 51 determines whether or not the moving means has been set, that is, whether or not the predetermined moving means has been selected by the user from the list box 151 shown in FIG. The determination process is repeatedly executed until it is done.
[0070]
If it is determined in step S6 that the moving means is set, the process proceeds to step S7, and the CPU 51 displays a mark corresponding to the set moving means.
[0071]
As a result, for example, as shown in FIG. 10, a mark 161 indicating the moving means set by the user is displayed, and the user can easily know the moving means set in the virtual route.
[0072]
Next, route display processing executed by the CPU 51 of the PDA 1 will be described with reference to the flowcharts of FIGS. 11 to 13.
[0073]
In step S21, the CPU 51 determines whether or not GPS data has been received, that is, whether or not new GPS reception data has been calculated by monitoring the GPS signal processing unit 113 of the extension module 11 via the module interface 55. Then, the above-described processing is repeatedly executed until it is determined that the GPS signal processing unit 113 has calculated new GPS reception data.
[0074]
If it is determined in step S21 that the GPS signal processing unit 113 has calculated new GPS reception data, the process proceeds to step S22, and the CPU 51 receives GPS reception data such as latitude information and longitude information calculated by the GPS signal processing unit 113. Is stored in the Flash ROM 53. In step S23, the CPU 51, based on the latitude information and longitude information acquired in the process of step S22, for example, as shown in FIG. 14, the current position where the PDA 1 is used, that is, the user's actual A mark 171 indicating the current position is displayed.
[0075]
In step S24, the CPU 51 determines whether or not the moving means set for the virtual route is “walk” or “bicycle”, and the moving means set for the virtual route is “walk” or “bicycle”. If it is determined, the process proceeds to step S25, and the movement distance is calculated according to the elapsed time from the start of the predetermined point (departure start point).
[0076]
For example, when “walking” is set as the moving means of the virtual route, the moving speed set by setting the moving means is 80 m / min, and the elapsed time from the start of departure is 15 minutes, The movement distance is calculated according to the following equation (1).
Movement distance = 80 (m / min) × 15 (min) = 1200 m (1)
[0077]
Also, for example, when “bicycle” is set as the moving means of the virtual route, the moving speed set by the setting of the moving means is 250 m / min, and the elapsed time from the start of departure is 10 minutes Then, the movement distance is calculated according to the following equation (2).
Movement distance = 250 (m / min) × 10 (min) = 2500 m (2)
[0078]
In step S26, the CPU 51 displays a mark 172 indicating the current position on the virtual route based on the movement distance calculated in the process of step S25, for example, as shown in FIG. Proceed to
[0079]
If it is determined in step S24 that the moving means set in the virtual route is not “walking” or “bicycle”, the process proceeds to step S27, and the CPU 51 further sets the moving means set in the virtual route to “automobile”. If it is determined whether or not the moving means set in the virtual route is “automobile”, the process proceeds to step S28, and data on the congestion condition of the road on the virtual route is acquired.
[0080]
For example, data relating to road congestion may be distributed every predetermined time from a predetermined traffic management server or the like via a network such as the Internet or a satellite. It doesn't matter.
[0081]
In step S29, the CPU 51 determines whether or not the road is congested from the data related to the congestion condition of the road on the virtual route acquired in the process of step S28, and if it is determined that the road is congested, Proceeding to step S30, the traveling speed of the vehicle actually traveling on the virtual route is acquired.
[0082]
The traveling speed of the vehicle actually traveling on the virtual route may be included in the data related to the congestion of the road, or may be separately distributed from the traffic management server described above. Good.
[0083]
In step S31, the CPU 51 calculates the travel distance according to the elapsed time from the start of departure at the predetermined point and the traveling speed of the vehicle actually traveling on the virtual route acquired in the process of step S30. To do.
[0084]
For example, when the traveling speed of an automobile actually traveling on the virtual route is 10 km / h and the elapsed time from the start of departure is 15 minutes, the moving distance is calculated according to the following equation (3).
Travel distance = 10 (km / h) × 0.25 (time) = 2.5 km (3)
[0085]
If it is determined in step S29 that the road is not congested from the data related to the road congestion on the virtual route acquired in step S28, the process proceeds to step S32, and the CPU 51 acquires in step S22. The actual movement distance moved from the departure start point is calculated from the received GPS reception data, and is determined as the movement distance on the virtual route.
[0086]
In step S33, the CPU 51 displays a mark 172 (FIG. 14) indicating the current position on the virtual route based on the movement distance calculated in the process of step S31 or the movement distance determined in the process of step S32. Then, the process proceeds to step S40.
[0087]
If it is determined in step S27 that the moving means set to the virtual route is not “automobile”, the process proceeds to step S34, and the CPU 51 determines that the moving means set to the virtual route is “train”. In step S35, data relating to the operation status of the train on the virtual route is acquired.
[0088]
The data related to the train operation status may be distributed every predetermined time from a railway management server or the like via a network such as the Internet or a satellite, and the acquisition method is not particularly limited. .
[0089]
In step S36, the CPU 51 determines whether or not the train operation status is disturbed from the data related to the train operation status on the virtual route acquired in the process of step S35, and the train operation status is disturbed. If it is determined that the current position on the virtual route is calculated in accordance with the elapsed time from the start of departure of the predetermined point, after subtracting the delay time due to the disturbance of the operation status.
[0090]
For example, when the delay time due to disturbance of the train operation status is 15 minutes and the elapsed time from the start of departure is 30 minutes, the travel time is calculated according to the following equation (4).
Travel time = 30 (minutes) -15 (minutes) = 15 minutes (4)
[0091]
Then, the current position is determined based on the travel time calculated by the above equation (4). That is, since the traveling speed of the train is set to be almost constant for each route, if the travel time is known, the travel distance from the predetermined station can be obtained.
[0092]
If it is determined in step S36 that there is no disturbance in the train operation status, the process proceeds to step S38, and the CPU 51 calculates the current position on the virtual route according to the elapsed time from the start of departure.
[0093]
In step S39, the CPU 51 determines the mark 172 (FIG. 14) indicating the current position on the virtual route based on the current position calculated in the process of step S37 or the current position calculated in the process of step S38. Is displayed, and then the process proceeds to step S40.
[0094]
In step S40, the CPU 51 determines whether or not to end the navigation, that is, whether or not the user has operated the touch pad 2a, the key 3, or the jog dial 4 to input the navigation, or sets the destination. If it is determined whether or not the navigation has arrived and it is determined that the navigation has not yet ended, the process returns to step S21 and the above-described processing is repeatedly executed.
[0095]
If it is determined in step S40 that the navigation is to be terminated, the process is terminated.
[0096]
