When an operator, for example, a driver sets a parking lot of a department store, for example, as a destination, a route search process is performed, and a route from the current location to the parking lot is searched for. The map and the searched route are displayed, and the driver drives the vehicle according to the map or the searched route. However, when the vehicle arrives near the parking lot, it takes time to reach the parking lot due to traffic jam around the parking lot, or the parking lot of the department store is full and enters the parking lot It may take some time to access the parking lot.

Accordingly, the navigation device 14 of the present invention
In, an alternative facility is searched for as a peripheral facility in accordance with a preset peripheral facility search condition.

FIG. 3 is a main flowchart showing the operation of the navigation device according to the embodiment of the present invention.
FIG. 5 is a diagram illustrating a subroutine of a peripheral facility search process according to the embodiment of the present invention. FIG. 5 is a diagram illustrating a concept of the peripheral facility search process according to the embodiment of the present invention. FIG. 7 is a diagram illustrating an example of a search condition input screen, and FIG. 7 is a diagram illustrating an example of a peripheral facility information display screen according to the embodiment of the present invention. In the present embodiment, a case where a parking lot of a department store as a facility is set as a destination will be described. It is also assumed that each department store has a parking lot.

When the navigation device 14 (FIG. 2) is activated, the CPU 31 reads the current position detected by the GPS 21 and the direction of the vehicle detected by the gyro sensor 26, and obtains the map data acquiring means 91 (FIG. 2) of the CPU 31. 1) Reading and acquiring map data from the data recording unit 16. In the present embodiment, the map data acquisition unit 91 acquires map data from the data recording unit 16, but can also acquire map data via the communication unit 38.

The display processing means (not shown) of the CPU 31 performs display processing, sets a map screen on a display (not shown) of the display unit 35 based on the current position, the azimuth of the vehicle, and the map data. , The map of the present location, the direction of the own vehicle and the surrounding area is displayed. When the navigation device 14 is used as a route search device, when the driver operates the input unit 34 to input a destination, the destination setting processing means 92 of the CPU 31 performs a destination setting process, and Set the destination. Subsequently, the route search processing means 93 of the CPU 31 performs a route search process, and searches for a route from the current location to the destination based on the current location, the map data, and the destination. And
The display processing means displays a search route on the map screen.

Subsequently, when it is difficult to use the facilities at the destination, the driver sets whether the driver intends to change the destination. For example, when the destination is the parking lot of department store A, when it is found that it is difficult to use the parking lot of department store A, the surrounding facilities, for example, parking lots a, b around department store A, d, e, other department stores B to E around the department store A, parking lots a, c, d around the current location at that time, and other department stores E around the current location at that time. ,
Press (touch) a peripheral facility setting key displayed on the map screen. When the peripheral facility setting key is pressed, the display processing means sets a peripheral facility search condition input screen as shown in FIG. 6 on the display. Therefore, the driver operates the input unit 34 according to the guidance message on the peripheral facility search condition input screen to input the peripheral facility search conditions.

For example, on the peripheral facility search condition input screen shown in FIG. 6, a message m1 of "Do you want to display peripheral facility information during traffic congestion around the destination?" Do you want to display information about nearby facilities of the same genre or nearby parking lots? "
Title message m3 of "position of facility to display",
Title message m4 of "Timing to display",
"When the accumulated time in a state of 0 km / h at a position within a distance (100) m from the destination is (10) minutes or more"
And the message m6 of "Your average walking speed (5) km / h" are displayed.

When the message m1 indicates that it is difficult to use the parking lot of the department store A, the result of the search for the peripheral facility is referred to as peripheral facility information, that is, the peripheral facility information described later as peripheral facility information. A message asking whether to display the information on the information display screen.
On the other hand, if the driver wants to display the peripheral facility information, the driver presses the display key k1, and if not, the driver presses the non-display key k2. When it is difficult to use the parking lot of the department store A, the message m2 is at least one of the information on the surrounding department store (same genre facility information) and the information on the surrounding parking lot (parking lot information). Is displayed on the peripheral facility information display screen. In response to the message m2, the driver presses the display key k3 if he / she wants to display information on the surrounding department store. Presses the non-display key k4,
The driver presses the display key k5 when he / she wants to display the information on the surrounding parking lot, and presses the non-display key k6 when he / she does not want to display the information.

Then, the title message m3 is
This is a message for specifying the facility for displaying the peripheral facility information on the peripheral facility information display screen. When it is found that it is difficult to use the parking lot of the department store A in response to the title message m3, If the driver wishes to display the surrounding facility information about the other department store E or the parking lots a, c and d around the current location at that time, the driver presses the current location surrounding key k7 and the other department store B around the department store A. ~
When the driver desires to display the peripheral facility information about E or the parking lots a, b, d, and e, the driver presses the destination peripheral key k8.

The title message m4 and the message m5 are messages for setting the timing of displaying the peripheral facility information on the peripheral facility information display screen, and the destination is changed by the title message m4 and the message m5. The user is prompted to enter a destination change condition for determining whether or not the destination is changed. In the present embodiment, the destination change condition is a first determination condition indicating which point the vehicle changes the destination when the vehicle is traveling, and in what traveling state the vehicle is placed. A second determination condition indicating whether the destination is changed is determined. When the first and second determination conditions are satisfied, it is determined that the destination change condition has been satisfied.

In this embodiment, the first determination condition is satisfied when the vehicle enters a region at a predetermined distance from the parking lot of department store A, and the second determination condition is that the vehicle stops. It is established when the accumulated time of the state exceeds a threshold value. Then, the driver inputs the first determination condition to the frame f1 and the second determination condition to the frame f2 by pressing a numeric key or the like (not shown) of the input unit 34. In the example of the surrounding facility search condition input screen of FIG.
The first determination condition is satisfied when the vehicle enters the position within [m], and the second determination condition is satisfied when the accumulated time in the state of 0 [km / h] becomes 10 minutes or more. In this case, the engine and the navigation device 14 not shown
It is determined whether the first and second determination conditions are satisfied in a state where the power supply is turned on.

In this embodiment, it is determined whether or not the vehicle speed is 0 [km / h] and the second determination condition is satisfied based on the accumulated time in a state where the vehicle is stopped. However, the cumulative time during which the vehicle is traveling at a certain speed or less, the average speed of the vehicle within a certain time, the displacement of the current location per unit time (calculated by the distance between the coordinates of the current location or the integration of the vehicle speed) It is also possible to determine whether the second determination condition is satisfied based on the above. Further, it can be determined whether the second determination condition is satisfied based on traffic congestion information, parking space availability information, partner parking space availability information, and the like in the VICS information. Then, based on a difference between the arrival time calculated based on the distance between the current position and the destination and the expected arrival time calculated based on each of the traveling states, whether the second determination condition is satisfied? You can also determine whether.

The message m6 is used to input a condition for calculating how long it takes to walk from the peripheral facility to the department store A when using the peripheral facility when displaying the peripheral facility information. The driver inputs the average walking speed to the frame f3 by pressing the numeric keys or the like. In the example of the surrounding facility search condition input screen of FIG. 6, the driver sets the average walking speed to 5 [km / h].

After inputting and setting the peripheral facility search conditions in this way, when the driver presses a guide start key (not shown) on the peripheral facility search condition input screen, route guidance is started according to the search route. Therefore, the driver can drive the vehicle toward the parking lot of the department store A according to the guidance, the map, and the searched route.

Subsequently, the destination change condition satisfaction determination processing means 94 of the CPU 31 performs a destination change condition satisfaction determination process, and determines whether the set first and second determination conditions have been satisfied. When the first and second determination conditions are satisfied, it is determined that the destination change condition is satisfied. When at least one of the first and second determination conditions is not satisfied, the destination change condition is not satisfied. to decide.

Next, the peripheral facility search processing means 95 of the CPU 31 performs a peripheral facility search process when the destination change condition is satisfied and it is difficult to use the parking lot of the department store A. The current location detected by the GPS 21 is read, and at the same time, map data is read from the data recording unit 16 and a search is made by searching for peripheral facilities according to the peripheral facility search conditions set by the driver.

That is, the peripheral facility search processing means 95
When the display key k3 and the current location peripheral key k7 are pressed on the peripheral facility search condition input screen, another department store around the current location at that time (for example, within a range of 50 [m] from the current location) is searched, When the display key k5 and the current location surrounding key k7 are pressed, a parking lot around the current location at that time (for example, a range of a distance of 50 [m] from the current location) is searched. Further, when the display key k3 and the destination peripheral key k8 are pressed on the peripheral facility search condition input screen, the peripheral facility search processing means 95 sets the vicinity of the department store A (for example, 100 m from the department store A). range)
Is searched, and when the display key k5 and the destination surrounding key k8 are pressed, the area around the department store A (for example,
(A distance of 100 [m] from the department store A).

Subsequently, the peripheral facility information notification processing means 96 of the CPU 31 performs a peripheral facility information notification process, sets a peripheral facility information display screen as shown in FIG. 7, and displays the peripheral facility information display screen on the peripheral facility information display screen. The driver is notified by displaying the facility information. That is, when the display key k3 and the current location peripheral key k7 are pressed on the peripheral facility search condition input screen, the peripheral facility information notification processing means 96 displays and displays other department stores E around the current location at that time. When the key k5 and the current location surrounding key k7 are pressed, the parking lots a, c, and d around the current location at that time are displayed. When the display key k3 and the destination peripheral key k8 are pressed on the peripheral facility search condition input screen, the peripheral facility information notification processing means 96 displays and displays other department stores B to E around the department store A. When the key k5 and the destination surrounding key k8 are pressed, the parking lots a, b, d, and e around the department store A are displayed.

In the present embodiment, since all the searched peripheral facility information is not displayed on one peripheral facility information display screen, when the current location peripheral key k7 is pressed, As shown in FIG. 7, the peripheral facility information of the facilities around the current location is displayed, and when the destination peripheral key k8 is pressed, the peripheral facility information of the facilities around the department store A is displayed. . In addition, one peripheral facility information is displayed on the peripheral facility information display screen for each of the parking lot and the department store.

For example, on the peripheral facility information display screen shown in FIG. 7, the message m11 of "It seems that the vicinity of the destination is crowded" and the message "Current location is up to the destination (5
It is expected that it will take at least (30) minutes or more to arrive at the location 0) m. Message m12 of "Display facility information around current location", "Parking information around current location"
Title message m13, "(10) m from current location
At the location of (30) m to the destination at the location. If you park in this parking lot, you can arrive at the destination in about (8) minutes. "Message m14, title message of" Same genre facility information around current location " m15 and a message m16 of “facility located at (20) m from current location” are displayed.

The message m11 indicates that it is difficult to use the parking lot of the department store A, and the message m12 indicates the distance from the current location to the parking lot of the department store A in the frame f11. The time required to arrive at the parking lot of A is displayed in frame f12.

The title message m13 is
A message m14 displays the distance from the current position to the parking lot d in a frame f13, and the frame m13 indicates the distance from the parking lot d to the department store A. Displayed at f14, when the parking lot d is used, the time required to arrive at the department store A is displayed at frame f15. The title message m15 indicates that the surrounding facility information is information of another department store around the current location, and the message m16 indicates the distance between the current location and the department store E in a frame f16.

Note that k21 and k22 are scroll keys for sequentially displaying peripheral facility information one by one, k23 is an input key for switching between display of parking lot information and a map,
k24 is an input key for switching the display of the facility information and the map, and AR1 is an area conceptually representing the message m14.

When the driver sets a new destination by pressing a decision key (not shown) on the peripheral facility information display screen, the route search processing means 93 searches for a route based on the current location and the destination. Therefore, the driver
The vehicle can be driven to a new destination.

As described above, when the vehicle arrives at the vicinity of the destination, it takes time to reach the destination due to traffic congestion around the destination, or it takes time to use the facilities at the destination. When it is difficult to use the facility at the destination because of the above, the surrounding facility is searched and the peripheral facility information is displayed. Therefore, a new destination is set based on the peripheral facility information. be able to. Therefore, the operation for setting another facility as the destination can be simplified, and the time required to reach the destination can be shortened.

Even if the driver does not have information on other facilities, the driver can easily determine whether or not to change the destination based on the peripheral facility information.

Next, the flowchart of FIG. 3 will be described. Step S1 A destination is set. Step S2 Search for a route. Step S3: Enter surrounding facility search conditions. Step S4 Travel toward the destination. Step S5 A destination change condition satisfaction determination process is performed. Step S6: A peripheral facility search process is performed. Step S7 A new destination is set. Step S8: The vehicle travels toward the new destination, and the process ends.

Next, the flowchart of FIG. 4 will be described. Step S6-1: Search for surrounding facilities. Step S6-2: Display peripheral facility information and return.

In the above embodiment, the destination change condition satisfaction determination processing means 94 determines that the destination change condition is satisfied when the first and second determination conditions are satisfied. However, based on traffic information or the like by VICS, FM multiplexing, or the like, if the congestion level around the destination is equal to or higher than a certain value, or if the target parking lot is full for a certain period, It is also possible to determine that the surrounding area is congested and determine that the destination change condition is satisfied. In this case, it is determined that the destination change condition is satisfied regardless of whether the vehicle has entered a region at a predetermined distance from the destination.

It should be noted that the present invention is not limited to the above-described embodiment, but can be variously modified based on the gist of the present invention, and they are not excluded from the scope of the present invention.
