There is a device to do. Further, as disclosed in Japanese Unexamined Patent Publication No. 9-259282, “moving obstacle detection device and method”, an image of the front is taken using a sensor such as a TV camera mounted on a moving body, and the taken image is taken. There is a device that detects an obstacle by processing. In addition, VICS (Vehicl) provided by the Road Traffic Information System Center
There is a method of receiving a kind of obstacle information such as traffic congestion using a car navigation device using an e Information and Communication System and calculating an optimal route to a destination.

[0003]

Problems that can be considered as obstacles when a moving object passes on a road toward a destination include traffic accidents, width restrictions due to road construction, and heights. Regulation, weight regulation, noise regulation by displacement,

FIG. 7 shows a vehicle-mounted device 10 according to this embodiment.
3 is a flowchart showing a processing procedure in the information center 103. Hereinafter, the procedure will be described based on the flowchart of FIG.

In step 701, the person (the person who wants to obtain the route information) inputs / outputs the input / output unit 2 of the mobile communication vehicle-mounted apparatus 101.
03, the height, length, and the like of the moving object by using a sound such as a microphone or a touch display or a button.
When the entity information such as the width, the weight, and the displacement is input, the mobile in-vehicle device 101 stores the information in the memory 205. It should be noted that once these entity information is entered, it is stored in the entity history database 206, and the information is reused.

In step 702, the person determines whether there is a load and inputs the load to the vehicle-mounted device 101. In the case of the mobile in-vehicle device 101, if there is no load, step 7
Proceed to 06. If there is a load, the process proceeds to step 703, where it is determined whether or not the person is a specified load, and input to the vehicle-mounted device 101. The prescribed load is defined as a height and a length using a prescribed number (for example, a vehicle number may be a prescribed number in a case of a vehicle. Here, the vehicle number is assumed to be a prescribed number) as a key. The entity information such as width, weight, and displacement is defined in advance.

If it is a specified load, the process proceeds to step 704, and the person inputs a specified number for searching for entity information from the input / output unit 203 of the vehicle-mounted apparatus 101.
The input regulation number is stored in the memory 205. If the load is not the specified load, the process proceeds to step 705, and the person moves from information such as height, length, width, and weight that the load can be grasped to information that exceeds the entity information of the mobile. It is input from the input / output unit 203 of the on-body device 101. The input information is stored in the memory 205.

The method of the input operation in steps 701 to 705 is arbitrary. For example, a predetermined menu or a prompt message prompting an input may be displayed on the input / output unit 203 of the mobile communication in-vehicle apparatus 101, and the input of the person may be accepted. Subsequent inputs to the in-vehicle mobile communication device 101 are the same.

In step 706, the vehicle-mounted device 101 acquires the latitude, longitude, and altitude, which are the current position information of the moving object, from the GPS by the position information detecting unit 201 and stores it in the memory 205. Proceeding to step 707, when the person inputs the destination information of the moving object set according to the input condition of the route calculation function of the existing on-vehicle device from the input / output unit 203 of the on-vehicle device 101, the destination information becomes Stored in the memory 205.

Proceeding to step 708, the in-vehicle mobile device 1
01, the mobile entity information stored in the memory 205 (stored in step 701), and the specified number (step 70
4), load substance information (stored in step 705), current position information (stored in step 706), and destination information (stored in step 707). Information center 10 from 202
3 to the data transmission / reception unit 301. It should be noted that the prescribed number of the prescribed load and the load substance information are alternative information in which only one of them is stored in the memory 205 depending on which of the steps 704 and 705 is branched.

At the information center 103, step 710
Then, those data are received by the data transmission / reception unit 301. When the specified number of the specified load is transmitted, the specified entity database 307 is used based on the specified number.
(FIG. 4) is retrieved to obtain the entity information of the specified load.
Proceeding to step 711, based on the received mobile entity information and the non-specified load entity information input in step 705 or the specified entity information retrieved and obtained in step 710, the entity of the entire mobile object is determined. Calculated and stored in the memory 30
6 is stored. For example, as shown in FIG. 1, when focusing on the parameter “height”, the height of the moving body alone is, but in consideration of the height of the load, the actual height is
A numerical value obtained by adding the height to the loading platform and the height of the load is calculated as the height of the entity of the entire moving body. Based on the same concept, the values of parameters such as width, length, weight, and displacement are calculated as the whole of the moving object.

Next, the process proceeds to step 712, where the destination route calculation unit 303 calculates a route from the current position to the destination based on the current position information and the destination information of the moving object with reference to the specified map data berth 308. Then, the data is stored in the memory 306. Here, it is assumed that a route that captures the moving object as a point is calculated, and a plurality of routes as candidates are obtained.

In step 713, the traversable area correction route calculating section 304 determines whether the route obtained in step 712 corresponds to the entity information of the moving object (the information obtained in step 711, taking into account the load, etc.). Considering the information representing the entity of the entire moving body), the availability of the route is calculated. For example, since the width, length, height, weight, and displacement of the entire mobile entity are known from the mobile entity information, the reference map database 308 is referred to.
In the route obtained in the step 712, there is no portion of the road width that cannot be passed by the width of the mobile entity, there is no corner that cannot be bent by the length of the mobile entity, or the height of the mobile object is Investigate whether there are any parts that cannot pass, whether there are bridges that cannot pass due to weight restrictions, and whether there are any areas that cannot pass due to noise restrictions due to displacement. The same applies to other entity information other than those exemplified here.
The specified map database 308 includes, in addition to the road position information, road widths, road lengths, right / left turn angles, height restrictions, weight restrictions such as bridges, irregular road surfaces, sign laws and regulations, sign time regulations, Since the parking lot / space regulations and the like are stored, it is possible to determine whether or not the route obtained in step 712 is passable or not by comparing the information with the mobile entity information. The obtained information is stored in the memory 306.

Further, in step 713, the traversable area correction database 309 compares the trajectory obtained in step 712 with the traversable area correction database 309.
Based on the information (temporary change information with respect to the specified map information) stored in the information processing device, a process for determining whether or not the vehicle can pass through the route is also performed. Passable area correction database 3
09 stores restriction information due to temporary traffic regulation due to an accident, construction, traffic congestion, or the like.
Even in the route obtained in step 2, there is a case where it is impossible to pass.
Also, as shown in the lower part of FIG. 1, when the normal road width is narrowed due to road construction or the like, the fact is stored in the traversable area correction database 309, and when the road is not allowed due to the width of the mobile entity , The route is NG. For all of the routes determined in step 712, it is determined whether the route is passable (OK) or not (NG), and the result is stored in the memory 3.
06.

Next, the routine proceeds to step 714, where the memory 306
The route search result from the current position to the destination stored at the present time is stored in the data transmitting / receiving unit 30 of the information center 103.
1 to the vehicle-mounted device 101.

If the distance from the current location to the destination is long and the traveling process takes a significant amount of time, a change may occur in the traversable area during the movement of the moving body, and the originally calculated route calculation result may change. Comes out. In this case, steps 712 to 714 are executed at a predetermined timing according to the moving speed of the moving body, the distance to the destination, and the elapsed time, and the route from the current position of the moving body to the destination is calculated again. Then, the updated route information around the moving object is transmitted from the data transmitting / receiving unit 301 of the information center 103 to the vehicle-mounted device 1.
Send to 01. This allows you to reach your destination
At appropriate intervals, route information around the moving object is sequentially transmitted.

In the mobile in-vehicle apparatus 101, step 70
At 9, the data transmission / reception unit 202 of the in-vehicle mobile device 101 receives the route calculation result, and displays the received route information in an appropriate method. If the distance to the destination is long, the latest route information around the moving body is transmitted from the information center 103 at a predetermined timing according to the moving speed of the moving body, the distance to the destination, and the elapsed time. The in-vehicle mobile device 101 may receive and display the information. Also, on the mobile unit in-vehicle device 101 side, the processing from step 706 is performed at a predetermined timing according to the moving speed of the mobile unit, the distance to the destination, and the elapsed time (however, the input of the destination in step 707 is unnecessary). The latest progress around the moving object may be repeatedly and sequentially displayed.

FIG. 8 is a diagram showing an example of the route calculation result (displayed in step 709 in FIG. 7) displayed on the mobile in-vehicle apparatus according to the present embodiment. As shown in FIG.
In the route search result display according to the present embodiment, a route that avoids obstacles in traveling from the current location to the destination, that is, a route that is OK (“route 3” and “route 4” in FIG. 8)
Is displayed, and the routes that cannot be passed, that is, the routes that have become NG (“Route 1” and “Route 2” in FIG. 8) are also displayed. Also, the displayed route is input / output unit 203
To display the reason that the route is NG and the location of impassable traffic. Reference numeral 801 in FIG. 8 shows a case where the route 1 or the route 2 which is NG is selected, and the impassable portions of those routes and the reason are displayed. FIG.
Reference numeral 802 denotes a route screen displayed when the route 3 or route 4 that is OK is selected.

FIG. 9 shows another example of the route calculation result displayed on the vehicle-mounted apparatus according to the present embodiment (step 709 in FIG. 7).
). In this example, because the distance to the destination is long, the route calculated and displayed at a certain point in time,
This is an example in which the route calculated and displayed after a predetermined time is different.

For example, as shown at 901 in FIG. 9, at time 10:05, there is no obstacle at a point on the way to the destination, so that the shortest distance route is displayed. At 10:20 when the moving object has traveled along the route, road obstacle information has occurred on the route, and a route calculation result with a detour set is displayed. In this way, even when a failure occurs on the route of the moving object, the route is recalculated and displayed at a predetermined timing, and accordingly, according to the moving speed of the moving object and the distance to the destination, The latest route information around the moving object can be obtained until the user arrives at the destination.

In the above embodiment, functions of the information center such as a function of acquiring map information and information from VICS may be provided in the vehicle-mounted apparatus.
