Description

Location, route, route program and record that can be read

Surgical field

0001 This document relates to a route, route method and route record that can be read by a route program that searches for a route to a specific point where an accident easily occurs or a destination that avoids a specific route. However, it is not limited to the recording media that can be read by the above-mentioned route, route method, and route program. Since 2020, in the route search that is made in the navigation system, the route from the departure point to the destination point is evaluated using the information of each point that is already stored. Then, the most evaluated route among these routes is selected as the optimal route, and the selected optimal route is displayed as the traveling route (for example,

. ).

[0003] In addition, like the Liteda on board an airplane, the Dryda is known to record the situation of both running vehicles. This driver is, for example, a front camera that captures the front of the vehicle, a rear camera that captures the rear, and a front camera.

The 004 driver, which is equipped with the function to write the image in the area of the image memory in synchronization with the reference signal, adds the vehicle information to the image information and records it regularly. Then, the above information is sent and stored by inputting a signal that exceeds the fixed value of the impact sensor. For example, when you encounter an accident such as an address escape, you can specify the address escape (for example, 2 below).

Akira's task to solve

However, in the above-mentioned patent, the shortest route from the starting point to the destination point was evaluated and the shortest route was selected as the optimum route. Some of the routes selected for this route may include accident prone points or points. For this reason, if you move to the destination based on the route selected as the optimal route for conventional navigation, you will encounter an accident and the problem of high attention will be given as an example.

0007 In addition, for example, if the Z is near the starting point or the destination point, it may have some knowledge of the accident-prone point or point. In this case, The may avoid an accident-prone point or a route to the destination without relying on the route selected for navigation.

However, in the case of land, there is no choice but to rely on the route selected by the navigation system, and if an accident is encountered as described above, a high degree of attention can be given as an example.

[0000] In addition, in the above-mentioned Patent 2 technique, the image of the side of the accident and the vehicle information are added to the driver and recorded. Therefore, the accident occurrence point can be confirmed after the fact by analyzing the report of the driver.

However, if you rely only on the memory of The, you may forget the confirmed accident location in the subsequent driving, and you will eventually have to rely on the route selected for the navigation. . For this reason, the information about the accident location recorded in the driver cannot be effectively used, and as a result, the function of the driver cannot be effectively utilized.

001 Also, it is conceivable that the operation of the accident recorded in the driver will be put on the map data by the operation of the theatre, but the annoying work of the annoyance at the theatre is the annoying. The question is given as an example. In addition, this dry As an example, it is not possible to record an image of a high-altitude point or a place where an accident is likely to occur even though no accident has actually occurred.

Good for carrying out the invention

[0118] With reference to the appendices below, a detailed description will be given of the route, the route method, the route program, and the proper implementation of the recording medium readable by the computer.

0019 (Out of)

(Positional function)

The functional configuration of the route according to this embodiment will be explained using. [Fig. 6] is a diagram showing an example of the functional configuration of the route device according to the present embodiment. In, the route is composed of input, acquisition 2, and route 3.

0020 accepts the force of the target point of the moving body. This is done by operating the operation unit at the target location. For example, the user may input the name or address of the destination point by operating the operation unit, or the force of the destination point may be generated by putting on the map displayed on the display. Yeah. Furthermore, the input may be configured to accept the time required to reach the destination. The required time is the time required for the moving body from the starting point to the destination point.

002 2 acquires a specific point or specific point where an accident is likely to occur.

The second step is to acquire a specific point or a specific point at which an accident is likely to occur, from the recording body that records information about the line state of the moving body. The specific point or point at which the accident is likely to occur is a point or point at which the moving body may be in a dangerous traveling state. Furthermore, the specific location or location where an accident is likely to occur is the location or location where the moving body is in a dangerous running state. In addition, in Acquisition 2, the road data represented by the link of a specific shape is selected from the road network data as the specific data. It is also possible to obtain it.

002 3 searches for a specific point acquired in Acquisition 2 or a route to a destination point that has been manpowered by input avoiding a specific point. In addition, if the route to the specific point or the destination that avoids the specific route is not searched, the route 3 searches for the route where the number of the specific points is the predetermined number or less or the minimum.

In addition, Route 3 is configured to search for a route that has a specified number of points or less or a minimum number if the route to the specified point or the destination avoiding the specified point is not found. Moyo. Furthermore, route 3 may be configured to search for the route with the shortest specific route.

002 In addition, weight information regarding the accident can be added to the specific point or the specific point, and the route 3 can also be configured to search for the route to the destination point based on the weight information. . In addition, when the input of the time required to reach the destination is received, the route 3 can be configured to search the route to the destination based on the input required time.

002 (place)

First, the route arrangement according to the present embodiment will be described in order. 2 is a chart showing the order of the route arrangements in this embodiment. In the chart of step 2, first, the route is judged by inputting the force of the destination point (step s2). For example, by operating the operation unit to enter the name or address of the destination, or by operating the operation unit on the map displayed in the sign display and putting the destination point. The power of. In addition, the input can also accept the time required to reach the destination. The required time is the time required for the moving body to reach the destination point.

002 In step s2, wait for the power of the destination to be received, and if it is received (step s2 es), acquire the specific point or specific point where the accident is likely to occur. Yes (step 2 2). The specific point or specific point where the accident is likely to occur is obtained from the recording body in which the information regarding the row state of the moving body is recorded. As described above, the specific point or point at which the accident is likely to occur is a point or point at which the moving body may be in a dangerous traveling state. Furthermore, the point or point at which the moving body is in a dangerous driving state is also a specific point or point at which an accident is likely to occur. In addition, in Acquisition 2, from the road network data, the road data represented by the specific shape of the link can be acquired as the specific data.

Then, the route 3 searches for a route to the specific point acquired by the acquisition 2 or the destination point avoiding the specific point (step 23). If a route to a specific point or a destination that avoids a specific point is not found, a search will be performed based on a predetermined number of cases. An example of such a case is the case where the number of specific points is less than or equal to a certain number or the route with the smallest number is searched.

[0303] Other examples of the predetermined number of cases include a case where the number of specified points is equal to or smaller than a predetermined number, or a path where the number of specified points is the shortest is searched for.

003 It is possible to add weight information on accidents to specific points or points. If information is added, the route is based on this information.

3 can also be configured to search for a route to the destination. In addition, if the power of the time required to reach the destination is accepted by human power,

3 searches the route to the destination based on the input required time. According to the implementation route, the route is searched by avoiding a specific point or a specific route where the moving body may have been in a dangerous driving state in the past, or was in a dangerous driving state. be able to. In addition, if the route to all the fixed points or the destination avoiding the specified points is not searched, it is possible to perform the search based on the predetermined conditions and obtain the results according to the predetermined conditions.

As described above, according to this embodiment, it is possible to provide a safe and practical route, route method, route program, and computer-readable recording medium. 003 will be explained below. In the implementation, for example, the case where the device is installed by a navigation device mounted on a moving body such as a vehicle (including a motorcycle and a motorcycle) will be described.

003 (Navigation Door)

We will use 3 to explain how to create a navigation device for this project. Figure 3 is a schematic diagram showing an example of how to create a navigation device for this implementation.

In 003 3, the navigation 3 has CP (Ce a Pocess) 3 and RO (ead O eo) 3 2 and (a do ccess eo) 3 3, a magnetic disk dry 3 4 and a magnetic disk 3 5 , Disc Dry 36, Disc 37, Audio 1 (Interface) 38, Eq 39, Speaker 3, Input Device 3, Video 32, Camera 3 3, Display 3 4, f 3 5, GPS (Goba Pos o S se) 3 6 and various sensors 3 7. Further, 3 to 37 are connected by a space 32.

003 First, CP 3 controls the body of Navigation 3. 32 records programs such as programs, communication programs, database programs, and program programs. R 33 is also used as a working CP 3. 3 2 or R 3 3 is secured with a medium that enables rewriting of the information acquired from the navigation 3 section.

003 Disc Dry 34 controls the uptake of only data to Disc 35 according to the control of CP 3. The disk 35 records the data written by the magnetic disk drive 34. As the disk 35, for example, (disk disk) or (key disk) can be used.

Further, the disk drive 36 controls the loading of only the data to the disk 37 according to the control of the CP 3. The disc 37 is an existing recording medium whose data is produced according to the disc dry 36 control. Di The disk 37 can also use a writable recording medium. The current recording medium may be disk 37, O, or media.

On the body such as 004 disk 3 5 disk 3 7 etc., each control program and each type of information are recorded in a readable state. The information may include, for example, map information used for routes and guidance. Represents a map of a body, a building, a river, a ground surface, etc. recorded on the body

, Which shows the shape of the road, and is drawn in 2 or 3 dimensions on the surface of the display 34 described later.

004 shows the map information read from the recording medium by the magnetic disk drive 3 4 disk drive 3 6 and the position of the vehicle acquired by the GPS 3 6 which will be described later. Will be displayed on display 34.

In addition, the magnetic disk 3 5 disk 37, etc.

It is also possible to record the location information of the vehicle inside and outside the vehicle obtained in 3 3 and detected by the GPS unit 36, which will be described later, and the values from various sensors 37, which will be described later. These are recorded by the drive function of the navigation 3 which will be described later, and are used for determining the location of traffic accidents and the number of traffic accidents.

I tried to record on a body such as 7, but it is not limited to this.

The contents, etc. may be recorded in the third part of the navigation. In that case, the navigation 3 obtains the map content etc. through the communication 35, for example. The obtained information is stored in R 33 or the like. Further, the voice 38 is connected to the voice input device 39 and the voice output device 3. The voice that was sent to iku 3 9 is replaced within voice 3 8. Also, the voices are output to the speakers. The voice that is input may be, for example, content recorded on the body such as a magnetic disk 3 5 disk 3 7 or the like. There are voices. The audio input from the device 39 can be recorded on the disk 35 or the disk 37 as audio data.

Further, the input device 3 is provided with a number for inputting a character, a numerical value, various indications, a keyboard, a mouse, a touch panel, or the like. Furthermore, the input device 3 can output other data by connecting to other information processing such as a digital camera (below, simply with the device).

The video 32 is also connected to the display 34. 32 is, for example, a graphic such as R (deo R), which temporarily records an immediate image information when controlling the display 3 4 bodies, and a graphic. It is composed of control C, etc. that controls the display 34 based on the image data that is output.

The 004 333 takes an image outside the vehicle and outputs it as image data. The image obtained in 3 3 can be recorded on the disc 3 5 or the disc 3 7 as image data. On the display 34, data such as an icon, a font, a font, a window, or a character image is displayed. The display 34 may be, for example, a C display or a plasma display. 004 Also, the display at the current position of the navigation 3 is displayed on the display 34. Display 34 is mainly used to display the current road, and when stopped, displays information such as TVs. , Space for displaying the current time is secured. Note that a separate display may be provided to indicate the current time at all times.

In addition, f35 is connected to the network via wireless and

3 and CP 3 interface. The f 3 5 is further connected to the Internet or other communication network via radio and functions as this communication network CP 3 interface.

The 050 network includes WA and public mobile phone networks. Physically, f is, for example, China CS (e ce aoad Coca o S se) It consists of a vehicle, a wireless navigation device, and other navigation devices, and obtains road traffic information such as traffic regulations called by the CS Center. Note that CS is a registration mark. In addition, the information obtained through the 35 includes, for example, public data on the Internet, information on various waves such as radio transmission, and voice information.

005 In addition, the GPS unit 36 uses the GPS stars and various sensors (eg, angular velocity sensor, acceleration sensor, number of tires, etc.) to determine the vehicle's location (the location of the navigation 3). ) Is calculated. This is the information that indicates the current position, for example, the point that identifies the point above the longitude and latitude.

The various sensors 37 are sensors, acceleration sensors, sensors, etc., which determine the current position by the GPS 36, measure the speed and position weight, and determine whether to operate the dry function. Used for etc. Further, the various sensors 37 may be used to detect an operation such as a vehicle's handicap. In addition, it can also be used as data to be recorded by various drivers for various sensors.

005 Here, I will simply explain the driver function of Navigation 3. The driver will record to the destination and record the information about the running condition of the vehicle. Physically, for example, the driver's position of the vehicle obtained by the driver, the voice obtained by the iku 3 9 3 3 and the GPS dot 3 6 various sensors 37, etc. 5 Record on disc 3 7.

By constantly recording the driving conditions using the dry drive function, the points or points at which the vehicle could be in a dangerous driving state or the points or points at which the vehicle actually became a dangerous driving state can be recorded. be able to. In addition, if the vehicle is involved in an accident, or if an accident occurs around the vehicle, it is possible to obtain materials for clarifying the facts. The information to be recorded using the drive function may have a structure in which the storage capacity of the recording medium is accumulated as much as possible, and the recording for a predetermined time is left. It can be configured as well.

005 The navigation 3 also has the functions of live streaming of C, C, etc., video transmission, and internet connection. Like these driver functions, it is performed using the navigation 3 source, so if you try to perform other functions while the driver function is running, the driver will There may be a shortage of resources.

005 Therefore, the Navigation 3 normally drives the door source dry.

It may be configured so that the driver function is activated when the accident possibility is equal to or higher than a predetermined value, while it is used for the functions other than the function. This makes it possible to effectively utilize the limited source of power and record information on both line conditions at the time of the accident.

Here, the possibility of an accident that activates the driver function is reported using vehicle movements and location reports of both vehicles. Both types of movement are, for example, the degree and degree of change of the vehicle, the direction of travel, and sudden movement of the vehicle. The navigation 3 can obtain these information by acquiring outputs from various sensors 37 and GPS 36.

The action of the possibility of occurrence is an action that increases the steepness while driving, for example, when the vehicle is out of the right turn limit. In addition, when the vehicle is in the right turn and the left turn window is blinking, or when the traffic light shows a yellow-red signal and the speed is too high, It is possible to determine that the probability of an accident is high due to the combination of the movements of the vehicles in which the vehicle is located. In addition, consider the weather and calculate the probability of an accident. For example, the probability of an accident may differ depending on the amount of water and the wind speed over time. For example, if the values of various sensors such as the vibration sensor G sensor are stipulated values, or if it approximates to a constant tan indicating an abnormality, or if the contact sensor operates, it is judged that the accident probability is high. Moyo.

Navigation 3 scores these eyes, for example, and uses the total number of applicable eyes as the probability of an accident. For example, The higher the degree of danger, the higher the number of accidents, such as 2 points.

006 0 You may also judge the probability of an accident by using the location of the vehicle or its information. For example, if there is a point where an accident is likely to occur, such as a point where intersections such as intersections and three-way intersections intersect, a point with a high curvature, bad visibility, or a corner with a building in the direction of turn, etc. Therefore, it is highly probable that an accident will occur.

006 In addition, if you can obtain the accident information about the accidents that occurred in the past at each point, you can calculate the accident occurrence probability by referring to the accident information. For example, if the situation of an accident that occurred in the past coincides with the time of day, the degree of road, etc., it is judged that the probability of an accident is high. Navigation 3 comprehensively judges the above factors and activates the drive function if the accident probability exceeds a specified value.

Note that the input, which is the effective configuration of the route to be implemented, is input by the input device 3, the acquisition 2 is by CP 3 or 3 2 and R 33, and the route 3 is by CP 3. Realize that ability. 006 (for navigation 3)

First, we will explain in order of Navigation 3 in this implementation. 4 is a chart showing the order of navigation devices in this implementation. In the following, the same symbols will be used in the explanations where they overlap with those already explained.

In the chart of 004, the navigation 3 first determines whether or not the force of the destination has been received via the input chair 3 (step S4). The operation may be performed by inputting the name or address of the destination point by operating the input device 3 of the target point, such as the keyboard, keyboard, mouse, or touch panel.

006 In Step 4, waiting for the power of the destination to be received, and if the power is received (Step S4 es), the CP 3 is (Step 4 2). The information about the row condition of the vehicle, which is recorded by the dry drive function at a fixed point or a specific point, is obtained from the magnetic disk 3 5 disk 3 7. In addition, for example, through communication 35, the road data represented by a specific shape link may be acquired from the road network data via the network. Further, the information acquired from the road network data may be stored in the body such as R 33.

006 Here, a specific point or specific point where an accident is likely to occur is, for example, a dry place.

The point or point at which the vehicle recorded using the function is in a dangerous driving state, or the point or point at which the vehicle is actually in a dangerous driving state. Physically, it is a point or point at which the accident occurrence probability exceeds a prescribed value, and as described above, the accident occurrence probability is issued by using the vehicle movement and the location information of both. More physically, a specific point or specific point where an accident is likely to occur (below, a specific point or specific point with the possibility of an accident) is entered in the right turn if it exceeds the right turn limit. Nevertheless, if the wink is blinking, or if the traffic light shows a yellow-red traffic light, but the speed is higher than the limit, the point where the operation is performed to increase the ruggedness, It is

At 006, CP 3 searches for a destination up to the destination manually input (step 43). Search for the specific point obtained in step 42 or the avoidance point that avoids the specific point up to the target point.

Then, the CP 3 determines whether or not the avoidance route has been searched (step S44). 069 In step 44, if the avoidance route has been searched (step 4 4es), the display 3 4 is searched. Display the result (step 45) and finish the series of operations. If there are multiple results, you can operate the input device 3 to display the results on the display 34 according to the display mode you set. For example, it is possible to display 5 roads on the display 3 4 in order from the one with the shortest distance to the destination. In addition, for example, payments are calculated when passing through a road such as an expressway, and the money required to reach the destination is 5 It is also possible to display the route on the display 34.

007 0 Note that if no escape route is found in step S44 (step S44 o), the CP 3 searches for a predetermined number of steps (step S46).

For example, if there are specific points or specific points with a possibility of accident occurrence near the destination, you cannot reach the target point if you do not get the specific point or specific points. This is one example.

[0071] Also, when searching, for example, by operating the input chair 3, the navigation 3 may be set in advance. However, if the conditions for the search are not set, the fact may be announced and the predetermined conditions may be set separately.

0072 Then, the result according to the predetermined condition is displayed on the display 34 (step

4 5), end the series of works. If there are multiple results, as described above, the result may be displayed on the display 34 depending on the display state set by operating the input device 3. Then, using 5 and 6, we will simply explain the conditions when conducting a search.

007 35 is a diagram showing an example of the result displayed on the display. At the time of searching, for example, the number of times a vehicle passes through a specific point with an accident possibility before reaching the destination can be set to a predetermined number or less. As shown in 5, this is an example of the result when the number of times a vehicle passes through a specific point with an accident possibility before reaching the destination is 3 or less. In addition, points 5 3 to 5 7 indicate specific points with the possibility of accident occurrence.

As shown in 007 45, the destination point is shown from the start position 5 which shows the vehicle

As a result up to 52, 5 of 5, 52 of 2 and 53 of 3 are displayed. Point 5 is a route that passes through point 5 3 5 4 5 5 3 which is a specific point of accident occurrence potential. In addition, 52 of 2 is a route that passes through 2 of 5 6 5 7 which is a specific point of accident occurrence possibility. In addition, 53 in 3 is a route that passes through point 57, which is a specific point of accident possibility. Here, for example, the route that passes through points 5 3 to 5 5 and point 5 7 which are specific points of the accident occurrence probability, is not displayed on the display 3 4 as a result. In addition, if the conditions for searching are set such that the number of times a vehicle passes through a specific point with an accident occurrence probability before reaching the destination point is set to the minimum number, 52 is not displayed as a result on display 34. Then, only 53, which has the least number of trips through a specific point with the possibility of accident occurrence, is displayed on the display 34 as the result 53. For example, if the vehicle is the destination, An explanation will be given for the case where the number of times of passing through a specific fault occurrence probability is set to a predetermined number or less before reaching FIG. 6 is a diagram showing another example of the result displayed on the display. This is an example of the result shown in Fig. 6 when the number of times a vehicle passes through a specific fault occurrence probability route is 3 or less before reaching the destination. Items 6 3 to 6 7 show the identification of accident probability.

As shown in 006-6, the destination point is shown from the start position 5 which indicates the vehicle position.

As a result up to 5 2, 6 of 2, 62 of 2 and 63 of 3 are displayed. No. 6 is a route that goes through 2 to 6 3 6 4 which is a specific possibility of accident occurrence. In addition, 62 of 2 is a route that goes through 3 of 6 4 6 5 6 6 which is a specific example of accident possibility. In addition, 63 in 3 is a route that goes through To 67, which is the identification of accident probability.

Here, for example, the route that goes through 4 of Toll 6 3 and To 6 5 to 6 7, which are the specifics of the accident possibility, is not displayed on the display 3 4 as a result. In addition, if the condition for searching is set to be the minimum number of times that a vehicle passes through a specified fault occurrence probability before reaching the destination, for example, The 62 of 2 is not displayed on the display 3 4 as a result. Then, it goes through the accident probability identification Only the 63 with the lowest number of 3 are displayed on the display 34.

In addition, it is possible to set the condition for the search as, for example, the length of the vehicle passing through the specified probability of accident occurrence before reaching the destination point is less than a predetermined length. Physically, for example, tog 6 3 to 6 7 are added with the information of each g as additional information. Then, calculate the distance between the specified accident potentials included in the searched route using the above report. Based on the result of this calculation, only the routes that are less than the predetermined value that are arbitrarily set are displayed on the display 34.

Furthermore, it is possible to set the conditions for the search so that, for example, the length of the vehicle passing through the specified fault occurrence probability path is the shortest before the vehicle reaches the destination. In this case, based on the calculation results calculated using the above report, only the route with the shortest distance between the identified routes with the accident occurrence probability included in the searched route is displayed on the display 34. .

Moreover, it is also possible to add weight information related to an accident to a specific point or specific point of the accident occurrence probability. The weight related to the accident is, for example, a score related to the accident occurrence probability issued by the above-mentioned dry function, or the type of accident that actually occurred. Physically, for example, by setting a higher score for accident probability for points or points where the vehicle is in a dangerous driving state than for points or points where the vehicle could be in a dangerous driving state, Assess the severity as high point or high.

Further, it is also possible to configure the search by further adding a condition in which the weighted information regarding the accident is added to the above-mentioned search-related condition. In this case, for example, you may give priority to the predetermined condition set for. Physically, for example, if the highest priority is given to conditions that include weighted information on accidents when searching, first of all, the critical points or points where the accidents occurred should be searched for. Ok. Therefore, the number of times that an accident may occur through a specific point or a specific route may be less than a predetermined number. It is also possible to make a search.

In addition, considering that the time required to reach the destination is increased by avoiding all the specific points or specific points with the possibility of occurrence, the time required to reach the target point is set. You can configure it so that you can specify it. For the required time, operate input chair 3 to enter the specific time. In addition, the power for the required time may be set together with the power at the destination, for example.

When the required time is entered, Navigation 3 searches for a specific location or specific avoidance point that may cause an accident, taking into account the entered required time. You can also do this after multiple results of the required time are displayed. If the time required to reach each target point of the indicated number is different, the required time can be used to increase the number of fruits displayed on the display 34. it can.

008 For example, among the results displayed on the display 34, when a trip to actually move is set, the set trip does not include the specific location or specific location of the accident possibility. If so, it may be configured to notify that effect.

Also, when passing through a specific point or a specific point with the possibility of an accident, the speaker 3 may output a warning sound, etc. to call attention. Furthermore, for example, it may be configured such that an accident report regarding an accident that occurred in the past at a fixed point or a specific point is determined, and the appropriate mobility for actually passing through the fixed point or the specific point is notified.

008 It is to be noted that if the vehicle deviates from the avoidance point displayed on the display 34 while the vehicle is moving to the target point along the avoidance point searched by the navigation 3, the navigation 3 may be configured to display the results on the display 3 4 instantly.

Furthermore, when the vehicle deviates from the avoidance point and there is a specific point or specific point with the possibility of accident occurrence, In the event of a situation, you may be configured to output a warning sound from the speaker 3 to notify the danger to the user.

When searching for a destination up to the destination, all of the accidents recorded by the driver's function, the quotient of the quotient, the specific point or specific point, or the communication 35 are used to connect via the network. You can use the road data acquired from the road network data (see below, report) to search for it, or you can configure it like Gino.

0099 For example, it may be configured such that the latest information is reported within a predetermined period to find the destination to the destination. Physically, for example, search for the latest report within a year. In addition, for example, it may be configured to search for the destination to the destination using the information within the past fixed period. Physically, for example, search for information within the winter period of the previous year.

Further, for example, the configuration may be such that the information is searched for according to the zone in which the vehicle is moving. Physically, for example, when searching for avoidance during the daytime, search for information during the daytime, not during the nighttime. In addition, for example, it may be configured to search using information according to the vehicle. Physically, for example, the vehicle

), It is not for normal searching. As described above, since it is possible to search for the destination up to the destination using the information according to the situation, it is possible to obtain the result of avoiding the specific location or the specific location according to the situation.

As described above, according to the present implementation, it is possible to search for a practical point that avoids a specific point or a specific point where an accident is likely to occur. For this reason, the Z can move to the destination by avoiding a specific point or a specific point where an accident is likely to occur, thereby improving safety.

In addition, when searching for a route, it is possible to search for a route using an accident occurrence recorded by the driver, a quotient specified point or a specified quotient of the note. Wear. For this reason, it is possible to avoid a point or point where the vehicle could be in a dangerous driving state in the past, or avoid a point or a specific point where the vehicle was in a dangerous driving state in the past and move to the destination point. It is possible to improve safety.

In addition, the route is searched for automatically using the specific location or specific point of the accident probability recorded by the driver, which is not intended by the user. For this reason, it is not necessary to perform operations such as putting all the specific points or specific points with the possibility of occurrence on the map data by the operation of the user. As a result, the information recorded by the driver function can be used effectively, and it is possible to search for a specific point or a route that avoids a specific point where an accident can occur with a single operation. .

In addition, even if a route that can avoid all the specific points or specific points with the possibility of occurrence is not found, it is possible to search for the route based on the predetermined conditions set by the It is possible to search for routes with the possibility of accident occurrence as much as possible. For this reason, the Z can move to the destination by avoiding a specific point or specific point where an accident is likely to occur, and can improve safety.

In addition, if the result contains a specific point or specific point with the accident occurrence potential, in order to notify the fact to the The, the specific point or specific point with the accident occurrence potential shall be notified in advance. It can be confirmed and the movement to the destination can be performed more safely.

0097 In addition, when searching for a route, the

Since it is possible to search for the road to the destination point using the information, it is possible to obtain accurate results in consideration of the running condition and running status of the vehicle. For this reason, the Za moves to the destination on the basis of accurate results, which can further improve safety.

The route described in the present embodiment can be realized by executing the program prepared in advance by a computer such as a so-called computer workstation. This program is It is executed by being recorded on a recording medium that can be read by a computer such as COO and by being read from the recording medium by a computer. Also, this program may be a body that can be distributed via a network such as the Internet.
