[0013] (Embodiment)

(Functional configuration of information providing device) The functional configuration of the information providing apparatus according to this embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing an example of a functional configuration of the information providing apparatus according to the present embodiment. As shown in FIG. 1, the information providing apparatus 100 includes an acquisition unit 101, a determination unit 102, a recording unit 103, and an output unit 104.

The acquisition unit 101 acquires behavior information regarding the behavior of the moving object. The behavior information includes, for example, the current position information of the moving body, information on the speed of the moving body, tilt angle information, traveling direction information, lateral G (Gravity) information, information on the steering gear, information on the acceleration / decelerator, and Information that includes at least one of the information on the direction indicator. Specifically, this behavior information is calculated using, for example, a received wave from a GPS satellite received by a GPS receiver mounted on a moving body, or output values from various sensors provided on the moving body. Information.

The determination unit 102 determines the traveling state of the moving body using the behavior information and the map information acquired by the acquisition unit 101. The determination of the running state is performed, for example, by comparing the current position information of the moving object with the map information and determining whether or not a predetermined change has occurred in the behavior of the moving object at the current position of the moving object on the map. The map information is information such as road shape data composed of nodes and links, and image data drawn using features related to facilities and other terrain (mountains, rivers, land).

[0016] Specifically, the determination unit 102, for example, when the moving body is traveling on a road where the temporary stop point is on the map, is based on information on the speed of the moving body. Judgment is made that the driving condition is dangerous, for example, when stoppage cannot be confirmed before the stop point.

The recording unit 103 accumulates the determination result determined by the determination unit 102 and records it in a storage unit (not shown). In addition, when the determination unit 102 determines that the moving state of the moving object is dangerous, the recording unit 103 associates the position of the moving object on the map and the content of the moving object with each other at the time of the determination. Are recorded in the storage unit together with the determination result. Therefore, when the traveling state of the moving body is dangerous, the location (traveling location) on the map where the traveling is performed by the recording unit 103 and the content of the traveling are recorded in association with each other.

[0018] Based on the determination result determined by the determination unit 102, the output unit 104 detects the customer of the moving object. Outputs information on objective driving safety (hereinafter referred to as “driving safety information”). The driving safety information refers to information for objectively determining whether or not the moving body has traveled in accordance with the traffic condition data specified in the map information.

[0019] The output unit 104 outputs the traveling safety information by at least one of display output and audio output. Furthermore, the output unit 104 outputs the transition state of the traveling safety information based on the determination result recorded by the recording unit 103. Further, the output unit 104 outputs scoring information calculated by adding a predetermined coefficient to the determination result as the traveling safety information to be output. Specifically, the scoring information is information that is numerically expressed by multiplying a predetermined coefficient based on the content of the behavior of the moving object (eg, the degree of speed change) recorded along with the judgment result. Say.

[0020] (Information provision processing procedure of information provision apparatus)

Next, information providing processing by the information providing apparatus 100 will be described. FIG. 2 is a flowchart showing an example of the contents of the information providing process by the information providing apparatus. In the flowchart of FIG. 2, the information providing apparatus 100 first acquires the movement information of the moving body by the acquisition unit 101 (step S201). The behavior information is information including the current position information of the moving body and the various information described above.

Next, the traveling state of the moving body is determined by the determination unit 102 using the behavior information acquired by the acquisition unit 101 and, for example, the map information provided in the information providing apparatus 100 in advance. (Step S 202). The traveling state is determined by determining that the traveling state is dangerous, for example, when a moving body enters a road where entry is prohibited, using these pieces of information.

[0022] Finally, based on the determination result determined by the determination unit 102, the determination result recorded by the recording unit 103, and the like, the traveling safety information of the moving body is output (step S203), A series of information providing processing according to the flowchart ends. In the output process in step S203, even if the driving safety information is output by video output or audio output, scoring information is calculated by multiplying the driving safety information by a predetermined coefficient, and the calculated scoring information is calculated. Even if it outputs.

[0023] As described above, according to the information providing apparatus 100 that works on the present embodiment, the mobile object The traveling safety information can be output based on the determination result of the traveling state. As a result, for example, it is possible for a mobile user to objectively grasp his / her driving state, and to encourage more safe driving and to add entertainment to driving. Become.

[0024] Specifically, the information providing apparatus 100 records, for example, the travel location and the content of the behavior when the travel state of the moving body is determined to be dangerous, so that the user can This information can be objectively presented (output) as reference driving safety information for preventing traffic accidents and traffic violations, and contributes to future safe driving (next driving).

[0030] Further, the route search program searches for an optimum route from the departure point to the destination point using map information or the like recorded on the optical disk 307 to be described later. Here, the optimal route is the shortest (or fastest) route to the destination or the route that best meets the conditions specified by the user. In addition, the route search program may search not only the destination point but also a route to a stop point or a rest point (via destination point), for example. The guidance route searched by executing this route search program is output to the audio IZF 308 or the video IZF 312 via the CPU 301, for example.

[0033] The map information display program determines the display format of the map information displayed on the display 313 by the video I / F 312 and displays the map information on the display 313 according to the determined display format.

[0034] The communication program appropriately selects (changes) a communication method of information transmitted and received by the communication IZF 314. The database creation program collects and compiles various information handled by the navigation device 300 into a predetermined database format.

The optical disk 307 is a detachable recording medium from which data is read by the control of the optical disk drive 306. As the optical disc 307, for example, a writable recording medium can be used. In addition to the optical disk 307, the removable recording medium may be an MO or a memory card.

As an example of information recorded on a recording medium such as the magnetic disk 305 or the optical disk 307, there is map information used for route search and route guidance. The map information includes background data that represents features (features) such as buildings, rivers, and the ground surface, and road shape data that represents the shape of the road. Rendered in 2D or 3D.

[0039] The road shape data further includes traffic condition data. Traffic condition data includes, for example, the presence or absence of traffic lights and pedestrian crossings for each node, the presence or absence of highway entrances and junctions, the length (distance) for each link, road width, direction of travel, road type (highway) , Toll roads, general roads, etc.).

[0040] Further, the traffic condition data may store past traffic information obtained by statistically processing past traffic information based on the season / day of the week "large consecutive holidays" and the like. Navigation device 3 In 00, information on traffic jams currently occurring is obtained from road traffic information received by communication IZF 314, which will be described later, but it is possible to predict traffic jam conditions at specified times based on past traffic jam information.

[0041] Further, the traffic condition data may include, for example, traffic rule information relating to traffic rules determined for each road. The traffic rule information is, for example, information such as a temporary stop position on the road or whether or not one-way traffic, speed limit, whether or not a special vehicle is allowed to pass, whether or not there is a restricted time zone, and right / left turn restrictions. As will be described later, the navigation device 300 determines the traveling state based on the traffic regulation information, the current position information of the vehicle, and the behavior information.

In the present embodiment, the force for recording the above-described map information or the like on a recording medium such as the magnetic disk 305 or the optical disk 307 is not limited to this. The map information or the like may be provided outside the navigation device 300, for example, not being recorded only in the one integrated with the hardware of the navigation device 300. In this case, the navigation device 300 may acquire map information via the network through the communication IZF 314, for example. The map information acquired in this way is stored in the RAM 303, for example.

The audio IZF 308 is connected to a microphone 309 for audio input and a speaker 310 for audio output. Audio received from the microphone 309 is AZD converted in the audio IZF308. In addition, sound is output from the speaker 310. Note that sound input from the microphone 309 can be recorded on the magnetic disk 305 or the optical disk 307 as sound data.

The video IZF 312 is connected to, for example, a video input camera 317 and a video output display 313. Specifically, this video I / F 312 includes, for example, a graphic controller that controls the entire display 313, a buffer memory such as VRAM (Video RAM) that temporarily records image information that can be displayed immediately, and a graphic controller. Force It is configured by a control IC that controls display of the display 313 based on the output image data.

The display 313 displays icons, cursors, menus, windows, or various data such as characters and images. As this display 313, for example, a CRT, a TFT liquid crystal display, a plasma display, or the like can be adopted. Further, a plurality of displays 313 may be provided in the vehicle. In this case, for example, there are a display 313 disposed on the driver seat and the passenger seat side, and a display 313 disposed on the rear seat side.

Communication IZF 314 is connected to a network via radio and functions as an interface between navigation device 300 and CPU 301. In addition, the communication I / F 314 is connected to a communication network such as the Internet via wireless, and also functions as an interface between the communication network and the CPU 301.

[0048] Communication networks include LANs, WANs, public line networks and mobile phone networks. Specifically, the communication IZF314 is composed of, for example, an FM tuner, a VICS (Vehicle Information and Communication System) Z beacon receiver, a radio navigation device, and other navigation devices, and traffic congestion distributed from the VICS center. Road traffic information such as traffic regulations.

[0049] In addition, the GPS unit 315 receives radio waves from GPS satellites and calculates information indicating the current position of the vehicle. The output information of the GPS unit 315 is used when the CPU 301 calculates the current position of the vehicle together with output values of various sensors 316 described later. The information indicating the current position is information specifying one point on map information such as latitude / longitude 'altitude.

[0050] Various sensors 316 are information that can determine the position and behavior of a vehicle, such as a vehicle speed sensor, an acceleration (G) sensor, an angular velocity sensor, a rudder angle sensor, a direction sensor, a winker sensor, a brake sensor, and an axenore sensor. Is output. The output values of the various sensors 316 are used for the calculation of the current position by the CPU 301 and the measurement of the amount of change in speed and direction. This makes it possible to analyze various dynamics such as sudden braking and sudden handle as the behavior of the vehicle.

[0051] The camera 317, for example, captures images inside and outside the vehicle and outputs them as image data. this An image captured by the camera 317 can be recorded as image data on the magnetic disk 305, the optical disk 307, or the like.

[0053] (Information provision processing procedure of navigation device)

Next, the information provision processing procedure of the navigation apparatus 300 that works on the present embodiment will be described. FIG. 4 is a flowchart showing an example of the information provision processing procedure of the navigation device which is useful in this embodiment. Here, the travel safety information output by the navigation device 300 includes the scoring information calculated by multiplying the determination result by a predetermined count, and the position of the vehicle on the map at the time of determination that the driving state is dangerous. (Dangerous driving location) and behavior details (dangerous driving content) will be described. In the following, the same parts as those already described are denoted by the same reference numerals and the description thereof is omitted.

In the flowchart of FIG. 4, the navigation apparatus 300 first determines the vehicle running state objectively based on the input information input through the input device 311 or the like. It is determined whether or not the ability to execute the scoring mode (step S401). If it is determined not to execute the scoring mode (step S401: No), the series of information provision processing according to this flowchart is terminated.

[0055] When it is determined that the scoring mode is to be executed (step S401: Yes), vehicle behavior information is acquired based on the output values from the GPS unit 315 and the various sensors 316 (step S402) and magnetic The map information is also acquired by the power of the disk 305 and the optical disk 307 (step S403).

[0056] After acquiring these pieces of information, the CPU 301 determines whether or not the running state of the vehicle is normal (step S404). Here, the traveling state in step S404 is correct. The process of determining whether or not the vehicle is normal, that is, whether or not the running state is dangerous will be described. In this determination process, basically, the current position of the vehicle is compared with the position on the map.

[0057] For example, when information from a steering angle sensor is used as vehicle behavior information, the CPU 301 detects a change in the turning angle of the steering wheel of the vehicle based on an output value from the steering angle sensor, and maps The running state is judged based on whether or not there is a rapid change in the upper road. When it is determined that there is an abrupt change and the running state is not normal, the position of the vehicle and the content of the behavior at the time of determination are recorded along with the degree of change of the turning angle.

[0058] Further, for example, when a GPS satellite force received wave is used as vehicle behavior information, the CPU 301 detects the vehicle road follow-up performance at regular intervals, for example, based on the GPS satellite force received wave. Then, the driving state is determined based on whether or not there is a sudden change exceeding a predetermined value on the road on the map. If there is a sudden change and it is determined that the running condition is not normal, the degree of change in road following performance and the position and behavior of the vehicle at the time of determination are recorded.

[0059] Further, for example, when the direction sensor force information is used as the vehicle behavior information, the CPU 301 detects a change in the traveling direction of the vehicle based on the output value from the direction sensor, and the road on the map. On the other hand, the running state is determined based on whether or not the force has a sudden change greater than a predetermined value. If there is a sudden change and it is determined that the driving condition is not normal, the vehicle position and behavior details at the time of determination are recorded along with the degree of change in the heading direction.

[0060] Further, for example, when information from the winker sensor is used as vehicle behavior information, the CPU 301 detects the accuracy of the direction indication of the vehicle based on the output value from the winker sensor, and the road on the map. On the other hand, the running state is determined based on whether or not the direction instruction is incorrect. If it is determined that there is a direction indication error and the driving condition is not normal, record the position of the vehicle and the contents of the behavior at the time of determination along with the number of direction indication errors.

[0061] Further, for example, when information on the brake sensor force is used as vehicle behavior information, the CCU 301 detects the use state of the vehicle brake based on the output value from the brake sensor, and displays it on the map. For example, if the road is The running state is determined based on whether or not the key is used. If the brake is not used, such as before the temporary stop, and it is determined that the running condition is not normal, record the vehicle's position and behavior at the time of determination along with the brake usage condition.

[0062] Further, for example, when information from the accelerator sensor is used as vehicle behavior information, the CCU 301 detects the use state of the accelerator of the vehicle based on the output value from the accelerator sensor, and the road on the map. On the other hand, for example, the running state is determined based on whether or not the accelerator is used before the temporary stop or entry prohibition. If it is determined that the accelerator is still in use before the temporary stop and the driving condition is not normal, record the vehicle's position and behavior at the time of determination along with the accelerator usage condition.

[0063] Further, for example, when vehicle speed sensor force information is used as vehicle behavior information, the CPU 301 detects the vehicle speed state based on the output value of the vehicle speed sensor force, and displays the road on the map. On the other hand, there is an abrupt change more than the predetermined value, for example, based on whether the vehicle was accelerated (decelerated) just before the temporary stop or entry prohibition! Hurry up and determine the running condition. If there is an abrupt change, acceleration is performed before the pause (deceleration is not performed), and it is determined that the running state is not normal, the vehicle position at the time of determination is determined along with the degree of acceleration / deceleration change. Record the behavior and behavior.

[0064] Further, for example, when information on acceleration (G) sensor force is used as vehicle behavior information, the CPU 301 detects the size of the vehicle G based on the output value from the acceleration (G) sensor. The driving condition is determined based on whether or not the power on the road on the map has changed more than a predetermined value. If it is judged that there is a sudden change and the driving condition is not normal, the position of the vehicle and the contents of the behavior at the time of judgment are recorded together with the degree of change in acceleration (G).

If it is determined that the running state of the vehicle is normal (step S404: Yes), the process proceeds to step S402 to acquire vehicle behavior information. If it is determined that the vehicle is in a normal driving state (step S404: No), that is, if it is determined that the driving state is dangerous, the vehicle's dangerous driving location and the dangerous driving As the contents, the position of the vehicle on the map and the contents of the behavior change of the vehicle are included in the determination result and recorded (step S405). [0066] Then, scoring information is calculated by multiplying the recorded determination result by a predetermined coefficient (step S406), and the vehicle is stopped based on the output values from the GPS unit 315 and various sensors 316. It is determined whether or not the force has been applied (step S407). If it is determined that the vehicle has not stopped (step S407: No), the process proceeds to step S402 to obtain the vehicle behavior information.

[0067] When it is determined that the vehicle has stopped (step S407: Yes), the scoring result is displayed as the calculated scoring information on the display screen of the display 313 via the video IZF 312 (step S408). After the scoring results are displayed, it is determined whether or not the displayed scoring results can be recorded based on, for example, input information input through the input device 311 (step S409).

[0068] When it is determined to record the scoring result (step S409: Yes), the scoring result is recorded in the RAM 303, the magnetic disk 305, the optical disk 307, etc. by the CPU 301, the magnetic disk drive 304 or the optical disk drive 306 (step S409). S410). If it is determined that the scoring result is recorded or that the scoring result is not to be recorded (step S409: No), the scoring is performed based on, for example, input information input through the input device 311 or the like. It is determined whether or not to end the mode (step S411).

[0069] When it is determined that the scoring mode is not to be ended (step S411: No), the process proceeds to step S402 and the vehicle behavior information is acquired. If it is determined that the scoring mode is to be terminated (step S411: Yes), the series of information provision processing according to this flowchart is terminated. In step S408, the scoring result is displayed and output, but it may be output by voice instead of displaying. In this flowchart, the scoring results are output as driving safety information, but this is not restrictive. Here, a specific example of the display process in step S408 will be described.

FIG. 5 is an explanatory diagram showing an example when the scoring results are displayed on the display screen. FIG. 6 is an explanatory diagram showing an example when a map screen based on a scoring result is displayed. As shown in Fig. 5, on the display screen of the display 313, there are a risk display column 502, a dangerous driving content display column 503, and a dangerous driving display as items that objectively indicate the driving state of the vehicle. A place display field 504, a point display field 505 for the current travel, and a point display field 506 for the previous travel are displayed.

[0071] The risk level display column 502 is a column that displays an objective risk level according to a classification such as "high, medium, low" as a result of scoring based on the travel content and travel location of the vehicle. The dangerous driving content display column 503 is a column that displays details of the dangerous driving such as “ignore pause” and “overspeed”. Further, the dangerous driving location display column 504 is a column for displaying the location where the dangerous driving has been performed in detail, such as “X XX prefecture X X town XX street vicinity”.

[0072] Further, the point display column 505 at the time of the current travel is a column for displaying the overall travel safety in the current travel by a score such as "72 points". The point display column 506 for the previous run is a column for displaying the overall travel safety in the previous run by a score such as “68 points”. The clear button 507 is a button that is pressed when clearing the display of each of these fields 502 to 506.

Here, for example, when the user moves the cursor 501 to select a desired scoring result and executes a more detailed display of the selected scoring result, the display screen of the display 313 displays FIG. As shown in FIG. 6, a location 601 where dangerous driving has been performed on the road 602 may be displayed. In this way, the user can easily visually recognize in which place the dangerous driving has been performed.

[0074] Note that, as the scoring result, for example, the content and location of dangerous driving may be displayed in a table format or displayed in a graph format based on the recorded determination result. Further, instead of the display output or together with the display output, these pieces of information may be output by sound output.

[0075] As described above, according to the navigation device 300 of the present embodiment, the scoring information calculated as the traveling safety information based on whether the traveling state of the vehicle is normal or not is determined. The scoring results can be displayed. As a result, for example, the user of the vehicle can be made to objectively grasp his / her traveling state from the score or the like. For this reason, it is possible to encourage more safe driving and add entertainment to driving.

[0076] Further, according to the navigation device 300, the determination result of the running state and the like are recorded. It is possible to output the recorded information in a table format or a graph format. This makes it possible to use data effectively.

[0077] It should be noted that the travel safety information in the navigation device 300 described above is made available in cooperation with stores such as car dealers, for example, and measures such as giving a privilege to excellent drivers are taken. The data can be used for specific processing of places where dangerous driving can occur, and can be expected to be used more effectively.

Note that the information providing method described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed when the recording medium force is also read by the computer. The program may be a transmission medium that can be distributed through a network such as the Internet.
