Description

  The present invention relates to an information output device that outputs information associated with operation of a vehicle.

  In recent years, attempts have been made to record driving operation contents, vehicle conditions, and the like in a recording device mounted on the vehicle to make it useful for safe driving. For example, when a driver performs a driving operation with a high degree of danger, the details of the driving operation and the state of the vehicle at that time are recorded together with the point information, and recorded when the point is reached next time. There has been proposed a driving assistance device that performs alerting (for example, alerting “please pay attention to slip”, etc.) based on the stored information.

  However, there is a gap between the point at which the alert is issued and the point at which the high-risk driving operation is performed. It ’s hard to tell if it ’s dangerous. Therefore, there may be a case where a driving operation with a high degree of risk is performed again. On the other hand, when a driving operation with a high degree of danger is performed, if the fact is to be notified, the driver himself / herself recognizes that fact, so that it feels bothersome or dangerous. Immediately after encountering the driver, the driver may be upset and may not be able to analyze his driving operation calmly.

Therefore, in order to solve such a problem, in the vehicle driving support apparatus described in Patent Document 1 below, when a driving operation with a high degree of danger occurs, a predetermined time elapses without immediately outputting an alarm. When the driver's mental state is stabilized, a warning guidance including the content of the driving operation with a high degree of danger is notified (see paragraph “0038” of Patent Document 1).
JP 2007-65997 A

  However, if the warning guidance is given when the driver's mental condition is stable, the time will elapse from the point of time when the driving operation with a high degree of danger is performed, so the driver may be able to drive dangerously at any point. It is difficult to tell if there was an operation. This is particularly noticeable when it takes a long time for the driver's mental state to stabilize.

  Therefore, when the time point at which a driving operation with a high degree of danger occurs and the time point at which the content is notified are shifted, the time point at which a driving operation with a high degree of risk has occurred must be notified in an identifiable manner. Specifically, for example, a method in which a point at which a driving operation with a high degree of danger occurs is first notified, and then the content of the driving operation, the details of the danger, and the like are sequentially notified. That is, a method for reporting a plurality of pieces of information collectively is conceivable. However, the method of reporting a plurality of pieces of information collectively causes the following problems when a driving operation with a high degree of risk is performed at a plurality of points.

  As a first problem, there is a problem that it takes time for notification because there is a lot of information to be notified. A second problem is that information that the driver really wants is buried in unnecessary information. As a third problem, if the driver wants to report again for reasons such as the driver missing or overlooking the reported content, until the driver arrives at the information desired by the driver. It may be a problem that it takes time and effort.

  The present invention has been considered in view of such a problem, and an object thereof is to provide an information output device that allows a driver to easily confirm contents related to an event that occurs during operation of a vehicle. To do.

The information output device according to claim 1, which has been made to solve the above-described problem , specifies a body part to be watched by the driver acquired by the sensing information acquisition unit when the risk is determined by the risk determination unit. Storage control means for associating each of a plurality of types of sensing information consisting of sensing information to be performed and sensing information for specifying a site to be noted of the vehicle and storing the information in a storage means for a predetermined period. The association may be performed from any viewpoint, but is particularly preferable from the viewpoint of time, the position of the vehicle, the target fact, and the like. The information output device outputs an icon indicating a plurality of types of sensing information at the start or end of driving of the vehicle, and accepts a selection instruction corresponding to the icon as an operation instruction via the accepting unit. Then, out of a plurality of types of sensing information stored in the storage unit, the type of sensing information corresponding to the icon selected and designated by the operation instruction is read out from the storage unit and output , and any one type of sensing is performed. When the accepting means accepts an operation instruction for selecting an icon of a different type from the sensing information being output from the state in which the information is read from the storage means and outputted, it corresponds to the icon selected by the operation instruction. a kind, an output control means which can be brought into a state in which to output sensing information associated string information in the output from the storage means. Needless to say, the sensing information to be output may be output in a format that the user can easily understand.

  According to such an information output device, the sensing information to be output can be switched and output based on the association by the user's intention. That is, it is possible to easily output desired sensing information by tracing the sensing information based on the association without outputting all the sensing information. Therefore, the first to third problems described above can be solved, and the driver can easily confirm the contents related to the event that occurred during the operation of the vehicle.

In the information output device according to claim 2, the output control means among the plurality of types of sensing information stored in the storage means and to output the one type of sensing information or displacement have been read from the memory means From the state, based on the operation instruction received by the receiving means, it is possible to change the state of the sensing information being output at a different point in time, and separately from the information at another point in the output. If the receiving unit operation instruction to select the type of icon is accepted, a type corresponding to the icon selected indicated by the operation instruction, the sensing information associated string to another point of the information in the output It is also possible to read out from the storage means and make it output.

  For this reason, for example, it is possible to output the deceleration information retroactively, and when the user specifies the point of sudden deceleration, the information output device can immediately output the information of the vehicle speed at that point. . That is, the user can immediately know both pieces of information at the same time without outputting the information on the deceleration and the information on the vehicle speed sequentially in the past. Accordingly, the driver can more easily confirm the contents related to the event that occurred during the operation of the vehicle.

In the information output device according to claim 3, the output control means among the plurality of types of sensing information stored in the storage means and to output the one type of sensing information or displacement have been read from the memory means from the state, based on the operation instruction accepting unit has accepted, to output can be a state where the output detailed information of the sensing information that has, on its, another type is the detailed information in the output icon When the accepting means accepts an operation instruction to select the sensing information, it reads out the sensing information associated with the detailed information being output from the storage means and outputs the type corresponding to the icon instructed by the action instruction. It can also be made into the state made into.

  For this reason, for example, from the state in which the steering angle information including binary information indicating whether or not the steering angle has changed by 30 degrees or more is output, the steering angle information indicating the change in the steering angle is output with a resolution of 256. In addition, for example, deceleration information associated with a specific rudder angle represented by a resolution of 256 can be output. That is, the user can immediately know the deceleration information associated therewith by, for example, refining only the steering angle information without refining each of the steering angle information and the deceleration information independently. it can.

By the way, when receiving the operation instruction from the user, it is preferable that the type of sensing information is represented by an icon and output so that the user can easily understand the content of the sensing information. That is, the output control means outputs the type of sensing information by an icon, an input corresponding to the icon, receiving via a receiving means, not good when adapted used as an operating instruction.

If this is the case, the user can intuitively select the sensing information to be output by looking at the icon, which makes the information output device easy to use.
In addition, there are character icons, graphic icons, etc. as icons, but in particular, an icon that models an entity corresponding to sensing information, and the sensing information corresponding to the icon satisfies a predetermined condition It is preferable that a mark is added to the location of the icon corresponding to the sensing information (claim 4 ). The “predetermined condition” may be, for example, a condition “exceeding a preset threshold value (a value at which occurrence of danger can be estimated)”.

  If it is in this way, the user can select the sensing information to output intuitively by looking at the icon, and the usability of the information output device is better. In addition, since a mark is added to the location of the icon corresponding to the sensing information, the user can check the presence and location of the sensing information satisfying a predetermined condition without checking the sensing information itself by looking at the sign. Can know.

Note that the above-mentioned “sign” is particularly good when the corresponding sensing information is configured in a manner indicating the degree when the corresponding sensing information is applied to a predetermined scale (claim 5 ). The phrase “configured according to the mode indicating the degree” as used herein refers to determining, for example, the size, color, shape, and the like of the sign according to the degree when measured on a predetermined scale.

  If this is the case, the user can know the degree of sensing information corresponding to the icon (for example, the maximum value or average value in the entire sensing information) by looking at the sign added to the icon, The user can see it and select sensing information to be output.

Further, if the sensing information satisfies a predetermined condition, it may display indicating the number of times that satisfies the condition is added to the icon (claim 6). The “predetermined condition” may be, for example, a condition “exceeding a preset threshold value (a value at which occurrence of danger can be estimated)”.

  If it becomes like this, since the user can know directly the number of times the sensing information satisfies the predetermined condition from the icon, the user can appropriately select the sensing information to be output.

The output control means may be configured to estimate an accident that may occur based on the sensing information stored in the storage means and further output the state of the accident by animation (claims). 7 ).

If it becomes like this, the user can understand the situation which sensing information means more, and is useful for improvement of safe driving technology more.
Further, the risk determination unit generates a plurality of types of factor information based on the plurality of types of sensing information acquired by the sensing information acquisition unit, and one or a plurality of types of factor information among the generated types of factor information. When a predetermined condition set in each factor information is satisfied, it may be determined that a danger has occurred (claim 8 ). One factor information may be generated from one type of sensing information or may be generated from a plurality of types of sensing information.

  If it is in this way, risk determination can be performed appropriately by setting predetermined conditions appropriately. As a result, sensing information for a minimum necessary period can be stored in the storage means.

The storage control means associates each of a plurality of types of sensing information acquired by the sensing information acquisition means and sequentially stores them in the buffer means for a certain period of time, and when the danger determination means determines the danger, By transferring the information stored in the means to the storage means, each of the plurality of types of sensing information acquired by the sensing information acquisition means is linked and stored in the storage means for a predetermined period. (Claim 9 ).

  If this is the case, it is possible to use a storage means with a lower writing speed performance or a storage means with a limited number of writable times compared to the case where sensing information is stored directly in the storage means. That is, the cost of the information output device can be reduced.

Note that the functions as the above-described risk determination means, storage control means, or output control means may be realized by programs, respectively (claims 10, 11, 12 ). If such a program is executed by a computer built in the information output apparatus, the information output apparatus has the same operations and effects as the information output apparatus of the present invention described above. In addition, the program can be distributed using a network or the like, and the replacement of the program in the information output apparatus is easier than the replacement of the parts. Therefore, the function of the information output device can be easily improved.

[Description of operation]
Next, an information storage process and a screen output process which are executed by the control unit 16 of the information output apparatus 11 will be described.

(1) Information Saving Process First, the information saving process will be described with reference to the flowchart of FIG. Note that the information storage process is a process in which the control unit 16 starts executing at the start of operation (such as when the ignition switch is turned on).

  When starting the execution of the information storage process, the control unit 16 starts storing information in the buffer 17 (S105). The information stored here means information (raw data) that can be acquired via the communication interface 12, and the latest information can be stored for a certain period of time (for example, 30 seconds). . That is, old information more than a certain time ago is overwritten and erased. Each piece of information is stored in association with time so that each piece of information at a desired time can be specified later.

  Subsequently, the control unit 16 determines whether or not a condition for transferring information from the buffer 17 to the storage unit 13 is satisfied (S110). This transfer condition will be described later. If it is determined that the transfer condition is satisfied (S110: Yes), the process proceeds to S115. If it is determined that the transfer condition is not satisfied (S110: No), the present step remains until the transfer condition is satisfied.

  In S <b> 115 that proceeds when it is determined that the transfer condition is satisfied, the information currently stored in the buffer 17 is transferred to the storage unit 13. Then, the process returns to S110 described above. In addition, when there is no free storage area in the storage unit 13, it is preferable to notify the display unit 31 and the speaker 32 to that effect, and thereafter, the storage unit 13 is not stored. The information stored in the storage unit 13 may be deleted by an explicit operation by the user, or automatically deleted after a predetermined time has elapsed after the engine is started next time. It may be like this.

  Next, an example of the transfer condition described above will be described with reference to the explanatory diagram of FIG. In this example, it is determined whether or not the transfer condition is satisfied based on the three factors A, B, and C. Each factor may be any of the information input via the communication interface 12 (for example, information from the acceleration sensor itself) or generated from a plurality of information input via the communication interface 12. It may be information (for example, information indicating the degree of tension generated from a heart rate sensor, an electrocardiogram sensor, a sweat sensor, or a body temperature sensor).

  In the example of FIG. 3, when the value of the factor A exceeds the threshold value L1, and the value of the factor B exceeds the threshold value L2, the value of the factor C first changes from minus to plus. It is determined that the transfer condition is satisfied, and the information currently stored in the buffer 17 is transferred to the storage unit 13.

(2) Screen Output Processing Next, screen output processing will be described using the flowchart of FIG. The screen output process is a process in which the control unit 16 starts executing at the start of operation (such as when the ignition switch is turned on) and at the end of operation (such as when the ignition switch is turned off).

When starting the screen output process, the control unit 16 first causes the display device 31 to output an initial screen (S205). An example of the initial screen will be described later.
Subsequently, it is determined whether or not the operation unit 15 has accepted any operation instruction from the user (S210). If any operation instruction has been accepted (S210: Yes), the process proceeds to S215. If no operation instruction has been accepted (S210: No), the process remains at this step. If no operation instruction is received for a certain period of time, this processing (screen output processing) may be terminated.

  If it is determined that any operation instruction has been received, it is determined whether or not the operation instruction is an end instruction (S215). If it is determined that the instruction is an end instruction (S215: Yes), the present process (screen output process) is terminated. If it is determined that the instruction is not an end instruction (S215: No), the process proceeds to S220.

  In S <b> 220, which proceeds when it is determined that the instruction is not an end instruction, a screen instructed according to the operation instruction is generated from information stored in the storage unit 13 and output to the display device 31. A specific screen will be described later. When the screen is output, the process returns to S210 described above.

(3) Screen Example Next, an example of a screen output in the screen output process described above will be described.

This is different in that the icons for transition to the screen are displayed separately on the left and right sides of the screen (see, for example, icons 71a and 71c in FIG. 9A).

(H) Road surrounding screens C1 to C4
The road surrounding screens C1 to C4 are screens for displaying a part to be noted in the route process and detailed information about the part (see FIGS. 11 and 12). The screen transition method is basically the same as the surrounding screens A1 to A4, but the main display is displayed on the right side of the screen (for example, see the main screen 81c in FIG. 11A). The difference is that an icon for transitioning to a screen of a series is displayed on the left side of the screen (see, for example, icons 81a and 81b in FIG. 11A).

(I) Simulation screen P
The simulation screen P is a screen on which an accident animation at a place where an inappropriate operation has occurred is displayed (see FIG. 13). Accident animation is generated by identifying a template of an accident animation to be approximated based on information stored in the storage unit 13 at the time when an improper operation is performed, and selecting the identified template as inappropriate. Accident animation is generated by correcting the information based on the information at the time when the motion occurred.

[Effect of the embodiment]
According to the information output device 11 of the above embodiment, the information to be output to the display device 31 can be switched based on the association from the viewpoint that the target facts (time points) are the same (FIG. 5). Etc.). For example, when the user desires to display the car surrounding screen B4 while the personal surrounding screen A4 is displayed, the car surrounding screen B4 is directly displayed without returning to the initial screen O. be able to.

  Accordingly, it is not necessary to follow the initial screen O in order (initial screen O → car surrounding screen B1 → car surrounding screen B2 → car surrounding screen B3 → car surrounding screen B4). The problem that it takes time to display the screen is resolved. In addition, since unnecessary screens are not displayed, it is possible to avoid burying information that the user really wants. In addition, even when the user desires to display again due to reasons such as missing the screen, the time and effort required to reach the screen desired by the user can be reduced.

  Further, when receiving a screen transition instruction from the user, an icon that models information notified by the transition destination screen is displayed so that the user can give an instruction intuitively (see FIG. 6 and the like). For this reason, the user can issue a screen transition instruction by looking at the icon, which is convenient.

  Further, circles having different display locations, display sizes, and display colors (concentrations) are added to the icons in accordance with the content and degree of information notified on the transition destination screen (see FIG. 6 (b), FIG. 6 (c), etc.). For this reason, the user can know the degree of information displayed on the transition destination screen simply by looking at the circle added to the icon.

  In addition, there is a pattern in which a number indicating the number of occurrences of danger occurring during the route process is added to the icon (see FIG. 6B). Therefore, the user can know the number of danger occurrences occurring during the route process without looking at the transition destination screen.

  Further, an accident animation is generated based on the information stored in the storage unit 13, and the generated accident animation is displayed (FIG. 13). Therefore, the user can understand the situation that the selected information means.
