Description

  The present invention relates to a vehicle information providing apparatus.

  Conventionally, techniques for providing various types of information to a traveling driver have been proposed (see, for example, Patent Document 1 and Patent Document 2). Among these, in the technique described in Patent Document 1, it is evaluated whether or not the intersection is a cautionary intersection that is liable to make a driving mistake from the width, type, connection relationship, etc. of the intersection, and the intersection evaluated as cautioned. In front of, an alarm guidance voice is output together with a route guidance voice.

Further, in the technique described in Patent Document 2, it is determined whether or not it is necessary to provide information to the driver based on the state of the vehicle and the operation amount of the sensor group detected as the vehicle state amount and the operation amount of the host vehicle. Provide information when judged necessary. In this information providing operation, the driver's driving skill level is determined based on data (gaze frequency, gaze range, gaze distance, etc.) representing the gaze point obtained from the gaze point detection sensor, and according to the driving skill level. The timing for providing information is corrected.
JP-A-9-190596 JP 2001-163082 A

  The technique described in Patent Document 1 does not determine whether or not the driver has visually recognized an object to be watched after receiving the warning after outputting the warning guidance voice. Accordingly, it is assumed that the driver continues to output the alarm guidance voice even though the driver has watched the target to be watched, so the voice guidance is troublesome for the driver.

  In addition, the driver's driving behavior (straight, right turn, left turn, etc.) at an intersection changes the gaze direction to be noted and the time to complete the visual recognition in that gaze direction. It is considered that determining whether or not information provision is necessary leads to providing appropriate information to the driver. However, since the technique described in Patent Document 2 determines whether or not information provision to the driver is necessary based on certain conditions, the information provision is not appropriate for the driver.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a vehicle information providing apparatus capable of providing appropriate information to a driver.

The vehicle information providing device according to claim 1 determines whether the driving action of the driver of the own vehicle is a right turn, a left turn, or a straight drive at a specific point on the road where the own vehicle is about to travel. The driver action estimation means to be estimated and the attention area to be noted when the driver of the vehicle takes the driving action estimated by the driver action estimation means at a specific point on the road and all the attention area to be visually recognized Standard data storage means for storing standard data in which standard visual completion time and priority indicating warning rank for each attention target area are associated with each other, and standard data stored in the standard data storage means Visualization completion determination conditions for determining that the driver of the own vehicle has visually recognized the attention object existing in the line-of-sight direction to be noted from the driving behavior estimated by the driver behavior estimation means. Based on the detection results of the determination condition setting means for setting the attention target area and the standard visual recognition completion time, the visual line detection means for detecting the gaze direction of the driver of the own vehicle at a specific point on the road, and the detection result of the visual line detection means The visual recognition completion judgment condition is determined by individually checking the attention target area set as the judgment condition and determining whether or not the total time for confirming the set attention target area is equal to or longer than the standard visual recognition completion time. When the visual recognition completion determination means and the visual recognition completion determination means determine whether or not the visual recognition completion condition is satisfied, and it is determined that there is a caution target area that the driver has not confirmed. Warning generating means for generating a warning according to the priority for the attention target area that has not been confirmed.

As a result, it is possible to determine whether or not a warning for providing information to the driver is necessary according to the visual recognition completion determination condition corresponding to the attention target region and the visual recognition completion time, which changes depending on the driving behavior of the driver. Information can be provided .

According to the vehicle information providing apparatus according to claim 2 , history data indicating the number of times of forgetting to view the attention target area to be noted when the driver of the vehicle has taken a driving action in the past at a specific point on the road. a history data storage means for storing, as the attention object area visually remember a large number of times of the historical data, Ru includes a priority changing means for changing as the priority of the standard data with respect to the watched area increases. Thus, as noted target area visible forget a large number of times, increasing the priority of alarm generation, Ru can enhance the effect of preventing the visibility forgotten.

The vehicle information providing device according to claim 3 is a route search means for searching for a route to a destination where the host vehicle is to travel, and a route guide point setting for setting a guide point in the route searched by the route search means. And the driver behavior estimating means uses the guidance point set by the route guidance point setting means as the specific point on the road.

  Thereby, the driver action estimating means can estimate the driving action at the guide point of the route to the destination. In addition, as for a guidance point, it is desirable to include the branch point where a own vehicle needs to stop temporarily, a merge point, and an intersection. This is because a guidance point that needs to be temporarily stopped is likely to collide with another vehicle or a pedestrian.

According to a fourth aspect of the present invention , there is provided route guidance information setting means for setting guidance information at the guidance point set by the route guidance point setting means, and the driver behavior estimation means is based on the guidance information set by the route guidance information setting means. The driving behavior of the driver of the vehicle may be estimated.

  This is because the driver's driving behavior (straight, right turn, left turn, etc.) at the guidance point can be grasped from the guidance information. Note that the driving behavior of the driver may be estimated from a turn signal operation, a steering operation, or the like. Further, it may be estimated from the traveling lane of the own vehicle.

As described in claim 5 , the warning generation means may stop the generation of the alarm when the warning target area that the driver of the own vehicle has not visually recognized after the warning is generated. In this way, when the driver visually recognizes the attention target area that was not visually recognized before the warning occurred, the warning is stopped even if the driver visually recognizes the attention target by stopping the warning. Can no longer be output, and troublesomeness can be eliminated.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The vehicle information providing apparatus of the present embodiment shown in FIG. 1 is mounted on a vehicle, and includes a camera 1, a line-of-sight detection device 2, a personal authentication device 3, a navigation device 4, a display device 6, an audio output device 7, and these. It is comprised by the control apparatus 5 connected.

  The camera 1 captures the face image of the driver of the vehicle at regular time intervals, and sequentially outputs information of the captured face image to the line-of-sight detection device. The line-of-sight detection device 2 receives face image information from the camera 1 and uses this information to detect the line-of-sight direction of the vehicle driver (in other words, the direction of the central visual field of the driver) at regular time intervals. This line-of-sight direction is represented by an XY coordinate system in which the viewpoint of the driver of the host vehicle is the origin, the front-rear direction of the host vehicle is the X axis, and the vehicle width direction of the host vehicle is the Y axis. The line-of-sight detection device 2 sequentially outputs line-of-sight information representing the detected line-of-sight direction to the control device 5.

  The personal authentication device 3 is a device for identifying a driver of a vehicle. The personal authentication device 3 is a method for authenticating a driver by inputting a password set in advance for each driver, or biometrics (biometric authentication (fingerprint, voiceprint, iris of the pupil, etc.) ) Can be used. When authenticating the driver, the personal authentication device 3 outputs personal information (name, age, sex, etc.) of the driver to the control device 5.

  The navigation device 4 is composed of a position detector, a map database, a group of operation switches, and a control circuit connected to them, all of which are not shown, and the current position (latitude and longitude) of the vehicle detected by the position detector. The current position display function that displays the vehicle position mark indicating the coordinates of the vehicle) on the road map, and the so-called route that automatically searches for the optimal route from the departure point to the destination to form and display a guide route It has a guide function.

  In this route guidance function, when a destination is specified, a guidance route is calculated using a map database, and the guidance route is displayed on the display device 6 according to the progress of the vehicle. Map display and voice guidance at the intersection to be performed. Here, the point where the enlarged display of the map and the voice guidance are performed is set as the guidance point in the searched guidance route. Further, guidance information (right turn, left turn, straight ahead, etc.) at this guidance point is set.

  The guide points preferably include a branch point where the vehicle needs to temporarily stop, a junction point, and an intersection. This is because a guidance point that needs to be temporarily stopped is likely to collide with another vehicle or a pedestrian.

  The navigation device 4 controls own vehicle position information indicating the current position of the vehicle (coordinates of latitude and longitude), branch information included in the guide route, junction point, intersection information regarding the shape of the intersection, and navigation information including the guidance information. Output to the device 5.

  The display device 6 is a color display device, and displays a road map or a warning display described later. The voice output device 7 outputs a guidance voice of a guidance route, a warning voice, and the like from a speaker (not shown).

  As illustrated in FIG. 1, the control device 5 includes a visual recognition determination unit 51, a history data storage unit 52, a driver behavior estimation unit 53, a standard data storage unit 54, a determination condition setting unit 55, and a warning device control unit 56. It consists of functional parts.

  The driver behavior estimation unit 53 estimates the driver's driving behavior (right turn, left turn, straight ahead) at each guidance point on the guidance route from the guidance information included in the navigation information from the navigation device 4. Thereby, it is possible to estimate the driving behavior at the guide point of the guide route to the destination. Note that the driving behavior of the driver may be estimated from a turn signal operation, a steering operation, or the like. Further, it may be estimated from the traveling lane of the own vehicle. Information on the driving behavior estimated by the driver behavior estimating unit 53 is output to the determination condition setting unit 55.

  The standard data storage unit 54 completes the standard viewing for the gaze direction to be noted when the driver takes a right turn, left turn, or straight ahead driving action at a branch point, junction point, intersection, etc. Standard data in which time and priority are associated is stored.

  FIG. 2 shows line-of-sight directions (hereinafter referred to as attention target areas) S1 to S4 to be noted at intersections. The attention target areas S1 to S4 indicate areas in which it is determined whether the driver of the vehicle has confirmed (viewed) the attention target that may exist in each attention target area. Note that FIG. 2 shows an example of an intersection, and the attention target area at the branch point or the junction is set separately from the attention target area at the intersection.

  FIG. 3 shows a standard visual completion time (standard visual completion time) for an attention object that may exist in the attention object regions S1 to S4 when the driver takes a right turn, left turn, or straight driving action at the intersection. And standard data in which warning ranks indicating priority levels of warnings to be generated when each attention target area is not visually recognized are associated with each other.

  The standard viewing completion time is set based on the visual characteristics of a general driver. That is, generally, when a person visually recognizes an object, the line of sight tends to be fixed in the direction in which the object exists for about several hundred milliseconds. Therefore, the time of about several hundred milliseconds is set as the visual recognition completion time per attention object, and the time (or self-confirmation) when all of the attention target areas S1 to S4 are visually recognized (confirmation completion) with reference to this time. The time until the vehicle stops and restarts is set as the standard viewing completion time.

  The warning rank is basically a low warning rank (B to C level) for an attention target area (or an attention target that may exist in the attention target area) where the driver is likely to receive attention. ) Is set, and a high warning rank (A to B level) is set for an attention target region (or an attention target that may be present in the attention target region) that is less likely to receive attention. The setting example of the warning rank in FIG. 3 will be specifically described as follows.

(When turning left)
The attention target area S1 can be confirmed when the attention target area S2 is visually recognized, but is set to the B level on the assumption that attention to the vicinity of the host vehicle may not be received. The attention target area S2 is set to the C level because it is considered that the traveling lane is different from the own vehicle and the possibility of contact with the traveling vehicle is low.

  The attention target area S3 is set to the B level because a collision due to a misunderstanding of the other party is assumed when turning right, and the driver is easily prioritized and the driver is easily out of luck. The attention target area S4 is set to the C level because it is considered that the driver is likely to receive attention as the attention target.

  In consideration of the involvement of the motorcycle during a left turn, the attention target area may be expanded to the rear of the vehicle.

(When turning right)
Since the driver's attention may be biased to the right side, the attention target area S1 is set to the A level, the attention target area S2 is set to the B level, and the attention target areas S3 and S4 are set to the C level.

(When going straight)
It is thought that the driver's tension is high and attention is paid over a wide range. However, since it is assumed that there is a high possibility that the attention in the vicinity of the vehicle is distracted, the attention target areas S1 and S4 are set to the B level. The attention target area S3 is set to the B level because a collision due to a recognition error of the other party is assumed when turning right, and the vehicle is prioritized and the driver is easily out of luck. The attention target area S2 is set to the C level because it is considered that the driver is likely to receive attention for a traveling vehicle from the left side.

  The history data accumulating unit 52 recognizes the number of times the driver forgets to visually recognize the attention object existing in each attention object area when each driver took driving action in the past at a branch point, a junction point, or an intersection of the road. History data indicating the completion time is accumulated.

  FIG. 4 shows history data for each driver (P, Q, R). The visual completion time shown in the figure is visual recognition completion time (shortest value, average value, etc.) when the driver takes the driving action at the time of left turn, right turn, or straight ahead. As for this history data, it is desirable to accumulate history for each branch point, junction point, and intersection of the road for each driver.

  In addition, when updating this history data, if it is the first branch point, junction point, or intersection that passes through, it is considered that there is a higher possibility of receiving attention than usual driving behavior, so it will pass again after the next time. It is good to update when you do. Further, since it is considered that the driver's attention is different depending on the time zone such as morning, noon, and night, the history data for each time zone may be accumulated.

  The history data storage unit 52 inputs personal information from the personal authentication device 3 to specify a driver, extracts history data of the specified driver, and outputs it to the determination condition setting unit 55. In addition, the history data storage unit 52 outputs information on the visual recognition completion time for each driver (by individual) to the visual recognition determination unit 51, and inputs the latest visual recognition completion time to update and accumulate the historical data.

The determination condition setting unit 55 sets a visual recognition completion determination condition and a warning rank for determining that the driver of the own vehicle has visually recognized the attention object existing in the attention object area from at least one of the standard data and the history data. Then, the visual recognition completion determination condition and the warning rank are output to the visual recognition determination unit 51. More specifically, when the history data corresponding to the driver authenticated by the personal authentication device 3 is not stored in the history data storage unit 52, when turning left or right in the standard data input from the standard data storage unit 54 In addition to setting the standard visual recognition completion time for each time and straight traveling as the visual recognition completion condition, it is set to generate a warning according to the warning rank for each of the attention target areas S1 to S4.

On the other hand, when history data corresponding to the driver authenticated by the personal authentication device 3 is stored in the history data storage unit 52, the standard data and the history data are compared, and a warning giving priority to the trend of the history data is given. to set the rank.

  For example, if the warning rank at the time of the left turn of the attention target area S2 in the standard data is a low level (C level), but the number of times of forgetting to visually recognize the attention object corresponding to the attention target area S2 in the history data is large, Set the rank to a high level (A to B level).

  Further, when the warning rank at the time of right turn of the attention target area S1 in the standard data is a high level (A level), the number of times of forgetting to visually recognize the attention target corresponding to the attention target area S1 in the history data is small. The rank is set to a low level (B to C level). As described above, the attention target area having a larger number of times of forgetting to visually recognize can increase the effect of preventing forgetting to see by increasing the priority in generating the warning.

  The visual recognition determination unit 51 determines whether the driver's visual behavior satisfies the visual recognition completion determination condition set by the determination condition setting unit 55 for the guidance point when the vehicle approaches the guidance point of the guidance route. To do. When it is determined that the visual recognition completion determination condition is not satisfied, the warning device control unit 56 is configured to generate a warning corresponding to the warning rank corresponding to the attention target area where the attention target that is not visually recognized exists. Output warning information.

  Further, when the visual recognition determination unit 51 satisfies the visual recognition completion determination condition, the visual recognition determination unit 51 outputs information on the visual recognition history to the determination condition setting unit 55. The determination condition setting unit 55 outputs the visual history information to the historical data storage unit 52, and the historical data storage unit 52 updates the historical data using the input visual history information.

  The visual recognition determination unit 51 inputs a driver's driving operation signal (various operation signals such as an accelerator pedal operation, a brake pedal operation, a steering operation, and a turn signal operation), and the driver starts a deceleration operation or decelerates. It is also determined whether or not a start operation for starting again after starting the vehicle is started.

  The warning device control unit 56 inputs warning information from the visual recognition determination unit 51 and performs control to generate a warning corresponding to the warning rank from the display device 6 and the audio output device 7. For example, when the warning rank is a high warning rank (A level) higher than a predetermined level, a warning for forcibly moving the driver's line-of-sight direction to the direction in which the attention object exists is generated. When the warning rank is a low warning rank (B to C level) that is less than a predetermined level, a warning for guiding the driver's line-of-sight direction to the direction in which the attention object exists is generated.

  As a result, when the warning rank is high, a warning for forcibly moving the driver's line-of-sight direction is generated, so the driver forgets to see the attention object in the attention object area with a high warning rank. Will be able to prevent. Further, when the warning rank is low, a warning for guiding the driver's line-of-sight direction is generated. Therefore, the driver's line-of-sight can be guided to the attention object existing in the attention object area having a low warning rank. It becomes possible.

  The warning device control unit 56 uses, for example, visual information by the display device 6 (visual region display by a windshield display, etc.) and auditory information by the audio output device 7 (a human sound source determination mechanism is used to determine the difference in sound volume, sound By controlling the time difference, phase difference, frequency characteristics, and the like of the propagation of sound, it is possible to employ a method that makes it feel as if sound is coming out from the region where the line of sight is to be guided.

  Next, operation | movement by the information provision apparatus for vehicles is demonstrated using the flowchart shown in FIGS. In the following description, the operation when the route guidance function is executed in the navigation device 4 and the vehicle is approaching an intersection where no traffic signal is installed will be described as an example.

  First, in step S10 shown in FIG. 5, navigation information is acquired. In step S20, it is determined whether or not the vehicle has reached an intersection with no signal. If an affirmative determination is made in step S20, the process proceeds to step S30. If a negative determination is made, the process proceeds to step S10, and the above-described process is repeated.

  In step S30, it is determined whether or not there is guidance information for an intersection without a signal that the vehicle has reached. If an affirmative determination is made in step S30, the process proceeds to step S40. If a negative determination is made, the process proceeds to step S10, and the above-described process is repeated.

  In step S40, it is determined whether or not the vehicle has started to decelerate due to the driver starting the deceleration operation. If an affirmative determination is made in step S40, the process proceeds to step S50. If a negative determination is made, the process proceeds to step S60. In the process of step S40, it is determined whether the distance from the own vehicle to the intersection where there is no signal is equal to or less than a predetermined distance. When the distance is equal to or less than the predetermined distance, the process proceeds to step S50 and exceeds the predetermined distance. Alternatively, the process may proceed to step S60.

  In step S60, it is determined whether or not the vehicle has passed an intersection with no signal. If an affirmative determination is made in step S60, the process proceeds to step S10, and the above-described process is repeated. On the other hand, if a negative determination is made, the process proceeds to step S40.

  In step S50, the measurement of the visual recognition time for each of the attention target areas S1 to S4 at the intersection where the host vehicle is approaching is started. In step S70, it is determined whether or not to turn right at an intersection without a signal. If an affirmative determination is made in step S70, the standard data for the right turn is set as the visual recognition completion determination condition in step S80.

  If a negative determination is made in step S70, it is determined whether a left turn is made at an intersection without a signal in step S90. If an affirmative determination is made in step S90, the standard data at the time of left turn is set as a visual recognition completion determination condition in step S100. Set the completion judgment condition.

  In step S120 shown in FIG. 6, an attempt is made to read the personal information of the driver. In step S130, it is determined whether there is personal information of the driver. If it is determined in step S130 that there is personal information, the process proceeds to step S140. If it is determined that there is no personal information, the process proceeds to step S180.

  In step S140, it is determined whether there is history data corresponding to an intersection where there is no signal that the host vehicle has arrived. If an affirmative determination is made in step S140, the process proceeds to step S150. If a negative determination is made, the process proceeds to step S180.

In step S150, the driver's history data is compared with the standard data to collate the data trends. In step S160, it is determined whether the data trends match. If the trends match, the process proceeds to step S180. On the other hand, if the trend of the data does not match, at step S170, it sets the warning rank with priority trends of historical data.

  In step S180, line-of-sight information is acquired from the line-of-sight detection device 2, and in step S190a, it is determined whether or not the attention target areas S1 to S4 have been individually confirmed. If an affirmative determination is made in step S190a, the process proceeds to step S190b. If a negative determination is made, the process proceeds to step S220. In step S190b, it is determined whether or not all the attention target areas S1 to S4 have been confirmed. If an affirmative determination is made in step S190b, the process proceeds to step S200. If a negative determination is made, the process proceeds to step S220.

  In step S200, the measurement of the viewing time is finished, and the viewing history that is the driver's viewing behavior result at the intersection without a signal is stored (updated) as history data. In step S210, the number of forgetting to view the history data is subtracted according to the viewing history.

  In step S220, it is determined whether or not the vehicle has started to move forward again because the driver has started the starting operation. If an affirmative determination is made in step S220, the process proceeds to step S230 shown in FIG. 7. If a negative determination is made, the process proceeds to step S190a, and the above-described process is repeated.

  In step S230 shown in FIG. 7, a warning corresponding to the warning rank associated with the attention target area that the driver did not visually recognize is output. In step S240, the number of forgotten viewing of history data is added or subtracted according to the viewing history. That is, the number of forgetting to see is subtracted for the attention target area visually recognized by the driver, and the number of forgetting viewing is added to the attention target area not visually recognized by the driver.

  In step S250, it is determined whether the driver has received a warning and has visually recognized (reconfirmed) the attention object that has not been visually recognized. If an affirmative determination is made in step S250, the process proceeds to step S270. In step S270, the warning output is stopped and the process is terminated. In this way, when the driver visually recognizes the cautionary object that was not visually recognized before the warning output, the warning output is stopped even if the driver visually recognizes the cautionary object by stopping the alarm output. Will not continue.

  On the other hand, if a negative determination is made in step S250, the process proceeds to step S260. Continue to output warnings until the driver reconfirms. In step S260, it is determined whether or not the vehicle has passed an intersection with no signal. If an affirmative determination is made in step S260, the warning output is stopped and the present process is terminated in step S270. On the other hand, if a negative determination is made in step S260, the process proceeds to step S250, and the above-described process is repeatedly executed. As a result, the warning can be continuously output until the driver confirms again.

Thus, vehicle information providing device of the present embodiment will vary depending on the operating behavior of the driver, it is determined whether a warning to the driver is required according to visual completion determination condition corresponding to between CAUTION target area and visual certification completion Therefore, appropriate information can be provided to the driver. In addition, if there is history data when the driver took driving action in the past, the warning rank can be set from this history data, so the characteristics of the visual behavior of each driver should be taken into account in the warning rank Can do it.
