Description

  The present invention relates to an information notification apparatus, an information notification method, a program, and a medium that can construct a more user-friendly system in, for example, a car navigation system mounted on a vehicle.

  In recent vehicles, a car navigation system is often installed to improve user convenience. In such a system, generally, after a user inputs a destination, a route is searched based on the current position of the vehicle, and the route is notified to the user together with map information. When the user drives the vehicle along the route, the user is appropriately notified of guidance information mainly on intersections on the route.

  While the vehicle is traveling along the route, it may be necessary to appropriately notify information other than the guidance information. As a technique corresponding to such a case, there is a technique described in Patent Document 1, for example.

  In Patent Document 1, when displaying a pop-up image including information not related to navigation from a navigation image, the priority set in the displayed navigation image is detected and compared with the priority of the pop-up image. . When the pop-up image has priority over the navigation image, the pop-up image is combined with the navigation image and displayed. When the navigation image has priority, the display of the hop-up image is skipped.

It is a map used in control in one Embodiment of the information notification apparatus 1 of Example 2 which concerns on this invention. 10 is a flowchart illustrating control contents in an embodiment of the information notification apparatus 1 according to the second embodiment.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 1, the information notification device 1 according to the first embodiment includes a control computer 2 (car navigation ECU: Electronic Control Unit) provided in a vehicle. The control computer 2 includes a GPS sensor 3 (Global Positioning System), a yaw rate sensor 4, a steering sensor 5, a receiver 6, a data storage device 7, a display 8, a speaker 9, A watch 10 is connected.

  Furthermore, onboard equipment including other ECUs such as the brake ECU 11 in the vehicle is connected to the control computer 2 according to a communication standard such as CAN (Controller Area Network). In the first embodiment, the in-vehicle device includes a pre-crash safety system, a clearance sonar system, an ETC system, a rear camera image notification system, a hybrid system, an engine ECU, and a hands-free telephone system.

  The brake ECU 11 includes, for example, a CPU, a ROM, a RAM, an EEPROM, a data bus that interconnects them, and an input / output interface, and controls a braking system according to a program stored in the ROM. The brake ECU 11 calculates the vehicle speed from the wheel speed sensor of each wheel, and transmits a data frame including the vehicle speed to the control computer 2 as appropriate.

  The control computer 2 is composed of, for example, a CPU, ROM, RAM, EEPROM, and a data bus and an input / output interface for interconnecting them, and a search means 2a for performing each control described below according to a program stored in the ROM. It functions as a display unit 2b, a determination unit 2c, a notification unit 2d, and a determination unit 2e.

  The GPS sensor 3 receives radio waves from three satellites among a plurality of satellites launched above the earth. Based on these radio waves, the search means 2a of the control computer 2 measures the position of the vehicle, that is, the longitude and latitude based on the principle of triangulation, for example.

  Here, the yaw rate sensor 4 detects the yaw rate of the vehicle, and the steering sensor 5 is provided in a steering device (not shown) of the vehicle to detect the steering angle. The data storage device 7 is composed of a storage medium such as a hard disk, CD-ROM, or DVD-ROM, for example, and becomes a notification target after the map information for display and the map information and information for search are generated in duplicate. It stores and stores related information related to the “post-notification necessity level”, that is, “freshness” of information. The data storage device 7 also constitutes a medium for storing the program according to the present invention.

  The display 8 is also used as a touch panel and functions as an input device for the driver to input a search condition such as a destination and a customization request described later. Based on the destination input by the driver, the search means 2a of the control computer 2 searches for a route to the destination based on the map information for search.

  Furthermore, the receiver 6 is compliant with light or radio beacon, and receives road information from a VICS (Vehicle Information & Communication System).

  The search means 2a of the control computer 2 calculates the moving distance and direction of the vehicle based on the vehicle speed acquired from the brake ECU 11, the yaw rate detected by the yaw rate sensor 4, and the steering angle detected by the steering sensor 5, and The position is measured by an INS (Inertial Navigation System), and the position when the vehicle is located between high-rise buildings or in a tunnel and the GPS sensor 3 cannot receive radio waves from the satellite is complemented.

  Then, the display means 2b of the control computer 2 includes map information for display in the data storage device 7, the position of the vehicle measured by the method described above, the destination input by the touch panel, that is, the display 8, and the search means 2a. The information about the route searched for is displayed on the display 8 together with the map information for display.

  The determination means 2c of the control computer 2 determines which one of the information and the other information generated at the same time or close in time series has higher priority. In the first embodiment, when information A and information B are generated simultaneously as shown in the upper part of FIG. 2, when information B is generated after the generation of information A and before notification of information A, as shown in the middle part of FIG. As shown in the lower part of FIG. 2, all cases where information B occurs after the start of notification after the generation of information A until the end of notification are targeted.

  When information A has a higher priority for notification than information B, information A corresponds to “other information” and information B corresponds to “one information”. On the other hand, when information B is higher in priority than information A, information B corresponds to “other information” and information A corresponds to “one information”.

  When the determination unit 2c determines that “other information” has higher priority than “one information”, the notification unit 2d gives priority to “other information” and notifies “first information” first. At the same time, the determination means 2e determines the necessity of post notification of "one information", that is, after notifying "other information" and after the time and distance have elapsed since the occurrence of "one information". The level of necessity of notification, in other words, the level of “freshness” is determined. When the determination unit 2e determines that the need for post notification of “one information” is low, the notification unit 2d does not notify “one information”.

  In the first embodiment, the determination unit 2e determines whether the post notification necessity level is high or low based on related information related to the post notification necessity level included in the data frame of one information. Here, the related information is a map as shown in FIG. 3 and includes a valid remaining time and a valid remaining distance determined in advance based on the type of one information. In the first embodiment, as shown in FIG. 3, one piece of information is classified into four types of major items of “Accident avoidance”, “Violation”, “Failure”, and “Navigation information”, and each of them belongs to the major item. The effective remaining time and the effective remaining distance are defined for each of the information.

  The determination unit 2e obtains the elapsed time T and the travel distance L of the vehicle from the time when one information is generated until the end of notification of other information, and whether or not the elapsed time T exceeds the effective remaining time Tth. Based on whether or not the travel distance L exceeds the effective remaining distance Lth, the level of necessity of the post notification is determined. This means that if the elapsed time T exceeds the effective remaining time Tth, or if the travel distance L exceeds the effective remaining distance Lth, the one information is information that is not worth knowing to the user, The value of notification has already been lost and is based on the knowledge that “freshness” and “notification requirement” are low.

  When a specific time of 2.0 sec, 15.0 sec, 1.0 min, or ∞ is specified for the effective remaining time in the map of FIG. 3, the effective remaining time Tth is set to the specified specific time. Is set. Regarding the remaining effective time in the map of FIG. 3, “until the ETC (card) is inserted”, “until the shift is set to other than the R range”, “until the vehicle stops”, “until the abnormality disappears”, “incoming call In the case where “until the predetermined condition is satisfied” such as “until the end” is set, the time from the occurrence of one information to “when the predetermined condition is satisfied” is set as the effective remaining time Tth Is done.

  This “when a predetermined condition is satisfied” is obtained by calculation using various data frames acquired from the CAN and data frames from the clock 10 by the determination unit 2e. When the notification of other information ends, that is, when the freshness is determined, “when the predetermined condition is not satisfied”, the effective remaining time Tth is set to ∞.

When a specific distance of 100 m, 5.0 km, or ∞ is specified for the effective remaining distance in the map of FIG. 3, the effective remaining distance Lth is set to the specified specific distance. If the effective remaining distance in the map of FIG. 3 is defined as “until the obstacle is gone” or “until the signal is passed” or the like “until a predetermined condition is met”, one information is generated. The travel distance from the vehicle position to the vehicle position when a predetermined condition is satisfied is set as the effective remaining distance Lth .

  This “when a predetermined condition is satisfied” is obtained by calculation using various data frames acquired from the CAN on the determination unit 2e and data frames from the clock 10, and the position is appropriately acquired from the search unit 2a. It shall be. Note that the effective remaining distance Lth is set to ∞ at the end of notification of other information, that is, when “predetermined conditions are not satisfied” at the time of determination. In the first embodiment, the setting process of the effective remaining time Tth and the effective remaining distance Lth described above is performed by the determination unit 2e. However, a setting unit may be provided as an individual control entity.

  The setting process described above shows a case where the setting process is performed in real time while the vehicle is running. However, for this setting process, for items other than those belonging to the major item “failure”, for example, an average value of the actual value of “time or distance until a predetermined condition is satisfied” is obtained in advance from the acquired data in the past travel. It may be set appropriately before traveling. When setting before traveling, the effective remaining time Tth and the effective remaining time Tth are both set to average values that are finite values without considering the case where “the predetermined condition is not satisfied”.

  Note that the “pri-crash safety approach warning”, which is the highest priority item in FIG. 3, always has a higher priority than other items, and therefore other items are subject to subsequent notification. It's never "one piece of information." However, this item includes two warnings for the “forward” and “rear” of the vehicle. Among these, the priority of the warning for “forward” is high, An alarm can be “one piece of information” that is subject to post notification. In addition to this, when the alarm for “side” is further included, the priority of “side” is the lowest in this item.

  The control content of the information notification apparatus 1 of the first embodiment described above will be described with reference to the flowchart shown in FIG.

  As shown in step S1 of FIG. 4, the first information A is generated, the generation of this information A is detected by the judging means 2c of the control computer 2, and the second information B is generated in step S2. The determination means 2c detects the occurrence of this information B.

  In step S3, the determination unit 2c determines whether or not the information A has a higher priority than the information B using the map shown in FIG. More specifically, if the priority number in the item of information A in the map shown in FIG. 3 is smaller than the priority number in information B, the determination is affirmative.

  For example, if “hands-free incoming notification” in the large item “navigation information” in the map of FIG. 3 is information A and “navigation general notification” is information B, the priority number of information A is 33. Since the priority number of the information B is 36, the information A has a higher priority than the information B, and in step 3, it is determined as affirmative. In this case, the information A corresponds to “other information”, and the information B corresponds to “one information”.

  Also, if the “navigation general notification” in the large item “navigation information” in the map of FIG. 3 is information A and the “pre-crash safety approach information” in the large item “accident avoidance” is information B, the information Since the priority number of A is 36 and the priority number of information B is 1, information A has a lower priority than information B. In step 3, it is determined to be negative. In this case, the information B corresponds to “other information”, and the information A corresponds to “one information”. If it is determined affirmative in step S3, the process proceeds to step S4. If it is determined negative, the process proceeds to step S10.

  In step S4, the notification unit 2d stores the information B in the stack of the data storage device 7. In step S5, the notification unit 2d sends the notification of the information A to the display 8 and the speaker 9 under the control of the display unit 2b. To do.

  In step S6, the determination unit 2e determines whether or not the notification of the information A by the notification unit 2d has ended. If the determination is affirmative, the process proceeds to step S7. If the determination is negative, the determination unit 2e returns to the position before step S5.

  In step S7, the determination unit 2e obtains the elapsed time TB and the travel distance LB from step S2 to step S6. In step S8, the map shows the elapsed time TB and the travel distance LB using the map shown in FIG. Based on the reference to the related information for each item, it is determined whether TB> Tth or LB> Lth and the freshness of the information B is low. For example, as described above, if “hands-free incoming notification” is information A and “navigation general notification” is information B, information B corresponds to “one information” and the effective remaining time Tth is 1.0 min. The effective remaining distance Lth is set to 5.0 km.

  In step S8, when it is determined that the freshness of the information B is low and the determination is affirmative, it is assumed that the value to be notified to the user has already been lost, the processing in step S9 is skipped, and the process proceeds to END. 2d does not notify. In Step S8, when it is determined negative and it is determined that the freshness is high, the process proceeds to Step S9, and the notification unit 2d notifies the information B.

  In step S10, the notification unit 2d stores the information A in the stack of the data storage device 7. In step S11, the notification unit 2d sends the notification of the information B to the display 8 and the speaker 9 under the control of the display unit 2b. To do.

  In step S11, the determination unit 2e determines whether or not the notification of the information B by the notification unit 2d has ended. If the determination is affirmative, the process proceeds to step S13. If the determination is negative, the determination unit 2e returns to the position before step S11.

  In step S13, the determination unit 2e acquires the elapsed time TA and the travel distance LA from step S1 to step S12. In step S14, the elapsed time TA, the travel distance LA, and the map using the map shown in FIG. Whether TA> Tth or LA> Lth and the freshness of the information A is low is determined based on the reference to the related information for each item. For example, as described above, if the information A is “navigation general notification” and the “pre-crash safety approach information” is information B, the information A corresponds to “one information” and the effective remaining time Tth is 2. At 0 sec, the effective remaining distance Lth is set to ∞.

  In step S14, when it is determined that the freshness is low and the determination is affirmative, it is assumed that it is not worth notifying the user already, the process of step S15 is skipped and the process proceeds to END, and the notification unit 2d does not perform notification. In Step S14, when it is determined negative and it is determined that the freshness is high, the process proceeds to Step S15, and the notification unit 2d notifies the information A.

  The information notification method according to the present invention is executed by sequentially executing the flowchart shown in FIG. 4 described above.

  According to the information notification apparatus 1 of the first embodiment described above and the information notification method executed thereby, the following operational effects can be obtained. That is, when a notification request for two or more pieces of information A and B as shown in FIG. 2 occurs, notification of information with low priority is given after notification of the time required for notification of this information with high priority. It is possible to determine whether or not there is a need to do, that is, “freshness: need for post notification”. Based on this determination, information with low “freshness” can be handled as not being notified.

  In other words, if low priority information to be notified later is not useful information after the time to be notified after the required time has passed, the information shall not be notified as unnecessary information for the driver. It is possible to avoid giving bothersomeness and redundancy. That is, in the first embodiment, a more user-friendly system is constructed for information notification and mediation between information when other information is generated between the generation of information notified to the occupant and the end of notification. Can do.

  In addition, in the first embodiment, since the information A and the information B are displayed on the screen separately, for example, as compared to performing screen division or overlapping display using a hop-up image. Thus, distraction of the user's attention can be prevented.

  For the relevant information in the map shown in FIG. 3 used in the first embodiment, the effective remaining time Tth and the effective remaining distance Lth are set by the determining means 2e or the setting means. Appropriate items can be set in advance by the user.

  In this case, for example, a guidance screen as shown in the left of FIG. 5 is displayed on the display 8 at the timing when the user turns on the ignition key before traveling, and the information notification device 1 of the first embodiment is duplicated in information generation. At this time, the user can be informed that the related information regarding the post notification can be customized and the user can select the customization request.

  When the user touches YES on the display 8 having a touch panel function on the left side of FIG. 5 and selects “Yes”, as shown on the right side of FIG. A display screen on which DOWN can be selected is displayed, and the user can adjust related information. Thereby, user friendliness can be improved further.

  In particular, in the first embodiment, in determining the freshness of information, the elapsed time T and the travel distance L from the generation of information are calculated in real time, and the effective remaining time Tth and the effective distance are increased by increasing the elapsed time T and the travel distance L. It is possible to more accurately evaluate the freshness that changes from high to low in a stepwise manner in the vicinity of the remaining distance Lth, and to make the determination of the freshness level more accurate. As a result, it is possible to realize notification more matched to the user's sense.

  In addition, the effective remaining time Tth and effective remaining time Tth of the map shown in FIG. 3 as a reference for freshness determination are also set appropriately based on the characteristics of each item, and are calculated in real time or past driving By making the measured value based on the above, it is possible to perform a more accurate freshness determination.

  In the above-described first embodiment, all the information handled by the control computer 2 has the related information. However, not all the information needs to have the related information. When information that is not included is included, the following handling can be performed.

  That is, it is determined whether or not the information B has related information before step S4 in the flowchart shown in FIG. 4. If not, the information B stack is not performed without performing the process of step S4. It is possible not to perform storage in the storage, and to determine the freshness determination in step S8 and not to notify the information B in step S9.

  Similarly, it is determined whether or not the information A has related information before step S10 in the flowchart shown in FIG. 4. If the information A does not have the information A, the process of step S10 is not performed. The information is not stored in the stack, and the freshness determination for the information A in step S14 and the notification for the information A in step S15 are not performed.

  In the flowchart shown in FIG. 4, for the convenience of explanation, among the generation forms of information B shown in FIG. 2, from the generation of information A to the notification of information A as shown in the upper part of FIG. 2 and the middle part of FIG. 2. It corresponds to a form in which information B is generated in the meantime. As shown in the lower part of FIG. 2, in the form in which the information B is generated between the notification start of the information A and the notification end, the first half of the notification of the information A is inserted between the steps S1 and S2. Become.

  Here, in particular, when information B has a higher priority than information A, the first half of information A is notified in the inserted step, information B is notified in step S12, and information A in step S15. The latter half of the notification is executed only when it is determined in step S14 that the freshness of the information A is high. For example, the “navigation general notification” shown in FIG. 3 is information A, and the “hands-free incoming notification” is information B.

Thus, after notifying the information A once started to be notified by interrupting the information B having a higher priority, the remaining portion of the information A, that is, the latter half, is notified. If the freshness is low and it is not worth notifying, the notification may not be performed. This allows more effectively prevent the user feels uncomfortable.

  In the above-described first embodiment, related information related to “freshness” and “post-notification necessity” in the map illustrated in FIG. 3 is learned in real time or in advance by the determination unit 2e or the setting unit. As a simpler method, the level of “freshness” may be defined in advance as a fixed value for each item, and freshness determination may be performed using this fixed value. The second embodiment will be described below.

  Since the hardware configuration of the information notification device 1 according to the second embodiment is the same as that shown in the first embodiment, a duplicate description is omitted. The information notification apparatus 1 according to the second embodiment stores a map shown in FIG. 6 in the data storage device 7 in advance instead of the map shown in FIG. That is, the related information shown in FIG. 6 includes the level of freshness that is predetermined based on the type and nature of one information, that is, necessity. In the map of FIG. 6, the high freshness is “H”, and the low is “L”. Note that the numerical values related to the priorities of the items in FIG. 6 are the same as those shown in FIG.

That is, in the second embodiment, determination unit 2e of the control computer 2, the information A or information B, based on whether or not the freshness is a fixed value lower by "L", the item of the map shown in FIG. 6 Judgment.

  The control content of the information notification apparatus 1 of the second embodiment described above will be described with reference to the flowchart shown in FIG.

  As shown in step S1 of FIG. 7, the first information A is generated, the generation of this information A is detected by the judging means 2c of the control computer 2, and the second information B is generated in step S2. The determination means 2c detects the occurrence of this information B.

  In step S3, the determination means 2c determines whether or not the information A has a higher priority than the information B using the map shown in FIG. 6. If the determination is affirmative, the process proceeds to step S4. If so, the process proceeds to step S10.

  In step S4, the notification unit 2d stores the information B in the stack of the data storage device 7, and in step S5, the notification unit 2d performs notification of the information A using the display 8 and the speaker 9.

  In step S6, the determination unit 2e determines whether or not the notification of the information A by the notification unit 2d has ended. If the determination is affirmative, the process proceeds to step S8-1. If the determination is negative, the determination unit 2e returns to the position before step S5. .

  In step S8-1, the determination unit 2e uses the map shown in FIG. 6 and the freshness of the information B is L based on the reference to the item to which the information B belongs and the related information for each item in the map. Determine whether it is low. If it is determined that the freshness is low, it is determined that the notification to the user is unnecessary, the process of step S9 is skipped and the process proceeds to END, and the notification unit 2d does not notify the information B. If it is determined in step S8-1 that the freshness is high, the process proceeds to step S9, and the notification unit 2d notifies the information B.

  In step S10, the notification unit 2d stores the information A in the stack of the data storage device 7. In step S11, the notification unit 2d sends the notification of the information B to the display 8 and the speaker 9 under the control of the display unit 2b. To do.

  In step S11, the determination unit 2e determines whether or not the notification of the information B by the notification unit 2d has ended. If the determination is affirmative, the process proceeds to step S14-1. If the determination is negative, the determination unit 2e returns to the position before step S11. .

  In step S14, the determination unit 2e uses the map shown in FIG. 6, and the freshness of the information A is low at “L” based on the reference to the item to which the information A belongs and the related information for each item in the map. It is determined whether or not. If it is determined that the freshness is low, it is considered that the value to be notified to the user has already been lost, the process of step S15 is skipped and the process proceeds to END, and the notification unit 2d does not perform notification. In Step S14-1, when it is determined negative and it is determined that the freshness is high, the process proceeds to Step S15, and the notification unit 2d notifies the information A.

  The information notification method according to the present invention is executed by sequentially executing the flowchart shown in FIG.

  According to the information notification apparatus 1 of the second embodiment and the information notification method executed thereby, the following operational effects can be obtained as in the first embodiment. That is, when a notification request for two or more pieces of information A and B as shown in FIG. 2 is generated, it is necessary to notify low priority information after notifying high priority information, that is, “freshness: The level of “post-notification necessity” can be determined based on the map shown in FIG. 6, and information with low priority with low “freshness” can be handled as not being notified.

  In other words, in the second embodiment, when low priority information to be notified later is not useful information after the timing to be notified after the lapse of the specified time, it is not notified, and the driver is bothered. Giving a sense of redundancy can be prevented with simpler control content. In particular, as shown in the flowchart of FIG. 7, the processing of step S <b> 7 and step S <b> 13 can be omitted compared to that shown in FIG. 4, and steps S <b> 8 and S <b> 14 can be simplified. The processing load on the control computer 2 can be reduced.

  As for the related information in the map shown in FIG. 6 used in the second embodiment, items suitable for customization by the user may be set in advance by the user as in the first embodiment. it can.

  Even in this case, a guidance screen indicating that customization is possible is displayed on the display 8 at the timing when the user turns on the ignition key before traveling, and if the user selects customization desired, customization is appropriate. Items can be displayed, and a display screen on which H and L can be selected can be displayed to allow the user to select related information.

  Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions are made to the above-described embodiments without departing from the scope of the present invention. be able to.

  For example, in the above-described embodiment, the time is measured using the clock 10 independent of the control computer 2, but the clock function in the control computer 2 can also be used. Also, the numerical values and conditions of the priority and freshness shown in FIG. 3 and the specific examples of the priority and freshness shown in FIG. 6 are merely illustrative.

  Further, in the above-described embodiment, notification of low priority information determined to have low freshness is not executed in both display by the display 8 and voice guidance by the speaker 9.
