  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, the vehicle information notification device 10a of the present embodiment includes an EPS system 12, an ECB system 14, a failure history storage unit 16, a driver personal authentication unit 18, an information output control unit 20, and a severity level determination unit 22. , A display 24, and a speaker / buzzer unit 26. The vehicle information notification device 10a of the present embodiment is mounted on a vehicle and is used to notify the driver of information from systems such as the EPS system 12 and the ECB system 14.

  The EPS (electric power steering) system 12 uses an electric motor to assist steering. The ECB (electronically controlled brake) system 14 is configured by electrically connecting a brake pedal and a four-wheel brake of a vehicle, and controls the brakes of each wheel independently in an optimum state. The EPS system 12 and the ECB system 14 output the information to the failure history storage unit 16 when information to be notified to the driver regarding a failure (failure) or the like is generated in each system.

  In addition to the EPS system 12 and the ECB system 14, the vehicle information notification device 10a includes various systems such as an ACC (adaptive cruise control) system and an LKA (lane keep assist) system (not shown). Is connected to the failure history storage unit 16.

  The failure history accumulation unit 16 is authenticated by the driver personal authentication unit 18 with the time when the failure occurred and the information notified to the driver such as a failure output from each system such as the EPS system 12 and the ECB system 14. This is for associating and storing individual drivers and the number of times information is provided about the failure or the like.

The driver personal authentication unit 18 reads the ID card, fingerprint authentication, iris authentication in the pupil, retina authentication, and the shape of the palm and finger blood vessels.
1233822124779_0
This is for authenticating individual drivers by voiceprint authentication, face authentication, handwriting authentication, and the like.

  Based on the history of information related to failures and the like stored in the failure history storage unit 16 and the individual drivers authenticated by the driver personal authentication unit 18, the information output control unit 20 receives information from the EPS system 12 and the ECB system 14. This is for controlling a mode of notifying the driver of information such as the output failure.

  The severity level determination unit 22 measures or estimates the load applied to the driver based on the driver monitor camera, the in-vehicle radar, the map information of the navigation system, the operation state of the in-vehicle switch, and the like, and the EPS system 12 and the ECB system 14 This is for judging the level of severity of failure or the like related to information output from each system.

  Specifically, the display 24 is a liquid crystal display of a multi-display or a car navigation system, and outputs information such as a failure output from each system such as the EPS system 12 and the ECB system 14 by an image. The speaker / buzzer unit 26 is for outputting information such as a failure output from each system such as the EPS system 12 and the ECB system 14 by voice.

  Hereinafter, the overall operation of the vehicle information notification device 10a of the present embodiment will be described. As shown in FIG. 2, the driver personal authentication unit 18 performs personal authentication of the driver and acquires information such as the driver's sex, age, and driving experience (S101). Here, it is assumed that the system A (for example, the EPS system 12) determines the output of the information provision # 1 (first information) (S102). The information output control unit 20 searches in the vehicle whether information other than the system A is provided before ΔT seconds (S103). Here, ΔT seconds can be set to, for example, 50 to 150 msec, in particular 100 msec, as an allowable time of deviation that can be considered as simultaneous with the information provision of the system A.

  Here, when the system B (for example, the ECB system 14) outputs the information provision # 2 (second information) (S104), the information output control unit 20 includes the information provision # 1 and the information provision # 2. From the information attributes, information provision # 1 and information provision # 2 acquire whether or not the information provision # 2 has the “failure information” attribute (whether or not the information is related to the failure) (S105). Further, the information output control unit 20 acquires the “notification rank” attribute from the information attributes of the information provision # 1 and the information provision # 2 (S106).

  As shown in FIG. 4, there are information attributes such as notification rank, behavior expected of the driver, information providing means, and severity transition possibility for each of the systems A to C according to the system availability and failure status. It has been established. In this embodiment, as will be described later, when information provision # 1 and information provision # 2 notified to the driver have a failure information attribute, the driver's ability, the load on the driver, etc. The notification rank is redefined accordingly. However, in the following description, for the sake of simplicity, neither the information provision # 1 nor the information provision # 2 has the failure information attribute, and is the first case where it is non-failure information. (S107).

  As shown in FIG. 3, when at least one notification rank of information provision # 1 and information provision # 2 is equal to or higher than a certain rank (for example, notification rank 3 shown in FIG. 4), the information output control unit 20 performs S113. Execute.

  When the notification ranks of the information provision # 1 and the information provision # 2 are not the same or equivalent (S113), for example, the information provision # 1 prompts the driver to perform a brake operation as shown in FIG. When the information provision # 2 displays instantaneous fuel consumption as shown in FIG. 6, the information output control unit 20 first sets the information provision # 2 having a low notification rank and a low priority as “information arbitration”. For information provision # 1 with high notification rank and high priority, information is output to the multi-display 200, and information with low priority is provided after t seconds (0.5 to 5 seconds later). Information is output to the multi-display 200 for # 2 (S114).

  When the notification ranks of the information provision # 1 and the information provision # 2 are the same or equivalent (S113), the information output control unit 20 determines from the information attributes of the information provision # 1 and the information provision # 2 The attribute regarding the behavior expected of the driver as shown in FIG. 4 is acquired (S115). The information output control unit 20 acquires attributes relating to information providing means as shown in FIG. 4 from the information attributes of the information providing # 1 and the information providing # 2 (S116).

  When the information provision # 1 and the information provision # 2 have the same behavior expected from the driver (S117), and the information provision means of the information provision # 1 and the information provision # 2 are the same (S118), The information output control unit 20 causes the information display # 1 and the information supply # 2 to consolidate the other as “information aggregation” in “information integration”, and causes the multi-display 200 to output information (S119). ).

  For example, when the information provision # 1 is for notifying information related to the EPS system 12 and the information provision # 2 is for notifying a lane departure warning in the LKA system, the behavior expected from the driver is “steering”. Since the information providing means is the multi-display 200, as shown in FIG. 7, the information output control unit 20 aggregates the other into one of information providing # 1 and information providing # 2. Thus, the steering icon 201 and the lane icon 202 related to the steering operation are turned on on the multi-display 200.

  Alternatively, for example, when the information provision # 1 informs information related to the ECB system 14 and the information provision # 2 informs information related to the approach of the vehicle ahead of the ACC system, both are expected from the driver. The action to be performed is related to “braking operation”, and the information providing means is the multi-display 200. Therefore, as shown in FIG. 8, the information output control unit 20 has one of information providing # 1 and information providing # 2. The other vehicle is gathered on one side, and the front vehicle icon 203 that prompts the driver to perform a brake operation on the multi-display 200 is turned on.

  When the information provision # 1 and the information provision # 2 have different behaviors expected from the driver (S117), the information output control unit 20 uses the information provision # 1 and the information provision # 1 as “information integration” in the “information integration”. Information provision # 2 is put together and information is output to multi-display 200 (S120).

  For example, when the information provision # 1 is for notifying a lane departure warning in the LKA system, and the information provision # 2 is for notifying information regarding the approach of the vehicle ahead of the ACC system, the information provision # 1 is a driver. Since the action expected for the vehicle is related to the “steering operation” and the information provision # 2 is related to the “brake operation”, the information output control unit 20 The information provision # 1 and the information provision # 2 are combined together to turn on the steering icon 201 and the lane icon 202 related to the steering operation on the multi-display 200, and the front vehicle icon 203 that prompts the driver to perform the brake operation.

  The information provision # 1 and the information provision # 2 have the same behavior expected from the driver (S117), and the information provision means of the information provision # 1 and the information provision # 2 is, for example, a multi-display 200 and a speaker. / Buzzer unit 26 is different (S118), information output control unit 20 outputs all information provision # 1 and information provision # 2 from multi-display 200 and speaker / buzzer unit 26, respectively (S121).

  Returning to FIG. 2, if at least one of the information provision # 1 and the information provision # 2 has the failure information attribute and is the failure information (S107), the severity level determination unit 22 includes a driver monitor camera, The load applied to the driver is measured or estimated based on the vehicle-mounted radar, the map information of the navigation system, the operation state of the vehicle-mounted switch, and the like (S108).

  The severity level determination unit 22 acquires “severity transition possibility” from the information attribute shown in FIG. 4 for the information provision # 1 and the like (S109). The severity level determination unit 22 manages the information provision # 1 and the like with information attributes, and acquires the number of information provisions that occurred in the past from the information provision history of the failure history stored in the failure history accumulation unit 16 (S110). ). The severity level determination unit 22 determines the original notification rank such as information provision # 1, the driver's ability (static driver characteristics such as the driver's gender and age), and the load on the driver (dynamic driver characteristics). The vehicle is redefined according to the traveling environment of the vehicle, the traveling state of the vehicle, the possibility of severe transition, and the number of past information provisions (S111).

  Hereinafter, details of the operation of providing information to the driver by redefining the severity level as the notification rank will be described. As shown in FIG. 10, the driver personal authentication unit 18 performs personal authentication of the driver and identifies the driver (S201). A failure occurs in the system A (for example, the EPS system 12 here) (S202), and the system B (for example, the ECB in this case) within ΔT seconds (for example, 50 to 150 msec, particularly 100 msec) from the occurrence of the failure of the system A. It is assumed that a failure has occurred in the system 14 (S203, S204).

  In the present embodiment, in the case described above, it is assumed that the severity level of the person with the greater number of failures experienced by the driver has been lowered by the experience, and the failure has occurred with respect to the failure with the smaller number of failure experiences. The driver is notified of the occurrence. As a premise, the content of information notified to the driver is basically switched for each severity level of failure.

  Here, it is assumed that the number of failures of the EPS system 12 that is the system A is NP and the number of failures of the ECB system 14 that is the system B is NC. Also, let NB be the number of occurrences of failure sufficient to implement the following logic. Further, the severity level of each failure is indicated by five levels of numbers 1 to 5, and the larger the number, the more severe the level. When the severity level of each of the system A and the system B is 3 or more, for example, the same 4 (S207) and the number of occurrences of each failure is NB or more (S208), the severity level determination unit 22 ΔN = | NP−NC | is obtained (S209). When the severity level of either system A or system B is less than 3, the information output control unit 20 performs unaddressed notification of information provision # 1 and information provision # 2 unprocessed.

  When the failure occurrence frequency difference N1 is an arbitrary threshold value, 1 ≦ ΔN (= | NP−NC |) ≦ N1, and when the failure occurrence frequency difference between the system A and the system B is small (S210) The severity level determination unit 22 lowers the severity level of the one having the higher number of occurrences of failure by 1 and sets it to 3, for example. When the driver is a woman (S212), the severity level determination unit 22 increases the severity level of failure of each of the system A and the system B by 1 (S213).

  The information output control unit 20 performs the notification of the failure with the smaller occurrence frequency by changing the display mode (display size, display brightness, volume level) according to the severity level (S214). . The information output control unit 20 similarly notifies the failure of the other system within the time T1 seconds + ΔT1 seconds required for the notification of the failure of one system after the notification of the failure of the one system according to the severity level. The display mode is changed (S215). In addition, (DELTA) T1 second can be 0.5-5 second.

  For example, when the occurrence frequency NP of the EPS system 12 is smaller than the occurrence frequency NC of the ECB system 14, the information output control unit 20 indicates the failure of the EPS system 12 to the multi-display 200 as shown in FIG. After the display, the failure of the ECB system 14 is displayed on the multi-display 200 as shown in FIG.

  When N1 <ΔN1 and the difference in the number of occurrences of failure between the system A and the system B is large (S210), the severity level determination unit 22 lowers the severity level of the one with more occurrences of failure by, for example, 2 (S216). Here, when the driver is a woman (S217), the severity level determination unit 22 increases the severity level of failure of each of the system A and the system B by 1 (S218).

  The information output control unit 20 performs notification of the failure with the smaller occurrence frequency by changing the display mode (display size, display brightness, volume level) according to the severity level (S219). . The information output control unit 20 severely reports the failure of the other system within the time T1 seconds + ΔT2 seconds (ΔT2> ΔT1) required for the notification of the failure of one system after the notification of the failure of one system is completed. The display mode is changed according to the level (S220). Note that ΔT2 seconds can be 1 to 10 seconds.

  According to the present embodiment, when the information provision # 1 is generated in the vehicle, the information output control unit 20 searches for whether or not the information provision # 2 is generated in the vehicle, and information in the vehicle When information provision # 2 is generated in the vehicle when provision # 1 is generated, mediation of information for giving priority to either information provision # 1 or information provision # 2 and information provision Since any of the information to be notified in combination with # 1 and information provision # 2 is performed, it is possible to provide more useful information to the driver at that time without causing confusion to the driver.

  Further, according to the present embodiment, the attributes of the information notified to the driver of the vehicle include the behavior expected of the driver, the failure information attribute indicating whether the information is information related to the failure, the information notification rank, and the provision of information. Since the information and the provision history of information are included, it is possible to provide more useful information to the driver at that time without providing confusion to the driver by providing information according to the attribute. Become.

  Further, according to the present embodiment, when the information provision # 1 is generated in the vehicle when the information provision # 1 is generated in the vehicle, the information output control unit 20 performs the information provision # 1 and the information provision # 1. According to the notification rank included in the provision # 2, mediation of information for giving priority to one of the information provision # 1 and the information provision # 2, and the information to be notified together with the information provision # 1 and the information provision # 2 Integration and information provision # 1 and information provision # 2 are either unprocessed to be notified without processing, so that information can be notified in various notification modes according to the information notification rank, and the driver is confused. It is possible to provide more useful information for the driver at that time.

  In addition, according to the present embodiment, when the first information is generated in the vehicle and the second information is generated in the vehicle, the information output control unit 20 performs the information provision # 1 and Since the information correlated with the operation that is highly likely to be used from any one of the information provision # 2 is notified, it is possible to provide more useful information to the driver at that time without causing confusion to the driver. Become.

  Further, according to the present embodiment, the information output control unit 20 is either one of the information provision # 1 and the information provision # 2 according to the behavior expected by the driver included in the information attribute and the information provision means. In order to perform either of the aggregation of information to be reported by consolidating the other and information provision # 1 and the combination of information to be notified together with information provision # 2, the behavior and information expected of the driver Information can be notified in a notification mode suitable for the providing means, and more useful information can be provided to the driver at that time without causing confusion to the driver.

  Further, according to the present embodiment, the severity level determination unit 22 indicates that when the failure information attribute indicates that the information to be provided is information related to the failure, the driver's ability, the load on the driver, By redefining the severity level of the information, based on the characteristics of the vehicle's driving environment, the experience the driver has been provided with, and / or the likelihood of failure severity for the driver, Since the notification rank of information is redefined, more useful information can be provided to the driver at that time.

  Furthermore, according to the present embodiment, when information provision # 1 is generated in the vehicle when information provision # 1 is generated in the vehicle, the notification ranks of information provision # 1 and information provision # 2 are provided. Is either less than a certain threshold value, information provision # 1 and information provision # 2 are unprocessed to be notified unprocessed, so information with a low notification rank is notified unprocessed This makes it possible to reduce the processing load on the apparatus.

  In particular, in the present embodiment, a failure with a large number of information notifications and a lot of experience is likely to be able to be dealt with in an emergency from the experience of the driver. By giving priority to informing the failure with a small amount of failure, it is possible to promptly inform the driver of what the driver should do at that time and what information should be understood.

  Further, in this embodiment, by correcting the severity level according to the difference in muscle strength due to gender differences, it is possible to provide information in consideration of the driver's muscle strength, and appropriate information according to the driver's muscle strength. Provision is possible. That is, in the present embodiment, it is possible to provide appropriate information to the driver by switching the severity level depending on the gender difference and the number of experiences.

  Hereinafter, a second embodiment of the present invention will be described. As shown in FIG. 14, in the vehicle information notification device 10b of the present embodiment, the engine system 15 that controls the engine of the vehicle in addition to the EPS system 12 and the ECB system 14 is added to the information output control unit 20. 16 is different from the first embodiment in that it is directly connected without going through 16. Further, the present embodiment is different from the first embodiment in that an information output control unit 20 is connected to a driving status determination unit 32 for determining the driving status of the vehicle instead of the severity level determination unit 22. ing. The driving situation determination unit 32 includes a navigation system 30 for acquiring road alignment information according to the vehicle position and map information obtained by GPS (Global Positioning System), and various vehicles such as a vehicle speed sensor and a yaw rate sensor. A sensor 34 is connected.

  Hereinafter, the operation of the vehicle information notification device 10b of the present embodiment will be described. As shown in FIG. 15, the driver personal authentication unit 18 performs personal authentication of the driver and identifies the driver (S301). A failure occurs in the system A (for example, the EPS system 12 here) (S302), and the system B (for example, the ECB here) within ΔT seconds (for example, 50 to 150 msec, particularly 100 msec) from the occurrence of the failure of the system A. It is assumed that a failure has occurred in system 14) (S303, S304).

  In the present embodiment, when the same severity level failure occurs at the same time as described above, the driver is notified from the driving situation and the road alignment situation obtained by the navigation system 30 and the various vehicle sensors 34. Toggle information about failure

  When the driver is a woman (S305), the information output control unit 20 increases the severity level of failure of each of the system A and the system B by 1 (S306). When the severity level of failure between the system A and the system B is 4 or more (S307), the information output control unit 20 acquires the traveling state of the vehicle by the driving state determination unit 32 (S308).

  As shown in the case C1 of FIG. 16, when the vehicle is traveling straight (S309), the information output control unit 20 performs an operation of the ECB system 14 of the system B that is more important during linear traveling as shown in FIG. A failure is preferentially notified (S310). On the other hand, as shown in case C2 in FIG. 16, when the vehicle is traveling in a corner (S309), the information output control unit 20 is connected to the system A, which is more important during traveling in the corner as shown in FIG. A failure of the EPS system 12 is preferentially notified (S311).

  In addition, for example, when the system A is the engine system 15 and the system B is the ECB system 14, the failure of the engine system 15 and the failure of the ECB system 14 may occur simultaneously while the vehicle is traveling on a slope. When this occurs, the information output control unit 20 gives priority to the failure of the ECB system 14 of the system B, which is more important during running on a slope, as shown in FIG.

  If the severity level of the failure of either system A or system B is less than 4 (S307), the information output control unit 20 gives priority to reporting the failure of the system with the higher severity level (S312). ).

  According to the present embodiment, by switching information related to the failure to be notified to the driver from the driving situation and the road alignment situation of the driver, the optimum information suitable for the situation where the driver is placed is provided. Therefore, it is possible to prevent a situation where safety is lowered.

  Hereinafter, a third embodiment of the present invention will be described. As shown in FIG. 17, the vehicle information notification device 10 c of this embodiment includes a PSC (Pre-Crash Safety) system 17, an ECB system 14, and an engine system 15 for preventing the collision of the vehicle and reducing the damage of the collision. Are connected to an information integration determination unit 40 that determines whether or not to output information of each system together. In the present embodiment, the PSC system 17 has a function of detecting the driver's face direction with a driver monitor camera or the like, and detects the driver's drowsiness or the like, thereby preventing the collision of the vehicle and reducing the damage caused by the collision. Plan. Connected to the information integration determination unit 40 is an information output integration unit 42 for outputting information of each system together. The information output integration unit 42 is connected to the display 24, the speaker / buzzer unit 26, and an accelerator pedal vibrator 28 for vibrating the accelerator pedal.

  In the present embodiment, when information is provided by the system A and the system B, when the behavior expected by the driver of each system is the same for “stepping on the brake”, “recognizing the situation”, etc., When one system notifies information to the driver, the information notification of the other system can be output earlier than the normal information output timing by ΔT3 seconds. The information provided by the system is integrated and output.

  Further, in the present embodiment, not only the concept of timing such as ΔT seconds but also a system in which the severity level N increases to N + 1 and N + 2 over time when a failure occurs in the system A and the system B. If the severity level is N + M or higher, it is considered possible to output the severity level N + (M + 1) information earlier than usual, and the contents of information provided by each system are integrated. Output. In this embodiment, as shown in FIG. 4, the severity transition possibility (PP = 0 to 100%) is defined in advance for each system, and the severity transition possibility PP is equal to or higher than a certain possibility threshold value PPT. Sometimes, it is a system that causes a failure that progresses in severity.

  Hereinafter, the operation of the vehicle information notification device 10c of the present embodiment will be described. As shown in FIG. 18, when a failure occurs in the system A (S401), the information integration determination unit 40 searches for information provision of driving support systems other than the system A, and ΔT seconds (for example, 50 to 150 msec) from the present time. (Especially 100 msec) before that information can be provided (S402).

  Further, the information integration determination unit 40 provides information related to a failure of the driving support system other than the system A, and searches for a severity level of N + M or more and a severity transition probability PP ≧ PPT ( S403).

  For example, when information provision of the system B is searched as information provision that meets any of the above conditions (S404), the information output integration unit 42 integrates and outputs the information provision contents of each system. In this case, the behavior expected from the driver by providing information between the system A and the system B is the same (S405). For example, an alarm is sounded by the speaker / buzzer unit 26, an image is displayed by the display unit 24, or the like. If the means for providing the information is the same (S406), the information output integration unit 42 cancels the information provision by one system and provides the information only by the information provision of the one system (S407).

  For example, the system A is the PCS system 17, the information provision relates to the PCS rear-end warning, the system B is the ECB system 14, and the information provision notifies the failure of the ECB system 14, In the case where the information provision prompts the driver to perform a brake operation by sounding an alarm by the speaker / buzzer unit 26 or displaying an image by the display unit 24, the information output integration unit 42 displays the display unit 24 for any system. In addition, the speaker / buzzer unit 26 provides information that prompts the driver to operate the brake.

  In the case where the behavior expected from the driver by providing information between the system A and the system B is the same (S405), for example, information such as sounding an alarm by the speaker / buzzer unit 26 or image display by the display unit 24 is displayed. When the means for providing are different (S406), the information output integration unit 42 outputs all information provided by each system by means for providing both pieces of information (S408).

  For example, the system A is the PCS system 17, the information provision is to notify the PCS rear-end collision warning by the alarm by the speaker / buzzer unit 26 and the image display by the display 24, and the system B is the engine system 15. When the information provision is to notify the engine system 15 of a failure by the acceleration of the accelerator pedal by the accelerator pedal vibrator 28, the information output integration unit 42 issues a PCS rear-end warning of the PCS system 17 to the speaker / buzzer unit 26. A failure of the engine system 15 is notified by the acceleration of the accelerator pedal by the accelerator pedal vibrator 28.

  When the behavior expected from the driver by providing information between the system A and the system B is different (S409), the information output integration unit 42 determines the output order according to the priority (severity level) of the information to be output. Then, information is provided for all systems (S409).

  According to the present embodiment, since there is no sense of incongruity that the buzzer, voice guidance, and image display are interrupted in the middle, no break in information provision occurs, and the driver's discomfort with respect to information provision can be reduced. . In addition, according to the present embodiment, since the information can be aggregated and notified to the driver, various distractions of the driver can be prevented, and the behavior expected of the driver can be driven quickly and accurately. Can tell. Furthermore, according to the present embodiment, it is possible to integrate information based on whether the notification of the system information can be output earlier than the normal information output timing or the severity of failure transition. Information that is output from any system of the driving support system and the driver main function (for example, running, turning, stopping, etc.) can be handled, and can be widely applied.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
