[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the drawings, the same parts are designated by the same reference numerals and the description thereof will be omitted.

[0010] (First embodiment) An example configuration of a driving assist information presentation device 1 will be described with reference to Fig. 1. The driving assist information presentation device 1 is mounted on a vehicle. As shown in Fig. 1, the driving assist information presentation device 1 includes a sensor group 10, a controller 20, a user input reception unit 13, a storage device 14, a display 11, and a speaker 12. The storage device 14 is, for example, configured from an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and stores a driving database 15. The driving database 15 will be described later.

[0011] The driving assistance information presentation device 1 may be installed in a vehicle with an automatic driving function or in a vehicle without an automatic driving function. The driving assistance information presentation device 1 may also be installed in a vehicle that is capable of switching between automatic driving and manual driving. The automatic driving function may be a driving assistance function that automatically controls only some of the vehicle control functions, such as steering control, braking force control, and driving force control, to assist the driver in driving.

[0012] The sensor group 10 is mounted on a vehicle and is used to acquire various data and information. Examples of vehicle data include speed, acceleration, steering angle, brake oil pressure, and accelerator opening. Sensors that acquire these data include a speed sensor, acceleration sensor, steering angle sensor, gyro sensor, brake oil pressure sensor, and accelerator opening sensor.

[0013] The controller 20 is a general-purpose microcomputer equipped with a CPU (Central Processing Unit), memory, and input / output units. A computer program for functioning as the driving assistance information presentation device 1 is installed in the microcomputer. By executing the computer program, the microcomputer functions as multiple information processing circuits provided in the driving assistance information presentation device 1. Note that here, an example is shown in which the multiple information processing circuits provided in the driving assistance information presentation device 1 are realized by software, but it is of course possible to configure the information processing circuits by providing dedicated hardware for executing each information process described below. Furthermore, the multiple information processing circuits may be configured by individual hardware. The controller 20 includes, as examples of multiple information processing circuits, a vehicle information acquisition unit 21, a driving diagnosis unit 22, a similarity determination unit 23, a driving assistance information generation unit 24, and a driving improvement effect determination unit 25.

[0014] The vehicle information acquisition unit 21 acquires vehicle information according to the driving operation of the driver. As an example, the vehicle information acquisition unit 21 acquires information related to driving operation such as speed, acceleration, and steering angle from the sensor group 10. As other vehicle information, the vehicle information acquisition unit 21 acquires the date and time of driving, the driving route, and the driving time through the system. The vehicle information acquisition unit 21 outputs the acquired information to the driving diagnosis unit 22 and the driving database 15.

[0015] The driving diagnosis unit 22 performs driving diagnosis such as whether abrupt steering has occurred, whether abrupt acceleration / deceleration has occurred, whether the vehicle is speeding, etc., based on the vehicle information (speed, acceleration, steering angle, etc.) acquired from the vehicle information acquisition unit 21. The driving diagnosis unit 22 outputs the driving diagnosis result to the driving database 15.

[0016] The driving database 15 accumulates information regarding the driver's attributes and preferences received by the user input receiving unit 13, vehicle information output from the vehicle information acquisition unit 21, driving diagnosis results by the driving diagnosis unit 22, similarity judgment results by the similarity judgment unit 23, driving assistance information generated by the driving assistance information generation unit 24, and judgment results by the driving improvement effect judgment unit 25.

[0017] The similarity determination unit 23 determines the similarity between the driver information stored in the driving database 15 and a group of other drivers stored in the driving database 15. The similarity determination unit 23 treats a group of drivers whose similarity is equal to or greater than a certain threshold as a group of similar drivers. Well-known methods are used to determine the similarity, and examples include a vector proximity calculation method such as cosine similarity, and a clustering method such as the k-Means method.

[0018] The driving assistance information generation unit 24 generates driving assistance information based on information about the group of drivers evaluated as a similar driver group by the similarity determination unit 23, and outputs the generated driving assistance information to the display 11 or the speaker 12. In this way, the driving assistance information generation unit 24 presents the driving assistance information to the driver. This encourages the driver to improve their driving behavior by imitating driving in accordance with the driving assistance information. The driving improvement effect determination unit 25 determines whether the driver's driving behavior has improved as a result of the output of the driving assistance information generation unit 24. The driving assistance information may be output to a user terminal (e.g., a smartphone).

[0019] The user input accepting unit 13 accepts input of the driver's attributes, preferences, etc. to be used in determining the similarity. An example of the user input accepting unit 13 is a user terminal such as a display used in a navigation device, a microphone, or a smartphone. An example of driver attributes is shown in Table 1. The driver inputs his or her preferences regarding his or her own attributes, the priority of attributes to be taken into consideration, the adaptive update frequency of driving assistance information, etc. The input content accepted by the user input accepting unit 13 is stored in the driving database 15 and is used by the similarity determining unit 23 to calculate the similarity with other drivers that has already been accumulated.

[0020] [Table 1]

[0021] An example of the function of the driving assist information presentation device 1 will be described with reference to the following Figures 2 to 9. However, Figures 2 and 3 are diagrams for explaining a comparison with the driving assist information presentation device 1, and are not diagrams for explaining the function of the driving assist information presentation device 1.

[0022] FIG. 2 is a diagram showing a guided route displayed on the display 11. In FIG. 2, reference numerals 40, 42, and 43 indicate points where caution is required against sudden braking, reference numeral 44 indicates points where caution is required against sudden steering, reference numeral 41 indicates a section where caution is required against speeding, and reference numeral 45 indicates the destination. Reference numeral 30 indicates a display (text display) that calls attention to the driver. Here, it is assumed that the driver is a woman in her twenties, and the guided route in FIG. 2 is a route that this driver has never driven before. A total of five pieces of information, reference numerals 40 to 44, correspond to the driving assistance information in this embodiment.

[0023] As shown in FIG. 2, when driving assistance information is presented using information on the entire group of drivers accumulated in the driving database 15, all possibilities are presented regardless of the driver's driving tendencies, which may be bothersome to the driver. Therefore, it is considered to present driving assistance information based only on the driver's own history. FIG. 3 shows an example of a case where driving assistance information is presented based only on the driver's own history. Two pieces of driving assistance information (reference numerals 40 and 41) are displayed on the display 11 shown in FIG. 3. When driving assistance information is presented based only on the driver's own history as shown in FIG. 3, the information that can be used to support potential points of caution on routes that the driver has not driven before is limited. When driving assistance information is presented based only on information on the entire group of drivers or the driver's own history as shown in FIGS. 2 and 3, the information may be excessive or insufficient.

[0024] Therefore, in this embodiment, driving assistance information is presented using information from a group of drivers with high similarity. This point will be described with reference to FIG. 4. FIG. 4 shows an example of a case where driving assistance information is presented using information from a group of drivers with high similarity. In FIG. 4, three attention points are presented as indicated by reference numerals 40, 41, and 44. By presenting driving assistance information using information from a group of drivers with high similarity in this way, it is possible to present driving assistance information that is adapted to the driver without excess or deficiency, compared to FIGS. 2 and 3. Reference numerals 46 and 47 shown in FIG. 4 are icons that highlight sudden braking points that many women in their twenties, who have similar driving tendencies to the driver, should be careful of. By presenting driving assistance information using information from a group of drivers with high similarity in this way, it is possible to prioritize points that require particular attention.

[0025] As shown in Fig. 5, when a vehicle 50 driven by a driver approaches a point 40 where special caution is required, the driving support information generation unit 24 generates and presents driving support information such as "The next intersection is a point where you need to brake suddenly. Please be careful," as shown by reference numeral 30 (note that the icons shown by reference numerals 40, 41, 44, 46, and 47 are also examples of driving support information). Note that reference numeral 30 in Fig. 5 also has the property of reminding the driver of the caution point.

[0026] After the vehicle 50 passes the caution point 40, the driving improvement effect determination unit 25 determines whether the driver has responded to the caution content. The driving improvement effect determination unit 25 outputs information on whether the response has been achieved or not depending on the determination result. Reference numeral 30 shown in FIG. 6 is an example of an output when the driver has responded to (achieved) the caution content. When the driver actually stops the vehicle 50 without braking suddenly, the output indicates that the response has been achieved by displaying "As expected!" as shown by reference numeral 30. Also, an icon may be displayed to indicate that the driver has achieved the sudden braking, as shown in FIG. 6.

[0027] As shown in FIG. 7, when a vehicle 50 driven by a driver approaches a speeding caution point 41, the driving assistance information generation unit 24 generates and presents driving assistance information such as "The next road is a speeding caution point. Please be careful of the speed limit," as shown by reference numeral 30. After the vehicle 50 passes the caution point 40, the driving improvement effect determination unit 25 determines whether the driver has responded to the caution content. Reference numeral 30 shown in FIG. 8 is an example of output when the driver has not responded to (failed to achieve) the caution content. If the driver exceeds the speed limit, an output is displayed indicating that the speed limit could not be achieved, as shown by reference numeral 30, displaying "Please be careful of the speed limit." Alternatively, an icon may be displayed indicating that the speed limit could not be achieved, as shown in FIG. 8.

[0028] FIG. 9 is an example of driving support information that is output after driving is completed, for reviewing driving. Reference numeral 30 in FIG. 9 is output depending on whether the cautions were met. In the example shown in FIG. 9, the driver was able to comply with the rules for sudden braking and sudden steering, but was unable to comply with the rule for speeding, so as shown by reference numeral 30, "Good job driving! There were no problems with sudden braking or sudden steering. As expected! You exceeded the speed limit, so be careful next time." is output. In this case, driving support information encouraging compliance with the speed limit may be output preferentially from the next time to the driver who did not comply with the rules for speeding and to a group of drivers with high similarity.

[0029] Next, an example of the operation of the driving assist information presentation device 1 will be described with reference to the flowchart of FIG.

[0030] In step S101, the driver inputs information about attributes and preferences to the user input receiving unit 13 before starting driving. The process proceeds to step S103, where the similarity determination unit 23 determines the similarity between the driver's information stored in the driving database 15 and a group of other drivers stored in the driving database 15. An example of the similarity determination method is as described above. The process proceeds to step S105, where the driver sets a driving route. The process proceeds to step S107, where the driving assistance information generation unit 24 generates pre-driving driving assistance information based on the driver's own information stored in the driving database 15 and the information of the group of drivers evaluated as a similar driver group by the similarity determination unit 23, and outputs the generated information to the display 11 or the speaker 12. Examples of "pre-driving driving assistance information" are reference numerals 30, 40 to 41, 44, and 46 to 47 shown in FIG. 4. The process proceeds to steps S109 to S111, where the sensor group 10 acquires various types of vehicle information during driving.

[0031] The process proceeds to step S113, where the driving diagnosis unit 22 performs a driving diagnosis, such as whether the driver made a sudden turn, whether the driver accelerated or decelerated suddenly, or whether the driver exceeded the speed limit, based on the vehicle information (speed, acceleration, steering angle, etc.) acquired from the vehicle information acquisition unit 21. At this time, the similarity determination unit 23 may re-determine the similarity by further taking the driving diagnosis into consideration. The driving assistance information generation unit 24 may also generate driving assistance information again based on the re-determined similarity. As shown in FIG. 5, when the vehicle 50 driven by the driver approaches the caution point 40 (YES in step S115), the driving assistance information generation unit 24 generates and presents driving assistance information such as "The next intersection is a caution point for sudden braking. Please be careful," as indicated by reference numeral 30 (step S117). Reference numeral 30 in FIG. 5 indicates "driving assistance information during driving." Note that if the process in step S115 is NO, the process ends.

[0032] The process proceeds to step S119, where the driving assistance information generation unit 24 generates and presents driving assistance information according to the determination result by the driving improvement effect determination unit 25. For example, as shown in FIG. 6, if the driver stops the vehicle 50 without braking suddenly, the driving assistance information generation unit 24 generates and presents driving assistance information indicating that the driver was able to respond to the warning content. On the other hand, as shown in FIG. 8, if the driver exceeds the speed limit, the driving assistance information generation unit 24 generates and presents driving assistance information indicating that the driver was unable to respond to the warning content. The process proceeds to steps S121 to S123, where, after the driving is completed, the driving assistance information generation unit 24 generates and presents "post-driving driving assistance information." An example of the "post-driving driving assistance information" is reference numeral 30 shown in FIG. 9.

[0033] (Action and effect) As described above, the driving assist information presentation device 1 according to the first embodiment provides the following advantageous effects.

[0034] The driving assist information presentation device 1 includes a sensor (sensor group 10) that acquires vehicle information according to the driving operation of the vehicle by the driver, a storage device 14 in which data on other drivers excluding the driver is stored in advance, and a controller 20. The controller 20 performs a driving diagnosis on the driver's driving operation based on the vehicle information acquired from the sensor. The controller 20 determines a driving similarity based on the vehicle information, the results of the driving diagnosis, and the data on other drivers stored in the storage device 14. The controller 20 presents driving assist information to assist driving based on the determined similarity and the results of the driving diagnosis. The driving assist information is presented based on data on a group of other drivers determined to have a high similarity. The driving assist information presentation device 1 makes it possible to present driving assist information adapted to the driver based on information on a group of drivers whose driving tendencies are similar to that of the driver himself / herself.

[0035] The similarity is determined based on at least one of (a) the driver's age, (b) the driver's gender, (c) the driver's driving history, (d) the type of vehicle owned by the driver, (e) vehicle information acquired by sensors, (f) the results of driving diagnosis, (g) vehicle location information, (h) driving route history, (i) the driver's riding frequency, (j) the time of day the driver rides, and (k) the driver's riding time, or any combination of (a) to (k). This makes it possible to determine an appropriate similarity.

[0036] The driving assist information presentation device 1 further includes a user input receiving unit 13 that allows the driver to input information relating to his or her own attributes and preferences. This allows the driver to adjust the attributes and preferences to be input, thereby improving the accuracy of the presented driving assist information.

[0037] The controller 20 determines whether the driver has improved his / her driving style, and changes the priority used to determine the similarity or the priority used to present driving support information based on the result of the determination of driving improvement. This makes it possible to preferentially present driving support information that has led to driving improvements in other drivers who have similar driving tendencies to the driver himself / herself.

[0038] (Second embodiment) Next, a second embodiment of the present invention will be described with reference to Fig. 11. The second embodiment differs from the first embodiment in that an image resembling a character is presented as driving assistance information. Components that overlap with those in the first embodiment will be referred to by reference numerals and will not be described again. The following description will focus on the differences.

[0039] Reference numeral 60 in FIG. 11 denotes an image imitating a character (hereinafter referred to as a character image 60). A plurality of character images 60 are prepared, including male, female, elderly, and beginner images. The character image 60 is selected based on the attributes of the driver. Specifically, a character image 60 having an appearance representative of a user whose driving tendency is similar to that of the driver is selected. The controller 20 presents, as driving assistance information, a character image 60 having an appearance representative of a user whose driving tendency is similar to that of the driver. By presenting driving assistance information using character actions such as voice and facial expressions, it is possible to improve the driver's sense of familiarity with the driving assistance.

[0040] (Third embodiment) Next, a third embodiment of the present invention will be described with reference to Fig. 12. The third embodiment differs from the first embodiment in that a proposal for a driving assistance function installed in a vehicle is presented as driving assistance information. The same components as those in the first embodiment will be referred to by reference numerals and their description will be omitted. The following description will focus on the differences.

[0041] FIG. 8 in the first embodiment illustrates an example in which the driver exceeded the speed limit and no driving improvement was achieved. In such a case, in the third embodiment, as shown in FIG. 12, the attention point 41 where no driving improvement was achieved is highlighted by a circle as indicated by reference numeral 70, and a suggestion is made, as indicated by reference numeral 30, saying, "Drivers with driving tendencies similar to yours are using a driving assistance function at this point. Why not try using it next time?" In other words, the controller 20 suggests to the driver to use a driving assistance function based on the usage history of the driving assistance function of other drivers determined to be highly similar, or the results of the driving improvement assessment. This makes it possible to effectively use the driving assistance function to assist with the attention point 41 where the driver is weak. An example of a driving assistance function is automatic braking.

[0042] (Fourth embodiment) Next, a fourth embodiment of the present invention will be described with reference to Fig. 13. The fourth embodiment differs from the first embodiment in that the driving assistance information is presented using information on a group of drivers who have a low similarity in a specific attribute determined by the similarity determination unit 23. Configurations that overlap with those of the first embodiment will be referred to by reference numerals and will not be described again. The following description will focus on the differences.

[0043] Reference numeral 30 in Fig. 13 is an example of driving assistance information generated based on data of a group of drivers who are determined to have low similarity in some attributes among a group of drivers who are determined to have high similarity by the similarity determination unit 23. When a driver who is accustomed to passing through a specific point (hard braking point 40 in the example of Fig. 13) frequently brakes suddenly at this point 40 by other drivers who are not accustomed to passing through this point 40, the information shown by reference numeral 30 is presented to the driver. That is, the controller 20 presents driving assistance information based on data of a group of drivers who are determined to have low similarity in some attributes among a group of other drivers who are determined to have high similarity. This makes it possible to make the driver aware of potential points of caution that differ between the driver and other drivers with similar driving tendencies, and to support risk avoidance behavior such as paying attention to surrounding vehicles.

[0044] Each function described in the above embodiments may be implemented by one or more processing circuits. A processing circuit includes a programmed processing device, such as a processor including electrical circuitry. A processing circuit also includes devices, such as application specific integrated circuits (ASICs) or circuit components, arranged to perform the described functions.

[0045] Although the embodiments of the present invention have been described above, the descriptions and drawings that form part of this disclosure should not be understood as limiting the present invention. Various alternative embodiments, examples, and operating techniques will become apparent to those skilled in the art from this disclosure. [Explanation of symbols]
