Description

[Technical Field]

[0001] The present disclosure relates to a driving evaluation support device. [Background technology]

[0002] There is a demand for technology that allows drivers to drive appropriately. For example, Patent Document 1 discloses a vehicle driving assistance device that detects driving actions performed by the driver while the vehicle is traveling based on the vehicle's state and notifies the driver. The technology disclosed in Patent Document 1 supports the driver's reflection by notifying the driver of driving actions that constitute near misses after the drive. On the other hand, for appropriate driving actions, a notification indicating that appropriate driving actions have been detected is made while the driver is driving, in an attempt to further encourage the driver to perform appropriate driving actions. Furthermore, the technology disclosed in Patent Document 1 supports the driver's reflection by providing notifications, such as an explanation of appropriate driving actions and the effects of appropriate driving actions, after the drive is completed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5303393 Summary of the Invention [Problem to be solved by the invention]

[0004] When instructed to drive appropriately, people instinctively feel resistance. In contrast, the technology disclosed in Patent Document 1 does not notify the driver that a driving behavior that corresponds to a near miss has been detected while driving, but only notifies the driver that an appropriate driving behavior has been detected. This is thought to make the driver less likely to feel resistance and to encourage the driver to drive appropriately. However, the technology disclosed in Patent Document 1 only notifies the driver of the evaluation by the device on the vehicle, and is not sufficiently effective in encouraging appropriate driving behavior.

[0005] One object of this disclosure is to provide a driving evaluation support device that makes it possible to guide a driver to more appropriate driving behavior while minimizing the driver's sense of resistance. [Means for solving the problem]

[0006] The above object is achieved by the combination of features recited in the independent claims, and the subclaims define further advantageous embodiments of the disclosure. The reference numerals in parentheses in the claims correspond to specific means described in the following embodiment as one aspect, and do not limit the technical scope of the present disclosure.

[0007] In order to achieve the above object, the first driving evaluation support device of the present disclosure is a driving evaluation support device used in a vehicle, and includes a vehicle-side evaluation acquisition unit (201) that acquires, via communication, an evaluation score corresponding to the appropriate driving behavior of the vehicle evaluated by an external device (2B, 4, 5) that is a device external to the vehicle, and a vehicle-side display control unit (2021) that causes a display (281A) of the vehicle to display the vehicle's evaluation score based on the vehicle's evaluation score acquired by the vehicle-side evaluation acquisition unit.

[0008] This allows the driver of the vehicle to check a display showing an evaluation score according to the appropriate driving behavior of the vehicle, which is evaluated by a device external to the vehicle. Because this evaluation score is evaluated by a device external to the vehicle, the driver of the vehicle is more likely to have their desire for recognition, that is, to be recognized by others, fulfilled. Furthermore, because the desire for recognition is fulfilled by appropriate driving behavior, the driver of the vehicle is more likely to spontaneously take appropriate driving behavior. As a result, it is possible to guide the driver to more appropriate driving behavior while minimizing the driver's resistance.

[0009] In order to achieve the above object, the second driving evaluation support device of the present disclosure is a driving evaluation support device used in a vehicle, and includes a first driving behavior determination unit (2031) that determines appropriate driving behavior of the vehicle based on at least one of the vehicle behavior, the vehicle operating state, the recognition results of the surrounding environment using sensing results from the vehicle's surrounding monitoring sensor (25), the vehicle occupant state, and input received from the vehicle occupant, a first score calculation unit (2041) that calculates an evaluation score for the vehicle according to the driving behavior determined by the first driving behavior determination unit, and a first evaluation transmission unit (2051) that transmits the vehicle's evaluation score calculated by the first score calculation unit to another vehicle other than the above-mentioned vehicle via communication, and causes a display (281B) of the other vehicle to display the vehicle's evaluation score based on the vehicle's evaluation score.

[0010] According to this, a display showing an evaluation score according to the appropriate driving behavior of the vehicle, as determined by the vehicle itself, can be confirmed by occupants of other vehicles. Therefore, for the driver of the vehicle, the display showing the evaluation score allows others to know about the appropriate driving behavior of the vehicle. Therefore, the driver of the vehicle is more likely to have their desire for recognition, that is, to be recognized by others, fulfilled. Furthermore, because the desire for recognition is fulfilled by appropriate driving behavior, the driver of the vehicle is more likely to spontaneously take appropriate driving behavior. As a result, it is possible to guide the driver to more appropriate driving behavior while minimizing the driver's resistance.

[0011] In order to achieve the above object, the third driving evaluation support device of the present disclosure is a driving evaluation support device used in a vehicle, and includes a second driving behavior judgment unit (2032) that judges the appropriate driving behavior of another vehicle other than the vehicle based on at least one of the recognition results of the surrounding environment using the sensing results of the vehicle's surrounding monitoring sensor (25) and input received from the vehicle's occupants, a second score calculation unit (2042) that calculates an evaluation score for the other vehicle according to the driving behavior judged by the second driving behavior judgment unit, and a second evaluation transmission unit (2052) that causes the evaluation score of the other vehicle calculated by the second score calculation unit to be transmitted to the other vehicle via communication, and causes a display (281B) of the other vehicle to display the evaluation score of the other vehicle based on the evaluation score of the other vehicle.

[0012] This allows the occupants of the other vehicle to see a display showing an evaluation score based on the appropriate driving behavior of the other vehicle, as determined by the vehicle itself. Since this evaluation score is determined by the other vehicle, the driver of the other vehicle is more likely to have their desire for recognition, that is, to be recognized by others, fulfilled. Furthermore, because the desire for recognition is fulfilled by appropriate driving behavior, the driver of the other vehicle is more likely to spontaneously take appropriate driving behavior. As a result, it is possible to guide the driver to more appropriate driving behavior while minimizing driver resistance.

[0013] In order to achieve the above object, the fourth driving evaluation support device of the present disclosure is a driving evaluation support device used in a vehicle, and includes a second driving behavior judgment unit (2032) that judges appropriate driving behavior of another vehicle other than the vehicle based on at least one of the recognition results of the surrounding environment using the sensing results of the vehicle's surrounding monitoring sensor (25) and input received from the vehicle's occupants, a second score calculation unit (2042) that calculates an evaluation score for the other vehicle according to the driving behavior judged by the second driving behavior judgment unit, and a second score determination unit (2062) that determines an evaluation score for the other vehicle from the evaluation score of the other vehicle calculated by the second score calculation unit, and a vehicle-side display control unit (2021) that causes a display (281A) of the vehicle to display the evaluation score of the other vehicle determined by the second score determination unit.

[0014] This allows the occupants of the vehicle to see a display showing an evaluation score based on the appropriate driving behavior of the other vehicle, as determined by the vehicle itself. Since this evaluation score is determined by the other vehicle, the driver of the other vehicle is more likely to have their desire for recognition, that is, to be recognized by others, fulfilled. Furthermore, because the desire for recognition is fulfilled by appropriate driving behavior, the driver of the other vehicle is more likely to spontaneously take appropriate driving behavior. As a result, it is possible to guide the driver to more appropriate driving behavior while minimizing driver resistance.

[0015] In order to achieve the above object, the fifth driving evaluation support device of the present disclosure is a driving evaluation support device as a terminal device external to the vehicle, and includes a third driving behavior judgment unit (404, 503) that judges the appropriate driving behavior of the vehicle based on input received from a user, a third score calculation unit (405, 504) that calculates an evaluation score for the vehicle according to the driving behavior judged by the third driving behavior judgment unit, and a third evaluation transmission unit (406, 505) that transmits the vehicle's evaluation score calculated by the third score calculation unit to the vehicle via communication, and causes the vehicle's display (281) to display the vehicle's evaluation score based on the vehicle's evaluation score.

[0016] This allows the driver of the vehicle to check a display showing an evaluation score corresponding to the appropriate driving behavior of the vehicle, which is evaluated by a terminal device external to the vehicle. Since this evaluation score is determined based on input received from the user on the terminal device external to the vehicle, the driver of the vehicle is more likely to have their desire for recognition, that is, to be recognized by others, fulfilled. Furthermore, because the desire for recognition is fulfilled through appropriate driving behavior, the driver of the vehicle is more likely to spontaneously take appropriate driving behavior. As a result, it is possible to guide the driver to more appropriate driving behavior while minimizing driver resistance.

[0017] In order to achieve the above object, the driving evaluation support device is a terminal device external to the vehicle, and includes an evaluation acquisition unit (4021, 5011) that acquires, via communication, an evaluation score corresponding to the vehicle's appropriate driving behavior, and a terminal-side display control unit (403, 502) that causes a display (281) of the terminal device to display the vehicle's evaluation score based on the vehicle's evaluation score acquired by the evaluation acquisition unit.

[0018] This allows the user of the terminal device to check a display showing an evaluation score corresponding to the appropriate driving behavior of the vehicle. Therefore, for the vehicle driver, the display showing the evaluation score allows others to know about the appropriate driving behavior of the vehicle. Therefore, the vehicle driver's desire for recognition from others is more likely to be satisfied. Furthermore, since the desire for recognition is satisfied through appropriate driving behavior, the vehicle driver is more likely to voluntarily take appropriate driving behavior. As a result, it is possible to guide the driver to more appropriate driving behavior while minimizing the driver's resistance. [Brief explanation of the drawings]

[0020] A number of embodiments for the purpose of disclosure will be described with reference to the drawings. For the sake of convenience, parts having the same functions as parts shown in the drawings used in the previous explanations in the number of embodiments will be given the same reference numerals, and their description may be omitted. For parts given the same reference numerals, the explanations in other embodiments may be referred to.

[0021] (Embodiment 1) <Outline of the driving behavior evaluation system 1> The driving behavior evaluation system 1 is a system for evaluating appropriate driving behavior of a vehicle. As shown in FIG. 1, the driving behavior evaluation system 1 includes a vehicle-side unit 2, a management server 3, a mobile terminal 4, and a non-mobile terminal 5. As shown in FIG. 1, the vehicle-side unit 2 is installed in each of multiple vehicles. When distinguishing between the host vehicle and other vehicles, as shown in FIG. 1, the vehicle-side unit 2 of the host vehicle is referred to as vehicle-side unit 2A, and the vehicle-side unit 2 of the other vehicle is referred to as vehicle-side unit 2B. The other vehicle refers to a vehicle other than the host vehicle. For convenience, FIG. 1 illustrates an example in which the vehicle-side unit 2 is installed in each of two vehicles, but this is not necessarily limited to this. The driving behavior evaluation system 1 may include vehicle-side units 2 installed in each of three or more vehicles. The mobile terminal 4 is carried by a pedestrian. Examples of the mobile terminal 4 include a multi-function mobile phone and a tablet terminal. The non-mobile terminal 5 is placed on a surface such as a desk. The non-portable terminal 5 is a terminal that can be carried around but is mainly used by placing it on a surface such as a desk. Examples of the non-portable terminal 5 include a desktop PC and a notebook PC. Note that a notebook PC may be included in the portable terminal 4, but in this embodiment, the description will continue assuming that the notebook PC is a non-portable terminal 5.

[0022] The vehicle-side unit 2 judges the appropriate driving behavior of the vehicle and other vehicles, and calculates evaluation scores (hereinafter referred to as points) according to the driving behavior. The vehicle-side unit 2 transmits information on the calculated points of the vehicle and other vehicles to the management server 3. The vehicle-side unit 2 acquires information on the points of the vehicle and other vehicles evaluated by an external device of the vehicle. The external device is a device external to the vehicle. Examples of the external device include the vehicle-side unit 2B, a portable terminal 4, and a non-portable terminal 5 mounted on the other vehicle. The vehicle-side unit 2 displays the points of the vehicle and other vehicles. The vehicle-side unit 2 transmits information on videos of appropriate driving behavior of the vehicle and other vehicles captured by the vehicle (hereinafter referred to as recommended scene videos) to the management server 3. Details of the vehicle-side unit 2 will be described later.

[0023] The management server 3 is a server device. The management server 3 transmits information about the recommended scene video to the mobile terminal 4 and the non-mobile terminal 5. The mobile terminal 4 and the non-mobile terminal 5 play the recommended scene video based on the information about the recommended scene video acquired from the management server 3. The mobile terminal 4 and the non-mobile terminal 5 accept inputs evaluating appropriate driving behavior from users who have viewed the recommended scene video. The mobile terminal 4 also accepts inputs evaluating appropriate driving behavior from users as pedestrians who have encountered the appropriate driving behavior of a vehicle. Based on these inputs, the mobile terminal 4 and the non-mobile terminal 5 calculate points for the vehicle featured in the recommended scene video. The mobile terminal 4 and the non-mobile terminal 5 then transmit the calculated point information for the vehicle to the management server 3. Details of the mobile terminal 4 and the non-mobile terminal 5 will be described later. The management server 3 tallies and stores points for each vehicle being evaluated based on the point information transmitted from the vehicle-side unit 2, the mobile terminal 4, and the non-mobile terminal 5 of each vehicle. The management server 3 transmits the stored information on points for each vehicle to the vehicle-side unit 2. The management server 3 may consist of one server device or may consist of multiple server devices. The management server 3 may be a server device at a center or a server device in the cloud. Details of the management server 3 will be described later.

[0024] <General configuration of vehicle-side unit 2> Next, an example of the schematic configuration of the vehicle-side unit 2 will be described with reference to FIG. 2. As described above, the vehicle-side unit 2 shown in FIG. 2 can be used in a vehicle. Although the vehicle using the vehicle-side unit 2 is not necessarily limited to an automobile, the following description will be given taking the case of use in an automobile as an example. As shown in FIG. 2, the vehicle-side unit 2 includes a driving evaluation support device 20, a communication module 21, a locator 22, a map database (hereinafter referred to as map DB) 23, a vehicle state sensor 24, a periphery monitoring sensor 25, an interior camera 26, a user input device 27, an information presentation device 28, and an HCU (Human Machine Interface Control Unit) 29. For example, the driving evaluation support device 20, the communication module 21, the locator 22, the map DB 23, the vehicle state sensor 24, the periphery monitoring sensor 25, and the HCU 29 may be configured to be connected to an in-vehicle LAN (see the LAN in FIG. 1).

[0025] The communication module 21 transmits and receives information to and from a server device external to the vehicle via wireless communication. That is, it performs wide-area communication. The communication module 21 performs wide-area communication with the management server 3.

[0026] Locator 22 includes a GNSS (Global Navigation Satellite System) receiver and an inertial sensor. The GNSS receiver receives positioning signals from multiple positioning satellites. The inertial sensor includes, for example, a gyro sensor and an acceleration sensor. Locator 22 sequentially determines the position of the vehicle (hereinafter referred to as the vehicle position) on which locator 22 is mounted by combining the positioning signals received by the GNSS receiver with the measurement results of the inertial sensor. The vehicle position is represented, for example, by latitude and longitude coordinates. Note that the vehicle position may also be determined using a travel distance calculated from signals sequentially output from a vehicle speed sensor mounted on the vehicle.

[0027] The map DB 23 is a non-volatile memory that stores map data. The map data may be map data used for route guidance in the navigation function, or may be high-precision map data. The high-precision map data is map data with higher precision than the map data used for route guidance in the navigation function. The high-precision map data includes information usable for automated driving, such as three-dimensional road shape information, information on the number of lanes, and information indicating the permitted direction of travel for each lane. The high-precision map data may also include information on node points indicating the positions of both ends of road markings such as lane markings. Note that the locator 22 may be configured to use three-dimensional road shape information and not use a GNSS receiver. For example, the locator 22 may be configured to identify the vehicle's position using three-dimensional road shape information and detection results from the perimeter monitoring sensor 25.

[0028] The communication module 21 may receive map data distributed from an external server device, for example, via wide-area communication, and store the data in the map DB 23. In this case, the map DB 23 may be a volatile memory, and the communication module 21 may successively acquire map data for an area corresponding to the vehicle position.

[0029] The vehicle state sensor 24 is a group of sensors for detecting various states of the vehicle. The vehicle state sensor 24 includes a vehicle speed sensor, a brake sensor, a turn signal switch, etc. The vehicle speed sensor detects the speed of the vehicle. The brake sensor detects whether the brake pedal is depressed. The turn signal switch detects whether the turn signal lamp of the vehicle is turned on. The turn signal will be referred to as a turn signal hereinafter. The vehicle state sensor 24 outputs the detected sensing information to an in-vehicle LAN. Note that the sensing information detected by the vehicle state sensor 24 may be configured to be output to the in-vehicle LAN via an ECU installed in the vehicle.

[0030] The perimeter monitoring sensor 25 monitors the environment around the vehicle. As an example, the perimeter monitoring sensor 25 detects obstacles around the vehicle. Examples of obstacles include moving objects such as pedestrians and other vehicles. Examples of obstacles include objects fallen on the road and stationary objects such as roadside traffic lights. The perimeter monitoring sensor 25 also detects road markings such as lane markings around the vehicle. Examples of road markings include crosswalk markings indicating crosswalks. The perimeter monitoring sensor 25 is, for example, a perimeter monitoring camera that captures an image of a predetermined area around the vehicle, or a search wave sensor that transmits search waves to a predetermined area around the vehicle. Examples of search wave sensors include millimeter-wave radar, sonar, and LiDAR (Light Detection and Ranging / Laser Imaging Detection and Ranging). The predetermined area may be a range that at least partially includes the front, rear, left, and right of the vehicle. For example, the predetermined area may be a range that at least includes the area ahead of the vehicle. The perimeter monitoring camera sequentially captures and outputs the captured images as sensing information. The exploration wave sensor sequentially outputs the scanning results based on the received signals obtained when receiving the waves reflected by an obstacle as sensing information.

[0031] The interior camera 26 captures an image of a predetermined range within the interior of the vehicle. It is preferable that the interior camera 26 captures an image of an area including at least the driver's seat of the vehicle. The interior camera 26 is composed of, for example, a near-infrared light source, a near-infrared camera, and a control unit that controls them. The interior camera 26 uses the near-infrared camera to capture an image of an occupant of the vehicle illuminated with near-infrared light by the near-infrared light source. The image captured by the near-infrared camera is analyzed by the control unit. The control unit analyzes the captured image to detect features such as the occupant's face. The control unit may detect the occupant's facial direction based on the detected features of the occupant's upper body, including the face.

[0032] The user input device 27 accepts input from an occupant of the vehicle. The user input device 27 may be an operation device that accepts operation input from the occupant. The operation device may be a mechanical switch or a touch switch integrated with a display. An example of a mechanical switch is a steering switch provided on the steering wheel. Note that the user input device 27 is not limited to an operation device that accepts operation input, as long as it is a device that accepts input from the occupant. For example, the user input device 27 may be a voice input device that accepts voice command input from the occupant.

[0033] The information presentation device 28 is provided in the vehicle and presents information to the interior of the vehicle. The information presentation device 28 presents information in accordance with instructions from the HCU 29. As shown in FIG. 2 , the information presentation device 28 includes a display 281 and an audio output device 282.

[0034] The display device 281 presents information by displaying it. Examples of the display device 281 that can be used include a meter MID (Multi Information Display), a CID (Center Information Display), and a HUD (Head-Up Display). The meter MID is a display device provided in front of the driver's seat inside the vehicle. As an example, the meter MID may be provided on a meter panel. The CID is a display device located in the center of the vehicle's instrument panel. The HUD is provided on, for example, the instrument panel inside the vehicle. The HUD projects a display image formed by a projector onto a predetermined projection area on the front windshield, which serves as a projection member. The light of the image reflected by the front windshield toward the vehicle interior is perceived by the driver seated in the driver's seat. This allows the driver to view a virtual image of the display image formed in front of the front windshield superimposed on part of the foreground. The HUD may be configured to project a display image onto a combiner provided in front of the driver's seat, instead of the front windshield. The audio output device 282 presents information by outputting audio. An example of the audio output device 282 is a speaker. When describing the subject vehicle and the other vehicle separately, the display 281 of the subject vehicle is represented as display 281A, and the display 281 of the other vehicle is represented as display 281B, as shown in FIG. 2. When describing the subject vehicle and the other vehicle separately, the audio output device 282 of the subject vehicle is represented as audio output device 282A, and the audio output device 282 of the other vehicle is represented as audio output device 282B, as shown in FIG. 2.

[0035] The HCU 29 is mainly composed of a computer including a processor, a volatile memory, a nonvolatile memory, an I / O, and a bus connecting these. The HCU 29 executes various processes related to the interaction between the occupant and the vehicle's system by executing a control program stored in the nonvolatile memory. The HCU 29 causes the information presentation device 28 to present information. The HCU 29 acquires the detection result from the interior camera 26. The HCU 29 identifies the state of the occupant of the vehicle from the detection result from the interior camera 26. For example, the HCU 29 identifies whether the driver is checking left and right from the direction of the driver's face detected by the interior camera 26. The HCU 29 may acquire a captured image from the interior camera 26 and perform processes such as detecting the direction of the occupant's face. The HCU 29 acquires input information received from the occupant via the user input device 27.

[0036] The driving evaluation support device 20 is mainly configured with a computer including, for example, a processor, a volatile memory, a non-volatile memory, an I / O, and a bus connecting these. The driving evaluation support device 20 executes a control program stored in the non-volatile memory to perform processing related to the evaluation of appropriate driving behavior of a vehicle. The configuration of the driving evaluation support device 20 will be described in detail below.

[0037] <Schematic configuration of driving evaluation support device 20> Next, a schematic configuration of the driving evaluation support device 20 will be described with reference to Fig. 3. As shown in Fig. 3, the driving evaluation support device 20 includes, as functional blocks, an external communication unit 201, an HCU communication unit 202, a driving behavior determination unit 203, a score calculation unit 204, an evaluation transmission unit 205, and a score determination unit 206. Note that some or all of the functions executed by the driving evaluation support device 20 may be configured as hardware using one or more ICs or the like. Furthermore, some or all of the functional blocks included in the driving evaluation support device 20 may be realized by a combination of software execution by a processor and hardware components.

[0038] The external communication unit 201 communicates with the management server 3 via the communication module 21. The external communication unit 201 causes the management server 3 to transmit information via the communication module 21. In other words, the external communication unit 201 causes the management server 3 to upload information. The external communication unit 201 causes the management server 3 to acquire information via the communication module 21. In other words, the external communication unit 201 causes the management server 3 to download information.

[0039] The HCU communication unit 202 performs processing for outputting information to the HCU 29 and processing for acquiring information from the HCU 29. The HCU communication unit 202 acquires information such as the state of the occupant identified by the HCU 29. The HCU communication unit 202 acquires information of input received from the occupant by the user input device 27 via the HCU 29. The HCU communication unit 202 includes a presentation processing unit 2021 as a sub-functional block. The presentation processing unit 2021 sends an instruction to the HCU 29 to cause the information presentation device 28 to present information. In other words, the presentation processing unit 2021 indirectly causes the display device 281 to display information via the HCU 29. The presentation processing unit 2021 corresponds to a vehicle-side display control unit. The presentation processing unit 2021 indirectly causes the audio output device 282 to output audio via the HCU 29.

[0040] The driving behavior determination unit 203 determines appropriate driving behavior of the vehicle. Appropriate driving behavior refers to driving behavior that takes into consideration road users other than the vehicle itself. Appropriate driving behavior may include driving behavior that complies with traffic laws and regulations. Examples of appropriate driving behavior include the following: For example, slowing down when entering an intersection, and stopping temporarily when entering an intersection. For example, checking both sides by the driver when entering an intersection. For example, stopping temporarily before a railroad crossing when passing through it. For example, stopping temporarily before a crosswalk when there are people nearby. For example, passing slowly to the side of pedestrians in the rain.

[0041] The driving behavior determination unit 203 includes a host vehicle behavior determination unit 2031 and a other vehicle behavior determination unit 2032 as sub-functional blocks. The host vehicle behavior determination unit 2031 determines the appropriate driving behavior of the host vehicle. The host vehicle behavior determination unit 2031 may determine the appropriate driving behavior of the host vehicle based on at least one of the behavior of the host vehicle, the operating state of the host vehicle, the recognition result of the surrounding environment using the sensing result of the host vehicle's surrounding monitoring sensor 25, the state of the host vehicle occupants, and input received from the host vehicle occupants. The host vehicle behavior determination unit 2031 corresponds to a first driving behavior determination unit.

[0042] The behavior of the host vehicle may be determined by the driving behavior determination unit 203 from the detection results of the vehicle state sensor 24. As an example, the host vehicle's stop, deceleration, slowing down, etc. may be determined from the vehicle speed detected by the vehicle speed sensor. The operating state of the host vehicle may also be determined by the driving behavior determination unit 203 from the detection results of the vehicle state sensor 24. As an example, the host vehicle's braking operation may be determined from the detection results of the brake sensor indicating whether the brake pedal is depressed. The driving behavior determination unit 203 may recognize the surrounding environment using the sensing results of the periphery monitoring sensor 25. The driving behavior determination unit 203 may recognize the positions, shapes, and movement states of objects and signs around the host vehicle using the sensing results of the periphery monitoring sensor 25. The driving behavior determination unit 203 may recognize the surrounding environment by recognizing the host vehicle's position on a map from the host vehicle position and map data. The host vehicle position may be acquired from the locator 22. The map data may be acquired from the map DB 23. For example, based on the recognition results of the surrounding environment, the vehicle may be identified as entering an intersection, approaching a railroad crossing with an open barrier, approaching a crosswalk with people nearby, or a pedestrian passing by on the side in the rain. The "nearby" may be defined as a distance from a crosswalk that is less than a preset value that can be arbitrarily set. The driving behavior determination unit 203 may identify the occupant status of the vehicle from the occupant status acquired by the HCU communication unit 202. For example, the driving behavior determination unit 203 may identify whether the driver checked left and right. The input received from the occupant of the vehicle may be identified from input information received from the occupant by the user input device 27 acquired by the HCU communication unit 202. For example, the input indicating the type of appropriate driving behavior performed by the driver of the vehicle may be identified. This input may be, for example, displayed on the display 281, allowing the driver to select a type corresponding to the appropriate driving behavior performed by the driver. This input may be made by a passenger who visually observes the appropriate driving behavior performed by the driver.

[0043] The host vehicle behavior determination unit 2031 may determine the appropriate driving behavior of the host vehicle, for example, as follows: If the recognition result of the surrounding environment indicates entering an intersection and the behavior of the host vehicle is decelerating or driving slowly, it may be determined that the host vehicle is decelerating when entering the intersection. If the recognition result of the surrounding environment indicates entering an intersection and the operating state of the host vehicle is braking, it may also be determined that the host vehicle is decelerating when entering the intersection. If the recognition result of the surrounding environment indicates entering an intersection and the behavior of the host vehicle is to stop temporarily, it may be determined that the host vehicle is to stop temporarily when entering the intersection. If the recognition result of the surrounding environment indicates entering an intersection and the occupant state is checking left and right, it may be determined that the driver is checking left and right when entering the intersection. If the recognition result of the surrounding environment indicates entering a railroad crossing with an open barrier and the behavior of the host vehicle is to stop temporarily, it may be determined that the host vehicle is to stop temporarily before passing through the railroad crossing. If the recognition result of the surrounding environment indicates entering a pedestrian crossing with people nearby and the behavior of the host vehicle is to stop temporarily, it may be determined that the host vehicle is to stop temporarily before the crosswalk with people nearby. If the recognition result of the surrounding environment indicates that a pedestrian is passing by the side in the rain and the vehicle is moving slowly, it may be determined that the vehicle is passing by the side of a pedestrian in the rain at a slow pace.

[0044] The other vehicle behavior determination unit 2032 determines the appropriate driving behavior of the other vehicle. The other vehicle behavior determination unit 2032 corresponds to a second driving behavior determination unit. The other vehicle behavior determination unit 2032 may determine the appropriate driving behavior of the other vehicle based on at least one of the recognition result of the surrounding environment using the sensing result of the surrounding monitoring sensor 25 of the host vehicle and input received from the occupant of the host vehicle. The appropriate driving behavior of the other vehicle may be determined based on the recognition result of the surrounding environment as follows. A situation such as the other vehicle entering an intersection may be identified from the position of the other vehicle in the recognized surrounding environment. The behavior of the other vehicle, such as stopping temporarily, may be identified from the movement state of the other vehicle in the recognized surrounding environment. Then, the other vehicle behavior determination unit 2032 may determine the appropriate driving behavior of the other vehicle based on these identification results. The appropriate driving behavior of the other vehicle based on input received from the occupant of the host vehicle may be determined in the same manner as the determination of the appropriate driving behavior of the host vehicle. This input may be made, for example, by selecting a type of appropriate driving behavior performed by the other vehicle from a selection screen for types of appropriate driving behavior of the other vehicle displayed on the display 281. This input may be made by the driver or a passenger of the own vehicle who visually observes the appropriate driving behavior performed by the other vehicle.

[0045] The score calculation unit 204 calculates an evaluation score (hereinafter referred to as a point) according to the appropriate driving behavior determined by the driving behavior determination unit 203. The score calculation unit 204 has a host vehicle score calculation unit 2041 and a different vehicle score calculation unit 2042 as sub-functional blocks. The host vehicle score calculation unit 2041 calculates points for the host vehicle according to the appropriate driving behavior of the host vehicle determined by the host vehicle behavior determination unit 2031. The host vehicle score calculation unit 2041 corresponds to a first score calculation unit. The different vehicle score calculation unit 2042 calculates points for the other vehicle according to the appropriate driving behavior of the other vehicle determined by the different vehicle behavior determination unit 2032. The other vehicle score calculation unit 2042 corresponds to a second score calculation unit. The host vehicle score calculation unit 2041 and the other vehicle score calculation unit 2042 only need to calculate one point for one appropriate driving behavior, regardless of the type of appropriate driving behavior. The own vehicle score calculation unit 2041 and the other vehicle score calculation unit 2042 may calculate different numbers of points depending on the type of appropriate driving behavior. For example, a higher point may be calculated for a driving behavior that is desirable but rarely performed. The own vehicle score calculation unit 2041 and the other vehicle score calculation unit 2042 may calculate different points depending on the type of appropriate driving behavior based on a correspondence relationship between the types of driving behavior and points that is associated in advance.

[0046] The evaluation transmission unit 205 causes the points calculated by the score calculation unit 204 to be transmitted to the other vehicle via communication, and causes the display 281B of the other vehicle to display the points based on the points. The evaluation transmission unit 205 causes the points calculated by the score calculation unit 204 to be transmitted from the external communication unit 201 to the management server 3 via the communication module 21. The points transmitted to the management server 3 are tallied by the management server 3 and transmitted to the other vehicle. In other words, the points are transmitted indirectly from the evaluation transmission unit 205 to the other vehicle. The process of displaying the points acquired by the driving evaluation support device 20 of the other vehicle from the management server 3 on the display 281B of the other vehicle will be described in detail later.

[0047] The evaluation transmission unit 205 includes a host vehicle evaluation transmission unit 2051 and an other vehicle evaluation transmission unit 2052 as sub-functional blocks. The host vehicle evaluation transmission unit 2051 transmits the points of the host vehicle calculated by the host vehicle score calculation unit 2041 to the other vehicle via communication, and causes the display 281B of the other vehicle to display the points of the host vehicle based on the points of the host vehicle. The host vehicle evaluation transmission unit 2051 corresponds to a first evaluation transmission unit. The host vehicle evaluation transmission unit 2051 transmits the points calculated by the host vehicle score calculation unit 2041 from the external communication unit 201 to the management server 3 via the communication module 21. The host vehicle evaluation transmission unit 2051 may also transmit a video, which is time-series data of images captured by a perimeter monitoring camera when the host vehicle behavior determination unit 2031 determines that the driving behavior of the host vehicle is appropriate, to the management server 3. This video information will be referred to as evaluation video data hereinafter.

[0048] This allows occupants of other vehicles to see a display showing points determined by the driver's own vehicle according to the appropriate driving behavior of the vehicle. Therefore, the display showing the points allows the driver of the own vehicle to let others know about the appropriate driving behavior of the vehicle. Therefore, the driver of the own vehicle is more likely to have their desire for recognition, that is, to be recognized by others, fulfilled. Furthermore, because the desire for recognition is fulfilled through appropriate driving behavior, the driver of the own vehicle is more likely to spontaneously take appropriate driving behavior. As a result, it is possible to guide the driver to take more appropriate driving behavior while minimizing driver resistance. Note that whether or not to allow the display showing the driver's own points to be displayed on an external device may be selectable according to an input received from the user via user input device 27.

[0049] When transmitting the points of the vehicle to the management server 3, the vehicle evaluation transmission unit 2051 may also transmit the current vehicle position measured by the locator 22 and an identifier for identifying the vehicle. The identifier for identifying the vehicle will be referred to as a vehicle identifier below. As the vehicle identifier, for example, a vehicle ID or a device ID of the communication module 21 of the vehicle may be used. The driving evaluation support device 20 may be configured to sequentially transmit the vehicle position from the communication module 21 to the management server 3 so that the management server 3 can identify the position history of the vehicle.

[0050] The other vehicle evaluation transmission unit 2052 causes the points of the other vehicle calculated by the other vehicle score calculation unit 2042 to be transmitted to the other vehicle via communication, and causes the display 281B of the other vehicle to display the points of the other vehicle based on the points of the other vehicle. The other vehicle evaluation transmission unit 2052 corresponds to a second evaluation transmission unit. The other vehicle evaluation transmission unit 2052 causes the points calculated by the other vehicle score calculation unit 2042 to be transmitted from the external communication unit 201 to the management server 3 via the communication module 21.

[0051] According to this, a display showing points based on the appropriate driving behavior of the other vehicle, as determined by the own vehicle, can be confirmed by the occupants of the other vehicle. Since these points are determined by the other vehicle, the driver of the other vehicle is more likely to have his or her desire for recognition, that is, to be recognized by others, fulfilled. Furthermore, since the desire for recognition is fulfilled by appropriate driving behavior, the driver of the other vehicle is more likely to spontaneously take appropriate driving behavior. As a result, it is possible to guide the driver to more appropriate driving behavior while minimizing the driver's resistance.

[0052] When causing the other vehicle evaluation transmission unit 2052 to transmit the points of the other vehicle to the management server 3, it may also cause the other vehicle evaluation transmission unit 2052 to transmit the position of the other vehicle identified by the own vehicle and the vehicle identifier of the own vehicle. This allows the management server 3 to also identify the other vehicle, distinguishing it from other vehicles, based on the position history. The position of the other vehicle may be identified by the driving evaluation support device 20 from the position of the own vehicle measured by the locator 22 and the relative position of the other vehicle with respect to the own vehicle, recognized using the sensing results of the perimeter monitoring sensor 25. If the vehicle number of the other vehicle can be recognized by image recognition from an image of the other vehicle captured by the perimeter monitoring camera, the other vehicle evaluation transmission unit 2052 may also cause the other vehicle evaluation transmission unit 2052 to transmit the vehicle number of the other vehicle, when causing the other vehicle points to be transmitted to the management server 3. This allows the management server 3 to also identify the other vehicle, distinguishing it from other vehicles, based on the vehicle number.

[0053] The external communication unit 201 acquires, via communication, information on points corresponding to the appropriate driving behavior of the vehicle, which has been evaluated by an external device such as the vehicle-side unit 2B, the mobile terminal 4, or the non-mobile terminal 5. The external communication unit 201 acquires, from the management server 3, via the communication module 21, information on points about the vehicle, which have been uploaded from the external device to the management server 3 and tallied. The points of the vehicle acquired by the external communication unit 201 may be an aggregate of points for the vehicle, which have been evaluated by multiple external devices and have been continuously collected by the management server 3 from the past. The points tallied by the management server will be referred to as an aggregate value hereinafter. The external communication unit 201 corresponds to a vehicle-side evaluation acquisition unit.

[0054] The external communication unit 201 acquires, via communication, points according to the appropriate driving behavior of other vehicles evaluated by external devices such as the vehicle-side unit 2B, the portable terminal 4, and the non-portable terminal 5. The external communication unit 201 acquires, from the management server 3 via the communication module 21, point information about other vehicles that has been uploaded from the external devices to the management server 3 and tallied. The points of other vehicles acquired by the external communication unit 201 may be an aggregate value obtained by tallying up points of other vehicles that have been evaluated by multiple external devices and that have been continuously collected by the management server 3 from the past. When acquiring point information about other vehicles, the external communication unit 201 may also acquire location information of other vehicles managed by the management server 3. This location information of other vehicles may be information about the most recent location from the location history of other vehicles managed by the management server 3.

[0055] The score determination unit 206 determines the points of the vehicle from the points of the vehicle calculated by the score calculation unit 204 and the points of the vehicle acquired by the external communication unit 201. The score determination unit 206 has a host vehicle score determination unit 2061 and an other vehicle score determination unit 2062 as sub-functional blocks. The host vehicle score determination unit 2061 determines the points of the host vehicle from the points of the host vehicle calculated by the host vehicle score calculation unit 2041 and the points of the host vehicle acquired by the external communication unit 201. The points of the host vehicle calculated by the host vehicle score calculation unit 2041 are the points of the host vehicle evaluated by the host vehicle. The points of the host vehicle acquired by the external communication unit 201 are the points of the host vehicle evaluated by an external device other than the host vehicle. The points of the host vehicle acquired by the external communication unit 201 may be the aggregated value described above. For example, the own vehicle score determination unit 2061 may determine, as the score of the own vehicle, the sum of the points of the own vehicle calculated by the own vehicle score calculation unit 2041 and the aggregated value of the points of the own vehicle acquired by the external communication unit 201. The own vehicle score determination unit 2061 corresponds to the first score determination unit.

[0056] It is preferable that the host vehicle score determination unit 2061 determines the points of the host vehicle by weighting the points of the host vehicle acquired by the external communication unit 201 more heavily than the points of the host vehicle calculated by the host vehicle score calculation unit 2041. In other words, it is preferable to increase the value of evaluations from others. This weighting can be performed by multiplying the points of the host vehicle acquired by the external communication unit 201 by a coefficient greater than 1. This weighting can also be performed by multiplying the points of the host vehicle calculated by the host vehicle score calculation unit 2041 by a coefficient less than 1. This makes it possible to determine the points of the host vehicle by weighting the value of points evaluated by sources other than the host vehicle more heavily than the points evaluated by the host vehicle. Therefore, the display of the points of the host vehicle makes it particularly easy to satisfy the driver of the host vehicle's desire for recognition from others.

[0057] The other vehicle score determination unit 2062 determines the points of the other vehicles from the points of the other vehicles calculated by the other vehicle score calculation unit 2042 and the points of the other vehicles acquired by the external communication unit 201. The points of the other vehicles calculated by the other vehicle score calculation unit 2042 are the points of the other vehicles evaluated by the own vehicle. The points of the other vehicles acquired by the external communication unit 201 are the points of the other vehicle evaluated by an external device other than the own vehicle. The points of the other vehicles acquired by the external communication unit 201 may be the aggregated value described above. For example, the other vehicle score determination unit 2062 may determine the points of the other vehicles as the sum of the points of the other vehicles calculated by the other vehicle score calculation unit 2042 and the aggregated value of the points of the other vehicles acquired by the external communication unit 201. The other vehicle score determination unit 2062 corresponds to the second score determination unit.

[0058] The driving evaluation support device 20 may be configured not to include the other vehicle score determination unit 2062. In this case, the points of the other vehicle calculated by the other vehicle score calculation unit 2042 may be temporarily transmitted by the external communication unit 201 to the management server 3. Then, the total value of the other vehicle calculated by the management server 3 may be obtained, and this total value may be used as the points of the other vehicle.

[0059] The presentation processing unit 2021 causes the display 281A of the vehicle to display the points of the vehicle based on the points of the vehicle acquired by the external communication unit 201. This allows the driver of the vehicle to check a display showing the points corresponding to the appropriate driving behavior of the vehicle, as evaluated by an external device of the vehicle. Because these points are evaluated by an external device of the vehicle, the driver of the vehicle is more likely to have their desire for recognition, that is, to be recognized by others, fulfilled. Furthermore, because the desire for recognition is fulfilled by appropriate driving behavior, the driver of the vehicle is more likely to voluntarily take appropriate driving behavior. As a result, it is possible to guide the driver to more appropriate driving behavior while minimizing the driver's resistance.

[0060] The display showing the points of the vehicle is hereinafter referred to as the vehicle point display. The vehicle point display may be a display showing the accumulated points of the vehicle. The accumulated points of the vehicle may be limited to a certain period in the past. The certain period may be set to any period such as one week, one month, one year, etc. The vehicle point display may also be the average value of the vehicle's points per unit period. The unit period may be set to any period such as one day, one week, one month, etc. The vehicle point display may be displayed, for example, on an electronic map together with a mark indicating the vehicle's position. An example of the vehicle point display on an electronic map will be described later.

[0061] The presentation processing unit 2021 may cause the display 281A of the host vehicle to display the host vehicle's points determined by the host vehicle score determination unit 2061. This makes it possible to display the host vehicle's points including the points evaluated by the host vehicle. In addition, it is possible to display the host vehicle's points even when points evaluated by a device other than the host vehicle have not yet been obtained. Note that the driving evaluation support device 20 may not include the host vehicle score determination unit 2061, and may instead cause the display 281A of the host vehicle to display the host vehicle's points indicating the points of the host vehicle acquired by the external communication unit 201.

[0062] The presentation processing unit 2021 may cause the display 281A of the own vehicle to display the points of the other vehicle determined by the other vehicle score determination unit 2062. This allows the occupants of the own vehicle to confirm a display indicating the points determined by the own vehicle according to the appropriate driving behavior of the other vehicle. Since these points are determined by the other vehicle, the driver of the other vehicle is more likely to have his or her desire for recognition from others fulfilled. As a result, it is possible to guide the driver to more appropriate driving behavior while minimizing the driver's resistance. Note that the driving evaluation support device 20 may not include the other vehicle score determination unit 2062, and may cause the display 281A of the own vehicle to display the points of the other vehicle acquired by the external communication unit 201.

[0063] The display showing the points of other vehicles will be referred to as the other vehicle point display below. The other vehicle point display may be a display showing the accumulated points of other vehicles. The accumulated points of other vehicles may be the same as that explained for the accumulated points of the own vehicle. The display showing the points of other vehicles may be displayed, for example, on an electronic map together with a mark indicating the position of the other vehicle. An example of the other vehicle point display on an electronic map will be described later.

[0064] Here, an example of the host vehicle point display and the other vehicle point display will be described with reference to Figs. 4 and 5. Fig. 4 is a diagram for schematically explaining a situation in which the host vehicle judges the appropriate driving behavior of the other vehicle and assigns points to the other vehicle. In Fig. 4, OV indicates the host vehicle, and FV indicates the other vehicle in front. PE in Fig. 4 indicates a pedestrian. The situation shown in Fig. 4 illustrates a case in which the other vehicle FV in front of the host vehicle OV performs appropriate driving behavior by temporarily stopping in front of a crosswalk where a pedestrian PE is nearby. In this situation, the driving evaluation support device 20 of the host vehicle judges the appropriate driving behavior of the other vehicle FV and calculates one point as a point for the other vehicle FV. The calculated one point is then transmitted to the management server 3. In other words, one point is assigned to the other vehicle FV.

[0065] FIG. 5 is a diagram showing an example of the host vehicle point display and the other vehicle point display in the situation of FIG. 4. The OVM in FIG. 5 indicates the host vehicle position of the host vehicle OV in FIG. 4. In FIG. 5, the host vehicle position is represented by a white arrow mark. The FVM in FIG. 5 indicates the position of the other vehicle FV in FIG. 4. In FIG. 5, the positions of the other vehicles are represented by black arrow marks. In FIG. 5, the positions of other vehicles other than the other vehicle FV are also shown. The numerical value next to the host vehicle position OVM in FIG. 5 indicates the host vehicle point display. The numerical value next to the position of the other vehicle in FIG. 5 indicates the other vehicle point display. As shown in FIG. 5, the host vehicle point display and the other vehicle point display are displayed on an electronic map together with the host vehicle position and the positions of the other vehicles. The newly awarded points may be displayed separately from the value obtained by aggregation so that the newly awarded points are easily recognized. For example, as shown in FIG. 5, the newly awarded points may be displayed as +1 next to the value obtained by aggregation.

[0066] Next, an example of the flow of processing related to the evaluation of the driving behavior of the own vehicle and other vehicles (hereinafter referred to as driving behavior evaluation related processing) in the driving evaluation support device 20 will be described using the flowchart of Fig. 6. The flowchart of Fig. 6 may be configured to be started when, for example, a switch (hereinafter referred to as a power switch) for starting the internal combustion engine or motor generator of the own vehicle is turned on. The example of Fig. 6 shows an example in which the own vehicle score determination unit 2061 and the other vehicle score determination unit 2062 are not provided.

[0067] First, in step S1, the driving behavior determination unit 203 acquires the vehicle position from the locator 22. In step S2, the external communication unit 201 acquires point information for the vehicle and other vehicles, and position information for the other vehicles, from the management server 3. It is preferable that the external communication unit 201 transmits the vehicle position acquired in S1 to the management server 3, thereby narrowing down the acquired information to point and position information for other vehicles around the vehicle position. This makes it possible to reduce the acquisition of unnecessary information and reduce the communication load. The area around the vehicle position may be an area less than a specified distance from the vehicle that can be arbitrarily set.

[0068] In step S3, the presentation processing unit 2021 causes the display 281A of the host vehicle to display the positions of the host vehicle and the other vehicle acquired in S2, as well as the host vehicle point display and the other vehicle point display. In Fig. 6, the host vehicle point display and the other vehicle point display are collectively referred to as the host and other vehicle point display.

[0069] The presentation processing unit 2021 may change the color of the display of the points of the subject vehicle and other vehicles depending on the amount of points. For example, the color may change from bronze to silver to gold as the accumulated points increase. The presentation processing unit 2021 may display the points of the subject vehicle and other vehicles in a ranking format. For example, the points of the subject vehicle and other vehicles may be displayed in order according to the amount of points. This ranking may be displayed for different administrative divisions, such as nationwide, prefectures, or municipalities. The administrative divisions to which the subject vehicle and other vehicles belong may be based on information registered in the management server 3. The management server 3 may register the administrative divisions to which the subject vehicle and other vehicles belong based on location history, user input, or vehicle numbers. An incentive may be provided according to the points. For example, a reward that can be used for vehicle insurance premiums may be provided to the user according to the points.

[0070] In step S4, the host vehicle evaluation process is performed, and the process proceeds to step S5. Here, an example of the flow of the host vehicle evaluation process will be described using the flowchart in Fig. 7. First, in step S41, the host vehicle behavior determination unit 2031 determines the appropriate driving behavior of the host vehicle. In step S42, if the host vehicle behavior determination unit 2031 determines that the host vehicle has an appropriate driving behavior (YES in S42), the process proceeds to step S43. On the other hand, if the host vehicle behavior determination unit 2031 does not determine that the host vehicle has an appropriate driving behavior (NO in S42), the process proceeds to step S5.

[0071] In step S43, the host vehicle score calculation unit 2041 calculates points for the host vehicle according to the appropriate driving behavior of the host vehicle determined by the host vehicle behavior determination unit 2031. In step S44, the host vehicle evaluation transmission unit 2051 causes the management server 3 to transmit the points for the host vehicle calculated in S43 and the host vehicle position acquired in S1, and proceeds to step S5.

[0072] Returning to FIG. 6, in step S5, another vehicle evaluation process is performed, and the process proceeds to step S6. Here, an example of the flow of the other vehicle evaluation process will be described using the flowchart in FIG. 8. First, in step S51, the other vehicle behavior determination unit 2032 determines the appropriate driving behavior of the vehicle ahead of the host vehicle. The preceding vehicle may be the vehicle immediately preceding the host vehicle. In step S52, if the other vehicle behavior determination unit 2032 determines that the preceding vehicle has an appropriate driving behavior (YES in S52), the process proceeds to step S53. On the other hand, if the other vehicle behavior determination unit 2032 does not determine that the preceding vehicle has an appropriate driving behavior (NO in S52), the process proceeds to step S6.

[0073] In step S53, the other vehicle score calculation unit 2042 calculates points for the front vehicle according to the appropriate driving behavior of the front vehicle determined by the other vehicle behavior determination unit 2032. In step S54, the other vehicle evaluation transmission unit 2052 causes the management server 3 to transmit the points for the front vehicle calculated in S53 and the position of the front vehicle identified by the driving evaluation support device 20, and the process proceeds to step S6. Note that if the vehicle number of the front vehicle can be recognized by image recognition, the vehicle number of the front vehicle may also be transmitted to the management server 3 in S54. The vehicle number of the front vehicle may be recognized by, for example, the other vehicle behavior determination unit 2032.

[0074] Returning to FIG. 6, in step S6, if it is time to end the driving behavior evaluation-related process (YES in S6), the driving behavior evaluation-related process is ended. Examples of the timing to end the driving behavior evaluation-related process include turning off the power switch. On the other hand, if it is not time to end the driving behavior evaluation-related process (NO in S6), the process returns to S1 and is repeated.

[0075] <General configuration of management server 3> Next, a schematic configuration of the management server 3 will be described with reference to Fig. 9. As shown in Fig. 9, the management server 3 includes a communication unit 31, a management unit 32, and an information storage unit 33 as functional blocks.

[0076] The communication unit 31 communicates with the vehicle-side unit 2, the portable terminal 4, and the non-portable terminal 5 via a communication network. The communication unit 31 acquires information on the point, position, and vehicle identifier of the vehicle-side unit 2 transmitted from the vehicle-side unit 2. Hereinafter, a point evaluated by the vehicle-side unit 2, such as the point of the vehicle, will be referred to as a self-evaluation point. The communication unit 31 acquires information on the point and position of another vehicle that is a vehicle ahead of the vehicle, as viewed from the vehicle-side unit 2, transmitted from the vehicle-side unit 2. Hereinafter, a point evaluated by an external device of the vehicle, such as the point of the other vehicle, will be referred to as an other-vehicle evaluation point. When evaluation video data about the vehicle is transmitted from the vehicle-side unit 2, the communication unit 31 acquires the evaluation video data. When the vehicle-side unit 2 transmits the vehicle number of another vehicle, the communication unit 31 acquires the vehicle number.

[0077] The communication unit 31 acquires information on vehicle points and location transmitted from the mobile terminal 4. These vehicle points correspond to other vehicle evaluation points. As will be described later, the mobile terminal 4 is capable of evaluating appropriate driving behavior for each vehicle and awarding points. When information such as a vehicle number that can identify each vehicle (hereinafter referred to as vehicle identification information) other than the vehicle location is transmitted from the mobile terminal 4, the communication unit 31 acquires this vehicle identification information. The communication unit 31 acquires information on vehicle points and vehicle identification information transmitted from the non-mobile terminal 5. These vehicle points also correspond to other vehicle evaluation points. As will be described later, the non-mobile terminal 5 is capable of evaluating appropriate driving behavior for each vehicle and awarding points in accordance with input from a user who has viewed the evaluation video data.

[0078] The management unit 32 manages points for each vehicle. The management unit 32 tallies the points acquired by the communication unit 31 for each vehicle and stores the points in the information storage unit 33 for each vehicle. If the management unit 32 has acquired evaluation video data through the communication unit 31, the management unit 32 also stores the evaluation video data for each vehicle in the information storage unit 33. The information storage unit 33 may be, for example, a non-volatile memory. The management unit 32 may determine whether the vehicles are the same or not based on the vehicle identifier, vehicle identification information, location history, etc., and may tallie points for each vehicle. The management unit 32 may link the tallied points, which are the totaled points, the location history, the vehicle identifier, the vehicle identification information, and the evaluation video data for each vehicle, and store them in the information storage unit 33. When the configuration described above for increasing the value of evaluations from others is adopted, the totaled values ​​may be stored in the information storage unit 33 while distinguishing between self-evaluation points and other vehicle evaluation points.

[0079] The communication unit 31 transmits the aggregated value for each vehicle and information on the most recent location to the vehicle-side unit 2. The communication unit 31 may read the aggregated value for each vehicle and information on the most recent location from the information storage unit 33. When the communication unit 31 receives a request from the vehicle-side unit 2, it may transmit the aggregated value for each vehicle and information on the most recent location. When the communication unit 31 receives a request from the vehicle-side unit 2 and has acquired the vehicle's position from the vehicle-side unit 2, it may transmit the aggregated value for each vehicle and information on the most recent location, limited to vehicles in the vicinity of the vehicle's position.

[0080] The communication unit 31 transmits information on the location history for each vehicle to the mobile terminal 4. When receiving a request from the mobile terminal 4, the communication unit 31 may transmit the information on the location history for each vehicle. When receiving a request from the mobile terminal 4 and the communication unit 31 has acquired the terminal location from the mobile terminal 4, the communication unit 31 may transmit the information on the location history for each vehicle, limited to vehicles in the vicinity of the terminal location. The communication unit 31 may be configured to transmit, to the mobile terminal 4, aggregated values ​​for each vehicle in addition to the information on the location history for each vehicle. The communication unit 31 may be configured to transmit, to the mobile terminal 4, evaluation video data for each vehicle in addition to the information on the location history for each vehicle. The communication unit 31 may read the information on the aggregated values ​​for each vehicle, the information on the location history, and the evaluation video data from the information storage unit 33.

[0081] The communication unit 31 transmits the evaluation video data and vehicle identification information for each vehicle to the non-portable terminal 5. The communication unit 31 may transmit the evaluation video data and vehicle identification information for each vehicle when a request is received from the non-portable terminal 5. The communication unit 31 may be configured to transmit the aggregated value for each vehicle to the non-portable terminal 5 in addition to the evaluation video data and vehicle identification information for each vehicle. The communication unit 31 may read the information on the aggregated value for each vehicle, the evaluation video data, and the vehicle identification information from the information storage unit 33.

[0082] <General configuration of mobile terminal 4> Next, a schematic configuration of the mobile terminal 4 will be described with reference to Fig. 10. As shown in Fig. 10, the mobile terminal 4 includes a control unit 40, a communication unit 41, a display unit 42, a locator 43, a map DB 44, and a user input unit 45 as functional blocks. Note that some or all of the functions executed by the mobile terminal 4 may be configured as hardware using one or more ICs or the like. Also, some or all of the functional blocks included in the mobile terminal 4 may be realized by a combination of software execution by a processor and hardware components. The mobile terminal 4 also corresponds to a driving evaluation support device.

[0083] The communication unit 41 communicates with the management server 3 via a communication network. The communication unit 41 may communicate with the management server 3 via a mobile phone network. The display unit 42 displays information. The display unit 42 may be a display device having a display screen configured, for example, by a liquid crystal display. The locator 43 includes a GNSS receiver and an inertial sensor. The locator 43 sequentially determines the position of the mobile terminal 4 equipped with the locator 43 (hereinafter referred to as the terminal position) by combining the positioning signal received by the GNSS receiver with the measurement results of the inertial sensor. The terminal position is expressed, for example, in latitude and longitude coordinates. The map DB 44 is a non-volatile memory and stores map data. The map data may be map data used for route guidance in the navigation function. The communication unit 41 may receive map data distributed from an external server device and store the map data in the map DB 44.

[0084] The user input unit 45 accepts input from the user of the mobile terminal 4. The user input unit 45 may be an operation device that accepts operation input from the user. The operation device may be a mechanical switch or a touch switch integrated with the display of the display unit 42. Note that the user input unit 45 is not limited to an operation device that accepts operation input, as long as it is a device that accepts input from the user. For example, it may be a voice input device that accepts voice command input from the user.

[0085] The control unit 40 is mainly configured as a computer including, for example, a processor, a volatile memory, a non-volatile memory, an I / O, and a bus connecting these. The control unit 40 executes a control program stored in the non-volatile memory to perform application processing related to the evaluation of appropriate driving behavior of a vehicle. The control unit 40 includes, as functional blocks, a terminal location identification unit 401, an information acquisition unit 402, a display control unit 403, a driving behavior determination unit 404, a score calculation unit 405, and an evaluation transmission unit 406.

[0086] The terminal position specifying unit 401 specifies the terminal position on the map from the map data acquired from the map DB 44 and the terminal position measured by the locator 43 .

[0087] The information acquisition unit 402 acquires information from the management server 3 via the communication unit 41. That is, it downloads information from the management server 3. The information acquisition unit 402 includes an evaluation acquisition unit 4021 and a video acquisition unit 4022 as sub-functional blocks. The evaluation acquisition unit 4021 acquires information on the aggregated points for vehicles stored in the management server 3 from the management server 3 via the communication unit 41. That is, the evaluation acquisition unit 4021 acquires evaluation scores corresponding to appropriate driving behaviors of the vehicles via communication. The evaluation acquisition unit 4021 may acquire information on the aggregated points for multiple vehicles. When acquiring information on the aggregated points for a vehicle, the information acquisition unit 402 may also acquire information on the location history of the vehicle managed by the management server 3. The video acquisition unit 4022 acquires evaluation video data for the vehicle stored in the management server 3 from the management server 3 via the communication unit 41. That is, the video acquisition unit 4022 acquires information on videos recording appropriate driving behaviors of the vehicle.

[0088] The display control unit 403 causes the display unit 42 to display the points of the vehicle based on the aggregated points for the vehicle acquired by the evaluation acquisition unit 4021. This allows the user of the mobile terminal 4 to check the display showing the points corresponding to the appropriate driving behavior of the vehicle. Therefore, for the vehicle driver, the display showing the points allows others to know about the appropriate driving behavior of the vehicle. Therefore, the vehicle driver's desire for recognition from others is more likely to be satisfied. As a result, it is possible to guide the driver to more appropriate driving behavior while minimizing driver resistance. The display showing the points of the vehicle may be similar to the other vehicle point display performed by the presentation processing unit 2021. As an example, instead of the display showing the vehicle position in FIG. 5, a display showing the terminal position may be performed. In other words, the terminal position, the vehicle position, and the vehicle's points may be displayed on an electronic map. This display is hereinafter referred to as a terminal-surrounding point display.

[0089] The display control unit 403 may display on the display unit 42 a video in which appropriate driving behavior of a vehicle is captured, based on the evaluation video data acquired by the video acquisition unit 4022. The display control unit 403 may display the video for each of the multiple vehicles. The display control unit 403 preferably selects and displays the video for each of the multiple vehicles in accordance with input received by the user input unit 45. The user of the mobile terminal 4 watches the video and, for a vehicle whose appropriate driving behavior is to be evaluated, inputs an evaluation of the driving behavior to the user input unit 45. The input for evaluating the driving behavior may be an input for selecting the type of driving behavior. The display control unit 403 corresponds to a terminal-side display control unit.

[0090] The driving behavior determination unit 404 may determine the appropriate driving behavior of the vehicle based on input received from the user. The input from the user may be received by the user input unit 45. This driving behavior determination unit 404 corresponds to a third driving behavior determination unit. An example of the input from the user is an input from a user who watches a video in which the appropriate driving behavior of a vehicle is recorded, to evaluate the driving behavior of the vehicle whose appropriate driving behavior is to be evaluated, as described above. In this case, the driving behavior determination unit 404 determines the appropriate driving behavior of the vehicle based on the input received from the user who watches the video.

[0091] An example of user input is an input from a pedestrian who actually witnessed the appropriate driving behavior of a vehicle, evaluating the driving behavior of the vehicle whose appropriate driving behavior he or she wishes to evaluate. In this case, the driving behavior determination unit 404 determines the appropriate driving behavior of the vehicle based on the input received from the pedestrian. A pedestrian who actually witnessed the appropriate driving behavior of a vehicle may identify the vehicle to be evaluated from the aforementioned display of points around the terminal and input an evaluation of the driving behavior. The display control unit 403 may also display the vehicle's location history on the display unit 42, making it easier for the pedestrian to identify the vehicle to be evaluated. As an example, the vehicle to be evaluated may be selected by touching the vehicle displayed as points around the terminal. The type of driving behavior may be selected from a list display of driving behavior types.

[0092] The score calculation unit 405 calculates points for the vehicle according to the driving behavior determined by the driving behavior determination unit 404. This score calculation unit 405 corresponds to a third score calculation unit. The score calculation unit 405 may calculate points in the same manner as the other vehicle score calculation unit 2042.

[0093] The evaluation transmission unit 406 causes the points of the vehicle calculated by the score calculation unit 405 to be transmitted to the vehicle via communication, thereby causing the display 281 of the vehicle to display the points of the vehicle based on the points of the vehicle. This evaluation transmission unit 406 corresponds to a third evaluation transmission unit. The evaluation transmission unit 406 causes the points calculated by the score calculation unit 405 to be transmitted from the communication unit 41 to the management server 3. The points transmitted to the management server 3 are tallied by the management server 3 and transmitted to the vehicle. In other words, the points are transmitted to the vehicle indirectly from the evaluation transmission unit 406. When transmitting the points of the vehicle to the management server 3, the evaluation transmission unit 406 may also cause the vehicle identification information linked to the vehicle that was the subject of judgment by the driving behavior judgment unit 404 to be transmitted.

[0094] This allows the driver of the vehicle to check a display showing points according to the appropriate driving behavior of the vehicle, which are evaluated by the mobile terminal 4, which is a terminal device external to the vehicle. These points are determined by the mobile terminal 4 based on input received from the pedestrian, who is the user of the mobile terminal 4, so the driver of the vehicle is more likely to have his or her desire for recognition from others fulfilled. As a result, it becomes possible to guide the driver to more appropriate driving behavior while minimizing the driver's resistance.

[0095] <General Configuration of Non-Portable Terminal 5> Next, a schematic configuration of the non-portable terminal 5 will be described with reference to Fig. 11. As shown in Fig. 11, the non-portable terminal 5 includes a control unit 50, a communication unit 51, a display unit 52, and a user input unit 53 as functional blocks. Note that some or all of the functions executed by the non-portable terminal 5 may be configured as hardware using one or more ICs or the like. Also, some or all of the functional blocks included in the non-portable terminal 5 may be realized by a combination of software execution by a processor and hardware components. The non-portable terminal 5 also corresponds to a driving evaluation support device.

[0096] The communication unit 51 communicates with the management server 3 via a communication network. The communication unit 51 may communicate with the management server 3 via the Internet. The display unit 52 displays information. The display unit 52 may be a display device having a display screen configured, for example, by a liquid crystal display. The user input unit 53 accepts input from the user of the non-portable terminal 5. The user input unit 53 may be an operation device that accepts operation input from the user. The operation device may be a mechanical switch or a touch switch integrated with the display of the display unit 52. Note that the user input unit 53 is not limited to an operation device that accepts operation input, as long as it is a device that accepts input from the user. For example, it may be a voice input device that accepts voice commands input from the user.

[0097] The control unit 50 is mainly configured as a computer including, for example, a processor, a volatile memory, a non-volatile memory, an I / O, and a bus connecting these. The control unit 50 executes a control program stored in the non-volatile memory to perform application processing related to the evaluation of appropriate driving behavior of a vehicle. The control unit 50 includes, as functional blocks, an information acquisition unit 501, a display control unit 502, a driving behavior determination unit 503, a score calculation unit 504, and an evaluation transmission unit 505.

[0098] The information acquisition unit 501 acquires information from the management server 3 via the communication unit 51. That is, it downloads information from the management server 3. The information acquisition unit 501 includes an evaluation acquisition unit 5011 and a video acquisition unit 5012 as sub-functional blocks. The evaluation acquisition unit 5011 acquires information on the aggregated points for vehicles stored in the management server 3 from the management server 3 via the communication unit 51. That is, the evaluation acquisition unit 5011 acquires evaluation scores corresponding to appropriate driving behaviors of the vehicles via communication. The evaluation acquisition unit 5011 may acquire information on the aggregated points for multiple vehicles. The video acquisition unit 5012 acquires evaluation video data for vehicles stored in the management server 3 from the management server 3 via the communication unit 51. That is, the video acquisition unit 5012 acquires information on videos in which appropriate driving behaviors of the vehicles are recorded.

[0099] The display control unit 502 causes the display unit 52 to display the points of the vehicle based on the aggregated points for the vehicle acquired by the evaluation acquisition unit 5011. This allows the user of the non-portable terminal 5 to check the display showing the points corresponding to the appropriate driving behavior of the vehicle. Therefore, for the vehicle driver, the display showing the points allows others to know about the appropriate driving behavior of the vehicle. Therefore, the vehicle driver's desire for recognition from others is more likely to be satisfied. As a result, it is possible to guide the driver to more appropriate driving behavior while minimizing the driver's resistance. The display showing the points of the vehicle may be similar to the display of points of other vehicles performed by the presentation processing unit 2021. As an example, the location of the vehicle and the points of the vehicle may be displayed on an electronic map.

[0100] The display control unit 502 may display a video in which the appropriate driving behavior of the vehicle is captured on the display unit 52 based on the evaluation video data acquired by the video acquisition unit 5012. The display control unit 502 may display the video in the same manner as the display control unit 403 described above. The user of the non-portable terminal 5 watches the video and provides an input to the user input unit 53 to evaluate the driving behavior of the vehicle for which the appropriate driving behavior is to be evaluated. The input to evaluate the driving behavior may be an input to select the type of driving behavior. The display control unit 502 also corresponds to the terminal-side display control unit.

[0101] The driving behavior determination unit 503 may determine the appropriate driving behavior of the vehicle based on input received from the user. The input from the user may be received by the user input unit 53. This driving behavior determination unit 503 also corresponds to the third driving behavior determination unit. An example of the input from the user is an input from a user who watches a video in which the appropriate driving behavior of a vehicle is recorded, to evaluate the driving behavior of the vehicle whose appropriate driving behavior is to be evaluated, as described above. In this case, the driving behavior determination unit 503 determines the appropriate driving behavior of the vehicle based on the input received from the user who watches the video.

[0102] The score calculation unit 504 calculates points for the vehicle according to the driving behavior determined by the driving behavior determination unit 503. This score calculation unit 504 also corresponds to the third score calculation unit. The score calculation unit 504 may calculate points in the same manner as the other vehicle score calculation unit 2042.

[0103] The evaluation transmission unit 505 causes the points of the vehicle calculated by the score calculation unit 504 to be transmitted to the vehicle via communication, thereby causing the display 281 of the vehicle to display the points of the vehicle based on the points of the vehicle. This evaluation transmission unit 505 also corresponds to a third evaluation transmission unit. The evaluation transmission unit 505 causes the points calculated by the score calculation unit 504 to be transmitted from the communication unit 51 to the management server 3. The points transmitted to the management server 3 are tallied by the management server 3 and transmitted to the vehicle. In other words, the points are transmitted to the vehicle indirectly from the evaluation transmission unit 505. When transmitting the points of the vehicle to the management server 3, the evaluation transmission unit 505 may also cause the vehicle identification information linked to the vehicle that was the subject of judgment by the driving behavior judgment unit 503 to be transmitted.

[0104] This allows the driver of the vehicle to check a display showing points according to the appropriate driving behavior of the vehicle, which are evaluated on the non-portable terminal 5, which is a terminal device external to the vehicle. As a result, it becomes possible to guide the driver to more appropriate driving behavior while minimizing the driver's resistance.

[0105] Note that points may also be awarded to a vehicle linked to a user who has made an input to evaluate appropriate driving behavior on a terminal device such as the mobile terminal 4 or non-mobile terminal 5. In other words, points may also be awarded to the user who made the evaluation. Linking a user to their vehicle may be achieved by registering a combination of the device ID of the terminal device and the vehicle's vehicle identification information in the management server 3. As an example, when the evaluation transmission unit 406, ☆ causes the management server 3 to transmit points for the vehicle, it may also transmit the device ID of the terminal device to the management server 3. Then, the management server 3 may add points to the vehicle to which the transmitted device ID and vehicle identification information are linked.

[0106] (Embodiment 2) In the above-described embodiment, the configuration was described in which the presentation processing unit 2021 of the driving evaluation support device 20 causes the display 281A to display the own vehicle point and the other vehicle point, but this is not necessarily limited to this. For example, the display 281A may be configured to display only the own vehicle point out of the own vehicle point display and the other vehicle point display. In this case, the own vehicle point display includes points evaluated by an external device. In this case, the driving evaluation support device 20 may receive point information about the own vehicle transmitted from other vehicles via vehicle-to-vehicle communication or the like via the communication module 21, and the driving evaluation support device 20 may total the points, so that the driving behavior evaluation system 1 does not include the management server 3.

Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also within the technical scope of the present disclosure.
