Description

Technical Field

[0001] The present invention relates to a technology for providing information that encourages a driver of a vehicle to perform actions that contribute to safe driving.

Background Art

[0002] While traveling by automobile is fast and convenient, the number of victims of traffic accidents is still large, and safety measures in automobile driving are still one of the important social issues at present. For example, Patent Document 1 discloses a technology for providing information on the driving state of other vehicles in a manner of comparing it with information on the driving state of the host vehicle when the host vehicle enters a preset attention-arousing area. The surrounding arousal area refers to an area where traffic accidents are likely to occur, such as an intersection or a pedestrian crossing. In order to avoid traffic accidents in such an area, for example, it has a function of providing information on the driving speed of other vehicles in the area in a manner of comparing it with the driving speed of the host vehicle. When the driving speeds of the host vehicle and other vehicles are significantly different in an area where the potential risk of traffic accidents is high, the probability of traffic accidents increases. Therefore, when the driver of the host vehicle obtains information that the driving speed is different from that of other vehicles, the driver intends to adjust the driving speed of the host vehicle to be the same as that of other vehicles, thereby realizing safe driving.

[0003] Also, for example, Patent Document 2 discloses a technology for providing rest information to encourage a driver to take a rest based on the position and driving time of a vehicle in motion. Specifically, the technology disclosed in Patent Document 2 has a configuration in which, after comparing and considering the distance to a rest facility close to the current location of the vehicle and the current driving time of the driver, it encourages the driver to take a rest at an appropriate timing such that the fatigue level does not reach a dangerous level until reaching the rest facility, and intends to realize safe driving with such a configuration.

Patent Documents

[0004]

Patent Document 1

[0005] However, the technologies disclosed in Patent Documents 1 and 2 only provide drivers with information to promote safe driving, and merely providing information is not necessarily sufficient as a technology to promote safe driving. Drivers often do not take any action even when provided with information that would contribute to safe driving, except in extreme cases where the occurrence of a traffic accident is almost certain. For example, even if a driver is encouraged to take a break based on the technology in Patent Document 2, most drivers will not follow the instructions if they are not aware of their fatigue. Furthermore, even if they feel somewhat tired, it is not uncommon for them to continue driving without following the instructions if they are in a hurry to reach their destination or have already traveled close to their destination. The same applies to other information provided regarding safe driving. For example, even if a driver is informed that they should replace worn-out tires, they often do not feel the need to do so and tend to put it off. Similarly, even if a driver is informed that they should slow down because they are in a dangerous area, they often overestimate their own driving skills and think "I'll be fine," and take no action.

[0006] The present invention has been made in view of the above-mentioned problems, and aims to provide a technology that promotes safe driving behaviors among drivers, rather than merely providing information on safe driving of vehicles. [Means for solving the problem]

It is characterized by the following.

[0012] Furthermore, in order to achieve the above objective, 5The information provision program in the above invention is characterized by executing a transaction generation function that generates a person transaction, which is information including driving information of the target vehicle when a person corresponding to the person token is in a riding position, and is recorded in a distributed ledger on a distributed network corresponding to a person token, which is a non-fungible token that corresponds to the driver and / or the passenger; an output function that outputs the person transaction generated by the transaction generation function to a distributed ledger on a distributed network corresponding to the person token; and an information acquisition function that acquires the driving information included in the person transaction relating to the person token from the distributed ledger corresponding to a specific person token. [Effects of the Invention]

[0013] According to the present invention, the effect is to promote safe driving behaviors among drivers, rather than simply providing information related to safe driving of vehicles. [Brief explanation of the drawing]

[0014] [Figure 1] This is a schematic diagram showing the configuration of the information provision system according to Embodiment 1. [Figure 2] This is a schematic diagram showing the configuration of the information provision system according to Embodiment 2. [Modes for carrying out the invention]

[0015] The embodiments of the present invention will be described in detail below with reference to the drawings. The following embodiments describe the most appropriate examples of the present invention, and naturally, the content of the present invention should not be limited to the specific examples shown in these embodiments. It goes without saying that any configuration other than the specific configurations shown in the embodiments that produces similar functions and effects is also included in the technical scope of the present invention.

[0016] (Embodiment 1) First, the information provision system according to Embodiment 1 will be described. As shown in Figure 1, the information provision system according to Embodiment 1 comprises: an in-vehicle content generation unit 1 that generates in-vehicle content used by the driver and passengers in the target vehicle; a driving information generation unit 2 that generates driving information, which is information regarding the driving status of the target vehicle; a warning information provision unit 3 that provides the driver with warning information including the detected driving information; an in-vehicle content adjustment unit 4 that adjusts the content of the in-vehicle content based on the detected driving information; an in-vehicle content provision unit 5 that provides the in-vehicle content after content adjustment by the in-vehicle content adjustment unit 4; a token generation unit 6 that generates person tokens, which are non-fungible tokens corresponding to the driver and passengers, respectively; a transaction generation unit 7 that generates transactions to be stored in blocks in a distributed ledger corresponding to the person tokens; an electronic signature generation unit 8 that generates an electronic signature, which is data that proves that the generation and output of the person transaction is in accordance with the intentions of the person token holder; an output unit 9 that outputs the person transaction and the electronic signature; and an information acquisition unit 10 that accesses blocks in a distributed ledger and acquires information contained in the person transaction stored in the ledger.

[0017] The in-vehicle content generation unit 1 is for generating in-vehicle content that is used by the driver and passengers of the target vehicle when the vehicle is in use. The in-vehicle content may be one-way content such as video viewing or music listening, but in this embodiment 1, it is interactive content that assumes participation from the driver and passengers. Furthermore, the in-vehicle content may include both visual (video, text, etc.) and auditory (audio data, etc.) elements, or it may include only one of them. In this embodiment 1, the content of the in-vehicle content is the same for both the driver and passengers, consisting of both visual and auditory elements, but for example, from the perspective of preventing distracted driving, the content may be auditory only for the driver.

[0018] The in-vehicle content used in Embodiment 1 includes content in which a character corresponding to the driver and / or passengers of the target vehicle moves along a route (route) set based on the driving route of the target vehicle, and a predetermined point is given to the driver and / or the passengers associated with the character in an event that occurs in a predetermined area (access point) set on the route. To generate such in-vehicle content, the in-vehicle content generation unit 1 includes a story setting unit 11 that sets a story based on the driving route, a character setting unit 12 that sets a character to be assigned to each of the driver and passengers, an access point setting unit 13 that sets an access point where an event occurs based on the driving route, an event setting unit 14 that sets an event that occurs at the access point, and a point setting unit 15 that sets the content and criteria of the points to be given to the driver and passengers according to the result of the event or the like.

[0019] The story setting unit 11 is for setting the story of the entire content. Specifically, the story setting unit 11 has a function of setting a story based on the departure place, destination of the target vehicle, and route information assumed to pass between them. As a specific aspect of story setting, it may be possible to specifically generate a story from scratch every time the target vehicle is used, or to select one from a plurality of pre-prepared stories and adjust the story according to the specific content of the departure place, destination, and the route between them. In Embodiment 1, a story is set in which various adventures are carried out while moving along the route and the goal set at the destination is aimed at, but of course, other stories may be set.

[0020] The character setting unit 12 is for assigning characters appearing in the story set by the story setting unit 11 to the driver and passengers. For example, when the story is an adventure, after setting characters such as a brave warrior, a fighter, and a wizard, etc., for the driver and passengers, according to the roles in the vehicle (the driver drives, the passenger in the passenger seat is a navigator showing the route, etc.), or according to the attributes of the driver and passengers (gender, age, work experience, educational background, etc.), it has the function of assigning characters.

[0021] The access point setting unit 13 is for setting an access point which is a place where an event occurs during the movement of the target vehicle to the destination. The setting mode of the access point may be arbitrary, but preferably, the access point is set in a form associated with a building or the like existing on the actual movement route of the target vehicle. For example, an access point having a function as a rest area is set corresponding to a public bath or the like existing on the actual movement route, or an access point having a function as a weapons and armor sales store is set corresponding to a store of the manufacturing company or the sales / lease company of the target vehicle or a gas station. In addition, the access point set by the access point setting unit 13 may be set in association with not only real buildings but also a certain area (the whole of a specific village, etc.).

[0022] The event setting unit 14 is for setting events to occur at access points set by the access point setting unit 13. Specifically, it is desirable for the event setting unit 14 to set the event content according to the nature of the access point. For example, an event may occur where a weapons merchant appears and provides weapons and armor useful for adventures at an access point that functions as a weapons and armor shop, or a battle event with monsters may occur at an access point that is set as a dangerous area. The event setting unit 14 may set events that are designed to be enjoyable for the driver and passengers (for example, a quiz related to the access point), or it may set events that include awareness campaigns for safe driving.

[0023] The point setting unit 15 is for setting the points to be awarded to the driver and passengers according to how the in-vehicle content is used in the target vehicle. Specifically, the point setting unit 15 has the function of determining the opportunities and amounts of points to be issued, such as issuing 1 point when the usage time of the in-vehicle content (= driving time of the target vehicle) reaches a certain period of time, issuing 3 points when staying at an access point set up in a rest area, and issuing 5 points when defeating a monster in a battle event. The point setting unit 15 also has the function of setting the type of points, and it may be set to set a single type of point, or to set multiple types of points depending on the type of event. Furthermore, the point setting unit 15 can also set the function of the points, and the function of the points may be that they can be used only within the in-vehicle content, or they may be set to be able to enjoy real-life benefits such as being able to receive a certain service at a discounted price.

[0024] The driving information generation unit 2 is for generating driving information, which is information relating to the driving status of the target vehicle. The driving information generation unit 2 generates driving information that includes at least one of the following: information relating to the maintenance status of the target vehicle, information relating to the driver's driving style, or information relating to the driver's fatigue level. Specifically, the driving information generation unit 2 comprises a maintenance status detection unit 16 that detects vehicle maintenance information, which is information relating to the maintenance status of the target vehicle; a driving style detection unit 17 that detects driving style information, which is information relating to the driver's driving style in the target vehicle; a driver fatigue detection unit 18 that detects driver fatigue information, which is information relating to the driver's fatigue level associated with driving the target vehicle; and an information generation unit 19 that generates driving information based on the information detected by each detection unit.

[0025] The maintenance status detection unit 16 is for detecting vehicle maintenance information, which is information relating to the maintenance status of the target vehicle. Specifically, the maintenance status detection unit 16 has the function of detecting information relating to the maintenance status of the target vehicle, such as tire pressure, presence and degree of tire surface wear, presence and degree of engine oil deterioration, presence and degree of brake performance deterioration, presence and degree of engine performance deterioration, etc. The specific detection method by the maintenance status detection unit 16 may be to grasp the deterioration status of the parts from information about the structure and components of the target vehicle in advance and the most recent maintenance time and maintenance content for each part, or it may be based on the behavior of the target vehicle (estimating the tire surface wear status from the braking frequency, estimating the presence or absence of engine performance deterioration from the acceleration status, etc.), or the target components may be equipped with sensor equipment that can directly detect the deterioration status.

[0026] The driving style detection unit 17 is for detecting driving style information, which is information about the driver's driving style in the target vehicle. Specifically, the driving style detection unit 17 has the function of detecting information about the driver's driving style in the target vehicle, such as the timing, frequency, and intensity of braking while driving, the presence and degree of instability in steering operation, the presence and degree of instability in driving speed, and the length of driving distance. A specific detection method by the driving style detection unit 17 is, for example, to calculate an ideal driving style based on the route information while driving, then to detect the driver's actual driving style based on the operation status of the brake pedal, accelerator pedal, steering wheel, etc. in the target vehicle, and to detect information about the presence and degree of differences from the ideal driving style.

[0027] The driver fatigue detection unit 18 is for detecting driver fatigue information, which is information regarding the degree of fatigue of the driver while driving the target vehicle. Specifically, the driver fatigue detection unit 18 has the function of detecting the driver's fatigue level at a given time based on biometric information such as the driver's body temperature, heart rate, blood pressure, and respiratory status, as well as the number of blinks, pupil size, head tilt, and the presence and degree of hand tremors. Specific detection methods by the driver fatigue detection unit 18 include, for example, having the driver wear a biosensor and detecting information using the sensor, or installing a camera inside the target vehicle to film the driver and detecting information by analyzing the acquired video. Furthermore, the driver fatigue detection unit 18 may also have a configuration to detect specific actions of the driver, such as driver changes or taking breaks, and detect the driver's fatigue level based on these specific actions.

[0028] The information generation unit 19 generates driving information, which is information relating to the driving status of the target vehicle, based on at least one (preferably all) of the vehicle maintenance information, driving pattern information, and driver fatigue information detected by the maintenance status detection unit 16, the driving pattern detection unit 17, and the driver fatigue detection unit 18. Specifically, the information generation unit 19 generates information that includes vehicle maintenance information, driving pattern information, and driver fatigue information as driving information, and also has the function of generating evaluation value information, which is a value that evaluates the degree to which each piece of information has an impact on the safe driving of the target vehicle. The degree to which an impact has an impact on safe driving is a concept that includes an evaluation of the severity and urgency of the impact on safe driving. For example, if the degree to which an impact has an impact on safe driving is defined as the degree to which an accident occurs or a malfunction occurs that impedes vehicle operation, the evaluation value information is generated as a value that evaluates the severity (for example, what scale of accident or malfunction will occur, etc.) and urgency (for example, how imminent is the possibility of an accident or malfunction occurring, etc.) of the accident or malfunction that occurs.

[0029] The Warning Information Provision Unit 3 generates warning information, including detected driving information, and provides this warning information to the driver. Specifically, the Warning Information Provision Unit 3 generates improvement information, which is information regarding means to improve problem information (for example, information that may hinder safe driving, specifically information indicating the possibility of traffic accidents or malfunctions that may hinder vehicle operation, etc.) contained in the driving information generated by the Driving Information Generation Unit 2, and provides the driver with warning information, which is information including driving information and improvement information. The improvement information newly generated by the Warning Information Provision Unit 3 preferably includes not only general information that contributes to improving the problem information, but also specific information such as which part of the route the vehicle is traveling on would be best suited to address the issue (for example, in the case of tire replacement, it would be helpful to guide the driver to a store that not only sells tires but also provides replacement services, etc.). Furthermore, the driving information included in the warning information may include all the driving information generated by the driving information generation unit 2, or it may include only the information in which the value of the evaluation information corresponding to the severity and urgency in relation to safe driving, such as the occurrence of a traffic accident or the occurrence of a malfunction that impedes the operation of the vehicle, exceeds a predetermined standard value (= high severity and urgency). In this embodiment 1, the warning information provision unit 3 is configured to provide warning information only to the driver, but it is not necessary to limit the configuration to this. For example, considering that it may interfere with the driver's driving, the information may not be provided to the driver, and only to the passenger sitting in the front seat, or it may be provided to all drivers and passengers.

[0030] The in-vehicle content adjustment unit 4 adjusts the content of the in-vehicle system based on evaluation value information included in the driving information generated by the driving information generation unit 3, so that the degree of adjustment corresponds to the degree of impact on the safe driving of the target vehicle. Specifically, the in-vehicle content adjustment unit 4 has a function to adjust the content of the in-vehicle system according to the degree of evaluation value information for problem information when the driving information includes problem information (for example, information that may hinder safe driving, specifically information indicating the possibility of a malfunction that could cause a traffic accident or hinder vehicle operation, etc.).

[0031] The in-vehicle content adjustment unit 4 includes a content content adjustment unit 20 for making specific content adjustments, and a problem occurrence display adjustment unit 21 for displaying that the driving information contains a certain amount of problem information, that is, that there is a problem with the driving of the target vehicle.

[0032] The content adjustment unit 20 performs adjustment processing according to the magnitude of the evaluation value information included in the driving information (a value corresponding to the severity and urgency of the problem information in relation to the occurrence of a traffic accident or a malfunction that impedes the vehicle's operation; in this embodiment 1, a larger value indicates higher severity and urgency). When the evaluation value information is large (the severity and urgency of the problem information is high), the degree of in-vehicle content adjustment is increased, and when the evaluation value information is small (the severity and urgency of the problem information is low), the degree of in-vehicle content adjustment is decreased. As for the adjustments to the in-vehicle content, for example, the points awarded by the point setting unit 15 may be made stricter (for example, changing the awarding of 1 point from the usual 1 point awarded upon completing a predetermined event to 1 point, or changing the condition from awarding points unconditionally for defeating monsters in battle events to awarding points only if they are defeated within a predetermined time), the conditions for clearing events set by the event setting unit 14 may be made stricter (for example, increasing the difficulty of quizzes given during events, increasing the combat power of monsters appearing in battle events, etc.), the characters set by the character setting unit 12 may be made worse (for example, degrading character designs, lowering character personalities and abilities, etc.), the stories set by the story setting unit 11 may be made outdated, etc., and the content may be changed in a way that generally increases the level of discomfort for users of the in-vehicle content.

[0033] Furthermore, the adjustment method of the in-vehicle content by the content adjustment unit 20 may involve classifying the evaluation value information into multiple stages and changing the degree of adjustment of the in-vehicle content according to the stage, or changing the degree of adjustment in proportion to the value of the evaluation value information. In addition, when the evaluation value information in the problem information changes while the target vehicle is in motion, it is also preferable to change the adjustment method of the in-vehicle content according to the change. That is, if the value of the evaluation value information of the problem information increases (when the severity and urgency increase), the content adjustment is made in such a way that the user's discomfort increases further, while conversely, if the value of the evaluation value information decreases (when the severity and urgency decrease), for example, when the driver takes a necessary break and the driver's fatigue is reduced, the content adjustment is made in such a way that the discomfort decreases.

[0034] The Problem Occurrence Display Adjustment Unit 21 is designed to adjust the content of the in-vehicle content so that content users, especially passengers, can recognize that the content has been adjusted due to the occurrence of problem information, either on the in-vehicle content itself or separately from the in-vehicle content. Specifically, the Problem Occurrence Display Adjustment Unit 21 may, in its simplest configuration, make significant content adjustments to the in-vehicle content itself to the extent that it can be immediately recognized that content adjustments have been made, or it may adjust the content to explain that problem information has been confirmed through on-screen displays, audio guidance, etc., or it may adjust the background image on the screen, background music in the audio, etc., to be different from the usual (e.g., the background changes to red) to make the user aware of the problem. Although the Problem Occurrence Display Adjustment Unit 21 is not an essential component, if it is provided, it has the advantage that drivers and passengers, especially passengers, who use the in-vehicle content can clearly understand that the reason for the content adjustments is that problematic information has occurred in the driving information.

[0035] The in-vehicle content provider unit 5 is for providing the driver and passengers with in-vehicle content that has been adjusted by the in-vehicle content adjustment unit 4. Specifically, if the in-vehicle content provider unit 5 does not perform content adjustments by the in-vehicle content adjustment unit 4, it provides the in-vehicle content generated by the in-vehicle content generation unit 1 as is. However, if content adjustments have been made by the in-vehicle content adjustment unit 4, it has the function of providing in-vehicle content consisting of the adjusted content. The driver and passengers view the in-vehicle content provided by the in-vehicle content provider unit 5 and react as needed (for example, controlling characters in battle events, inputting answers in quiz events, etc.).

[0036] The token generation unit 6 is for generating person tokens, which are non-fungible tokens corresponding to the driver and passenger. A "non-fungible token" refers to a so-called NFT (Non-Fungible Token), that is, a token that has the property of being infungible with other tokens by possessing unique data, and is issued based on the Ethereum® standard ERC721, for example.

[0037] The person tokens generated by the token generation unit 6 represent the corresponding person, and basically, that person holds the person token. The person transaction generated based on the person token and the information of the corresponding person is output and stored in a block that constitutes a specific distributed ledger corresponding to that person on the decentralized network forming the blockchain.

[0038] Blockchain is a technology that uses cryptographic techniques to synchronize data among multiple computers that make up a decentralized network. Specifically, each block is composed of a collection of token information, such as agreed-upon transaction records, and information to connect to other blocks (information from the previous block). A blockchain is formed by linking multiple such blocks together. Even if data is tampered with on some of the computers, the correct data is selected by majority vote among the other computers, making it extremely difficult to destroy or tamper with the data.

[0039] The correspondence between person tokens and people will be in the form of associating the identifier of the person token with the identification information of the corresponding person. Furthermore, the generation of person tokens may be performed by the token generation unit 6 itself, or it may be performed by an external system that is directly or indirectly connected to the token generation unit 6 by issuing a predetermined command to that external system. In addition, the specific format of the person token is not limited to conforming to the Ethereum® standard ERC721, but may be any format as long as it has the property of being non-fungible and the information contained in the person transaction is stored in a block that constitutes a distributed ledger corresponding to the person token on the distributed network that forms the blockchain.

[0040] The transaction generation unit 7 is for generating person transactions that are stored in blocks in the distributed ledger that correspond to person tokens (i.e., recorded in the distributed ledger). Specifically, the transaction generation unit 7 has the function of generating information that includes, as content of a person transaction, information regarding the setting and changing of the name of the person token holder, as well as information including driving information of the target vehicle if the corresponding person was the driver or passenger. The scope of the driving information may be arbitrary, but preferably it includes information that allows for the understanding of changes in driving information during travel in the same target vehicle.

[0041] The electronic signature generation unit 8 has the function of generating an electronic signature, which is data that proves that the creation and output of information included in a person transaction is in accordance with the intentions of the person token holder. Specifically, the electronic signature generation unit 8 has the function of generating a hash value for a person transaction and generating an electronic signature by encrypting the hash value with a private key held by the person token holder. The "hash value" is a fixed-length value obtained by applying a certain calculation procedure to the original data. Since this calculation procedure is irreversible, it is considered impossible to recover the original data from the hash value. The "private key" is a sequence of numbers used in the encryption process and is configured to be decryptable by a corresponding "public key". In this embodiment 1, the transaction generation unit 7 and the electronic signature generation unit 8 are configured to create each transaction and electronic signature themselves, but it is not necessary to limit them to this, and the transaction generation unit 7 and the electronic signature generation unit 8 may have the function of only instructing an external device to create the transaction and electronic signature.

[0042] The output unit 9 is for outputting the person transaction generated by the transaction generation unit 7 and the electronic signature related to the person transaction generated by the electronic signature generation unit 8 to the distributed network corresponding to the person token. In this embodiment 1, the output unit 9 is configured to directly output the person transaction and electronic signature, but it may also be configured to simply instruct other components (including those provided outside the information provision system according to embodiment 1) to output. In this embodiment 1, the output unit 9 is directly or indirectly connected to the distributed network and is configured to output predetermined data to the distributed network. The distributed network generates a hash value for each outputted transaction and compares it with the data obtained by decrypting the corresponding electronic signature with the public key (= hash value of the transaction). If the two values ​​are different, it is determined that it is not a genuine transaction and registration is rejected. If the two values ​​match, it is determined that it is a genuine transaction and the information composed of the transaction is stored in a block that constitutes the distributed ledger. Regarding the correspondence between person transactions and distributed ledgers, for example, it can be constructed by linking the identification information of the distributed ledger with the identification information of the person transaction, or more simply, the same information as the identification information of the person transaction may be used as the identification information of the distributed ledger.

[0043] The information acquisition unit 10 is for accessing blocks in the distributed ledger and acquiring driving information related to a person that is included in person transactions stored in the ledger. Specifically, the information acquisition unit 10 has the function of accessing a distributed ledger that corresponds to a person token that corresponds one-to-one with a specific person, and acquiring driving information of the target vehicle in which the specific person was involved as a driver or passenger from the information recorded in the distributed ledger. Since each distributed ledger stores person transactions generated by the transaction generation unit 7, and person transactions contain corresponding driving information, the information acquisition unit 10 can access person transactions stored in the distributed ledger that corresponds to a specific person and acquire the driving information contained in the person transactions, thereby enabling it to grasp the changes in driving information when the specific person was in the target vehicle as a driver or passenger. The information acquired by the information acquisition unit 10 can be used to determine what kind of suitability and characteristics the specific person has as a driver or passenger, and what kind of behavioral characteristics they exhibit while traveling in a vehicle. For example, providing this information to a non-life insurance company would enable the calculation of appropriate insurance premiums, and providing this information to an automobile manufacturer would allow it to be used as data for automobile development. Since this information may be sensitive personal information, the system may be configured so that it can only be provided to third parties with the consent of the specific person concerned, or the scope of information to be provided may be determined by the specific person themselves.

[0044] Next, the advantages of the information provision system according to this embodiment 1 will be explained. First, the information provision system according to this embodiment 1 employs a configuration that changes the content of in-vehicle content used by the driver and passengers in the target vehicle while it is in motion, according to evaluation value information generated according to the degree of impact on safe driving. By adopting this configuration, if the driver or the target vehicle is in a situation that impedes safe driving, the content of the in-vehicle content will change according to the degree of impact, making it possible for the driver and passengers to recognize the abnormality. Furthermore, the greater the impact, the greater the degree of adjustment of the in-vehicle content, that is, the greater the deviation from the normal state, and the stronger the driver and passengers feel discomfort and unease. In order to resolve this discomfort and unease, the driver will take action themselves, and the passengers will strongly request action from the driver, so that actions will be taken to resolve the cause of the high evaluation value information, and ultimately the problem that is impeding safe driving will be resolved.

[0045] Individual problems that could impair safe driving include, for example, the driver's continuous driving time being longer than usual, the timing of braking being slightly later than usual, and the tire changes being delayed, causing the treads to become flattened. However, it is difficult for both the driver and passengers to accurately estimate the risks caused by each individual problem, and simply being warned that "there is a safety risk" often leads to ignoring the warning, with people thinking things like, "The driver is still young, so it'll be fine," "I didn't heed the last warning, but nothing happened then," or "I'm in a hurry today, so I'll deal with it another day when I have more time." In this embodiment 1, instead of encouraging improvement by simply conveying the existence or content of the problem information as it is, the content of the in-car content used is adjusted to create a sense of unease or discomfort in the driver and passengers, thereby motivating them to improve the problem information by resolving this unease or discomfort. This has the advantage of effectively suppressing the situation in which warnings are ignored as described above. In particular, in cases like the in-car content generated in this embodiment 1, where events occur at access points and points that benefit the player are awarded depending on how the player responds to the events, both the driver and passengers are highly focused on viewing the in-car content. Therefore, the sense of unease or discomfort experienced when the content is adjusted is higher than when viewing normal content. Consequently, the driver is expected to feel a strong need to address the problem information themselves, and the passengers are expected to strongly urge the driver to resolve the problem information as soon as possible. As a result, the problem information is resolved or mitigated quickly, and the negative impact of the problem information on safe driving is reduced.

[0046] Furthermore, in this embodiment 1, person tokens corresponding to the driver and passenger are generated, and person transactions including driving information in the target vehicle in which the driver and passenger were riding are stored in a distributed ledger on a distributed network corresponding to the person token. Since the information stored in the distributed ledger on the distributed network is virtually impossible to tamper with, the reliability of the information is high, and by using such stored information, it becomes possible to objectively grasp the behavioral characteristics of the driver and passenger during vehicle travel (for example, for the driver, how they took corrective actions in response to the evaluation value information regarding problem information, for the passenger, to what extent they encouraged the driver to take corrective actions, etc.), which results in advantages such as being able to accurately grasp the personality and ability evaluation of the driver and passenger, their behavioral characteristics as consumers, and the presence and degree of risk as an insured.

[0047] (Embodiment 2) Next, the information provision system according to Embodiment 2 will be described. In Embodiment 2, components that have the same name and reference numerals as those in Embodiment 1 will perform the same functions as those in Embodiment 1 unless otherwise specified.

[0048] Figure 2 is a schematic diagram showing the configuration of the information provision system according to Embodiment 2. As shown in Figure 2, the information provision system according to Embodiment 2 newly includes an in-vehicle content input unit 22 that inputs externally generated in-vehicle content, replacing the in-vehicle content generation unit 1 of Embodiment 1. Furthermore, the in-vehicle content adjustment unit 23 is newly equipped with a content quality adjustment unit 24 that adjusts the quality of the in-vehicle content when problem information is included in the driving information, as part of the content adjustment of the in-vehicle content.

[0049] The in-vehicle content input unit 22 is for inputting externally generated in-vehicle content. Specifically, the in-vehicle content input unit 22 is for inputting externally generated content such as television broadcasts, radio broadcasts, video content, and music content as in-vehicle content. The input content may include either video or audio, or both, and may be either unidirectional or bidirectional, but in this embodiment 2, unidirectional content will be used.

[0050] The content quality adjustment unit 24 is for adjusting the quality of in-vehicle content input via the in-vehicle content input unit 22 based on problem information included in the driving information. Specifically, the content quality adjustment unit 24 adjusts the quality of the in-vehicle content, for example, the resolution of the video portion, and at least one of the hue, saturation, and illuminance of the video portion, and at least one of the sound quality and volume of the audio portion, depending on the magnitude of the evaluation value information included in the problem information (a value corresponding to the severity and urgency of the problem information in relation to the occurrence of a traffic accident or a malfunction that impedes the driving of the vehicle. In this embodiment 2, a larger value indicates higher severity and urgency).

[0051] Next, the advantages of the information provision system according to this second embodiment will be described. The information provision system according to this second embodiment employs a configuration that adjusts not only specific content such as events and point awarding conditions within the in-vehicle content, but also the resolution, hue, saturation, and brightness of the entire video, and the sound quality and volume of the entire audio. By adopting such a configuration, it is possible to create a sense of unease or discomfort in the content user without changing the basic parts of the content, such as the point awarding conditions and the difficulty level of the events. When adjusting the basic parts of the content, complex processing such as parameter adjustment may be required, but adjusting the entire video and audio as in this second embodiment has the advantage of easily creating a sense of unease or discomfort in the content user without requiring complex processing.

[0052] Although the present invention has been described above in terms of Embodiments 1 and 2, the technical scope of the present invention should not be interpreted as being limited to the specific configurations described in the embodiments. Various modifications and applications of the above embodiments are also within the technical scope of the present invention, as long as they can realize the functions of the present invention. For example, in Embodiments 1 and 2, the in-vehicle content provision unit 5 provided in-vehicle content to all drivers and passengers in the target vehicle, but it is also possible to provide it to only some people, such as only the driver or only the passengers. Furthermore, the in-vehicle content generation unit 1 and the in-vehicle content input unit 22 generated and input in-vehicle content with common content for all drivers and passengers, but it is also possible to supply different in-vehicle content to each driver and passenger. Furthermore, while Embodiments 1 and 2 only show examples of adjusting the content in a way that reduces the content and quality of in-vehicle content when the evaluation value information in the driving information becomes a poor value, content adjustment is not limited to this direction. For example, if the evaluation value information improves while the target vehicle is in motion (for example, if the driver fatigue information changes to a good level after taking a break), it is of course possible to adjust the content in a way that improves the content. Increasing the value of the evaluation value information when the impact is large is just one example, and if the value of the evaluation value information differs depending on the degree of impact, it is of course possible to set the evaluation value information in other ways.
