[0010] Hereinafter, embodiments of an information providing device, an in-vehicle device, and an information providing method disclosed in the present application will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the embodiments described below.

[0011] First, the configuration and processing of an information providing system according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram illustrating the information providing system according to an embodiment.

[0012] 1, the information providing system 1 includes an information providing device 10, a vehicle V, an in-vehicle device 20, a terminal device 30, and a terminal device 40. For example, the vehicle V is an automobile.

[0013] It is also assumed that the devices in the information providing system 1 are connected to each other via a network N (for example, the Internet).

[0014] For example, the in-vehicle device 20 is a drive recorder mounted on the vehicle V. Also, for example, the information providing device 10 is a server. Also, for example, the terminal device 30 is a personal computer. Also, for example, the terminal device 40 is a smartphone.

[0015] The in-vehicle device 20 includes a camera and an output device, such as a display device and an audio output device such as a speaker that outputs audio.

[0016] The in-vehicle device 20 and the terminal device 30 are connected to the information providing device 10 via a network N so as to be able to perform data communications therewith. For example, the network N is the Internet.

[0017] Here, the driver of the vehicle V belongs to an organization. It is assumed that a type is specified for the organization.

[0018] For example, the driver of vehicle V belongs to a corporation with a specified industry. The driver drives vehicle V as part of his / her job. The information provision system 1 evaluates the driver regarding safe driving and the like, and provides the driver with the evaluation results.

[0019] The information providing system 1 provides the evaluation result to the in-vehicle device 20, the terminal device 30, or the terminal device 40. The terminal device 30 and the terminal device 40 may be used by the driver.

[0020] The flow of processing in the information providing system 1 will be described with reference to Fig. 1. As shown in Fig. 1, first, the information providing device 10 acquires a score from the in-vehicle device 20 (step S1).

[0021] Here, for example, the score is the degree of safe driving by the driver of the vehicle V. The score may also include other factors such as the degree of fuel-saving driving.

[0022] The information providing device 10 calculates an evaluation value of the drivers in the entire organization or in the same category based on the scores (step S2).

[0023] The entire organization is all organizations that use the information provision system 1. The information provision system 1 calculates a relative evaluation value (for example, a rank and a deviation value) of the driver to be evaluated among the drivers of the entire organization.

[0024] Furthermore, the information providing system 1 calculates a relative evaluation value (for example, a rank and a deviation value) of the driver to be evaluated among drivers who belong to organizations of the same type as the organization to which the driver to be evaluated belongs.

[0025] The information providing device 10 provides the calculated evaluation value to the terminal device 40 (step S3). The information providing device 10 may provide the evaluation value by displaying it on a screen, or by text message or voice.

[0026] Furthermore, the information providing device 10 may provide the evaluation value to the in-vehicle device 20 or the terminal device 30.

[0027] The configuration of the information providing device 10 will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example of the configuration of the information providing device according to the embodiment.

[0028] As shown in FIG. 2, the information providing device 10 includes a communication unit 11, a storage unit 12, and a control unit 13.

[0029] The communication unit 11 is an interface for transmitting and receiving data to and from other devices, and is, for example, a network interface card (NIC).

[0030] The control unit 13 and memory unit 12 of the information providing device 10 are realized by a computer or various circuits having, for example, a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), flash memory, input / output ports, etc.

[0031] The information providing device 10 may also acquire programs and various information via other computers or portable recording media connected via a wired or wireless network.

[0032] The storage unit 12 stores evaluation information 121 and organization information 122 .

[0033] As shown in Fig. 3, the evaluation information 121 is information in which drivers (users) are associated with the organizations to which each driver belongs and their scores. Fig. 3 is a diagram showing an example of the evaluation information.

[0034] The user ID is an ID for identifying the driver. The organization ID is an ID for identifying the organization to which the driver belongs. The organization ID is an ID for identifying the organization.

[0035] "Dangerous behavior," "Violation of road traffic laws," "Driver inattention," "Driver characteristics," "e-learning," and "Eco-driving" are score items.

[0036] That is, there are scores corresponding to multiple items such as "risky behavior," "traffic violation," "driver carelessness," "driver characteristics," "e-learning," and "eco-driving." Here, a higher score is considered more desirable.

[0037] For example, the score "risky behavior" is a score that is deducted when dangerous behavior such as sudden starts, sudden acceleration, or sudden steering is observed.

[0038] For example, the score "traffic violation" is a score that is deducted when behavior violates traffic laws.

[0039] For example, the score "Driver Inattention" is a score that is deducted when behavior that is considered to be inattention, such as drowsy driving or distracted driving, is recognized from the image of the driver captured by the in-camera.

[0040] For example, the score "driver characteristics" is a score that is deducted when behavior that could lead to dangerous driving (frequent acceleration and deceleration, etc.) is observed.

[0041] For example, the score "e-learning" is a score that is added according to the number of times or attendance rate of a designated traffic safety course via e-learning. Also, scoring may be based on the score of a confirmation test of the e-learning.

[0042] For example, the score "eco-driving" is a score that is added when fuel efficiency (amount of fuel consumed per distance traveled) is maintained below a certain value.

[0043] In addition to the items explained so far, there may be an item such as "good driving" relating to considerate driving (for example, yielding to others, gentle braking).

[0044] For example, FIG. 3 shows that a driver with a user ID of "U001" belongs to an organization with an organization ID of "C01."

[0045] For example, Figure 3 shows that the scores for driver "U001" in "Dangerous Behavior," "Violation of Road Traffic Laws," "Driver Inattention," "Driver Characteristics," "e-learning," and "Eco-Driving" are 7, 9, 5, 7, 5, and 8, respectively.

[0046] As shown in Fig. 4, the organization information 122 is information that associates organizations with the types of each organization. Fig. 4 is a diagram showing an example of organization information.

[0047] The organization ID is an ID for identifying an organization. The type is the type of the organization. For example, the organization is a corporation. Also, for example, the type is the industry.

[0048] The organization information 122 also includes information about the settings of the in-vehicle devices for each organization. The information about the settings is expressed by whether or not the vehicle is equipped with an outer camera, an inner camera, an acceleration sensor, and the like.

[0049] For example, Fig. 4 shows that the type of organization with organization ID "C01" is "transportation industry." Fig. 4 also shows that the vehicle of organization "C01" is equipped with an outer camera, an inner camera, and an acceleration sensor.

[0050] The control unit 13 includes an acquisition unit 131, a calculation unit 132, and a provision unit 133. For example, the acquisition unit 131, the calculation unit 132, and the provision unit 133 are realized by the CPU of a computer reading and executing a program stored in a ROM.

[0051] In other words, the subject of each process performed by the acquisition unit 131, the calculation unit 132, and the provision unit 133 is the control unit 13.

[0052] The acquisition unit 131 acquires the safe driving scores of a plurality of drivers who belong to an organization.

[0053] The calculation unit 132 calculates a first evaluation value and a second evaluation value based on the score.

[0054] The first evaluation value is a relative evaluation value of the driver to be evaluated among the plurality of drivers.

[0055] For example, the calculation unit 132 calculates a first evaluation value, which is a statistical value related to the score of the driver to be evaluated among the plurality of drivers, and is a statistical value when the scores of the plurality of drivers are used as a population.

[0056] The calculation unit 132 calculates, as the second evaluation value, a ranking of the scores and a statistical value related to the variation. The statistical value is, for example, a ranking, a standard deviation, a deviation value, etc. In particular, the standard deviation and the deviation value are examples of statistical values ​​related to the variation.

[0057] The second evaluation value is a relative evaluation value among drivers who belong to organizations of the same type as the driver to be evaluated.

[0058] For example, the calculation unit 132 calculates a second evaluation value, which is a statistical value related to the score of the driver to be evaluated, when the population is the scores of drivers who belong to organizations that have the same organizational type as the driver to be evaluated.

[0059] For example, the calculation unit 132 calculates the ranking and deviation value of the score of the driver "U001" as the first evaluation value when all drivers whose scores are registered in the evaluation information 121 are used as the population.

[0060] Furthermore, for example, the calculation unit 132 calculates the ranking and standard deviation of the score of driver "U001" as the second evaluation value when the population is made up of drivers whose scores are registered in the evaluation information 121 and who belong to an organization whose type is "transportation industry."

[0061] The calculation unit 132 may calculate the first evaluation value and the second evaluation value for the score of each item, or may calculate the total score.

[0062] This allows the driver to know his or her relative evaluation not only within the organization to which he or she belongs, but also within organizations of the same type and the entire organization, thereby increasing motivation for safe driving.

[0063] Furthermore, the calculation unit 132 calculates a second evaluation value based on the type of organization to which the driver to be evaluated belongs, which is obtained by referring to the organization information 122.

[0064] By storing the type of business for each organization in this way, the information providing device 10 can easily calculate the second evaluation value.

[0065] Also, as shown in Figure 4, since each organization has different vehicle settings, the scores activated for each organization may differ.

[0066] For example, the score "Driver Inattention" is obtained based on the image captured by the in-camera. Therefore, the score "Driver Inattention" is enabled in organizations that have in-cameras and disabled in organizations that do not have in-cameras.

[0067] The acquisition unit 131 acquires scores corresponding to one or more items that are validated in the organization, among a plurality of items related to the driver's safe driving.

[0068] Then, the calculation unit 132 calculates the first evaluation value and the second evaluation value based on the total value of the acquired scores adjusted according to the items enabled in the organization.

[0069] For example, suppose there are scores for the six items shown in Figure 3, and the maximum score for each is 10.

[0070] In organization "C01," scores for six items are enabled, so the maximum total score is 60.

[0071] On the other hand, for organization "C02," the score "driver inattention" is disabled and the scores of the five items are enabled, so the maximum total score is 50.

[0072] In this case, the calculation unit 132 corrects the total score value for the drivers belonging to the organization "C02" by 60 / 50 times (1.2 times), and then calculates the first evaluation value and the second evaluation value.

[0073] By matching the maximum total score values ​​between organizations in this way, it is possible to perform evaluations that take into account differences in vehicle settings between organizations.

[0074] The providing unit 133 displays a screen showing the first evaluation value and the second evaluation value on a terminal device used by the driver to be evaluated.

[0075] This allows the driver to intuitively grasp the first evaluation value and the second evaluation value.

[0076] The terminal devices used by the driver to be evaluated include not only the terminal device 30 and the terminal device 40 but also the in-vehicle device 20.

[0077] The providing unit 133 provides the first evaluation value and the second evaluation value by displaying the evaluation result display screen 500 on the terminal device.

[0078] Furthermore, when an evaluation value is provided to the in-vehicle device 20, the in-vehicle device 20 acquires the first evaluation value and the second evaluation value, and causes an output device provided in the vehicle in which the in-vehicle device 20 is installed to output information indicating the first evaluation value and the second evaluation value. For example, the output device is a display device or an audio output device.

[0079] This allows the driver to check the evaluation value inside the vehicle and use the evaluation results in driving.

[0080] The in-vehicle device 20 may have the same functions as the information providing device 10. For example, the in-vehicle device 20 acquires scores from a plurality of in-vehicle devices through vehicle-to-vehicle communication, and calculates a first evaluation value and a second evaluation value of the driver based on the acquired scores.

[0081] 5 is a diagram showing an example of an evaluation result display screen 500. As shown in FIG. 5, an evaluation result display screen 500 displays the ID of the driver (user), the ID of the organization to which the driver belongs, and the type of organization.

[0082] Furthermore, the evaluation result display screen 500 displays the score (solid line) of each item and the overall average (dashed line) of the driver "U001" to be evaluated in a radar chart.

[0083] In addition, the area 501 displays a first evaluation value and a second evaluation value related to the total score (points) of the driver "U001."

[0084] Area 501 shows that the total score for driver "U001" is 41, with the maximum score being 60.

[0085] Area 501 also shows that the ranking and deviation value of the total value within the company (organization "C01") are "8th" and "52", respectively.

[0086] Area 501 also shows that the ranking and deviation value of the total value in the same industry (type "transportation") are "39th" and "53," respectively. The ranking and deviation value in the same industry are examples of second evaluation values.

[0087] Also, area 501 shows that the overall ranking and deviation value of the total value (all drivers in evaluation information 121) are "181st" and "56," respectively. The overall ranking and deviation value are an example of a first evaluation value.

[0088] Area 502 displays the score (points) for each item, as well as the ranking and deviation value for the company, the same industry, and the overall ranking. Area 502 also displays the number of occurrences for some items.

[0089] For example, area 502 shows that driver "U001" has a score of 7 for "Dangerous Behavior," the number of incidents is 1, and the rankings / standard deviations for his company, the same industry, and the overall company are "5th / 55," "23rd / 54," and "130th / 61," respectively.

[0090] A message according to the score is displayed in area 503. In the example of Fig. 5, a message "Make sure to stop at intersections without traffic lights..." is displayed in area 503.

[0091] Furthermore, the providing unit 133 may output a text message indicating the first evaluation value and the second evaluation value to a terminal device used by the driver to be evaluated. For example, the providing unit 133 provides the text message via email, a social networking service (SNS), or the like.

[0092] This allows the driver to accurately grasp the first evaluation value and the second evaluation value.

[0093] 6 is a flowchart showing the processing procedure of the information providing device according to the embodiment. As shown in FIG. 6, first, the information providing device 10 acquires the driver's score (step S101).

[0094] The information providing device 10 may acquire the score from the in-vehicle device 20, or may calculate the score based on information collected from the in-vehicle device 20, etc. For example, the information providing device 10 calculates the score based on behavior estimated from location information collected from the in-vehicle device 20.

[0095] Next, the information providing device 10 calculates a relative evaluation value among all drivers (step S102).

[0096] For example, the information providing device 10 calculates a relative evaluation value for a population of all drivers registered in the evaluation information 121.

[0097] Next, the information providing device 10 calculates a relative evaluation value among all drivers who belong to organizations of the same type (step S103).

[0098] For example, the information providing device 10 calculates a relative evaluation value for a population of drivers who belong to corporations in the same industry.

[0099] Then, the information providing device 10 provides the calculated evaluation value (step S104).

[0100] The information providing device 10 can provide the rating value by displaying it on a screen, sending a text message, or by voice.

[0101] For example, the information providing device 10 may notify the driver of the evaluation value periodically (for example, once a month).

[0102] So far, an embodiment has been described in which the organization is a corporation and the type is an industry. That is, the acquisition unit 131 acquires the safe driving scores of multiple drivers who belong to the corporation, which is the organization. Furthermore, the calculation unit 132 calculates, as the second evaluation value, a relative evaluation value among drivers who belong to corporations that share the same industry type as the corporation to which the driver to be evaluated belongs.

[0103] This can improve the driver's awareness of safe driving in their work.

[0104] On the other hand, the organization and type are not limited to those described in the embodiment. For example, the type may be the occupation of each driver (including whether or not they are a professional driver), the area of ​​residence, the gender, or the age. Furthermore, the organization may be the driving school attended by the driver currently undergoing driving lessons.

[0105] Further advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
