<System configuration>
[overall structure]
FIG. 1 is a diagram illustrating a configuration example of a system according to an embodiment. A system 1 according to this embodiment includes an in-vehicle device 100 and a server device 200 . The in-vehicle device 100 is mounted on the vehicle Ve. The server device 200 communicates with a plurality of in-vehicle devices 100 mounted on a plurality of vehicles Ve.

The in-vehicle device 100 basically performs route guidance processing, information provision processing, and the like for the user who is a passenger of the vehicle Ve. For example, when a destination or the like is input by the user, the in-vehicle device 100 transmits to the server device 200 an upload signal S1 including position information of the vehicle Ve and information on the designated destination. The server device 200 calculates a route to the destination by referring to the map data, and transmits a control signal S2 indicating the route to the destination to the in-vehicle device 100 . The in-vehicle device 100 provides route guidance to the user by audio output or image display based on the received control signal S2.

In addition, the in-vehicle device 100 provides various types of information to the user through interaction with the user. For example, when a user makes an information request, the in-vehicle device 100 supplies the server device 200 with an upload signal S1 including information indicating the content or type of the information request and information about the running state of the vehicle Ve. The server device 200 acquires and generates information requested by the user, and transmits it to the in-vehicle device 100 as a control signal S2.

In this embodiment, the in-vehicle device 100 outputs at least various information related to driving, such as points on the route that require guidance (also referred to as “guidance points”). Here, the guidance point corresponds to, for example, an intersection at which the vehicle Ve turns left or right, or an important passing point for the vehicle Ve to travel along the guidance route. The in-vehicle device 100 provides guidance regarding guidance points such as the distance from the vehicle Ve to the next guidance point and the traveling direction at the guidance point.

The in-vehicle device 100 is installed, for example, on the upper part of the windshield of the vehicle Ve or on the dashboard. Note that the in-vehicle device 100 may be incorporated in the vehicle Ve.

In addition, the storage unit 112 stores the map DB4. Various data required for route guidance are recorded in the map DB 4 . The map DB 4 stores, for example, road data representing a road network by a combination of nodes and links, feature information indicating features that are candidates for destinations, stop-off points, or landmarks. The map DB 4 may be updated based on the map information received by the communication section 111 from the map management server under the control of the control section 114 .

The input unit 113 is a button, touch panel, remote controller, etc. for user operation. The display unit 116 is a display or the like that displays based on the control of the control unit 114 . The microphone 117 collects sounds inside the vehicle Ve, particularly the driver's utterances. A speaker 118 outputs audio for route guidance and information provision to the driver or the like.

The sensor group 115 includes an external sensor 121 and an internal sensor 122 . The external sensor 121 is, for example, one or more sensors for recognizing the surrounding environment of the vehicle Ve, such as a lidar, radar, ultrasonic sensor, infrared sensor, and sonar. The internal sensor 122 is a sensor that performs positioning of the vehicle Ve, and is, for example, a GNSS (Global Navigation Satellite System) receiver, a gyro sensor, an IMU (Inertial Measurement Unit), a vehicle speed sensor, or a combination thereof. It should be noted that the sensor group 115 may have a sensor that allows the control unit 114 to directly or indirectly derive the position of the vehicle Ve from the output of the sensor group 115 (that is, by performing estimation processing).

The vehicle exterior camera 119 is a camera that captures the exterior of the vehicle Ve. The exterior camera 119 may be a front camera that captures the front of the vehicle, or may include a rear camera that captures the rear of the vehicle in addition to the front camera. good too. On the other hand, the in-vehicle camera 120 is a camera for photographing the interior of the vehicle Ve, and is provided at a position capable of photographing at least the vicinity of the driver's seat.

The control unit 114 includes a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), etc., and controls the in-vehicle device 100 as a whole. For example, the control unit 114 estimates the position (including the traveling direction) of the vehicle Ve based on the outputs of one or more sensors in the sensor group 115 . Further, when a destination is specified by the input unit 113 or the microphone 117, the control unit 114 generates route information indicating a guidance route to the destination, Based on the positional information and the map DB 4, route guidance is provided. In this case, the control unit 114 causes the display unit 116 to display the guidance route and the speaker 118 to output the guidance voice. Further, the control unit 114 controls the display unit 116 to display information about the music being played, video content, a map of the vicinity of the current position, or the like. Further, although the details will be described later, the control unit 114 displays the carbon offset plan proposed by the server device 200 on the display unit 116 .

It should be noted that the processing executed by the control unit 114 is not limited to being implemented by program-based software, and may be implemented by any combination of hardware, firmware, and software. Also, the processing executed by the control unit 114 may be implemented using a user-programmable integrated circuit such as an FPGA (field-programmable gate array) or a microcomputer. In this case, this integrated circuit may be used to implement the program executed by the control unit 114 in this embodiment. Thus, the control unit 114 may be realized by hardware other than the processor.

The configuration of the in-vehicle device 100 shown in FIG. 2 is an example, and various modifications may be made to the configuration shown in FIG. For example, instead of storing the map DB 4 in the storage unit 112 , the control unit 114 may receive information necessary for route guidance from the server device 200 via the communication unit 111 . In another example, instead of including the speaker 118, the in-vehicle device 100 is electrically connected to an audio output unit configured separately from the in-vehicle device 100, or by a known communication means. Audio may be output from the In this case, the audio output unit may be a speaker provided in the vehicle Ve. In still another example, the in-vehicle device 100 does not have to include the display unit 116 . In this case, the in-vehicle device 100 may perform a predetermined display by electrically connecting to a display unit provided in the vehicle Ve or the like or a user's smart phone or the like by wire or wirelessly. Similarly, instead of having the sensor group 115, the in-vehicle device 100 may acquire information output by sensors installed in the vehicle Ve from the vehicle Ve based on a communication protocol such as CAN (Controller Area Network).

[Server device]
The server device 200 generates route information indicating a guide route that the vehicle Ve should travel based on the upload signal S1 including the destination and the like received from the in-vehicle device 100 . Then, the server device 200 generates a control signal S2 related to information output in response to the user's information request based on the user's information request indicated by the upload signal S1 transmitted by the in-vehicle device 100 and the running state of the vehicle Ve. The server device 200 then transmits the generated control signal S2 to the in-vehicle device 100 .

In addition, the server device 200 generates content for providing information to the user of the vehicle Ve and interacting with the user, and transmits the content to the in-vehicle device 100 .

Also, the dialog with the user is basically a pull-type dialog that starts with a question or inquiry from the user. However, the interaction with the user may start from push-type information provision.

Furthermore, the server device 200 proposes a carbon offset for greenhouse gases emitted by the user's vehicle Ve. Specifically, the server device 200 estimates the amount of greenhouse gas emissions of the user's vehicle Ve, and proposes a plurality of carbon offset plans (hereinafter also simply referred to as "offset plans" or "plans") to the user. do.

The server device 200 mainly has a communication section 211 , a storage section 212 and a control section 214 . Each element in the server device 200 is interconnected via a bus line 210 .

The communication unit 211 performs data communication with an external device such as the in-vehicle device 100 under the control of the control unit 214 . The storage unit 212 is composed of various types of memory such as RAM, ROM, nonvolatile memory (including hard disk drive, flash memory, etc.). Storage unit 212 stores a program for server device 200 to execute a predetermined process.

The storage unit 212 includes a map DB 4 and a user registration DB 5. Various data required for route guidance are recorded in the map DB 4 . The user registration DB 5 stores information on registered users of the carbon offset service, which will be described later. Specifically, the user registration DB 5 stores information such as the name and gender of each user, as well as vehicle model data of the vehicle used by the user.

The control unit 214 includes a CPU, GPU, etc., and controls the server device 200 as a whole. Further, the control unit 214 operates together with the in-vehicle device 100 by executing a program stored in the storage unit 212, and executes route guidance processing, information provision processing, and the like for the user. For example, based on the upload signal S1 received from the in-vehicle device 100 via the communication unit 211, the control unit 214 generates route information indicating a guidance route or a control signal S2 regarding information output in response to a user's information request. Then, the control unit 214 transmits the generated control signal S2 to the in-vehicle device 100 through the communication unit 211 .

<Carbon offset>
(overview)
Next, the carbon offset according to this embodiment will be described. In this embodiment, the server device 200 proposes an offset plan for offsetting the emission of greenhouse gases such as CO ₂ caused by the user driving the vehicle Ve. In this embodiment, "carbon offset" refers to a method of compensating for greenhouse gases emitted by driving a vehicle by investing in greenhouse gas reduction activities corresponding to the amount of emissions. In the following description, CO ₂ is used as a representative greenhouse gas, but the present invention is also applicable to greenhouse gases other than CO ₂ .

FIG. 4 is a diagram illustrating an outline of carbon offset according to an embodiment. Note that the target user is assumed to be "user A". The in-vehicle device 100 mounted on the vehicle Ve of the user A transmits the driving data D1 regarding the driving of the user A to the server device 200 by the upload signal S1. The server device 200 estimates the CO ₂ emissions from the user's vehicle Ve based on the vehicle model data of the user A stored in the user registration DB 5 and the driving data D1 received from the in-vehicle device 100 . For example, the server device 200 acquires the driving behavior such as the degree of opening of the accelerator from the driving data D1, and multiplies it by a coefficient set for each vehicle type data to estimate the _CO2 emissions. Then, the server device 200 creates an offset plan according to the estimated emission amount, and transmits it to the terminal device 150 of the user as plan data D2. This makes it possible to propose an appropriate offset plan according to the actual CO ₂ emissions of individual users. Note that the server device 200 may transmit the plan data D2 to the in-vehicle device 100 instead of the terminal device 150 of the user.

User A's terminal device 150 displays a plurality of offset plans based on the received plan data D2. FIG. 5 shows a display example of the offset plan. The offset plan includes "plan name", "offset amount", and "annual membership fee". "Plan name" indicates the name of each offset plan. The user will select a preferred plan from a plurality of offset plans. In addition, the offset plan is set so that the grade increases in the order of "Bronze", "Silver", "Gold", and "Platinum", and the higher the grade, the greater the amount of greenhouse gas offset.

"Amount of offset" indicates the amount of _CO2 offset in each offset plan. For example, the "Bronze" plan is a plan in which the user's investment offsets 50% of the estimated amount of CO ₂ emitted by the user from driving the vehicle Ve. The “Silver” plan is a plan in which 100% of the amount of CO ₂ estimated to be emitted by the user from driving the vehicle Ve is offset by the user's investment. In other words, the "Silver" plan is a plan in which the _CO2 emitted by the individual is offset by itself. The “Gold” plan and the “Platinum” plan are plans in which a user's investment offsets a larger amount of CO ₂ than the amount emitted by the user.

The “offset cost (annual membership fee)” is the cost for each offset plan, and indicates the amount that the user pays to offset the emitted CO ₂ . In the example of FIG. 5, each offset plan has a contract period of one year, but the contract period is not limited to this. Moreover, the server device 200 may create an offset plan based on the user's wishes regarding the contract period.

User A selects one plan from the displayed multiple offset plans. User A's terminal device 150 transmits plan selection D3 indicating the plan selected by user A to server device 200 . User A pays the fee corresponding to the selected plan.

The server device 200 requests the business operator to perform carbon offset according to the offset plan selected by the user A. In this example, it is assumed that the operator is a plantation operator and performs carbon offset by planting trees. Assuming that user A selects the “Bronze” plan, server device 200 pays the afforestation operator the offset fee paid by user A, and performs afforestation work with 50% of the amount of CO ₂ emitted by user A as the offset amount. ask for Afforestation operators plant trees in an area equivalent to the specified amount of offset. Thus, user A's carbon offset is realized. The company that operates the server device 200 may calculate the cost of each offset plan by adding the commission of the company to the actual cost to be paid to the planter.

(offset proposal processing)
FIG. 6 is a flowchart of offset proposal processing according to the embodiment. This processing is realized by executing a program prepared in advance by the server device 200 shown in FIG. 3 and communicating with the user's in-vehicle device 100 .

First, the server device 200 acquires vehicle type data from the user registration DB 5, and acquires driving data of the user's vehicle Ve from the in-vehicle device 100 (step S11). The driving data includes, for example, at least part of the travel distance of the vehicle Ve, driving behavior (accelerator work), fuel consumption, gas station visit history (refueling amount), fuel consumption, and the like. Note that the server device 200 may acquire vehicle type data from the user's vehicle Ve.

Next, the server device 200 estimates the amount of _CO2 emissions from the user's vehicle Ve based on the acquired vehicle type data and driving data (step S12). For example, the server device 200 can estimate the CO ₂ emissions from the fuel consumption and fuel efficiency of the vehicle Ve. In addition, the server device 200 may determine an emission factor for each user based on the fuel consumption, the user's driving tendency, etc., and estimate the CO ₂ emissions by multiplying the traveling distance of the vehicle Ve by the emission factor. good. Note that the method of calculating the CO ₂ emissions is not limited to a specific method, and any known method may be used.

Next, the server device 200 creates a plurality of offset plans based on the estimated CO ₂ emissions, and transmits them to the user's terminal device 150 or the in-vehicle device 100 (step S13). Specifically, the server device 200 creates a plurality of offset plans as illustrated in FIG. 5 and presents them to the user. Since the amount of CO ₂ emissions changes according to the travel distance and fuel efficiency of the user's vehicle Ve, the offset plan created by the server device 200 differs for each user. Specifically, in each offset plan, the offset cost is calculated based on the _CO2 emissions of the user's vehicle Ve. Therefore, even for the same plan, the annual membership fee for a user of a vehicle with high _CO2 emissions is higher than that for a user of a vehicle with low _CO2 emissions.

The user compares the offset plans presented by the server device 200, selects the desired plan, and transmits it to the server device 200. When the server device 200 receives the plan selection from the user's terminal device 150 or the in-vehicle device 100 (step S14), the server device 200 requests the business operator to perform carbon offset work based on the selected offset plan (step S15).

Specifically, the server device 200 designates the CO ₂ offset amount corresponding to the offset plan selected by the user and requests the business operator to perform the work. For example, if the user's annual CO ₂ emissions estimated in step S12 is 1000 kg and the user selects the "Bronze" plan, the server device 200 designates the CO ₂ offset amount as "500 kg" and to work on. Alternatively, the server device 200 may calculate a tree planting area corresponding to the CO ₂ offset amount of "500 kg", specify the tree planting area, and request the operator to perform the work. For example, if the CO ₂ emissions of "500 kg" can be offset by planting trees in an area of 700 m ² , the server device 200 may request the operator to carry out the work of "planting trees of 700 m ² ". By planting trees in response to a request from the server device 200, the CO ₂ emitted by the user is offset.

It should be noted that, when the user selects an offset plan, the server device 200 also performs settlement processing for offset costs according to the plan. Any known method can be used to settle the offset fee. Thus, the offset proposal processing ends.
