[Figure 2] FIG. 2 is a diagram illustrating an example of the software configuration of an information processing device 2. [Figure 3] FIG. 2 is a diagram illustrating the operation of the information processing device 2. DETAILED DESCRIPTION OF THE INVENTION

[0010] An information processing device 2 according to an embodiment of the present invention will be described below. FIG. 1 is a diagram illustrating an example of the hardware configuration of the information processing device 2. Note that the illustrated configuration is merely an example, and other configurations may also be used. The information processing device 2 includes a CPU 201, a memory 202, a storage device 203, a communication interface 204, an input device 205, an output device 206, and a position detector 207. The storage device 203 stores various data and programs, and is, for example, a hard disk drive, a solid-state drive, or a flash memory. The communication interface 204 is an interface for connecting to a communication network, and is, for example, an adapter for connecting to Ethernet (registered trademark), a modem for connecting to a public telephone network, a wireless communication device for wireless communication, a USB (Universal Serial Bus) connector or an RS232C connector for serial communication, etc. The input device 205 is, for example, a keyboard, a mouse, a touch panel, buttons, a microphone, etc. for inputting data. The output device 206 is, for example, a display, a printer, a speaker, etc. for outputting data. The input device 205 may be implemented as a touch panel display. The position detector 207 may be configured with, for example, a geomagnetic sensor, a gyroscope, a distance sensor, a GPS receiver, etc. Each functional unit of the information processing device 2, which will be described later, is realized by the CPU 201 reading a program stored in the storage device 203 into the memory 202 and executing the program, and each storage unit of the information processing device 2 is realized as part of the storage area provided by the memory 202 and the storage device 203.

[0011] 2 is a diagram showing an example of the software configuration of the information processing device 2. The information processing device 2 includes an emission coefficient storage unit 231, a map data storage unit 232, a road condition acquisition unit 211, an activity amount acquisition unit 212, an emission amount calculation unit 213, a route search unit 214, a current position acquisition unit 215, and a route presentation unit 216.

[0012] <Storage section> The emission coefficient storage unit 231 stores emission coefficients for calculating greenhouse gas emissions for each road condition. Road conditions can include the type of road, such as expressway or general road, weather information such as whether there is rain or snow, the slope of the road, the degree of congestion, etc. In this embodiment, it is assumed that the type of vehicle to be calculated is known, and that an emission coefficient corresponding to that type of vehicle is stored.

[0013] The map data storage unit 232 stores map data, which may include various types of data such as road data for route searches and map matching data for improving position accuracy.

[0014] <Functional section> The road condition acquisition unit 211 acquires road conditions related to roads that may be included in the route from the departure point to the destination. The type of road, such as an expressway or an ordinary road, and the degree of inclination of the road can be stored in advance for each road. The road condition acquisition unit 211 can acquire weather data provided by, for example, the Japan Meteorological Agency or a weather company. The road condition acquisition unit 211 can acquire the degree of congestion from, for example, the Road Traffic Information and Communication System Center (VICS (registered trademark)). The road condition acquisition unit 211 can also acquire the degree of congestion of a road from a server that provides map data.

[0015] The activity amount acquisition unit 212 acquires an activity amount related to traveling on roads that constitute the route. The activity amount acquisition unit 212 can acquire, for example, a distance related to road data as the activity amount. The activity amount acquisition unit 212 can calculate the activity amount by, for example, dividing the distance related to the road data by the fuel efficiency for each preset road condition. Note that if an emission coefficient for each road condition that takes fuel efficiency into consideration is registered in the emission coefficient storage unit 231, the distance related to the road data can be acquired as the activity amount. For example, the activity amount acquisition unit 212 can accept input of the vehicle's load capacity (tons) and multiply the input load capacity by the distance (km) related to the road data to calculate the transportation volume (ton-kilometers) as the activity amount.

[0016] The emission calculation unit 213 calculates the greenhouse gas emission amount. The emission calculation unit 213 reads out an emission coefficient according to the road conditions acquired by the road condition acquisition unit 211 from the emission coefficient storage unit 231, and can calculate the emission amount by multiplying the activity amount acquired by the activity amount acquisition unit 212 by the read emission coefficient.

[0017] The route search unit 214 searches for a route from the departure point to the destination. The route search unit 214 can search for a guide route from the departure point to the destination using, for example, the Dijkstra algorithm, with reference to the map data storage unit 232. The departure point may be specified by the user or may be the current location of the vehicle. The destination may be specified by the user. A location acquisition unit may be provided that acquires location information (latitude, longitude, etc.) of the departure point and destination specified by the user. In this embodiment, the route search unit 214 further searches for a route such that the total value of emissions calculated based on the emission coefficient corresponding to the road conditions and the activity amount related to the route is optimized. The total value of emissions being optimized can be, for example, the minimum total value of emissions. The total value of emissions being optimal can be, for example, the minimum total value in a local search for the route. The total value of emissions being optimal can be, for example, the total value of emissions being smaller than a standard value of emissions calculated by multiplying the standard value of the emission coefficient by the activity amount (e.g., the total distance traveled for the route).

[0018] The current position acquisition unit 215 acquires the current position of the vehicle. The current position acquisition unit 215 can calculate the current position based on information output from the position detector 207, for example.

[0019] The route presentation unit 216 presents the route searched by the route search unit 214. The route presentation unit 216 can display the route on a map, for example. For example, if there are multiple routes whose total emission amount is less than the standard emission amount described above, the route presentation unit 216 can present multiple routes, and in this case, can present a predetermined number of routes in order of the least total emission amount.

[0020] <Operation> FIG. 3 is a diagram illustrating the operation of the information processing device 2.

[0021] The information processing device 2 accepts the specification of a departure point and a destination point (S301). The information processing device 2 may accept only the destination point and use the current location as the departure point. The information processing device 2 performs a route search by optimizing the emission amount from the departure point to the destination (S302). The information processing device 2 presents the searched route (S303).

[0022] As described above, the information processing device of this embodiment can search for a driving route that reduces greenhouse gas emissions and provide support for suppressing greenhouse gas emissions.

[0023] Although the present embodiment has been described above, the above embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and equivalents thereof are also included in the present invention.

[0024] In this embodiment, the type of vehicle to be calculated is assumed to be known, but the emission coefficient storage unit 231 can store emission coefficients in association with the vehicle type and road conditions. For example, when transportation is carried out using multiple vehicles in logistics, the vehicle type for each transportation section can be input, and greenhouse gas emissions can be calculated using the emission coefficient corresponding to the vehicle type and road conditions.

[0025] In addition, in this embodiment, the optimal route is searched for using an emission coefficient for calculating greenhouse gas emissions for each road condition, but instead of or in addition to this, an emission coefficient for each operator may be used. For example, if different operators operate the route from the departure point to the destination, the emission unit value that serves as primary data may differ depending on the operator, so it is possible to calculate an optimal route based on more accurate emissions.

[0026] In addition, although the present embodiment is based on the assumption that the information processing device 2 operates independently, it is also possible to adopt a so-called server-client configuration, in which the information processing device 2 operates as a server, and the user can access the server by operating a user terminal.
