Description

[Technical field]

[0001] The present invention relates to a vehicle substitution simulation device and a vehicle substitution simulation method that acquire ride information including travel distance information and route point information of an internal combustion engine vehicle driven by a user from the transition of position information of the user's information terminal, and estimate charging information for each route point when the user switches to an electric vehicle (electric automobile) based on the ride information. [Background technology]

[0002] In recent years, various efforts have been made to achieve carbon neutrality in order to realize a sustainable society. For this reason, automobile manufacturers and others have begun selling EVs (electric vehicles) that do not emit gases such as carbon dioxide while driving, and for users, choosing an electric vehicle is becoming an issue to consider when purchasing their next vehicle. On the other hand, at present, it has been pointed out that the distance that an electric vehicle can travel on a single charge (distance per charge) is generally shorter than the distance that an internal combustion engine vehicle (e.g., a gasoline vehicle) can travel on a full tank of gasoline. It has also been pointed out that the time required to charge an electric vehicle is generally longer than the time it takes to fill up an internal combustion engine vehicle (e.g., a gasoline vehicle). For this reason, it is not easy for users to grasp, in particular, how many times and how long they will need to charge at charging facilities outside the home if they were to switch to an electric vehicle and drive in the same manner as their current internal combustion engine vehicle, and this has not yet resolved users' concerns when considering a trade-in. In this regard, Patent Document 1 discloses a technique for accurately calculating the amount of battery power consumption required for an electric vehicle to travel on a road link. Specifically, the technique discloses a technique for accurately calculating the amount of battery power consumption required for an electric vehicle to travel on a specific road section based on an estimated number of stops on the road section. Non-Patent Document 1 discloses a technology for a vulnerable person monitoring system that uses acceleration data together with location information measured by a smartphone, etc. to determine the behavior of a user of a smartphone, etc. In this technology, the user's behavior is determined to be whether they are riding in a vehicle, riding on a train, walking, etc. However, the technology described in Patent Document 1 does not allow a user to know how much battery power will be consumed by the usage of the vehicle in a day, especially if the user switches to an electric vehicle and drives in the same manner as the current internal combustion engine vehicle. Therefore, in order to know how much power the battery will consume, the user must analyze the driving manner of the current internal combustion engine vehicle and calculate the predicted power consumption, which is practically difficult for the user. For this reason, the user's anxiety when considering replacing the vehicle has not been alleviated. [Prior art documents] [Patent documents]

[0005] If a user were to switch from their current internal combustion engine vehicle to an electric vehicle (electric car) and drive in the same manner as their current internal combustion engine vehicle, it would be hoped that it would be possible to estimate charging information, including the amount of power consumed by the battery, from the user's daily vehicle usage, thereby alleviating the anxiety users have when considering a vehicle replacement.

[0006] The present invention has been made in consideration of such problems, and aims to provide a vehicle substitution simulation device and a vehicle substitution simulation method that acquire ride information including travel distance information and route information of an internal combustion engine vehicle driven by a user from the transition of position information of the user's information terminal, and estimate charging information including battery power consumption etc. based on the acquired ride information when the user switches from an internal combustion engine vehicle to an electric vehicle (electric car) and adopts a driving mode similar to that of the current internal combustion engine vehicle. In this way, the user's anxiety can be alleviated by providing objective information for the user when considering a replacement purchase. [Means for solving the problem]

[Figure 6] 5 is a flowchart showing a vehicle substitution simulation process according to the embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] A preferred embodiment of the vehicle substitution simulation device of the present invention will be described below with reference to the drawings. Fig. 1 shows a basic configuration of a vehicle substitution simulation system 100. The vehicle substitution simulation system 100 includes a vehicle substitution simulation device 1, a mobile terminal 20A, a vehicle 20, and a communication network 30.

[0021] The mobile terminal 20A is a PC, a smartphone, a tablet terminal, or the like, of a user who owns the vehicle 20. Note that application software for linking with the vehicle 20 of the user may be installed in the mobile terminal 20A. The mobile terminal 20A acquires speed information and vibration information measured by an acceleration sensor, a vibration sensor, etc. included in the mobile terminal 20A, and receives GPS satellite signals using a GPS (Global Positioning System) sensor to acquire position information (latitude and longitude) of the mobile terminal 20A and time information when the position information is measured. The mobile terminal 20A transmits the acquired speed information, vibration information, position information, time information, etc. together with identification information (terminal ID) of the mobile terminal 20A to the vehicle substitution simulation device 1. The vehicle substitution simulation device 1 stores the received position information of the mobile terminal 20A (i.e., the position information of the vehicle 20) in association with the identification information (terminal ID) of the mobile terminal 20A.

[0022] A user may instruct (input) via the mobile terminal 20A to the vehicle substitution simulation device 1 on the simulation process of switching from the vehicle 20 (internal combustion engine vehicle) owned by the user to an electric vehicle, and output information regarding the simulation results output from the vehicle substitution simulation device 1 may be displayed.

[0023] The vehicle 20 is an internal combustion engine vehicle (for example, a gasoline vehicle). For example, if the vehicle 20 is a connected car based on telematics technology, the vehicle 20 is capable of communicating with a connected system (not shown) operated by the vehicle manufacturer of the vehicle 20. Therefore, the vehicle substitution simulation device 1 may be configured to receive the position information of the vehicle 20 together with time information from the connected system (not shown) via the communication network 30, instead of the position information of the mobile terminal 20A. Hereinafter, unless otherwise specified, the vehicle 20 refers to an internal combustion engine vehicle. The outline of the system configuration in this embodiment has been described above. Next, each configuration will be described.

[0024] <Vehicle replacement simulation device 1> Fig. 2 is a block diagram showing a basic configuration of the vehicle substitution simulation device 1. As shown in Fig. 2, the vehicle substitution simulation device 1 includes a control unit 11, a storage unit 12, a communication unit 13, a display unit 14, and an input unit 15.

[0025] The control unit 11 is composed of an arithmetic processing device such as a microprocessor, and controls each unit constituting the vehicle substitution simulation device 1. The control unit 11 will be described in detail later.

[0026] The storage unit 12 is composed of a semiconductor memory or the like, and stores various programs such as control programs called firmware or operating systems, programs for acquiring position information of each mobile terminal 20A, simulation processing, output processing, etc., as well as various other information such as map information and electric vehicle performance information. 2, the storage unit 12 includes a map information storage unit 121 and an electric vehicle information storage unit 123. In the present embodiment, the map information includes charging facility information, but is not limited to this. The charging facility information may be stored in a charging facility information storage unit (not shown) or the like.

[0027] The map information storage unit 121 stores facility information including road information, facility type information indicating attributes of each facility for a plurality of facilities, and location information of the facility linked to the facility. In the present embodiment, the facility information includes charging facility information. The charging facility information includes, for example, facility type information indicating the charging facility, a charging facility identification number (charging facility identification ID) for identifying the charging facility, a charging facility name, location information of the charging facility (including road information facing the charging facility), a telephone number, an address, business hours, and power supply performance information of a charger installed in the charging facility. Here, the power supply performance information indicates, for example, a charging method (normal charging, rapid charging) and an output amount (power supply amount per hour; in the case of the CHAdeMO standard, it is approximately 20 kW to 50 kW, and there are also rapid charging of 60 kW, 90 kW, 150 kW, 250 kW, etc., unique to each manufacturer). Note that the map information storage unit 121 may include, for example, refueling facility (gas station) information in addition to the charging facility information. The refueling facility information includes, for example, facility type information indicating the refueling facility, the name of the refueling facility, and location information of the refueling facility (including information about the road facing the refueling facility).

[0028] The electric vehicle information storage unit 123 stores electric vehicle performance information for each vehicle type of electric vehicles sold by vehicle manufacturers, etc. Fig. 3 is a diagram showing an example of electric vehicle information. As shown in Fig. 3, the electric vehicle performance information includes, for each commercially available electric vehicle, model information of the electric vehicle (including the vehicle name, etc.), battery capacity (kWh), average electricity consumption (Wh / km), mileage per charge, compatible normal charging (normal charging 3 kWh or 6 kWh), and compatible quick charging (maximum compatible quick charging output; for example, maximum 50 kW, maximum 70 kW output). An electric vehicle is not capable of any normal charging or any rapid charging, and the normal charging output amount and rapid charging output amount that the model of the electric vehicle can support are determined in advance according to the model of the electric vehicle. As shown in Fig. 3, by selecting the model of the electric vehicle, the normal charging output and rapid charging output that the electric vehicle can support are determined.

[0029] The storage unit 12 has been described above, but for example, the facility information stored in the map information storage unit 121 may be configured to be stored in advance, or may be configured to be downloaded as needed from a server device (not shown) or the like connected to the communication network 30. Furthermore, this information may be appropriately corrected in response to user input or the like.

[0030] The communication unit 13 has a DSP and the like, and realizes wireless communication or wired communication between the mobile terminal 20A and other devices (for example, the above-mentioned server, etc.) via the communication network 30 in compliance with standards such as LTE (Long Term Evolution), 4G (4th Generation), and 5G (5th Generation) and Wi-Fi (registered trademark). The communication network 30 is realized by a network such as the Internet or a mobile phone network, or a network that combines these. Also, a LAN (Local Area Network) may be included as part of the network.

[0031] The display unit 14 is configured with a display device such as a liquid crystal display, an organic electroluminescence panel, etc. The display unit 14 receives an instruction from the control unit 11 and displays an image. The input unit 15 is composed of an input device (not shown) such as a physical switch called a numeric keypad or a touch panel provided over the display surface of the display unit 14.

[0032] Next, the control unit 11 will be described in detail. The control unit 11 is composed of a microprocessor having a CPU, RAM, ROM, I / O, etc. The CPU executes each program read from the ROM or storage unit 12, and during execution, reads information from the RAM, ROM, and storage unit 12, writes information to the RAM and storage unit 12, and transmits and receives signals to and from the communication unit 13. In this way, the processing in this embodiment is realized by the cooperation of the hardware and software (programs).

[0033] As shown in FIG. 2, the control unit 11 includes, as functional blocks, a position information acquisition unit 110, a ride information acquisition unit 111, an SoC calculation unit 112, and an output unit 113.

[0034] The position information acquisition unit 110 acquires movement information including a time transition of the position information from the mobile terminal 20A, which is an information terminal possessed by each user. Specifically, the position information acquisition unit 110 acquires, for example, position information (latitude and longitude) of the mobile terminal 20A, which is determined by receiving a GPS satellite signal using a GPS sensor of the mobile terminal 20A, and time information when the position information is determined, from the mobile terminal 20A. The position information acquisition unit 110 may also acquire speed information and vibration information measured by an acceleration sensor, a vibration sensor, or the like included in the mobile terminal 20A, together with the position information, from the mobile terminal 20A. The position information acquisition unit 110 stores the acquired position information, time information, speed information, vibration information, and the like of each mobile terminal 20A in the storage unit 12 by linking them to the terminal ID (for example, the telephone number of the mobile terminal 20A) of each mobile terminal 20A.

[0035] The ride information acquisition unit 111 acquires ride information including at least travel distance information and route point information of the vehicle 20 driven by the user from travel information acquired during a predetermined period (for example, one day). In the following, for example, an example will be described in which, during a "day" set as a predetermined period in the instructions for the simulation process of switching from vehicle 20 to an electric vehicle received from the user of mobile terminal 20A, the vehicle departs from home, travels to one or more facilities such as restaurants, parks, shopping malls, etc. as destinations (waypoints), and then returns home.

[0036] Specifically, for example, when the ride information acquisition unit 111 receives an instruction (input) from the user of the mobile terminal 20A for a simulation process in which the user switches from their vehicle 20 to an electric vehicle, the ride information acquisition unit 111 reads out from the storage unit 12 the position information, time information, speed information, vibration information, etc. of the mobile terminal 20A stored in the storage unit 12, the position information, time information, speed information, vibration information, etc. for "one day" that is set as a predetermined period of the instruction. The ride information acquisition unit 111 determines the state of the user (for example, "riding a vehicle", "riding a train", "walking", etc.) using the read position information, time information, etc. for the predetermined period "one day", the map information in the map information storage unit 121, and a known method such as Non-Patent Document 1. For example, when the temporal transition of the position information of the mobile terminal 20A matches the position information of the nodes on the road (e.g., intersections, bends, end points, etc. of the road) and the links which are the routes connecting each node in the map information of the map information storage unit 121, and the speed information of the mobile terminal 20A is equal to or greater than a predetermined value (e.g., 10 km / h), the ride information acquisition unit 111 determines that the user is "riding in a vehicle." Note that the ride information acquisition unit 111 may determine the first position information of the mobile terminal 20A which is determined to be "riding in a vehicle" for the first time in the day as the user's home and acquire it as the starting position information.

[0037] Furthermore, when the temporal transition of the position information of the mobile terminal 20A matches the information on a railway line (public transportation) in the map information of the map information storage unit 121, and the speed information of the mobile terminal 20A is equal to or greater than a predetermined value (e.g., 10 km per hour), the ride information acquisition unit 111 may determine that the user of the mobile terminal 20A is "on a train (travel by public transportation)". In this case, the ride information acquisition unit 111 excludes the position information of the mobile terminal 20A during the period determined to be "on a train" as travel other than that of the vehicle 20. Furthermore, when the time transition of the position information of the mobile terminal 20A matches the node on the road (e.g., intersection, bend, end point, etc. of the road) and the position information of the link which is the route connecting each node in the map information of the map information storage unit 121, but the speed calculated from the time transition of the position information of the mobile terminal 20A is, for example, 4 km per hour or less, the ride information acquisition unit 111 may determine that the user of the mobile terminal 20A is "walking". In this case, the ride information acquisition unit 111 excludes the position information of the mobile terminal 20A during the period determined to be "walking" as movement other than that of the vehicle 20. Furthermore, when the time transition of the location information of the mobile terminal 20A indicates that the mobile terminal 20A is located within a predetermined range (e.g., a radius of 500 m) for a predetermined time (e.g., 30 minutes, 1 hour, etc.) or more, if there is a facility such as a restaurant, park, or shopping mall at that location in the map information of the map information storage unit 121, the ride information acquisition unit 111 may determine that the user of the mobile terminal 20A is staying at that facility and acquire the facility as route information. Note that, when the user returns to his / her home from the facility he / she last visited, the ride information acquisition unit 111 preferably acquires the user's home as route information. Furthermore, when the user leaves his / her home and does not return to his / her home in the evening (or at night), for example, to a travel destination or a business trip destination, the ride information acquisition unit 111 may acquire the facility of the travel destination or business trip destination as route information.

[0038] The ride information acquisition unit 111 then calculates the travel distance between each of the route points included in the route point information by the vehicle 20 from the transition of the position information during the time when the user's state is only "riding the vehicle", and acquires this as travel distance information. The ride information acquisition unit 111 outputs the acquired departure position information, travel distance information, route point information, etc. to the SoC calculation unit 112.

[0039] The SoC calculation unit 112 calculates the remaining amount of power (SoC (State Of Charge)) of the electric vehicle for each stopover point as SoC information when the user switches from the vehicle 20 to an electric vehicle, based on the electric vehicle performance information and boarding information in the electric vehicle information storage unit 123. Specifically, the SoC calculation unit 112 can calculate the amount of power consumption required for the electric vehicle to travel between route points by calculating the product of two values ​​as shown in Equation 1 based on, for example, travel distance information (travel distance between route points in route point information) acquired by the ride information acquisition unit 111 and the average power consumption (Wh / km) of the electric vehicle. Note that the average power consumption is set for each type of electric vehicle as shown in Fig. 3. Amount of electricity required for travel between stops = Average electricity cost × Travel distance between stops (Formula 1) When the battery of the electric vehicle is fully charged (SoC is 100%) at the time of departing from home, the SoC calculation unit 112 calculates the SoC for each k-th route point in the route point information using Equation 2. Here, k is an integer from 1 to n, and the n-th route point indicates, for example, the home of the user who has just returned home. Also, the battery capacity is set for each type of electric vehicle as shown in FIG. 3. SoC(kth stop) = 100% -(Σ 経由地間 (Power consumption required for travel between stops) / (Battery capacity) x 100 (Formula 2)

[0040] The output unit 113 outputs to the mobile terminal 20A via the communication network 30 the SoC information for each route point calculated by the SoC calculation unit 112 when the user switches from the vehicle 20 owned by the user to an electric vehicle and adopts a driving style similar to that of the vehicle 20.

[0041] <Mobile terminal 20A> The functional blocks of the mobile terminal 20A will be described with reference to the block diagram of FIG. As shown in FIG. 4, the mobile terminal 20A includes a control unit 21, a storage unit 22, a communication unit 23, a sensor unit 24, a display unit 25, and an input unit .

[0042] The control unit 21 is configured with an arithmetic processing device such as a microprocessor, and controls each part constituting the mobile terminal 20 A. The control unit 21 will be described in detail later.

[0043] The storage unit 22 is composed of a semiconductor memory or the like, and stores various information such as a control program called firmware or an operating system, and a program that executes a function of transmitting position information, time information, and the like to the vehicle substitution simulation device 1. In the figure, position information 221, vibration information 222, and speed information 223 are illustrated as information stored in the storage unit 22. Note that the storage unit 22 may store information other than these.

[0044] The location information 221 includes location information (latitude and longitude) of the mobile terminal 20A obtained by receiving a GPS satellite signal using a GPS sensor included in the sensor unit 24 described later, and time information when the location information is measured. The vibration information 222 includes vibration information of the mobile terminal 20A measured by an acceleration sensor, a vibration sensor, or the like included in the sensor unit 24, which will be described later. The speed information 223 includes speed information on the moving speed of the mobile terminal 20A measured by an acceleration sensor, a vibration sensor, or the like included in the sensor unit 24 described later.

[0045] The communication unit 23 has a DSP or the like, and realizes wireless communication or wired communication with another device (for example, the vehicle substitution simulation device 1) via the communication network 30 in compliance with standards such as LTE (Long Term Evolution), 4G (4th Generation), and 5G (5th Generation) and Wi-Fi (registered trademark). The communication unit 23 is used, for example, to transmit identification information (terminal ID), position information 221, vibration information 222, and speed information 223 of the mobile terminal 20A to the vehicle substitution simulation device 1 from the mobile terminal 20A side. In addition, the communication unit 23 may transmit new position information, time information, vibration information, speed information, etc. to the vehicle substitution simulation device 1 each time it acquires such information, or may transmit the newly accumulated position information, time information, vibration information, speed information, etc. together to the vehicle substitution simulation device 1 every predetermined time period (e.g., one minute, etc.). Furthermore, there is no particular restriction on the data exchanged between the communication unit 23 and other devices, and information other than the above information may be exchanged.

[0046] The sensor unit 24 is composed of, for example, a GPS sensor, an acceleration sensor, a vibration sensor, etc. The sensor unit 24 measures the moving speed and vibration of the mobile terminal 20A using the acceleration sensor, the vibration sensor, etc. The sensor unit 24 also receives a GPS satellite signal by the GPS sensor, measures the position information (latitude and longitude) of the mobile terminal 10, and acquires time information when the position information is measured.

[0047] The display unit 25 is configured with a display device such as a liquid crystal display or an organic electroluminescence panel. The display unit 25 displays an image upon receiving an instruction from the control unit 21. Examples of information displayed by the display unit 25 include user interfaces according to various application programs installed in the mobile terminal 20A.

[0048] The input unit 26 is composed of input devices such as physical switches called a numeric keypad and a touch panel superimposed on the display surface of the display unit 25. By outputting a signal based on an operation input from the input unit 26, for example, pressing the numeric keypad by the user or touching the touch panel, to the control unit 21, a selection operation by the user can be realized.

[0049] In addition, although not shown, the mobile terminal 20A may also be provided with a speaker, a microphone, etc. In this way, information may be output by voice from the speaker, and various selections and instructions by the user input by voice via the microphone may be input to the control unit 21 by voice recognition technology.

[0050] Next, the control unit 21 will be described in detail. The control unit 21 is composed of a microprocessor having a CPU, RAM, ROM, I / O, etc. The CPU executes each program read from the ROM or storage unit 22, and during execution, reads information from the RAM, ROM, and storage unit 22, writes information to the RAM and storage unit 22, and transmits and receives signals to and from the communication unit 23, the sensor unit 24, the display unit 25, and the input unit 26. In this way, the processing in this embodiment is realized by the cooperation of the hardware and software (programs).

[0051] The information transmission unit 211 transmits the position information 221, the vibration information 222, the speed information 223, and the like of the mobile terminal 20A to the vehicle substitution simulation device 1 by wireless communication using the communication unit . In addition, when the information transmission unit 211 receives an instruction for a simulation process from a user via the input unit 26 to the vehicle substitution simulation device 1, it transmits the terminal ID (identification information) of the mobile terminal 20A required for the simulation process, a specified period (for example, a certain day), and the specified electric vehicle type to the vehicle substitution simulation device 1 along with the instruction for the simulation process.

[0052] The result receiving unit 212 receives the results of the simulation process performed by the vehicle substitution simulation device 1 via the communication unit 23, and displays the received results of the simulation process on the display unit 25. FIG. 5 is a diagram showing an example of a display of the results of the simulation process. As shown in FIG. 5, based on the driving history of the user driving vehicle 20 on September 17th, when the user switched to an electric vehicle and the SoC at the time of departure was 100%, the result receiving unit 212 displays, in a list form on the display unit 25, the simulation results of the SoC information at each of the intermediate locations of shopping mall A, restaurant B, and the user's home upon returning home. This allows users to easily understand how much power will be consumed at each stopover point if they switch from an internal combustion engine vehicle 20 to an electric vehicle, which can help alleviate users' concerns. The configuration of the mobile terminal 20A has been described above.

[0053] Next, the operation of this embodiment will be described with reference to the flowchart shown in Fig. 6. Fig. 6 is a flowchart showing a vehicle substitution simulation process by the vehicle substitution simulation device 1. Specifically, the process flow is illustrated in which the vehicle substitution simulation device 1 simulates SoC information for each stopover point when a user switches from an internal combustion engine vehicle 20 owned by a user to an electric vehicle and adopts a driving mode similar to that of the vehicle 20. When performing the above simulation for electric vehicles corresponding to a plurality of different vehicle types, vehicle models are selected one by one, and simulation processing is performed for the one vehicle model selected using the flowchart shown in FIG. 6. Once the simulation processing for that vehicle model is completed, the remaining vehicle models are selected one by one and similar processing is performed. This processing is repeated for all specified vehicle models, thereby making it possible to perform simulation processing for each of a plurality of different vehicle models.

[0054] In step S10, the vehicle substitution simulation device 1 (location information acquisition unit 110) acquires location information, time information, vibration information, speed information, etc. of the user's mobile terminal 20A, and stores the acquired location information, time information, vibration information, speed information, etc. in the memory unit 12 by linking it to the terminal ID of the mobile terminal 20A.

[0055] In step S11, the vehicle substitution simulation device 1 (ride information acquisition unit 111) receives an instruction for simulation processing, and reads out from the storage unit 12 the position information and the like of the mobile terminal 20A during a predetermined period that is the subject of the simulation processing in accordance with the received instruction.

[0056] In step S12, the vehicle substitution simulation device 1 (ride information acquisition unit 111) excludes position information of movements other than those of the vehicle 20 from the position information of the mobile terminal 20A for the predetermined period read in step S11.

[0057] In step S13, when the change in location information indicating that the user's state is only "riding in a vehicle" is within a predetermined range (e.g., a radius of 500 m) for a predetermined period of time (e.g., 30 minutes or 1 hour) or more, the vehicle substitution simulation device 1 (ride information acquisition unit 111) determines that the user of the mobile terminal 20A is staying at a facility such as a restaurant, park, shopping mall, etc., and acquires the facility as route information.

[0058] In step S14, the vehicle substitution simulation device 1 (ride information acquisition unit 111) calculates the travel distance between each of the stopover points from the transition of the position information only when the user's state is "riding in the vehicle", and acquires it as travel distance information.

[0059] In step S15, the vehicle substitution simulation device 1 (SoC calculation unit 112) acquires electric vehicle performance information (battery capacity, average electricity consumption, charging time (normal charging), and charging time (fast charging)) corresponding to the electric vehicle type to be simulated from the electric vehicle information storage unit 123.

[0060] In step S16, when the user switches from the vehicle 20 to an electric vehicle, the vehicle substitution simulation device 1 (SoC calculation unit 112) calculates the remaining amount of power of the electric vehicle for each stopover point as SoC information.

[0061] In step S17, the vehicle substitution simulation device 1 (output unit 113) outputs the SoC information for each route point calculated in step S17 to the mobile terminal 20A via the communication network 30, and ends the simulation process.

[0062] As a result, it is possible to easily grasp the SoC information for each route point from the transition of the location information of the mobile terminal 20A (vehicle 20) within a predetermined period, assuming that the user changes his / her internal combustion engine vehicle 20 to an electric vehicle corresponding to the desired vehicle type and adopts the same driving mode as the vehicle 20. In this way, it is possible to provide the user with objective information when considering replacing the internal combustion engine vehicle 20 with an electric vehicle.

[0063] Each of the devices can be realized by hardware, software, or a combination of these. In addition, the navigation method performed by the cooperation of each of the devices included in the navigation system can also be realized by hardware, software, or a combination of these. Here, "realized by software" means that it is realized by a computer reading and executing a program.

[0064] The program can be stored and provided to the computer using various types of non-transitory computer readable media. The non-transitory computer readable media includes various types of tangible storage media. Examples of the non-transitory computer readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROM (Read Only Memory), CD-R, CD-R / W, and semiconductor memory (e.g., mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (random access memory)). The program may also be provided to the computer by various types of transitory computer readable media. Examples of the transitory computer readable media include electric signals, optical signals, and electromagnetic waves. The transitory computer readable media can provide the program to the computer via a wired communication path such as an electric wire and an optical fiber, or via a wireless communication path.

[0065] The above-described embodiment is a preferred embodiment of the present invention, but the scope of the present invention is not limited to the above-described embodiment, and the present invention can be implemented in various modified forms without departing from the gist of the present invention.

[0066] <Variation 1> In the above embodiment, the vehicle substitution simulation device 1 is realized by one server device or the like, but the functions of the vehicle substitution simulation device 1 may be distributed to a plurality of server devices as appropriate to form a distributed processing system. Also, the functions of the vehicle substitution simulation device 1 may be realized by using a virtual server function or the like on a cloud.

[0067] <Variation 2> In the above embodiment, the SoC value for each route point calculated by the vehicle substitution simulation device 1 is a positive value, but this is not limited to this. For example, the vehicle substitution simulation device 1 may end the simulation process when the SoC value becomes "0%" (out of power) and output the simulation result to the mobile terminal 20A. In this way, based on the result displayed on the mobile terminal 20A, the user can know which route points the user can go to without charging if they switch to an electric vehicle, and which route points they need to charge at. Alternatively, the vehicle substitution simulation device 1 may perform a simulation process to calculate the SoC at all stopover points even if the SoC value is a negative value, and output the simulation result to the mobile terminal 20A. In this way, based on the result displayed on the mobile terminal 20A, the user can know how much power consumption will be required before returning home if the user replaces the vehicle with an electric vehicle, how many times charging will be required, and at which stopover points charging will be required.
