Description

【Technical Field】 【0001】 The present invention relates to a mobile support technology for a mobile body having a function of charging the battery mounted thereon by traveling on a charging lane. 【Background Art】 【0002】 Conventionally, with the spread of battery electric vehicles (BEVs) or hybrid vehicles, there has been a problem of congestion in charging lanes, and there has been a driving support device that promotes efficient use of charging lanes (see Patent Document 1). 【Prior Art Documents】 【Patent Documents】 【0003】 【Patent Document 1】 Japanese Patent Application Laid-Open No. 2021-196689 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 However, conventionally, there has been no technology for promoting appropriate use of charging lanes. More specifically, conventionally, for example, there has been no technology regarding the use of charging lanes that aims to prevent deterioration of the battery of a mobile body. 【0005】 In view of such problems, the present invention aims to suppress charging that accelerates battery deterioration and prevent congestion caused by excessive use of charging lanes. 【Means for Solving the Problems】 【0006】 The first mobility support device of the present invention comprises: a detection unit that detects the existence of a charging lane on or around the path through which a mobile body is traveling, which can supply power to the mobile body by passing through it; an SOC acquisition unit that acquires SOC information indicating the charge status of the mobile body's battery; a determination unit that, when the detection unit detects the existence of a charging lane, determines recommendation information indicating whether to recommend or discourage the use of the charging lane based on the SOC information; and an output unit that outputs the recommendation information. 【0007】 This configuration allows for proper use of charging lanes while preventing battery degradation in the mobile device. 【0008】 Furthermore, the mobility support device of this second invention is a mobility support device that, compared to the first invention, further comprises an environment acquisition unit that acquires environmental information relating to the environment in which the mobile body moves, and a determination unit that determines recommendation information using the environmental information as well. 【0009】 This configuration allows for more efficient use of charging lanes while preventing battery degradation in the mobile device. 【0010】 Furthermore, the mobility support device of this third invention is a mobility support device that, compared to the first or second invention, further comprises an external acquisition unit that acquires external information relating to the power supply outside the mobile body, and a determination unit that determines recommendation information using the external information as well. 【0011】 This configuration allows for more efficient use of charging lanes while preventing battery degradation in the mobile device. 【0012】 Furthermore, the mobility support device of this fourth invention is a mobility support device in which, with respect to any one of the first to third inventions, the determination unit determines recommendation information which is non-recommendation information indicating that the use of the charging lane is not recommended. 【0013】 This configuration allows for the output of discouragement information to prevent battery degradation in the mobile device. 【0014】 Furthermore, the mobility support device of this fifth invention, compared to the fourth invention, is a mobility support device in which the determination unit determines recommendation information that is not recommended information when the recommendation condition is met, which is that the SOC information is equal to or greater than a first percentage value or greater than a first percentage. 【0015】 This configuration allows for the output of discouragement information to prevent battery degradation in the mobile device. 【0016】 Furthermore, the mobility support device of the sixth invention is a mobility support device in which, with respect to any one of the first to third inventions, the determination unit determines recommendation information, which is recommendation information recommending the use of a charging lane, when the recommendation condition that the SOC information is less than or equal to the second percentage value is met. 【0017】 This configuration allows for the output of appropriate recommendation information. 【0018】 Furthermore, the mobility support device of the seventh invention is a mobility support device in which, with respect to any one of the first to sixth inventions, the determination unit determines recommendation information when the recommendation conditions regarding power consumption and SOC information according to the distance between the current position of the moving object and a specific point are met. 【0019】 This configuration allows for the output of appropriate recommendation information. 【0020】 Furthermore, the mobility support device of the eighth invention, compared to the seventh invention, includes a location information acquisition unit that acquires location information indicating the current location, a destination acquisition unit that acquires destination information indicating the destination of the moving object, a calculation unit that calculates the distance from the current location to the destination and calculates the power consumption consumed over that distance based on the location information and destination information, and a determination unit that determines recommendation information, which is non-recommendation information indicating that the use of the charging lane is not recommended if the SOC information is less than a first percentage value and greater than or equal to a second percentage value, and the power consumption is less than the remaining power obtained from the SOC information. 【0021】 This configuration allows for the output of appropriate recommendation information. 【0022】 In addition, for the mobile support device of the ninth invention, for any one of the first to eighth inventions, when the output unit meets the recommendation conditions, the output unit outputs recommendation information, and the recommendation conditions vary according to the type of the mobile body. This is the mobile support device. 【0023】 With such a configuration, the charging lane can be used more appropriately based on the appropriate recommendation conditions according to the type of the mobile body. 【Advantages of the Invention】 【0024】 According to the mobile support device of the present invention, it is possible to suppress charging that accelerates battery deterioration and prevent congestion caused by excessive use of the charging lane. 【Brief Description of the Drawings】 【0025】 [Figure 1] Conceptual diagram of the mobile support system A in Embodiment 1 [Figure 2] Block diagram of the mobile support device 1 [Figure 3] Flowchart for explaining an operation example of the mobile support device 1 [Figure 4] Flowchart for explaining the first example of the recommendation information determination process [Figure 5] Flowchart for explaining the second example of the recommendation information determination process [Figure 6] Diagram showing the recommendation information management table [Figure 7] Diagram showing an example of the screen [Figure 8] Diagram showing an example of the screen [Figure 9] Diagram showing an example of the screen [Figure 10] Overview diagram of the computer system [Figure 11] Block diagram of the computer system 【Modes for Carrying Out the Invention】 【0026】 The embodiments of the mobility support device, etc., will be described below with reference to the drawings. In the embodiments, components that are denoted by the same reference numerals perform the same operation, and therefore, further explanation may be omitted. 【0027】 (Embodiment 1) In this embodiment, a mobility support device that provides recommendations regarding the use of a charging lane when the battery's SOC information matches the recommendation conditions will be described. 【0028】 Furthermore, in this embodiment, we will describe a mobility support device that makes recommendations regarding the use of charging lanes, for example, by utilizing environmental information such as weather, temperature, and time of day. 【0029】 Furthermore, in this embodiment, we will describe a mobility support device that makes recommendations regarding the use of charging lanes by utilizing external information such as information regarding the state of power shortage and the amount of stored energy at home. 【0030】 Furthermore, in this embodiment, a mobility support device with different recommendation conditions depending on the type of mobile object will be described. 【0031】 In this embodiment, the association of information X with information Y means that information Y can be obtained from information X, or information X can be obtained from information Y, and the method of association is not limited. Information X and information Y may be linked, may exist in the same buffer, may information X be contained in information Y, or information Y may be contained in information X, and so on. 【0032】 Figure 1 is a conceptual diagram of the mobility support system A in this embodiment. The mobility support system A comprises a mobile body B and a charging lane C. The mobile body B comprises a mobility support device 1, a battery 2, and a charging unit 3. 【0033】 Mobile object B could be, for example, a car or a motorcycle, but any vehicle that travels on a charging lane is acceptable, regardless of its type. 【0034】 The charging unit 3 draws electricity from the charging lane C and charges the battery 2. The charging unit 3 is used for wireless power transfer. The charging unit 3 includes, for example, a receiving coil 31 and a power conversion unit 32. Since the charging unit 3 can be realized using known technology, a detailed explanation is omitted. Furthermore, the method of wireless power transfer here is not limited to electromagnetic induction or magnetic resonance. 【0035】 The charging lane C is a travel lane for charging the battery 2 of the mobile vehicle B. The charging lane C includes, for example, a power transmission coil C1 and a power transmission conversion unit C2. Since the charging lane C can be realized using publicly known technology, a detailed explanation is omitted. The charging lane C may also be called, for example, a wireless power supply lane during travel. 【0036】 Figure 2 is a block diagram of the mobility support device 1 in this embodiment. The mobility support device 1 comprises a storage unit 11, a location information acquisition unit 12, a control unit 13, and an output unit 14. The control unit 13 comprises a detection unit 131, an environment acquisition unit 132, an external acquisition unit 133, a destination acquisition unit 134, a SOC acquisition unit 135, a calculation unit 136, and a determination unit 137. 【0037】 The memory unit 11, which constitutes the mobility support device 1, stores various types of information. These types of information include, for example, recommendation conditions, recommendation information (described later), detection conditions (described later), location information, environmental information, external information, destination information, SOC information, map information, and type information. The recommendation conditions in the memory unit 11 may be customized by the user. The recommendation conditions may also be associated with type information. Furthermore, it is preferable that the recommendation information or the source information from which the recommendation information is derived is associated with the recommendation conditions. 【0038】 The map information includes, for example, lane location information that identifies the location of charging lane C. The map information is, for example, a device used in a navigation system (not shown). The mobility support device 1 may also have a so-called navigation function. 【0039】 Type information refers to information that identifies the type of mobile vehicle B. Examples of type information include "BEV" for electric vehicles and "HC" for hybrid vehicles. 【0040】 The location information acquisition unit 12 acquires location information indicating the current location. The location information acquisition unit 12 typically acquires location information indicating the current location of the moving object B. The location information may be, for example, (latitude, longitude) or (latitude, longitude, altitude), but any information that identifies the current location is acceptable. 【0041】 The control unit 13 performs various processes. These various processes include, for example, those performed by the detection unit 131, the environment acquisition unit 132, the external acquisition unit 133, the destination acquisition unit 134, the SOC acquisition unit 135, the calculation unit 136, and the determination unit 137. 【0042】 The control unit 13, for example, receives recommendation conditions and stores them in the storage unit 11. This process makes it possible to customize the recommendation conditions for each mobility support device 1. 【0043】 The control unit 13, for example, receives destination information, searches for a route, acquires route information, and stores the route information in the storage unit 11. In other words, the control unit 13 implements, for example, a navigation function. 【0044】 The detection unit 131 detects that a charging lane C exists on or near the path through which the mobile body B is traveling. The charging lane C is a travel lane through which power can be supplied to the mobile body B as it passes. 【0045】 The path along which mobile object B travels is, for example, the path from the current location of mobile object B to the destination. The path along which mobile object B travels is, for example, the road on which mobile object B is traveling. The path along which mobile object B travels is, for example, the path from the current location of mobile object B to the destination. 【0046】 The area surrounding the path traveled by mobile object B is, for example, a point within or closer to a threshold from any point on the path from mobile object B's current location to its destination. The threshold can be, for example, 1 km, 500 m, etc., and is not limited to any specific value. The threshold can also be, for example, a value representing the travel time (e.g., 5 minutes). 【0047】 The detection unit 131 detects, for example, that a charging lane C exists on the path of the moving object B, and that it is within or less than a threshold distance from the current position. Note that the distance may be a physical distance or a temporal distance. 【0048】 The detection unit 131, for example, refers to the map information in the storage unit 11 and uses the lane position information contained in the map information to determine whether or not a charging lane C exists on the path from the current position of the moving object B to its destination. 【0049】 The detection unit 131, for example, refers to the map information in the storage unit 11 and uses the lane position information contained in the map information to determine whether or not a charging lane C exists on the path that the moving object B is traveling on, and at a distance within or less than a threshold from the current position. 【0050】 The detection unit 131, for example, refers to the map information in the storage unit 11 and uses the lane position information contained in the map information to determine whether or not a charging lane C exists within or below a threshold distance from the current location. The area within or below a threshold distance from the current location can be said to be the vicinity of the path that the moving object B is traveling. 【0051】 The detection unit 131 receives, for example, a presence signal from a transmitting device (not shown) indicating the presence of a charging lane C nearby. In this way, the detection unit 131 may detect the presence of a charging lane C on or around the path of the mobile body B. The transmitting device may be, for example, a beacon, but is not limited to that. 【0052】 The detection unit 131 detects the existence of the charging lane C, for example, when the current location and the location where the charging lane C exists satisfy the detection conditions. 【0053】 The detection conditions are the conditions for detecting charging lane C. For example, the detection conditions are: "The lane is on the path that moving object B is traveling on, and is within a threshold (e.g., 50m) from the location information indicating the current location," and "The lane is within a threshold (e.g., 100m) from the location information indicating the current location." 【0054】 The environmental information acquisition unit 132 acquires environmental information related to the environment in which the mobile body B is moving. Environmental information includes, for example, weather, temperature, and time of day. 【0055】 The environment acquisition unit 132 acquires, for example, the weather and temperature at the location where the mobile object B is moving. In this case, the environment acquisition unit 132 analyzes, for example, a camera and the images acquired by the camera to acquire the weather (e.g., "sunny," "rainy," etc.). The environment acquisition unit 132 also acquires the temperature outside the mobile object B using, for example, a temperature sensor. Furthermore, the environment acquisition unit 132 receives, for example, the weather and temperature at the current location indicated by location information from a server (not shown). 【0056】 The environment acquisition unit 132 acquires the current time from, for example, a clock (not shown) or an external server (not shown) (for example, an NTP server). 【0057】 The external acquisition unit 133 acquires external information regarding the power supply outside of the mobile unit B. This external information includes, for example, emergency information and energy storage information. 【0058】 Urgent information refers to information regarding the power shortage in the relevant country (e.g., "Japan") or region (e.g., "Kanto" or "Hyogo Prefecture"). Urgent information may include, for example, "Power is in a crunch (ON)", "Power is not in a crunch (OFF)", or "Degree of crunch." 【0059】 Energy storage information refers to information about the amount of energy stored at the user's home in mobile device B. This information includes, for example, the amount of energy stored, information indicating whether the amount of energy stored is above a certain threshold, and information indicating whether the amount of energy stored is below a certain threshold. 【0060】 The external acquisition unit 133 receives urgent information from, for example, a server or beacon (not shown). The external acquisition unit 133 also receives energy storage information from, for example, an energy storage device (not shown) at the home of the user of mobile body B. 【0061】 The destination acquisition unit 134 acquires destination information indicating the destination of the mobile body B. The destination acquisition unit 134 acquires destination information received by the mobility support device 1. The mobility support device 1, for example, receives destination information from the user. The mobility support device 1, for example, receives destination information from a terminal (not shown) owned by the user. The destination acquisition unit 134, for example, acquires destination information from the storage unit 11. 【0062】 The SOC acquisition unit 135 acquires the SOC information of the battery 2 of the mobile unit B. SOC information is information indicating the charge state of the battery 2. SOC information is information related to State of Charge (SOC). SOC information is, for example, the charge rate, but it may also be the amount of remaining power, whether the charge rate is above a threshold, whether the charge rate is below a threshold, etc. Note that the SOC acquisition unit 135 can be implemented using publicly known technology, so a detailed explanation is omitted. 【0063】 The calculation unit 136 calculates the distance from the current location to the destination based on the location information and destination information. Next, the calculation unit 136 uses the calculated distance to calculate the power consumption consumed for traveling that distance. Note that the process of calculating the power consumption for traveling that distance from the distance is a known technique, so a detailed explanation is omitted. 【0064】 The decision unit 137 determines recommendation information based on the SOC information acquired by the SOC acquisition unit 135. For example, when the detection unit 131 detects the presence of charging lane C, the decision unit 137 determines recommendation information based on the SOC information acquired by the SOC acquisition unit 135. 【0065】 Recommendation information refers to information indicating whether or not the use of charging lane C is recommended. Information recommending the use of charging lane C will be referred to as recommendation information, and information indicating that the use of charging lane C is not recommended will be referred to as non-recommendation information. 【0066】 Furthermore, determining the recommendation information can be done by obtaining the recommendation information itself, or by obtaining information that identifies the selected recommendation information (for example, the recommendation information ID). 【0067】 The decision unit 137 preferably determines recommendation information, which is non-recommendation information indicating that the use of charging lane C is not recommended. This prevents battery degradation due to excessive use of charging lanes and congestion of charging lanes. 【0068】 The decision unit 137 determines recommendation information, for example, when the SOC information acquired by the SOC acquisition unit 135 satisfies the recommendation conditions. The decision unit 137 also determines recommendation information, for example, when the detection unit 131 detects the presence of charging lane C and the SOC information acquired by the SOC acquisition unit 135 satisfies the recommendation conditions. 【0069】 The decision unit 137 determines, for example, that the recommendation condition is met when the SOC information is equal to or greater than the first percentage value or greater than the first percentage. 【0070】 The decision unit 137 determines the recommendation information, which is the recommended information, when it satisfies the recommendation condition, for example, that the SOC information is less than or equal to the second percentage value. 【0071】 The determination unit 137 determines recommendation information, for example, when it satisfies recommendation conditions regarding power consumption and SOC information based on the distance between the current location of the mobile object B and a specific point. The current location of the mobile object B is usually information acquired by the location information acquisition unit 12. The power consumption is usually information acquired by the calculation unit 136. 【0072】 The specific location refers to, for example, the location indicated by the destination information acquired by the destination acquisition unit 134, or the location indicated by the home information stored in the storage unit 11. 【0073】 The determination unit 137 determines, for example, recommendation information, which is non-recommended information, when the SOC information is less than the first percentage value and greater than or equal to the second percentage value, and the power consumption is less than the remaining power obtained from the SOC information. 【0074】 It is preferable for the determination unit 137 to determine recommendation information using one or more environmental information acquired by the environmental acquisition unit 132. In other words, it is preferable that the recommendation conditions differ depending on environmental information such as weather, temperature, time of day, and time of day. 【0075】 The decision unit 137, for example, when the weather acquired by the environment acquisition unit 132 is "rainy," sets a smaller threshold value for SOC information used to determine the recommendation information compared to the case of "sunny." In other words, the decision unit 137 will not recommend the use of the charging lane even if the SOC information is smaller when the weather is "rainy," compared to the case of "sunny." 【0076】 The determination unit 137, for example, if the outside temperature acquired by the environment acquisition unit 132 is between a first threshold (e.g., 30 degrees Celsius) and a second threshold (e.g., 10 degrees Celsius), compares this to cases where the outside temperature is higher than the first threshold or lower than the second threshold, and sets the threshold value for SOC information used to determine the recommendation information to a smaller value. In other words, for example, when the outside temperature is such that air conditioning is not needed, the determination unit 137 will not recommend the use of the charging lane even if the SOC information is smaller compared to when the outside temperature is hot or cold enough to require air conditioning. This is because power consumption is reduced when air conditioning is not used. 【0077】 The decision unit 137, for example, sets a lower threshold for SOC information used to determine recommendation information during periods when electricity prices are high compared to periods when prices are low. In other words, the decision unit 137 will not recommend the use of charging lanes even if the SOC information is smaller during periods when electricity prices are high compared to periods when prices are low. 【0078】 It is preferable for the decision unit 137 to determine the recommendation information using one or more external pieces of information acquired by the external acquisition unit 133. In other words, for example, it is preferable that the recommendation conditions differ depending on the external information. 【0079】 For example, if the urgent information indicates that the power situation in the world is urgent, the decision unit 137 determines the recommendation information if the urgent information is a smaller SOC value compared to the normal case. 【0080】 The decision unit 137, for example, if the urgent information indicates that the power situation is critical, will determine the recommendation information, which is non-recommended information, even if the urgent information is a smaller SOC value compared to the normal case. In other words, when the power situation is critical, it is preferable to determine non-recommended information rather than recommendation information whenever possible. 【0081】 The decision unit 137 may use different recommendation conditions depending on the type of mobile body B. Different recommendation conditions include, for example, different first percentage values ​​or second percentage values ​​as described above. 【0082】 It is preferable for the determination unit 137 to obtain type information that identifies the type of mobile body B from the storage unit 11, obtain recommendation conditions that correspond to the type information from the storage unit 11, and determine recommendation information if the recommendation conditions are met. 【0083】 The output unit 14 outputs the recommendation information determined by the determination unit 137. It is preferable for the output unit 14 to output the recommendation information when it matches the recommendation conditions. 【0084】 Here, "output" is a concept that includes display on a screen, projection using a projector, printing with a printer, sound output, transmission to an external device, storage on a recording medium, and transfer of processing results to other processing devices or other programs. 【0085】 The memory unit 11 is preferably made of a non-volatile recording medium, but it can also be made of a volatile recording medium. 【0086】 The process by which information is stored in the storage unit 11 is irrelevant. For example, information may be stored in the storage unit 11 via a recording medium, information transmitted via a communication line or the like may be stored in the storage unit 11, or information input via an input device may be stored in the storage unit 11. 【0087】 The location information acquisition unit 12 is implemented, for example, by a GPS receiver. However, the location information acquisition unit 12 may also be implemented by other means of acquiring location information. 【0088】 The control unit 13, detection unit 131, environment acquisition unit 132, external acquisition unit 133, destination acquisition unit 134, SOC acquisition unit 135, calculation unit 136, and determination unit 137 can be implemented, for example, by a processor or memory. The processing procedures of the control unit 13, etc., are usually implemented in software, and this software is recorded on a recording medium such as ROM. However, it may also be implemented in hardware (dedicated circuitry). The processor can be a CPU, MPU, GPU, etc., and the type is not limited. 【0089】 The environment acquisition unit 132 and the external acquisition unit 133 may be implemented using wireless or wired communication means. 【0090】 The output unit 14 may or may not include output devices such as a display or speakers. The output unit 14 can be implemented using driver software for the output device, or using driver software for the output device and the output device itself. 【0091】 Next, an example of the operation of the mobility support device 1, which constitutes the mobility support system A, will be explained using the flowchart in Figure 3. 【0092】 (Step S301) The detection unit 131 determines whether or not it has detected a charging lane C on or around the path along which the moving body B is traveling. If a charging lane C is detected, the process proceeds to step S302; otherwise, the process returns to step S301. 【0093】 (Step S302) The SOC acquisition unit 135 acquires the SOC information of the battery 2. 【0094】 (Step S303) The decision unit 137 performs a process to determine the recommendation information. An example of such a recommendation information determination process will be explained using the flowcharts in Figures 4 and 5. 【0095】 (Step S304) The output unit 14 outputs one or more recommendation pieces obtained in step S303. The process ends. 【0096】 In the flowchart of Figure 3, the mobility support device 1 performed the recommendation information determination process after detecting charging lane C. However, in the flowchart of Figure 3, the mobility support device 1 may also perform the process of detecting charging lane C when the SOC information, etc., matches the recommendation conditions. Alternatively, the mobility support device 1 may output recommendation information without detecting charging lane C. This is a useful process, for example, when charging lane C cannot be detected due to a malfunction of the communication device or deterioration of the communication environment. 【0097】 Next, we will explain the first example of the recommendation information determination process in step S303 using the flowchart in Figure 4. 【0098】 (Step S401) The determination unit 137 obtains type information from the storage unit 11. 【0099】 (Step S402) The decision unit 137 obtains one or more recommendation conditions from the storage unit 11 that correspond to the type information obtained in step S401. 【0100】 (Step S403) The determination unit 137 assigns 1 to counter i. 【0101】 (Step S404) The decision unit 137 determines whether or not the i-th recommendation condition exists among the recommendation conditions obtained in step S402. If the i-th recommendation condition exists, the process proceeds to step S405; otherwise, the process returns to the higher level. 【0102】 (Step S405) The decision unit 137 obtains the i-th recommendation condition. 【0103】 (Step S406) The environment acquisition unit 132 determines whether the i-th recommendation condition is a condition based on environmental information. If the i-th recommendation condition is a condition based on environmental information, the process goes to step S407; otherwise, the process goes to step S408. 【0104】 (Step S407) The environment acquisition unit 132 acquires one or more environmental information items to be used in the i-th recommendation condition. 【0105】 (Step S408) The external information acquisition unit 133 determines whether the i-th recommendation condition is a condition based on external information. If the i-th recommendation condition is a condition based on external information, the process goes to step S409; otherwise, the process goes to step S410. 【0106】 (Step S409) The external acquisition unit 133 acquires one or more external pieces of information to be used in the i-th recommendation condition. 【0107】 (Step S410) The determination unit 137 determines whether the acquired SOC information, or the acquired SOC information and one or more environmental information, or the acquired SOC information and one or more external information, or the acquired SOC information, one or more environmental information, and one or more external information satisfies the i-th recommendation condition. If the i-th recommendation condition is met, the process proceeds to step S411; otherwise, the process proceeds to step S412. 【0108】 (Step S411) The decision unit 137 obtains recommendation information corresponding to the i-th recommendation condition. 【0109】 (Step S412) The determination unit 137 increments the counter i by 1. Return to step S404. 【0110】 Next, a second example of the recommendation information determination process in step S303 will be explained using the flowchart in Figure 5. 【0111】 (Step S501) The determination unit 137 determines whether the acquired SOC information is equal to or greater than the first percentage value or greater than the first percentage value. If the recommendation conditions are met, the process proceeds to step S507; otherwise, the process proceeds to step S502. The recommendation conditions here are usually that the SOC information is equal to or greater than the first percentage value and less than or equal to 100%. 【0112】 (Step S502) The determination unit 137 determines whether the acquired SOC information is equal to or greater than the second percentage value. If the recommendation conditions are met, the process proceeds to step S503; otherwise, the process proceeds to step S508. 【0113】 The recommendation criteria here are that the SOC information is less than or equal to the first percentage value, and greater than or equal to the second percentage value. Furthermore, the recommendation criteria for proceeding to step S508 are that the SOC information is less than or equal to the second percentage value, and greater than or equal to 0%. 【0114】 (Step S503) The position information acquisition unit 12 acquires position information indicating the current position of the mobility support device 1. 【0115】 (Step S504) The destination acquisition unit 134 acquires destination information. The destination information is received by the mobility support device 1 and stored in the storage unit 11. 【0116】 (Step S505) The calculation unit 136 uses the location information obtained in step S503 and the destination information obtained in step S504 to calculate the distance from the current location to the destination. Next, the calculation unit 136 uses the calculated distance to calculate the power consumption consumed for travel that distance. 【0117】 (Step S506) The determination unit 137 obtains the remaining power from the acquired SOC information. Next, the determination unit 137 determines whether the condition "power consumption < remaining power" is met. If the condition is met, proceed to step S507; otherwise, proceed to step S508. 【0118】 Note that the condition here is not necessarily "power consumption < remaining power," but could also be "power consumption + α (where α is a positive constant) < remaining power," which allows for a little margin or takes into account power consumption errors. 【0119】 (Step S507) The decision unit 137 obtains the deprecation information. It returns to the higher-level processing. 【0120】 (Step S508) The decision unit 137 obtains the recommendation information. It returns to the higher-level processing. 【0121】 The following describes specific examples of the operation of the mobility support device 1 that constitutes the mobility support system A in this embodiment. 【0122】 Currently, the memory unit 11 of the mobility support device 1 owned by user A's mobile device B stores the recommendation information management table shown in Figure 6. The recommendation information management table is a table that manages recommendation information corresponding to recommendation conditions. The recommendation information management table manages one or more records that have "ID", "Type information", "Recommendation conditions", and "Recommendation information". The "Recommendation conditions" have "SOC information (S)", "Environmental information", and "External information". The "Environmental information" has "Weather", "Temperature", and "Time of day". The "External information" has "Urgency information" and "Energy storage information". The "Recommendation information" here can be either recommended information or non-recommended information. Recommended information is, for example, "There is a 'charging lane' XXm ahead. There is sufficient capacity, so please refrain from entering the charging lane." Non-recommended information is, for example, "There is a 'charging lane' XXm ahead. There is sufficient power to reach your destination, so please refrain from entering the charging lane." 【0123】 In Figure 6, the record with "ID=1" represents a case where the recommendation conditions are the same regardless of the type information of mobile object B. The record with "ID=1" has recommendation conditions based on SOC information. 【0124】 The record with "ID=2" in Figure 6 shows cases where the recommendation conditions differ depending on whether the type information of mobile body B is "BEV" or "HC". The record with "ID=2" has recommendation conditions based on SOC information, environmental information, and external information. 【0125】 The recommendation condition for the first row corresponding to the record type information "BEV" for "ID=2" is "SOC information <= 80% AND weather = rain". The recommendation condition for the second row corresponding to the record type information "BEV" for "ID=2" is "SOC information <= 80% AND urgent information = ON". Note that "urgent information = ON" is information indicating that it is urgent. The recommendation condition for the third row corresponding to the record type information "BEV" for "ID=2" is "SOC information <= 80% AND energy storage information >= threshold". The recommendation condition for the first row corresponding to the record type information "HC" for "ID=2" is "SOC information <= 90% AND weather = rain AND temperature <= 30 degrees Time period = 9:00-18:00". Furthermore, the recommendation condition for the second row corresponding to the record type information "HC" for "ID=2" is "SOC information <= 90% AND money storage information >= threshold". 【0126】 It should be assumed that the storage unit 11 of the mobility support device 1 stores information about the type of the mobile object B. 【0127】 Furthermore, the memory unit 11 stores the detection condition "the moving object B is on the path it is traveling on and within 50m of the location information indicating its current location." 【0128】 Furthermore, the mobility support device 1 is said to have a navigation function. The memory unit 11 of the mobility support device 1 stores destination information indicating the destination received from the user. The memory unit 11 also stores route information that identifies the route indicated by the current location information and the destination information. 【0129】 Furthermore, the memory unit 11 stores the recommendation condition "ID=1" selected by the user. 【0130】 In this situation, let's assume that User A has started driving vehicle B. Furthermore, let's assume that the navigation function of the mobility support device 1 is operational, and that map information and the current location are displayed on the display of the mobility support device 1. 【0131】 The detection unit 131 of the mobility support device 1 acquires detection conditions from the storage unit 11. Then, while the mobile body B is moving, the detection unit 131 continuously refers to the map information in the storage unit 11 and performs the process of detecting a charging lane C at a point on the path indicated by the path information and within 50m of the current location information, and finally determines that the charging lane C has been detected. 【0132】 Next, the SOC acquisition unit 135 acquires the SOC information of the battery 2 (in this case, "charge rate = 65%"). 【0133】 Next, the decision unit 137 refers to the recommendation condition "ID=1" in Figure 6 and obtains the condition "Power Consumption < Remaining Power" which corresponds to "Charge Rate = 65%". 【0134】 Next, the SOC acquisition unit 135 acquires the remaining power (RP) from the "charge rate = 65%" and the power when the storage unit 11 is at 100% charge rate. 【0135】 Furthermore, the calculation unit 136 calculates the distance between the current location information and the destination information. Next, the calculation unit 136 uses this distance to calculate the power consumption (CP). 【0136】 Next, it is assumed that the determination unit 137 determines that "CP < RP". Next, the determination unit 137 determines that it meets the recommendation condition on the second line of "ID = 1" in FIG. 6. Then, it acquires the recommendation information "non-recommended information" that pairs with the recommendation condition on the second line of "ID = 1" in FIG. 6. Next, the determination unit 137 acquires the information that is the basis of the non-recommended information in the storage unit 11, "There is a 'charging lane' 50 m ahead. Since there is sufficient power to reach the destination, please refrain from entering the charging lane.", substitutes "50" for "XX", and constructs the non-recommended information. 【0137】 Next, the output unit 14 outputs the acquired recommendation information, which is the non-recommended information, to the navigation screen. An example of such a screen is FIG. 7. In FIG. 7, 70 is the display of the mobile support device 1. 71 is the destination, 72 is an example display of the non-recommended information, 73 is the charging lane C, 74 is the current location, and 75 indicates the lane to be traveled from the current location to the location of the charging lane C. 【0138】 As described above, in this specific example, the mobile support device 1 can appropriately present non-recommended information to the user using the SOC information. By doing so, it is possible to suppress charging that accelerates battery degradation and prevent congestion of the charging lane C due to excessive use. 【0139】 In this specific example, it is assumed that the SOC information acquired by the SOC acquisition unit 135 is "charging rate = 85%". Then, the determination unit 137 detects that it meets the recommendation condition on the first line of "ID = 1" in FIG. 6. And the determination unit 137 acquires the non-recommended information. Next, the output unit 14 outputs the acquired recommendation information, which is the non-recommended information, to the navigation screen. An example of such a screen is FIG. 8. In FIG. 8, 80 is the display of the mobile support device 1. 81 is the destination, 82 is an example display of the non-recommended information, 83 is the charging lane C, 84 is the current location, and 85 indicates the lane to be traveled from the current location to the location of the charging lane C. 【0140】 Furthermore, in this specific example, let's assume that the SOC information acquired by the SOC acquisition unit 135 was "charge rate = 15%". Then, the decision unit 137 detects that it matches the recommendation condition in the third row of "ID=1" in Figure 6. The decision unit 137 then acquires the recommendation information that corresponds to the recommendation condition in the third row. Next, the output unit 14 outputs the acquired recommendation information to the navigation screen. An example of such a screen is shown in Figure 9. In Figure 9, 90 is the display of the mobility support device 1. 91 is the destination, 92 is an example of the display of recommendation information, 93 is charging lane C, 94 is the current location, and 95 shows the route from the current location to charging lane C. 【0141】 As described above, according to this embodiment, it is possible to properly utilize the charging lane while preventing battery degradation of the mobile device. 【0142】 Furthermore, according to this embodiment, non-recommended information can be output to prevent battery degradation of the mobile device. 【0143】 Furthermore, according to this embodiment, appropriate recommendation information can be output. 【0144】 Furthermore, according to this embodiment, charging lanes can be utilized more effectively by using appropriate recommendation conditions according to the type of mobile object. 【0145】 The processing in this embodiment may be implemented by software. This software may be distributed by software download or the like. Alternatively, this software may be recorded on a recording medium such as a CD-ROM and distributed. This also applies to other embodiments in this specification. The software that implements the mobility support device 1 in this embodiment is the following program.
