Description

[Technical Field]

[0001] The present disclosure relates to a tire management system and a tire management method. [Background technology]

[0002] A system is known that can issue an alarm indicating that a pneumatic tire (hereinafter simply referred to as a "tire") mounted on a vehicle such as an automobile is punctured when it is determined that the tire is punctured (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-6266 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, if it is determined that the tire is punctured, the safety of the vehicle can be ensured if the vehicle can be guided to a nearby stopping place such as a gas station or convenience store.

[0005] However, in a configuration in which the destination stopping location is determined regardless of the size of the vehicle, if the vehicle is a large vehicle such as a semi-trailer, the destination may be determined to be a stopping location that does not have a stopping space where the vehicle can be parked.

[0006] An object of the present disclosure is to provide a tire management system and a tire management method that can guide a vehicle to a parking location appropriate for the size of the vehicle when an abnormality occurs in the tire. [Means for solving the problem]

[0007] A tire management system according to one aspect of the present disclosure includes an acquisition processing unit, a detection processing unit, and a first output processing unit. The acquisition processing unit acquires status information related to the status of pneumatic tires mounted on a vehicle. The detection processing unit detects an abnormality in the pneumatic tires based on the status information acquired by the acquisition processing unit. When the abnormality is detected by the detection processing unit, the first output processing unit outputs first route information including a first route to a specific stop location having a stopping space according to the size of the vehicle from among a plurality of predetermined stop locations to an output destination corresponding to the vehicle.

[0008] With this configuration, when a tire abnormality is detected, it is possible to inform the driver of the vehicle of a route to a specific stop location that has a stop space appropriate for the size of the vehicle, thereby guiding the vehicle to a stop location appropriate for the size of the vehicle. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Note that the following embodiments are examples that embody the present disclosure and do not limit the technical scope of the present disclosure.

[0012] [First embodiment] First, with reference to FIG. 1, the configuration of a tire management system 100 according to a first embodiment of the present disclosure will be described.

[0013] As shown in FIG. 1, the tire management system 100 includes a vehicle 1, a communication device 2, a terminal device 3, and a management server 4.

[0014] In the tire management system 100, a management server 4 is connected to a communication device 2 and a terminal device 3 via a communication network such as the Internet or a LAN (Local Area Network) so as to be able to communicate with each other.

[0015] The vehicle 1 is an automobile fitted with pneumatic tires 11 (hereinafter simply referred to as "tires") that are subject to management by the tire management system 100. For example, the vehicle 1 is a combination vehicle made up of a tractor 7 (see FIG. 1) and a trailer 8 (see FIG. 1) towed by the tractor 7. The combination vehicle is generally called a semi-trailer or the like. The vehicle 1 may be a tractor or a trailer. The vehicle 1 may also be a truck crane, a truck, a bus, a passenger car, or the like.

[0016] The vehicle 1 is equipped with a plurality of tires 11 (see FIG. 1). FIG. 1 shows six tires 11 that the vehicle 1 has. Of the six tires 11, tire 11A is mounted on a wheel located at the front wheel position on the left side of the tractor 7. Tire 11B is mounted on a wheel located at the front wheel position on the right side of the tractor 7. Tire 11C is mounted on a wheel located at the rear wheel position on the left side of the tractor 7. Tire 11D is mounted on a wheel located at the rear wheel position on the right side of the tractor 7. Tire 11E is mounted on a wheel located at the rear wheel position on the left side of the trailer 8. Tire 11F is mounted on a wheel located at the rear wheel position on the right side of the trailer 8. The number of tires 11 on the vehicle 1 is not limited to six.

[0017] As shown in FIG. 1, a vehicle 1 includes a plurality of detection devices 12 corresponding to a plurality of tires 11. Of the plurality of detection devices 12, detection device 12A is provided in tire 11A. Furthermore, detection device 12B is provided in tire 11B. Furthermore, detection device 12C is provided in tire 11C. Furthermore, detection device 12D is provided in tire 11D. Furthermore, detection device 12E is provided in tire 11E. Furthermore, detection device 12F is provided in tire 11F.

[0018] The detection device 12 includes an air pressure detection unit that detects the air pressure and air temperature in the tire 11 on which the detection device 12 is provided. The air pressure detection unit includes a pressure sensor, a temperature sensor, and the like.

[0019] The detection device 12 also includes a communication unit used for wireless communication with the in-vehicle communication device 13 (see FIG. 1). The communication unit includes a transmitter, an antenna, and the like.

[0020] Specifically, the detection device 12 performs wireless communication according to a predetermined first wireless communication standard with an in-vehicle communication device 13 that is present within a communication range of the detection device 12 for the first wireless communication standard. For example, the first wireless communication standard is IEEE, a well-known international standard, or a wireless communication standard that complies with IEEE. For example, the first wireless communication standard is Bluetooth (registered trademark) or Wi-Fi (registered trademark). In this case, the detection device 12 can perform wireless communication with an in-vehicle communication device 13 that is present within a range of several tens of meters. Note that the first wireless communication standard may be a standard different from Bluetooth or Wi-Fi.

[0021] The detection device 12 transmits status data to the wirelessly connected in-vehicle communication device 13. The status data includes detection device identification information used to identify the detection device 12, air pressure information indicating the air pressure in the tire 11 detected by the air pressure detection unit, and air temperature information indicating the air temperature in the tire 11 detected by the air pressure detection unit. The air pressure information and the air temperature information are each a type of status information relating to the status of the tire 11 mounted on the vehicle 1.

[0022] For example, the detection device 12 executes a detection process and a transmission process at a predetermined execution cycle. The detection process is a process of detecting the air pressure and air temperature of the tire 11 using the air pressure detection unit. The transmission process is a process of transmitting the status data including the detection results of the detection process to the in-vehicle communication device 13. For example, the execution cycle is a time period arbitrarily set between 10 seconds and 10 minutes.

[0023] The detection device 12 may include an acceleration sensor, instead of the air pressure detection unit or together with the air pressure detection device, that detects acceleration in the rotational direction, the rotational axis direction, and the radial direction of the tire 11. In this case, the status data may include acceleration information that indicates the acceleration of the tire 11 in three directions detected by the acceleration sensor. The acceleration information is a type of status information regarding the status of the tire 11 mounted on the vehicle 1.

[0024] Furthermore, the detection device 12 may execute the detection process and the transmission process when receiving a predetermined control signal transmitted from the management server 4 via the communication device 2 and the in-vehicle communication device 13.

[0025] The vehicle 1 includes an on-board communication device 13 (see FIG. 1). The on-board communication device 13 is provided at a position where it can perform wireless communication with each of the detection devices 12 in accordance with the first wireless communication standard.

[0026] The in-vehicle communication device 13 receives the status data transmitted from the detection device 12 .

[0027] Furthermore, the in-vehicle communication device 13 acquires location information indicating the current location of the vehicle 1. For example, the in-vehicle communication device 13 includes a GPS receiver capable of receiving radio waves transmitted from a GPS satellite. The in-vehicle communication device 13 acquires the location information based on information contained in the radio waves received by the GPS receiver.

[0028] Furthermore, the in-vehicle communication device 13 performs wireless communication according to a predetermined second wireless communication standard with a communication device 2 (see FIG. 1) that exists within a communication range of the in-vehicle communication device 13 according to the second wireless communication standard. For example, the second wireless communication standard is LTE (registered trademark). In this case, the in-vehicle communication device 13 can perform wireless communication with a communication device 2 that exists within a range of several kilometers. Note that the second wireless communication standard may be a standard different from LTE.

[0029] The in-vehicle communication device 13 transmits the status data received from the detection device 12 to the wirelessly connected communication device 2. Specifically, the in-vehicle communication device 13 adds additional data to the status data received from the detection device 12, and transmits the status data with the added additional data to the communication device 2. The additional data includes communication device identification information used to identify the in-vehicle communication device 13, the location information, and reception date and time information indicating the date and time when the status data was received.

[0030] The in-vehicle communication device 13 also includes a display unit used to display information output from the management server 4.

[0031] The communication device 2 receives the status data transmitted from the in-vehicle communication device 13. The communication device 2 may be provided at any location.

[0032] 1, the communication device 2 includes an antenna 21. The antenna 21 is used for wireless communication with an in-vehicle communication device 13. The communication device 2 performs wireless communication according to the second wireless communication standard between the antenna 21 and the in-vehicle communication device 13 that is present within the communication range of the second wireless communication standard.

[0033] Furthermore, when the communication device 2 receives the status data from the in-vehicle communication device 13, the communication device 2 transmits the received status data to the management server 4.

[0034] The terminal device 3 is an information processing device used by an employee of a road service provider. Here, road service is a service in which, when a vehicle has trouble, a service rushes to the current location of the vehicle to resolve the trouble. For example, the terminal device 3 is a personal computer installed in a call center of the provider. Note that the terminal device 3 may also be a smartphone or tablet terminal used by the employee of the provider.

[0035] The management server 4 executes various processes related to the management of the tires 11 based on the condition data.

[0036] [Administration Server 4 Configuration] Next, the configuration of the management server 4 will be described with reference to FIG.

[0037] As shown in FIG. 2, the management server 4 includes a control unit 31, a communication unit 32, and a storage unit 33.

[0038] The control unit 31 comprehensively controls the management server 4. As shown in FIG. 2, the control unit 31 includes a CPU 41, a ROM 42, and a RAM 43. The CPU 41 is a processor that executes various types of arithmetic processing. The ROM 42 is a non-volatile storage device that stores in advance information such as control programs for causing the CPU 41 to execute various types of processing. The RAM 43 is a volatile or non-volatile storage device that is used as a temporary storage memory (work area) for the various types of processing executed by the CPU 41. In the control unit 31, the CPU 41 executes the various control programs that are pre-stored in the ROM 42. In this way, the management server 4 is comprehensively controlled by the control unit 31.

[0039] The communication unit 32 is a communication interface that can perform wired or wireless data communication with an external communication device such as the communication device 2 via the communication network.

[0040] The storage unit 33 is a nonvolatile storage device, such as a flash memory, a nonvolatile memory such as an EEPROM (registered trademark), a solid state drive (SSD), or a hard disk drive (HDD).

[0041] The memory unit 33 stores vehicle information corresponding to each vehicle 1 registered in advance in the management server 4. The vehicle information is information about the vehicle 1. The vehicle information includes information such as the type, size, weight, color, and vehicle registration number of the vehicle 1. The vehicle information also includes vehicle identification information used to identify the vehicle 1, the communication device identification information of the on-board communication device 13 provided in the vehicle 1, and the detection device identification information of the detection device 12 corresponding to each tire 11 mounted on the vehicle 1. The vehicle information also includes tire information corresponding to each tire 11 mounted on the vehicle 1. The tire information is information about the tire 11. The tire information includes information such as the type, size, and manufacturing timing of the tire 11.

[0042] The storage unit 33 also stores map information including a map of a predetermined specific area. The specific area is a region or country where the vehicle 1 is used. The map includes roads that are passable by automobiles.

[0043] The storage unit 33 also stores road identification information used to identify specific roads corresponding to predetermined specific vehicles among the roads included in the map. The specific vehicles are vehicles whose size and / or weight exceed predetermined standards and whose traversable roads are restricted. The specific roads are roads designated in advance as roads traversable by the specific vehicles. For example, the specific roads are expressways.

[0044] The memory unit 33 also stores stopping place information corresponding to each stopping place registered in advance in the management server 4. The stopping place is a place within the specific area that has a stopping space where a vehicle can be parked. For example, the stopping place may be a gas station, a service station, a highway parking area, a highway rest area, a convenience store, a parking lot at a commercial facility such as a shopping mall, a rental parking lot such as a pay parking lot, an automobile dealership, or an automobile repair shop. The stopping place information is information related to the stopping place. The stopping place information includes information such as the name, address, telephone number, size of the stopping space, and number of the stopping spaces of the stopping place.

[0045] 2, the storage unit 33 includes six data storage units 51. The six data storage units 51 are provided for each vehicle 1 registered in the management server 4 in advance.

[0046] Of the six data storage units 51, data storage unit 51A is a storage area of ​​the memory unit 33 used to store the condition data corresponding to tire 11A. Data storage unit 51B is a storage area of ​​the memory unit 33 used to store the condition data corresponding to tire 11B. Data storage unit 51C is a storage area of ​​the memory unit 33 used to store the condition data corresponding to tire 11C. Data storage unit 51D is a storage area of ​​the memory unit 33 used to store the condition data corresponding to tire 11D. Data storage unit 51E is a storage area of ​​the memory unit 33 used to store the condition data corresponding to tire 11E. Data storage unit 51F is a storage area of ​​the memory unit 33 used to store the condition data corresponding to tire 11F.

[0047] Here, according to the tire management system 100 of the first embodiment of the present disclosure, if an abnormality occurs in the tire 11, it is possible to guide the vehicle 1 to the parking location according to the size of the vehicle 1.

[0048] Specifically, the control unit 31 includes a storage processing unit 61, an acquisition processing unit 62, a detection processing unit 63, a first output processing unit 64, a second output processing unit 65, and a third output processing unit 66 shown in Fig. 2. For example, the control unit 31 functions as the storage processing unit 61, the acquisition processing unit 62, the detection processing unit 63, the first output processing unit 64, the second output processing unit 65, and the third output processing unit 66 by executing a tire management program stored in advance in the memory unit 33. Note that some or all of the processing units included in the control unit 31 may be configured with electronic circuits. Furthermore, the tire management program may be a program for causing a plurality of processors to function as the various processing units.

[0049] When the storage processing unit 61 receives the status data transmitted from the communication device 2, it stores the received status data in one of the data storage units 51.

[0050] Specifically, the storage processing unit 61 determines one of the data storage units 51 as the storage destination for the status data based on the communication device identification information and the detection device identification information included in the received status data. Then, the storage processing unit 61 stores the received status data in the data storage unit 51 determined as the storage destination.

[0051] The acquisition processing unit 62 acquires the state information relating to the state of the tire 11 mounted on the vehicle 1 when a predetermined acquisition timing arrives.

[0052] For example, the acquisition timing is the timing when new status data is stored in the data storage unit 51. In this case, the acquisition processing unit 62 acquires the status information for the vehicle 1 whose status data is stored in the data storage unit 51.

[0053] For example, when the acquisition timing arrives, the acquisition processing unit 62 acquires the plurality of status data selected in order of the most recent reception date and time information from each of the data storage units 51 corresponding to the vehicle 1 .

[0054] The acquisition timing may be a timing that arrives at a predetermined cycle, or may be a timing when an instruction to acquire the status information is input to the management server 4 via an information processing device such as a personal computer that is communicably connected to the management server 4.

[0055] The acquisition processing unit 62 may also acquire the status information for some of the multiple tires 11 equipped on the vehicle 1. The acquisition processing unit 62 may also transmit the control signal to the detection device 12 of the vehicle 1 via the communication device 2 and the in-vehicle communication device 13, and acquire the status data transmitted from the detection device 12 in response to the input of the control signal.

[0056] The detection processing unit 63 detects an abnormality in the tire 11 based on the state information acquired by the acquisition processing unit 62 .

[0057] For example, the abnormality includes a first abnormality in which the air pressure of the tire 11 is outside a predetermined reference range, and a second abnormality in which the rate at which the air pressure of the tire 11 decreases exceeds a predetermined reference rate.

[0058] Specifically, the detection processing unit 63 determines the presence or absence of the first abnormality for each tire 11 based on the latest condition data acquired by the acquisition processing unit 62. For example, the detection processing unit 63 determines that the first abnormality exists when the air pressure information corrected based on the air temperature information is outside the reference range.

[0059] Furthermore, the detection processing unit 63 determines the presence or absence of the second abnormality for each tire 11 based on the plurality of pieces of condition data acquired by the acquisition processing unit 62. For example, the detection processing unit 63 determines that the second abnormality exists when the rate of decrease in the air pressure of the tire 11 calculated based on the plurality of pieces of condition data exceeds the reference rate.

[0060] If the condition data includes the acceleration information, the detection processing unit 63 may detect the abnormality based on the acceleration information. In this case, the abnormality includes a third abnormality in which the tire 11 vibrates in the axial or radial direction. The detection processing unit 63 also determines the presence or absence of the third abnormality based on the acceleration information.

[0061] The detection processing unit 63 may also detect the abnormality in some of the plurality of tires 11 provided on the vehicle 1.

[0062] When the abnormality is detected by the detection processing unit 63, the first output processing unit 64 outputs first route information including a first route to a specific stopping location among the multiple stopping locations that has the stopping space according to the size of the vehicle 1 to an output destination corresponding to the vehicle 1.

[0063] For example, the first output processing unit 64 outputs the first route information including the first route from the current position of the vehicle 1 to the specific stop that is located within a predetermined first specific distance.

[0064] For example, the first specified distance is a distance arbitrarily determined between 1 kilometer and 50 kilometers. Note that the first specified distance may be a distance determined based on one or more of the type and degree of the detected abnormality and the weight of the vehicle 1.

[0065] Specifically, the first output processing unit 64 selects the specific stop location from a plurality of stop locations previously registered in the management server 4 based on the vehicle information and the stop location information. For example, the first output processing unit 64 selects the specific stop location based on size information of the vehicle 1 included in the vehicle information and size information of the stop space included in the stop location information. Alternatively, the first output processing unit 64 may select the specific stop location based on information related to the size of the vehicle 1 included in the vehicle information and size information of the stop space included in the stop location information. For example, the first output processing unit 64 may select the specific stop location based on type information of the vehicle 1 included in the vehicle information and size information of the stop space included in the stop location information. In this case, the first output processing unit 64 may determine the size of the vehicle 1 based on the type information of the vehicle 1 included in the vehicle information and size information corresponding to each type of vehicle 1 (e.g., passenger car, light car) previously stored in the storage unit 33. Furthermore, the information related to the size of the vehicle 1 included in the vehicle information may be weight information or a classification number included in the vehicle registration number. That is, the specific stopping location may be selected based on rough dimensions that are previously associated with the vehicle type or weight of the vehicle 1. Furthermore, the first output processing unit 64 selects the specific stopping location that is present within the range of the first specific distance from the current position of the vehicle 1 based on the position information added to the status data used to detect the abnormality.

[0066] Then, the first output processing unit 64 determines one of the selected specific stop locations as the specific stop location to be output.

[0067] Specifically, if the selected specific stop locations include an establishment that can provide a maintenance service to address the abnormality that occurs in the tire 11, the first output processing unit 64 determines the establishment closest to the current location of the vehicle 1 as the specific stop location to be output. For example, the establishment may be a gas station, a service station, a car dealership, or an auto repair shop. The maintenance service to address the first abnormality is an air pressure adjustment service to adjust the air pressure of the tire 11. The maintenance service to address the second abnormality is a tire change service to change the tire 11. The maintenance service to address the third abnormality is a vehicle inspection service to inspect the vehicle 1.

[0068] Furthermore, if the business establishment is not included in the selected specific stop locations, the first output processing unit 64 determines the specific stop location closest to the current position of vehicle 1 as the specific stop location to be output. Furthermore, if the specific stop location does not exist within the range of the first specific distance from the current position of vehicle 1, the first output processing unit 64 outputs a message to that effect to the output destination corresponding to vehicle 1.

[0069] Note that, when the selected specific stop places include the business office, the first output processing unit 64 may determine the business office having the largest stopping space available for stopping vehicle 1 as the specific stop place to be output. Furthermore, when the selected specific stop places do not include the business office, the first output processing unit 64 may determine the specific stop place having the largest stopping space available for stopping vehicle 1 as the specific stop place to be output. Furthermore, regardless of whether the selected specific stop places include the business office, the first output processing unit 64 may determine the specific stop place that is closest to the current position of vehicle 1 or has the largest stopping space available for stopping vehicle 1 as the specific stop place to be output. Furthermore, regardless of whether the specific stop place is located within the first specific distance from the current position of vehicle 1, the first output processing unit 64 may determine the specific stop place that is closest to the current position of vehicle 1 as the specific stop place to be output.

[0070] When the first output processing unit 64 determines the specific stop to be output, it acquires the first route to the specific stop based on the map information. Then, the first output processing unit 64 determines any one of the acquired one or more first routes as the first route to be output.

[0071] Here, if the vehicle 1 is not the specified vehicle, the first output processing unit 64 determines, as the first route to be output, the first route with the shortest travel distance to the specified stop location to be output, from among the one or more acquired first routes. The determination of whether the vehicle 1 is the specified vehicle is performed based on the vehicle information.

[0072] Furthermore, when the vehicle 1 is the specified vehicle, the first output processing unit 64 determines, from among the one or more acquired first routes, a specific first route that passes through the specific road as the first route to be output. Specifically, the specific first route is a first route that passes only through the specific road. The specific road is identified based on the road identification information. When the one or more acquired first routes do not include the specific first route, the first output processing unit 64 outputs a message to that effect to the output destination corresponding to the vehicle 1. Note that the specific first route may also be the first route that passes through the specific road and has the shortest travel distance on a road other than the specific road.

[0073] In addition, the first output processing unit 64 may determine, as the first route to be output, the first route with the shortest travel distance to the specific stop location to be output, among the one or more first routes acquired, regardless of whether the vehicle 1 is the specific vehicle or not.

[0074] When the first route to be output is determined, the first output processing unit 64 outputs the first route information including the first route to an output destination corresponding to the vehicle 1.

[0075] For example, the first route information may be map information in which the first route to be output is identifiable. The first route information may include audio information for guiding the vehicle 1 to the specific stop to be output.

[0076] For example, the first output processing unit 64 outputs a message indicating that the abnormality has been detected and the first route information to a display unit of the in-vehicle communication device 13. The first output processing unit 64 may also send an email including the message indicating that the abnormality has been detected and the first route information to an email address associated with the vehicle 1 in advance.

[0077] When the specific stop location output by the first output processing unit 64 is not the business establishment, the second output processing unit 65 can output first notification information indicating that the abnormality has been detected and including the specific stop location to an output destination corresponding to the provider.

[0078] For example, the second output processing unit 65 outputs the first notification information when the vehicle in which the abnormality is detected is not the tractor 7. Furthermore, the second output processing unit 65 does not output the first notification information when the vehicle in which the abnormality is detected is the tractor 7.

[0079] The first notification information includes information such as that the abnormality has been detected, the time the abnormality was detected, a request for road service, the location of the specific stopping location, the expected time of arrival of vehicle 1 at the specific stopping location, and the type, size, color, and vehicle registration number of vehicle 1.

[0080] The second output processing unit 65 outputs the first notification information to the display unit of the terminal device 3.

[0081] The second output processing unit 65 may output the first notification information when the abnormality detected by the detection processing unit 63 is a predetermined specific abnormality. For example, the specific abnormality is the second abnormality. The second output processing unit 65 may also output the first notification information unconditionally when the specific stop location output by the first output processing unit 64 is not the business establishment.

[0082] When the specific stopping location output by the first output processing unit 64 is not the business establishment, when the vehicle 1 is the articulated vehicle, and when an abnormality is detected in the tire 11 mounted on the tractor 7, the third output processing unit 66 outputs second route information including a second route from the specific stopping location to the business establishment located within a predetermined second specific distance range to an output destination corresponding to the vehicle 1.

[0083] For example, the second specified distance is a distance arbitrarily determined between 1 kilometer and 20 kilometers. Note that the second specified distance may be a distance determined based on one or more of the type and degree of the detected abnormality, the weight of the tractor 7, and the distance traveled since the abnormality was detected.

[0084] For example, if the business establishment is located within the second specified distance from the specific stop, the third output processing unit 66 outputs the second route information including the second route from the specific stop to the closest business establishment. Furthermore, if the business establishment is not located within the second specified distance from the specific stop, the third output processing unit 66 outputs a message to that effect to an output destination corresponding to the vehicle 1. In this case, the third output processing unit 66 may output the first notification information to an output destination corresponding to the provider.

[0085] For example, the second route information is map information in which the second route to be output is displayed in a distinguishable manner, similar to the first route information.

[0086] For example, when the vehicle 1 arrives at the specific stopping location output by the first output processing unit 64, the third output processing unit 66 outputs a message urging the vehicle 1 to detach the trailer 8 from the tractor 7 at the specific stopping location, as well as the second route information, to the display unit of the in-vehicle communication device 13.

[0087] The control unit 31 does not necessarily have to include either or both of the second output processing unit 65 and the third output processing unit 66.

[0088] [First tire management process] 3, the tire management method of the present disclosure will be described below along with an example of the procedure of the first tire management process executed by the control unit 31 of the management server 4 in the tire management system 100. Here, steps S11, S12, etc. represent the numbers of the processing procedures (steps) executed by the control unit 31.

[0089] <Step S11> First, in step S11, the control unit 31 determines whether the acquisition timing has arrived. The process of step S11 is executed by the acquisition processing unit 62 of the control unit 31.

[0090] Here, when the control unit 31 determines that the acquisition timing has arrived (Yes in S11), it shifts the process to step S12. On the other hand, when the acquisition timing has not arrived (No in S11), the control unit 31 waits for the arrival of the acquisition timing in step S11.

[0091] <Step S12> In step S12, the control unit 31 acquires the state information. The process of step S12 is an example of an acquisition step of the present disclosure, and is executed by the acquisition processing unit 62 of the control unit 31.

[0092] <Step S13> In step S13, the control unit 31 determines whether or not the abnormality has been detected based on the status information acquired in step S12. The process of step S13 is an example of a detection step of the present disclosure, and is executed by the detection processing unit 63 of the control unit 31.

[0093] Here, if the control unit 31 determines that the abnormality has been detected (Yes in S13), the control unit 31 shifts the process to step S14. On the other hand, if the abnormality has not been detected (No in S13), the control unit 31 shifts the process to step S11.

[0094] <Step S14> In step S14, the control unit 31 outputs the first route information to an output destination corresponding to the vehicle 1. Here, the processing of step S14 is an example of an output step in the present disclosure, and is executed by the first output processing unit 64 of the control unit 31.

[0095] <Step S15> In step S15, the control unit 31 determines whether or not the specific stop included in the first route information output in step S14 is the business establishment.

[0096] Here, when the control unit 31 determines that the specific stop included in the first route information output in step S14 is the business office (Yes in S15), the control unit 31 shifts the process to step S11. On the other hand, when the specific stop included in the first route information output in step S14 is not the business office (No in S15), the control unit 31 shifts the process to step S16.

[0097] <Step S16> In step S16, the control unit 31 determines whether the vehicle in which the abnormality has been detected is the tractor 7 or not.

[0098] Here, when the control unit 31 determines that the vehicle in which the abnormality was detected is the tractor 7 (Yes in S16), the control unit 31 shifts the processing to step S17. On the other hand, when the vehicle in which the abnormality was detected is not the tractor 7 (No in S16), the control unit 31 shifts the processing to step S18.

[0099] <Step S17> In step S17, the control unit 31 outputs the second route information to an output destination corresponding to the vehicle 1. Here, the process of step S17 is executed by the third output processing unit 66 of the control unit 31.

[0100] <Step S18> In step S18, the control unit 31 outputs the first notification information to an output destination corresponding to the provider. The process of step S18 is executed by the second output processing unit 65 of the control unit 31.

[0101] In this way, in the tire management system 100, the status information regarding the status of the tire 11 mounted on the vehicle 1 is acquired, and the abnormality of the tire 11 is detected based on the acquired status information. Then, when the abnormality is detected, the first route information including the first route to the specific stopping place among the multiple stopping places that has the stopping space according to the size of the vehicle 1 is output to an output destination corresponding to the vehicle 1. As a result, when the abnormality is detected, it is possible to communicate to the driver of the vehicle 1, etc., the route to the specific stopping place that has the stopping space according to the size of the vehicle 1. Therefore, it is possible to guide the vehicle 1 to the stopping place according to the size of the vehicle 1.

[0102] Furthermore, in the tire management system 100, when the vehicle 1 is the specified vehicle, the first route information including the specified first route that passes through the specified road among the plurality of first routes is output. As a result, when the vehicle 1 in which the abnormality is detected is the specified vehicle, it is possible to communicate to the driver of the vehicle 1, etc., a route to the specified stopping location that passes through the specified road. Therefore, by defining a vehicle whose passable roads are limited to the specified road as the specified vehicle, when the abnormality is detected in the tire 11 of the specified vehicle, it is possible to guide the specified vehicle to the specified stopping location within the range of the pass restriction.

[0103] Furthermore, the tire management system 100 outputs the first route information including the first route from the current position of the vehicle 1 to the specific stop location that is within the first specific distance range from the current position of the vehicle 1. This makes it possible to guide the vehicle 1 in which the abnormality has been detected to the specific stop location that is within the first specific distance range from the vehicle 1.

[0104] Furthermore, in the tire management system 100, if the specific stop that is the business is located within the first specific distance from the current location of the vehicle 1, the first route information including the first route to the specific stop is output. Furthermore, if the specific stop that is the business does not exist, the first route information including the first route to the specific stop located within the first specific distance from the current location of the vehicle 1 is output. If the output specific stop is not the business, the first notification information indicating that the abnormality has been detected and including the specific stop can be output to an output destination corresponding to the provider. This makes it possible to guide the vehicle 1 to the business if the specific stop that is the business is located within the first specific distance from the current location of the vehicle 1 where the abnormality was detected. Furthermore, if the specific stop that is the business does not exist, it is possible to guide the vehicle 1 to the specific stop located within the first specific distance from the vehicle 1. Furthermore, when the vehicle 1 is guided to the specific stop that is not the business premises, it is possible to notify the provider that the abnormality has been detected in the tire 11 of the vehicle 1 and the specific stop to which the vehicle 1 is heading. This can save the driver of the vehicle 1, for example, the trouble of contacting the provider to resolve the abnormality in the tire 11.

[0105] Furthermore, in the tire management system 100, when the specific stopping location to be output is not the business establishment, when the vehicle 1 is the articulated vehicle, and when an abnormality is detected in the tire 11 mounted on the tractor 7, the second route information including the second route from the specific stopping location to the business establishment located within the second specific distance is output to an output destination corresponding to the vehicle 1. As a result, when the vehicle 1 is guided to the specific stopping location that is not the business establishment, when the vehicle 1 is the articulated vehicle, and when an abnormality is detected in the tire 11 of the tractor 7, it is possible to communicate to the driver of the vehicle 1, etc., the route from the specific stopping location to the business establishment located within the second specific distance. Therefore, it is possible to guide the tractor 7 that has been detached from the trailer 8 at the specific stopping location to the business establishment located within the second specific distance from the specific stopping location.

[0106] The vehicle 1 is not limited to an automobile, but may be anything that is equipped with tires 11. For example, the vehicle 1 may include a motorcycle, a three-wheeled vehicle, a moped, and the like.

[0107] Furthermore, the status information does not have to be limited to the air pressure information, the air temperature information, and the acceleration information. For example, the status information may include a photographed image of the surface of the tire 11. Furthermore, the abnormality does not have to be limited to the first abnormality, the second abnormality, and the third abnormality. For example, the abnormality may include an abnormality related to the wear state of the tire 11.

[0108] The tire management system 100 may also be capable of setting, as the specific stopping location, a location that is not a parking lot and that does not have facilities for providing maintenance services in response to the abnormality. Here, in this specification, a parking lot is a location off a road where a parking space can be identified by a border, a tire stopper, a partition, or the like. In other words, the parking lot in this specification does not include a location on a road. Furthermore, the parking lot in this specification does not include a location where a parking space cannot be identified, such as an empty lot.

[0109] Specifically, the tire management system 100 may be capable of setting a location on a road where no facility for providing maintenance services in response to the abnormality is installed as the specific stopping location. For example, locations on a road where no facility for providing maintenance services in response to the abnormality is installed include emergency parking lanes on expressways, time-restricted parking sections installed on roads, and road shoulders and side strips where parking and stopping are not prohibited. This increases the number of candidates for the specific stopping location compared to a configuration in which the specific stopping location is limited to either or both of a location (the business establishment) where facility for providing maintenance services in response to the abnormality is installed and a parking lot. This makes it possible to stop a vehicle 1 with the abnormality in a tire 11 more quickly.

[0110] Furthermore, among shoulders having the stopping space according to the size of vehicle 1, only shoulders that satisfy a predetermined first specific condition may be set as the specific stopping location. For example, the first specific condition may be that the width of the road including the shoulder is wider than a distance determined according to the size of vehicle 1. The first specific condition may be that the current traffic volume on the road including the shoulder is less than a predetermined volume. The first specific condition may be that the legal maximum speed on the road including the shoulder is lower than a predetermined speed. Furthermore, among shoulders having the stopping space according to the size of vehicle 1, only shoulders that satisfy a predetermined second specific condition may be set as the specific stopping location. The second specific condition may be the same as the first specific condition. The second specific condition may be that the width of the shoulder is wider than a distance determined according to the size of vehicle 1. By limiting the shoulders and sidewalks that can be set as the specific stopping location in this manner, the risk of a collision between vehicle 1 stopped at the specific stopping location and another vehicle can be reduced. Furthermore, it is possible to prevent congestion from occurring due to the vehicle 1 stopping at the specific stopping location.

[0111] [Second embodiment] Next, the configuration of a tire management system 200 according to a second embodiment of the present disclosure will be described with reference to FIGS.

[0112] 4, the tire management system 200 includes a vehicle 1, a communication device 2, a terminal device 3, and a management server 4. In the tire management system 200, the management server 4 is connected to the communication device 2 and the terminal device 3 via the communication network so that they can communicate with each other. The configurations of the vehicle 1 and the communication device 2 are the same as those of the tire management system 100.

[0113] The terminal device 3 is an information processing device used by an employee of the business establishment. For example, the terminal device 3 is a personal computer installed in the business establishment. The terminal device 3 may also be a smartphone or a tablet terminal used by an employee of the business establishment.

[0114] The management server 4 has the same configuration as the management server 4 of the tire management system 100, except that the contents stored in the memory unit 33 have been changed, and that the management server 4 includes a first determination processing unit 67, a fourth output processing unit 68, a second determination processing unit 69, and a fifth output processing unit 70 shown in Fig. 5 instead of the second output processing unit 65 and the third output processing unit 66. Only the configuration that differs from that of the management server 4 of the tire management system 100 will be described below.

[0115] In the tire management system 200, the stop location is the business establishment. Therefore, the stop location information stored in the memory unit 33 is information related to the business establishment. Specifically, the stop location information includes information such as the name, address, telephone number, size of the stop space, and number of stop spaces of the business establishment. The stop location information also includes business establishment identification information used to identify the business establishment, and inventory information of materials used for maintenance services at the business establishment. The materials include replacement tires 11, etc. The stop location information also includes terminal device identification information used to identify the terminal device 3.

[0116] After the first output processing unit 64 outputs the first route information, the first determination processing unit 67 determines whether the vehicle 1 is moving in accordance with the first route information.

[0117] For example, the first determination processing unit 67 determines that the vehicle 1 is moving according to the first route information when the movement of the vehicle 1 according to the first route information continues for more than a predetermined time. Note that the first determination processing unit 67 may also determine that the vehicle 1 is moving according to the first route information when the movement distance of the vehicle 1 according to the first route information exceeds a predetermined distance.

[0118] When the first output processing unit 64 outputs the first route information, the fourth output processing unit 68 can output second notification information containing that information to an output destination corresponding to the specific stop location included in the first route information (the specific stop location determined as the output target).

[0119] Specifically, when the first judgment processing unit 67 determines that the vehicle 1 is moving according to the first route information, the fourth output processing unit 68 outputs the second notification information to an output destination corresponding to the specific stop location included in the first route information.

[0120] The second notification information includes information such as that the first route information has been output, information such as the type, color, and size of vehicle 1, information indicating the type of abnormality, the current location of vehicle 1, and the estimated arrival time of vehicle 1.

[0121] When the first judgment processing unit 67 determines that the vehicle 1 is moving in accordance with the first route information, the fourth output processing unit 68 outputs the second notification information to the display unit of the terminal device 3 corresponding to the specific stop location included in the first route information.

[0122] When the first route information is output by the first output processing unit 64, the fourth output processing unit 68 may immediately output the second notification information to an output destination corresponding to the specific stop included in the first route information. In this case, the control unit 31 does not need to include the first determination processing unit 67.

[0123] When the first route information is output by the first output processing unit 64, the second determination processing unit 69 determines whether the material is present at the specific stop included in the first route information.

[0124] Specifically, when the maintenance service corresponding to the abnormality detected by the detection processing unit 63 is the tire replacement service, the second determination processing unit 69 determines whether or not the tires 11 required for the tire replacement service are in stock at the specific stop location included in the first route information. Based on the type and size of the tire 11 in which the abnormality was detected and the stop location information, the second determination processing unit 69 determines whether or not the tires 11 required for the tire replacement service are in stock at the specific stop location included in the first route information.

[0125] When the second determination processing unit 69 determines that the material is not available, the fifth output processing unit 70 outputs third notification information containing that information to an output destination corresponding to the specific business establishment that is closest to the location of the specific stop included in the first route information and that has the material.

[0126] The third notification information includes information such as that the second determination processing unit 69 has determined that the supplies are not available, information such as the name, address, and telephone number of the specific stop included in the first route information, and information for identifying the missing supplies.

[0127] The fifth output processing unit 70 determines one of the plurality of establishments as the specific establishment based on the stop location information.

[0128] Specifically, when the second notification information is output by the fourth output processing unit 68, the fifth output processing unit 70 outputs the third notification information to the display unit of the terminal device 3 corresponding to the specific establishment.

[0129] [Second tire management process] Hereinafter, an example of the procedure of the second tire management process executed by the control unit 31 of the management server 4 in the tire management system 200 will be described with reference to FIG.

[0130] <Step S21> First, in step S21, the control unit 31 determines whether the acquisition timing has arrived. The process of step S21 is executed by the acquisition processing unit 62 of the control unit 31.

[0131] Here, when the control unit 31 determines that the acquisition timing has arrived (Yes in S21), it shifts the process to step S22. On the other hand, when the acquisition timing has not arrived (No in S21), the control unit 31 waits for the arrival of the acquisition timing in step S21.

[0132] <Step S22> In step S22, the control unit 31 acquires the state information. The process of step S22 is executed by the acquisition processing unit 62 of the control unit 31.

[0133] <Step S23> In step S23, the control unit 31 determines whether or not the abnormality has been detected based on the state information acquired in step S22. The process of step S23 is executed by the detection processing unit 63 of the control unit 31.

[0134] Here, if the control unit 31 determines that the abnormality has been detected (Yes in S23), the control unit 31 shifts the process to step S24. On the other hand, if the abnormality has not been detected (No in S23), the control unit 31 shifts the process to step S21.

[0135] <Step S24> In step S24, the control unit 31 outputs the first route information to an output destination corresponding to the vehicle 1. Here, the processing of step S24 is executed by the first output processing unit 64 of the control unit 31.

[0136] <Step S25> In step S25, the control unit 31 determines whether the vehicle 1 is moving according to the first route information output in step S24. The process of step S25 is executed by the first determination processing unit 67 of the control unit 31.

[0137] Here, if the control unit 31 determines that the vehicle 1 is moving according to the first route information (Yes in S25), the control unit 31 shifts the process to step S26. On the other hand, if the vehicle 1 is not moving according to the first route information (No in S25), the control unit 31 shifts the process to step S21.

[0138] <Step S26> In step S26, the control unit 31 outputs the second notification information to an output destination corresponding to the specific stop included in the first route information. Here, the processing of step S26 is executed by the fourth output processing unit 68 of the control unit 31.

[0139] <Step S27> In step S27, the control unit 31 determines whether the material is present at the specific stop included in the first route information. The process of step S27 is executed by the second determination processing unit 69 of the control unit 31.

[0140] Here, when the control unit 31 determines that the material is present at the specific stop included in the first route information (Yes in S27), the control unit 31 shifts the process to step S21. On the other hand, when the control unit 31 determines that the material is not present at the specific stop included in the first route information (No in S27), the control unit 31 shifts the process to step S28.

[0141] <Step S28> In step S28, the control unit 31 outputs the third notification information to the output destination corresponding to the specific establishment. The process of step S28 is executed by the fifth output processing unit 70 of the control unit 31.

[0142] In this way, in the tire management system 200, the stopping place is the business establishment. As a result, when an abnormality occurs in the tire 11 of the vehicle 1, it is possible to guide the vehicle 1 to the business establishment that corresponds to the size of the vehicle 1.

[0143] Furthermore, in the tire management system 200, when the first route information is output, the second notification information including the first route information can be output to an output destination corresponding to the specific stop included in the first route information. This makes it possible to notify the employee at the specific stop included in the first route information in advance of the arrival of the vehicle 1. Therefore, it is possible to prepare to receive the vehicle 1 at the specific stop.

[0144] Furthermore, in the tire management system 200, after outputting the first route information, it is determined whether the vehicle 1 is moving according to the first route information. If it is determined that the vehicle 1 is moving according to the first route information, the second notification information is output to an output destination corresponding to the specific stop included in the first route information. This makes it possible to limit the opportunity to output the second notification information to when the vehicle 1 is moving according to the first route information. Therefore, it is possible to prevent waste of preparations for a visit to the specific stop included in the first route information.

[0145] Furthermore, when the tire management system 200 outputs the first route information, it determines whether the materials used in the maintenance service at the specific stop included in the first route information are present. If it is determined that the materials are not present, third notification information indicating this is output to an output destination corresponding to the specific business that is closest to the location of the specific stop included in the first route information and that has the materials. This makes it possible to notify employees at the specific business that there are shortages of the materials at the specific stop included in the first route information and encourage the employees to deliver the materials. This eliminates the need for employees at the specific stop included in the first route information to arrange for the missing materials.
