Description

TECHNICAL FIELD

[0001] The present disclosure relates to a tire air pressure management system and a tire air pressure management method. BACKGROUND

[0002] Known is a system that detects and outputs the air pressure of a pneumatic tire (hereinafter, simply referred to as "tire") mounted to a vehicle such as an automobile. For example, known is a system that outputs the air pressure of the tire of the vehicle detected at the time of engine ignition of the vehicle in the case where a predetermined output timing has come (see Patent Literature 1).

[0004] PATENT LITERATURE

[0005] Patent Literature 1: Japanese Patent Application Publication No. 2018-47849 SUMMARY

[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] However, in the case where a rental vehicle such as a rental automobile is returned, the air pressure of the tire of the rental vehicle is measured as one step of an inspection operation for the returned rental vehicle. Also, if the measured air pressure is not within a prescribed range, an adjustment operation of the air pressure of the tire is performed.

[0008] In the case where the rental vehicle is returned, if the air pressure of the tire of the rental vehicle at the time of return can be output, the work burden of the inspection operation for the rental vehicle can be reduced.

[0009] However, due to a temperature rise of the tire caused by running of the rental vehicle until the time of return, the air pressure of the tire of the rental vehicle at the time of return temporarily rises. Therefore, in the case where the rental vehicle is returned, in a structure in which the air pressure of the tire of the rental vehicle detected at the time of return is directly output, the determination of necessity or non-necessity of the adjustment operation of the air pressure of the tire can sometimes be erroneous.

[0010] An object of the present disclosure is to provide a tire air pressure management system and a tire air pressure management method that can reduce the work burden of an inspection operation for a vehicle.

[0011] MEANS FOR SOLVING THE PROBLEMS

[0012] The tire air pressure management system of one aspect of the present disclosure has an acquisition processing section, a correction processing section, and a first output processing section. The acquisition processing section acquires an air pressure of a pneumatic tire mounted on a vehicle and an air temperature inside the pneumatic tire. The correction processing section corrects the air pressure acquired together with the air temperature, according to a difference between the air temperature acquired by the acquisition processing section and a predetermined reference temperature. The first output processing section outputs determination information for determining whether or not air pressure adjustment of the pneumatic tire is required, based on the air pressure corrected by the correction processing section.

[0013] According to this structure, the determination information output is transmitted to a worker who performs an inspection work of the vehicle, whereby the worker can not have to perform an inspection work of the air pressure of the tire. Therefore, it is possible to reduce a work burden of the worker with respect to the inspection work of the vehicle.

[0014] Effects of Invention

[0015] According to the present disclosure, it is possible to reduce a work burden with respect to an inspection work of a vehicle. BRIEF DESCRIPTION OF DRAWINGS

[0027] The following is a reference to the appendix. Figure 1 The embodiments of this disclosure will be described below. Furthermore, the following embodiments are merely examples embodying this disclosure and do not limit the technical scope of this disclosure.

[0028] [First Implementation]

[0029] First, refer to Figure 1 The structure of the tire pressure management system 100 according to the first embodiment of this disclosure will be described.

[0030] like Figure 1 As shown, the tire pressure management system 100 includes a vehicle 1, a first communication device 2, a terminal device 3, and a management server 4.

[0031] In the tire pressure management system 100, the management server 4 is connected to the first communication device 2 and the terminal device 3 in a manner that enables them to communicate with each other via a communication network such as the Internet or LAN (local area network).

[0032] Vehicle 1 is a rental vehicle rented to a pre-determined user. For example, Vehicle 1 is a rental car rented by a car rental company. Alternatively, Vehicle 1 could be a shared car rented by a car-sharing service provider, etc.

[0033] Vehicle 1 is rented out at a pre-determined location by the car rental operator and returned to that location. That is, the location is both the rental location and the return location for Vehicle 1. Alternatively, the rental location for Vehicle 1 may be a different location than the return location.

[0034] like Figure 1As shown, the vehicle 1 is provided with four pneumatic tires 11 (hereinafter, simply referred to as "tires"). A tire 11A among the four tires 11 is attached to a wheel at a front wheel position on the left side of the vehicle 1. Also, a tire 11B is attached to a wheel at a front wheel position on the right side of the vehicle 1. Also, a tire 11C is attached to a wheel at a rear wheel position on the left side of the vehicle 1. Also, a tire 11D is attached to a wheel at a rear wheel position on the right side of the vehicle 1.

[0035] As shown, the vehicle 1 is provided with four pneumatic tires 11 (hereinafter, simply referred to as "tires"). A tire 11A among the four tires 11 is attached to a wheel at a front wheel position on the left side of the vehicle 1. Also, a tire 11B is attached to a wheel at a front wheel position on the right side of the vehicle 1. Also, a tire 11C is attached to a wheel at a rear wheel position on the left side of the vehicle 1. Also, a tire 11D is attached to a wheel at a rear wheel position on the right side of the vehicle 1. Figure 1

[0036] The pneumatic pressure detection device 12 is provided with a sensor that detects the pneumatic pressure and the air temperature within the tire 11 in which the pneumatic pressure detection device 12 is provided. Also, the pneumatic pressure detection device 12 is provided with a transmitter and an antenna that transmit the detection result of the sensor to the outside. The pneumatic pressure detection device 12 is an example of the detection unit of the present disclosure.

[0037] Specifically, the pneumatic pressure detection device 12 performs wireless communication in accordance with a first wireless communication standard with a first communication device 2 (refer to FIG. 1) that exists within a communication range of the first wireless communication standard from the pneumatic pressure detection device 12. For example, the first wireless communication standard is IEEE, which is known as an international standard, or a wireless communication standard that conforms to IEEE. For example, the first wireless communication standard is Bluetooth or Wi-Fi, or the like. In this case, the pneumatic pressure detection device 12 is able to perform wireless communication with the first communication device 2 that exists within a range of several meters. Note that the first wireless communication standard can also be a standard other than Bluetooth or Wi-Fi. Figure 1

[0038] The pneumatic pressure detection device 12 transmits detection data that contains the detection result of the sensor to the first communication device 2. The detection data contains detection device identification information for identification of the pneumatic pressure detection device 12, pneumatic pressure information that indicates the pneumatic pressure within the tire 11 detected by the sensor, air temperature information that indicates the air temperature within the tire 11 detected by the sensor, and the like.

[0039] ​​For example, in a case where wireless communication in accordance with the first wireless communication standard can be performed with the first communication device 2, the air pressure detection device 12 performs a detection process and a transmission process at a predetermined execution cycle. The detection process is a process of detecting the air pressure and the air temperature of the tire 11 using the sensor. The transmission process is a process of transmitting the detection data including the detection result of the detection process to the first communication device 2. For example, the execution cycle is an arbitrary time determined from 10 seconds to 10 minutes. In addition, the air pressure detection device 12 can also perform the detection process and the transmission process in a case where an execution instruction is received from the management server 4 via the first communication device 2.

[0040] The first communication device 2 receives the detection data transmitted from the air pressure detection device 12 and transmits the received detection data to the management server 4. The first communication device 2 is provided at each of the business offices. The first communication device 2 is an example of the communication section of the present disclosure.

[0041] As shown in Figure 2 , the first communication device 2 includes a first antenna 21. The first antenna 21 is used for wireless communication with the air pressure detection device 12. The first communication device 2 performs wireless communication in accordance with the first wireless communication standard with the air pressure detection device 12 existing within a communication range of the first wireless communication standard from the first antenna 21.

[0042] In a case where the detection data is received from the air pressure detection device 12, the first communication device 2 attaches first attached data to the received detection data. Also, the first communication device 2 transmits the detection data to which the first attached data is attached to the management server 4. The first attached data includes reception date and time information indicating the reception date and time of the detection data, business office identification information for identification of the business office, and the like.

[0043] The terminal device 3 is an information processing device used by the employee of the business office. For example, the terminal device 3 is a personal computer provided at the business office. In addition, the terminal device 3 can also be a smartphone or a tablet terminal or the like used by the employee of the business office.

[0044] The management server 4 performs various processes related to the management of the air pressure of the tire 11 based on the detection data.

[0045] [Structure of Management Server 4]

[0046] Next, the structure of the management server 4 will be described with reference to Figure 2 .

[0047] As shown in Figure 2As shown, the management server 4 includes a control unit 31, a communication unit 32, and a storage unit 33.

[0048] Control Department 31 Integrated Control Management Server 4. (e.g.) Figure 2 As shown, the control unit 31 includes a CPU 41, a ROM 42, and a RAM 43. The CPU 41 is a processor that performs various arithmetic operations. The ROM 42 is a non-volatile storage device that stores information such as control programs for the CPU 41 to perform various operations. The RAM 43 is a volatile or non-volatile storage device used as temporary storage (working area) for the various operations performed by the CPU 41. In the control unit 31, the CPU 41 executes various control programs that are stored in the ROM 42. Thus, the management server 4 is comprehensively controlled by the control unit 31.

[0049] The communication unit 32 is a communication interface that can perform wired or wireless data communication with external communication devices such as the first communication device 2 via the communication network.

[0050] Storage unit 33 is a non-volatile storage device. For example, storage unit 33 is a non-volatile memory such as flash memory and EEPROM, a storage device such as SSD (Solid State Drive) and HDD (Hardware Disc Drive).

[0051] The storage unit 33 pre-stores vehicle information corresponding to each vehicle 1. This vehicle information is related to vehicle 1. The vehicle information includes vehicle identification information for identifying vehicle 1, vehicle registration number, vehicle type, color, and size, identification information of the tire pressure monitoring devices 12 corresponding to each tire 11 installed on vehicle 1, and tire information corresponding to each tire 11 installed on vehicle 1. The tire information is related to each tire 11. The tire information includes tire type, size, and manufacturing date.

[0052] In addition, such as Figure 2 As shown, the storage unit 33 includes four data storage units 51. The four data storage units 51 are configured according to the vehicle identification information pre-registered in the management server 4.

[0053] Of the four data storage units 51, data storage unit 51A is a storage area of ​​storage unit 33 for storing the detection data corresponding to tire 11A. Data storage unit 51B is a storage area of ​​storage unit 33 for storing the detection data corresponding to tire 11B. Data storage unit 51C is a storage area of ​​storage unit 33 for storing the detection data corresponding to tire 11C. Data storage unit 51D is a storage area of ​​storage unit 33 for storing the detection data corresponding to tire 11D.

[0054] Upon receiving the detection data sent from the first communication device 2, the control unit 31 determines the destination for storing the received detection data. Specifically, the control unit 31 determines a data storage unit 51 as the destination for storing the detection data based on the detection device identification information contained in the received detection data and the vehicle information stored in the storage unit 33. The control unit 31 then stores the received detection data in the data storage unit 51 determined as the destination.

[0055] Here, the tire pressure management system 100 according to the first embodiment of this disclosure can reduce the workload of the staff of the business office in inspecting the vehicle 1 when the vehicle 1 is returned to the business office.

[0056] Specifically, the control unit 31 includes Figure 2 The acquisition processing unit 61, correction processing unit 62, and first output processing unit 63 are shown. For example, the control unit 31 executes a pressure management program pre-stored in the storage unit 33, thereby functioning as the acquisition processing unit 61, correction processing unit 62, and first output processing unit 63. Furthermore, some or all of the processing units included in the control unit 31 may be constructed using electronic circuitry. Moreover, the pressure management program may be a program that enables multiple processors to function as the various processing units.

[0057] The processing unit 61 acquires the air pressure of the tire 11 installed on the vehicle 1 and the air temperature inside the tire 11.

[0058] Specifically, the acquisition and processing unit 61 acquires the tire pressure and air temperature of the tire 11 at the first moment when the vehicle 1 stops within a predetermined first specific range.

[0059] Here, the first specific range is the range corresponding to the business premises that serve as the return location for vehicle 1.

[0060] For example, the first specific range is the communication range of the first communication device 2 installed at the business premises in accordance with the first wireless communication standard.

[0061] In this case, the acquisition processing section 61 determines whether or not the vehicle 1 is stopped within the first specific range, based on whether or not the communication of the first communication device 2 with the air pressure detecting device 12 is successful. For example, in a case where the communication of the first communication device 2 with the air pressure detecting device 12 is successful, and in a case where the communication continues beyond a predetermined first determination time after that, the acquisition processing section 61 determines that the vehicle 1 is stopped within the first specific range. In addition, the acquisition processing section 61 can determine whether or not the communication of the air pressure detecting device 12 with the first communication device 2 is successful and continues, based on the transmission condition of the detection data from the first communication device 2.

[0062] For example, in a case where the first time elapses, the acquisition processing section 61 acquires the air pressure and the air temperature of the tire 11 for each of the four tires 11. Specifically, the acquisition processing section 61 acquires the air pressure information and the temperature information included in the detection data whose reception date and time information is the latest, from the data holding section 51, for each of the four tires 11. In addition, the acquisition processing section 61 can acquire the air pressure and the air temperature of the tire 11 for any one or more of the four tires 11.

[0063] In addition, a magnetic sensor that can detect the vehicle 1 in a predetermined stop area of the business office can be provided in the business office. In this case, the first specific range can be the stop area. Also, the acquisition processing section 61 can determine whether or not the vehicle 1 is stopped within the first specific range, using the magnetic sensor.

[0064] The correction processing section 62 corrects the air pressure of the tire 11 acquired together with the air temperature of the tire 11, based on the difference between the air temperature of the tire 11 acquired by the acquisition processing section 61 and a predetermined reference temperature.

[0065] For example, the reference temperature is a temperature determined based on the average temperature of one day of the location of the business office. In this case, the reference temperature is updated at a predetermined update period of one month or the like. In addition, the reference temperature can be a temperature that does not change throughout the year, or a temperature determined according to the season.

[0066] For example, the storage section 33 holds, in advance, correspondence relationship information indicating a correspondence relationship between the difference between the air temperature of the tire 11 and the reference temperature, and a correction value for correction of the air pressure of the tire 11. For example, the correspondence relationship information is a mathematical expression or table data.

[0067] In this case, the correction processing portion 62 acquires the correction value corresponding to the difference between the air temperature of the tire 11 acquired by the acquisition processing portion 61 and the reference temperature using the correspondence information. Also, the correction processing portion 62 adds the acquired correction value to the air pressure of the tire 11 acquired by the acquisition processing portion 61, thereby correcting the air pressure.

[0068] For example, the correction processing portion 62 corrects the air pressure each time the air pressure and the air temperature of the tire 11 are acquired by the acquisition processing portion 61. Also, the correction processing portion 62 attaches the corrected air pressure information indicating the corrected air pressure to the detection data including the air pressure before correction saved in the data saving portion 51.

[0069] The first output processing portion 63 outputs determination information for determining whether or not the air pressure adjustment of the tire 11 is required based on the air pressure corrected by the correction processing portion 62.

[0070] Specifically, the first output processing portion 63 outputs the determination information based on the first corrected air pressure acquired at the first time and corrected by the correction processing portion 62.

[0071] For example, the determination information includes first determination information indicating that the air pressure adjustment of the tire 11 is not required and second determination information indicating that the air pressure adjustment of the tire 11 is required.

[0072] In this case, the first output processing portion 63 outputs the first determination information in a case where the first corrected air pressure exceeds a first threshold value determined in advance. Also, the first output processing portion 63 outputs the second determination information in a case where the first corrected air pressure is equal to or less than the first threshold value.

[0073] For example, the first output processing portion 63 outputs the determination information to the four tires 11 respectively in a case where the first time comes.

[0074] For example, the first output processing portion 63 outputs the determination information to the display portion of the terminal device 3. Thereby, in a case where the vehicle 1 is returned to the business office, the employee of the business office can omit the inspection work of the air pressure of the tire 11.

[0075] In addition, the determination information can be information not including the determination result of whether or not the air pressure adjustment of the tire 11 is required by the control portion 31. For example, the determination information can be information indicating only that the first corrected air pressure is notified.

[0076] In addition, the first output processing portion 63 can transmit an e-mail including the determination information to the e-mail address of the user registered in advance to the management server 4.

[0077] Further, in the tire air pressure management system 100 of the first embodiment of the present disclosure, the user can be prompted to adjust the air pressure of the tire 11 before the vehicle 1 is returned to the business office.

[0078] Specifically, the acquisition processing section 61 acquires the air pressure and the air temperature of the tire 11 at a second timing at which the vehicle 1 moves outside a second specific range that is predetermined.

[0079] Here, the second specific range is a range corresponding to the business office that is a rental site of the vehicle 1.

[0080] For example, the second specific range is the same range as the first specific range. That is, the second specific range is a communication range of the wireless communication according to the first wireless communication standard of the first communication device 2 provided at the business office.

[0081] In this case, the acquisition processing section 61 determines whether the vehicle 1 moves outside the second specific range based on whether the communication between the first communication device 2 and the air pressure detection device 12 is successful or not. For example, in a case where the communication between the first communication device 2 and the air pressure detection device 12 is interrupted, and the interrupted state of the communication continues for more than a second determination time that is predetermined, the acquisition processing section 61 determines that the vehicle 1 moves outside the second specific range.

[0082] For example, in a case where the second timing comes, the acquisition processing section 61 acquires the air pressure and the air temperature of the tire 11 for each of the four tires 11. Specifically, the acquisition processing section 61 acquires the air pressure information and the temperature information included in the detection data of the latest reception date and time information from the data holding section 51 for each of the four tires 11.

[0083] Further, in a case where the rental site of the vehicle 1 is the business office that is different from the return site of the vehicle 1, the second specific range becomes a range that is different from the first specific range.

[0084] Further, the control section 31 includes Figure 2 the second output processing section 64 and the first assignment processing section 65 illustrated in the drawing. For example, the control section 31 executes the air pressure management program, thereby functioning as the second output processing section 64 and the first assignment processing section 65.

[0085] In a case where the second corrected air pressure acquired at the second timing and corrected by the correction processing section 62 is less than a first reference value that is predetermined, the second output processing section 64 outputs first notification information including this content.

[0086] For example, the first reference value is the same value as the first threshold value. Further, the first reference value can be a value that is different from the threshold value.

[0087] For example, the first notification information includes the content that the second corrected air pressure of the tire 11 is below the first reference value, information indicating the mounting position of the tire 11, and the content that the air pressure adjustment of the tire 11 is commissioned.

[0088] For example, in the case where the second time comes, the second output processing section 64 determines whether the second corrected air pressure is below the first reference value for each of the four tires 11. Also, in the case where it is determined that the second corrected air pressure is below the first reference value for one or more tires 11, the second output processing section 64 outputs the first notification information. Alternatively, the second output processing section 64 can determine whether the second corrected air pressure is below the first reference value for any one or more of the four tires 11.

[0089] For example, the second output processing section 64 transmits an email including the first notification information to the email address of the user registered in advance in the management server 4. Thereby, the user can be prompted to perform the air pressure adjustment of the tire 11.

[0090] Also, the first notification information can include one or more of the content that the second corrected air pressure of the tire 11 is below the first reference value, information indicating the mounting position of the tire 11, and the content that the air pressure adjustment of the tire 11 is commissioned.

[0091] In the case where a predetermined first giving condition is satisfied, the first giving processing section 65 gives a predetermined first benefit to the user.

[0092] Specifically, the first giving condition is that the first corrected air pressure acquired at the first time coming after the output of the first notification information exceeds the first reference value.

[0093] For example, the first benefit is a first coupon for reduction of the rental fee of the vehicle 1.

[0094] Specifically, in the case where the first time comes after the output of the first notification information, the first giving processing section 65 determines whether the first corrected air pressure exceeds the first reference value for each of the tires 11 determined that the second corrected air pressure is below the first reference value. Also, in the case where it is determined that the first corrected air pressure exceeds the first reference value for all or a part of the tires 11 determined that the second corrected air pressure is below the first reference value, the first giving processing section 65 gives the first benefit to the user.

[0095] For example, the first benefit giving processing section 65 transmits an email containing the first coupon to the email address of the user who is registered in advance in the management server 4. Thereby, the driver of the vehicle 1 can be more strongly prompted to perform the air pressure adjustment of the tire 11.

[0096] In addition, the first benefit can also be a point of a point service provided by the rental car business operator. In this case, the storage section 33 can also have in advance stored point information indicating a point number of the point held by the user. Also, the first benefit giving processing section 65 can give the point to the user by rewriting the point information. Also, the first benefit is not limited to the first coupon or the point, but can be any benefit that gives an economic advantage or a right to the user.

[0097] In addition, in the tire air pressure management system 100 of the first embodiment of the present disclosure, the abnormality of the tire 11 can be detected in a case where the vehicle 1 is rented to the user.

[0098] Specifically, the control section 31 includes Figure 3 the detection processing section 66 and the third output processing section 67 illustrated in FIG. 1. For example, the control section 31 executes the air pressure management program, thereby functioning as the detection processing section 66 and the third output processing section 67.

[0099] The detection processing section 66 detects the abnormality of the tire 11 based on the second corrected air pressure acquired at the second time and the first corrected air pressure acquired at the first time closest to the second time. Here, the abnormality is an abnormality related to the decreasing speed of the air pressure of the tire 11.

[0100] For example, the detection processing section 66 detects the abnormality in a case where the decreasing speed of the air pressure acquired based on the first corrected air pressure and the second corrected air pressure exceeds a second threshold value determined in advance. Here, the second threshold value is a value for determining whether the decreasing speed of the air pressure of the tire 11 is faster than that of a normal tire.

[0101] For example, the detection processing section 66 divides the difference between the first corrected air pressure and the second corrected air pressure by the elapsed time from the first time to the second time, thereby acquiring the decreasing speed. In addition, the first corrected air pressure can be acquired from the data storage section 51.

[0102] For example, in a case where the second time comes, the detection processing section 66 determines the presence or absence of the abnormality for each of the four tires 11. In addition, the detection processing section 66 can determine the presence or absence of the abnormality for any one or more of the four tires 11.

[0103] In a case where the abnormality is detected by the detection processing section 66, the 3rd output processing section 67 outputs 2nd notification information containing the content.

[0104] For example, the 2nd notification information contains degree information indicating the degree of the abnormality based on the difference between the decrease speed and the 2nd threshold value, and a message indicating that the tire needs to be replaced. Also, the 2nd notification information contains information indicating the mounting position of the tire 11 in which the abnormality is detected.

[0105] For example, the degree information is information indicating the degree of the abnormality in 5 stages from "1" (the lightest) to "5" (the heaviest). The larger the difference between the decrease speed and the 2nd threshold value, the higher the value of the degree information.

[0106] For example, the 3rd output processing section 67 outputs size information indicating the size of the tire 11 and kind information indicating the kind of the tire 11 together with the 2nd notification information. Here, the kind information is information of the name of the manufacturing company of the tire 11 and the name of the product, and the like. The size information and the kind information are information contained in the vehicle information which is stored in the storage section 33 in advance.

[0107] For example, the 3rd output processing section 67 transmits an email containing the 2nd notification information, the size information, and the kind information to the email address of the user registered in the management server 4 in advance. Thereby, the user can be prompted to take measures such as suspension of use of the vehicle 1 and replacement of the tire.

[0108] In addition, the 3rd output processing section 67 outputs the 2nd notification information, the size information, and the kind information to the display section of the terminal device 3. Thereby, the staff of the business office can be prompted to take measures such as suspension of rental of the vehicle 1.

[0109] In addition, the 3rd output processing section 67 can output only one of the size information and the kind information together with the 2nd notification information. Also, the 3rd output processing section 67 can output only the 2nd notification information. Also, the 2nd notification information can not contain any one or more of the degree information, the message, and the information indicating the mounting position of the tire 11 in which the abnormality is detected.

[0110] Additionally, the acquisition processing unit 61 can acquire the tire pressure and air temperature of the tire 11 at a predetermined acquisition cycle after the arrival of the first moment. In this case, the detection processing unit 66 can also detect the abnormality based on the first corrected tire pressure acquired at the first moment and the tire pressure acquired after the arrival of the first moment and corrected by the correction processing unit 62. Furthermore, the third output processing unit 67 can also output the second notification information to the display unit of the terminal device 3 if the detection processing unit 66 detects the abnormality.

[0112] The following is for reference Figure 4 The tire pressure management method of this disclosure will be described together with an example of the first tire pressure management process performed by the control unit 31 of the management server 4 in the tire pressure management system 100. Here, steps S11, S12... denote the numbers of the processing procedures (steps) performed by the control unit 31.

[0113] <Step S11>

[0114] First, in step S11, the control unit 31 determines whether the second moment has arrived. Here, the processing in step S11 is performed by the acquisition processing unit 61 of the control unit 31.

[0115] Here, when the control unit 31 determines that the second moment has arrived (S11 "yes" side), the process is transferred to step S12. Furthermore, if the second moment has not arrived (S11 "no" side), the control unit 31 waits for the arrival of the second moment in step S11.

[0116] <Step S12>

[0117] In step S12, the control unit 31 acquires the air pressure and air temperature of each tire 11. Here, the processing in step S12 is performed by the acquisition processing unit 61 of the control unit 31.

[0118] <Step S13>

[0119] In step S13, the control unit 31 corrects the air pressure of each tire 11 obtained in step S12. Here, the processing in step S13 is performed by the correction processing unit 62 of the control unit 31.

[0120] <Step S14>

[0121] In step S14, the control unit 31 determines whether the abnormality is detected in each tire 11. Here, the processing in step S14 is performed by the detection processing unit 66 of the control unit 31.

[0122] Specifically, the control section 31 detects the abnormality of the tire 11 based on the second corrected air pressure acquired in step S13 and the first corrected air pressure acquired at the most recent first timing.

[0123] Here, when the control section 31 determines that the abnormality is detected for one or more tires 11 (YES side of S14), the process is transferred to step S17. Also, if the abnormality is not detected for any of the four tires 11 (NO side of S14), the control section 31 transfers the process to step S15.

[0124] <Step S15>

[0125] In step S15, the control section 31 determines for each tire 11 whether the second corrected air pressure acquired in step S13 is equal to or less than the first reference value.

[0126] Here, when the control section 31 determines that the second corrected air pressure is equal to or less than the first reference value for one or more tires 11 (YES side of S15), the process is transferred to step S16. Also, if the second corrected air pressure is not equal to or less than the first reference value for any of the four tires 11 (NO side of S15), the control section 31 transfers the process to step S18.

[0127] <Step S16>

[0128] In step S16, the control section 31 outputs the first notification information including the content that the second corrected air pressure acquired in step S13 is equal to or less than the first reference value. Here, the process of step S16 is executed by the second output processing section 64 of the control section 31.

[0129] For example, the control section 31 transmits an email including the first notification information to the email address of the user registered in advance in the management server 4.

[0130] <Step S17>

[0131] In step S17, the control section 31 outputs the second notification information including the content that the abnormality is detected in step S14. Here, the process of step S17 is executed by the third output processing section 67 of the control section 31.

[0132] For example, the control section 31 transmits an email including the second notification information, the size information, and the kind information to the email address of the user registered in advance in the management server 4. Also, the control section 31 outputs the second notification information, the size information, and the kind information to the display section of the terminal device 3.

[0133] <Step S18>

[0134] In step S18, the control section 31 executes the 1st determination information output process explained below.

[0135] [1st determination information output process]

[0136] Next, an example of the procedure of the 1st determination information output process executed in step S18 of the 1st air pressure management process will be described with reference to Figure 5

[0137] <Step S21>

[0138] First, in step S21, the control section 31 determines whether the 1st time has come. Here, the process of step S21 is executed by the acquisition processing section 61 of the control section 31.

[0139] Here, the control section 31, when determining that the 1st time has come (YES side of S21), causes the process to shift to step S22. Also, if the 1st time has not come (NO side of S21), the control section 31 waits for the 1st time to come in step S21.

[0140] <Step S22>

[0141] In step S22, the control section 31 acquires the air pressure and the air temperature of each of the tires 11. Here, the process of step S22 is an example of the acquisition step of the present disclosure, and is executed by the acquisition processing section 61 of the control section 31.

[0142] <Step S23>

[0143] In step S23, the control section 31 corrects the air pressure of each of the tires 11 acquired in step S22. Here, the process of step S23 is an example of the correction step of the present disclosure, and is executed by the correction processing section 62 of the control section 31.

[0144] <Step S24>

[0145] In step S24, the control section 31 outputs the determination information to each of the tires 11. Here, the process of step S24 is an example of the output step of the present disclosure, and is executed by the 1st output processing section 63 of the control section 31.

[0146] <Step S25>

[0147] In step S25, the control section 31 determines whether the 1st assignment condition is satisfied.

[0148] ​Here, the control section 31 causes the processing to proceed to step S26 when it is determined that the first giving condition is satisfied (YES side of S25). If the first giving condition is not satisfied (NO side of S25), the control section 31 ends the first determination information output processing.

[0149] <Step S26>

[0150] In step S26, the control section 31 gives the first discount to the user. Here, the processing of step S26 is performed by the first giving processing section 65 of the control section 31.

[0151] Thus, in the tire air pressure management system 100, the air pressure of the tire 11 and the air temperature are acquired, and the air pressure is corrected based on the air temperature acquired together with the air pressure. Further, the determination information based on the corrected air pressure, i.e., the first corrected air pressure, is output to the terminal device 3. Thereby, it is possible to eliminate the need for the employee of the business office to perform the inspection work of the air pressure of the tire 11. Therefore, it is possible to reduce the work burden of the employee on the inspection work of the vehicle 1.

[0152] Further, in the tire air pressure management system 100, the determination information is output based on the air pressure and the air temperature of the tire 11 acquired at the first time when the vehicle 1 is stopped in the first specific range. Thereby, it is possible to output the determination information based on the air pressure at the time immediately before the inspection work of the vehicle 1 is performed. Therefore, it is possible to improve the determination accuracy of whether or not the adjustment of the air pressure of the tire 11 is needed.

[0153] Further, in the tire air pressure management system 100, the determination information includes the first determination information indicating that the adjustment of the air pressure of the tire 11 is not needed and the second determination information indicating that the adjustment of the air pressure of the tire 11 is needed. Further, in the case where the first corrected air pressure exceeds the first threshold value, the first determination information is output, and in the case where the first corrected air pressure is equal to or less than the first threshold value, the second determination information is output. Thereby, compared with the structure in which the determination information simply includes only the corrected air pressure, it is possible to save the effort of the employee of the business office to determine whether or not the adjustment of the air pressure is needed based on the corrected air pressure.

[0154] Further, in the tire air pressure management system 100, the air pressure and the air temperature of the tire 11 are acquired at the second time when the vehicle 1 moves outside the second specific range. Further, in the case where the second corrected air pressure acquired and corrected at the second time is equal to or less than the first reference value, the first notification information including the content is transmitted to the e-mail address of the user. Thereby, it is possible to make the user aware that the air pressure of the tire 11 is equal to or less than the first reference value. Therefore, it is possible to prompt the user to perform the adjustment of the air pressure of the tire 11.

[0155] Further, in the tire air pressure management system 100, in a case where the first corrected air pressure acquired at the first timing coming after the output of the first notification information exceeds the first reference value, the first benefit is given to the user. Thereby, the user can be more strongly prompted to perform the air pressure adjustment of the tire 11.

[0156] Further, in the tire air pressure management system 100, the air pressure and the air temperature of the tire 11 are acquired at the second timing at which the vehicle 1 moves outside the second specific range. Further, the abnormality of the tire 11 is detected on the basis of the second corrected air pressure acquired and corrected at the second timing and the first corrected air pressure acquired at the nearest first timing to the second timing. Further, in a case where the abnormality is detected, the second notification information including the content is output to the email address and the terminal device 3 of the user. Thereby, the user can be prompted to perform a countermeasure such as suspension of use of the vehicle 1 and replacement of the tire, and the staff of the business office can be prompted to perform a countermeasure such as suspension of rental of the vehicle 1.

[0157] Further, in the tire air pressure management system 100, in a case where the decreasing speed of the air pressure of the tire 11 acquired on the basis of the first corrected air pressure and the second corrected air pressure exceeds the second threshold value, the abnormality is detected. Thereby, the abnormality of the tire 11 can be detected with high accuracy.

[0158] Further, in the tire air pressure management system 100, the second notification information includes the degree information indicating the degree of the abnormality based on the difference between the decreasing speed and the second threshold value and a message indicating that the tire needs to be replaced. Thereby, the user or the like can be explicitly informed of the necessity of replacement of the tire and the degree of necessity. Therefore, the user or the like can be more strongly prompted to perform a countermeasure such as replacement of the tire.

[0159] Further, in the tire air pressure management system 100, the size information of the tire 11 and the kind information of the tire 11 are output together with the second notification information. Thereby, when the user or the like prepares a new tire 11 for replacement, the effort of investigating the size and the kind of the tire 11 used so far can be saved.

[0160] Further, in the tire air pressure management system 100, whether or not the vehicle 1 is stopped within the first specific range is determined on the basis of whether or not the communication between the first communication device 2 and the air pressure detection device 12 is successful. Thereby, whether or not the vehicle 1 is stopped within the first specific range can be determined without additionally providing a unit that acquires the position information of the vehicle 1 or a unit that detects that the vehicle 1 is stopped within the first specific range. Therefore, the structure of the tire air pressure management system 100 can be simplified.

[0161] [Second Implementation]

[0162] Next, refer to Figure 6 and Figure 5 The structure of the tire pressure management system 200 according to the second embodiment of this disclosure will be described.

[0163] like Figure 5 As shown, the tire pressure management system 200 includes a vehicle 1, a terminal device 3, a management server 4, and a second communication device 5. In the tire pressure management system 200, the management server 4 is connected to the second communication device 5 and the terminal device 3 via the communication network in a manner that enables communication between them. Furthermore, the structure of the terminal device 3 is the same as that of the tire pressure management system 100.

[0164] Vehicle 1, in addition to having Figure 5 Except for the vehicle communication device 13 shown, it has the same structure as the vehicle 1 with the tire pressure management system 100. Hereinafter, only the structure that is different from that of the vehicle 1 with the tire pressure management system 100 will be described.

[0165] The vehicle communication device 13 receives the detection data sent from the barometric pressure detection device 12. Specifically, the vehicle communication device 13 performs wireless communication with the barometric pressure detection device 12 according to the first wireless communication standard and receives the detection data sent from the barometric pressure detection device 12.

[0166] In the tire pressure management system 200, both the tire pressure detection device 12 and the vehicle communication device 13 are installed in the vehicle 1. Therefore, the tire pressure detection device 12 can always communicate with the vehicle communication device 13. The tire pressure detection device 12 performs the detection process and the transmission process according to the execution cycle.

[0167] Additionally, the vehicle communication device 13 acquires location information indicating the current location of the vehicle 1. For example, the vehicle communication device 13 includes a GPS receiver capable of receiving radio waves transmitted from GPS satellites. The vehicle communication device 13 acquires the location information based on the information contained in the radio waves received by the GPS receiver.

[0168] Additionally, the vehicle-mounted communication device 13 transmits the received detection data to the second communication device 5. For example, the vehicle-mounted communication device 13 communicates with the second communication device 5 (refer to...) which is within communication range of a predetermined second wireless communication standard at a distance from the vehicle-mounted communication device 13. Figure 5Wireless communication according to the second wireless communication standard is performed between the vehicle communication device 13 and the second communication device 5, which is located within a range of several kilometers. For example, the second wireless communication standard is LTE. In this case, the vehicle communication device 13 can perform wireless communication with the second communication device 5, which is located within a range of several kilometers. Alternatively, the second wireless communication standard may be a standard different from LTE.

[0169] Upon receiving the detection data from the barometric pressure detection device 12, the vehicle communication device 13 adds second supplementary data to the received detection data. Furthermore, the vehicle communication device 13 transmits the detection data with the second supplementary data to the second communication device 5. The second supplementary data includes the location information and date and time information indicating the date and time of receipt of the detection data, etc.

[0170] In addition, the vehicle communication device 13 has a display unit for displaying information output from the management server 4.

[0171] The second communication device 5 receives the detection data sent from the vehicle-mounted communication device 13 and sends the received detection data to the management server 4. The second communication device 5 can be installed inside the business office or at any location outside the business office.

[0172] like Figure 6 As shown, the second communication device 5 includes a second antenna 22. The second antenna 22 is used for wireless communication with the vehicle-mounted communication device 13. The second communication device 5 performs wireless communication according to the second wireless communication standard with the vehicle-mounted communication device 13, which is located within the communication range of the second antenna 22 according to the second wireless communication standard.

[0173] Upon receiving the detection data from the vehicle-mounted communication device 13, the second communication device 5 sends the received detection data to the management server 4.

[0174] The difference between management server 4 and processing unit 61 lies in the processing content of the processing unit. Figure 7 Except for the fourth output processing unit 68 shown, it has the same structure as the management server 4 of the tire pressure management system 100. Hereinafter, only the structure that differs from the management server 4 of the tire pressure management system 100 will be described.

[0175] The acquisition and processing unit 61 determines whether the vehicle 1 has stopped within the first specific range and whether the vehicle 1 has moved outside the second specific range based on the location information contained in the detection data sent from the second communication device 5.

[0176] For example, in a tire pressure management system 200, the first specific range and the second specific range are the premises of the business location.

[0177] In addition, the acquisition processing portion 61 acquires the air pressure and the air temperature of the tire 11 at a third timing at which the vehicle 1 is stopped outside the first specific range. Specifically, the acquisition processing portion 61 determines whether the vehicle 1 is stopped outside the first specific range on the basis of the position information included in the detection data transmitted from the second communication device 5. In addition, the acquisition processing portion 61 can acquire the air pressure and the air temperature of the tire 11 at any timing between the second timing and the first timing. For example, the acquisition processing portion 61 can acquire the air pressure and the air temperature of the tire 11 during travel of the vehicle 1. In this case, the correction processing portion 62 corrects the air pressure of the tire 11 on the basis of the air pressure and the air temperature of the tire 11 acquired during travel of the vehicle 1.

[0178] The fourth output processing portion 68 outputs air pressure data including the first corrected air pressure, the second corrected air pressure, and a third corrected air pressure acquired at the third timing and corrected by the correction processing portion 62.

[0179] For example, the air pressure data is data including a graph indicating a change in the air pressure of each of the tires 11 between the second timing and the first timing, the graph being created on the basis of the second corrected air pressure, the third corrected air pressure, and the first corrected air pressure acquired between the second timing and the first timing. In addition, the air pressure data can include a corrected air pressure acquired during travel of the vehicle 1 and corrected by the correction processing portion 62.

[0180] For example, in the case where the first timing has come, the fourth output processing portion 68 generates the air pressure data. Then, the fourth output processing portion 68 outputs the generated air pressure data to the display portion of the in-vehicle communication device 13. Further, the fourth output processing portion 68 can transmit an email including the air pressure data to the email address of the user. Thus, the user or the driver of the vehicle 1 can determine whether his or her driving is good on the basis of the air pressure data.

[0181] In addition, the fourth output processing portion 68 can determine whether the driving of the driver of the vehicle 1 is good on the basis of the air pressure data, and attach the determination result to the air pressure data.

[0182] For example, the fourth output processing section 68 divides the period from the second time to the first time at equal intervals and calculates the reduction speed of the air pressure for each divided period. Also, the fourth output processing section 68 determines whether or not the driving of the driver of the vehicle 1 is good in accordance with the proportion of the number of the calculated speeds exceeding a predetermined reference speed to the number of the calculated speeds. For example, the fourth output processing section 68 evaluates whether or not the driving of the driver of the vehicle 1 is good in ten stages from "10" (best) to "1" (worst). In this case, the lower the proportion, the higher the evaluation value of the fourth output processing section 68 indicating whether or not the driving of the driver of the vehicle 1 is good.

[0183] In addition, in a case where the user logs in to the management server 4 using a terminal device such as a smartphone, the fourth output processing section 68 can also cause the display section of the terminal device to display the air pressure data. In this case, it is sufficient that the storage section 33 previously holds authentication information for the user to log in to the management server 4. Also, in a case where the authentication information is input to the management server 4 via the terminal device of the user, the management server 4 can log in the user to the management server 4. In addition, the authentication information is a user name and a password or the like.

[0184] In addition, the first output processing section 63 of the management server 4 can output the determination information to the display section of the on-vehicle communication device 13. Also, the second output processing section 64 of the management server 4 can output the first notification information to the display section of the on-vehicle communication device 13. Also, the third output processing section 67 of the management server 4 can output the second notification information to the display section of the on-vehicle communication device 13. Also, the first output processing section 63 of the management server 4 can output the determination information based on the third corrected air pressure at the third time.

[0185] [Second Air Pressure Management Process]

[0186] Hereinafter, the process of the second air pressure management process performed by the control section 31 of the management server 4 in the tire air pressure management system 200 will be described with reference to the flowchart of FIG. 8. Figure 7 The process of the second air pressure management process performed by the control section 31 of the management server 4 in the tire air pressure management system 200 will be described with reference to the flowchart of FIG. 8.

[0187] The second air pressure management process is the same as the first air pressure management process shown in FIG. 6 except that the process of step S31 (see FIG. 8) is performed instead of the process of step S18 (see FIG. 6). Hereinafter, only the point of difference in the process content from the first air pressure management process will be described. Figure 3 Figure 3 Figure 8

[0188] <Step S31>

[0189] ​​​In step S31, the control unit 31 performs the second determination information output processing as described below.

[0190] [Processing the output of the second judgment information]

[0191] Next, refer to Figure 8 An example of the process of the second determination information output process performed in step S31 of the second air pressure management process will be described.

[0192] The second determination information output processing, in addition to executing steps S41 to S44 (see...), also performs the steps from S41 to S44 (see...). Figure 4 The processing of ) replaces step S21 (refer to) Figure 4 The processing of this point, and in step S26 (refer to) Figure 8 After processing, proceed to step S45 (refer to...). Figure 4 Apart from this aspect of processing, the content being processed is related to... Figure 9 The first determination information output process shown is the same. Below, only the points where the processing content differs from the first determination information output process will be explained.

[0193] <Step S41>

[0194] In step S41, the control unit 31 determines whether the third moment has arrived. Here, the processing in step S41 is performed by the acquisition processing unit 61 of the control unit 31.

[0195] Here, when the control unit 31 determines that the third moment has arrived (S41 "yes" side), the process proceeds to step S42. And, if the third moment has not arrived (S41 "no" side), the control unit 31 proceeds to step S44.

[0196] <Step S42>

[0197] In step S42, the control unit 31 acquires the air pressure and air temperature of each tire 11. Here, the processing in step S42 is performed by the acquisition processing unit 61 of the control unit 31.

[0198] <Step S43>

[0199] In step S43, the control unit 31 corrects the air pressure of each tire 11 obtained in step S42. Here, the processing in step S43 is performed by the correction processing unit 62 of the control unit 31.

[0200] <Step S44>

[0201] In step S44, the control unit 31 determines whether the first moment has arrived. Here, the processing in step S44 is performed by the acquisition processing unit 61 of the control unit 31.

[0202] Here, when the first timing is determined to have come (YES side of S44), the control section 31 causes the processing to proceed to step S22. If the first timing has not come (NO side of S44), the control section 31 causes the processing to proceed to step S41.

[0203] <Step S45>

[0204] In step S45, the control section 31 outputs the air pressure data to the display section of the in-vehicle communication device 13. Here, the processing of step S45 is performed by the fourth output processing section 68 of the control section 31.

[0205] Thus, in the tire air pressure management system 200, at the third timing at which the vehicle 1 is stopped outside the first specified range, the air pressure and the air temperature of the tire 11 are acquired. Further, the air pressure data including the first corrected air pressure, the second corrected air pressure, and the third corrected air pressure acquired and corrected at the third timing is output to the display section of the in-vehicle communication device 13. Thereby, it is possible to satisfy the demand of the driver of the vehicle 1 who wants to know the progress of the air pressure of the tire 11 during the use of the vehicle 1.

[0206] Further, in the tire air pressure management system 200, the in-vehicle communication device 13 can also have each structure included in the management server 4. In this case, the tire air pressure management system 200 can also not include the terminal device 3, the management server 4, and the second communication device 5.

[0207] [Third Embodiment]

[0208] Next, the structure of the tire air pressure management system 300 according to the third embodiment of the present disclosure will be described with reference to Figure 10 and Figure 9

[0209] As shown in Figure 10 , the tire air pressure management system 300 includes the vehicle 1, the first communication device 2, the terminal device 3, and the management server 4. In the tire air pressure management system 300, the management server 4 is connected to the first communication device 2 and the terminal device 3 in a manner that enables communication with each other through the communication network. Further, the structure of the vehicle 1 is the same as that of the tire air pressure management system 100.

[0210] In the tire air pressure management system 300, the first communication device 2 is not provided at the business office but is provided at a refueling station such as a refueling stand or a service station operated by the rental car business operator. Further, the structure of the first communication device 2 is the same as that of the first communication device 2 of the tire air pressure management system 100 except for the difference in the position of installation.

[0211] ​In addition, in the tire air pressure management system 300, the terminal device 3 is provided at the gas station, like the first communication device 2. In addition, the terminal device 3 has the same configuration as the terminal device 3 of the tire air pressure management system 100, except that the position of installation is different.

[0212] In addition, in the tire air pressure management system 300, the first specific range is a range corresponding to the gas station. Specifically, the first specific range is a communication range of wireless communication according to the first wireless communication standard of the first communication device 2 provided at the gas station.

[0213] The management server 4 has the same configuration as the management server 4 of the tire air pressure management system 100, except that the second output processing section 64, the first assignment processing section 65, the detection processing section 66, and the third output processing section 67 are not included, and the second assignment processing section 69 is included. Figure 5 The management server 4 has the same configuration as the management server 4 of the tire air pressure management system 100, except that the second output processing section 64, the first assignment processing section 65, the detection processing section 66, and the third output processing section 67 are not included, and the second assignment processing section 69 is included.

[0214] The second assignment processing section 69 can assign a predetermined second benefit to the user when the first corrected air pressure is within a predetermined reference range. Here, the reference range is a range of values for determining whether the air pressure of the tire 11 is normal.

[0215] For example, the second benefit is a second coupon for a reduction in the rental fee of the vehicle 1 or the price of gasoline provided by the gas station. In addition, the second benefit can also be a ticket that allows free tire 11 blowout repair at the gas station.

[0216] For example, the second assignment processing section 69 assigns the second benefit to the user when the first corrected air pressure is within the reference range and a predetermined second assignment condition is satisfied.

[0217] For example, the second assignment condition is that the remaining time until the end time of the rental period of the vehicle 1 has elapsed a prescribed time. In this case, the rental period can be registered in advance in the management server 4.

[0218] In addition, in the case where the rental period is long, the second assignment condition can be that the number of visits to the gas station within the past month reaches a prescribed number. In addition, the second assignment condition can include that the stay time of the vehicle 1 at the gas station exceeds a prescribed time. The prescribed time is a time for determining whether the service provided to the vehicle 1 is only refueling service of gasoline.

[0219] In addition, in the case where the second discount is a free ticket for tire repair, the second granting condition can also include a determination that the tire 11 is punctured based on the air pressure acquired thereafter. In this case, the vehicle 1 can also be provided with the on-vehicle communication device 13 (see Figure 11 ), and can transmit the detection data to the management server 4 at any time. Also, in the case where it is determined from the travel route of the vehicle 1 until the tire 11 is punctured that the vehicle 1 is traveling on a shoulder or in contact with a curb, the second discount can also not be granted. The travel route of the vehicle 1 can be acquired from the position information attached to the detection data transmitted from the on-vehicle communication device 13. Also, the determination of whether the vehicle 1 is traveling on a shoulder or in contact with a curb can be performed from the travel route of the vehicle 1 and the map data stored in advance in the storage section 33.

[0220] In addition, in the case where the air pressure after the first correction is outside the reference range, and the air pressure acquired by the acquisition processing section 61 and corrected by the correction processing section 62 before the vehicle 1 moves outside the first specific range is within the reference range, the second granting processing section 69 can grant the second discount to the user.

[0221] For example, in the case where the air pressure acquired by the acquisition processing section 61 and corrected by the correction processing section 62 before the vehicle 1 moves outside the first specific range is within the reference range, and a predetermined third granting condition is satisfied, the second granting processing section 69 grants the second discount to the user.

[0222] For example, the third granting condition is the same condition as the second granting condition. In addition, the third granting condition can also be a different condition from the second granting condition.

[0223] [Third Air Pressure Management Processing]

[0224] Hereinafter, an example of the procedure of the third air pressure management processing performed by the control section 31 of the management server 4 in the tire air pressure management system 300 will be described with reference to ​

[0225] <Step S51>

[0226] First, in step S51, the control section 31 determines whether the first time has come. In other words, the control section 31 determines whether the vehicle 1 is stopped within the communication range of the wireless communication of the first communication device 2 provided at the gas station. Here, the processing of step S51 is performed by the acquisition processing section 61 of the control section 31.

[0227] ​Here, the control section 31 causes the processing to proceed to step S52 when it is determined that the first timing has come (YES side of S51). Also, if the first timing has not come (NO side of S51), the control section 31 waits for the first timing to come in step S51.

[0228] <Step S52>

[0229] In step S52, the control section 31 acquires the air pressure and the air temperature of each of the tires 11. Here, the processing of step S52 is executed by the acquisition processing section 61 of the control section 31.

[0230] <Step S53>

[0231] In step S53, the control section 31 corrects the air pressure of each of the tires 11 acquired in step S52. Here, the processing of step S53 is executed by the correction processing section 62 of the control section 31.

[0232] <Step S54>

[0233] In step S54, the control section 31 outputs the determination information to each of the tires 11. Specifically, the control section 31 outputs the determination information to the display section of the terminal device 3 provided at the gas station. Here, the processing of step S54 is executed by the first output processing section 63 of the control section 31.

[0234] <Step S55>

[0235] In step S55, the control section 31 determines whether the first corrected air pressure acquired in step S53 is within the specific range for all of the four tires 11.

[0236] Here, the control section 31 causes the processing to proceed to step S56 when it is determined that the first corrected air pressure acquired in step S53 is within the specific range for all of the four tires 11 (YES side of S55). Also, if the first corrected air pressure acquired in step S53 is outside the specific range for any one or more of the tires 11 (NO side of S55), the control section 31 causes the processing to proceed to step S57.

[0237] <Step S56>

[0238] In step S56, the control section 31 determines whether the second assignment condition is satisfied.

[0239] Here, the control section 31 causes the processing to proceed to step S59 when it is determined that the second assignment condition is satisfied (YES side of S56). Also, if the second assignment condition is not satisfied (NO side of S56), the control section 31 causes the processing to proceed to step S51.

[0240] <Step S57>

[0241] In step S57, the control section 31 determines whether the pressure acquired and corrected before the vehicle 1 moves outside the first specific range is within the reference range, for the tire 11 for which the first corrected pressure is outside the specific range.

[0242] Here, when the control section 31 determines that the pressure acquired and corrected before the vehicle 1 moves outside the first specific range is within the reference range (YES side of S57) for the tire 11 for which the first corrected pressure is outside the specific range, the process is transferred to step S58. Also, when the control section 31 determines that the vehicle 1 has moved outside the first specific range before the corrected pressure is within the reference range (NO side of S57), the process is transferred to step S51.

[0243] <Step S58>

[0244] In step S58, the control section 31 determines whether the third giving condition is satisfied.

[0245] Here, when the control section 31 determines that the third giving condition is satisfied (YES side of S58), the process is transferred to step S59. Also, if the third giving condition is not satisfied (NO side of S58), the control section 31 transfers the process to step S51.

[0246] <Step S59>

[0247] In step S59, the control section 31 gives the second benefit to the user. Here, the process of step S59 is executed by the second giving processing section 69 of the control section 31.

[0248] Thus, in the tire pressure management system 300, the second benefit can be given to the user in the case where the first corrected pressure is within the reference range, and in the case where the first corrected pressure is outside the reference range and the pressure acquired and corrected before the vehicle 1 moves outside the gas station is within the reference range. Thereby, the user can be prompted to enter the gas station and adjust the pressure.

[0249] Also, the vehicle 1 can be a vehicle other than a taxi vehicle, such as a passenger car or a commercial vehicle. In this case, the first specific range can be a range corresponding to the address or office of the holder of the vehicle 1. Also, the vehicle 1 is not limited to a car, but can be any vehicle in which the tire 11 is installed. For example, the vehicle 1 can include a motorcycle, a three-wheeled passenger car, a truck, a bus, or the like.
