[0002] Retread tires are sometimes used on large vehicles such as trucks. A "retread tire" is a tire that has been re-applied with a new tread, leaving only the base tire (the casing) so that it can be reused when it wears out. The casing wears out as the vehicle travels, and is damaged when it is consumed beyond its durability. There is a need to accurately predict the remaining durability of the casing, which indicates when it is time to replace it.

[0003] The tire condition determination system disclosed in Patent Document 1 includes an acquisition unit that acquires tire-related information that may affect the deterioration of a base portion corresponding to a casing tire, and a condition determination unit that determines the condition of the base portion based on the tire-related information. The condition data, which is the tire-related information, is acquired from various sensors provided on the vehicle. The condition determination unit calculates an evaluation value indicating the condition of the base portion based on the condition data, and determines that the base portion is applicable as a casing tire if the evaluation value is equal to or greater than a predetermined threshold value.

"MAN" is an abbreviation for metropolitan area network. Network 30 may include at least one wireless network, at least one optical network, or any combination thereof. A wireless network may be, for example, an ad-hoc network, a cellular network, a wireless LAN, a satellite communication network, or a terrestrial microwave network. "LAN" is an abbreviation for local area network.

[0029] The outline of this embodiment will be described.

[0030] The terminal device 20 transmits to the data processing device 10 running data indicating the manually recorded running time and running distance of the vehicle F. The data processing device 10 acquires the running data from the terminal device 20. The data processing device 10 calculates the deterioration amount of the base tire 41 based on the acquired running data. The "deterioration amount" is a numerical value indicating how much of the remaining durability of the base tire 41 has been consumed by running, that is, the durability consumption amount.

Desirably, the terminal device 20 further transmits load data indicating the weight of the luggage corresponding to the traveling data to the data processing device 10. The data processing device 10 acquires the load data from the terminal device 20. The data processing device 10 calculates the deterioration amount of the base tire 41 based on the traveling data and the acquired load data.

[0033] Preferably, the terminal device 20 further transmits temperature data indicating the temperature corresponding to the traveling data to the data processing device 10. The data processing device 10 acquires the load data from the terminal device 20. The data processing device 10 calculates the deterioration amount of the base tire 41 based on the traveling data and the acquired temperature data.

[0034] In this embodiment, the driving data is data that is manually recorded in the terminal device 20 for each unit period. For example, the driver of the vehicle F handwrites the necessary items in the daily driving report for that day after completing the day's work. An example of the daily driving report is shown in FIG. 3. In this example, the daily driving report has columns for entering one or more destinations, departure times and arrival times corresponding to the destinations, and the driving distance for that day. The daily driving report may have columns for entering the weight of the baggage delivered to the destination, or the temperature at the destination. After the driver enters the necessary items in the daily driving report, an employee other than the driver manually inputs the contents of the daily driving report into the terminal device 20 as driving data. The manual input is not limited to manual input using a keyboard, mouse, or touch screen, and may also be OCR reading. "OCR" is an abbreviation for optical character recognition. The driver of the vehicle F may electronically enter the necessary items in the daily driving report for that day using an application installed in the terminal device 20 after completing the day's work. That is, the driver of the vehicle F may manually directly input the contents of the daily driving report into the terminal device 20 as driving data. Among the contents of the daily driving report, the departure time and arrival time corresponding to the destination correspond to the driving time indicated in the driving data, and the driving distance in one day corresponds to the driving distance indicated in the driving data. When the weight of the luggage delivered to the destination is entered in the daily driving report, part of the contents of the daily driving report is input to the terminal device 20 as load data. That is, among the contents of the daily driving report, the weight of the luggage delivered to the destination corresponds to the load indicated in the load data. When the temperature at the destination is entered in the daily driving report, part of the contents of the daily driving report is input to the terminal device 20 as temperature data. That is, among the contents of the daily driving report, the temperature at the destination corresponds to the temperature indicated in the temperature data.

[0035] The "unit period" is not limited to one day, but may be multiple days such as one week or one month. That is, in the example of Fig. 3, the contents of the daily driving report are input to the terminal device 20 on a daily basis, but in other examples, the contents of the daily driving report may be input to the terminal device 20 collectively for multiple days, such as on a weekly or monthly basis. Also, in the example of Fig. 3, the driving time and the driving distance are recorded in a daily report format, but in other examples, the driving time and the driving distance may be recorded in a weekly or monthly report format. The same applies to the case where weight or temperature is recorded.

[0046] The operation of the data processing device 10 according to the present embodiment will be described with reference to Fig. 5. The operation described below corresponds to the data processing method according to the present embodiment. That is, the data processing method according to the present embodiment includes steps S1 to S7 shown in Fig. 5.

[0047] In S1, the control unit 11 acquires the travel data. The travel data is data indicating the manually recorded travel time and travel distance of the vehicle F equipped with the tire 40 including the base tire 41 and the tread 42 attached to the base tire 41 in an exchangeable manner. The travel data may include data indicating the travel time of the vehicle F by the manually recorded departure time and arrival time of the vehicle F, instead of directly indicating the travel time of the vehicle F. For example, each destination entered in the daily driving report on October 10th shown in FIG. 3, the departure time and arrival time corresponding to each destination, and the travel distance for one day are input to the terminal device 20 as the travel data. In such an example, the travel time is 4 hours and 30 minutes, which is a total of 1 hour from the departure time 8:30 to the arrival time 9:30 with the destination CCC Co., Ltd., 2 hours and 30 minutes from the departure time 10:30 to the arrival time 13:00 with the destination DDD Co., Ltd., and 1 hour from the departure time 13:00 to the arrival time 14:00 with the destination head office. The mileage is 90 km, which is entered in the daily mileage column of the daily driving report. The terminal device 20 transmits the entered mileage data to the data processing device 10. The control unit 11 acquires the mileage data from the terminal device 20 via the communication unit 13. In another example, the daily driving report may be transmitted to the service provider by any communication means such as e-mail or facsimile. Then, each destination entered in the daily driving report, the departure time and arrival time corresponding to each destination, and the mileage for one day may be input as mileage data to the terminal device of the service provider, and the control unit 11 may acquire the mileage data from the terminal device of the service provider via the communication unit 13.

[0048] In S2, the control unit 11 acquires load data corresponding to the travel data acquired in S1. The load data is data indicating the weight of the luggage delivered by the vehicle F. Since the daily driving report for October 10 shown in FIG. 3 does not have a column for entering the weight of the luggage delivered to each destination, for example, in the remarks column or outside the column, it is assumed that the total weight of the luggage at the time of departure of the vehicle F is 1 t, the weight of the luggage unloaded at CCC Co., Ltd. is 600 kg, the weight of the luggage unloaded at DDD Co., Ltd. is 300 kg, and the weight of the luggage unloaded at the head office is 100 kg. Then, it is assumed that the weight of the luggage delivered to each destination entered in this daily driving report is input to the terminal device 20 as load data. In such an example, the weight is 500 kg, which is the average of the total of 1 t delivered by the vehicle F from the time of departure to CCC Co., Ltd., the weight of the luggage delivered from CCC Co., Ltd. to DDD Co., Ltd., 400 kg, and the weight of the luggage delivered from DDD Co., Ltd. to the head office. The terminal device 20 transmits the input load data to the data processing device 10. The control unit 11 acquires the load data from the terminal device 20 via the communication unit 13. The daily driving report may be provided with a column for entering the weight of the luggage delivered to each destination. Alternatively, the driver or an employee other than the driver may manually record the weight of the luggage delivered to each destination separately from the daily driving report. Then, the weight of the luggage delivered to each destination recorded separately from the daily driving report may be input to the terminal device 20 as load data. In another example, the vehicle F may step on a weighing scale before departure, and the measurement value of the weighing scale may be automatically transmitted to the terminal device 20. In such an example, the weight is a value obtained by subtracting the weight of the vehicle F itself from the measurement value of the weighing scale. The terminal device 20 transmits the value obtained by subtracting the weight of the vehicle F itself from the transmitted measurement value of the weighing scale to the data processing device 10 as load data. In yet another example, the daily driving report may be transmitted to the service provider by any communication means such as email or facsimile. Then, the weight of the luggage delivered to each destination, which is entered in the daily driving report, is input as load data into the terminal device of the service provider, and the control unit 11 may acquire the load data from the terminal device of the service provider via the communication unit 13.

[0049] In S3, the control unit 11 acquires temperature data corresponding to the travel data acquired in S1. The temperature data is data indicating temperature. Since the daily driving report for October 10 shown in FIG. 3 does not have a column for entering the temperature, for example, the maximum temperature of the area including the destination points CCC Co., Ltd., DDD Co., Ltd., and the head office is entered as 22°C in the margin. Then, the temperature entered in this daily driving report is input to the terminal device 20 as temperature data. In such an example, the temperature is 22°C. The terminal device 20 transmits the input temperature data to the data processing device 10. The control unit 11 acquires the temperature data from the terminal device 20 via the communication unit 13. The daily driving report may have a column for entering the temperature. Alternatively, the driver or an employee other than the driver may manually record the temperature separately from the daily driving report. Then, the temperature recorded separately from the daily driving report may be input to the terminal device 20 as temperature data. In another example, the control unit 11 may acquire data indicating the temperature of a region including the destination indicated in the travel data acquired in S1 from an external system such as a server of the Japan Meteorological Agency via the communication unit 13 as the temperature data, instead of acquiring the temperature data from the terminal device 20. That is, the travel data may further include data indicating the destination point of the vehicle F, and the control unit 11 may acquire data indicating the temperature of the destination point indicated in the travel data as the temperature data. In yet another example, the daily driving report may be transmitted to the service provider by any communication means such as e-mail or facsimile. Then, the temperature entered in the daily driving report may be input as temperature data into the terminal device of the service provider, and the control unit 11 may acquire the temperature data from the terminal device of the service provider via the communication unit 13.

[0050] In S4, the control unit 11 calculates the deterioration amount of the base tire 41 based on the travel data acquired in S1, the load data acquired in S2, and the temperature data acquired in S3. Specifically, the control unit 11 calculates the travel speed of the vehicle F from the travel time and travel distance indicated in the travel data. The control unit 11 then calculates the deterioration amount of the base tire 41 by applying a combination of the travel distance indicated in the travel data, the calculated travel speed, the weight indicated in the load data, and the temperature indicated in the temperature data to a map 14 stored in the storage unit 12, which defines in advance the deterioration amount corresponding to a combination of the travel distance, the travel speed, the weight, and the temperature, to calculate the deterioration amount of the base tire 41. In the example of FIG. 3, the control unit 11 calculates the travel speed of 20 km / hour from the travel time of 4:30 and the travel distance of 90 km indicated in the travel data acquired in S1. The control unit 11 calculates the deterioration amount α of the base tire by applying a combination of the calculated travel speed, the weight of 500 kg indicated in the load data acquired in S2, and the temperature of 22° C. indicated in the temperature data acquired in S3.

[0051] In S5, the control unit 11 updates the accumulated deterioration data stored in the storage by using the value of the deterioration amount of the base tire 41 calculated in S4. The accumulated deterioration data is data indicating the accumulated deterioration amount of the base tire 41. The storage is, for example, the storage unit 12. Specifically, the control unit 11 updates the accumulated deterioration data by adding the calculated value of the deterioration amount to the value of the accumulated deterioration amount of the base tire 41 stored in the storage. In the example of FIG. 3, the control unit 11 updates the accumulated deterioration data by adding the deterioration amount α calculated in S4 to the accumulated deterioration amount β up to October 9. The accumulated deterioration data may be data indicating the accumulated deterioration amount by a remaining durability amount, which is a value obtained by subtracting the accumulated deterioration amount from the initial durability amount of the base tire 41, instead of directly indicating the accumulated deterioration amount of the base tire 41. Then, the control unit 11 may update the accumulated deterioration data by subtracting the calculated value of the deterioration amount, i.e., the value of the durability consumption amount, from the value of the remaining durability amount of the base tire 41 stored in the storage.

[0052] In S6, the control unit 11 judges whether or not the accumulated deterioration amount indicated in the accumulated deterioration data exceeds a threshold value. If the accumulated deterioration amount exceeds the threshold value (S6-Yes), the process proceeds to S7. If the accumulated deterioration amount does not exceed the threshold value (S6-No), the process ends. In the example of FIG. 3, the control unit 11 judges whether or not the accumulated deterioration amount α+β indicated in the accumulated deterioration data exceeds a threshold value γ. After step S6, step S1 may be executed again. Specifically, the control unit 11 may update the accumulated deterioration data every time it acquires driving data from the terminal device 20 via the communication unit 13.

[0053] In S7, the control unit 11 outputs a notification. For example, the control unit 11 transmits, as a notification, a notification that the accumulated deterioration amount indicated in the accumulated deterioration data has exceeded a threshold to the terminal device 20 via the communication unit 13. Upon receiving the notification, the terminal device 20 displays the received notification on a display or outputs it as sound from a speaker. The display is, for example, an LCD or an organic EL display. "LCD" is an abbreviation for liquid crystal display. "EL" is an abbreviation for electro luminescent.

[0054] According to this embodiment, even if the vehicle F is not equipped with equipment capable of automatically recording a driving record, such as a digital tachograph, it is possible to predict the remaining durability of the base tire 41.

[0055] The present disclosure is not limited to the above-mentioned embodiment. For example, two or more blocks shown in the block diagram may be integrated, or one block may be divided.
