Background Art

In a vehicle, tires which can rotate on wheels are provided and a portion of the tire which is in contact with the road surface is called a tread.


The tread which is the ground surface of the tire is made of a thick rubber layer so as to protect a carcass, a breaker, and the like therein, and in order to ensure a friction coefficient of the road surface and maintain directionality, various shapes of tread marks are processed on the ground surface.


Meanwhile, a groove of the tire tread mark is abraded due to contact with the ground when the vehicle is driven, and as the groove is abraded, a depth of the groove is decreased and thus, the steering and braking performance of the vehicle is deteriorated.

Hereinafter, a tire abrasion confirmation method according to the present invention will be described in detail with reference to FIGS. 1 to 4.



FIG. 4 is a flowchart illustrating a tire abrasion confirmation method according to another embodiment of the present invention.


First, the server 300 receives tire information on the tire mounted on the corresponding vehicle, vehicle information, identification information of the terminal 200, and the like, which are transmitted from the on board diagnostics (OBD) 100 included in the vehicle or the terminal 200 which communicates with the corresponding OBD 100. Herein, the tire information includes a vehicle type, a tire model name, a tire type, a sectional width, a flat ratio, a tire structure, an outer diameter of a rim, a limit load index, a limit speed, and the like. In this case, the tire information may be information on each tire with respect to a plurality of tires mounted on the vehicle or integrated information (alternatively, average information) on the plurality of tires. Further, the vehicle information includes a vehicle type, a vehicle number, a name (or a nickname) of a vehicle owner, tire replacement date information, and the like. Further, the identification information of the terminal 200 includes a MDN, a mobile IP, a mobile MAC, Sim card unique information, a serial number, and the like. In the case, the server 300 may receive the tire information on the tire mounted on the corresponding vehicle, the vehicle information, the identification information of the terminal 200, and the like, which are transmitted from an electronic control unit (ECU) provided in the corresponding vehicle instead of the OBD 100.


Further, the server 300 stores (alternatively, manages) the received tire information, vehicle information, identification information of the terminal 200, and the like.


For example, the server 300 receives first tire information (for example, average information on four tires mounted on the vehicle), first vehicle information, and the like which are transmitted from the OBD 100.


Thereafter, the OBD 100 confirms air pressure information on the tire mounted (alternatively, provided) on the corresponding vehicle (including individual air pressure information on the plurality of tires mounted on the vehicle, average air pressure information on the plurality of tires mounted on the vehicle, or the like) by interlocking with a tire pressure monitoring system (TPMS) provided in the corresponding vehicle.


Further, the OBD 100 confirms trip information including a driving distance of the corresponding vehicle, a distance which may be driven by the remaining oil (alternatively, a drivable distance), fuel efficiency, and the like.


Further, the OBD 100 transmits the confirmed air pressure information on the tire, trip information, vehicle information, and the like to the server 300.


Further, the control unit 300 receives the air pressure information of the tire, the trip information, the vehicle information, and the like which are transmitted from the OBD 100 and stores (alternatively, manages) the received air pressure information of the tire, trip information, vehicle information, and the like.


For example, the OBD 100 confirms first air pressure information (for example, 30 pound per square inch (PSI)) of the tire mounted on the vehicle by interlocking the TPMS, confirms first trip information including a driving distance of the vehicle, and transmits the first air pressure information, the first trip information, the first vehicle information, and the like to the server 300.


Further, the server 300 receives the first air pressure information, the first trip information, the first vehicle information, and the like which are transmitted from the OBD 100 (S420).


Further, when the terminal 200 is positioned in the corresponding vehicle (alternatively, positioned at a place adjacent to the correspond vehicle outside the vehicle) and communicates with the OBD 100, the terminal 200 confirms position information (alternatively, GPS information) of the corresponding terminal 200. In this case, the position information of the terminal 200 may be confirmed based on a GPS technology, an RF signal application indoor and outdoor positioning technology, and the like.


Further, when the terminal 200 is positioned in the corresponding vehicle (alternatively, when the terminal 200 communicates with the OBD 100), the terminal 200 transmits the confirmed position information of the terminal 200, identification information of the terminal 200, and the like to the server 300.


Further, the server 300 receives the position information of the terminal 200, the identification information of the terminal 200, and the like which are transmitted from the terminal 200 and stores (alternatively, manages) the received position information of the terminal 200, identification information of the terminal 200, and the like.


As an example, when the user carrying the terminal 200 sits in the driver's seat in the vehicle, the terminal 200 confirms the GPS information of the terminal 200 in real time and transmits the confirmed GPS information of the terminal 200, identification information of the terminal 200, and the like to the server 300.


Further, the server 300 receives the GPS information of the terminal 200, the identification information of the terminal 200, and the like, which are transmitted from the terminal 200 (S430).


Thereafter, the server 300 analyzes a correlation between the air pressure information of the tire and the driving distance of the vehicle in the trip information based on the received air pressure information of the tire and trip information. In this case, there is an inverse relationship between the air pressure information of the tire and the driving distance of the vehicle.


That is, the server 300 calculates a correction coefficient through analysis of the correlation between the air pressure information of the tire and the driving distance of the vehicle and calculates the corrected driving distance of the vehicle by applying the calculated correction coefficient to the driving distance of the vehicle, because there is a difference in the driving distance of the vehicle according to the air pressure state of the tire. In this case, when the correction is not required by the correlation analysis, the server 300 may use the driving distance of the corresponding vehicle as it is (alternatively, calculate the driving distance of the vehicle corrected by calculating a correction coefficient to ‘1’ and applying the calculated correction coefficient 1 to the corresponding driving distance of the vehicle.


For example, the first driving distance (for example, 1 Km) of the vehicle in the first air pressure information (for example, 30 PSI) and the second driving distance (for example, 1 Km) of the vehicle in the second air pressure information (for example, 35 PSI) are the same as each other, but the air pressure information is different from each other. The server 300 calculates a correction coefficient for correcting the second driving distance of the vehicle in the second air pressure information by predetermined air pressure information (for example, 30 PSI) and calculates the corrected second driving distance (for example, 998 m) of the vehicle by multiplying the calculated correction coefficient by the second driving distance of the vehicle (S440).


Thereafter, the server 300 confirms (alternatively, determines) the abrasion state of the tire based on the above corrected driving distance of the vehicle (alternatively, the driving distance of the vehicle included in the corresponding trip information when the correction is not required according to the above correlation analysis) and the position information of the terminal 200, when the vehicle on which the user carrying the corresponding terminal 200 is boarded is driven in the straight section according to the received position information of the terminal 200.


That is, when the vehicle on which the user carrying the terminal 200 is boarded is driven in the straight section according to the position information of the terminal 200, the server 300 confirms (alternatively, determines) whether the driving distance of the vehicle (alternatively, the corrected driving distance of the vehicle) in the trip information which moves in the corresponding straight section is included in a driving distance section (alternatively, a driving distance range) within a predetermined error range (for example, −5% to +5%) for the distance of the straight section according to the position information of the terminal 200.


As an example, when the vehicle is driven in the first straight section (for example, 1 Km) by the first air pressure information (for example, 30 PSI) which is a predetermined air pressure reference (for example, 30 PSI), the server 300 confirms whether the driving distance (for example, 1 Km) of the vehicle in the first trip information which moves in the corresponding first straight section is included in a first driving distance section (for example, 950 nm to 1,050 m) within a predetermined error range (for example, −5% to +5%) for the distance (for example, 1 Km) of the straight section corresponding to the first straight section driven by the vehicle based on the GPS information of the terminal 200.


As another example, when the vehicle is driven in the second straight section (for example, 1 Km) by the second air pressure information (for example, 35 PSI) which is different from the predetermined air pressure reference (for example, 30 PSI), the server 300 confirms whether the corrected second driving distance (for example, 998 m) of the vehicle which moves in the corresponding second straight section is included in a second driving distance section (for example, 950 nm to 1,050 m) within a predetermined error range (for example, −5% to +5%) for the distance (for example, 1 Km) of the straight section corresponding to the second straight section driven by the vehicle based on the GPS information of the terminal 200. Herein, the corrected second driving distance of the vehicle may be a value corrected by analyzing the correlation between the air pressure information and the driving distance with respect to the second air pressure information which is different from the predetermined air pressure reference.


As yet another example, when the vehicle is driven in a third straight section (for example, 2 Km) by third air pressure information (for example, 30 PSI) which is the predetermined air pressure reference (for example, 30 PSI), the server 300 confirms whether a driving distance (for example, 1.876 Km) of the vehicle in the second trip information which moves in the corresponding second straight section is included in a third driving distance section (for example, 1.900 Km to 2.100 Km) within a predetermined error range (for example, −5% to +5%) for the distance (for example, 2 Km) of the straight section corresponding to the third straight section driven by the vehicle based on the GPS information of the terminal 200 (S450).


As the confirming result (alternatively, the determining result), when the driving distance of the vehicle (alternatively, the corrected driving distance of the vehicle) in the trip information which moves in the corresponding straight section is included in the driving distance section (alternatively, the driving distance range) within the predetermined error range (for example, −5% to +5%) for the distance of the straight section according to the position information of the terminal 200, the server 300 determines that the abrasion degree of the tire (alternatively, the abrasion state of the tire) is in a good state.


Further, the server 300 transmits information indicating that the abrasion degree of the tire is in the good state to the terminal 200 or the OBD 100.


Further, the terminal 200 or the OBD 100 displays the information indicating that the abrasion degree of the tire is in the good state, which is transmitted from the server 300.
