The tire placement confirmation step ( S20 ) may include a step of confirming that the electronic device module is prepared and placed on the tire. For example, a step of confirming information on whether or not an electronic device module is disposed in the tire may be included.

Electronic device modules, for example, the electronic device modules RD shown in FIGS. 2 to 4 may be disposed in various positions of the tire.

Such a tire may be formed to include at least a tread area, and for example, the tread area of the tire may include an area in contact with the road surface during driving of the vehicle.

The vehicle on which the tire is mounted may be of various types, for example, a vehicle, an aircraft, or other various means to which the tire may be applied.

In a state where the electronic device module is disposed on the tire, when driving of the vehicle equipped with the tire starts, driving information may be checked.

As an optional embodiment, when such driving progresses and the traveling amount is accumulated over time, it may include checking travel amount information over time and accumulated travel amount information over time, and managing these information.

The detection and control step ( S40 ) may include detecting tire-related information of a tire that has started a driving process together through at least driving of the means of transportation through an electronic device module disposed on a tire mounted on the means of transportation.

As an optional embodiment, tire-related information that changes according to driving may be sensed due to driving of the tire.

In the time information control step (S41'), time information for the sensing time point may be controlled. For example, information on when the tire on which the electronic device module is disposed is mounted on the means of transportation and information about when the tire on which the electronic element module is placed is mounted on the means of transportation and then driving starts may be checked. In addition, when the driving continues after starting the driving, information on the timing of the continuous driving may be continuously or intermittently checked.

Through this, one or more information can be managed as a set. For example, tire-specific information that does not change according to driving and vertical load information that can change according to driving can be grouped and managed as a set to provide convenience in information management and user convenience of information management. It is possible to improve the convenience of information use by providing it to

In the comparison information control step ( S50 ), the information sensed in the detection control step, for example, the vertical load information of the tire, may be compared with reference information, and judgment result information may be generated.

As an example, the vertical load of the tire according to driving time may be detected through the information detected in the detection and control step, and as a specific example, it may be confirmed that the vertical load value increases according to tire wear.

In addition, when the increased vertical load value exceeds the standard information, information for notifying the need for follow-up management of the tire, such as "state exceeding the standard", may be generated as the determination result information.

For example, as the tire wears out through continued driving, the vertical load received by the tire may increase, and the increased vertical load value may be sensed through the electronic device module in the detection and control step. In addition, if the increase in the vertical load value is greater than the set condition compared to the reference information, for example, if it is increased to have a value too large compared to the vertical load value received by the new tire, this is for safe driving due to severe tire wear. It can be judged that follow-up treatment is necessary.

Referring to FIG. 6, the comparison information control step (S50') may include a reference information control step (S51'), a setting management control step (S52'), or an information generation control step (S53').

In the reference information control step (S51'), the reference information may be controlled, and the reference information may be stored as a unique information value of the tire on which the electronic element module is disposed. As an optional embodiment, the reference information may include a vertical load value detected when the tire on which the electronic device module is disposed is mounted on a means of transportation, for example, mounted on a vehicle. Through this, it is possible to improve the precision of the comparison judgment result.

In the setting management control step (S52'), when comparing the vertical load value detected through the detection control step and reference information, it is possible to determine whether the difference in information meets the setting condition. These setting conditions may be stored in advance, and as another example, they may be changed at least later.

In the information generation control step (S53'), the vertical load value detected through the detection control step is compared with reference information, and when the difference between the information exceeds the set condition, comparison result information corresponding thereto may be generated. This information can be notified to users and the like, and can be notified in the form of text or images for convenience in recognizing information.

For example, information on tire wear exceeding or tire replacement may be generated.

Referring to FIG. 7 , the setting management control step (S52") may include a limit information controller (S521") and a setting condition change controller (S522").

As an optional embodiment, vertical load value corresponding information is generated to correspond to the tire wear limit information, and this information can be compared with the vertical load value detected in the detection and control step.

The setting condition change controller S522" may change the setting condition. For example, the initial setting condition may be a value set in response to wear limit information designed for safe driving of the corresponding tire.

The electronic device module may collect a plurality of pieces of information, collect a vertical load value, and other various driving performance information while being disposed on the tire and moving along with the driving of the means of transportation. By collecting various driving performance information according to continuous driving of the tire, driving performance according to tire wear, for example, noise, vibration, etc., can be identified, and accordingly, wear limit information can be changed in real time. Through this, even in the case of driving a vehicle equipped with the same type of tire, various driving characteristic information is identified according to the type of vehicle, driver's driving method, and driving environment, and different wear limit information is generated accordingly and set as a result. Conditions may vary.

FIG. 8 is a diagram illustrating an alternative embodiment of the information generation control step of FIG. 6;

Referring to FIG. 8 , the information generation control step (S53") may include an information control step (S531") and a signal control step (S532").

In the information control step (S531"), various information can be generated, for example, the vertical load value of the tire at a point in time and comparison information with the set condition through this, as a specific example, the change in the vertical load value compared to the new tire or Corresponding wear information may be generated As an optional embodiment, such information may be generated in real time and provided to the user at a desired time.

In the signal control step (S532"), the generated information can be converted into a signal and prepared to be notified to the user. For example, the generated information is converted into a signal and recognized by an external reader through the antenna unit of the electronic device module. It can be sent to any capable device.

At this time, it may be converted into a signal in an electronic element of the electronic element module, for example, an IC chip, and may be processed and converted to meet necessary information.

FIG. 9 is a diagram showing another optional embodiment of the comparison information control step of FIG. 1; FIG. 10 is a graph for explaining FIG. 9 .

The comparison information control step of FIG. 9 may be used in conjunction with the above-described comparison information control step and its optional embodiments, and may be partially used together with each other if necessary.

Referring to FIG. 9 , the comparison information control step (S50") may include a graph information generation control step (S511"), a peak comparison control step (S512"), and a frequency setting control step (S513"). 9, but as an optional embodiment, the comparison information control step (S50") includes one or more of a graph generation control step (S511"), a peak comparison control step (S512"), and a frequency setting control step (S513"). You may.

The graph information generation control step (S511") may include generating a graph for the vertical load value detected through the detection control step, and as an optional embodiment, graph information simultaneously showing lift information may be generated. Such graph information may be a graph in the form of an actual image or may be a form of digital information corresponding to a plurality of coordinate values.

10 shows a graph by way of example. This may include implementing an image in the form of a graph of FIG. 10, and as another example, it may include corresponding to coordinate information for implementing such a graph image.

10 shows two lines indicating two values. For example, a thick line curve (A) and a lighter line curve (B) are shown.

The Y-axis of the graph of FIG. 10 indicates the vertical load value (SF). The X-axis of FIG. 10 indicates a frequency value (FZ), and this frequency (FZ) is proportional to the speed and may indicate the size of the frequency information of the motion of the tire according to the motion of the vehicle on which the tire is mounted.

Curve (A) represents reference information, and may indicate, for example, a vertical load value measured after mounting a new tire on a means of transportation. As a specific example, a unique information value of a new tire may be used as it is. In addition, as an optional embodiment, a vertical load value may be measured at an initial stage (eg, within 10 km) immediately after driving after mounting a new tire on a means of transportation, for example, a vehicle.

Curve (B) may represent the vertical load value sensed in the sensing control step. As an example, curve (B) may be for a tire that reaches a time when a tire replacement or tire management is required (eg, 10,000 km or more) due to accumulated travel amount.

Referring to curve (A) and curve (B), it can be seen that curve (B) is above curve (A) as a whole except for some frequency regions, which indicates that the state of curve (B) is the state of curve (A). It can indicate that the vertical load value has increased.

When the tire rubs against the road surface while driving, the surface of the tire, for example, the surface of the tread area is worn, and as the tread area in contact with the road surface decreases due to wear, the vertical load received during driving increases, so the initial state curve (A) It can be inferred that the vertical load value of the curve (B), which is the state after more continuous driving, is large and the degree of wear is increased accordingly.

In the peak comparison and control step (S512"), the peak information of the two curves identified through the graph information may be compared. For example, the peak information of the curve for the reference information and the information detected in the detection control step may be compared. can be compared

As a specific example, peak information of curve (A) and peak information of curve (B) may be compared.

As an optional embodiment, as shown in FIG. 10 , the peak information (Pa) of the curve (A) and the peak information (Pb) of the curve (B) can be compared, and information of the difference value (DP) can be checked. If the difference value (DP) is analyzed and exceeds the set condition, it can be determined that the wear degree has reached the limit value, and various information corresponding to this, for example, replacement required information, can be generated and notified.

The frequency setting control step (S513") may set the frequency range for determining the peak. For example, the frequency value corresponding to the peak information (Pa) of the curve (A) corresponds to the peak information (Pb) of the curve (B). It is possible to grasp the information of the difference value (DX) of the frequency value to be determined, and to determine whether the difference value (DX) between these frequency values is within the frequency setting range, and only when it is within the setting range, the peak information (Pa) and the peak information (Pb) ), it is confirmed that the information of the difference value (DP) is valid, and the subsequent process can be performed.

Otherwise, if the difference value (DX) of the frequency values exceeds the frequency setting range, it is determined that the information is highly inaccurate, and graph information after a new detection and control step is performed may be used.

This embodiment uses the arrangement of electronic device modules on the tire, and through this, various tire information can be checked. At this time, the electronic device module proceeds with the vertical load detection and can check this information over time to recognize the change in the vertical load value, and use it as reference information, for example, the state of no or little wear at the initial point of tire mounting. It is compared with the vertical load value, and as a result of this comparison, the information of the difference value is compared with the set condition, and when the set condition is exceeded, it is identified as the wear limit point and safety information such as tire replacement can be generated. In addition, as various safety information, if the corresponding tire is a tire corresponding to the drive shaft, guide information about replacing the tire with a non-drive shaft tire may be generated.

As an optional embodiment, it can be confirmed that the electronic device module is disposed on each of a tire corresponding to a driving shaft and a tire not corresponding to a driving shaft of a moving means such as a vehicle. Through this, in the case of a front- or rear-wheel drive vehicle, it is possible to easily analyze the wear difference between the front tire and the rear tire.

The driving confirmation step (T40) may be the same as or modified within a similar range to that described in the foregoing embodiment.

Such information may include, for example, whether a set condition for each of a plurality of tires is exceeded or whether a wear limit is reached. In addition, as an optional embodiment, after matching the tire exceeding the setting condition and the tire not exceeding the setting condition, replacement guidance information for guiding replacement of the matched tire may be generated, and this information may be notified.

Through this, it is possible to facilitate wear management by facilitating overall vertical load sensing of tires mounted on a means of transportation, for example, a vehicle.
