The communication signal is a signal transmitted from the vehicle communication network NT to the vehicle, such as the pressure of each wheel of the vehicle measured by the pressure sensor unit 20, And transmit the processed control signals in the tire monitoring system 170 to the various electronic devices 100.

Specifically, although not shown, the communication unit 10 includes an external communication unit and an internal communication unit.

The external communication unit (not shown) can access the server 3 including the database of the tire supplier through communication with the satellite 2, as shown in FIG. In order to improve the accuracy of the tire wear measurement, it is necessary to determine the tire wear rate from the server 3 including the database of the supplier of the tire installed in the vehicle 1, since the tire pressure information and the wear- Abrasion data can be received.

An internal communication unit (not shown) receives information from various electronic devices 100 of the vehicle.

For example, it is possible to check whether the gear position of the vehicle is in the P state or the N state to check whether the vehicle is in the stop state, transmit the processed control signal in the tire monitoring system 170 according to the present invention, It is possible to transmit the control signal so as to display the warning information through the display unit included in the display unit.

Next, the wear rate measuring section 35 can measure the wear rate of the tire. 3 is a schematic view showing a tire according to the present invention and a sectional view including a tread wear indicator provided on a surface of a tire for measuring wear of the tire.

As shown in Fig. 3, the tire may have a tread wear indicator b located on the tread c of the tire and on the top surface of the tire d and on the top of the tread wear indicator b The distance between the surface of the tire and the treadmill indicator b is calculated based on the distance between the surface of the tire a and the treadmill indicator b from the sensor a including the sensor a, It is possible to calculate the wear rate information in the state.

Next, the pressure sensor unit 20 measures the pressure of each tire of the vehicle 1. [ 5 is a schematic view including a pressure sensor included in each wheel of a vehicle equipped with the tire monitoring system according to the present invention.

5, the pressure sensor unit 20 includes four pressure sensors 20A, 20B, 20C, and 20D that detect air pressure of the tire and wirelessly transmit the pressure to the wheels FR, FL, RR, And a TPMS sensor module.

That is, the four pressure sensors 20A, 20B, 20C and 20D are mounted in the vicinity of the TPMS sensor module (not shown) to provide a variable detection value in accordance with the rotational direction (acceleration direction) of the tire.

The travel distance estimating unit 30 measures the travelable distance of the tire and transmits the accumulated travel distance to the electronic control unit 40. [ In addition, the travelable distance can be measured by adding the wear rate information obtained by the wear rate measuring unit 35. [

 That is, the travel distance can be secured by measuring the number of rotations of the tire and the like through the travel distance measuring sensors 30A, 30B, 30C and 30D provided in the tire.

The display unit 70 can inform the driver through the tire status information (Status of Tire X0: X0A, X0B, X0C, and X0D) when the wear degree of each tire is close to the set threshold value or if abnormal (irregular) .

Next, the electronic control unit 40 collectively controls the tire monitoring system 170 according to the present invention.

Specifically, the electronic control unit 40 includes a main processor 50 for calculating the wear degree of the tire, a control signal for calculating the control signal, and a memory 60 for storing various data.

In addition, the main processor 50 can receive abrasion data on the tire held by the tire supplier from the external communication unit in the communication unit 10.

Therefore, the main processor 50 can calculate the wear rate information of the tire currently installed on the vehicle 1 based on the wear rate data corresponding to the tire installed in the vehicle 1, based on the received wear rate data information.

For example, FIG. 6 is a graph showing the degree of wear according to the mileage of the present invention.

The thick solid line is a graph showing the wear rate [%] according to the running distance of the vehicle tire. The abrasion data according to mileage may vary from tire to tire, and wear due to tire air pressure may also vary.

The tire monitoring system 170 according to the present invention can calculate the wear degree according to the tire pressure and the travel distance including the internal data in the main processor 50. However, The tire wear rate and the replacement cycle can be calculated from the data of the tire wear rate and the replacement cycle.

That is, as the wearer information provided by the tire supplier is received, it is possible to accurately calculate the wear value depending on the tire type, and to predict the replacement timing or cycle.

For example, as shown in FIG. 6, the bold solid line indicating the wear rate [%] according to the running distance of the vehicle tire may vary depending on the wear rate information provided by the tire supplier.

The graph indicated by the dotted line is a graph showing a record measured through the tire of the vehicle 1 equipped with the tire monitoring system 170 according to the present invention.

At this time, when the preset threshold value A is reached, the main processor 50 judges that the tire is worn, warns the driver, and can guide the tire changing time in advance.

In addition, since the main processor 50 receives the stop state of the tires and warns when the vehicle 1 is running, the driver can not immediately change the tires. Therefore, Only when the tire is worn, it may warn you to exchange.

Specifically, the tire monitoring system 170 can generate a control signal through the display unit 70 so as to display the air pressure, the wear rate [%] of each tire, the travel distance remaining until a replacement period, and a warning sign .

Next, the memory 60 stores programs and data of the tire monitoring system 170. [

The nonvolatile memory may semi-permanently store a control program and control data for controlling the operation of the navigation system 170. The volatile memory temporarily retrieves and temporarily stores control programs and control data from the nonvolatile memory, 10, and various control signals output from the main processor.

The configuration of the tire monitoring system 170 according to the present invention has been described above.

Hereinafter, FIG. 7 is a flowchart of a method of controlling the tire monitoring system 170 according to the present invention.

First, the tire monitoring system 170 according to the present invention measures the distance traveled on the basis of the signal information in the wear rate measuring sensor for each pressure (air pressure) of each tire (S10). Specifically, the pressure sensor unit 20 is installed in each tire, measures the air pressure of the tire, measures wear of the tire through a separate sensor provided outside the tire, and the travel distance estimating unit 30 also measures the rotation And the like, and transmits to the electronic control unit 40 a value obtained by estimating the travelable distance of each tire.

Accordingly, the electronic control unit 40 can predict the degree of wear of the tire based on the obtained signal information of the tire wear sensor for each pressure (air pressure) of the tire, and calculates the travelable distance of the tire S20) and stores the calculated wear rate data in the memory 60 in the electronic control unit 40 (S30).

At this time, if the wireless communication of the vehicle is established (YES in S40), the tire monitoring system 170 receives the tire wear information from the tire supplier (S50). 3, the communication unit 10 of the tire monitoring system 170 includes an external communication unit (not shown). The external communication unit (not shown) communicates with the satellite 2 via a tire supply It is possible to access the server 3 including the database of the company.

In order to improve the accuracy of the tire wear measurement, it is necessary to determine the tire wear rate from the server 3 including the database of the supplier of the tire installed in the vehicle 1, since the tire pressure information and the wear- Abrasion data can be received.

Accordingly, the electronic control unit 40 analyzes the wear degree of the tire based on the received tire wear rate information (S60), increases the accuracy of the tire wear rate measurement, and determines whether the remaining travelable distance or the replacement time point Can be reduced. (S70).

Next, the tire monitoring system 170 determines whether the vehicle is running (S80). Specifically, when the electronic control unit 40 receives the stop state of the tire or not, the driver can not immediately change the tire even when the vehicle 1 is running, so that the gear of the vehicle is placed in the N or P stage Only at the stopping time (S80: NO), the tire may be warned to warn it to be replaced (S90).

If the wireless communication of the vehicle is not established (NO in S40), the tire monitoring system 170 analyzes the wear of the tire based on the internal data stored therein (S60) The remaining distance is calculated (S70).

Next, the tire monitoring system 170 determines whether the vehicle is running (S80). Specifically, when the electronic control unit 40 receives the stop state of the tire or not, the driver can not immediately change the tire even when the vehicle 1 is running, so that the gear of the vehicle is placed in the N or P stage Only at the stopping time (S80: NO), the tire may be warned to warn it to be replaced (S90).
