Abstract
Description
The present invention relates to a tire air pressure monitoring system and a method thereof, and more particularly to a tire air pressure monitoring system and method for monitoring the tire pressure state by monitoring the tire pressure state.
In general, the vehicle is equipped with a device for improving the tire durability and braking force by maintaining the proper air pressure and temperature of the tire through an automatic detection sensor attached to the tire. Such a device is commonly referred to as a Tire Pressure Monitoring System (TPMS).
1 is a configuration diagram showing a schematic overall configuration of a conventional TPMS.
Referring to FIG. 1, a conventional tire inflation pressure monitoring system (TPMS) measures the inflation pressure of the
In addition, the
Accordingly, it is an object of the present invention to provide a tire air pressure monitoring system that does not affect the wheel balance and does not require periodic replacement of the battery.
Another object of the present invention is to provide a method for monitoring tire air pressure.
Tire pressure monitoring system of the present invention for achieving the above object, the sensor unit is installed on the wheel axle of the vehicle, the sensor unit for measuring the distance value from the installed position to the ground, and the measured distance value to a predetermined number of sampling Collecting and calculating an average value of the collected distance values, comparing the calculated average value with a preset reference value, and outputting the electronic control unit for determining whether the tire is in an abnormal state and providing the driver with the information for determining the abnormality. It includes an information output unit.
According to another aspect of the present invention, there is provided a method for monitoring tire air pressure, the method comprising: measuring a distance value from a position at which the sensor is installed to the ground through a sensor installed at a wheel shaft of a vehicle; Sampling the distance value from the sensor by a predetermined number, calculating an average value of the distance values sampled by the predetermined number, comparing the calculated average value with a reference value, and determining whether an abnormality is obtained according to a comparison result. And receiving, by the cluster, information determining the abnormality and outputting the determined information to the driver.
According to the present invention, unlike the conventional case in which the sensor component for measuring the air pressure of the tire is mounted in the tire, in the present invention, the wheel balance performance can be improved by mounting the wheel axle for supporting and fixing the tire, resulting in traveling. Stability can be improved.
In addition, unlike the related art, in which the design of the battery is necessary to transmit tire air pressure measured data in an RF signal manner, the present invention does not require replacement of the battery, thereby improving work convenience of the monitoring operator.

2 is a block diagram showing the overall configuration of a TPMS according to an embodiment of the present invention.
3 is a flow chart illustrating a method of monitoring the air pressure of a tire using the system shown in FIG. 2.
The present invention provides a method for reducing the performance of the wheel balance and solving the conventional problem that the replacement of the battery is frequently required.
To this end, in the present invention, an ultrasonic sensor is provided, and the ultrasonic sensor is mounted on a tire shaft not fixed to the tire but fixed to the tire shaft. Using this ultrasonic sensor, distance data from the position where the ultrasonic sensor is mounted to the ground is calculated. In the present invention, the tire height pressure state is monitored using the calculated height data, the presence of an abnormality is detected, and the driver is notified of this.
By doing so, the present invention can improve the wheel balance performance, consequently increase the driving stability, and it is possible to provide a technical effect that can improve the convenience of the monitoring operation because no replacement of the battery is required.
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are assigned to the same components as much as possible even though they are shown in different drawings. In the following description of the embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

As described above, the TPMS 100 according to an embodiment of the present invention minimizes errors generated from irregular ground by using an average value using a moving average when driving a vehicle. In addition, the TPMS 100 according to an embodiment of the present invention determines the distance from the ground when the tire is in a normal state when injecting tire air pressure, and then sets the distance from the ground when the tire is in an abnormal state according to the tire specification (wheel size, flat ratio). Can be. In addition, the TPMS 100 according to an embodiment of the present invention determines the distance to the ground at 500 ms intervals while driving, obtains an average value using the latest 10 sample data, and determines whether the tire is in a normal state.
As a result, as in the embodiment of the present invention, when the distance from the ground is determined, the distance between the ground and the irregular road can be minimized, and can be used in general driving and high speed driving in the same way.
3 is a flowchart illustrating a method of monitoring tire air pressure using the TPMS shown in FIG. 2. To aid in the understanding of the description, reference may be made to FIG. 2 together.
Referring to FIG. 3, first, an initialization process of an average value of tire inflation pressures calculated based on previously sampled distance data is performed (S310). Here, the step of setting the reference value indicating the abnormal range of the tire inflation pressure or the normal value of the tire inflation pressure through the
Subsequently, the process of periodically measuring the distance value from the mounting position to the ground by the
Subsequently, the distance value measured periodically is sampled by a specific number, and an average value calculation process for the sampled distance value is performed (S330).
Subsequently, a process of comparing the calculated average value with the reference value is performed (S340). For example, when the average value is larger than the reference value, the
If, as a result of the comparison operation, the average value is smaller than the reference value, the
The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
