타이어 공기압 모니터링 시스템에서의 센서위치 인식장치 및 그 방법{APPARATUS FOR RECOGNIZING POSITION SENSOR IN TIRE PRESSURE MONITORING SYSTEM AND METHOD THEREOF}Sensor position recognition device and method in tire pressure monitoring system {APPARATUS FOR RECOGNIZING POSITION SENSOR IN TIRE PRESSURE MONITORING SYSTEM AND METHOD THEREOF}

본 발명은 타이어 공기압 모니터링 시스템에서의 센서위치 인식장치 및 그 방법에 관한 것으로서, 보다 상세하게는 한 개의 LF기동기 및 TPMS 센서에 두 개의 LF안테나를 사용하여 짧은 시간에 센서위치를 인식하기 위한 타이어 공기압 모니터링 시스템에서의 센서위치 인식장치 및 그 방법에 관한 것이다.
The present invention relates to a sensor position recognition device and method thereof in a tire air pressure monitoring system, and more particularly, tire air pressure for recognizing sensor position in a short time by using two LF antennas in one LF starter and TPMS sensor. An apparatus and method for recognizing sensor position in a monitoring system are provided.

일반적으로, 타이어 압력 감시 시스템(TPMS : Tire Pressure Monitoring System, 이하, 'TPMS 시스템'이라 함)은 자동차에 장착된 타이어의 상태를 운전자에게 알려주어 사전에 사고를 예방할 수 있게 하는 시스템이다. In general, a tire pressure monitoring system (TPMS: TPMS system) is a system that prevents an accident by informing a driver of a tire mounted on a vehicle.

타이어에 장착된 TPMS 센서는 타이어 상태에 대한 정보를 차량에 장착 된 TPMS 제어부로 송신하고, 이 TPMS 제어부는 수신된 각 타이어의 상태를 자동차 계기판 등에 디스플레이하거나 경고음을 발생시켜 운전자에게 알려 준다. The TPMS sensor mounted on the tire transmits information about the tire condition to the TPMS controller mounted on the vehicle, and the TPMS controller displays the state of each tire received on the vehicle dashboard or generates a warning sound to inform the driver.

TPMS 센서에서 송신되는 데이터는 무선주파수(RF) 신호를 사용하여 타이어 압력 상태, 타이어 온도, 센서 ID 등을 전송한다. Data transmitted from the TPMS sensor transmits the tire pressure state, tire temperature, sensor ID, and the like using radio frequency (RF) signals.

이때 TPMS 센서는 항상 활성화(Activation)되어 있는 것이 아니라 특정한 조건이 되거나 또는 외부 명령에 의해서만 활성화가 된다. In this case, the TPMS sensor is not always activated, but becomes a specific condition or activated only by an external command.

차량에 장착된 TPMS 제어부는 타이어의 상태를 정확하게 운전자에게 알려주기 위해서 타이어에 장착되어 있는 TPMS 센서의 ID 위치가 정확하게 등록되어 있어야 한다.
The TPMS control unit mounted on the vehicle must correctly register the ID position of the TPMS sensor mounted on the tire in order to inform the driver of the tire condition accurately.

위에서 설명한 기술은 본 발명이 속하는 기술분야의 배경기술을 의미하며, 종래기술을 의미하는 것은 아니다.
The technology described above refers to the background of the technical field to which the present invention belongs, and does not mean the prior art.

TPMS 시스템은 초기 구동시 각 타이어에 설치되는 TPMS 센서를 개별적으로 인지할 수 있도록 LF기동기를 구비한다. 이 LF기동기는 TPMS 제어부의 제어하에 고유 ID를 가지는 각 TPMS 센서로 웨이크업 신호를 송출하고, 이후 각 TPMS 센서로부터 송출되는 고유 ID와 해당 타이어의 정보를 수신하여 TPMS 제어부로 전송하게 되면 TPMS 제어부에서 센서위치를 인식하게 된다. The TPMS system is equipped with an LF starter so that the TPMS sensor installed on each tire can be individually recognized during initial driving. The LF starter sends a wake-up signal to each TPMS sensor with a unique ID under the control of the TPMS control unit. Then, the LFMS controller receives the unique ID and the tire information transmitted from each TPMS sensor and transmits the information to the TPMS control unit. The sensor location is recognized.

또한, TPMS 센서 내부에 장착된 2축 가속도 센서를 사용하여 차량의 좌우에 장착된 위치를 판단하여 TPMS 제어부로 무선주파수를 이용하여 좌우측 정보를 전송하고 이를 ID 좌우의 그룹으로 센서 ID를 분류한 후 차량의 후방에 장착된 TPMS 제어부를 통하여 각 휠에서 전송되는 전후축상에 무선주파수 파워의 차이를 이용하여 좌우측으로 그룹화된 TPMS 센서의 ID를 전후측으로 구별함으로써 센서위치를 인식하게 된다. In addition, by using the two-axis acceleration sensor mounted inside the TPMS sensor to determine the position mounted on the left and right of the vehicle, and transmits the left and right information by using the radio frequency to the TPMS control unit and classifies the sensor ID into a group of ID left and right Through the TPMS control unit mounted on the rear of the vehicle, the sensor position is recognized by distinguishing the IDs of the TPMS sensors grouped left and right by front and rear using a difference in radio frequency power on the front and rear axes transmitted from each wheel.

그러나 위와 같이 각 타이어에 설치되는 TPMS 센서에 각각 대응되도록 LF기동기를 사용할 경우 시스템의 단가가 상승하게 될 뿐만 아니라 LF기동기와 연결되는 배선이 복잡해지는 문제점이 있으며, 2축 가속도센서를 사용할 경우 장시간 차량을 주행하면서 위치를 추적해야함으로써 센서위치를 인식하는데 많은 시간이 소요되는 문제점이 있다. However, if the LF actuator is used to correspond to the TPMS sensor installed on each tire as described above, the unit price of the system increases and the wiring connected to the LF actuator becomes complicated. There is a problem that it takes a lot of time to recognize the sensor position by tracking the position while driving.

In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout the specification.

도 1은 본 발명의 일 실시예에 따른 타이어 공기압 모니터링 시스템에서의 센서위치 인식장치를 나타낸 구성도이고, 도 2는 본 발명의 일 실시예에 따른 타이어 공기압 모니터링 시스템에서의 센서위치 인식장치에 적용되는 LF기동기와 TPMS 센서의 좌우인식 상태를 설명하기 위한 도면이다. 1 is a block diagram showing a sensor position recognition device in a tire pressure monitoring system according to an embodiment of the present invention, Figure 2 is applied to a sensor position recognition device in a tire pressure monitoring system according to an embodiment of the present invention. Figure is for explaining the left and right recognition state of the LF starter and the TPMS sensor.

도 1에 도시된 바와 같이 본 발명의 일 실시예에 따른 타이어 공기압 모니터링 시스템에서의 센서위치 인식장치는 하나의 LF기동기(30), 두 개의 LF안테나(45)를 갖는 TPMS 센서(40) 및 TPMS 제어부(50)를 포함한다. As shown in FIG. 1, the apparatus for recognizing a sensor position in a tire pressure monitoring system according to an exemplary embodiment of the present invention includes a TPMS sensor 40 and a TPMS having one LF actuator 30 and two LF antennas 45. The control unit 50 is included.

LF기동기(30)는 차량(10)의 중앙 전후방의 어느 일측으로 편중되게 설치되어 웨이크업 신호를 고출력과 저출력으로 발생시킨다. The LF actuator 30 is installed to be biased toward any one side of the center front and rear of the vehicle 10 to generate a wake-up signal with high output and low output.

본 발명의 실시예에서는 도 1에 도시된 바와 같이 LF기동기(30)를 차량(10)의 중앙 전방에 편중되게 설치하였다. In the exemplary embodiment of the present invention, as shown in FIG. 1, the LF actuator 30 is installed in the center front of the vehicle 10.

TPMS 센서(40)는 도 2에 도시된 바와 같이 평행하게 두 개의 LF안테나(45)를 구비할 뿐만 아니라 고유 ID를 갖으며 차륜(20)에 각각 설치되어 LF기동기(30)로부터 발생된 웨이크업 신호를 두 개의 LF안테나(45)를 통해 수신받아 위상차를 분석하여 좌우를 인식하고 좌우인식정보, 고유 ID와 타이어 정보를 전송한다. The TPMS sensor 40 not only has two LF antennas 45 in parallel as shown in FIG. 2, but also has a unique ID and is installed on the wheels 20, respectively, to wake up generated from the LF actuator 30. The signal is received through the two LF antennas 45 to analyze the phase difference to recognize the left and right and transmit the left and right recognition information, unique ID and tire information.

좌우인식은 도 2에 도시된 바와 같이 LF기동기(30)로부터 웨이크업 신호가 발생되면 동일한 자계력선 방향에 대해 차량(10)의 좌우측에 설치된 TPMS 센서(40)의 두 개의 LF안테나(45)는 서로 반대로 위치함에 따라 웨이크업 신호가 180도 상이한 신호로 인식되어 전압극성이 변경되고 이를 통해 TPMS 센서(40)는 좌우를 인식할 수 있게 된다. As shown in FIG. 2, when a wake-up signal is generated from the LF starter 30, two LF antennas 45 of the TPMS sensor 40 installed on the left and right sides of the vehicle 10 for the same magnetic field line direction are As it is positioned opposite each other, the wake-up signal is recognized as a signal that is 180 degrees different, and thus the voltage polarity is changed, thereby allowing the TPMS sensor 40 to recognize left and right.

TPMS 제어부(50)는 LF기동기(30)와 LIN통신이나 CAN통신으로 연결되어 LF기동기(30)로 제어명령을 출력하여 웨이크업 신호가 고출력이나 저출력으로 발생되도록 제어하여 각각 TPMS 센서(40)로부터 입력되는 좌우인식 정보와 고유 ID를 통해 TPMS 센서(40)의 위치를 인식한다. The TPMS control unit 50 is connected to the LF starter 30 by LIN communication or CAN communication, and outputs a control command to the LF starter 30 to control the wake-up signal to be generated at a high output or a low output, respectively, from the TPMS sensor 40. The position of the TPMS sensor 40 is recognized through the left and right recognition information and the unique ID.

즉, LF기동기(30)에서 저출력으로 웨이크업 신호가 발생될 경우에는 LF기동기(30)와 근거리에 있는 전방 TPMS 센서(40)가 웨이크업 되어 좌우인식 정보와 고유 ID를 전송하게 됨으로써 전방 TPMS 센서(40)의 위치를 인식하게 된다. That is, when a wake-up signal is generated at a low output from the LF actuator 30, the front TPMS sensor 40 in the short range and the LF actuator 30 are woken up to transmit left and right recognition information and a unique ID to the front TPMS sensor. The position of 40 is recognized.

반면, LF기동기(30)에서 고출력으로 웨이크업 신호가 발생될 경우에는 LF기동기(30)와 원거리에 있는 후방 TPMS 센서(40)도 웨이크업 되어 좌우인식 정보와 고유 ID를 전송하게 에 따라 후방 TPMS 센서(40)의 위치를 인식하게 된다. On the other hand, when the wake-up signal is generated at a high output from the LF actuator 30, the rear TPMS sensor 40 is also waked up and the rear TPMS 30 is transmitted according to transmission of left and right recognition information and a unique ID. The position of the sensor 40 is recognized.

이와 같이 하나의 LF기동기(30)를 통해 저출력과 고출력으로 웨이크업 신호를 발생시키고 이에 대응하는 TPMS 센서(40)에 대해 전방과 후방을 인식하고 두 개의 LF안테나(45)에서 인식되는 웨이크업 신호의 위상차를 통해 좌우를 인식함으로써 타이어 공기압 모니터링 시스템에서 센서위치를 인식할 수 있다.
As described above, a wakeup signal is generated at a low output and a high output through one LF starter 30, and the front and rear of the corresponding TPMS sensor 40 are recognized, and the wakeup signal is recognized by the two LF antennas 45. By recognizing the left and right through the phase difference of the tire, the sensor position can be recognized in the tire pressure monitoring system.

이와 같이 이루어진 타이어 공기압 모니터링 시스템에서의 센서위치 인식방법에 대해 도 3에 도시된 본 발명의 일 실시예에 따른 타이어 공기압 모니터링 시스템에서의 센서위치 인식방법을 설명한 흐름도를 참조하여 설명하면 다음과 같다. The sensor position recognition method in the tire air pressure monitoring system made as described above will be described with reference to a flowchart describing a sensor position recognition method in the tire air pressure monitoring system according to an embodiment of the present invention shown in FIG. 3.

본 실시예에서 LF기동기(30)는 도 1에 도시된 바와 같이 차량의 중앙 전방에 편중되게 설치하였으며, TMPS 센서(40)는 도 2에 도시된 바와 같이 평행하게 두 개의 LF 안테나(45)가 설치된다. In the present embodiment, the LF actuator 30 is installed in an unbiased front of the vehicle as shown in FIG. 1, and the TMPS sensor 40 includes two LF antennas 45 in parallel as shown in FIG. 2. Is installed.

먼저, LF기동기(30)를 제어하여 웨이크업 신호를 저전력으로 출력시킨다(S10). First, the LF starter 30 is controlled to output a wake-up signal at low power (S10).

이와 같이 LF기동기(30)가 저전력으로 웨이크업 신호를 발생시키게 되면 LF기동기(30)와 근거리에 있는 전방 TPMS 센서(40)가 웨이크업 되면서 두 개의 LF안테나(45)를 통해 위상차를 비교하여 좌우측을 인식하고 좌우측정보, 고유 ID와 타이어정보를 전송한다. As described above, when the LF actuator 30 generates a wake-up signal with low power, the LF actuator 30 and the front TPMS sensor 40 in the short-range wake up while comparing the phase difference through the two LF antennas 45 to the left and right sides. Recognize and transmit left and right information, unique ID and tire information.

그러면 TPMS 제어부(50)에서 이를 수신받아 전방 TPMS 센서(40)의 위치를 인식한다(S20)(S30). Then, the TPMS control unit 50 receives this and recognizes the position of the front TPMS sensor 40 (S20) (S30).

다음으로 LF기동기(30)를 제어하여 웨이크업 신호를 고전력으로 출력시킨다(S40). Next, the LF starter 30 is controlled to output a wake-up signal at high power (S40).

이와 같이 LF기동기(30)가 고전력으로 웨이크업 신호를 발생시키게 되면 LF기동기(30)와 원거리에 있는 후방 TPMS 센서(40)도 웨이크업 되면서 두 개의 LF안테나(45)를 통해 위상차를 비교하여 좌우측을 인식하고 좌우측정보, 고유 ID와 타이어정보를 전송한다. As described above, when the LF actuator 30 generates a wake-up signal at high power, the LF actuator 30 and the rear TPMS sensor 40 are also waked up, and the phase difference is compared through the two LF antennas 45 to the left and right sides. Recognize and transmit left and right information, unique ID and tire information.

그러면 TPMS 제어부(50)에서 이를 수신받아 이미 인식된 전방 TPMS 센서(40)의 신호를 무시하고 후방 TPMS 센서(40)에 대해 위치를 인식한다(S50)(S60). Then, the TPMS controller 50 receives the received signal, ignores the signal of the front TPMS sensor 40 already recognized, and recognizes the position of the rear TPMS sensor 40 (S50) (S60).

이와 같이 LF기동기(30)의 웨이크업 신호의 전계강도를 저출력과 고출력으로 조절하면서 발생시킴으로써 전방과 후방을 인식하고 두 개의 LF안테나(45)를 통해 수신되는 웨이크업 신호의 위상차를 통해 좌우를 인식함으로써 하나의 LF기동기(30)와 두 개의 LF안테나(45)를 통해 TPMS 센서(40)의 위치를 인식하게 된다.
As described above, the electric field strength of the wake-up signal of the LF starter 30 is adjusted to low and high power to recognize the front and rear sides, and the left and right are recognized through the phase difference of the wake-up signals received through the two LF antennas 45. By doing so, the position of the TPMS sensor 40 is recognized through one LF actuator 30 and two LF antennas 45.
