이하에서는 본 발명에 따른 바람직한 실시 예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment according to the present invention will be described in detail.

본 발명에 따른 차량용 제어시스템은 도 1에 도시한 바와 같이, 차량 각바퀴(FL,FR,RL,RR)의 타이어 압력을 검출하여 무선 송신하는 TPMS 송신부(11a,11b,11c,11d)들과, TPMS 송신부(11a,11b,11c,11d)를 통해 송신되는 데이터를 수신하는 TPMS 수신부를 포함하는 제어유닛(20)과, 제어유닛(20)으로부터 전송되는 차량의 각 타이어 압력정보와 각종 차량의 상태정보를 표시하는 디스플레이부(13)를 구비한다.As shown in FIG. 1, the control system for a vehicle according to the present invention includes TPMS transmitters 11a, 11b, 11c, and 11d that detect and wirelessly transmit tire pressures of vehicle wheels FL, FR, RL, and RR. And a control unit 20 including a TPMS receiver for receiving data transmitted through the TPMS transmitters 11a, 11b, 11c, and 11d, and each tire pressure information of the vehicle transmitted from the control unit 20 and various vehicles. A display unit 13 for displaying status information is provided.

TPMS 송신부(11a,11b,11c,11d)는 차량의 각 바퀴(FL,FR,RL,RR)의 타이어 내부에 설치되어 타이어의 압력을 검출하는 센서(미도시)를 포함하며, 이러한 센서를 통하여 검출된 데이터를 제어유닛(20)으로 무선 송신한다.The TPMS transmitters 11a, 11b, 11c, and 11d include sensors (not shown) installed inside the tires of the wheels FL, FR, RL, and RR of the vehicle to detect the pressure of the tires. The detected data is wirelessly transmitted to the control unit 20.

제어유닛(20)은 내장된 TPMS 수신부가 TPMS 송신부(11a,11b,11c,11d)로부터 전송되는 데이터를 수신하고, 이러한 정보를 디스플레이부(13)를 통해 운전자에게 경고하거나 차량의 제어를 위해 이용한다. 이러한 제어유닛(20)은 도면에 도시하지 는 않았지만, 전반적인 차량 자세제어를 수행하기 위한 ESP 시스템이 일체화된 형태로 구성될 수 있다. EPS시스템은 차량의 자세제어를 위한 각종 센서들, 이 센서들의 감지정보를 토대로 차량의 상태를 판단하는 EPS제어부, 그리고 엔진구동력과 제동력을 제어하는 EPS 구동부를 포함하는 형태일 수 있다. EPS 시스템과 TPMS 시스템이 일체화된 제어유닛에 대해서는 본 발명의 배경기술로 제시한 대한민국 공개특허공보 2007-62277호에 상세히 설명되어 있으므로 여기서는 이에 대한 설명을 생략하기로 한다.The control unit 20 receives data transmitted from the TPMS transmitters 11a, 11b, 11c, and 11d by the built-in TPMS receiver, and warns the driver through the display unit 13 or uses the information to control the vehicle. . Although not shown in the drawing, the control unit 20 may be configured in an integrated form of an ESP system for performing overall vehicle attitude control. The EPS system may include various sensors for controlling the attitude of the vehicle, an EPS controller which determines the state of the vehicle based on the sensing information of the sensors, and an EPS driver which controls the engine driving force and the braking force. The control unit in which the EPS system and the TPMS system are integrated is described in detail in Korean Patent Publication No. 2007-62277, which is presented as a background art of the present invention, and thus description thereof will be omitted.

한편, 제어유닛(20)은 도 2에 도시한 바와 같이, 전술한 TPMS 수신부를 포함하여 구성한 제어회로부(21, 회로기판)와, 이 제어회로부(21)를 수용하는 케이스(30)를 구비한다. 또 케이스(30)는 상호 합체되는 상부케이스(31)와 하부케이스(32)를 포함한다. 그리고 상부케이스(31)에는 TPMS 송신부(11a,11b,11c,11d)와 무선통신을 위한 안테나(40)가 설치된다. 안테나(40)는 TPMS 송신부(11a,11b,11c,11d)로부터 데이터를 수신하여 제어회로부(21)의 TPMS 수신부로 전송한다.Meanwhile, as shown in FIG. 2, the control unit 20 includes a control circuit unit 21 (circuit board) configured to include the above-described TPMS receiver unit, and a case 30 accommodating the control circuit unit 21. . In addition, the case 30 includes an upper case 31 and a lower case 32 which are integrated with each other. In addition, the upper case 31 is provided with antennas 40 for wireless communication with the TPMS transmitters 11a, 11b, 11c, and 11d. The antenna 40 receives data from the TPMS transmitters 11a, 11b, 11c, and 11d and transmits the data to the TPMS receiver of the control circuit unit 21.

상부케이스(31)는 절연이 가능한 수지재질로 마련되고, 안테나(40)는 이러한 상부케이스(31) 내에 매입된다. 즉 안테나(40)는 도 2 내지 도 4에 도시한 바와 같이, 상부케이스(31)의 측면부 내에 매입되며, 측면부 내측을 따라 길게 연장된 형태이다. 또 안테나(40)는 일단이 상부케이스(31) 내측으로 연장되어 제어회로부(21)와 연결되는 연결부(41)를 구비한다.The upper case 31 is provided with a resin material that can insulate, and the antenna 40 is embedded in the upper case 31. That is, the antenna 40 is embedded in the side portion of the upper case 31, as shown in Figures 2 to 4, and extends along the inner side of the side portion. In addition, the antenna 40 has a connecting portion 41, one end of which extends into the upper case 31 to be connected to the control circuit 21.

상부케이스(31)는 통상의 수지재 사출성형방식을 통하여 제조할 수 있고, 안 테나(40)는 이처럼 사출성형을 통하여 상부케이스(31)를 제조하는 과정에서 상부케이스(31)에 인서트방식으로 매입시킬 수 있다.The upper case 31 may be manufactured by a conventional resin injection molding method, and the antenna 40 may be inserted into the upper case 31 in the process of manufacturing the upper case 31 by injection molding. We can purchase.

이처럼 안테나(40)를 상부케이스(31)와 일체로 제조하면, 안테나(40)를 상부케이스(31)의 측면부를 따라 길게 매입시킬 수 있으므로 TPMS 송신부(11a,11b,11c,11d)로부터 송신되는 신호를 원활히 수신할 수 있다. 또 안테나(40)가 상부케이스(31)와 일체화되기 때문에 제어시스템의 구성을 위한 비용을 줄일 수 있다. 제어유닛(20)을 차량에 설치할 때도 별도의 안테나를 설치하지 않아도 되므로 차량에 설치하기가 용이해진다.When the antenna 40 is integrally manufactured with the upper case 31 as described above, the antenna 40 can be embedded along the side of the upper case 31 so that the antenna 40 is transmitted from the TPMS transmitters 11a, 11b, 11c, and 11d. The signal can be received smoothly. In addition, since the antenna 40 is integrated with the upper case 31, the cost for the configuration of the control system can be reduced. Even when the control unit 20 is installed in the vehicle, it is not necessary to install a separate antenna, so it is easy to install in the vehicle.
