A third adder 15 that adds a multiplier 14, an output of the multiplier 14, and an output of the second adder 13, and a buffer that buffers the output of the third adder 15 to the ECU. It consists of (16).

도 3은 상기 도 2의 구성을 간략화한 것으로,크게 온도를 보정해주는 온도보상부(30)와,상기 온도보상부(30)에 연결되어 기울기와 Y절편을 보정해주는 리니어러티 보상부(31)로 구성된 것을 나타낸 것이다.3 is a simplified view of the configuration of FIG. 2, a temperature compensator 30 for greatly correcting a temperature, and a linear compensator 31 connected to the temperature compensator 30 to correct a slope and a Y-intercept. It is composed of.

이와같이 구성된 본 발명은 차고센서에 의해 감지된 차고에 관한 데이터가 마이크로콘트롤부(3)에 입력되고 있는 상태에서 현재온도에 관한 아날로그 신호가 보정 모듈(4)의 A/D콘버터(10)를 통하여 디지탈 신호로 변환된 후 PROM(11)에 입력된다.According to the present invention configured as described above, the analog signal relating to the current temperature is inputted through the A / D converter 10 of the correction module 4 while the data related to the garage sensed by the garage sensor is being input to the microcontrol unit 3. The signal is converted into a digital signal and input to the PROM 11.

따라서, PROM(11)에서는 기입력된 기준데이터와 상기 A/D콘버터(10)를 통하여 입력된 온도데이터를 비교하여 기울기 보정 데이터(△C1)와 Y절편(△C2)을 출력한다.Accordingly, the PROM 11 compares the input reference data with the temperature data input through the A / D converter 10 and outputs the tilt correction data ΔC1 and the Y segment ΔC2.

이와같이 출력된 기울기 보정 데이터(△C1)와 Y절편(△C2)이 제1,제2가산기(12)(13)에서 상수(C10)(C00)와 더해져 각각 곱셈기(14)와 제3가산기(15)에 입력된다.The tilt correction data DELTA C1 and the Y intercept DELTA C2 thus output are added to the constants C10 and C00 in the first and second adders 12 and 13, respectively, to the multiplier 14 and the third adder ( 15) is entered.

그러면 곱셈기(14)에서는 상기 제1가산기(12)로부터 입력되는 신호와 차고센서로부터의 신호를 곱하여 출력하며,또한 제3가산기(15)에서는 상기 제2가산기(13)의 출력신호와 상기 곱셈기(14)로부터 입력되는 신호를 가산하여 출력한다.The multiplier 14 multiplies and outputs the signal input from the first adder 12 and the signal from the height sensor, and the third adder 15 outputs the output signal of the second adder 13 and the multiplier ( The signal input from 14) is added and output.

이렇게 제3가산기(15)를 통하여 출력되는 신호는 버퍼(16)를 통하여 ECU로 출력되는데, 이때 ECU로 출력되는 신호는 온도 및 리니어러티(기울기,절편)가 보정된 안정된 신호이기 때문에 온도변화에 따른 에러를 방지할 수 있게 되는 것이다.The signal output through the third adder 15 is output to the ECU through the buffer 16. At this time, the signal output to the ECU is a stable signal in which temperature and linearity (tilt and intercept) are corrected. This can prevent errors.

이상에서 설명한 바와같은 본 발명은 기존 방식에 마이크로 콘트롤러를 더 추가하여 센서의 출력불량원인인 온도,리니어러티를 보상해 줌으로써 온도변화에 대한 출력변화의 에러를 방지할 수 있는 효과가 있다.As described above, the present invention has an effect of preventing an error in output change due to temperature change by adding a microcontroller to the existing method to compensate for temperature and linearity, which are causes of output failure of the sensor.
