[산업상 이용 분야][Industrial use]
본 고안은 자동차의 주행속도를 감지하는 감지구조에 관한 것으로, 좀더 구체적으로는 차속센서의 감지구조를 개선하여 원가절감을 꾀할 수 있도록 한 것이다.The present invention relates to a sensing structure for detecting a driving speed of a vehicle, and more specifically, to reduce cost by improving a sensing structure of a vehicle speed sensor.
[종래기술][Private Technology]
일반적으로 차속센서는 제 1 도에 도시된 바와 같이 변속기의 출력단이나 구동휠에 홀센서(Hole Sensor)(10)를 장착하고, 이 홀센서(10)에서 감지한 입력신호를 전자제어유닛(Electronic Control Unit : ECU)(11)와 변속제어장치(Transmission Control Unit : TCU)(12) 및 차속미터(Cluster)(13) 각각에 보내도록 하는 구조로서 차속을 감지하도록 구성하였다.In general, the vehicle speed sensor is equipped with a Hall sensor (10) to the output terminal or the driving wheel of the transmission, as shown in Figure 1, and the input signal detected by the Hall sensor 10 (Electronic Control Unit (Electronic) The control unit (ECU) 11, the transmission control unit (TCU) 12 and the vehicle speed meter (Cluster) 13 to send to each of the structure is configured to detect the vehicle speed.
[종래 기술의 문제점][Problems with Prior Art]
그런데 종래와 같이 차속을 감지하는 홀센서(10)는 그 감지한 신호를 구형파로 정형시켜서 이를 ECU(11)와 TCU(12) 및 차속미터(13) 각각에 보내므로서 차속을 정밀하게 감지할 수 있는 반면에, 상기 홀센서(10)는 그 가격이 매우 고가이기 때문에 차속센서 시스템 자체가 비싸지는 단점이 있었다.However, the hall sensor 10 for detecting a vehicle speed, as in the related art, shapes the detected signal into a square wave and sends it to each of the ECU 11, the TCU 12, and the vehicle speed meter 13 to accurately detect the vehicle speed. On the other hand, the Hall sensor 10 has a disadvantage that the vehicle speed sensor system itself is expensive because the price is very expensive.
[고안이 해결하고자 하는 과제][Problem to Solve]
본 고안은 종래와 같이 차속센서 시스템이 고가인 점을 감안하여 차속을 아날로그(Analog)신호로 정밀하게 감지하는 크랭크샤프트 포지션 센서(Crankshaft Position Sensor : CPS)를 이용하여 차속을 감지할 수 있도록 하며, 또한 CPS의 아날로그 신호가 ECU에 입력된 다음 TCU 및 차속센서에는 디지탈(Digital)신호로 출력시킬 수 있게 하는 구조로서 차속센서 시스템을 구성한 것인데, 상기 CPS는 비교적 저가로 구입할 수 있으므로서 차속센서 시스템의 제작비를 절감시킬 수 있도록 하는데 목적을 두고 고안한 것이다.The present design allows the vehicle speed to be detected using a crankshaft position sensor (CPS) that accurately detects the vehicle speed as an analog signal in consideration of the fact that the vehicle speed sensor system is expensive as in the prior art. In addition, the analog signal of the CPS is input to the ECU, and then the TCU and the vehicle speed sensor can be output as a digital signal, thereby constructing a vehicle speed sensor system. It is designed for the purpose of reducing production costs.
[과제를 해결하기 위한 수단][Means for solving the problem]
본 고안은 상기와 같은 목적을 달성하기 위하여, 크랭크샤프트에 장착되는 센서용 치차의 회전수를 감지하여 ECU로 전송하는 CPS와; 상기 CPS로 부터 감지되어 입력된 아날로그신호를 디지탈신호로 변환시켜 TCU와 차속미터에 공급하는 ECU를 포함하여 구성함을 특징으로 하는 것이다.The present invention is to achieve the above object, CPS for detecting the number of revolutions of the gear for the sensor mounted on the crankshaft and transmits to the ECU; It is characterized in that it comprises a ECU for converting the analog signal detected and input from the CPS to a digital signal to supply to the TCU and the vehicle speed meter.
[실시예]EXAMPLE
본 고안의 실시예를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안의 차속센서 감지구조를 나타내는 계통도로서,2 is a system diagram showing a vehicle speed sensor detection structure of the present invention,
도면부호 1은 CPS(Crankshaft Position Sensor)를 나타내는 것으로, 상기 CPS(1)는 크랭크샤프트에 장착되어 회전하는 센서용 치차(2)의 회전수를 감지하는 장치로서, 센서용 치차(2)는 그 감지한 것을 아날로그 신호로 하여 ECU(3)에만 보낸다.Reference numeral 1 denotes a Crankshaft Position Sensor (CPS), wherein the CPS (1) is a device mounted on the crankshaft to detect the rotational speed of the rotating gear tooth (2), the sensor tooth (2) The detected signal is sent to the ECU 3 as an analog signal.
상기 ECU(3)는 센서용 치차(2)의 아날로그 신호를 구형 정형파로 정형하여 디지탈신호로 변환시킨 다음 TCU(4) 및 차속미터(5)에 각각 보내도록 구성하므로서 상기 TCU(4) 및 차속미터(5)는 CPS(1)가 감지한 차속을 정확히 읽게 되는 것이다.The ECU 3 is configured to convert an analog signal of the sensor gear 2 into a square square wave, convert it to a digital signal, and then send the analog signal to the TCU 4 and the vehicle speed meter 5, respectively. The meter 5 accurately reads the vehicle speed sensed by the CPS 1.
[효과][effect]
상기와 같은 본 발명에 의하면 센서용 치차의 회전수를 CPS가 감지하여 아날로그 신호로 보내면 ECU가 이를 받아 디지탈 신호로 변환하여 TCU 및 차속미터에 보내므로서 차속을 정확히 감지할 수 있으므로서 종래와 같이 디지탈신호를 감지하는 TCU와 차속미터가 차속을 감지할 수 있게 하기 위해 고가의 홀센서를 사용하는 대신에 홀센서에 비하여 가격이 저렴한 CPS를 사용하더라도 홀센서와 같은 효과를 얻을 수 있므로서 차속감지 시스템의 가격을 종래에 비하여 현저히 절감시키는 경제적인 효과를 가져다 주는 실용적인 고안인 것이다.According to the present invention as described above, when the CPS detects the number of revolutions of the gear for the sensor and sends it as an analog signal, the ECU receives it and converts it into a digital signal and sends it to the TCU and the speed meter so that the vehicle speed can be accurately detected. Instead of using expensive Hall sensors to allow the TCU and the speed meter to detect the digital signal, the same effect as the Hall sensors can be achieved even if CPS is cheaper than Hall sensors. It is a practical design that brings the economic effect of significantly reducing the price of the sensing system compared to the conventional.
