Description
본 발명은 차량에 관한 것으로, 특히 자동변속기가 장착된 차량에 있어서 차속 리드 스위치를 삭제하고 입출력 RPM을 계산하여 차속을 감지할 수 있도록 한 자동변속기 장착차량의 차속감지 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle, and more particularly, to a vehicle speed detecting apparatus for a vehicle equipped with an automatic transmission, in which a vehicle speed reed switch is deleted and an input / output RPM is calculated to detect the vehicle speed.
종래 자동변속기장착 차량은 시프트 패터 맵(shift patter map)을 구성하기 위한 변속기의 입력 및 출력 RPM값을 센서를 이용하여 읽고 있다.BACKGROUND ART [0002] A conventional vehicle equipped with an automatic transmission reads input and output RPM values of a transmission for configuring a shift patter map by using a sensor.
따라서, 클러스터에 자촉을 표시하기 위하여 변속기의 차동기어(differnetial gear)부근에 차속 리드스위치가 별도로 장착되어 있어 원가가 증가하게 되는 문제가 있었다.Therefore, there is a problem in that the cost increases because the vehicle speed reed switch is separately mounted near the differential gear of the transmission in order to display the magnetic head on the cluster.
본 발명은 이와같은 종래의 문제점을 해결하기 위하여 안출한 것으로, 자동변속기의 시프트 패턴 맵을 설정하기 위해 PG(PULSE GENERATOR)-B센서에서 출력 RPM을 감지하여 이를 이용하여 차속을 계산하고 그 값을 운전석앞에 차속으로 표시하면 차속 센서를 삭제하게 되므로 원가절감을 얻을 수 있도록 한 자동변속기 장착차량의 차속감지 장치를 제공하는데 그 목적이 있다.The present invention has been made to solve such a conventional problem, in order to set the shift pattern map of the automatic transmission by detecting the output RPM from the PG (PULSE GENERATOR) -B sensor and calculate the vehicle speed using the value and calculate the value If the vehicle speed sensor is displayed in front of the driver's seat, the vehicle speed sensor is deleted. Therefore, the object of the present invention is to provide a vehicle speed detection device for a vehicle equipped with an automatic transmission that can reduce cost.
이와 같은 목적을 달성하기 위한 본 발명은 TPS(트로틀 포지션 센서), 펄스를 발생시키는 PG-B와, 상기 TPS와 PG-B로부터 입력되는 데이타에 따라 해당되는 제어를 수행하는 TCU, 상기 TCU의 제어에 의해 차속을 표시하는 차속표시장치로 구성함을 특징으로 한다.In order to achieve the above object, the present invention provides a TPS (throttle position sensor), a PG-B generating a pulse, a TCU performing a corresponding control according to data input from the TPS and the PG-B, and control of the TCU. And a vehicle speed display device for displaying the vehicle speed.

도 2는 본 발명의 동작흐름도이다2 is a flow chart of the present invention.

3:TCU4:차속표시장치3: TCU4: Vehicle speed display device
이하, 본 발명의 실시예를 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 블록도로, 트로틀 포지션을 감지하는 TPS(1)와, 펄스를 발생시키는 PG-B(2)와, 상기 TPS(1)와 PG-B(2)로부터 입력되는 데이타에 따라 해당되는 제어를 수행하는 TCU(3)와, 상기 TCU(3)의 제어에 의해 차속을 표시하는 차속표시장치(5)를 구비하여 구성된다.1 is a block diagram of the present invention, in which a TPS 1 detecting a throttle position, a PG-B 2 generating a pulse, and data input from the TPS 1 and PG-B 2 are shown. And a vehicle speed display device (5) for displaying a vehicle speed under the control of the TCU (3).
이와같이 구성된 본 발명은 PG-B(2)에서 감지한 터어빈 회전속도를 가지고 차속을 계산하면,The present invention configured as described above calculates the vehicle speed with the turbine rotation speed detected by the PG-B (2),
여기서, V=차속Where V = vehicle speed
N0=터어빈 회전속도N0 = Turbine Rotational Speed
i T j = j 단 변속기i T j = j gearbox
i T F = 트랜스퍼 기어비i T F = transfer gear ratio
i F = 종감속비i F = reduction ratio
NT = 변속기 효율NT = transmission efficiency
RT = 타이어 하중 반경이다.RT = tire load radius.
한편, 토오크 컨버터가 록-업(LOCK-UP)상태인 경우는,On the other hand, when the torque converter is in the lock-up state,
여기서, NE는 엔진의 회전속도(RPM)를 나타내며 PG-B(2)에서 읽은 터어빈 회전수를 이용하여 차속을 구하고 이 값을 클러스터에 있는 차속 디스플레이에 연결하면 차속 리드 스위치가 필요 없어지게 된다.Here, N E represents the engine speed (RPM). If the vehicle speed is obtained using the turbine speed read from PG-B (2), and this value is connected to the vehicle speed display in the cluster, the vehicle speed reed switch is unnecessary. .
댐퍼스위치 록업인가를 판단하여 맞으면 상기 식(2)로 차속값을 계산하고, 틀리면 상기 식(1)로 차속값을 계산한다.If it is determined that the damper switch is locked up, the vehicle speed value is calculated using Equation (2) above, and the vehicle speed value is calculated using Equation (1) above.
이상에서 설명한 바와 같은 본 발명은 자동변속기 장착 차량에 있어서, 시프트 패턴 맵을 설정하기 위해 PG-B센서에서 출력 RPM을 감지하여 이를 이용하여 차속을 계산하고 그 값을 운전석앞의 클러스터에 차속으로 표시하면 별도의 차속센서를 사용할 필요가 없어지므로 원가를 절감할 수 있는 효과가 있다.According to the present invention as described above, in a vehicle equipped with an automatic transmission, in order to set a shift pattern map, the output RPM is detected by the PG-B sensor, the vehicle speed is calculated using the calculated RPM, and the value is displayed on the cluster in front of the driver's seat. This eliminates the need to use a separate vehicle speed sensor, reducing cost.
