역회전력을 사용한 차량용 팬-모터의 제어 방법{Method of controlling fan-motor for vehicles wherein reverse torque is used}Method of controlling fan-motor for vehicles wherein reverse torque is used}

본 발명은, 차량용 팬-모터의 제어 방법에 관한 것으로서, 보다 상세하게는, 차량의 냉각-팬을 구동하는 차량용 팬-모터의 제어 방법에 관한 것이다.The present invention relates to a method for controlling a vehicle fan-motor, and more particularly, to a method for controlling a vehicle fan-motor for driving a cooling-fan of a vehicle.

차량의 냉각-팬은 차량의 엔진 온도 예를 들어, 냉각수 온도에 따라 수시로 구동되어 엔진-라디에이터 등으로의 송풍을 수행한다. 이와 같은 냉각-팬을 구동하는 종래의 차량용 팬-모터의 제어 방법 예를 들어, 2002년 일본 공개특허 공보 제233185호에 의하면, 팬-모터 자체의 제어가 정밀하게 수행될 수 있다. 하지만, 팬-모터가 정지되는 경우, 냉각 팬에 인가되는 관성력에 의하여 팬-모터가 냉각 팬과 함께 강제적으로 회전된다. 이에 따라, 팬-모터의 구동 전원이 오프(Off)되더라도 팬-모터와 냉각 팬에서 수 초 동안 소음이 발생되는 문제점이 있다. 이러한 문제점은 브러쉬(brush)가 구비된 브러쉬 모터에서 더욱 심화된다.The cooling fan of the vehicle is often driven according to the engine temperature of the vehicle, for example, the coolant temperature, to blow air to the engine-radiator or the like. A control method of a conventional vehicle fan-motor for driving such a cooling fan, for example, according to Japanese Patent Laid-Open No. 233185, 2002, the control of the fan-motor itself can be performed precisely. However, when the fan-motor is stopped, the fan-motor is forcibly rotated together with the cooling fan by the inertia force applied to the cooling fan. Accordingly, even when the driving power of the fan-motor is off, noise is generated for several seconds in the fan-motor and the cooling fan. This problem is exacerbated in brush motors equipped with brushes.

본 발명의 목적은, 차량용 팬-모터가 정지되는 시점으로부터 발생되는 소음을 줄일 수 있는 차량용 팬-모터의 제어 방법을 제공하는 것이다.An object of the present invention is to provide a control method of a vehicular fan-motor which can reduce the noise generated from the point of time at which the vehicular fan-motor is stopped.

상기 목적을 이루기 위한 본 발명은, 차량의 냉각-팬을 구동하는 차량용 팬-모터의 제어 방법으로서, 역회전력 제어 및 정지 제어 단계들을 포함한다. 상기 역회전력 제어 단계에서는, 상기 팬-모터의 정지 시점이 되면, 상기 팬-모터에 역회전력이 인가된다. 상기 정지 제어 단계에서는, 상기 역회전력 인가 단계의 수행 후에 상기 팬-모터가 정지된다.The present invention for achieving the above object is a control method of a vehicular fan-motor for driving a cooling-fan of a vehicle, comprising reverse rotational power control and stop control steps. In the reverse power control step, when the fan motor is stopped, reverse power is applied to the fan motor. In the stop control step, the fan-motor is stopped after performing the reverse rotation power application step.

본 발명의 상기 제어 방법에 의하면, 상기 역회전력 제어 단계에서 상기 냉각 팬의 관성력이 상쇄된다. 이에 따라, 상기 정지 제어 단계에서, 상기 팬-모터 및 상기 냉각 팬에서 발생되는 소음이 줄어들 수 있다.According to the control method of the present invention, the inertia force of the cooling fan is canceled in the reverse power control step. Accordingly, in the stop control step, noise generated in the fan-motor and the cooling fan can be reduced.

이하, 본 발명에 따른 바람직한 실시예가 상세히 설명된다.Hereinafter, preferred embodiments according to the present invention will be described in detail.

도 1을 참조하면, 본 발명의 제어 방법을 수행하기 위한 차량의 환풍 제어 시스템은 마이크로-제어기(10), 압축기-압력 검출기(11), 이.이.피.롬(12, Electrically Erasable Programmable Read Only Memory), 냉각수-온도 검출기(13), 모터 구동 회로(14), 팬-모터(M), 구동 전류 검출기(15), 주행-속도 검출기(SS) 및 인터페이스 회로(16)를 포함한다.Referring to FIG. 1, a ventilation control system of a vehicle for performing the control method of the present invention includes a micro-controller 10, a compressor-pressure detector 11, and an E.P. rom 12. Only Memory), coolant-temperature detector 13, motor drive circuit 14, fan-motor M, drive current detector 15, travel-speed detector (SS) and interface circuit 16.

압축기-압력 검출기(11)는 차량의 에어콘에 포함된 압축기의 압력을 검출하여, 압축기-압력 데이터를 마이크로-제어기(10) 예를 들어, 엔진 제어 소자에 입력시킨다. 냉각수-온도 검출기(13)는 엔진 냉각수의 온도를 검출하여 냉각수-온도 데이터를 마이크로-제어기(10)에 입력시킨다. 주행-속도 검출기(SS)는 차량의 주행 속도를 검출하여 인터페이스 회로(16)로써 차량 속도 데이터를 마이크로-제어기(10)에 입력시킨다.The compressor-pressure detector 11 detects the pressure of the compressor included in the air conditioner of the vehicle and inputs the compressor-pressure data to the micro-controller 10, for example, the engine control element. The coolant-temperature detector 13 detects the temperature of the engine coolant and inputs coolant-temperature data to the micro-controller 10. The travel-speed detector SS detects the travel speed of the vehicle and inputs the vehicle speed data to the micro-controller 10 via the interface circuit 16.

이.이.피.롬(12)에는 마이크로-제어기(10)가 사용할 회전력 데이터가 룩-업 테이블(Look-Up Table)의 형태로써 저장된다. 보다 상세하게는, 차량의 냉각수 온도, 주행 속도, 및 에어콘의 압축기 압력에 따른 팬-모터의 회전력 데이터가 이.이.피.롬(12)에 저장된다. 여기서, 압축기의 압력이 높아질수록 엔진의 부하율이 높아져서 엔진의 온도가 상승하므로, 회전력의 데이터는 압축기의 압력에 비례한다. 또한, 차량의 냉각수 온도는 엔진의 온도와 비례하므로, 상기 회전력의 데이터는 압축기의 압력에 비례한다. 한편, 차량의 주행 속도는 자연 공냉력에 비례하므로, 상기 회전력의 데이터는 차량의 주행 속도에 반비례한다.In the E.P.rom 12, rotational force data to be used by the micro-controller 10 is stored in the form of a look-up table. More specifically, the rotational force data of the fan-motor according to the coolant temperature of the vehicle, the traveling speed, and the compressor pressure of the air conditioner are stored in the E.P.rom 12. Here, the higher the pressure of the compressor, the higher the load factor of the engine, so that the temperature of the engine rises, so the data of the rotational force is proportional to the pressure of the compressor. In addition, since the cooling water temperature of the vehicle is proportional to the temperature of the engine, the rotational force data is proportional to the pressure of the compressor. On the other hand, since the running speed of the vehicle is proportional to the natural air cooling force, the data of the rotational force is inversely proportional to the running speed of the vehicle.

마이크로-제어기(10)는, 압축기-압력 검출기(11)로부터의 압축기의 압력, 냉각수-온도 검출기(13)로부터의 엔진 냉각수의 온도, 및 주행-속도 검출기(SS)로부터의 차량의 주행 속도에 따른 회전력 데이터를 이.이.피.롬(12)에서 검색하여 모터 구동 회로(14)에 입력시킨다.The micro-controller 10 is adapted to the pressure of the compressor from the compressor-pressure detector 11, the temperature of the engine coolant from the coolant-temperature detector 13, and the running speed of the vehicle from the travel-speed detector SS. The rotational force data thus obtained is retrieved from the E.P.rom 12 and input to the motor drive circuit 14.

모터 구동 회로(14)는 마이크로-제어기(10)로부터의 펄스폭변조(Pulse Width Modulation) 형식의 회전력 신호를 전압 신호로 변환시켜 팬-모터(M)에 인가한다. 냉각 팬은 팬-모터(M)의 구동에 따라 회전한다. 구동 전류 검출기(15)는 모터 구동 회로(14)를 통하여 팬-모터(M)에 흐르는 구동 전류를 검출하여 그 결과 데이터를 마이크로-제어기(10)에 입력시킨다. 이에 따라, 마이크로-제어기(10)는, 팬-모터(M)의 현재 구동 상태를 파악하여, 팬-모터(M)가 목표 회전력에 따라 회전할 수 있도록 모터 구동 회로(14)에 입력되는 회전력의 신호를 조정한다.The motor driving circuit 14 converts a torque signal in the form of Pulse Width Modulation from the micro-controller 10 into a voltage signal and applies it to the fan-motor M. The cooling fan rotates in accordance with the drive of the fan-motor M. The drive current detector 15 detects a drive current flowing in the fan-motor M through the motor drive circuit 14 and inputs the result data into the micro-controller 10. Accordingly, the micro-controller 10 detects the current driving state of the fan-motor M, and the rotational force input to the motor driving circuit 14 so that the fan-motor M can rotate in accordance with the target rotational force. Adjust the signal.

도 1 및 2를 참조하여, 도 1의 마이크로-제어기(10)에 의하여 수행되는 본 발명의 제어 방법을 설명하면 다음과 같다.1 and 2, the control method of the present invention performed by the micro-controller 10 of FIG. 1 will be described.

먼저, 각 동작 조건의 초기화가 수행된다(단계 S21). 다음에, 압축기-압력 검출기(11)로부터의 압축기의 압력, 냉각수-온도 검출기(13)로부터의 엔진 냉각수의 온도, 및 주행-속도 검출기(SS)로부터의 차량의 주행 속도에 따른 회전력 데이터를 이.이.피.롬(12)에서 검색하여 모터 구동 회로(14)에 입력시킨다(단계 S22). 상기한 바와 같이, 압축기의 압력이 높아질수록 엔진의 부하율이 높아져서 엔진의 온도가 상승하므로, 회전력의 데이터는 압축기의 압력에 비례한다. 또한, 차량의 냉각수 온도는 엔진의 온도와 비례하므로, 상기 회전력의 데이터는 압축기의 압력에 비례한다. 한편, 차량의 주행 속도는 자연 공냉력에 비례하므로, 상기 회전력의 데이터는 차량의 주행 속도에 반비례한다.First, initialization of each operating condition is performed (step S21). Next, the rotational force data according to the pressure of the compressor from the compressor-pressure detector 11, the temperature of the engine coolant from the coolant-temperature detector 13, and the traveling speed of the vehicle from the travel-speed detector SS are obtained. The P. ROM 12 is searched for and input to the motor drive circuit 14 (step S22). As described above, the higher the pressure of the compressor, the higher the load factor of the engine, so that the temperature of the engine rises, so that the rotational force data is proportional to the pressure of the compressor. In addition, since the cooling water temperature of the vehicle is proportional to the temperature of the engine, the rotational force data is proportional to the pressure of the compressor. On the other hand, since the running speed of the vehicle is proportional to the natural air cooling force, the data of the rotational force is inversely proportional to the running speed of the vehicle.

다음에, 팬-모터(M)의 정지 시점이 되면(단계 S23), 마이크로-제어기(10)는 수 초 동안 역회전력의 신호를 모터 구동 회로(14)에 입력한다(단계 S24). 이에 따라, 모터 구동 회로(14)는 수 초 동안 팬-모터(M)에 역전압을 인가하고, 팬-모터(M)에서 역회전력이 발생되므로 팬-모터(M)에 의하여 정회전하던 냉각 팬(F)의 관성력이 상쇄된다.Next, when it comes to the stop point of the fan-motor M (step S23), the micro-controller 10 inputs a signal of reverse rotational power to the motor drive circuit 14 for several seconds (step S24). Accordingly, the motor driving circuit 14 applies a reverse voltage to the fan-motor M for a few seconds, and since the reverse power is generated in the fan-motor M, the cooling fan that has been rotated forward by the fan-motor M The inertial force of (F) is canceled.

이어서, 마이크로-제어기(10)가 정지 신호를 모터 구동 회로(14)에 입력함에 따라 모터 구동 회로(14)는 팬-모터(M)를 정지시킨다(단계 S25). 여기서, 상기 역회전력 제어(단계 S28)에 의하여 냉각 팬(F)의 관성력이 상쇄되어 있는 상태이므로, 팬-모터(M) 및 냉각 팬(F)에서 발생되는 소음이 줄어들 수 있다.Then, as the micro-controller 10 inputs a stop signal to the motor drive circuit 14, the motor drive circuit 14 stops the fan-motor M (step S25). Here, since the inertia force of the cooling fan F is canceled by the reverse power control (step S28), the noise generated by the fan-motor M and the cooling fan F can be reduced.

이상 설명된 바와 같이, 본 발명에 따른 차량용 팬-모터의 제어 방법에 의하면, 역회전력이 팬-모터(M)에 인가되어 냉각 팬(F)의 관성력이 상쇄된 후에 팬-모터(M)가 정지된다. 이에 따라, 팬-모터(M) 및 냉각 팬(F)에서 발생되는 소음이 줄어들 수 있다.As described above, according to the control method of the vehicular fan-motor according to the present invention, after the reverse rotational power is applied to the fan-motor M and the inertia force of the cooling fan F is canceled, the fan-motor M Is stopped. Accordingly, noise generated in the fan-motor M and the cooling fan F can be reduced.

본 발명은, 상기 실시예에 한정되지 않고, 첨부된 청구범위에 정의된 발명의 사상 및 범위 내에서 당업자에 의하여 변형 및 개량이 가능하다.The present invention is not limited to the above embodiments, and modifications and improvements may be made by those skilled in the art within the spirit and scope of the invention as defined in the appended claims.
