Description

차량의 안전 파워 윈도우 제어장치 { APPARATUS FOR CONTROLLING SAFETY POWER WINDOWS IN VEHICLES }Vehicle Safety Power Window Control {APPARATUS FOR CONTROLLING SAFETY POWER WINDOWS IN VEHICLES}

본 발명은 차량의 안전 파워 윈도우(Safety Power Window; 이하 SPW라 함) 제어장치에 관한 것이며, 보다 상세히는 지역상호접속망(Local Interconnect Network; 이하, LIN이라 함) 통신 프로토콜을 이용하여 차량의 파워 윈도우를 구동시키도록 된 차량의 SPW 제어장치에 관한 것이다.The present invention relates to a safety power window (SPW) control apparatus of a vehicle, and more particularly, to a power window of a vehicle using a local interconnect network (hereinafter referred to as LIN) communication protocol. It relates to a SPW control device of a vehicle configured to drive the.

공지된 바와 같이, 차량의 SPW는 운전자 또는 조수석이나 차량의 뒷좌석 탑승자가 윈도우스위치를 조작하면 모터의 구동력에 의해 상승 혹은 하강하도록 되어 있다.As is known, the SPW of a vehicle is to be raised or lowered by the driving force of the motor when the driver or the passenger seat or the rear seat occupant of the vehicle operates the window switch.

또한, 상기 SPW를 상승 혹은 하강시키기 위한 하나의 윈도우스위치는 4개의 제어용 와이어를 통해 상기 SPW 구동모터에 직접적으로 연결되어 차량의 SPW를 구동하도록 되어 있다.In addition, one window switch for raising or lowering the SPW is directly connected to the SPW driving motor through four control wires to drive the SPW of the vehicle.

그러나, 상기와 같이 와이어를 통해 윈도우스위치와 SPW 구동모터를 직접 연결하여 SPW를 구동시키는 종래의 SPW 제어장치는, 하나의 SPW 구동모터에 대하여 2개의 전원선 이외에 상기 4개의 와이어가 추가로 연결되기 때문에, 차량의 SPW와 SPW 구동모터의 개수가 증가할 경우 와이어의 수가 비례적으로 증가하여 장치의 무게가 증가하고 전체 배선구조가 복잡해지는 단점이 있을 뿐만 아니라, 이로 인해 복수의 SPW 구동모터 중에서 특정한 SPW 구동모터에 고장이 발생하였을 경우 고장진단이 어려운 문제점이 있다.However, in the conventional SPW control device for driving the SPW by directly connecting the window switch and the SPW driving motor through the wire, the four wires are additionally connected to one SPW driving motor in addition to the two power lines. Therefore, when the number of SPW and SPW driving motor of the vehicle increases, the number of wires increases proportionally, the weight of the device increases and the overall wiring structure becomes complicated. If a failure occurs in the SPW drive motor, it is difficult to diagnose the failure.

따라서, 본 발명의 목적은 공지의 시리얼통신인터페이스(SCI)를 지원하는 LIN 통신 프로토콜을 적용하여 1개의 LIN 통신선으로 복수의 SPW 모터구동모듈을제어함으로써 복수의 파워 윈도우를 구동시키고 상기 SPW 모터구동모듈에 대한 자가진단을 하도록 된 차량의 SPW 제어장치를 제공하는데 있다.Accordingly, an object of the present invention is to apply a LIN communication protocol supporting a known serial communication interface (SCI) to drive a plurality of power windows by controlling a plurality of SPW motor drive module with one LIN communication line and the SPW motor drive module It is to provide a vehicle SPW control device for self-diagnosis.

LIN 인터페이스부(40)는 상기 마스터모듈(30)의 시리얼 SPW 제어신호를 1개의 LIN 통신선(41)을 통하여 상기 4개의 SPW 모터구동모듈(20)로 인가시킨다.The LIN interface unit 40 applies the serial SPW control signal of the master module 30 to the four SPW motor drive modules 20 through one LIN communication line 41.

상기 LIN 인터페이스부(40)는 마스터모듈(30)로부터 출력된 시리얼 SPW 제어신호의 5V 전압레벨을 12V로 승압하여 상기 4개의 SPW 모터구동모듈(20)로 인가시키는 전압 레귤레이터 역할을 한다.The LIN interface 40 boosts the 5V voltage level of the serial SPW control signal output from the master module 30 to 12V and serves as a voltage regulator for applying the four SPW motor driving modules 20.
