Description
본 발명은 자동차의 엑추에이터(actuator)구동회로에 있어서 유지출력을 위하여 구비되는 시멘트(CIMENT) 저항에 의한 과부하로 인하여 발생하던 기판의 과열 현상을 방지하기 위한 자동차의 엑추에이터 구동 회로에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an actuator driving circuit of a vehicle for preventing overheating of a substrate caused by an overload caused by a cement resistance provided for holding output in an actuator driving circuit of a vehicle.
자동차에는 각종 기계 등을 작동시키는 모터(motor), 유압 실린더( cylinder), 솔레노이드(solenoid) 등의 장치를 구동하는 엑추에이터가 장착되어 있다.Automobiles are equipped with actuators for driving devices such as motors, hydraulic cylinders, solenoids, and the like that operate various machines.
종래의 엑추에이터 구동 장치는 도1과 같이 이루어지며 그 동작 관계는 다음과 같다.Conventional actuator drive device is made as shown in Figure 1 and the operation relationship is as follows.
먼저 마이컴(1)에서 초기 구동을 위한 포스(force)신호(S1)와 유지 신호를 위한 듀티(duty)신호(S2)를 출력한다.First, the microcomputer 1 outputs a force signal S1 for initial driving and a duty signal S2 for a sustain signal.
상기 포스 신호(S1)에 의해 트랜지스터(T1, T2)는 턴온되어 전원(Vb)이 엑추에이터(2)로 인가된다.The transistors T1 and T2 are turned on by the force signal S1 so that the power supply Vb is applied to the actuator 2.
그리고 엑추에이터(2)의 온을 유지하기 위한 듀티 신호(S2)에 의해 트랜지스터(T3, T4)가 턴온되고 시멘트 저항(R7)에 의해 전원(Vb)이 전압 강하되어 엑추에이터(2)로 인가된다.The transistors T3 and T4 are turned on by the duty signal S2 for keeping the actuator 2 on, and the power supply Vb is dropped by the cement resistor R7 and applied to the actuator 2.
따라서 포스 신호(S1)에 의해 엑추에이터(2)의 초기 구동이 이루어지고 듀티 신호(S2)에 의해 소정 시간 동안 전류가 흘러 엑추에이터(2)의 동작이 이루어진다.Accordingly, the initial driving of the actuator 2 is performed by the force signal S1, and the current flows for a predetermined time by the duty signal S2 to operate the actuator 2.
그런데 종래의 엑추에이터 구동 방식은 듀티 출력을 위해 장착된 시멘트 저항의 과부하로 인하여 기판 자체가 과열되는 현상이 발생하므로 엑추에이터의 동작이 안정되게 이루어지지 않을 뿐만 아니라 제품의 크기가 불필요하게 크고 외관상 좋지 못하다.However, in the conventional actuator driving method, the substrate itself is overheated due to the overload of the cement resistor mounted for the duty output, so that the actuator is not operated stably and the size of the product is unnecessarily large and does not look good.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 마이컴으로부터 출력되는 신호를 쵸핑(chopping)방식으로 변환하여 시멘트 저항을 삭제 하고 논리 게이트를 이용하여 간단하게 처리하도록 하여 기판의 과열을 방지하고 원가를 절감하는데 그 목적이 있다.The present invention has been made to solve the above problems, by converting the signal output from the microcomputer to the chopping method to remove the cement resistor and to simply process using a logic gate to prevent overheating of the substrate The purpose is to reduce costs.
상기한 목적을 달성하기 위한 수단으로서, 포스 신호 및 듀티 신호와 펄스를 출력하는 마이컴과; 상기 마이컴으로부터 출력된 포스 신호와 펄스를 논리합하는 포스 신호 처리부와; 상기포스 신호 처리부의 출력과 마이컴에서 출력된 듀티 신호를 논리곱하는 구동 제어부와; 상기 구동 제어부의 신호에 따라 소정의 전류를 인가하는 구동부와; 상기 구동부에서 전달된 전류를 인가받아 여자되는 엑추에이터로 이루어지는 것을 특징으로 한다.As a means for achieving the above object, a microcomputer for outputting a force signal, a duty signal and a pulse; A force signal processing unit for ORing the force signal and the pulse output from the microcomputer; A driving controller for performing an AND operation on the output of the force signal processor and the duty signal output from the microcomputer; A driver which applies a predetermined current according to a signal of the drive controller; Characterized in that it consists of an actuator that is applied to receive the current transmitted from the drive unit.

이하, 첨부된 도면을 참조로하여 본 발명의 가장 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명의 구성을 도2를 참고로 하여 설명하면 다음과 같다.The configuration of the present invention will be described with reference to FIG.
포스신호(S1)와 듀티 신호(S2)와 일정 간격의 펄스(pulse; S3)를 출력하는 마이컴(1)과, 상기 마이컴(1)의 포스 신호(S1)와 펄스(S3)를 논리합하는 OR게이트(G1)와, 상기 OR게이트(G1)의 출력단자에 일측단자가 연결되는 저항(R10)과, 상기 저항(R10)의 타측단자를 입력으로 하고 마이컴(1)의 듀티 신호(S2)를 입력하는 AND게이트(G2)와, 상기 AND게이트(G2)의 출력단자에 일측단자가 연결되는 저항(R20)과, 상기 저항(R20)의 타측단자에 베이스가 연결되고 에미터가 접지되어 있는 트랜지스터(T1)과, 상기 트랜지스터(T1)의 컬렉터에 일측단자가 연결되는 저항(R30)과, 상기 저항(R30)의 타측단자에 베이스가 연결되고 컬렉터에 전원(Vb)에 연결되며 에미터에 엑추에이터(2)가 연결되어 있는 트랜지스터(T2)로 이루어진다.OR for ORing the force signal S1 and the duty signal S2 and the microcomputer 1 for outputting a pulse S3 at a predetermined interval, and the force signal S1 and the pulse S3 of the microcomputer 1. The duty signal S2 of the microcomputer 1 is inputted with the gate G1, the resistor R10 having one terminal connected to the output terminal of the OR gate G1, and the other terminal of the resistor R10 being input. An AND gate (G2) to input, a resistor (R20) having one terminal connected to an output terminal of the AND gate (G2), and a transistor having a base connected to the other terminal of the resistor (R20) and an emitter grounded. T1, a resistor R30 having one terminal connected to the collector of the transistor T1, a base connected to the other terminal of the resistor R30, a power source Vb connected to the collector, and an actuator to the emitter. It consists of the transistor T2 to which (2) is connected.
상기와 같이 이루어지는 본 발명의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention made as described above are as follows.
마이컴(1)에서 출력된 포스 신호(S1)와 펄스 신호(S3)를 논리합하여 출력되는 신호는 AND게이트(G2)에서 듀티 신호(S2)와 논리곱되어 최종적으로 구동부로 인가된다.The signal output by ORing the force signal S1 and the pulse signal S3 output from the microcomputer 1 is logically multiplied with the duty signal S2 at the AND gate G2 and finally applied to the driver.
이때 구동부로 인가되는 신호는 도2에 도시된 엑추에이터(2)의 신호와 동일하며 이 구동부로 인가된 신호에 따라 각 트랜지스터(T1, T2)는 턴온/턴오프된다.In this case, the signal applied to the driver is the same as the signal of the actuator 2 shown in FIG. 2 and the transistors T1 and T2 are turned on / off according to the signal applied to the driver.
따라서 트랜지스터(T1, T2)의 턴온/턴오프에 따라 엑추에이터(2)로 인가되는 전원(Vb)의 공급/차단이 이루어지고 이에 따라 엑추에이터(2)의 동작이 이루어진다.Therefore, according to the turn-on / turn-off of the transistors T1 and T2, the supply / blocking of the power supply Vb applied to the actuator 2 is performed and thus the operation of the actuator 2 is performed.
본 발명은 시멘트 저항이 삭제되었으므로 기판의 과열이 발생되지 않으며 이로 인하여 엑추에이터의 동작에 정확성을 기하며 종래에 비해 회로의 사이즈를 상당량 작게 할 수 있고 원가 절감 효과도 기대할 수 있다.In the present invention, since the cement resistance is eliminated, overheating of the substrate does not occur, thereby providing accuracy in the operation of the actuator, and significantly reducing the size of the circuit and reducing the cost as compared with the related art.
