이에 따르면, 보조히터(3)를 포함하여 자동차내의 각종 전장품들에 대한 전반적인 제어를 실시하는 엔진 전자제어 유니트(1)와; 상기 엔진 전자제어 유니트(1)에서 출력되는 온/오프신호에 부응하여 작동되어 보조히터(3)들에 공급되는 전력을 제어하는 수개의 릴레이(2)와; 실내공기 흡기부에 설치된 상태에서 상기한 수개의 릴레이(2)를 통해 전원전압이 공급되면 실내로 흡입되는 공기를 직접적으로 가열시켜 주는 수개의 보조히터(3)로 구성된 디젤 자동차내의 보조히터 제어장치에 있어서,According to this, the engine electronic control unit 1 including the auxiliary heater 3 to perform overall control of the various electrical equipment in the vehicle; Several relays (2) operated in response to the on / off signal output from the engine electronic control unit (1) to control power supplied to the auxiliary heaters (3); Auxiliary heater control device in a diesel vehicle comprising a plurality of auxiliary heaters (3) for directly heating the air sucked into the room when the power supply voltage is supplied through the above several relay (2) in the indoor air intake unit To

입력단은 상기 엔진 전자제어 유니트(1)의 보조히터 온/오프신호 출력단에 연결되고 수개의 출력단은 상기 릴레이(2)들의 코일 일단부에 각각 연결된 상태에서 상기 엔진 전자제어 유니트(1)의 제어를 받아 보조히터 구동용 릴레이(2)들을정해진 시간차를 두고 차츰 많이 구동시키는 형태를 갖고 순차적으로 작동시켜 주는 히터 제어부(4)를 부가 설치한 것을 특징으로 한다.An input terminal is connected to an auxiliary heater on / off signal output terminal of the engine electronic control unit 1 and several output terminals are connected to one end of a coil of the relays 2 to control the engine electronic control unit 1. It is characterized in that the auxiliary heater driving relay (2) has a form to drive a plurality of gradually over a predetermined time difference and the heater control unit (4) to operate sequentially.

이때, 상기 히터 제어부(4)는 별도의 부품을 가지고 구성하지 않고 엔진 전자제어 유니트(1)내의 로직의 일부를 변경하여 사용하여도 된다.At this time, the heater control unit 4 may be used by changing a part of the logic in the engine electronic control unit 1 without having a separate component.

또한, 상기 보조히터(3)들은 대략 0.3kW의 소비전력을 갖는 것으로, 그 구동 시간차는 대략 15초 정도의 사이를 두고 실시하도록 하였다.In addition, the auxiliary heaters (3) has a power consumption of about 0.3kW, the driving time difference is to be carried out between about 15 seconds.

이와같이 구성된 본 발명 장치의 작용효과를 설명하면 다음과 같다.Referring to the operation and effect of the device of the present invention configured as described above are as follows.

먼저, 본 발명 장치는 공지된 디젤 자동차내의 보조히터 제어장치에 히터 제어부(4)를 부가 설치하여 엔진 전자제어 유니트(1)로 부터 보조히터 온신호가 출력되면 상기 히터 제어부(4)에서 보조히터 구동용 릴레이(2)들을 정해진 시간차를 두고 차츰 많이 구동시키는 형태를 갖도록 순차적으로 작동시켜 능동적인 전압 제어가 가능하게 한 것이다.First, the apparatus of the present invention additionally installs the heater control unit 4 in the auxiliary heater control device in a known diesel vehicle, and when the auxiliary heater on signal is output from the engine electronic control unit 1, the auxiliary heater is heated by the heater control unit 4. The driving relays 2 are sequentially operated to have a form of gradually driving a plurality of driving relays 2 at a predetermined time difference, thereby enabling active voltage control.

즉, 상기 엔진 전자제어 유니트(1)로부터 히터 "온"신호가 출력되면 히터 제어부(4)에서는 도 4와 같이 최초 일정시간(예를들어 15초) 동안에는 보조히터 구동용 릴레이(2)들 중 하나만 "온"시켜 수개의 보조 히터(3)중 그와 연결된 하나의 보조히터만 구동되도록 하고, 또 일정시간이 경과되면 이번에는 보조히터 구동용 릴레이(2)들 중 두개의 릴레이를 "온"시켜 수개의 보조 히터(3)중 그들과 연결된 두개의 보조히터가 구동되도록 하며, 또한 상기와 같은 상태에서 다시 일정시간이 경과되면 이번에는 보조히터 구동용 릴레이(2)들 모두를 "온"시켜 수개의 보조 히터(3)가 모두 구동되도록 한다.That is, when the heater "on" signal is output from the engine electronic control unit 1, the heater controller 4 of the auxiliary heater driving relays 2 for the first predetermined time (for example, 15 seconds) as shown in FIG. Only one "on" of the several auxiliary heaters (3) is driven so that only one auxiliary heater connected to it, and after a certain time has elapsed this time, two of the auxiliary heater driving relays (2) "on" Of the auxiliary heaters 3 to drive the two auxiliary heaters connected to them. Also, when a predetermined time elapses in the above state, all of the auxiliary heater driving relays 2 are turned on. Several auxiliary heaters 3 are all driven.

따라서, 자동차의 밧데리 전력이 소정시간 간격으로 예를들어 약 0.3kW씩 다단(예를들어 3단)으로 변화되므로 차량의 전기 쇼크가 줄어들어 운전자나 승객 등이 헤드 램드 등의 조도 변화를 인식할 수 없게 된다.Therefore, the battery power of the vehicle is changed to multi-stage (for example, three-stage) by about 0.3kW at predetermined time intervals, so the electric shock of the vehicle is reduced, so that the driver or passenger can recognize the change in illuminance such as the head lamp. There will be no.

뿐만 아니라, 보조히터(3)의 작동 초기에는 약 0.3kW의 전력만 사용하므로 엔진글로우 플러그 작동중에도 보조히터들을 작동시킬 수 있다.In addition, since the auxiliary heater 3 uses only about 0.3 kW of power at the beginning of operation, the auxiliary heaters can be operated even during the operation of the engine glow plug.

이상에서 설명한 바와 같이 본 발명에 의하면, 직분사 디젤엔진이 장착된 자동차의 실내 초기 난방성능을 증진시키기 위해 설치된 보조히터들을 구동시킬시 초기에는 하나만 구동하다가 일정시간이 경과되면 두개, 또 그로부터 일정시간이 경과되면 3개씩 구동시키는 방식을 체택하므로써, 난방성능은 저해하지 않는 가운데 차량내 전력 사용량이 급격히 변화되는 것을 방지할 수 있어 보조히터의 구동시 헤드 램프 등의 조도가 급격히 변화되는 등의 문제점을 해결할 수 있는 것이다.As described above, according to the present invention, when driving auxiliary heaters installed in order to improve the initial heating performance of an indoor vehicle equipped with a direct injection diesel engine, only one is initially driven, and then, after a certain time, two, and a predetermined time therefrom. After the elapse of time, by adopting a method of driving three by one, it is possible to prevent the power consumption in the vehicle from being changed suddenly without impairing the heating performance. It can be solved.
