Description

차량 자세에 따른 전자제어 에어컨{cars position in accordingly with electronic control air conditioner}Car position in accordance with with electronic control air conditioner}

자동차의 에어컨을 자동 조절하는 장치로 종래의 에어컨은 설정온도에 따라 온도를 조절하기 위해 온도센서에 검출된 수치가 설정된 온도의 수치보다 높거나 낮을 때 자동으로 동작하거나 정지시키는 기능을 가지고 있었고 수동의 경우 일정간격(시간)에 따라 동작과 차단을 반복하도록 되어있었다. 또한 실린더에 볼을 넣어만든 경사센서를 적용한 게 있는데 차량이 경사진 곳에 정차하거나 주차를 하고있을 때 에어컨이 작동이 안돼는 문제점과 소정치 이상의 엔진회전시 차단하게되어있는 바 고속주행시 에어컨을 차단 해버려 고속주행시에어컨을 사용할 수 없는 문제점과 엑셀레이터센서를 별도를 장착해야하는 부담을 안고 있었다.It is a device that automatically adjusts the air conditioner of a vehicle. The conventional air conditioner has a function of automatically operating or stopping when the value detected by the temperature sensor is higher or lower than the set temperature to adjust the temperature according to the set temperature. In this case, the operation and the blocking were repeated at a certain interval (time). In addition, there is an inclination sensor made by inserting a ball into the cylinder.The problem is that the air conditioner does not work when the vehicle is stopped or parked on the slope, and the engine is blocked when the engine is rotated above a certain level. There was a problem of not being able to use the air conditioner at high speed driving and the burden of attaching the accelerator sensor separately.

본 발명은 상기의 문제점을 해결 한 것으로 에어컨을 작동시키고 경사진 언덕길을 주행할 때 에어컨의 부하에 따른 출력의 손실과 에너지 낭비를 줄이기 위해 에어컨을 작동시켰을 지라도 경사센서에 의해 일정 경사각에 이르면 정상범위로 복귀할 때까지 자동으로 에어컨의 작동을 차단시키고 차속센서, 제동등 스위치, TPS, 킥다운 신호를 이용하여 에어컨을 제어하며 본 발명의 기능을 사용자가 선택하여 사용할 수 있도록 하고 에어컨을 켜고 주행시 신속한 가속을 가능케하며 출력저하를 방지하고 환경과 자원의 효율적 사용을 제공하는 것이다.The present invention solves the above problems, even when operating the air conditioner and driving the air conditioner to reduce the loss of output and energy waste due to the load of the air conditioner when driving on a sloped hill road when the inclination sensor reaches a certain inclination angle normal range It automatically shuts off the air conditioner until it returns to the vehicle and controls the air conditioner using the vehicle speed sensor, brake light switch, TPS, kickdown signal, and enables the user to select and use the functions of the present invention. To reduce output and to provide efficient use of the environment and resources.

자동차에어컨을 구성하는 차 실내외의 주위온도를 검출하는 각 센서(실내센서, 덕트센서, 외기센서)외에 추가로 경사센서, 스로틀포지션센서, 차속센서, 제동등 스위치, ECAT(자동변속기) 컨트롤유닛을 장착, 연결하여 검출된 신호와 컨트롤 패널의 조작신호 및 포텐쇼 미터의 위치 검출 신호를 컨트롤 유닛에 연산 비교 증폭하여 에어믹스 도어 개도 변화, 팬의 변속, 컴프레서 ON, OFF를 자동 제어한다. 경사진 언덕길을 주행하거나 급가속할 때 이렇게 해서 신호가 검출되거나 설정범위를 초과하게 될 경우 에어컨의 작동이 제어된다. 이 기능을 운전자의 선택에 따라 작동시키고 시키지 않게 끔 하기 위하여 별도의 선택스위치를 구성하게 된다. 이 기능을 수행하기 위해 에어컨컨트롤 유닛에 작동스위치를 직접적으로 연결하여 작동을 제어하는 방법이 있으며 또한 간접적으로 전자제어장치에 릴레이를 통하여 경사센서에서 검출된 신호가 설정치를 초과하거나 신호가 검출되면 릴레이를 작동하여 에어컨스위치를 차단하게된다. 자동차가 정상 주행 경사각으로 복귀하게되면 에어컨의 작동도 복귀가 된다. 컨트롤 유닛에 연결된 차속센서의 검출치를 통해 주행 시에만 본 기능을 작동시킬 수 있게 한다. 경사로에 정차하거나 주차하여 에어컨을 가동시킬 경우 경사센서에 의한 차단을 방지하기 위한 것이다. 제동등 스위치는 정지시 경사센서에 의한 에어컨작동차단을 막는다. 주행중 차량을 정지시킬 때 언덕길일 지라도 에어컨이 작동할 수 있도록 하여 엔진브레이크효과로 제동력을 증강 시킬 수 있다. 에어컨기능만을 차단할 수있게 할 수 있기 때문에 송풍은 계속되므로 짧은 구간의 경사 길을 주행할 때는 경사길 주행 전에 에어컨이 냉각되어있으므로 유입되는 공기는 식혀서 송풍이 되므로 긴 구간을 주행하지 않는 한 쉽게 덥혀지지 않는다. 급가속할 때에도 차량의 중심이 뒤로 쏠리기 때문에 본 기능의 득을 볼 수있으며 운전자가 원하는 경사각을 설정할 경우 경사센서만으로도 급가속이나 급출발시 차량이 중심이 관성의 법칙에 의해 뒤로 이동하여 에어컨 작동을 차단할 수 있게된다. 오토매틱차량은 가속패달을 깊게 밟아 급가속할 때 일어나는 킥다운 신호를 컨트롤 유닛에 입력 급가속시 에어컨작동에 의한 출력손실 없애고 순간 가속을 할 수 있게한다. 상기 한 구성과 작동을 첨부도면에 의거 간략하게 설명하면 다음과 같다. 도 1은 본 발명의 주요구성만을 간략하게 나타낸 것으로 제동등스위치, 경사센서, 자동변속기의 컨트롤 유닛에서 보내는 킥다운 신호와 차속센서 그리고 버튼입력부인 컨트롤패널에서 입력되는신호를 에어컨컨트롤유닛에서 연산 출력하여 에어컨을 작동제어하고 디스플레이에 표시를 한다. 도 3은 자동변속기 전자제어장치에서 이미 중복되는 센서를 에어컨 컨트롤 유닛과 공유를 함으로써 에어컨을 제어할 수 있는 시스템도 이며 도 4는 다른 기존의 에어컨장치와 함께 오토 컨트롤 되는 전체적인 구조를 블럭다이어그램으로 표현하여 나타내었으며 경사모드스위치를 작동시키면 버튼에 선택램프에 불이켜지며 디스플레이에 경사각이 표시가 되게 나타내고 있다. 도 7은 경사센서와 차속센서가 ECU 에 연결되어 에어컨스위치의 회로가 릴레이를 통해 단속 되도록 되어있는 것을 나타낸다.In addition to each sensor (indoor sensor, duct sensor, and outside air sensor) that detects the ambient temperature inside and outside the car constituting the air conditioner, a tilt sensor, throttle position sensor, vehicle speed sensor, brake light switch, and ECAT (automatic transmission) control unit are installed. By connecting and amplifying the detected signal, the operation signal of the control panel and the position detection signal of the potentiometer to the control unit, it automatically controls the change of opening degree of the airmix door, shifting of the fan, and compressor on / off. When driving or steeping downhill slopes, if the signal is detected or the set range is exceeded, the operation of the air conditioner is controlled. A separate selector switch is configured to disable or disable this function at the operator's option. In order to perform this function, there is a method of controlling the operation by directly connecting the operation switch to the air conditioner control unit. Also, if the signal detected by the inclination sensor exceeds the set value or a signal is detected indirectly through the relay to the electronic controller, the relay To operate the air conditioner switch. When the vehicle returns to the normal driving inclination angle, the operation of the air conditioner also returns. The detection of the vehicle speed sensor connected to the control unit makes it possible to activate this function only when driving. It is to prevent the blocking by the tilt sensor when the air conditioner is operated by stopping or parking on the slope. The brake light switch prevents the air conditioner from shutting off by the tilt sensor when it stops. When stopping the vehicle while driving, even if it is a hill, the air conditioner can be operated to increase the braking force by the engine brake effect. Since the air-conditioning function can be cut off, the airflow continues, so when driving on slopes of short sections, the air conditioner is cooled before driving on slopes, and the incoming air cools and blows, so it does not warm up easily unless you travel on long sections. . Because the center of the vehicle is tilted backwards even during rapid acceleration, you can benefit from this function.If you set the angle of inclination desired by the driver, the center of the vehicle will move backwards due to the law of inertia when the acceleration or sudden departure is made only by the tilt sensor. You can block. The automatic vehicle is able to accelerate rapidly by stepping down on the acceleration pedal and eliminating the output loss caused by the air conditioner operation during the rapid acceleration of the kickdown signal generated when the acceleration is accelerated. The above configuration and operation will be described briefly based on the accompanying drawings. 1 is a simplified view showing only the main configuration of the present invention by calculating the output signal from the control panel of the brake light switch, the tilt sensor, the automatic transmission and the kick-down signal and the vehicle speed sensor and the button input unit in the air conditioning control unit Operate and control the air conditioner and mark it on the display. FIG. 3 is a system diagram of controlling an air conditioner by sharing an overlapping sensor with an air conditioner control unit in the electronic transmission electronic control device. FIG. 4 is a block diagram showing the overall structure of the auto control with another existing air conditioner device. When the inclination mode switch is operated, the select lamp lights on the button and the inclination angle is displayed on the display. 7 shows that the inclination sensor and the vehicle speed sensor are connected to the ECU so that the circuit of the air conditioner switch is intermittent through the relay.

본 발명은 에어컨을 작동시키고 경사진 언덕길을 주행하거나 급가속할 때 에어컨의 부하에 따른 출력의 손실과 에너지낭비를 줄여주게 되므로 힘있는 가속을 가능케 해주며 주정차시의 오작동을 방지해주며 엔진부하에 따른 매연의 배출로 인한 환경오염을 줄일 수 있게되며 제동시에는 에어컨작동시의 엔진부하를 이용하여 제동능력의향상을 이용할 수 있게하는등 에너지의 낭비를 줄일 수 있다.The present invention reduces the power loss and energy consumption according to the load of the air conditioner when operating the air conditioner and driving down a steep hill road or accelerates, thus enabling a powerful acceleration and preventing malfunctions during parking and engine load. It is possible to reduce the environmental pollution caused by the emission of soot, and to reduce the waste of energy by making use of the improvement of the braking capacity by using the engine load when the air conditioner is operating during braking.
