The electronic vehicle has electronic control in various fields such as an engine control unit (ECU), an electronically controlled carburetor (FBC), and an electronically controlled fuel injection unit (ECI).
이러한 각종 전자 제어 장치들은 차량에 각종 센서들을 장착하고 이들 센서로부터 센싱된 신호를 받아 적절한 연산을 통해 출력 신호를 제공하여 각종 기계장치들을 제어하고 있다. 이때, 제어기와 센서 또는 각종 장치들 사이에는 일방향 또는 쌍방향으로 통신이 가능하도록 이루어져야 하는데, 일반적으로 RS-232-C 시리얼 통신 방식이 많이 채용되어 왔다.These various electronic control devices are equipped with various sensors in the vehicle, and receives the signals sensed from these sensors to provide output signals through appropriate calculations to control various mechanical devices. At this time, the controller and the sensor or various devices should be made to enable communication in one or two directions, generally RS-232-C serial communication has been adopted a lot.
하지만, 상기 RS-232-C 시리얼 통신 방식은 통신 속도가 느린 직렬 통신 방식이기 때문에 빠른 시간내에 많은 값의 신호를 처리하기가 어려울 뿐만 아니라 제어 신호를 출력하는데에도 많은 시간이 필요하게 되었다.However, since the RS-232-C serial communication method is a serial communication method having a slow communication speed, not only it is difficult to process a large number of signals in a short time but also a lot of time is required to output a control signal.
이에 최근 들어서는 각종 전자 제어 장치에 처리 속도가 빠른 캔(CAN) 통신 방식이 많이 채용되어 실용화되어 있다.In recent years, a large number of CAN communication systems having high processing speeds have been adopted for various electronic control devices.
본 발명은 처리 속도가 빠른 캔(CAN) 통신 방식을 사용하는 전자 제어 장치로부터 연료 소모량과 주행 거리를 통해 실시간으로 연비를 디스플레이시켜 주는 ＣＡＮ 메시지를 이용한 연비 표시 장치를 제공하는데 그 목적이 있다.An object of the present invention is to provide a fuel economy display using a CAN message that displays fuel consumption in real time through fuel consumption and driving distance from an electronic control device using a CAN communication method having a high processing speed.

이를 실현하기 위한 본 발명은 캔(CAN) 통신 방식을 채용하는 전자 제어 장치에 있어서, 상기 전자 제어 장치로부터 연료 소비량과 주행 거리를 일정 시간 단위로 입력받아 연비를 계산하는 제어기와, 제어기로부터 계산된 연비를 실시간으로 디스플레이시켜 주는 표시기로 이루어진 것을 특징으로 한다.According to an aspect of the present invention, there is provided an electronic control apparatus employing a CAN communication method, comprising: a controller configured to calculate fuel economy by receiving fuel consumption and driving distance from the electronic controller in a predetermined unit of time; It is characterized by consisting of an indicator that displays the fuel economy in real time.
본 발명의 바람직한 구현예에서, 상기 제어기는 다음과 같이 연비를 계산하는 것을 특징으로 한다.In a preferred embodiment of the invention, the controller is characterized in calculating fuel economy as follows.
이하, 첨부도면을 참조하여 본 발명의 구성 및 작용 효과에 대해 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the configuration and effect of the present invention will be described.
첨부도면 도 1은 본 발명에 따르는 연비 표시 장치를 나타내는 구성도를 나타낸다. 여기서, 도면부호 100은 종래의 캔 통신 방식을 채용하는 전자 제어 장치를 나타낸다.1 is a block diagram illustrating a fuel efficiency display device according to the present invention. Here, reference numeral 100 denotes an electronic control apparatus employing a conventional can communication method.
본 발명은 상기 전자 제어 장치(100)로부터 일정 시간, 예를 들면 5분 내지 10분 간격으로 연료 소비량과 주행 거리를 검출하고, 이들 검출된 값을 통해 연비를 구하게 된다. 이를 실현하기 위해 상기 전자 제어 장치(100)로부터 필요한 값을 입력받는 제어기(10)와 계산된 연비를 실시간으로 디스플레이시켜 주는 표시기(20)를 포함하게 된다.The present invention detects fuel consumption and travel distance at a predetermined time, for example, 5 minutes to 10 minutes, from the electronic control apparatus 100, and calculates fuel economy through these detected values. In order to realize this, it includes a controller 10 that receives the necessary value from the electronic control device 100 and an indicator 20 for displaying the calculated fuel efficiency in real time.
여기서, 상기 전자 제어 장치(100)는, 첨부도면에서 도시한 바와 같이, 엔진 제어 장치(ECU), ABS ECU, 차체 제어기 등을 포함하게 되며, 이들 각 장치들은 캔 버스(can bus)(30)에 연결되어 있으며, 상기 캔 버스(30)는 이들 각 장치로부터 신호가 출력됨에 따라 이를 검출하여 상기 제어기(10)에 입력시켜 주게 된다.Here, the electronic control device 100, as shown in the accompanying drawings, will include an engine control unit (ECU), ABS ECU, body controller, etc., each of these devices can bus (can bus) (30) The bus bus 30 detects the signal from each of these devices and inputs it to the controller 10.
특히, 본 발명에서는 상기 전자 제어 장치(100), 그 중에서 차량의 연료 소비량과 주행 거리를 나타내는 장치인 경우 검출값이 일정 시간(예를 들면, 5분 또는 10분) 간격으로 항상 출력시켜 주도록 구성하게 된다.Particularly, in the present invention, in the case of the electronic control device 100, among which the fuel consumption amount and the driving distance of the vehicle are shown, the detection value is always output at a predetermined time (for example, 5 minutes or 10 minutes). Done.
이러한 값은 상기 제어기(10)를 통해 다음과 같이 연비가 계산되어 그 결과가 상기 표시기(20)에 표시되게 된다.This value is calculated by the controller 10 as follows, the fuel economy is calculated and the result is displayed on the indicator 20.
여기서, FC는 단위 시간당 연비를, Dc는 현재 검출된 주행 거리를, Dp는 Dc 바로 전에 검출된 주행 거리를, Fc는 현재 검출된 연료 소비량을, Fp는 Fc 바로 직전에 검출된 주행 거리를 각각 나타낸다.Where FC is the fuel economy per unit time, Dc is the currently detected driving distance, Dp is the driving distance detected just before Dc, Fc is the fuel consumption currently detected, and Fp is the driving distance detected immediately before Fc, respectively. Indicates.
본 발명의 바람직한 구현예에서, 상기 연료 소비량은 인젝터(미도시됨)를 통해 실린더에 분사된 누적 연료량을 검출함으로써, 실제 주행에 필요한 연료량을 얻을 수 있게 되어 소비 연료량의 오차를 줄일 수 있게 하는 것이 바람직하다.In a preferred embodiment of the present invention, the fuel consumption is to detect the cumulative fuel amount injected into the cylinder through the injector (not shown), it is possible to obtain the amount of fuel required for the actual running to reduce the error of the amount of fuel consumption desirable.
따라서, 상기 제어기(10)는 현재까지의 주행 거리와 소비 연료량만을 검출하던 종래의 방법과 달리 일정 시간 간격을 두고 이들 값을 빼서 거리를 연료 소비량으로 나눔에 따라 현재의 연비를 알 수 있게 된다.Therefore, unlike the conventional method of detecting only the distance traveled and the amount of fuel consumed up to now, the controller 10 can know the current fuel economy by subtracting these values at regular time intervals and dividing the distance by the fuel consumption.
이상에서 본 바와 같이 본 발명은 종래의 캔 통신 방식을 채용하는 차량에 있어서 일정 시간 동안의 연료 소비량과 주행 거리를 통해 연비를 계산할 수 있게 함으로써 다음과 같은 효과를 얻게 된다.As described above, the present invention provides the following effects by allowing the fuel economy to be calculated based on fuel consumption and driving distance for a predetermined time in a vehicle employing the conventional can communication method.
1) 종래의 차량에서 현재까지의 연료 소비량과 주행 거리만을 확인하던 종래의 장치와는 달리 현재의 연비를 쉽게 알 수 있게 된다.1) Unlike conventional devices that only check fuel consumption and driving distance to date in a conventional vehicle, it is easy to know the current fuel economy.
2) 인젝터 등을 통해 실린더에 공급된 연료량을 통해 연료 소모량을 검출하기 때문에 오차가 거의 없이 정확하다.2) Since the fuel consumption is detected by the amount of fuel supplied to the cylinder through an injector, it is accurate with almost no error.
