Description

주행가능거리 연산용 연비의 표시장치{FUEL RATIO DISPLAY APPARATUS FOR RUNNING RANGE MEASURING}FUEL RATIO DISPLAY APPARATUS FOR RUNNING RANGE MEASURING}

본 발명은 주행가능거리 연산용 연비의 표시장치에 관한 것으로, 보다 상세하게 일정 거리 주행시 또는 일정 연료량의 소모시마다 기준 연비를 갱신함으로써 실연비를 추종할 수 있게 하며, 연비의 증감 속도를 가변되게 하여 신뢰도를 높이도록 하고, 급유없이 주행가능 거리가 증가하는 것을 최소화할 수 있게 한 주행가능거리 연산용 연비의 표시장치에 관한 것이다.The present invention relates to a display device for calculating the fuel consumption for driving distance, and more specifically, it is possible to follow the actual fuel consumption by updating the standard fuel consumption at a certain distance driving or when a certain amount of fuel is consumed. The present invention relates to a display device for fuel efficiency for driving distance calculation that enables to increase reliability and minimizes the increase in the driving distance without refueling.

주지된 바와 같이, 일반적으로 자동차의 클러스터에는 속도와 주행거리가 표시되며, 최근에는 연료 잔량으로 주행할 수 있는 거리를 산출하여 클러스터에 주행가능거리(Distance To Empty; DTE)를 표시하는 기술이 개시되어 있다.As is well known, in general, a cluster of vehicles displays speed and mileage, and recently, a technology for displaying distance to empty (DTE) in a cluster by calculating a distance that can be driven by the remaining fuel amount is disclosed. It is.

종래 기술에 따른 주행가능거리 표시 방법은, 연료 탱크에 남아있는 연료의 잔량을 검출하고, 검출된 연료 잔량에 고정연비를 곱하여 주행가능거리를 산출하는 방법이 사용되었다.In the prior art, the driving distance display method is a method of detecting the residual amount of fuel remaining in the fuel tank, and calculating the driving distance by multiplying the detected fuel residual amount by a fixed fuel consumption.

즉, 주행가능거리(㎞)=연료잔량(Liter)× 연비(㎞/Liter)의 계산식을 사용한다. 따라서, 주행가능거리를 정확하게 연산해내기 위해서는 최대한 실연비의 추종이 필요하다고 하겠다.In other words, a calculation formula of the driving distance (km) = fuel remaining amount (Liter) x fuel consumption (km / Liter) is used. Therefore, it is necessary to follow the actual fuel ratio as much as possible to accurately calculate the driving distance.

그러나, 연비는 운전자의 운전습관, 도로의 상태 등 주행조건의 변화에 따라 함께 변화하게 되고 따라서, 상기 주행조건의 변화를 고려하지 않고 설정된 고정연비를 기초로 주행가능거리를 산출하는 경우에는 실제 주행가능거리와 표시되는 주행가능거리에 큰 차이가 발생하여 운전자에게 혼동을 주었다.However, the fuel economy changes according to the change of the driving conditions such as the driving habits of the driver, the state of the road, etc. Therefore, the actual driving is calculated in the case of calculating the travelable distance based on the fixed fixed fuel economy without considering the change of the driving conditions. There was a big difference between the possible distance and the displayed range, which confuses the driver.

따라서, 주행조건의 변화를 반영하기 위하여, 설정된 시간 간격으로 산출되는 변동연비를 기초로 주행가능거리를 산출하여 표시하는 방법이 현재 사용되고 있다.Therefore, in order to reflect the change in the driving conditions, a method of calculating and displaying the driving possible distance based on the variable fuel efficiency calculated at set time intervals is currently used.

그러나, 상기 변동연비만을 기초로 주행가능거리를 산출하여 표시하는 경우에는 변동연비의 특성상 주행조건이 갑자기 변화하는 경우, 주행가능거리가 급격하게 변화하게 된다.However, when the driving range is calculated and displayed based only on the variable fuel economy, when the driving condition suddenly changes due to the characteristics of the variable fuel economy, the driving range changes abruptly.

이는 변동연비를 기초로 주행가능거리를 산출하기 때문에 발생하는 현상으로 주행가능거리가 급격하게 감소하거나 주행가능거리가 오히려 증가하는 현상이 발생하고, 이러한 현상은 운전자에게 혼동을 유발하는 동시에 주행가능거리 표시장치에 대한 신뢰성을 악화시키게 된다.This phenomenon occurs because the driving distance is calculated based on the variable fuel economy, and the driving distance sharply decreases or the driving distance increases, which causes confusion for the driver and at the same time, the driving distance. The reliability of the display device is deteriorated.

본 발명은 상기한 종래 기술의 사정을 감안하여 이루어진 것으로, 일정 거리 주행시 또는 일정 연료량의 소모시마다 기준 연비를 갱신함으로써 실연비를 추종할 수 있게 하며, 연비의 증감 속도를 가변되게 하여 신뢰도를 높이도록 하고, 급유없이 주행가능 거리가 증가하는 것을 최소화할 수 있게 한 주행가능거리 연산용 연비의 표시장치를 제공함에 그 목적이 있다. The present invention has been made in view of the above-described state of the art, and it is possible to follow the actual fuel consumption by updating the standard fuel consumption at a certain distance driving or when a certain amount of fuel is consumed, and to increase the reliability by varying the increase and decrease of fuel consumption. It is an object of the present invention to provide a display device of fuel efficiency for calculating the driving distance that can minimize the increase in the driving distance without refueling.

도 1은 본 발명의 일실시예에 따른 주행가능거리 연산용 연비의 표시장치의 구성을 도시한 블록구성도이다.1 is a block diagram showing the configuration of a display device for driving distance calculation fuel economy according to an embodiment of the present invention.

이를 참조하면, 본 발명의 일실시예에 따른 주행가능거리 연산용 연비의 표시장치(2)는 일정 거리 주행시 또는 일정 연료량의 소모시마다 기준 연비를 갱신함으로써 실연비를 추종할 수 있게 하며, 연비의 증감 속도를 가변되게 하여 신뢰도를 높이도록 하고, 급유없이 주행가능 거리가 증가하는 것을 최소화할 수 있게 한 장치이다.Referring to this, the display apparatus 2 for driving distance calculation according to an exemplary embodiment of the present invention may follow the fuel efficiency by updating the reference fuel efficiency every time the vehicle is driven for a certain distance or when the amount of fuel is consumed. The device is designed to increase the reliability by varying the speed of increase and decrease, and to minimize the increase in the driving distance without lubrication.

보다 상세하게, 본 발명의 일실시예에 따른 주행가능거리 연산용 연비의 표시장치(2)는 연료탱크(미도시)의 연료 잔량을 검출하는 연료량 검출부(4)와; 인젝터(미도시)의 분사량인 연료 소모량을 검출하는 엔진 ECU(5)와; 차량의 속도를 검출하는 차속 검출부(6)를 포함한다.More specifically, the display device 2 for calculating the mileage for running distance according to an embodiment of the present invention includes a fuel amount detection unit 4 for detecting a fuel remaining amount in a fuel tank (not shown); An engine ECU 5 for detecting a fuel consumption amount which is an injection amount of an injector (not shown); And a vehicle speed detector 6 for detecting the speed of the vehicle.

또한, 본 발명의 일실시예에 따른 주행가능거리 연산용 연비의 표시장치(2)는 상기 연료량 검출부(4), 엔진 ECU(5), 차속 검출부(6)로부터 출력되는 데이터를 기초로 변동연비를 산출하며 상기 산출된 변동연비와 설정된 고정연비를 기초로 급유 후 초기 주행가능거리를 산출하는 제어부(14) 및; 상기 제어부(14)로부터 출력되는 주행가능거리에 대한 신호를 수치로 표시하는 표시부(8)를 포함한다.In addition, the display device 2 for calculating the mileage for running distance according to an embodiment of the present invention is a variable fuel economy based on the data output from the fuel amount detector 4, the engine ECU 5, and the vehicle speed detector 6. A controller 14 for calculating an initial running distance after refueling on the basis of the calculated variable fuel economy and the set fixed fuel economy; And a display unit 8 for numerically displaying a signal for a driving distance output from the controller 14.

또, 상기 표시부(8)를 구동하는 표시구동부(10)가 구비되어져 있다.Moreover, the display drive part 10 which drives the said display part 8 is provided.

이때, 본 발명의 일실시예에 따른 주행가능거리 연산용 연비의 표시장치(2)에서 연산되는 상기 변동연비는 상기 엔진 ECU(5)로부터 인가받은 연료 소모량으로 차속검출부(6)에 의해 검출되어 누적된 누적 주행거리를 나누어 산출된다.In this case, the variable fuel efficiency calculated by the display apparatus 2 for driving distance calculation according to an embodiment of the present invention is detected by the vehicle speed detection unit 6 with the fuel consumption applied from the engine ECU 5. It is calculated by dividing the accumulated cumulative mileage.

이러한 변동연비는 실연비를 추종하기 위한 중요한 요소이지만, 반면에 다양한 운행 환경에 의해 변동되므로 온전하게 변동연비만을 적용하여 주행가능거리를 연산한다거나 하는 방식은 바람직하지 못하다.Such variable fuel economy is an important element for following the actual fuel economy, but on the other hand, since it is changed by various driving environments, it is not preferable to calculate the driving distance by applying only the variable fuel economy.

따라서, 본 발명의 일실시예에 따른 주행가능거리 연산용 연비의 표시장치(2)는 연비의 급격한 변동을 최소화하면서도 연비의 신뢰도를 높일 수 있게 다양한 변수의 적용을 고려한 것이다.Accordingly, the display apparatus 2 for driving distance calculation according to an embodiment of the present invention considers the application of various variables to increase the reliability of fuel economy while minimizing the rapid fluctuation of fuel economy.

한편, 본 발명의 일실시예에 따른 주행가능거리 연산용 연비의 표시장치(2)에 포함된 상기 제어부(14)는 변동연비 산출시마다 (고정연비+변동연비)/2의 연산을 통해 평균연비를 산출하고, 그 평균연비를 적용하여 주행가능거리를 산출하게 설정되어져 있다.On the other hand, the control unit 14 included in the display device 2 of the driving distance calculation fuel economy according to an embodiment of the present invention, the average fuel economy through the calculation of (fixed fuel economy + variable fuel economy) / 2 every time the variable fuel economy is calculated Is calculated, and the average fuel efficiency is applied to calculate the travelable distance.

또한, 상기 제어부(14)는 급유시나 재급유시에 변동연비를 산출하고, (고정연비+변동연비)/2의 연산을 통해 평균연비를 산출하며, 그 평균연비를 적용하여 주행가능거리를 산출하게 설정되어져 있다.In addition, the control unit 14 calculates the variable fuel economy at the time of refueling or re-fueling, calculates the average fuel economy through the calculation of (fixed fuel consumption + variable fuel economy) / 2, and calculates the driving distance by applying the average fuel economy It is set.

즉, 재급유시에는 연료잔량의 변동으로 차후 운행시의 연비에 변동이 발생될 수 있으므로 재급유시에는 변동연비를 재산출하고, 고정연비를 적용한 평균 연비도 재산출한다.That is, when refueling, fluctuations in the fuel economy may occur due to the change in the fuel residual amount. In the case of refueling, the fuel consumption is recalculated, and the average fuel consumption with fixed fuel consumption is also recalculated.

한편, 본 발명의 일실시예에 따른 주행가능거리 연산용 연비의 표시장치(2)에 포함된 상기 제어부(14)는 기설정 거리의 주행시나 기설정 연료량을 소모한 시점에 변동연비를 산출하게 설정되어져 있다.On the other hand, the control unit 14 included in the display device for calculating the fuel consumption for driving distance according to an embodiment of the present invention 2 is to calculate the variable fuel consumption when driving at a predetermined distance or when the predetermined amount of fuel is consumed. It is set.

또, 상기 제어부(14)는 산출한 평균연비가 이전 평균연비보다 증가한 경우라면 감소 가중치를 적용하여 연비의 증가분이 축소되게 처리하며, 산출한 평균연비가 이전 평균연비보다 감소하거나 동일한 경우라면 가중치를 적용하지 않도록 처리하게 프로그램되어져 있다.In addition, if the calculated average fuel economy is greater than the previous average fuel economy, the controller 14 applies a reduction weight to reduce the increase in fuel economy, and if the calculated average fuel economy is less than or equal to the previous average fuel economy, It is programmed to take care not to apply.

참조부호 12는 이전 평균연비 및 고정연비, 누적 주행거리 등의 데이터를 저장하는 데이터저장부를 나타낸다.Reference numeral 12 denotes a data storage unit for storing data such as previous average fuel economy, fixed fuel economy, and cumulative driving distance.

상기한 구성의 본 발명의 일실시예에 따른 주행가능거리 연산용 연비의 표시장치의 기능과 작용을 첨부된 도면을 참조하여 상세하게 설명한다. With reference to the accompanying drawings, the function and operation of the display device for driving distance calculation fuel economy according to an embodiment of the present invention of the above configuration will be described in detail.

도 2는 본 발명의 일실시예에 따른 주행가능거리 연산용 연비의 표시장치의 신호흐름을 도시한 플로우챠트이다.FIG. 2 is a flowchart illustrating a signal flow of a display device for driving distance calculation according to an embodiment of the present invention.

먼저, 본 발명의 일실시예에 따른 주행가능거리 연산용 연비의 표시장치(2)는 연료량 검출부(4)의 잔량 변화가 감지되는 지를 판단하여 급유감지가 이루어지는 지를 판단한다.First, the display device 2 for driving distance calculation according to an embodiment of the present invention determines whether fueling is detected by determining whether a change in the remaining amount of the fuel amount detection unit 4 is detected.

만약, 급유가 감지된 경우라면, 연료잔량의 변동으로 차후 운행시의 연비에 변동이 발생될 수 있으므로 재급유시에는 변동연비를 재산출하고, 고정연비를 적용한 평균 연비도 재산출한다.If refueling is detected, fluctuations in fuel levels may occur in subsequent operation due to fluctuations in the remaining fuel, and when refueling, the fuel is recalculated, and the average fuel consumption with fixed fuel consumption is also recalculated.

이때, 재급유시에는 급유 완료시 연료잔량을 검출하고, 평균 연비를 산출한 다음, 그 평균연비를 적용하여 주행가능거리를 산출한다.At this time, when refueling is completed, the fuel remaining amount at the completion of refueling is detected, the average fuel economy is calculated, and the running fuel distance is calculated by applying the average fuel economy.

그리고, 주행가능거리를 표시부(8)를 통해 표시한다.Then, the travelable distance is displayed on the display unit 8.

한편, 재급유가 이루어지지 않는 상태라면, 제어부(14)는 일정한 거리를 주행했거나 일정한 연료를 소모했는 지를 판단함으로써 연비 산출시점이 도래되었는 지를 판단한다.On the other hand, if refueling is not performed, the controller 14 determines whether the fuel consumption calculation point has arrived by determining whether the vehicle has traveled a certain distance or consumed a certain fuel.

위와 같은 연비 산출시점이 도래한 경우라면, 제어부(14)는 엔진 ECU(5)와 CAN 통신을 수행하여 연료소모량을 검출하고 차속검출부(6)를 통해 누적연산된 주행거리를 검출한다.When the fuel consumption calculation point as described above arrives, the controller 14 performs CAN communication with the engine ECU 5 to detect the fuel consumption amount and detect the accumulated travel distance through the vehicle speed detection unit 6.

그리고, 해당 연료소모량과 주행거리를 이용하여 변동연비를 산출하는 바, 이전연비와 비교하여 연비가 증가되었는 지를 판단하고, 연비가 이전 평균연비보다 증가한 경우라면 감소 가중치를 적용하여 연비의 증가분이 축소되게 처리한다.The fuel consumption and the mileage are used to calculate the variable fuel economy, which determines whether the fuel economy has increased compared to the previous fuel economy, and if the fuel economy has increased from the previous average fuel economy, the increase in fuel economy is reduced by applying a weight reduction. Process it.

이를 통해, 본 발명의 일실시예에 따른 주행가능거리 연산용 연비의 표시장치(2)는 급격한 연비의 변동을 방지하여 산출된 연비나 또는 주행가능거리에 대한 사용자의 신뢰도를 향상시킬 수 있게 한다.Through this, the display apparatus 2 for driving distance calculation fuel economy according to an embodiment of the present invention may prevent the sudden change in fuel efficiency and improve the user's reliability with respect to the fuel economy or the driving distance calculated. .

한편, 본 발명의 실시예에 따른 주행가능거리 연산용 연비의 표시장치는 단지 상기한 실시예에 한정되는 것이 아니라 그 기술적 요지를 이탈하지 않는 범위내에서 다양한 변경이 가능하다. On the other hand, the display of the fuel consumption for driving distance calculation according to the embodiment of the present invention is not limited to the above embodiment, but various modifications can be made within the scope not departing from the technical gist.

In the vehicle's mileage indicator,
A fuel amount detector detecting a fuel remaining amount of the fuel tank;
An engine ECU which detects a fuel consumption amount which is an injection amount of the injector;
A vehicle speed detector detecting a vehicle speed;
A controller configured to calculate a variable fuel economy based on data output from the fuel amount detector, an engine ECU, and a vehicle speed detector, and calculate an initial travelable distance after refueling based on the calculated variable fuel consumption and a set fixed fuel economy; And
It includes a display unit for displaying a signal for the driving distance output from the controller in numerical value,
The variable fuel economy is calculated by dividing the accumulated running distance detected and accumulated by the vehicle speed detector by the fuel consumption received from the engine ECU,
The control unit calculates the variable fuel consumption when refueling, refueling, driving at a predetermined distance, or when a predetermined amount of fuel is consumed.
Whenever the variable fuel economy is calculated, the average fuel economy is calculated through the calculation of (fixed fuel economy + variable fuel economy) / 2, and the average fuel efficiency is applied to calculate the driving distance.
If the calculated average fuel economy is increased than the previous average fuel economy, the increase in fuel economy is reduced by applying a reduction weight, and if the calculated average fuel economy is less than or equal to the previous average fuel economy, the program is processed so as not to apply a weight. A fuel economy display device for driving distance calculation, characterized in that.
