본 발명은 차량용 연료 게이지의 응답성 제어방법에 관한 것으로서, 더욱 상세하게는 위성으로부터 수신받은 네비게이션 시스템에 표시되는 차량의 위치 정보 및 각종 도로의 정보등(직진로, 굽은 도로, 비포장도로, 경사로)을 이용하여 연료게이지의 응답성을 제어하도록 함으로써 실제 주행 환경을 반영하고, 좀더 미세하게 제어할 수 있도록 한 네비게이션 시스템을 이용한 차량용 연료 게이지의 응답성 제어방법에 관한 것이다.The present invention relates to a responsiveness control method for a fuel gauge for a vehicle, and more particularly, vehicle position information and various road information displayed on a navigation system received from a satellite (for example, straight roads, curved roads, unpaved roads, and ramps). It relates to a responsiveness control method of a fuel gauge for a vehicle using a navigation system to reflect the actual driving environment by controlling the responsiveness of the fuel gauge using the navigation system and to control more finely.

상기 도면에 도시된 바와 같이, 일반적으로 차량의 연료 게이지(30)는 연료량감지센서(40)에 의해 연료탱크내의 연료량을 감지하고, 상기 연료량감지센서(40)의 연료량감지신호를 입력받아 이를 연료 게이지(30)에 출력시켜 표시토록 제어하는 제어부인 ECU(Electronic control unit)(20)가 구비되어 이루어져 있다.As shown in the figure, in general, the fuel gauge 30 of the vehicle detects the amount of fuel in the fuel tank by the fuel amount sensor 40, and receives the fuel amount detection signal of the fuel amount sensor 40 to receive the fuel ECU (Electronic control unit) 20 which is a control unit for output to the gauge 30 to control the display is provided.

상기 차량의 연료 게이지는 연료탱크내의 연료량의 변화에 따라 이를 연료 게이지에 출력하는 데에 있어 연료 게이지의 응답성에 따라 운전자는 빠르게 또는 느리게 연료량의 변화를 확인할 수가 있게 된다.The fuel gauge of the vehicle outputs the fuel gauge to the fuel gauge in accordance with the change in the fuel amount in the fuel tank, so that the driver can check the fuel amount quickly or slowly according to the responsiveness of the fuel gauge.

즉, 상기 연료량감지센서로부터 연료량감지신호를 입력받은 ECU는 상기 연료 게이지에 일정 지연시간을 두고 측정된 연료량을 표시하도록하는 제어신호를 송신하게 됨으로써, 상기 지연시간에 따라 연료 게이지에는 연료량의 변화가 빠르게 또는 느리게 표시되는 것이다.That is, the ECU receiving the fuel level detection signal from the fuel level detection sensor transmits a control signal for displaying the measured fuel amount with a predetermined delay time to the fuel gauge, so that the fuel gauge changes in the fuel gauge according to the delay time. It is displayed quickly or slowly.

이러한 상기 연료 게이지의 응답성은 차량의 외부 환경에 따라 조정되어지는데, 일반적으로 주유 시 발생하는 연료량 변화에는 빠른 응답성을 보이고 주행 중 회전 또는 경사로 등, 주행 상태에 따라 발생하는 연료량 변화에는 느린 응답성을 갖게 된다. 또한 비탈길 주차 및 정차 시 차체가 기울어짐에 따른 연료량 변화에는 연료 게이지가 응답하지 않도록 조정된다.The responsiveness of the fuel gauge is adjusted according to the external environment of the vehicle. In general, the response of the fuel gauge is quick. Will have In addition, the fuel gauge is adjusted so that the fuel gauge does not respond to changes in the fuel amount caused by the tilting of the vehicle body during slope parking and stopping.

이러한 연료 게이지의 응답성 조정은 다양한 종류의 연료 게이지에 따라 고유의 알고리즘을 적용하여 각각의 장단점을 가지나,These fuel gauge responsiveness adjustment has its own advantages and disadvantages by applying a unique algorithm according to various fuel gauges.

대체적으로 그 응답성 조정이 미세하지 못하고 포괄적으로 이루어지며, 실제 주행 환경을 반영하기에는 무리가 있어 보다 정확한 연료량의 변화를 운전자는 확인할 수가 없었다.In general, the responsiveness adjustment is not fine but comprehensive, and it is difficult to reflect the actual driving environment, so that the driver cannot confirm the change in fuel amount more accurately.

The ECU 20 receiving the fuel amount detection signal sensed by the sensor 40 is enabled by sending a control signal indicating the fuel amount to the fuel gauge 30 immediately without a separate delay time.

또한, 네비게이션 시스템(10)이 현재 주행중인 도로에 대한 각종 정보, 즉 대관령과 같은 경사가 심한 경사로를 주행중인가, 아님 고속도로와 같은 직진로를 주행중인가, 또는 국도의 굽은 도로를 주행중인가, 시골의 비포장 도로를 주행중인가 등의 정보를 ECU(20)에 송신하게 되고, 상기의 도로에 대한 각종 정보를 수신한 ECU(20)는 각각의 주행상태에 따라 연료 게이지(30)의 응답성이 다르도록 제어신호를 보내어 조정할 수 있도록 한 것이다.In addition, the navigation system 10 is driving a variety of information on the road currently being driven, that is, driving on a steep slope such as Daegwallyeong, or driving on a straight road such as a highway, or driving a curved road on a national road, The ECU 20 transmits information such as whether the vehicle is driving on an unpaved road, and the ECU 20 having received various kinds of information on the road has a different responsiveness of the fuel gauge 30 according to each driving state. It is to control by sending control signal.

즉, 각각의 조건에 따라 차량의 연료 게이지(30)의 응답성을 미세하게 조정할 수가 있게 된다.That is, the responsiveness of the fuel gauge 30 of the vehicle can be finely adjusted according to each condition.

따라서, 차량의 실제 주행 환경을 최대한 고려하여 차량의 연료 게이지(30)의 응답성을 제어할 수가 있게 되므로 보다 정확한 연료의 변화량을 운전자는 확인할 수가 있게 된다.Therefore, since the response of the fuel gauge 30 of the vehicle can be controlled in consideration of the actual driving environment of the vehicle as much as possible, the driver can check the change amount of the fuel more accurately.
