Abstract

PURPOSE: A fuel sender evaluating method is provided to precisely evaluate a fuel sender by measuring voltage between the fuel sender and a fuel gauge when measuring an amount of fuel. CONSTITUTION: An amount of fuel remaining in a fuel tank is measured by measuring an amount of consumed fuel(ST11). Then, voltage between a sender including first to third segments and a fuel gauge is measured, thereby measuring an amount of fuel from one segment to other segment of the sender(ST21,ST22). After that, the amount of fuel remaining in the fuel tank is compared with the amount of fuel measured in the segment of the sender, thereby determining whether or not the amount of fuel is precisely measured(ST30). If the amount of fuel is not precisely measured, an error of the segment is measured(ST42).

Description

퓨얼 센더 평가방법 {FUEL SENDER APPRAISING METHOD}Fuel sender evaluation method {FUEL SENDER APPRAISING METHOD}

본 발명은 퓨얼 센더 평가방법에 관한 것으로서, 보다 상세하게는 연료량 측정과 동시에 센더와 연료 게이지 간의 전압을 측정하여 평가의 정도(精度)를 향상시키고 양산시 발생되는 문제를 미연에 방지하는 퓨얼 센더 평가방법에 관한 것이다.The present invention relates to a fuel sender evaluation method, and more particularly, a fuel sender evaluation method for measuring a fuel amount and simultaneously measuring a voltage between the sender and the fuel gauge to improve the accuracy of evaluation and to prevent problems occurring during mass production. It is about.

차량의 운전석에는 도 1에 도시된 바와 같은 크러스터(1)가 구비되어 있으며, 이 크러스터(1)에는 차량의 각 부분에서 감지한 신호로 각종 운행 상태를 표시하는 게이지들, 즉 온도 게이지(3), 차속 게이지(5), 엔진 회전수 게이지(7), 그리고 연료 게이지(9) 등이 구비되어 있다.The driver's seat of the vehicle is provided with a cluster 1 as shown in FIG. 1, the cluster 1 having gauges indicating various driving states by signals detected by each part of the vehicle, that is, a temperature gauge 3. , A vehicle speed gauge 5, an engine speed gauge 7, a fuel gauge 9, and the like.

이 연료 게이지(9)에 연료량을 표시하기 위하여 연료탱크(11)에 센더(13)가 내장되어 있다.The sender 13 is built in the fuel tank 11 to display the fuel amount on the fuel gauge 9.

이 센더(13)는 연료 게이지(9)에 전기적으로 연결되며 도 2에 도시된 바와 같이, 특정 연료량에서 특정 저항값을 가지는 다수의 세그먼트, 즉 제1, 2, 3 세그먼트(15, 17, 19)로 구성되어 있다.This sender 13 is electrically connected to the fuel gauge 9 and, as shown in FIG. 2, a plurality of segments, i.e., first, second and third segments 15, 17 and 19, having a specific resistance value at a particular fuel amount. It consists of).

즉, 제1 세그먼트(15)는 설계 사양의 연료량이 38~40L인 구간에 위치하며 체크 포인트인 연료량 39L에서 설계저항이 5Ω이고, 제2 세그먼트(17)는 설계 사양의 연료량이 36~38L인 구간에 위치하며 체크 포인트인 연료량 37L에서 설계저항이 10Ω이고, 제3 세그먼트(19)는 설계 사양의 연료량이 34~36L인 구간에 위치하며 체크 포인트인 연료량 35L에서 설계저항이 20Ω이다. 여기서 각 체크 포인트는 제1, 2, 3 세그먼트(15, 17, 19)의 중심에 유면(21)이 일치된 것을 상정한다.That is, the first segment 15 is located in the section of 38-40L fuel amount of the design specification, the design resistance is 5Ω at the fuel amount 39L which is the check point, and the second segment 17 is 36-38L fuel amount of the design specification. The design resistance is 10 Ω in the fuel quantity 37L, which is a check point, and the third segment 19 is located in the section of fuel quantity 34-36L in the design specification, and the design resistance is 20 Ω, in the fuel amount 35L, the check point. Here, each check point assumes that the oil level 21 coincides with the center of the first, second, and third segments 15, 17, and 19.

이 센더(13)와 연료 게이지(9)의 메칭 성능을 평가하는 퓨얼 센더 평가방법은 연료탱크(11)에 규정량의 연료를 넣은 상태에서 소모되는 연료량을 센서로 감지하여 연료탱크(11) 내의 실제 연료량을 파악하고, 이렇게 파악된 연료량을 기준으로 이 연료량에 해당하는 센더(13)의 설계 저항값과 센더(13)의 실제 측정 저항값과의 일치 정도로 센더(11)를 평가한다.The fuel sender evaluation method for evaluating the matching performance of the sender 13 and the fuel gauge 9 detects the amount of fuel consumed in a state in which a predetermined amount of fuel is put into the fuel tank 11 and detects the amount of fuel in the fuel tank 11. The actual fuel amount is grasped, and the sender 11 is evaluated to the degree of agreement between the design resistance value of the sender 13 corresponding to this fuel amount and the actual measured resistance value of the sender 13.

즉, 도 3에 도시된 바와 같이 제1, 2, 3 세그먼트(15, 17, 19)의 각 체크 포인트 39L, 37L, 35L에서 각 측정 저항값이 5Ω, 10Ω, 20Ω이라면 센더(11)의 설계 저항값과 동일하므로 센더(11)는 정상으로 평가된다.That is, as shown in FIG. 3, when the measured resistance values are 5Ω, 10Ω, and 20Ω at the check points 39L, 37L, and 35L of the first, second, and third segments 15, 17, and 19, the design of the sender 11 is performed. Since the same as the resistance value, the sender 11 is evaluated as normal.

그러나, 이와 같은 퓨얼 센더 평가방법은 각 세그먼트가 관리 영역의 어떤 지점에 위치하는 지 알 수 없고, 각 세그먼트의 중앙에 유면(21)을 일치시키기 어려운데, 센서를 통하여 파악된 연료량과 이 연료량을 기준으로 하는 센더(13)의 설계 저항값과 센더(13)의 측정 저항값을 비교하여 평가하므로 센더(13)의 각 세그먼트가 설계 저항값에 상응하는 연료량에서 어느 정도 벗어나는지 그 편차를 정확히 확인할 수 없게 하고, 이로 인하여 센더(13)에 의한 연료 게이지(9)의 지시 불일치 문제를 정확히 확인할 수 없게 한다.However, this fuel sender evaluation method does not know where each segment is located in the management area, and it is difficult to match the oil level 21 at the center of each segment. Since the design resistance value of the sender 13 and the measured resistance value of the sender 13 are evaluated and evaluated, the deviation of each segment of the sender 13 from the amount of fuel corresponding to the design resistance value can be accurately determined. This makes it impossible to accurately identify the problem of indication mismatch of the fuel gauge 9 by the sender 13.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로서, 본 발명의 목적은 연료량 측정과 동시에 센더와 연료 게이지 간의 전압을 측정하여 평가의 정도(精度)를 향상시키고 양산시 발생되는 문제를 미연에 방지하는 퓨얼 센더 평가방법을 제공한다.Therefore, the present invention has been invented to solve the above problems, and an object of the present invention is to measure the voltage between the sender and the fuel gauge at the same time as measuring the fuel amount, thereby improving the accuracy of evaluation and not causing problems in mass production. It provides a method for evaluating fuel senders.

도 4는 본 발명에 따른 차량의 크러스터와 퓨얼 센더의 연결 상태 개념도로서, 그 전체적인 구성은 종래의 구성과 유사하며 센더(41)와 연료 게이지(43)사이에서 전압을 측정하는 전압계(45)의 구성이 추가되어 있다. 운전석의 크러스터(47)에 온도 게이지(49), 차속 게이지(51), 엔진 회전수 게이지(53)가 구비된 구성은 종래의 구성과 동일하므로 이들 구성에 대한 구체적인 설명을 생략한다.4 is a conceptual diagram of the connection between the cluster and fuel sender of the vehicle according to the present invention, the overall configuration of which is similar to the conventional configuration and of the voltmeter 45 measuring the voltage between the sender 41 and the fuel gauge 43. The configuration is added. Since the structure provided with the temperature gauge 49, the vehicle speed gauge 51, and the engine speed gauge 53 in the cluster crest 47 of a driver's seat is the same as a conventional structure, detailed description of these structures is abbreviate | omitted.

이 전압계(45)를 구비한 구성의 퓨얼 센더 평가 방법은 도 5에 도시된 바와 같다.The fuel sender evaluation method of the structure provided with this voltmeter 45 is as shown in FIG.

먼저, 센더(41)를 평가하기 위하여, 종래와 같이 연료탱크(55)에 규정량의 연료를 넣어둔다.First, in order to evaluate the sender 41, a prescribed amount of fuel is put in the fuel tank 55 as in the prior art.

이 상태에서 센서를 이용하여 차량 운행으로 소비된 연료의 소모량을 측정하여(ST11) 연료탱크(55)에 남아 있는 실제 연료량(a)을 측정한다(ST12).In this state, the actual fuel amount a remaining in the fuel tank 55 is measured by measuring the consumption amount of the fuel consumed by driving the vehicle using the sensor (ST11).

이 단계와는 별도로 센더(41)와 연료 게이지(43) 사이의 전압을 측정하여(ST21), 도 6에 도시된 바와 같이, 유면(56)이 센더(41)의 한 세그먼트에서 다른 세그먼트로 넘어갈 때의 연료량(b)을 측정한다(ST22).Apart from this step, the voltage between the sender 41 and the fuel gauge 43 is measured (ST21), so that the oil surface 56 can pass from one segment of the sender 41 to another as shown in FIG. The amount of fuel b at the time of measurement is measured (ST22).

이를 위하여 센더(41)는 제1, 2, 3 세그먼트(57, 59, 61)의 저항으로 구성되어 있다. 이 제1, 2, 3 세그먼트(57, 59, 61)는 연료탱크(55)에서 각각 설계 사양의 다른 구간을 지시하도록 배치되어 있다.To this end, the sender 41 is composed of resistors of the first, second, and third segments 57, 59, and 61. These first, second and third segments 57, 59 and 61 are arranged in the fuel tank 55 to indicate different sections of the design specification, respectively.

즉, 제1 세그먼트(57)는 설계 사양의 연료량이 38~40L인 구간에 위치하며, 체크 포인트인 연료량 39L에서 제1 세그먼트(57)의 설계 전압/저항은 1.0V/5Ω로 설정되어 있다. 제1 세그먼트(57)는 실제 연료량이 38.5~40.5L인 구간에 위치하고 있다.That is, the 1st segment 57 is located in the section whose fuel amount of a design specification is 38-40 L, and the design voltage / resistance of the 1st segment 57 is set to 1.0V / 5 ohms in the fuel amount 39L which is a check point. The first segment 57 is located in the section where the actual amount of fuel is 38.5-40.5L.

이 제1 세그먼트(57)의 하측에 위치하는 제2 세그먼트(59)는 설계 사양의 연료량이 36~38L인 구간에 위치하며, 체크 포인트인 연료량 37L에서 제2 세그먼트(59)의 설계 전압/저항은 1.5V/10Ω로 설정되어 있다. 제2 세그먼트(59)는 실제 연료량이 36.5~38.5L인 구간에 위치하고 있다.The second segment 59 located below the first segment 57 is located in a section of 36 to 38 L of fuel in the design specification, and the design voltage / resistance of the second segment 59 at the check point of fuel amount 37L. Is set to 1.5V / 10Ω. The second segment 59 is located in a section in which the actual fuel amount is 36.5 to 38.5L.

그리고, 제2 세그먼트(59)의 하측에 위치하는 제3 세그먼트(61)는 설계 사양의 연료량이 34~36L인 구간에 위치하며, 체크 포인트인 연료량 35L에서 제3 세그먼트(61)의 설계 전압/저항은 2.0V/20Ω로 설정되어 있다. 제3 세그먼트(61)는 실제 연료량이 34.5~36.5L인 구간에 위치하고 있다.The third segment 61 located below the second segment 59 is located in a section having a fuel specification of 34 to 36L in the design specification, and the design voltage / of the third segment 61 at the fuel amount 35L as the check point. The resistance is set to 2.0V / 20Ω. The third segment 61 is located in a section where the actual amount of fuel is 34.5 to 36.5L.

한편, 여기에 예시된 설계 사양들은 차량의 사양에 따라 얼마든지 변경될 수 있다.On the other hand, the design specifications exemplified herein may be changed as much as the specification of the vehicle.

이러한 센더(41) 측 세그먼트로 측정한 연료량(b)과 센서로 실제 측정한 연료량(a)을 상호 비교함으로서, 실제 연료의 잔량에 대한 센더(41) 측 세그먼트로 측정한 연료량(b)이 정확한지를 판단하게 된다(ST30).By comparing the fuel amount b measured by the sender 41 side segment with the fuel amount a actually measured by the sensor, whether the fuel amount b measured by the sender 41 side segment with respect to the actual amount of fuel remaining is correct. It is determined (ST30).

이 판단에서 센더(41) 측 측정 연료량(b)이 실제 센서로 측정한 연료량(a)과 일치되면 센더(41)측 제1, 2, 3 세그먼트(57, 59, 61) 중 해당 세그먼트를 정상으로 판정한다(ST41).In this determination, if the measured fuel amount b on the sender 41 side matches the fuel amount a measured by the actual sensor, the corresponding one of the first, second, and third segments 57, 59, and 61 on the sender 41 side is normal. It determines with (ST41).

상기 판단(ST30)에서 세그먼트의 측정 연료량(b)이 정확하지 않을 때에는 센더(41) 측 측정 연료량(b)과 센더 측 설계 전압에 따른 연료량(c)의 차이로 해당 세그먼트의 오차 크기를 파악한다(ST42).When the measured fuel amount b of the segment is not accurate in the determination ST30, the error magnitude of the segment is determined by the difference between the measured fuel amount b of the sender 41 side and the fuel amount c according to the sender design voltage. (ST42).

상기와 같은 조건으로 평가한 결과 도 7과 같은 평가 결과를 얻었다면, 센더(41)는 정해진 설계 사양보다 0.5L 높게 셋팅되어 있다는 것을 알 수 있고, 이 값만큼 센더(41)의 위치를 낮게 셋팅함으로서 센더(41) 평가의 정도(精度)를 높일 수 있게 된다.As a result of evaluating under the above conditions, if the evaluation result as shown in FIG. 7 is obtained, it can be seen that the sender 41 is set to 0.5L higher than the predetermined design specification, and the position of the sender 41 is set as low as this value. As a result, the accuracy of the evaluation of the sender 41 can be increased.

이와 같이 본 발명의 퓨얼 센더 평가방법은 센서로 실제 연료량을 측정하는 종래 방법에 센더와 연료 게이지 사이의 전압을 측정함으로서 센더의 저항값 및 전압을 함께 측정하여 연료량을 측정함으로서, 저항값만으로 연료량을 측정하는 종래방법과 달리 센더의 전반적인 오차까지 찾아 낼 수 있고, 오차를 갖는 세그먼트의 수정 범위까지 찾아냄으로서, 평가의 정도를 높이고 연료 게이지의 지시성을 향상시킬 수 있다. 따라서 운전자 및 승객은 안심하고 차량을 운행할 수 있게 된다.As described above, the fuel sender evaluation method of the present invention measures the fuel amount by measuring the resistance value and the voltage of the sender by measuring the voltage between the sender and the fuel gauge in the conventional method of measuring the actual fuel amount using a sensor, thereby measuring the fuel amount using only the resistance value. Unlike the conventional method of measuring, the overall error of the sender can be found, and the correction range of the segment having the error can be found, thereby increasing the degree of evaluation and improving the indication of the fuel gauge. Therefore, the driver and the passenger can operate the vehicle with confidence.
