Description
본 발명은 차량용 출력제어장치에 관한 것으로서, 특히 차량의 주행상태를 계측하고 엔진의 동력발생조건, 변속기의 동력전달조건 및 냉각장치의 냉각제어조건을 고려하여 최적의 연료소비율을 유지할 수 있는 차량용 출력제어장치에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle output control device, and in particular, a vehicle output capable of maintaining an optimum fuel consumption rate by measuring a driving state of a vehicle and considering an engine power generation condition, a transmission power transmission condition of a transmission, and a cooling control condition of a cooling device. It relates to a control device.
차량용 출력제어장치는 차량의 주행상태를 계측하는 모듈의 신호를 받아 연료소비율이 최소가 되도록 엔진의 스로틀 및 변속조건을 변경시킨다. 연료소비율의 감소는 발열량의 감소로 이어지며 비례적으로 냉각장치의 냉각소요 동력의 감소로 이어진다.The vehicle output control device receives a signal from a module that measures the driving state of the vehicle and changes the throttle and shift conditions of the engine so that the fuel consumption rate is minimized. The reduction in fuel consumption leads to a decrease in heat generation and proportionately to a reduction in the cooling power of the cooling system.
도 1은 종래의 차량용 출력제어장치의 구성을 나타낸다. 1 shows a configuration of a conventional vehicle output control apparatus.
도 1에서 도시된 바와 같이, 가속페달(1)은 링키지(5)를 통해 엔진(3)의 스로틀(미도시)에 연결되어 있다. 운전자가 가속페달(1)을 누르면 그 압력에 비례하여 스로틀이 동작하고, 스로틀 동작에 의해 엔진(3)의 동작이 제어된다. 차량속도 센서(2)는 차량의 속도를 측정하고, 변속기(4)는 엔진(3)의 동작정보와 챠량속도를 입력받아 미리 정해진 변속맵을 이용하여 적절한 변속을 수행된다. As shown in FIG. 1, the accelerator pedal 1 is connected to a throttle (not shown) of the engine 3 via a linkage 5. When the driver presses the accelerator pedal 1, the throttle operates in proportion to the pressure, and the operation of the engine 3 is controlled by the throttle operation. The vehicle speed sensor 2 measures the speed of the vehicle, and the transmission 4 receives the operation information and the vehicle speed of the engine 3 and performs a proper shift using a predetermined shift map.
그러나, 종래의 출력제어장치는 운전자의 습관에 의존하는 것이므로 최적화된 연비 제어를 기대하기 어렵고, 외부주행조건의 불확실성과 엔진 및 변속기의 노후를 감안할 때 충분히 최적화된 연료소비율을 얻을 수 없다는 문제점이 있다. However, since the conventional output control device is dependent on the driver's habit, it is difficult to expect optimized fuel economy control, and there is a problem in that it is not possible to obtain a sufficiently optimized fuel consumption ratio in consideration of the uncertainty of the external driving conditions and the aging of the engine and the transmission. .
본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로서, 차량의 주행조건에 따라 엔진 및 변속기의 운전상태를 최적의 연비로 제어할 수 있는 차량용 출력제어 장치를 제공하는 것을 목적으로 한다. The present invention has been made to solve the above problems, and an object of the present invention is to provide an output control device for a vehicle that can control the driving state of the engine and the transmission in the optimum fuel economy according to the driving conditions of the vehicle.
이를 위해, 본 발명에 의한 차량용 출력제어장치는 차량속도 및 부하상태를 계측하는 차량 계측수단과, 엔진의 스로틀의 양, 회전속도 및 토크를 계측하는 엔진 계측수단과, 변속 및 록업 신호를 계측하는 변속기 계측수단과, 냉각공기의 유량, 냉각수의 온도 및 냉각팬의 회전속도를 계측하는 냉각장치 계측수단과, 상기 계측수단들로부터 출력된 데이터에 기초하여 엔진의 연비맵을 작성하는 연비맵 학습수단과, 상기 작성된 연비맵에서 차량의 주행상태에 대한 최적의 연비위치를 계산하는 최적연비위치 계산수단을 포함하여 구성된 것을 특징으로 한다.To this end, the vehicle output control apparatus according to the present invention includes a vehicle measuring means for measuring the vehicle speed and the load state, an engine measuring means for measuring the amount, rotation speed and torque of the engine, and the shift and lockup signal Transmission measurement means, cooling device measurement means for measuring the flow rate of the cooling air, the temperature of the cooling water and the rotational speed of the cooling fan, and fuel economy map learning means for creating a fuel economy map of the engine based on the data output from the measurement means. And an optimum fuel economy position calculating means for calculating an optimal fuel economy position with respect to the driving state of the vehicle in the created fuel economy map.
이하, 첨부된 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 의한 차량용 출력제어장치의 구성도를 나타낸다. 2 shows a configuration diagram of a vehicle output control apparatus according to the present invention.
도 2에서 도시된 바와 같이, 본 발명에 의한 차량용 출력제어장치는 차량의 주행상태를 파악하기 위해 차량속도 및 차량에 작용되는 부하를 계측하는 차량 계측수단(9)과, 엔진의 상태를 확인하기 위해 엔진의 스로틀의 양, 회전속도 및 토크를 계측하는 엔진 계측수단(10)과, 변속기의 상태를 확인하기 위해 변속 및 록업(lock-up)신호를 계측하는 변속기 계측수단(11)과, 방열량을 계산하기 위해 냉각공기의 유량, 냉각수의 온도 및 냉각팬의 회전속도를 계측하는 냉각장치 계측수단(12)과, 각 계측수단들(9-12)로부터 출력된 데이터를 처리하는 신호처리부(13)와, 신호처리부(13)에서 출력된 정보에 기초하여 엔진의 연비맵을 작성하는 연비맵 학습수단(15)과, 연비맵 학습수단(15)에 의해 작성된 연비맵에서 차량의 주행상태에 대한 최적의 연비위치를 계산하는 최적연비위치 계산수단(14)을 포함한다. As shown in FIG. 2, the vehicle output control apparatus according to the present invention includes a vehicle measuring means 9 for measuring a vehicle speed and a load applied to the vehicle in order to determine the driving state of the vehicle, and to check the state of the engine. Engine measuring means 10 for measuring the amount of throttle, rotational speed and torque of the engine, transmission measuring means 11 for measuring shift and lock-up signals to check the state of the transmission, and heat dissipation amount In order to calculate the flow rate of the cooling air, the temperature of the cooling water and the cooling device measuring means 12 for measuring the rotational speed of the cooling fan, and a signal processor 13 for processing the data output from the respective measuring means (9-12) And a fuel economy map learning means 15 for producing a fuel economy map of the engine based on the information output from the signal processor 13, and a fuel economy map created by the fuel economy map learning means 15 for the driving state of the vehicle. To calculate the optimum fuel economy Ever fuel comprises position calculation means (14).
도 3은 연비맵 학습수단(15)에서 엔진의 연비맵이 작성되는 학습과정을 나타낸다. 일반적으로 연비맵은 엔진의 특성 시험을 통해 획득되나, 엔진과 변속기의 노후화 및 작동환경의 변화에 따라 적절히 수정될 필요가 있다. 본 발명에서는 방열량과 발열량의 열평형을 정밀 계측하여 연비맵을 수정한다. 3 shows a learning process in which the fuel economy map of the engine is created in the fuel economy map learning means 15. In general, fuel economy maps are obtained by testing the characteristics of the engine, but they need to be appropriately modified as the engine and transmission age and the operating environment changes. In the present invention, the fuel economy map is corrected by precisely measuring the thermal balance of the heat dissipation amount and the heat generation amount.
도 3에서 도시된 바와 같이, 우선 각 계측수단들(9-12)로부터 차량상태 데이터가 입력된다(S1). 입력된 차량상태 데이터를 이용하여 엔진 및 변속기의 발열량을 계산한다(S2). As shown in Fig. 3, first, vehicle state data is input from the respective measurement means 9-12 (S1). The calorific value of the engine and the transmission is calculated using the input vehicle state data (S2).
엔진의 발열량은 연비맵의 특성, 연료의 발열특성 및 연소특성이 실제 구동력으로 전환되는 효율에 따라 다음과 같이 계산된다.The calorific value of the engine is calculated as follows according to the efficiency of converting the fuel economy map characteristics, the fuel heating characteristics and the combustion characteristics into actual driving force.
엔진 발열량 = 연비맵[스로틀, 엔진속도] ×(1-연소효율) ×연료량 ×(1-구동효율)Engine heating value = fuel consumption map [throttle, engine speed] × (1-combustion efficiency) × fuel amount × (1-drive efficiency)
변속기의 발열량은 엔진출력 및 변속효율에 따라 다음과 같이 계산된다. The heating value of the transmission is calculated as follows according to the engine power and the transmission efficiency.
변속기 발열량 = 엔진출력[스로틀, 엔진속도] ×(1-변속효율[차량속도, 엔진출력])Transmission heat output = engine output [throttle, engine speed] × (1-shift efficiency [vehicle speed, engine output])
그리고, 냉각장치 계측수단(12)에서 계측된 냉각공기의 유량, 냉각수 온도, 냉각팬의 회전속도를 이용하여 냉각장치에서 방열되는 방열량을 계산한다(S3).Then, the amount of heat dissipated from the cooling apparatus is calculated using the flow rate of the cooling air measured by the cooling apparatus measuring means 12, the cooling water temperature, and the rotational speed of the cooling fan (S3).
상기와 같이 구한 엔진 및 변속기의 발열량의 총합과 냉각장치의 방열량을 비교한다(S4). 즉, 발열량의 총합에서 방열량을 감산한 값이 오차범위 내에 있는지를 확인한다(발열량 - 방열량 < 오차범위).The total amount of heat generated by the engine and the transmission obtained as described above is compared with the amount of heat released by the cooling apparatus (S4). That is, it is checked whether the value obtained by subtracting the heat radiation amount from the sum of the heat generation amounts is within the error range (heat generation amount-heat radiation amount <error range).
감산결과 오차범위를 초과하면 발열효율을 조정하여 연비맵을 변경하고(S5), 오차범위 안에 있으면 현재의 연비맵 상태를 유지한다(S6). 발열량과 방열량의 비교를 통해 엔진의 발열효율을 조정하거나 현재 상태를 유지하면 그 결과를 메모리에 저장한다(S7).If the result of the subtraction exceeds the error range, the fuel efficiency map is changed by adjusting the heating efficiency (S5). If the error is within the error range, the current fuel consumption map state is maintained (S6). When the heat generation efficiency of the engine is adjusted or the current state is maintained by comparing the heat generation amount and the heat dissipation rate, the result is stored in the memory (S7).
최적연비위치 계산수단(14)은 메모리에 저장된 연비맵으로부터 현재 차량의 주행상태에 대한 최적의 연비위치를 계산한다. 도 3은 연비맵에서 최적연비위치 계산에 의해 연비점이 조정되는 것을 나타낸다. 최적연비점으로의 이동은 동일한 동력선도에서 이동하면서 대신에 변속단(N)과 스로틀(P%)를 변속단(n)과 스로틀(p%) 의 위치로 이동시키는 것을 의미한다.The optimum fuel economy position calculating means 14 calculates an optimal fuel economy position with respect to the driving state of the current vehicle from the fuel economy map stored in the memory. 3 shows that the fuel economy point is adjusted by calculating the optimum fuel economy position in the fuel economy map. Moving to the optimum fuel economy means moving the gear stage N and the throttle P% to the positions of the gear stage n and the throttle p% instead of moving on the same power line.
이와 같이 주행상태에 대한 최적연비위치의 계산에 의해 결과적으로 엔진 및 변속기의 상태가 최적으로 제어될 수 있다. As a result, the state of the engine and the transmission can be optimally controlled by the calculation of the optimum fuel consumption position for the driving state.
도 5는 차량의 주행거리당 연료소비를 누적하여 나타낸 그래프로서, 실선은 종래의 출력제어에 의한 결과를 나타내고, 파선은 본 발명의 출력제어에 의한 결과를 나타낸다. 도 5에서, 일정한 주행거리에서 본 발명의 누적연료소모량이 종래의 누적연료소모량보다 적음을 알 수 있다.FIG. 5 is a graph showing fuel consumption accumulated per vehicle travel distance, in which a solid line represents the result of the conventional output control, and a broken line represents the result of the output control of the present invention. In Figure 5, it can be seen that the cumulative fuel consumption of the present invention at a certain mileage is less than the conventional cumulative fuel consumption.
상기와 같이, 본 발명은 구동동력에 적합한 최적의 운전상태로 제어되어 연료소모량이 감소하고, 발열특성의 감소로 냉각장치의 소요동력을 최소화할 수 있는 효과가 있다. As described above, the present invention is controlled to the optimum operating state suitable for the driving power is reduced fuel consumption, there is an effect that can minimize the required power of the cooling device by reducing the heat generation characteristics.
또한, 본 발명은 엔진 또는 변속기의 노후화로 인한 작동상태의 변화가 운전조건에 미칠 수 있는 영향을 고려하여, 그 변화요소를 출력제어에 반영함으로써 최적의 출력제어를 얻을 수 있는 효과가 있다.In addition, the present invention has the effect of obtaining the optimum output control by reflecting the change factor in the output control in consideration of the effect that the change in the operating state due to the aging of the engine or the transmission may affect the operating conditions.
