It relates to a brake assistance device of a vehicle using the fuel supply interruption.
일반적으로 차량의 주행중 감속 또는 정지를 위하여 브레이크장치를 설치하였다. 이는 주행중 급감속을 하더라도 연료의 공급을 계속적으로 이루어지도록 되어 있어 연료의 낭비요인이 되는 문제점이 있었다.Generally, a brake device is installed to reduce or stop the vehicle while driving. This has been a problem that the fuel is a waste of fuel because the supply of the fuel is to be continuously made even if a sudden deceleration during driving.
따라서 종래에는 감속시 설정된 엔진의 회전수이상에서는 연료의 절감을 위하여 연료의 공급을 일시적으로 중단시키는 기능이 추가되어 있다.Therefore, in the related art, a function of temporarily stopping the supply of fuel to reduce the fuel is added at a speed higher than the engine speed set during deceleration.
본 고안은 주행속도의 감속시 크랭크샤프트의 각속도변화가 설정값이상일 경우 급제동으로 판단하고 엔진의 회전수에 관계없이 연료공급을 중단시켜 토오크의 급감소로 브레이크의 보조기능을 하도록 하므로서 제동능력을 높이고자 연료공급중단을 이용한 차량의 브레이크보조장치를 제공하는데 그 목적이 있다.When the angular speed change of the crankshaft is higher than the set value at the time of deceleration of the running speed, the present invention determines that it is sudden braking and stops the fuel supply regardless of the number of engine revolutions. It is an object of the present invention to provide a brake assist device for a vehicle using fuel supply interruption.
본 고안은 이러한 목적을 달성하기 위하여, 크랭크사프트의 부근에 설치된 크랭크샤프트포지션센서부에 경사지게 설치하여 연속적으로 회전하는 크랭크샤프트의 각속도를 감지하는 각속도감지센서와, 각속도감지센서의 감지신호를 받아서 크랭크샤프트의 평균 각속도를 연산하는 각속도연산부와, 각속도연산부에서 연산된 평균 각속도의 신호를 받아서 각속도 감속률을 계산하는 감속률연산부와, 감속률연산부의 신호를 받아서 설정값이상으로 급감속되는 경우 연료의 공급을 중단하는 연료공급중단부와, 각속도 및 감속률연산부와 연료 공급중단부를 각각 제어하는 전자제어부로 연료공급중단을 이용한 차량의 브레이크보조장치를 구성한 것이 본 고안의 특징이다.In order to achieve this object, the present invention is installed inclined to the crankshaft position sensor unit installed in the vicinity of the crankshaft, the crankshaft sensor for detecting the angular velocity of the continuously rotating crankshaft, and receiving the detection signal of the angular velocity sensor The angular velocity calculator calculates the average angular velocity of the shaft, the deceleration rate calculator calculates the angular velocity deceleration rate by receiving the signal of the average angular velocity calculated by the angular velocity calculator, and receives the signal of the deceleration rate calculator. It is a feature of the present invention that the brake assistance device of the vehicle using the fuel supply stop is configured by the fuel supply stop part for stopping the supply, and the electronic control unit for controlling the angular speed and deceleration rate calculation unit and the fuel supply stop part, respectively.
이하 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도면 제1도에서, 크랭크샤프트(1)의 부근에 설치된 크랭크샤프트포지션센서부에 경사지게 설치하여 연속적으로 회전하는 크랭크샤프트(1)의 각속도를 감지하는 각속도감지센서(2)와, 각속도감지센서(2)의 감지신호를 받아서 크랭크샤프트(1)의 평균 각속도를 연산하는 각속도연산부(3)와, 각속도연산부(3)에서 연산된 평균 각속도의 신호를 받아서 각속도 감속률을 계산하는 감속률연산부(4)와, 감속률연산부(4)의 신호를 받아서 입력된 데이타와 비교판단한 뒤 설정값이상으로 급감속되는 경우 연료의 공급을 중단하는 전자제어부(5)로 연료 공급중단을 이용한 차량의 브레이크보조장치를 구성한다.In FIG. 1, an angular velocity detection sensor 2 and an angular velocity detection sensor for detecting an angular velocity of a continuously rotated crankshaft 1 by inclining the crankshaft position sensor portion installed near the crankshaft 1 are shown in FIG. An angular velocity calculating section 3 for receiving the detection signal of 2) and calculating an average angular velocity of the crankshaft 1, and a deceleration rate calculating section for receiving an average angular velocity signal calculated by the angular velocity calculating section 3 and calculating the angular velocity deceleration rate (4). ) And the brake assistance device of the vehicle using the fuel supply interruption to the electronic control unit 5 which stops the supply of fuel when the speed decreases more than the set value after receiving the signal of the deceleration rate calculating unit 4 and comparing it with the input data. Configure
이와같이 구성된 본 고안은, 엔진의 정상적인 구동시에는 연료의 게속적인 공급이 이루어지나, 급제동시 크랭크샤프트(1)의 각속도가 급격하게 변하게 되므로 이때 각속도감지센서(2)가 크랭크샤프트(1)의 각속도를 감지하게 되며, 각속도감지센서(2)에서 감지된 각속도변화 신호를 받아서 각속도연산부(3)가 크랭크샤프트(1)의 평균 각속도를 연산하게 되고, 각속도연산부(3)에서 연산된 평균 각속도의 신호를 받아서 감속률연산부(4)가 각속도 감속률을 계산하게 되며, 감속률연산부(4)의 신호를 받아서 전자제어부(5)가 입력된 데이타와 비교판단한 뒤 설정값이상으로 급감속되는 경우 연료의 공급을 중단하게 되는 것이다.According to the present invention, the angular velocity of the crankshaft (1) is rapidly changed because the angular velocity of the crankshaft (1) changes rapidly during normal braking. The angular velocity change unit 3 receives the angular velocity change signal detected by the angular velocity sensor 2, and the angular velocity calculator 3 calculates an average angular velocity of the crankshaft 1 and the signal of the average angular velocity calculated by the angular velocity calculator 3. When the deceleration rate calculation unit 4 calculates the angular velocity deceleration rate and receives the signal from the deceleration rate operation unit 4, the electronic control unit 5 compares the input data and rapidly decelerates above the set value. The supply will be stopped.
따라서 연료의 공급중단시 브레이크의 작동과 별개로 엔진의 토오크의 급감소로 인하여 보조브레이크의 기능을 수행하도록 하는 것이다.Therefore, to stop the supply of fuel to perform the function of the auxiliary brake due to the sudden decrease in the torque of the engine, independent of the operation of the brake.
이와같이 본 고안은 주행속도의 감속시 크랭크샤프트의 각속도변화가 설정값이상일 경우 급제동으로 판단하고 엔진의 회전수에 관계없이 연료공급을 중단시켜 토오크의 급감소로 브레이크의 보조기능을 하도록 하므로서 제동능력을 높여 안전사고의 위험을 방지할 수가 있는 것이다.In this way, the present invention judges that the brake is suddenly braked when the angular speed change of the crankshaft is higher than the set value when the driving speed is reduced, and stops the fuel supply regardless of the engine speed. It is possible to prevent the risk of safety accidents.
