급제동시 브레이크와 클러치 동시작동 방지장치Prevent brake and clutch operation simultaneously during sudden braking

본 고안은 차량의 브레이크와 클러치에 관한 것으로서, 특히 차량의 급제동시 브레이크와 클러치가 동시에 작동되는 것을 방지할 수 있도록 고안된 급제동시 브레이크와 클러치 동시작동 방지장치에 관한 것이다.The present invention relates to a brake and a clutch of a vehicle, and more particularly, to a brake and clutch simultaneous operation prevention device designed to prevent the brake and the clutch from being operated at the same time during a sudden braking of the vehicle.

일반적으로, 전방차량의 갑작스런 정지나 전방물체가 돌출되는 경우 운전미숙으로 인해 운전자가 브레이크와 클러치를 동시에 작동시키면 차량의 제동거리가 길어짐에 따라 대형사고 발생하게 되는 등 그 사용상의 편의성을 제공하지 못하는 문제점이 있었다.In general, if the driver suddenly stops the front vehicle or protrudes the front object, if the driver operates the brake and the clutch simultaneously due to immature driving, a large accident occurs due to the long braking distance of the vehicle. There was a problem.

따라서, 본 고안은 이와 같은 문제점을 해결하기 위해 급제동시 브레이크와 클러치가 동시에 작동되지 않도록 하는 제어시스템을 구성시키므로서, 전방차량의 갑작스런 정지 또는 전방물체의 돌출현상에 운전자가 운전미숙으로 인해 브레이크와 클러치를 동시에 작동시키더라도 상기 클러치의 작동을 자동으로 정지시키도록 함에 따라 차량의 제동거리를 확보시킴은 물론 그 사용상의 편의성을 제공하고자 하는데 목적이 있는 것이다.Therefore, in order to solve such a problem, the present invention constitutes a control system that prevents the brake and the clutch from operating at the same time during sudden braking, so that the driver may be suddenly stopped or the protrusion of the front object may cause the driver to drive the brakes. Even if the clutch is operated at the same time to stop the operation of the clutch automatically to ensure the braking distance of the vehicle as well as to provide convenience for its purpose.

먼저, 차량의 급제동상태를 감지하는 가속도센서(10)와, 차량의 클러치 및 브레이크의 작동상태를 감지하는 클러치 및 브레이크 작동센서(20)(30)와, 상기 각 센서(10)(20)(30)에서 감지한 신호를 논리연산시킨 후 이의 연산신호를 출력시키는 논리연산부(40)와, 상기 논리연산부(40)에서 출력시킨 연산신호에 따라 차량의 급제동시 클러치의 작동을 정지시키고 브레이크만을 작동시킬 수 있도록 유압공급을 제어하는 유압제어부(50)와, 상기 유압제어부(50)의 제어동작에 따라 차량을 제동시키도록 차량의 브레이크에 유압을 공급시키는 브레이크 유압공급부(60)와, 차량의 급제동시 상기 유압제어부(50)의 제어동작에 따라 마스터실린더(도시하지 않음)와 플렉시블 호스(도시하지 않음)사이에 장착된 솔레노이드 밸브(도시하지 않음)를 닫힘동작시키면서 유압의 공급을 역상시키는 클러치 유압공급부(70)와, 차량의 급제동에 따른 정차시 상기 클러치 유압공급부(70)를 통해 차량의 클러치에 유압을 공급시킴과 동시에 차량시동의 꺼짐을 방지할 수 있도록 엔진 알피엠(RPM)을 감지하는 엔진토크 센서(80)로 구성된다.First, an acceleration sensor 10 for detecting a sudden braking state of a vehicle, a clutch and brake operation sensor 20, 30 for detecting an operation state of a clutch and a brake of the vehicle, and each of the sensors 10, 20 ( According to the logic operation unit 40 for outputting the operation signal and logic operation of the signal sensed in 30) and the operation signal output from the logic operation unit 40, the operation of the clutch is stopped and the brake is operated when the vehicle suddenly brakes. Hydraulic control unit 50 for controlling the hydraulic supply so that it can be made, brake hydraulic pressure supply unit 60 for supplying hydraulic pressure to the brake of the vehicle to brake the vehicle in accordance with the control operation of the hydraulic control unit 50, and braking of the vehicle When the solenoid valve (not shown) mounted between the master cylinder (not shown) and the flexible hose (not shown) is closed according to the control operation of the hydraulic control unit 50, The clutch hydraulic supply unit 70 for reversing the grade and the engine ALPM to supply the hydraulic pressure to the clutch of the vehicle through the clutch hydraulic supply unit 70 when the vehicle stops due to sudden braking of the vehicle and prevent the vehicle from starting off. It consists of an engine torque sensor 80 for detecting the RPM.

상기와 같이 구성된 본 고안의 일실시예를 설명하면 다음과 같다.Referring to one embodiment of the present invention configured as described above are as follows.

먼저, 차량이 주행되고 있는 상태에서 전방차량이 갑작스럽게 급제동을 하거나 또는 전방물체가 돌출되면서 차량을 급제동시키고자 하는 경우, 차량의 각 위치에 장착된 가속도센서(10)에서는 차량의 급제동상태를 감지한 후 이를 논리연산부(40)에 출력시킨다.First, when the vehicle ahead of the vehicle suddenly braking suddenly or if you want to suddenly brake the vehicle while the front object protrudes, the acceleration sensor 10 mounted at each position of the vehicle detects the braking state of the vehicle After that it is output to the logic operation unit 40.

그리고, 차량의 급제동시 운전자가 차량의 클러치 및 브레이크를 동시에 작동시키면, 클러치 및 브레이크 작동센서(20)(30)에서는 상기 작동된 클러치 및 브레이크의 작동상태를 감지한 후 이를 논리연산부(40)에 출력시키게 되므로서, 상기 논리연산부(40)에서는 상기 각 센서(10)에서 감지한 신호를 논리연산시킨 후 이의 연산신호를 유압제어부(50)에 출력시키게 된다.When the driver simultaneously operates the clutch and the brake of the vehicle at the time of sudden braking of the vehicle, the clutch and the brake operation sensors 20 and 30 detect the operating states of the operated clutch and the brake and transmit the same to the logic operation unit 40. Since it is output, the logical operation unit 40 performs a logical operation on the signal sensed by each sensor 10 and then outputs its operation signal to the hydraulic control unit 50.

이 때, 상기 유압제어부(50)에서는 입력된 연산신호에 따라 차량의 급제동시 클러치의 작동을 정지시키고 브레이크만을 작동시킬 수 있도록 브레이크 유압공급부(60) 및 클러치 유압공급부(70)를 제어하게 된다.At this time, the hydraulic control unit 50 controls the brake hydraulic pressure supply unit 60 and the clutch hydraulic pressure supply unit 70 to stop the operation of the clutch and operate the brake only when the vehicle suddenly brakes according to the input operation signal.

즉, 상기 유압제어부(50)의 제어동작에 따라 브레이크 유압공급부(60)에서는 차량을 제동시키도록 차량의 브레이크에 유압을 공급시키게 되며, 상기 클러치 유압공급부(70)에서는 차량의 급제동시 마스터실린더와 플렉시블 호스사이에 장착된 솔레노이드 밸브를 닫힘동작시켜 클러치로의 유압공급을 역상시키므로서, 차량의 급제동시 클러치의 작동을 방지시키게 되는 것이다.That is, according to the control operation of the hydraulic control unit 50, the brake hydraulic pressure supply unit 60 supplies hydraulic pressure to the brake of the vehicle to brake the vehicle, and the clutch hydraulic pressure supply unit 70 and the master cylinder at the time of sudden braking of the vehicle By closing the solenoid valve mounted between the flexible hose to reverse the hydraulic supply to the clutch, it prevents the operation of the clutch during sudden braking of the vehicle.

여기서, 차량의 급제동에 따른 정차시 엔진토크 센서(80)에서는 차량엔진의 RPM을 감지함과 동시에 이를 유압제어부(50)에 출력시키므로서, 상기 유압제어부(50)의 제어동작에 따라 클러치 유압공급부(70)에서는 차량의 클러치에 유압을 공급시켜 차량시동의 꺼짐을 방지시키게 되는 것이다.Here, the engine torque sensor 80 detects the RPM of the vehicle engine and outputs it to the hydraulic control unit 50 when the vehicle stops due to sudden braking of the vehicle, and thus the clutch hydraulic supply unit according to the control operation of the hydraulic control unit 50. In 70, the hydraulic pressure is supplied to the clutch of the vehicle to prevent the vehicle from turning off.

이상에서 설명한 바와 같이 본 고안은 급제동시 브레이크와 클러치가 동시에 작동되지 않도록 하는 제어시스템을 구성시키므로서, 전방차량의 갑작스런 정지 또는 전방물체의 돌출현상에 운전자가 운전미숙으로 인해 브레이크와 클러치를 동시에 작동시키더라도 상기 클러치의 작동을 자동으로 정지시키도록 함에 따라 차량의 제동거리를 확보시킴은 물론 그 사용상의 편의성을 제공하는 효과가 있는 것이다.As described above, the present invention constitutes a control system that prevents the brake and the clutch from operating simultaneously during sudden braking, so that the driver operates the brake and the clutch at the same time due to the driver's inexperience due to sudden stop of the front vehicle or protrusion of the front object. Even if it is made to stop the operation of the clutch automatically to ensure the braking distance of the vehicle as well as to provide the convenience of use.
