Auxiliary brake devices have been used for braking each wheel so that the vehicle can be braked.
또한, 차량은 주행중 급제동을 할 경우 제동거리를 단축하기 위하여 급제동시 승차감을 저해하지 않는 범위에서 제동거리가 최대로 단축될 수 있게 여러 부품의 설계하고 이를 고려하여 각 부품을 차량에 장착한다.In addition, the vehicle is designed in accordance with the design of the various parts so that the braking distance can be reduced to the maximum in the range that does not impede the ride comfort during sudden braking in order to reduce the braking distance during sudden braking while driving each component is mounted on the vehicle.

Especially, the braking distance required during braking is as much as possible at a constant deceleration. By shortening the braking distance, it is possible to prevent an accident from colliding with an obstacle and a driving vehicle.

따라서, 본 고안은 속도 센서(12)와 브레이크 페달의 포지션 센서(14)의 신호를 입력하는 E. C. U. (10)가 고속 주행중 급제동되는 상태를 판단하게 하고, 판단된 신호에 따라 제어 신호를 출력하여 솔레노이드 밸브(20)를 제어하게 하며, 솔레노이드 배브(20)는 압축기(40)에 의해 저장된 고압의 에어를 차량의 앞범퍼(60)로 부터 분사될 수 있게 하며, 분사된 에어는 분사후 저장 압력이 일정 압력이 될 때까지 압축기(40)를 통해 고압 공기 저장 탱크(50)에 저장될 수 있게 함으로서 강한 제동력에 의해 타이어가 밀릴 경우 제동력을 한층 증대하여 제동거리를 최대한으로 단축하여 차량이 추돌 및 추락되는 위험으로부터 최대한 보호될 수 있게 구성하는 것을 그 특징으로 한다.Therefore, the present invention allows the ECU 10, which inputs the signals of the speed sensor 12 and the position sensor 14 of the brake pedal, to determine the state of sudden braking during high-speed driving, and outputs a control signal according to the determined signal to solenoid. In order to control the valve 20, the solenoid valve 20 allows the high pressure air stored by the compressor 40 to be injected from the front bumper 60 of the vehicle, the injected air is stored pressure after injection By allowing the compressor to be stored in the high-pressure air storage tank 50 through the compressor 40 until the pressure reaches a predetermined pressure, when the tire is pushed by the strong braking force, the braking force is further increased to shorten the braking distance to the maximum, thereby causing the vehicle to crash and fall. It is characterized in that it is configured so that it can be protected as much as possible from the danger.
상기한 목적을 실현하기 위한 본 고안의 구성에 대하여 예시한 도면을 참조하여 설명하면 다음과 같다.When explaining the configuration of the subject innovation for realizing the above object with reference to the drawings illustrated as follows.
예시된 도 1과 도 2에 도시된 바와 같이 차량의 고속 주행 상태를 판단하기 위한 차량의 속도 센서(12)의 신호와 브레이크 페달로부터 작용되는 급제동 상태를 판단하기 위하여 브레이크 페달의 포지션 센서(14) 신호의 신호를 입력하는 E. C. U. (10)를 설치하여 설정된 로직에 따라 고속 주행중 차량의 급제동 상태가 판단되면 제어 신호를 출력할 수 있게 한다.As illustrated in FIGS. 1 and 2, the position sensor 14 of the brake pedal to determine a signal of the speed sensor 12 of the vehicle for determining a high speed driving state of the vehicle and a sudden braking state applied from the brake pedal. An ECU 10 for inputting a signal of a signal is installed so that a control signal can be output when a sudden braking state of the vehicle during high speed driving is determined according to the set logic.
또한, 상기 E. C. U. (10)로부터 출력되는 제어 신호는 트랜지스터(TR1, TR2)를 통해 신호를 증폭하고 증폭된 신호는 각각의 릴레이(RY1, RY2)를 통해 솔레노이드 밸브(20)와 압축기(40)를 각각 제어할 수 있게 하되, 특히 개방되는 솔레노이드 밸브(20)는 고압 공기 저장 탱크(50)에 저장된 고압의 에어를 고압 공기 배출관(32)을 통해 차량의 앞범퍼(60)로부터 강하게 분사할 수 있게 하고, 압축기(40)는 급제동시 방출된 고압 공기 저장 탱크(50)의 에어를 일정 압력이 되는 고압의 상태까지 작동되어 에어를 고압의 상태로 재충전할 수 있게 한다.In addition, the control signal output from the ECU 10 amplifies the signal through the transistors TR1 and TR2, and the amplified signal operates the solenoid valve 20 and the compressor 40 through the respective relays RY1 and RY2. The solenoid valve 20, which can be controlled in each case, is particularly open so that the high pressure air stored in the high pressure air storage tank 50 can be strongly injected from the front bumper 60 of the vehicle through the high pressure air discharge pipe 32. In addition, the compressor 40 is operated to a state of high pressure such that the air of the high pressure air storage tank 50 released during rapid braking becomes a constant pressure, thereby recharging the air to a high pressure state.
따라서, 압력 센서(16)는 고압 저장 탱크내의 에어의 압력을 측정하여 E. C. U. (10)에 감지신호를 입력함으로서 E. C. U. (10)가 설정된 로직에 의해 공기의 압력이 일정 압력으로 유지될 때까지 압축기(40)를 작동하기 위한 제어 신호를 출력할 수 있게 구성한다.Accordingly, the pressure sensor 16 measures the pressure of the air in the high pressure storage tank and inputs a detection signal to the ECU 10 so that the compressor 10 maintains a constant pressure until the air pressure is maintained at a constant pressure by the logic set by the ECU 10. 40) to output a control signal for operating.
상기한 본 고안의 구성에 대한 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effect on the configuration of the present invention described above are as follows.
속도 센서(12)와 브레이크 페달의 포지션 센서(14)의 신호를 입력하는 E. C. U. (10)는 고속 주행중 차량이 급제동되는 상태를 판단하여 제어 신호를 출력하는 작용을 한다.E. C. U. 10, which inputs signals from the speed sensor 12 and the position sensor 14 of the brake pedal, determines a state in which the vehicle is suddenly braked during high speed driving and outputs a control signal.
또한, 상기 E. C. U. (10)로부터 판단된 신호에 따라 출력되는 제어 신호는 트랜지스터(TR1, TR2)를 통해 신호가 증폭되고 증폭된 신호를 접지하여 작동되는 각각의 릴레이(RY1, RY2)는 급제동시 고압의 에어를 차량의 앞범퍼(60)로부터 분사하기 위하여 솔레노이드 밸브(20)를 작동할 수 있게 하고, 고압의 에어가 분사된 후 고압 공기 저장 탱크(50)의 에어를 일정 압력까지 유지하기 위하여 압축기(40)를 작동할 수 있게 하는 작용을 한다.In addition, the control signal output according to the signal determined from the ECU 10 is amplified signal through the transistor (TR1, TR2) and each of the relays (RY1, RY2) operated by grounding the amplified signal is a high voltage during sudden braking To operate the solenoid valve 20 to inject the air from the front bumper 60 of the vehicle, and to maintain the air of the high pressure air storage tank 50 to a predetermined pressure after the high pressure air is injected. (40) acts to enable the operation.
특히, 상기 솔레노이드 밸브(20)는 고압 공기 저장 탱크(50)의 고압의 에어가 평시에는 고압의 상태로 보관될 수 있게 하는 작용을 하며 E. C. U. (10)로부터 출력되는 제어 신호에 의해 작동되는 릴레이1(RY1)에 의해 개폐 상태가 제어되어 고압의 에어를 고압 공기 배출관(32)을 통해 차량의 앞범퍼(60)로부터 강하게 분사/방출되게 하는 작용을 한다.In particular, the solenoid valve 20 acts to allow the high pressure air of the high pressure air storage tank 50 to be normally stored at a high pressure and is operated by a control signal output from the ECU 10. The opening / closing state is controlled by RY1 to strongly inject / eject the high pressure air from the front bumper 60 of the vehicle through the high pressure air discharge pipe 32.
따라서, 차량의 앞범퍼(60)로부터 강하게 분사되는 고압의 에어는 분사시 작용되는 반작용의 힘을 차체에 제공하여 제동되는 차량을 한층 더 제동하게 됨으로서 차량의 타이어가 밀릴 경우 차량에 제동력을 제공하는 작용을 한다.Therefore, the high pressure air injected strongly from the front bumper 60 of the vehicle provides the braking force to the vehicle body by providing a reaction force applied during the injection, thereby providing a braking force to the vehicle when the tire of the vehicle is pushed. It works.
이와 같이, 본 고안의 장치는 차량이 고속 주행중 차량이 급제동을 하게 되면 고압의 에어가 차량의 앞범퍼로부터 강하게 분사되어 강한 제동력에 의해 타이어가 밀릴 경우 제동력을 한층 증대하여 제동거리를 최대한으로 단축하게 됨으로서 차량이 추돌 및 추락되는 위험으로부터 최대한 보호될 수 있게 하는 효과를 발휘하게 된다.In this way, the device of the present invention, when the vehicle is braking while the vehicle is driving at high speed, high-pressure air is strongly injected from the front bumper of the vehicle, and when the tire is pushed by the strong braking force, the braking force is further increased to shorten the braking distance to the maximum. As a result, the vehicle can be maximally protected from the collision and the risk of falling.
