Description

자동차 쏠림방지조향장치Anti-Tip Steering Device

본 고안은 자동차 쏠림방지조향장치에 관한 것으로서, 더욱 상세히는 자동차의 조향시, 급격한 회전을 감지하여 조향을 수행함으로서 회전측으로의 차량의 쏠림을 방지하기 위한 것이다.The present invention relates to a vehicle anti-steering steering apparatus, and more particularly, to prevent the vehicle from tipping to the rotating side by performing steered steering by sensing a sudden rotation of the vehicle.

자동차의 운전중, 급격한 우회전 또는 좌회전의 조향을 수행하게 되면, 차량은 회전방향 반대방향으로 쏠림이 유발되고 이러한 쏠림은 운전자에게 자세를 변경하게 할 뿐만아니라 차량 자체의 조향성능을 성실하게 함으로서 후속적인 사고를 유발하는 요인이 된다.While driving a car, if a steered right turn or left turn is performed, the vehicle is caused to tilt in the opposite direction of rotation, and this tilt not only causes the driver to change his posture, but also makes the vehicle's own steering performance faithful. It is a factor that causes an accident.

이러한 문제로 인하여 운전자는 급격한 회전조향이후에 자신도 모르게 조향핸들을 좌우로 요동하여 차량의 조향력을 복원하려고 하지만 이는 숙련된 운전자가 아니면 행하기 어렵고 주행판단을 흐르게하여 숙련자가 하더라도 사고를 유발하게 될 우려가 있다.Because of this problem, the driver unintentionally swings the steering wheel to the left and right to restore the steering power of the vehicle without the driver's knowledge. There is concern.

본 고안에서는 상기한 종래 기술의 문제점을 감안하여, 운전자가 의식하지 아니하더라도 단위시간당, 소정이상의 회전각으로 조향을 수행하게 되면 자동적으로 좌우미세요동을 가능하게 하는 조향장치를 제공함으로서 상술하는 문제점을 해결하는 것을 목적으로 한다.In the present invention, in view of the above-mentioned problems of the prior art, even if the driver is not aware of the above-mentioned problems by providing a steering device that enables automatic left-right movement when steering is performed at a predetermined rotation angle per unit time. It aims to solve.

This is a control flow diagram illustrating the control of an anti-tip steering device.

제 1 도에 통상적인 조향장치가 도시되어 있다.A conventional steering device is shown in FIG.

스티어링튜브(1)의 내방에는 중앙에 피스톤(2)을 가지는 스티어링샤프트(3)가 관통되어 설치되고, 스티어링샤프트(3)는 중앙부에 고착된 피스톤(2)에 의하여 양분되는 작동유액의 좌우급속압력에 따라서 도면 좌우로 스티어링된다.The inner side of the steering tube (1) is installed through the steering shaft (3) having a piston (2) in the center, the steering shaft (3) is the left and right rapid speed of the working fluid divided by the piston (2) fixed to the center Steering left and right in accordance with the pressure.

상기하는 스티어링튜브(1)와 피스톤(2)이 구성하는 유체압력공간으로 유체를 급송하는 기구는 일측단에 부착된 스티어링실린더(4)이다.The mechanism for feeding fluid into the fluid pressure space constituted by the steering tube 1 and the piston 2 is a steering cylinder 4 attached to one end.

본 고안에서는 상기하는 일반적인 구성의 조향장치에 있어 좌우유체압조절기구(S)를 더 구비하는 것을 특징으로 한다.The present invention is characterized in that the steering device of the general configuration described above further comprises a left and right fluid pressure control mechanism (S).

상기의 좌우유체압조절기구(S)는 도시하는 바와 같이 ; 스티어링튜브(1)와 피스톤(2)이 구성하는 좌측유체공간(10)과 우측유체공간(20)과 각각 유체연결되는 유체관(11, 21)을 구비하며 이 유체관(11, 21)은 조절실린더(30)의 좌우측조절유체공간(31, 32)로 연결된다.The left and right fluid pressure control mechanism (S) as shown; And a fluid pipe (11, 21) in fluid connection with the left fluid space (10) and the right fluid space (20) constituted by the steering tube (1) and the piston (2), the fluid pipes (11, 21) It is connected to the left and right control fluid space (31, 32) of the control cylinder (30).

본고안에 사용되는 조절실린더(30)의 좌우측조절체공간(31, 32)은 도시하는 바와 같이, 관상튜브의 실린더바디(40) 내방의 양단에 형성된 실린더이며 중앙부에는 격벽(40')을 중심으로 좌우한쌍의 작동솔레노이드(41, 41')가 장착되며, 이 작동솔레노이드(41,41')의 플런저(42)는 스프링(43)에 의하여 탄발되면서 좌우로 유동가능하게 구성된다.The left and right control body spaces 31 and 32 of the control cylinder 30 used in this paper are cylinders formed at both ends of the inner side of the cylinder body 40 of the tubular tube and have a center portion 40 'at the center. A pair of left and right actuating solenoids 41 and 41 'are mounted, and the plunger 42 of the actuating solenoids 41 and 41' is elastically movable by the spring 43 and configured to be movable left and right.

따라서, 상기하는 구성으로서 실린더바디(40) 내방에서 작동솔레노이드(41, 41')의 어느 하나에 전기적인 신호가 인가되면 작동솔레노이드(41, 41')에 의하여 플런저(42)는 스프링(43)의 탄성력을 극복하면서 도면 좌우로 이동하게 되고 따라서 좌우의 좌우측조절체공간(31, 32)중, 하나는 압축되고 하나는 팽창되게 된다.Therefore, as described above, when an electrical signal is applied to any one of the operating solenoids 41 and 41 'inside the cylinder body 40, the plunger 42 is connected to the spring 43 by the operating solenoids 41 and 41'. Overcoming the elastic force of the figure is moved to the left and right in the drawing, so that one of the left and right control body spaces 31 and 32, one is compressed and one is expanded.

상기하는 작동솔레노이드(41, 41')에 전기적인 신호를 인가하는 것은 차량의 장착되는 통상적인 ECU(50)에 입력되는 프로그램에 의하여 수행되는 것이 좋고 이러한 ECU에 입력된 프로그램은 역시 ECU(50)에 입력되는 차속센서(60)와의 협동으로 하기와 같이 작동하도록 프로그래밍된다.The application of the electrical signal to the above-described operating solenoids 41 and 41 'is preferably performed by a program input to the conventional ECU 50 mounted on the vehicle, and the program input to such ECU is also the ECU 50. It is programmed to work as follows in cooperation with the vehicle speed sensor 60 that is input to.

제 2 도에 도시되는 엔코더는 차량의 핸들에 취부되거나 조향동력축 중간에 설치되는 감지디스크(60)로서 회전축(61)과 함께 등각도로 회전하면서, 그 표면에는 다수개의 원호상으로 배열된 감지슬리트(62)를 가지며 일단에는 송수광센서(63)를 장착하여 엔코딩을 수행한다.The encoder shown in FIG. 2 is a sensing disk 60 mounted on a steering wheel of a vehicle or installed in the middle of a steering power shaft, and is rotated at an isometric angle with the rotating shaft 61, and the sensing slits arranged in a plurality of arcs on the surface thereof. It has a track 62 and one end is equipped with a light transmitting and receiving sensor 63 to perform the encoding.

상기에는 엔코딩 수단으로서 조향핸들의 시간당회전각을 검출하여 상기하는 ECU(50)로 보내게 된다.In the above, as the encoding means, the steering wheel's time of rotation angle is detected and sent to the ECU 50.

ECU(50)에서는 상기의 엔코딩수단으로부터의 전기적인 신호를 입력받아(100), 시간당 회전각도, 즉 단위시간당 조향핸들의 회전각을 계산(101)하여, 일정한 차속이상에서 소정의 설정치(A)이상의 값인가를 판단(102)하여 그 이상이면(Y), 급격한 회전임을 감지하여 작동솔레노이드(41, 41')에 전기적인 펄스신호를 유발하게하여(103), 작동솔레노이드(41, 41')가 좌우로 이동하게 함(105)으로서, 좌우유체압조절기구(S)의 좌우측조절유체공간(31, 32)의 유체압을 일정한 압력으로 요동하게 하여 이 요동하는 유체압은 다시, 스티어링튜브(1)와 피스톤(2)이 구성하는 좌측유체공간(10)과 우측유체공간(20)을 연결하는 유체관(11, 21)을 따라서 좌측유체공간(10)과 우측유체공간(20)으로 전달됨으로서 스티어링샤프트(3)는 좌우로 미소하게 유동하여 운전자가 수동조작으로서 요동을 수행하여 안정화하는 것과 동일한 효과를 가지게 된다.The ECU 50 receives the electrical signal from the encoding means (100), calculates the rotation angle per hour, that is, the rotation angle of the steering wheel per unit time (101), and sets a predetermined value (A) at a constant vehicle speed or more. Determining whether the value is ideal 102 or more (Y), by detecting a sudden rotation to cause an electrical pulse signal to the operating solenoid (41, 41 ') (103), the operating solenoid (41, 41') By moving the left and right 105, the fluid pressure in the left and right control fluid spaces 31 and 32 of the left and right fluid pressure regulating mechanism S is made to oscillate at a constant pressure so that the oscillating fluid pressure is again controlled by the steering tube ( 1) is transferred to the left fluid space 10 and the right fluid space 20 along the fluid pipe (11, 21) connecting the left fluid space 10 and the right fluid space 20 constituted by the piston (2). As a result, the steering shaft 3 flows slightly from side to side, and the driver A it will have the same effect as stabilized by performing.

만일, 설정된 값(A)이하이면 정상적인 조향작동을 수행하도록 원래의 루틴으로 복귀한다.If it is less than or equal to the set value A, it returns to the original routine to perform normal steering operation.

이상과 같은 본고안의 자동차 쏠림방지조향장치는, 운전자의 별도의 조작없이도 급격한 회전임을 일정한 차속이상의 경우에, 자동적으로 감지하여 일정 이상의 회전각을 가지면 조향장치의 좌우스티어링압력을 변동시킴으로서 안정화를 도모하게하여 후속적인 운전을 안전하게 수행함으로서 각종의 교통사고를 미연에 방지하는 유용성을 가진다.As described above, the vehicle anti-tip steering device automatically detects a sudden rotation without a driver's separate operation at a certain vehicle speed, and stabilizes it by changing the left and right steering pressures of the steering device when the vehicle has a certain rotation angle. It is useful to prevent various traffic accidents by safely performing subsequent driving.
