본 발명은 자동차의 서스펜션에 있어서, 차량으 급제동시나 차량의 급회전시에 발생하는 관성력에 서스펜션을 효과적으로 제어하여, 탑승자의 승차감, 자동차의 자세 및 조정 안정성을 향상한 자동차의 액티브서스펜션에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an active suspension of a vehicle in which the suspension is effectively controlled by the inertia force generated during braking of the vehicle or during rapid rotation of the vehicle, thereby improving the ride comfort of the occupant, the attitude of the vehicle, and the adjustment stability.
일반적으로 액티브 서스펜션은 차량의 상태에 따라 스스로 자유롭게 스트로크를 제어하기 때문에 차량주행시 평편한 느낌을 주는 부드러운 승차감과 자동차의 운동, 즉 회전시에 차량운동 특성을 최적화해주며, 도로면 및 차속에 적합한 최적의 차고를 제어한다.In general, the active suspension controls the stroke freely according to the condition of the vehicle, thereby optimizing the smooth ride feeling that gives a flat feeling when driving the vehicle and the characteristics of the movement of the vehicle, that is, the vehicle movement when turning, and is optimized for the road surface and the vehicle speed. Control the garage.
그러나, 상기 종래의 액티브 서스펜션은 차량의 순간적인 급제동시에나, 차량의 급회전시에 서스펜션을 제어하기 위한 차속이나 조향각등의 순간적인 제어가 되지 않기 때문에 신속한 응답성이 떨어진다는 결점이 있었다.However, the conventional active suspension has a drawback that rapid response is inferior because instantaneous braking of the vehicle or instantaneous rotation of the vehicle does not provide instantaneous control such as vehicle speed or steering angle for controlling the suspension.
본 발명의 목적은 상기와 같은 종래의 결점을 해결하기 위한 것으로, 차량의 순간적인 변화와 변화방향을 감지할 수 있는 가속도 센서를 이용하여 차량의 급제동시나 급회전시에 각 방향의 서스펜션을 신속하게 제어함으로서, 신속한 응답성을 제공하여 탑승자의 승차감, 자동차의 자세 및 조정 안정성을 향상한 자동차의 액티브서스펜션을 제공하는 데 있다.SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned shortcomings, and to quickly control the suspension in each direction during rapid braking or rapid rotation of the vehicle by using an acceleration sensor capable of detecting the momentary change and the change direction of the vehicle. By providing a quick response, it is to provide an active suspension of the vehicle that improves the ride comfort of the occupant, the attitude and adjustment stability of the vehicle.
이하 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.
본 발명 장치는 제1도에 나타낸 바와같이, 차량의 속도를 감지하는 차속센서(11)와, 차량의 순간적인 변화와 변화방향을 감지할 수 있는 가속도센서(12)와, 차량의 조향각을 감지하는 조향각센서(13)로 이루어진 차량상태 감지부(10)와 ; 상기 차량상태 감지부(10)의 감지된 차량의 상태에 따라 서스펜션을 제어하는 서스펜션 제어부(20)와 ; 차량의구동바퀴의 서스펜션을 조절하는 서스펜션구동부(30)로 구성함을 그 기술적 구성상의 특징으로 한다.The apparatus of the present invention, as shown in Figure 1, the vehicle speed sensor 11 for detecting the speed of the vehicle, the acceleration sensor 12 for detecting the instantaneous change and the change direction of the vehicle, and detects the steering angle of the vehicle A vehicle state sensing unit 10 formed of a steering angle sensor 13 to be provided; A suspension control unit 20 for controlling the suspension according to the detected state of the vehicle of the vehicle state detecting unit 10; The configuration of the suspension driving unit 30 for adjusting the suspension of the driving wheel of the vehicle is characterized by its technical configuration.
상기 가속도센서(13)는 제2도에 나타낸 바와같이, 밑면에는 수광소자(122)가 형성된 수광판(121)의 네 변에 수직으로 벽면이 형성되고, 상기 수광판(121)에 대칭된 상판에는 발광장치(123)가 형성되어, 상기 발광장치(123)에서 생성된 빛은 광섬유케이블(124)과 차량의 운동상태를 감지하기 위해 자유회동이 가능한 베어링(125)과, 상기 베어링(125)에 접속된 지지대(126) 및 추(127)를 통하여 수광판(121)을 비추게 형성되고, 상기 수광판(121)에 연상장치(128)가 접속되어, 상기 수광판(121)에 비친 빛의 변화로 차량의 순간적인 변화와 변화방향을 감지할 수 있다.As shown in FIG. 2, the accelerometer 13 has a top surface perpendicular to four sides of the light receiving plate 121 on which the light receiving element 122 is formed, and is symmetrical to the light receiving plate 121. The light emitting device 123 is formed in the light, and the light generated by the light emitting device 123 is freely rotatable for the movement of the optical fiber cable 124 and the vehicle 125, and the bearing 125. The light receiving plate 121 is formed to shine through the support 126 and the weight 127 connected to the light receiving device 121. An associating device 128 is connected to the light receiving plate 121, and the light reflected from the light receiving plate 121 is reflected. With the change of, the momentary change of the vehicle and the direction of change can be detected
이러한 본 발명 장치의 작용 및 효과를 제2도와 제3도를 참조하여 상세히 설명하면 다음과 같다.The operation and effects of the present invention will be described in detail with reference to FIGS. 2 and 3 as follows.
먼저, 제2도에 나타낸 것은 가속도센서(12)의 구조도로서, 차량이 운행중이 아닌 경우에는 A위치의 수광판(121)의 수광소자(122)가 발광장치(123)으로 부터 생성된 빛을 받게되면, 연산장치(128)는 현재의 차량상태를 정지상태로 판단하게 된다.First, FIG. 2 is a structural diagram of the acceleration sensor 12. When the vehicle is not running, the light receiving element 122 of the light receiving plate 121 at the A position receives the light generated from the light emitting device 123. When received, the operation unit 128 determines the current vehicle state as the stationary state.
차량이 순간적으로 움직이게 되면, 추(127)의 움직임으로 빛의 방향도 움직이게 된다.When the vehicle moves momentarily, the direction of the light also moves by the movement of the weight 127.
이러한 변화는 추(127)가 지지대(126)를 통하여 자유회동이 가능한 베어링(125)로 고정되기 때문에 차량의 운동방향대로 움직이는데, 예를 들어 빛이 수광판(121)의 B위치를 비추게 되면, 처음의 A위치와 B위치와의 거리로서 차량의 순간적인 속도변화 및 변화방향을 감지하게 되는 것이다.This change is moved in the direction of movement of the vehicle because the weight 127 is fixed to the bearing 125, which can be freely rotated through the support 126, for example, when light shines on the B position of the light receiving plate 121 In other words, the distance between the first A position and the B position detects the instantaneous speed change and the change direction of the vehicle.
제3도를 참조하여 본 발명의 동작을 설명하면, 차량상태감지부(10)에서 차량의 차속, 가속도 및 조향각을 감지하여(S1), 노면에 굴곡과 경사가 없으면(S2), 가속도센서(12)와 조향각센서(13)의 신호를 재차 감지한다(S4).Referring to Figure 3 describes the operation of the present invention, the vehicle state detection unit 10 detects the vehicle speed, acceleration and steering angle of the vehicle (S1), if there is no bend and slope on the road surface (S2), acceleration sensor ( 12) and the steering angle sensor 13 again detects the signal (S4).
이때 차량의 속도가 20 Km/h 이상이면(S5), 상기 가속도센서(12)에서 차량의 순간적인 속도변화 및 변화방향과 조향각센서(13)의 조향각을 종합하여 서스펜션구동부(30)를 제어한다.At this time, when the speed of the vehicle is 20 Km / h or more (S5), the acceleration sensor 12 controls the suspension driving unit 30 by combining the momentary speed change and the change direction of the vehicle and the steering angle of the steering angle sensor 13. .
한편, 노면에 굴곡과 경사각이 있으면(S2), 현 노면상태에 따라 서스펜션구동부(30)를 기본자료값으로 설정한다.On the other hand, if there is a bend and inclination angle on the road surface (S2), according to the current road surface state, the suspension driving unit 30 is set as the basic data value.
그리고, 차량의 속도가 20 Km/h 이하이면(S5), 도로의 변화가 크더라도 관성력이 차량에 미치는 영향이 적으므로 연비향상을 위하여, 상기 기본자료값으로 제어한다.And, if the speed of the vehicle is 20 Km / h or less (S5), even if the change of the road is large, the inertial force has little effect on the vehicle, so as to improve the fuel economy, the basic data value is controlled.
이상에서 살펴본 바와 같이, 본 발명장치는 차량의 순간적인 급제동시나 급회전시에 신속한 응답성으로 서스펜션을 제어하여 승차감 및 자동차의 자세, 조정 안정성을 향상시킨다.As described above, the present invention improves the riding comfort, the attitude of the vehicle, and the adjustment stability by controlling the suspension with rapid response during instant braking or rapid turning of the vehicle.
