Description
본 발명은 차량의 선회시 토인 제어장치로, 더욱 상세하게는 차량 선회시에 작용하는 횡력에 의하여 후륜을 토인 제어하여 후륜의 코너링력을 크게 하여 고속 선회시에 주행 안정성을 확보함은 물론 제동시에 토인 제어하여 제동 안정성을 갖추게 한 차량의 선회시 토인 제어장치에 관한 것이다.The present invention is a toe control device for turning a vehicle, and more specifically, toe-control the rear wheel by the lateral force acting during the vehicle turning to increase the cornering force of the rear wheel to secure driving stability during high-speed turning as well as during braking. The present invention relates to a toe control device during turning of a vehicle in which toe control is performed to provide braking stability.
자동차에 있어서의 현가장치는 차체와 차륜사이에 존재하면서 이 2개 강체를 하나 혹은 다수의 컨트롤 아암으로 연결하여 상하 방향으로는 스프링과 쇽업소오버에 의하여 지지되고, 기타방향으로 높은 강성과 유연성을 적절히 조화시킴으로써, 차체와 차륜사이의 상대운동을 기계적으로 적절히 조화시켜 주행중 노면으로부터 받는 진동과 충격을 흡수하여 승차감과 선회안정성을 향상시키는 장치이다.Suspensions in automobiles exist between the body and the wheels and are connected by one or more control arms, supported by springs and shock absorbers in the vertical direction, and high rigidity and flexibility in the other directions. By appropriately harmonizing, the relative motion between the vehicle body and the wheels is mechanically harmonized to absorb vibrations and shocks received from the road surface while driving to improve ride comfort and turning stability.
이러한 현가장치는 노면으로부터의 입력에 대한 여러부문의 성능을 만족시키기 위하여 다음의 3가지 조건이 요구되고 있다.In order to satisfy the performance of various sectors for the input from the road surface, the following three conditions are required.
첫째, 조정 안정성을 위하여 타이어는 노면에 대하여 이상적인 자세를 유지케하여 노면에 대한 그립력을 극대화하고, 차체는 나름대로 최상의 자세를 유지하여 목적하는 차량 운동상태를 가능케 하여야 하며, 특히 어떠한 상태에서도 항상 다음 동작을 얻을 수 있는 순간력을 지님과 동시에 운전자의 의도하는 방향 및 순간외에는 외부 입력에 의한 어떠한 거동도 허용하면 안된다.First, the tire should maintain the ideal posture on the road surface to maximize the grip force, and the body should maintain the best posture in order to enable the desired vehicle movement state. At the same time, the driver should not allow any action by external inputs other than the driver's intended direction and moment.
둘째, 안락감을 위하여 어떠한 충격도 흡수할 수 있도록 하여 차내에 있는 탑승자들로 하여금 불쾌감을 느끼지 못하도록 하여야 한다.Second, it should be possible to absorb any shock for comfort so that passengers in the car do not feel uncomfortable.
셋째, 충돌시 이의 충돌에너지의 흡수에 기여토록 하여 충돌 안정성을 증대시킬 수 있도록 하여야 한다.Third, the collision stability should be contributed to the absorption of the collision energy of the collision.
이에 따라 제안된 액티브 지오메트리 컨트롤 서스펜션은 어떤 조건에서도 일정하다고 가정된 차속과 조향 각도센서신호의 입력을 받아서 선회시 토인을 제어하는 기술로 알려져 있다.Accordingly, the proposed active geometry control suspension is known as a technique for controlling toe-in when turning by receiving input of vehicle speed and steering angle sensor signals assumed to be constant under any conditions.
그러나 첫째, 선회시에 내/외륜의 속도가 일정하다고 보았다. 그리고 토인제어의 크기를 결정하기 위해서 조향각도센서신호와 차속센서의 입력을 통해서 횡가속도의 크기를 계산하였는데 이 계산식은 차량의 정확한 거동을 표현할 수 없다는 문제점이 있다.First, however, the speed of the inner / outer ring was constant at the time of turning. In order to determine the magnitude of the toe control, the magnitude of the lateral acceleration was calculated through the input of the steering angle sensor signal and the vehicle speed sensor, which has a problem in that it cannot express the exact behavior of the vehicle.
둘째, 종래의 기술에서는 제동시에 토인 제어를 포함하고 있지 않고 있다.Second, the prior art does not include toe-in control during braking.
셋째, 선회시 발생하는 횡력의 평행한 방향으로 모터를 구동해야 하므로 큰용량의 모터가 필요한 문제점이 있다.Third, since the motor must be driven in a parallel direction of the lateral force generated when turning, there is a problem that a large capacity motor is required.
상기한 바와 같은 종래기술의 문제점을 해소하기 위하여 제안된 본 발명의 목적은 차량의 선회시에 내/외륜의 속도차가 발생한다는 것에 착안하여 간단하면서도 정확하게 토인제어의 크기를 결정하여 선회 안정성을 높힘과 아울러, 제동시에 차속의 감속율을 계산하여 토인제어를 하므로써 제동 안정성을 향상시키게 되는 차량의 선회시 토인 제어장치를 제공하는데 있다.The object of the present invention proposed to solve the problems of the prior art as described above is to determine the size of the toe control simply and accurately in order to increase the turning stability by focusing on the fact that the speed difference between the inner and outer rings occurs during the turning of the vehicle. In addition, the present invention provides a toe control device during turning of a vehicle which improves braking stability by calculating a deceleration rate of the vehicle speed during braking to perform toe-in control.
이를 실현하기 위한 구성은 차량의 선회시 토인 제어장치에 있어서,각 차륜의 휠속도를 감지하게 설치된 휠 속도센서와,상기 휠 속도센서로부터 인가된 전기적인 신호를 기 설정된 정보에 의해 휠속도를 인지하고 내/외 차륜의 휠 속도 차이를 판단하여 상기 휠 속도 차이에 비례하는 토인제어신호를 출력하는 전자제어장치와,The configuration for realizing this is in a toe-in control device when the vehicle is turning, the wheel speed sensor is installed to detect the wheel speed of each wheel, and the wheel speed is recognized by the predetermined information from the electric signal applied from the wheel speed sensor And the electronic control device for outputting a toe control signal proportional to the wheel speed difference by judging the wheel speed difference of the inside / outside wheel,
상기 전자제어장치의 토인제어신호에 의해 로워아암을 전,후진 구동시켜 후륜의 토인을 제어하게 설치한 모터를 포함한 구성으로 이루어지는 차량의 선회시 토인 제어장치를 제공하는데 있다.한편, 이를 실현하기 위한 다른 견지에 따른 구성은,자동차의 선회시 각 차륜의 휠 속도센서에 의해 휠속도와 상기 휠 속도의 급감속 여부를 감지하는 과정과;상기 감지된 휠 속도에 의해 내/외 차륜의 휠 속도 차이를 판단하여 상기 휠 속도 차이에 비례하는 토인제어신호를 출력하고 상기 휠속도 급감속/저감속에 따라 토인을 증가/감소시키는 토인제어신호를 출력하는 과정과;로워아암이 상기 토인제어신호에 따른 토인 각을 형성하도록 모터를 전,후진 구동시켜 제어하는 과정으로 이루어지는 차량의 선회시 토인제어장치의 제어방법을 제공하는데 있다.To provide a toe control device for turning a vehicle comprising a motor which is installed by the toe control signal of the electronic control device to drive the lower arm forward and backward to control the toe of the rear wheel.

이하, 본 발명의 바람직한 일 실시예를 첨부한 도면에 의하여 더욱 상세하게 설명한다. Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in more detail.
도1은 본 발명에 따른 선회시 토인 제어장치의 구성을 도시한 블럭도이고, 도2는 본 발명에 따른 선회시 토인 제어장치를 도시한 도면이다.1 is a block diagram showing the configuration of the toe control device when turning in accordance with the present invention, Figure 2 is a view showing a toe control device when turning in accordance with the present invention.
그리고 도3은 본 발명에 따른 선회시 휠속도센서에 의해 내/외륜 바퀴의 속도차 검출을 도시한 도면이다.3 is a diagram illustrating a speed difference detection of inner / outer wheels by a wheel speed sensor when turning in accordance with the present invention.
차량의 선회시 토인 제어장치(2)는 각 차륜(4)의 휠속도를 감지하게 설치된 휠속도 센서(6)와, 상기 휠속도 센서(6)로부터 인가된 전기적인 신호를 기 설정된 정보에 의해 바퀴차속을 인지하여 판단 제어하는 전자제어장치(8)와, 상기 전자제어장치(8)의 신호에 의해 로워아암(10)을 전,후진 구동시켜 후륜의 토인을 제어하게 설치한 모터(12)를 포함한 구성으로 이루어지고 있다.When turning the vehicle, the toe control device 2 uses a wheel speed sensor 6 installed to detect wheel speed of each wheel 4 and an electric signal applied from the wheel speed sensor 6 based on preset information. An electronic controller 8 for recognizing and controlling wheel speed and a motor 12 for driving the lower arm 10 forward and backward by controlling the signal of the electronic controller 8 to control the toe of the rear wheel. Consists of a configuration including.
상기한 전자제어장치(8)는 차량 선회시에 내/외륜 바퀴의 속도를 각 차륜(4)에 설치된 휠 속도센서(6)를 통해 비교한다.The electronic controller 8 compares the speed of the inner / outer wheels with the wheel speed sensor 6 provided in each wheel 4 when the vehicle is turning.
V = rw (V=바퀴차속, r=회전반경, w=각속도)V = rw (V = wheel speed, r = radius of rotation, w = angular speed)
각속도 w = 일정, 내/외륜의 속도차이는 도3에 나타난 바와 같이 약 18 %의 내/외륜의 속도차가 생기게 되는데, 이는 단, 회전 반경이 크면 클수록 그 차이가 줄어들며, 이 때는 토인 제어가 필요하지 않는 조건이 되지만, 그러나 회전반경이 작을수록 내/외륜의 속도차이는 상대적으로 증가하게 되어 필요하게 된 토인 제어에 의해 내/외륜의 속도를 검출 및 비교하여 토인의 양을 조절하게 된다.Angular velocity w = constant, speed difference between inner and outer rings is about 18% speed difference between inner and outer rings as shown in Fig. 3, except that the larger the turning radius, the smaller the difference, and this requires toe-in control. However, as the radius of rotation becomes smaller, the speed difference between the inner and outer rings increases relatively, and the toe control required to detect and compare the speeds of the inner and outer rings to adjust the amount of toe-in.
삭제delete
즉, 속도차이가 많이 나는 경우는 회전 반경이 작은 것으로 판단되므로 토인 제어를 크게 하여 횡력을 크게 증대 시켜야 하는 경우이다.In other words, when the speed difference is large, the radius of rotation is judged to be small. Therefore, it is necessary to increase the lateral force by increasing the toe control.
또, 차량의 급제동시 급정지한다면 차속이 점진적으로 줄어드는 것을 바퀴의 휠속도 센서(6)를 이용해서 전자제어장치(8)에 의해 측정이 가능하다.In addition, if the vehicle suddenly stops during sudden braking, the electronic speed controller 6 can measure that the vehicle speed gradually decreases using the wheel speed sensor 6 of the wheel.
즉, 급제동 되고 있다는 신호는 휠속도 센서(6)를 통해서 간단하게 전자제어장치(8)가 검출할 수 있고 속도가 급격히 감소하게 된다면 토인 제어의 크기를 많이 빠르게 작동시키고 속도의 감소가 적을 경우에는 토인 제어의 크기를 작게 하고 서서히 작동시킨다.That is, a signal that is suddenly braked can be easily detected by the electronic control device 8 through the wheel speed sensor 6, and if the speed decreases rapidly, the size of the toe-in control is operated rapidly and if the speed decrease is small. Reduce the size of the toe-in control and run it slowly.
상기한 로워아암(10)의 마운팅 위치에 전기 모터(12)를 장착해서 화살표 방향으로 이동시키면 후륜이 토인 방향으로 이동하게 되어서 선회시에 선회 안정성을 확보하고 제동시에는 안정성을 향상시킬 수 있다.When the electric motor 12 is mounted in the mounting position of the lower arm 10 and moved in the direction of the arrow, the rear wheel moves in the toe direction, thereby ensuring turning stability at the time of turning and improving stability at the time of braking.
상기한 본 발명은 첫째, 스티어링 휠속도센서와 차속의 함수를 통해서 복잡하게 계산되는 횡가속도를 이용하므로 정확한 차체의 상황을 계산해내기 어려울 뿐만 아니라 함수에 의한 값은 많은 오차를 포함하고 있어 차량이 처해 있는 상황을 정확하게 검출해 낼 수 없는 종래의 한계를 차량이 진행하는 동안에 바퀴의 중앙에 부착되어 있는 휠속도센서를 이용해서 직접 검출되는 내/외륜의 차속을 서로 비교함으로써 차량이 처해있는 상황을 간단하면서도 정확하고 정밀하게 검출해 낼 수 있는 효과를 구현할 수 있게 된다. First, the present invention uses the lateral acceleration, which is complicatedly calculated through the function of the steering wheel speed sensor and the vehicle speed, so that it is difficult to calculate the exact situation of the vehicle body, and the value of the function includes many errors. While the vehicle is progressing against the conventional limitations that cannot accurately detect the current situation, the vehicle speed is easily compared by using the wheel speed sensor attached to the center of the wheel. It is possible to realize an effect that can be detected accurately and precisely.
둘째, 차량이 직진하다가 정지하는 동안에는 작동하지 않도록 되어 있어 제동시에 제동 안정성을 보장 받기가 어려운 종래의 미비점을 차량이 감속하는 경우나 급제동시에 휠속도를 검출하고 계산하여 후륜의 토인 제어를 함으로써 제동 안정성을 보장 받게 되는 효과를 도모하게 된다. 즉, 제동시에 후륜이 토인으로 되면 횡력을 생성하므로 제동 안정성이 향상되게 된다.Second, braking stability is achieved by controlling the rear wheel toe-in by detecting and calculating the wheel speed when the vehicle is decelerating in the conventional weak point, which is difficult to guarantee braking stability during braking because it is not operated while the vehicle is going straight and stopped. The effect will be guaranteed. That is, when the rear wheel is toin during braking, the lateral force is generated, thereby improving the braking stability.
삭제delete
셋째, 차량의 횡력과 평행한 방향으로 연결된 어시스트 링크(Assist Link)에 전기 모터등이 연결 및 구동되어 큰 횡력에 대해서는 작동이 불가능하다는 종래 단점을 차량 선회시 발생하는 횡력과 수직 방향으로 로워 암에 연결되어 모터에 힘을 가할 수 있으므로 정확한 동작을 기대할 수 있게 되어 걸리는 부하에 수직한 방향으로 힘을 가하면 일은 영(zero)이 되는 결과의 효과를 가지게 된다.Third, the conventional disadvantage that an electric motor is connected to and driven by an assist link connected in a direction parallel to the lateral force of the vehicle is impossible to operate for a large lateral force. Because it can be connected to force the motor, accurate operation can be expected, and if the force is applied in a direction perpendicular to the load applied, the work has the effect of being zero.
또, ABS시스템에 장착된 휠속도 센서를 이용해서 내/외륜의 회전속도를 비교하여 차량이 처해있는 상황을 간단하면서도 정확하게 파악할 수 있고 제동 시에도 차량의 휠속도를 검출하여 토인 제어를 함으로써 제동 안정성을 보장 받을 수 있게 된다. In addition, by using the wheel speed sensor installed in the ABS system, the rotational speed of the inner / outer wheels can be compared to easily and accurately understand the situation of the vehicle. Can be guaranteed.
그리고 선회시에 발생하는 횡력에 수직한 방향으로 힘을 가할 수 있으므로 작은 전기 모터 사용이 가능하므로 패키지 구성이 용이한 효과가 있다.In addition, since the force can be applied in a direction perpendicular to the lateral force generated during the turning, a small electric motor can be used, and thus the package configuration is easy.
