Abstract: front page image
(EN)The present invention provides a load measuring device and method capable of measuring, in real time, the load of a vehicle having a suspension with two-stage springs. The invention allows: sensors to be installed in both main springs and auxiliary springs of the suspension which has two-stages; and the weight, which is applied to the vehicle, to be measured by using measurement values of the sensors installed in the main springs and measurement values of the sensors installed in the auxiliary springs, wherein the measurement values are changed as the load is applied to the vehicle. Particularly, the invention adopts; a load measuring method using sensor values of the main springs or sensor values of the auxiliary springs in each load section of the vehicle; or a method for measuring the load that is applied to the vehicle by adding up the sensor measurement values of the main springs and the sensor measurement values of the auxiliary springs such that a mathematical formula capable of changing the added measurement values into the load is modeled, thereby calculating the applied load in real time by using the measurement values of the sensors, which are changed in real time according to the load that is applied to the vehicle, and outputting the calculated load to a user. Thus, even for conventional vehicles having a suspension with two-stage springs, to which the method for measuring the load of the vehicle in real time is difficult to apply, the invention can measure the exact load of the vehicle in real time, thereby effectively preventing an overload.
(FR)La présente invention se rapporte à un dispositif de mesure de charge et à un procédé capable de mesurer, en temps réel, la charge d'un véhicule qui présente une suspension avec des ressorts à deux étages. L'invention permet : d'installer des capteurs dans les ressorts principaux et dans les ressorts auxiliaires de la suspension qui présente deux étapes ; et de mesurer le poids qui est appliqué au véhicule, en utilisant les valeurs de mesure des capteurs installés dans les ressorts principaux et les valeurs de mesure des capteurs installés dans les ressorts auxiliaires, les valeurs de mesure étant modifiées lorsque la charge est appliquée au véhicule. En particulier, l'invention adopte ; un procédé de mesure de charge qui utilise les valeurs de capteur des ressorts principaux ou les valeurs de capteur des ressorts auxiliaires dans chaque section de charge du véhicule ; ou un procédé destiné à mesurer la charge qui est appliquée au véhicule en ajoutant les valeurs de mesures de capteur des ressorts principaux et les valeurs de mesures de capteur des ressorts auxiliaires de telle sorte qu'une formule mathématique capable de modifier les valeurs de mesure ajoutées dans la charge soit modélisée, en calculant de ce fait la charge appliquée en temps réel en utilisant les valeurs de mesure des capteurs, qui sont modifiées en temps réel selon la charge qui est appliquée au véhicule, et en délivrant en sortie la charge calculée à un utilisateur. Ainsi, même pour les véhicules conventionnels qui présentent une suspension avec des ressorts à deux étages, auxquels il est difficile d'appliquer le procédé destiné à mesurer la charge du véhicule en temps réel, l'invention permet de mesurer la charge exacte du véhicule en temps réel, en empêchant de ce fait de manière efficace une surcharge.
(KO)본 발명은 2단 스프링으로 구성된 현가장치를 구비하는 차량의 하중을 실시간으로 측정할 수 있는 하중 측장 장치 및 방법을 개시한다. 본 발명은 2단 스프링으로 구성된 현가장치의 주 스프링과 보조 스프링에 각각 센서를 설치하고, 차량에 하중이 인가됨에 따라서 변화되는 주 스프링에 설치된 센서의 측정값과 보조 스프링에 설치된 센서의 측정값을 이용하여 차량에 인가된 하중을 측정한다. 특히, 본 발명은 차량의 하중 구간별로 주 스프링의 센서값을 이용하거나 보조 스프링의 센서값을 이용하는 하중 측정 방식을 채택하거나, 주 스프링의 센서 측정값과 보조 스프링의 센서 측정값을 합산하여, 합산된 측정값을 하중으로 환산할 수 있는 수학식을 모델링하여, 차량에 인가되는 하중을 측정하는 방식을 채택하여, 차량에 인가되는 하중에 따라서 실시간으로 변화하는 센서들의 측정값을 이용하여 실시간으로 인가된 하중을 계산하여 사용자에게 출력할 수 있으므로, 종래의 실시간 차량의 하중을 측정하는 방법이 적용되기 어려운 2단 스프링으로 구성된 현가장치가 설치된 차량에 대해서도 실시간으로 정확한 차량의 하중을 측정할 수 있어 효과적으로 과적을 방지할 수 있다.
