Study of Vehicle Load Detection Methods and its Load Measurement Model

According to the analysis and comparison among those existed ways of vehicle overloading detection,this paper presents an overloading control way based on a relationship model between leaf spring deformation and vehicle's load.Through the mathematical models and a parameter estimation algorithm,the vehicle loading can be estimated to realize whether the vehicle is overloading.Finally,the model and parameter estimation algorithm are simulated by matlab.The results show vehicle load can be objectively estimated by the model identified with a algorithm of parameter estimation.
