Accuracy examination of an estimation method of axle weights for in-motion vehicles by using miniature experimental models

摘要

Axle weighing system measures axle weights of in-motion vehicles. A method have been studied for estimating axle weights by processing the weight signal from the axle weighing system to improve the accuracy. The method has been applied to in-motion vehicles at the velocity of less than 15 km/h and axle weights have been obtained in high accuracy. However, the examination of the accuracy of estimated axle weights of in-motion vehicles with higher velocity has not yet completed. To examine and improve the accuracy of the estimated axle weight, a miniature instrumented vehicle and a miniature weighbridge have been developed. This paper presents the examination of the accuracy of the estimation method by using the miniature experimental models.
