Measuring the weight of a vehicle in motion, with high accuracy, is an extremely difficult problem. Besides the desired vehicle weight, sensor data will include other extraneous inputs due to vehicle impact load and vibration etc. furthermore, measured signals are transient in nature and of very short duration. In this paper, we propose a weight measurement system (hardware configuration and analysis algorithms) employing a combination of system identification concepts and data classification by knowledge-based heuristic rules. The hardware consists of two scales in a series configuration. Weight measurements were done using a loaded truck (total weight 8 tons) at speeds ranging from 10-50 [km/h]. Based on data from over 200 test runs, our system can measure the truck weight within an error of less than 5% for the complete data set. Furthermore, the maximum average error of less than 2%.
