Abstract
The mechanism between the automotive load and tire pressure is studied. By measuring the changes of tire pressure of the vehicle, the automotive load can be acquired indirectly. The model of the automotive load and force are analyzed, the effectiveness and practicality of the model are verified by the measurement experiments and error analysis. A novel and portable digital weighing instrument of vehicle load is designed based on the proposed measuring method. This apparatus is mainly composited of a pressure transmitter and a portable display terminal. The tests illustrate that this weighing apparatus feature in higher accuracy, low cost, and small size. It can be applied to the car-load measurement of vehicles in various types of tire.
