Abstract: A method and system for measuring vertical wheel impact force in real-time based on tire pressure monitoring is provided by the present invention. The system mainly includes the four modules, namely a tire pressure derotation preprocessing, a tire pressure-wheel force system identification, a calibration method, and an integrated device for tire pressure-wheel force measurement. The method uses the integrated device to collect tire pressure data in real-time. The corresponding vertical wheel impact force is obtained through the derotation preprocessing and the tire pressure-wheel force system identification, and is calibrated according to the calibration method. The present invention provides an efficient, accurate, and highly adaptable wheel force measurement solution in the theoretical aspect and device aspect, which meets the requirements for the quick evaluation of the bridge health condition. Also, the present invention has a great potential in the fields such as road safety diagnosis, automobile performance related design, etc.
