초록
The need for research on a sensor system that can monitor the dynamic load of a commercial vehicle in real-time is emerging because the development of autonomous vehicles is actively progressing worldwide. In this study, dynamic load measuing system of commercial vehicles was developed using the MEMs inclinometer attached to the leaf spring suspension. Test vehicle’s driving test was accomplished by changing speed and payload weight in several stages. Using the dynamic load measurement system, it was possible to check the weight shift and the change of stopping distance. When a driving speed increases from 30km/h to 80 km/h, the stopping distance increases from about 25m to 80m.
