Abstract
This study proposed a method for calculating ΔV that considers the rotational behavior of vehicles during side impact accidents and validated its effectiveness through actual accident data and simulations. While ΔV measured on the airbag ECU location is commonly used for assessing impact in traffic accidents, there is an opportunity to enhance the accuracy of impact assessments by incorporating the vehicle's rotational behavior. The study highlighted the variations in ΔV based on collision locations and introduced a method that utilizes acceleration sensor data from the B-pillar and C-pillar to achieve a more precise impact assessment. Simulation results demonstrated a good correlation with the proposed calculation method, indicating the practicality of calculating ΔV while considering rotational behavior. Future research will focus on gathering additional data to further broaden the applicability of this method, paving the way for continued improvement in impact assessment techniques.
