Design and Development of Pop-up Engine Hood System with Dual Elastic Buffer and Evaluation of Performance of Pedestrian Protection

摘要

Based on the purpose of pedestrian protection, a new Pop-up Engine Hood System (PEHS) with an effect of elastic butter is developed to reduce the injury of pedestrians in unavoidable human-car collision situation. Using the fusion of computer vision and laser scanner technology is the best way to tackle the problem of both responsiveness and robustness. Critical parameter of the device is determined. And a reusable PEHS using mechanical spring is designed by using optimization method. After setting up the 3-dimensional model and physical model, the performance of bouncing and injury protection of the system has been proved by kinematics simulation and prototype experiment.
