As the number of vehicles is increasing, the number of accidents is also increasing. Recently, customers are requiring safer vehicles, so vehicle makers are equipping not only the frontal airbags but also side airbags. Many countries regulate the vehicles safety and develop the NCAP with more severe criteria. To meet these customer requirements and NCAP criteria, it is important to deploy the airbags properly. Side crash sensors are needed to deploy the side airbags. In this study, the method for selecting the robust position of crash sensors at C-pillar was proposed using DFSS methods. First, 4 points were selected with consideration of other parts like holes and harness. Then CAEs with various MDB were performed and get acceleration data from selected points. Each pulses were scaled with ±10% and velocities of each pulse were calculated. From theses velocity, The time when the velocity crossed threshold was used for TTF(Time to Fire). Because faster times of airbag deployment were usually required, DFSS was performed as ‘smaller the better’ criteria. The selected point was verified with 2nd row pole test. In conclusion, response of C-pillar acceleration sensors were better than acceleration from B-pillar sensor and robust position could be selected with this DFSS method.
