AirbParameter setting of airbag control electronic devices requires lots of costly and time consuming real destructive and non destructive test on complete vehicle prototypes. For the first time in a project time frame, AUTOLIV and RENAULT have successfully lead single-point sensing CAE based calibrations for front and rear algorithms and multi-point sensing CAE based calibration for side algorithm. For front algorithm, even if single-point sensing calibration seems to be more difficult than multi-point sensing calibration, a similar case study would be necessary for a multi-point sensing calibration to assess the CAE compliance, whatever the sensing architecture. CAE based calibration of crash algorithm is only at its enfancy and is not yet a standardised techniques for calibration. This case study will provide a tremendous return of experience to: 1. underline the reasons of this success and the potential remaining risks, 2. define guidelines for CAE modelling and calibration, 3. be able to succeed once again in an another car project. The collaboration between AUTOLIV and RENAULT will continue to introduce improvements concerning CAE modelling and algorithm design, modifications of calibration.
