Increasingly stringent international passenger safety norms and the need to reduce vehicle body weight for environmental and protection requirements demand efficient and innovative design methods. Computer simulation, or virtual testing, allows an integrated evaluation of these aspects in the early design stages and thereby reduces costs for prototyping and reduces time-to-market. This paper deals with the application of virtual testing in vehicle passive safety design to: (1) reduce injury numbers by enhancing passive safety for a wide range of conditions, and (2) reduce the duration and costs of the vehicle design by improving the efficiency of the design process. A validated virtual test procedure will be developed to extend the range of protection beyond current regulations to real life crash conditions. This will be achieved by 1) developing procedures and guidelines to standardise numerical models and simulations; 2) accounting for the experimentally observed scatter in simulations by stochastic modelling; and 3) identify gaps in current regulations where occupants are not optimally protected. All steps needed for acceptance of this virtual test procedure in regulations or in a consumer test method will be taken into account.
