Real-time controlled restraint systems

This paper presentes manageable models of an occupant and restraint system. Low-order design models are essential in the development of active restraint systems, which aim at lowering certain injury criteria by real-time control of the occupant motion with restraint actuator. The design models are constructed from first principles, using knowledge obtained from sensitivity analysis of a reference occupant model. the models can easily be employed for controller and observer design, and can be used in real-time injury prediction. The desing model is validatedin a variety of frontal impact simulations, and the most important biomechanical responses are compared to the responses of the reference model
