Modeling and simulation of an advanced intelligent restraint system

In every vehicle collision, the work-energy principle must be satisfied, i.e., the work done in stopping the driver must be equal to the driver´s kinetic energy. Existing restraint systems such as airbags and seatbelts are designed to minimize injuries by smoothly absorbing the kinetic energy of the occupant during a crash event. Advanced systems are being developed to tailor their level of restraining to the severity of the crash, weight, size and position of the occupant. Starting with a lumped parameter model and ending with a complete crash simulation environment, this paper introduce and demonstrate the benefits of real time control of a novel adaptive restraint system using intelligent control techniques.
