Modeling and simulation of an advanced intelligent restraint system

Abstract

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.
