The Research of Intelligent Seat Belt Pretension System Based on Active Safety

Abstract

Six early-warnning subsystems are build, the control parameters of tension value and time for seat belt are determined, based on the analysis of function and components for intelligent seat belt pretension system. The hardware and software are designed, the software for seat belt retractor motor is integrated to set the ralative time distance, vehicle yaw rate, steering wheel angle, vehicle deceleration, this four signals which are used as input for simulation, the output show that the tension value and tension force are directly proportional to input signal, which can be early warn for intelligent seat belt successfully and provide passengers active safety effectively.
