Predictive impact sensing system for vehicular safety restraint systems

摘要

An improved safety restraint system for a motor vehicle including: safety restraint device such as a seat belt and air bag(s) for protecting an occupant during a crash, a processor for predicting the collision of an obstacle with the motor vehicle and for generating an output signal to activate various actuators, actuators for activating the restraint devices in dependence with an output of the sensors various sensors including a radar microwave or millimeter wave system for generating and propagating electromagnetic radiation waves and to receive reflected waves, the transmitted and received waves being of predetermined frequency, wavelength, spectrum, duration and power to provide a desired sensing range and response.
