Enhanced occupant spring mass model for use with an actuatable restraint system including compensating for monotonicity of misuse conditions |
摘要 |
An apparatus for switching the value of a spring constant K used in a spring mass model (54, 56, 60, 70, 76) for modeling a vehicle occupant in an occupant restraint system (20) includes a sensor (22) for sensing a crash event and providing a crash signal (40) indicative thereof. The spring mass model adjusts the acceleration signal and determines a virtual velocity value (72) and a virtual displacement value (78). The spring value K of the spring mass model is controlled in response to the determined virtual velocity value and the determined virtual displacement value relative to associated switching quadrants defined by predetermined velocity and displacement thresholds.
