6.6 Pre-crash Restraint Deployment (User Service*)

The Pre-Crash Restraint Deployment user service reduces the number and severity of injuries caused by vehicle collisions. This is accomplished by developing means both to anticipate an imminent collision and to activate passenger safety systems prior to the actual impact, or earlier after crash onset than is currently feasible. These safety systems would be more effective if their deployment were based on information such as details of an imminent collision situation (velocity, mass and direction of the vehicle being hit and the vehicle or object it is hitting); and the number, location and major physical characteristics of the vehicle occupants.
