Method for robust occupant position control prior to vehicle impact

摘要

A method for robust occupant position control prior to vehicle impact is provided. The method includes, in response to detecting an object, generating a Collision Index (CI) value representing a likelihood of collision with the detected object, and generating a Lateral Displacement (LD) value indicative of a distance to the detected object. A weight value (Wo) for a vehicle occupant is also determined. When the CI and LD values exceed respective thresholds, the method generates a pretensioner output (PTout) value as a function of the CI and Wo values, and activates a seatbelt pretensioner associated with a seat of the vehicle occupant as a function of the PTout value. An occupant positioning system for a vehicle activated prior to vehicle impact is also provided.
