MOTOR VEHICLE SAFETY ARRANGEMENT AND METHOD

摘要

Embodiments herein relate to a motor vehicle safety arrangement and method for positioning an occupant properly on a vehicle seat and restraining the occupant thus positioned in preparation of the vehicle potentially being subject to a rear-end collision. A safety belt is associated with the vehicle seat and an electric reversible safety belt retractor is associated with the safety belt. A rearward-looking detection system detects and classifies the collision risk for an approaching object. At least one sensor monitors one or more vehicle parameters. A control unit determines a driving state as critical or non-critical from the monitored vehicle parameters. The control unit controls the electric reversible safety belt retractor to apply a predetermined pullback force on the safety belt in response to the collision risk for an approaching object being classified as high within a predetermined time of an indicated critical driving state.

1. A safety arrangement for a motor vehicle for positioning an occupant properly relative to a back rest of a vehicle seat and restraining the occupant thus positioned on the vehicle seat in preparation of the vehicle potentially being subject to a rear-end collision, wherein the vehicle includes a safety belt associated with the vehicle seat and an electric reversible safety belt retractor associated with the safety belt, the safety arrangement comprising:
a rearward-looking detection system for detecting and classifying collision risk for an approaching object; at least one sensor for monitoring one or more vehicle parameters; and a control unit arranged to determine a driving state as critical or non-critical from the one or more monitored vehicle parameters, wherein the control unit is operable to control the electric reversible safety belt retractor to apply a predetermined pullback force on the safety belt to pull the occupant into the vehicle seat in response to the collision risk for an approaching object being classified as high within a predetermined time of an indicated critical driving state.
