VEHICLE AIRBAG INFLATION CONTROL METHOD

摘要

An airbag deployment system (1) comprising an airbag inflator (3) operable to inflate the airbag at a variable rate dependant upon a signal from an airbag actuator (5), a sensing system (7) arranged to detect the presence of an object in a predetermined area relative to the vehicle and to detect the velocity and direction of movement of the object relative to the vehicle, and feeds this information to a collision prediction unit (9) which calculates the impact velocity of the impending collision, and feeds a signal to the airbag actuator (5) to indicate the rate of inflation required for the optimum protection to be provided by the airbag. Typically the sensing system (7) is a radar sensing system.
