Apparatus for protecting passenger of autombile and control methodlamp
First Claim
1. An apparatus for protecting a passenger of an automobile, comprising:
- an automobile body;
a single biaxial Front Impact Sensor (FIS) mounted at a front center of the automobile body and sensing decelerations on an X axis which is in a length direction of the automobile body and a Y axis which is in a width direction of the automobile body during an automobile impact;
a deceleration meter sensing a first deceleration in the length direction of the automobile body during the automobile impact; and
a controller determining an airbag splaying time based on a displacement value and a predicted displacement value moving forward from an initial position of the passenger calculated based on the first deceleration, and an X-axial velocity variation and a Y-axial velocity variation measured by the single biaxial FIS.
