ACTIVE SAFETY APPARATUS FOR VEHICLES AND METHOD OF CONTROLLING THE SAME
First Claim
Patent Images
1. An active safety apparatus for a vehicle, comprising:
- an impact sensing unit for sensing an impact acceleration of the vehicle;
an active controller for estimating a vehicle behavior using an impact acceleration pulse output from the impact sensing unit, estimating a passenger behavior according to the estimated vehicle behavior, setting a target value of the passenger behavior which satisfies a restraining condition realizing passenger safety according to the estimated passenger behavior, setting an operating amount of an active safety device to realize the target value of the passenger behavior, and operating the active safety device according to the operating amount; and
a sensing unit for sensing a result of operating the active safety device and sending the sensed result to the active controller.

Abstract
An active safety apparatus for vehicles and a method of controlling the apparatus, which can actively control the operation of a safety device, such as an airbag device or a seatbelt device installed in a vehicle for restraining a passenger behavior and protecting a passenger in a vehicle collision, based on the conditions of a vehicle collision and the passenger behavior which vary depending on the conditions of the vehicle collision, thereby optimally protecting the passenger for the conditions of the vehicle collision and improving passenger safety of the vehicle.
