1. An interior system for absorbing an impact to a passenger in a vehicle, comprising:
- a plurality of interior elements mounted to the vehicle, each said interior element having a position state with respect to the passenger;
at least one actuator for each of said plurality of interior element, said actuators producing said position states of said interior elements;
first sensor means mounted to the vehicle for detecting parameters of a vehicle collision;
second sensor means mounted to the vehicle for visually detecting position of the passenger in real time before, during and after a collision; and
a microcomputer based control unit disposed to control said actuators responsive to said first sensor means and said second sensor means,said microcomputer based control unit including;
means for estimating movement of the passenger upon, during and after said collision of the vehicle responsive to said second sensor means detecting position and,means for computing an optimum position state of said plurality of interior elements in a manner to minimize impact to the passenger, responsive to said element estimating means, and for generating a signal to control said plurality of actuators to adjust said plurality of interior elements to said optimum position state during the collision.

Abstract
An interior system for an automotive vehicle comprises interior elements, actuators for the interior elements, and sensors. When a vehicle collision data reveals a vehicle collision, a passenger'"'"'s behavior is estimated in response to passenger data and first vehicle data collected, and a second vehicle data stored. A characteristic value of each interior element is computed in a manner to minimize an impact to a passenger in accordance with the passenger'"'"'s behavior estimated. Then, the actuators are controlled in response to the characteristic value computed.

9. A method of controlling an interior system for absorbing an impact to a passenger in a vehicle, the interior system including a plurality of interior elements mounted to the vehicle, each having a state with respect to the passenger, a plurality of actuators for the plurality of interior elements, each adjusting the state of each of the plurality of interior elements, a plurality of first sensors mounted to the vehicle for detecting parameters of a collision of the vehicle, and a plurality of second sensors mounted to the vehicle for detecting a position of the passenger, the method comprising the steps of:
-
visually detecting passenger position in real time before, during and after a collision; estimating movement of the passenger based upon said visual detection before, during and after the collision of the vehicle and; computing an optimum state of each of the plurality of interior elements to minimize the impact to the passenger upon and during the collision of the vehicle responsive to said movement estimating means, and generating a signal to adjust said plurality of actuators. - View Dependent Claims (10, 11)
