APPARATUS AND METHOD FOR OPERATING PRE-CRASH DEVICE FOR VEHICLE
First Claim
1. A pre-crash operating device for a vehicle comprising:
- a scanning sensor unit for scanning objects around the vehicle;
a sensor unit for sensing drive information of the vehicle including a velocity, an acceleration, an steering angle, a yaw rate and a brake pressure;
a safety device unit to be actuated prior to a collision and to protect occupant; and
a control unit for computing offset value and relative velocity between the vehicle and the object by using the driving information from the sensor unit of the vehicle, thereby determining an imminent collision object and actuating the safety device when a predicted collision time induced from the relative velocity of the imminent collision object is within a predetermined time.

Abstract
A pre-crash operating device for a vehicle includes a scanning sensor unit for scanning objects around the vehicle by using laser, a sensor unit of the vehicle for sensing driving information including a velocity, an acceleration, an steering angle, yaw rate and a brake pressure, a safety device unit to be actuated prior to a collision and to protect occupant, and a control unit for computing an offset value and a relative velocity between the vehicle and the object by using the driving information from the scanning unit and the sensor unit of the vehicle, thereby selecting an object as an imminent collision object and actuating the safety device when a predicted collision time induced from the relative velocity of the imminent collision object is within a predetermined time.

8. A operating method of a pre-crash device for a vehicle comprising:
-
sensing drive information including a velocity, an acceleration, an steering angle, a yaw rate and a brake pressure; figuring out a vehicle state through computing and predicting the velocity and the path of the vehicle by using the driving information; scanning objects around the vehicle by using laser of the scanning sensor unit; distinguishing objects through computing and predicting the contour, the path and the velocity of the object by using scanned information of the object; predicting the offset value by using the path prediction between the vehicle and the object and the relative velocity by using the velocity prediction of the vehicle and the object; selecting an object an imminent collision object by comparing the predicted offset value and the relative velocity; and actuating the safety device unit when a predicted collision time induced from the relative velocity of the imminent collision object is within a predetermined time.
