Abstract: Provided is an airbag control unit with inertial measurement unit (IMU) integration, which includes an airbag collision sensor configured to detect airbag collision information; a digital sensor configured to detect a yaw rate and an acceleration, and to convert a detected data to a digital signal; and a micom configured to identify whether an output from the digital sensor and an output from the airbag collision sensor are within a measurement range of a corresponding sensor.

Abstract: Disclosed herein is a collision detection system for a vehicle. The collision detection system for a vehicle according to the present invention includes a sensor unit and a control unit. The sensor unit measures impacts A and B along two axes that intersect each other in diagonal directions. The control unit calculates a longitudinal impact X and a transverse impact Y using the measured impacts A and B, and determines the direction of collision and whether to operate at least one device for protection against collision-related injury using the impacts.

Abstract: A first exemplary embodiment of the present invention includes detecting pressures applied to a left front wheel, a left back wheel, a right front wheel, and a right back wheel; and judging that the possibility of roll over exists if any of the pressures applied to the left wheels, the right wheels, or the front wheels is greater than a reference pressure. A second exemplary embodiment of the present invention includes detecting pressures applied to the wheels; and judging that the possibility of roll over exists if a difference in the pressures of the left wheels and the right wheels, or the pressures of the front wheels and the back wheels, is greater than a reference difference. The method may further include controlling the wheels if the possibility of roll over is judged to exist.
