An airbag control apparatus includes: an airbag, an airbag driver that deploys the airbag, and a processor that estimates a vehicle momentum and a crash progress degree based on a longitudinal acceleration and a vehicle speed upon a vehicle crash, determines deployment of the airbag based on the vehicle momentum and the crash progress degree and controls the airbag driver when the deployment of the airbag is determined.

An apparatus and a method of controlling an airbag of a vehicle are capable of securing robustness of an airbag deployment logic and more effectively protecting passengers. The apparatus and method achieve this by determining whether to deploy an airbag based on a post-human injury probability calculated through a human injury probability model and Bayesian network learning (feedback learning). The apparatus includes: a human injury probability calculator configured to calculate a human injury conditional probability and a human injury prediction probability based on vehicle motion information measured by a sensing device; a learner configured to calculate a post-human injury probability by performing a probability-based real-time feedback machine learning based on the human injury conditional probability and the human injury prediction probability; and an airbag deployment determiner configured to determine whether to deploy an airbag based on the post-human injury probability.

A pedestrian protection apparatus may include: an active sensor configured to sense a forward obstacle of a vehicle; a passive sensor configured to sense a collision of the vehicle; a storage unit configured to store a collision threshold value which is set according to the passive sensor and a protection subject; a protection module driving unit configured to drive a protection module for protecting the protection subject in case of a collision with the vehicle; and a control unit configured to identify the protection subject based on the sensing result of the active sensor, adjust the collision threshold value according to the protection subject, compare the sensing result of the passive sensor to the collision threshold value, and operate the protection module driving unit.

Aspects of the disclosure relate to reducing the likelihood of injury to a passenger in a collision. In one example, a computing device may determine that an impact between a vehicle and an object external to the vehicle is imminent. The computing device may determine a protection range for a vehicle's airbag based on characteristics of the passenger, including the passenger's seating location within the vehicle. An airbag extension system may position an airbag package, including the vehicle's airbag, such that the vehicle's airbag is within the protection range of the passenger's seating location.

A system for improving safety of an occupant by a vehicle seat belt, which can provide adaptive protection for an occupant in different seat positions and different sitting postures is provided. A method for improving safety of an occupant by a vehicle seat belt is also provided, along with a a computer-readable medium. The a system for improving safety of an occupant by a vehicle seat belt includes an in-vehicle observation system, an active seat belt system, and an integrated safety domain control unit. The integrated safety domain control unit formulates a vehicle seat belt protection strategy based on received data from the in-vehicle observation system, and a slack state of an active retractor and a positional state of an active lift buckle in the active seat belt system, to implement selective tightening or loosening of the active retractor and/or selective lifting or lowering of the active lift buckle.
