| Total Human Model for Safety (THUMS) |
| The THUMS (Total HUman Model for Safety) is a computational model to simulate gross motions and stress or strain distributions of the human whole body for impacts, using finite element method. The THUMS reproduces anatomical geometry data and biomechanical properties of the human body such as the stiffness of the bone and the flexibility of the skin. The feature of the THUMS is that each joint of the THUMS was modeled anatomically with the major ligaments and tendons. Adjusting the size and shape of each element of the model enabled to reduce the computational time and make analyses faster in spite of the total element of more than 100 000. The THUMS has the possibility of detailed investigations of the gross motions of the human body and stresses or strains on the bones and the joints for impacts. The THUMS represents a mid size adult male with a height of 175 cm, a weight of 77 kg and an age of 30 to 40 years. |

| All new projects and products must be justified on real traffic safety needs and Autoliv is therefore following the Top-Down approach. In parallel the technology development is actively followed in order to find the best technology for a real life traffic safety need. Today this work is for instance focused on how to best use the possibilities offered by pre impact sensors or how to design sensor system for Alco locks. Other areas are how to use the airbag technology in airbags located on the vehicle exterior for improved protection for pedestrians or improved compatibility between larger and smaller cars. How far infrared (FIR) can be used to detect pedestrians and reduce injuries to them is an other area where technology and real life traffic safety merge in an Autoliv research project.
