Toyota develops new software to model occupant posture

Xinhua/BSS, TOKYO: Japanese automaker Toyota Motor Corp on Friday announced that it has developed virtual human model software which could simulate posture changes of vehicle occupant prior to collisions and thus may help improvement of safety technologies to better protect occupants.
“Toyota has added a new muscle model capable of simulating human postural states in the latest version of its Total Human Model for Safety (THUMS) virtual human model software,” said the car giant in a release.
“THUMS Version 5 can simulate a variety of states from relaxed to braced, thus enabling more detailed computer analysis of injuries caused by collisions,” it said.
Until now, THUMS was only able to simulate changes in posture post-collision. However, with THUMS Version 5’s new muscle model, changes in occupant posture prior to collisions can now be simulated.
This makes it possible to more accurately study the effectiveness not only of seatbelts, airbags and other safety equipment, but also of active safety technologies such as pre- collision systems. “In turn, this will lead to development of active safety technologies that better protect vehicle occupants,” said Toyota.
