OUR DUMMIES ARE ONLY HUMAN Toyota's Crash Test Dummies Replicate Human Reactions

OUR DUMMIES ARE ONLY HUMAN Toyota's Crash Test Dummies Replicate Human Reactions

Date: 2015-07-10
You are in a car and you know you are about to hit something. If you are the driver, you're likely to hit the brakes and turn the wheel; if you're a passenger, aware of what's about to happen, your instinct is to brace yourself for impact.

These changes in posture - relaxed or braced - aren't something physical crash test dummies can copy, but Toyota has produced new software for its THUMS virtual human modelling that replicates these kinds of pre-collision reactions.

The latest version of THUMS adds a muscle modelling feature that can simulate the body attitude of different vehicle occupants, from relaxed to braced, allowing for more detailed computer analysis of the injures collisions can cause.

THUMS Version 5 has already been adopted by dozens of businesses, including vehicle and parts' manufacturers, and is contributing to vehicle safety research worldwide.

Toyota began development of THUMS in 1997, working with Toyota Central R&D Labs. Version 1 was launched in 2002, followed by Version 2 in 2004, which added face and bones to the model; Version 4 in 2006, with a precise brain model; and Version 4 in 2010, which gained detailed modelling of internal organs.
