Toyota introduces THUMS Version 5

Toyota has introduced a new version of THUMS (Total Human Model for Safety). THUMS is used for replicating the behaviour of a human body during a crash. This new version contains a software to simulate the muscles, bones and skin in the human body.

The most important component of a crash test is a crash dummy. Crash dummies are fitted with sensors and load cells that measure the areas where the impact force is maximum during a collision.

Toyota’s THUMS Version 5 is the most advanced iteration of crash dummy design and features a muscle modelling feature. This simulates how a driver braces himself for impact. The results of these simulations can used for designing pre-collision technology. This also helps in accurately studying the performance of seat belts, airbags and other safety equipment.

Toyota began development of THUMS in 1997, working with Toyota Central R&D Labs. Version 1 was launched in 2002. Version 2 was introduced in 2004, which added face and bones to the model. In 2006,Version 4 was created, which had a precise brain model. The more advanced Version 4 was built, with a detailed modelling of internal organs.

THUMS Version 5 has already been adopted by a variety of automotive businesses.
