Meet Thums

Since 1997, Toyota, Japan, has been developing computer-based virtual human models, known as THUMS, to analyze and simulate situations that are closer to the actual accident.

A fundamentally radical approach to crash testing

Since 1997, Toyota, Japan, has been developing computer-based virtual human models, known as THUMS, to analyze and simulate situations that are closer to the actual accident.

Toyota analyzes crash simulations involving THUMS to pinpoint recisely which parts of the human body are affected by various high-impact collisions. The obtained data is used to develop airbags and seats that help reduce injuries in certain collision scenarios.

THUMS is constantly being improved to add more human types and more detailed replicas of internal body structure to derive accurate test results.


Thums anatomy

THUMS consists of bone structure, ligaments and tendons to replicate human bodies. THUMS is used to evaluate the impact on the passengers in automobile crashes.
