Starting in January 2021, Toyota will provide its Total Human Model for Safety software free for users worldwide.
Toyota first launched this software system, often referred to by the acronym THUMS, in 2000. It was the world’s first software to simulate a virtual human body and analyze crash injuries.
Since that time, Toyota has updated THUMS to include human models of different ages, genders, and physical attributes. The company has also increased the fidelity of the software’s bone structure, musculature, internal organ, and brain simulations. This means that THUMS can now analyze potential injuries to both car occupants and pedestrians.
Representatives from Toyota claim that THUMS is a massive leap forward over physical test dummies, as the virtual simulations more accurately depict the particular shapes and strengths of different human body parts during an impact.
Influential tech for all
THUMS is currently in use at over 100 universities, suppliers, vehicle manufacturers and research institutes globally, with the National Highway Traffic Safety Administration and Insurance Institute for Highway Safety considering making THUMS a part of their assessments.
Seigo Kuzumaki, Toyota’s head of advanced R&D and engineering, says the decision to make THUMS freely available is an attempt “to further enhance vehicle safety across the entire automotive industry and to help reduce traffic injuries and fatalities.” Toyota hopes making THUMS freely available will both further vehicle safety research and enable users to improve the system’s human models.
