By CARSIFU | 11 February 2019


TOYOTA CITY: Toyota Motor Corporation (Toyota) and Toyota Central R&D Labs, Inc. have released Version 6 of the Total Human Model for Safety (THUMS) virtual crash dummy software.

Researched and developed for over 20 years by the two companies, THUMS simulates detailed computer analysis of human body injuries caused by vehicle collisions.

The new software features internal organ modeling and a new muscle model that simulates a variety of occupant postures, including braced and relaxed, permitting a more detailed analysis by anticipating various occupant postures as the widespread deployment of automated vehicles continues to advance.

THUMS is available for purchase through the JSOL Corporation (Tokyo) and ESI Group (Tokyo). The software has been used in vehicle safety technology research by Toyota as well as automobile manufacturers, parts manufacturers, universities, research institutions, and the like, both in Japan and overseas.

As preventive safety equipment becomes more widespread in tandem with the deployment of automated driving technologies, occupants are anticipated to assume a wider variety of postures at the point of collision than previously; in particular, driving support functions may result in drivers assuming a more relaxed posture.

Moving forward, Toyota intends to research and develop technologies that help protect occupants in the event of a collision by utilizing THUMS, and provide safety and security to its customers under a diverse range of conditions.
