Toyota has recently announced that three new models will be added to its Total Human Model for Safety (THUMS) software. These models will represent children at the ages of three, six, and ten.  This announcement showcases Toyota’s commitment to safety and marks another milestone for the THUMS virtual crash test dummy software.


The THUMS project began in 1997 as a collaborative effort between Toyota and Toyota Central R&D Labs. THUMS allows researchers to simulate what happens to various parts of the human body in an automobile accident. Features of the body, such as the brain, bones, and skin, can be analyzed in detail. This analysis means that auto manufacturers will have the necessary information to improve the safety of their vehicles in the event of a collision.

Prior Versions

Although THUMS can provide detailed information now, this was not always the case. The first version of THUMS was launched in 2000 with very limited features. Improvements have been made over time, which have added muscles, organs, and the brain to the software. These improvements have taken place in the span of 15 years.

2003 Version 2 Face and Bone
2008 Version 3 Brain
2010 Version 4 Internal Organ
2015 Version 5 Muscle

New Child Models

Child Crash Test Dummy Models
THUMS is now able to produce information that depicts what will happen to children of the ages of three, six, and ten. Toyota partnered with researchers from the University of Michigan, Wayne State University, and the Collaborative Safety Research Center in Michigan to perfect the models that the software uses.

In an effort to be as accurate as possible, the researchers took the average physiques of each respective age and used them for the models. This will give analysts the best opportunity to forecast what can happen to a child in the event of an automobile accident.

Toyota has stated that each model will come in two different versions, which means six total models will be available for sale this autumn. A passenger and a pedestrian version of each age will give researchers thorough insight on injuries that might occur in a crash.

Other Uses of THUMS

While THUMS was initially created to help keep everyday drivers safe, it is increasingly being used in motorsports. Researchers are also using the software to design racing seats that will keep race car drivers safe in the event of a crash. As a result, the likelihood of rib fractures to race car drivers has been reduced with the use of the software.

A Worldwide Impact

Toyota has made a worldwide impact by designing and releasing the THUMS software. THUMS can be purchased by any organization, as Toyota's goal is to eliminate fatalities and injuries sustained by both passengers and pedestrians. With the software’s continued development, Toyota is well on its way to accomplishing this.
