Toyota enhances THUMS software for safer vehicles
24 Sep 2017 - 10:58
In a move aimed at developing safer vehicles, Toyota will utilise new additions to its Total Human Model for Safety (THUMS) virtual crash dummy software to eliminate traffic fatalities and injuries while making an even more diverse range of testing possible.
Toyota has added three new models to represent children aged ten, six, and three to Version 4 of the software. THUMS allows injuries sustained by human bodies during vehicle crashes to be simulated on the computer.
THUMS forecasts the extent of injuries sustained throughout the human body, and thus, is utilised in the technological development of passenger protection devices such as airbags, and to contribute to improved vehicle safety performance. THUMS is also increasingly being used in the field of motorsports. For example, it has been used by NASCAR (the US-based National Association for Stock Car Auto Racing) to analyse high-speed impacts, leading to better seat structure design thereby reducing the likelihood of rib fractures sustained by drivers as a result of racing accidents.
The ten-year old (138cm tall), six-year old (118cm tall) and three-year old (94cm tall) additions to THUMS Version 4 represent the average physique of children at each respective age. As with the large male (189cm tall), average-build adult male (179cm tall), and small female (153cm tall) models that are already being sold, the new models will come in two versions - a passenger version and a pedestrian version - for a total of six new additions to the THUMS line-up. This expanded line-up takes into consideration the influence of age and physique, and allows for a more thorough injury analysis.
“Toyota since its founding has been committed to producing vehicles that are safe and provide peace of mind,” said Takayuki Yoshitsugu, Chief Representative, Middle East and North Africa Representative Office, Toyota Motor Corporation. “The addition of the new child models provides a valuable tool in the development of safer vehicles. Toyota has consistently conducted safety-related activities based on three pillars: development of safe motor vehicles, educational activities concerning traffic safety, and participation in traffic-environment development.”
