Toyota's THUMS (Total Human Model for Safety), which was first developed in 1997, is now in Version 7. THUMS has been updated to address changes in people's posture when using advanced driver-assist systems, which are becoming more common among modern cars.
Toyota cited that when a person is in a reclined position, the body reacts differently to seat and restraint systems. Even when sitting up, the change in posture can lead to significantly different effects in the event of an impact, causing varying types of injury. The updates allow THUMS to account for these changes, providing a more accurate prediction of the injuries that could result from a crash.
