Toyota's Latest Virtual Crash Dummy Software Can Model Occupant Posture before Collisions

Studies show that roughly half of drivers take defensive action (such as sudden braking or steering) to avoid collisions, with vehicle occupants commonly bracing themselves at the same time. Occupant posture—whether braced or relaxed—has a significant effect on body movement during a collision. However, current human surrogate models used in virtual crash simulations are unable to simulate the reflexive defensive actions that humans take in the moments before an imminent collision, such as bracing one's body for impact.
