Toyota is taking safety to the next level by not just making their vehicles better but also by looking deeper into how our muscles react during the moment of collision.

Studies have indicated that about 50-percent of drivers perform defensive acts like sudden braking or steering in order to avoid an accident while the vehicle’s occupants instinctively take a protective posture.

This is what Toyota wants to study in detail, how the muscles brace the body for a collision and how these positions help protect the body during impact.

Before the introduction of the new muscle model in Toyota’s Total Human Model for Safety (THUMS), the software had no way of simulating how a human body gets ready for a collision.

THUMS Version 5 addresses this problem by allowing the software to mimic muscle movement and come up with several human postures during the simulation of a collision including imitating how the body reacts from a relaxed to a braced position.

This new development allows Toyota to ‘more accurately study the effectiveness of seatbelts, airbags and other safety equipment’ while also working on the improvement of active safety technologies in the vehicles in order to better protect passengers.

THUMS has already been adopted by dozens of companies, including automobile and parts manufacturers, and is contributing to vehicle safety research all over the world.
