The days of using of test dummies for crash simulations may be over if Toyota and GM have their way. The two fierce rivals are actually working together on a proposal that would allow all the tests to be done using a computer simulation. The benefit this system would have is telling companies the exact wounds occupants would have in a crash. It would also allow them to do more crashes from different perspectives to virtually test for weaknesses in the vehicles, reports Japan’s Nihon Keizai Shimbun newspaper. Toyota has been working on a virtual test system since 2000 called Total Human Model for Safety, but with the combined forces of the two biggest car companies the new system should be much better. They’re expecting to finalise development by 2010.
