Abstract:
Whiplash injuries resulting from vehicle collisions are still a significant
socio-economic issue across the world. Years of research has resulted in the
development of injury criteria, restraint systems and a deeper understanding of
the injury mechanism. However, some grey areas remain and, in the context of the
increasing automation of vehicles, one can wonder how the injury mechanisms may
change due to changes in collision forces or directions. This article presents
an experiment with ten volunteers subjected to two braking modes, including
automated braking preceded by an alarm warning or robot human braking, in three
different initial head positions: forward facing, lateral rotation and flexion
rotation. The volunteers were equipped with inertial measurement units to record
their head and neck dynamics. Results show that the initial position of
volunteers implies differences in the volunteer head dynamics. Also, the
auditory alarm emitted prior to the emergency braking may have helped the
volunteers to mitigate the mechanical stimulus and most likely the injury
risk.
