  We provide an ice friction model for vehicle dynamics of a two-man bobsled
which can be used for driver evaluation and in a driver-in-the-loop simulator.
Longitudinal friction is modeled by combining experimental results with finite
element simulations to yield a correlation between contact pressure and
friction. To model lateral friction, we collect data from 44 bobsleigh runs
using special sensors. Non-linear regression is used to fit a bob-specific
one-track vehicle dynamics model to the data. It is applied in driving
simulation and enables a novel method for bob driver evaluation. Bob drivers
with various levels of experience are investigated. It shows that a similar
performance of the top drivers results from different driving styles.
