Abstract: | Driver assistance systems have become more and
more important in recent years due to the increasing degree of
automation in road traffic ? especially with regard to safety.
Often a driver?s perception of a situation is prone to inaccuracy,
particularly on country roads. Consequently, there is a high
mortality rate due to frontal collisions with oncoming traffic
(among others). One of the most dangerous maneuvers that
leads to such conflicts is overtaking. Overtaking involves other
traffic participants and therefore uncertainties exist. We cope
with this challenge by introducing a system that evaluates the
options a vehicle has during overtaking (completing or aborting
the maneuver) using stochastic models of the surrounding
traffic. The stochastic models are used to predict the movements
of surrounding road users. As a next step, the general feasibility
of the possible maneuvers is checked and rated. The results of
this analysis can either be directly used for longitudinal control,
be forwarded to a low level controller, or serve as a guideline
for the decision-making process of a human driver. |
