Adaptive cruise control (ACC) systems are designed
basically to improve comfort, safety and traffic smoothness.
The expected diffusion of vehicle-to-vehicle (V2V) communication
systems allows now adding additional information on
the expected behavior of nearby vehicles, thus offering the possibility
to extend the targets of ACCs to include fuel efficiency.
In earlier works, it has been shown both by simulations and
measurements that the corresponding potential can be quite
high. However, the on-line implementation of the method can
have prohibitive costs. Against this background, this paper
suggests a different solution based on the approximation of
the results of an optimization problem. This is done by using a
Hammerstein-Wiener model combined with additional control
loops to ensure safety related constraints. The method is shown
to provide almost the same performance as the original problem
while requiring only a fraction of the computational effort.
