A Stochastic Model Predictive Control Approach for Driver-Aided Intersection Crossing With Uncertain Driver Time Delay
We investigate the problem of coordinating human-driven vehicles in road
intersections without any traffic lights or signs by issuing speed advices. The
vehicles in the intersection are assumed to move along an a priori known path
and to be connected via vehicle-to-vehicle communication. The challenge arises
with the uncertain driver reaction to a speed advice, especially in terms of
the driver reaction time delay, as it might lead to unstable system dynamics.
For this control problem, a distributed stochastic model predictive control
concept is designed which accounts for driver uncertainties. By optimizing over
scenarios, which are sequences of independent and identically distributed
samples of the uncertainty over the prediction horizon, we can give
probabilistic guarantees on constraint satisfaction. Simulation results
demonstrate that the scenario-based approach is able to avoid collisions in
spite of uncertainty while the non-stochastic baseline controller is not.Comment: Submitted to European Control Conference 2019 (ECC19
