Saving fuel using wireless vehicle-to-vehicle communication

In this paper, we compare two different connected cruise control strategies that utilize vehicle-to-vehicle (V2V) communication to monitor multiple vehicles ahead in order to save fuel. One strategy uses direct feedback while the other is based on dynamic optimization that assigns the control action in a receding horizon fashion while relying on preview information about the vehicle immediately ahead. We demonstrate that both methods produce significant fuel improvements but the performance of the second controller depends significantly on the length of time horizon as well as the accuracy of the preview information.
