Supervised adaptive dynamic programming based adaptive cruise control

Abstract

This paper proposes a supervised adaptive dynamic programming (SADP) algorithm for the full range Adaptive cruise control (ACC) system. The full range ACC system considers both the ACC situation in highway system and the stop and go (SG) situation in urban street way system. It can autonomously drive the host vehicle with desired speed and distance to the preceding vehicle in both situations. A traditional adaptive dynamic programming (ADP) algorithm is suited for this problem, but it suffers from the low learning efficiency. We propose the concept of inducing range to construct the supervisor and finally formulate the SADP algorithm, which greatly speeds up the learning efficiency. Several driving scenarios are designed and tested with the trained controller compared to traditional ones by simulation results, showing that trained SADP performs very well in all the scenarios, so that it provides an effective approach for the full range ACC problem.
