Semi-Autonomous Adaptive Cruise Control in Mixed Traffic

Abstract

Platoon of vehicles is a last purpose of the AHS (automated highway systems) which is a part of ITS (intelligent highway systems). Platoon that forgives mixture of automated vehicles and manually driven vehicles attracts much attention recently. In this paper, a platoon control law based on adaptive neural network (ANN) to lower level and semi-autonomous adaptive cruise control (SAACC) to upper level is proposed. Moreover, variable time-gap (VTG) policy is adopted as a spacing policy to satisfy traffic flow stability. We confirmed that the closed loop system is stable, and confirmed the effectiveness in the numerical simulation
