The first section of this report addresses the issues of vehicle control during transition maneuvers in Intelligent Vehicle Highway Systems. Transition maneuvers include automatic lane change of vehicles and merging and splitting of platoons of vehicles in the automated highway system. The...

The goal of this dissertation is to design controllers that guarantee collision-free operation of vehicles on an Automated Highway System (AHS) using platooning. It begins with an overview of the AHS control system. The individual layers of the hierarchical control architecture for platooning...

This paper presents fuzzy logic traction controllers and their effect on longitudinal vehicle platoon systems. A fuzzy logic approach is appealing for traction control because of the non-linearities and time-varying uncertainties in traction control systems. One fuzzy controller estimates the...

This document is a reference manual for SHIFT, a description language for dynamic networks of hybrid systems. This model offers the proper level of abstraction for describing complex applications such as highway and air traffic control systems, robotic shopfloors, and other systems whose...

The purpose of this report is to investigate the effect of selected parameter variations on the response of a platoon. The response of a platoon under different control algorithms is also examined. A four-car platoon with prescribed lead car dynamics was used for simulations and vehicles in the...

Presents a sketch of a system architecture for the control and management tasks of an intelligent vehicle/highway system (IVHS)

In this report, a combined longitudinal and lateral eighteen-state vehicle chassis, engine, and drive train model is developed and validated against existing longitudinal-only and lateral-only vehicle models. The full-size model is simplified to a three-state model to facilitate controller...

This document is a users manual for DYN-OPT, a linear program that optimally and dynamically assigns traffic to lanes on an automated highway. The program maximizes the total flow across the highway over a pre-specified length of time. DYN-OPT solves a path-based formulation in which the highway...

This study reports on a preliminary design of a health monitoring system for automated vehicles. A new detailed nonlinear vehicle simulation which extends the current simulation is documented and will be used as a future testbed for evaluating the performance of the health monitoring system. A...
