The project "Lateral Control of Heavy Duty Vehicles for Automated Highway Systems" (MOU 313) represents continuation of the heavy vehicle research in PATH which was initiated in 1993 with MOU 129, "Steering and Braking Control of Heavy Duty Vehicles" and was followed with MOU 242, "Steering and...

This dissertation presents a hierarchical, hybrid point of view to the control of large-scale systems. The analysis is based on a new hybrid dynamical system formulation that allows for the modelling of large scale systems in a modular fashion. Three problems are addressed: controller design,...

This report continues work on the design of a health monitoring system for automated vehicles. The approach is designed to fuse data from dissimilar instruments using modeled dynamic relationships and fault detection and identification filters. Issues relating to sensor models, output...

This report describes the results of a one year effort to implement and analyze the performance of a Differ- ential Global Positioning System (DGPS) aided Inertial Navigation System (INS) for possible future use in Advanced Vehicle Control Systems (AVCS). The initial premise of this project was...

This report presents an evaluation of the Phase II Smart Card Demonstration Project, the goal of which is to develop a transit fare payment system for commercialization that will improve transit efficiency and effectiveness. The major focus of the project is the testing of selected technologies...

This document presents Dynamic Visualization, a project associated with the California PATH Program. The objective of the project is to develop a software which can animate automated highways, visualize the dynamics of automatic vehicles, and help the design and evaluation of automatic vehicle...

In this research, the authors focus on the problem of designing hierarchical, hybrid controllers for large scale systems. An overview of the proposed design process is first given. A modeling formalism is then introduced which allows for the modeling of multi-agent systems with hybrid dynamics...

In this dissertation, the problem of fault tolerant control of automobiles is addressed. The three main problems handled in the dissertation are tire burst, sensor fault detection and slip angle control. The tire burst and sensor faults are important failure modes for automated highways, whereas...

This study focusses on the development of navigation and route guidance technologies with an emphasis on existing systems, industrial strategies, market approach and human factors considerations. By considering the different situations in the US, Europe, and Japan the report analyzes the...

The major accomplishments from this project can be categorized into the following areas: (1) Adoption of a vehicle-collision simulation tool with an interface that allows the implementation of feedback controller. (2) Thorough analysis and modeling of vehicle lateral dynamics in collision...
