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 report presents information on millimeter wave (MMW) radar for automotive longitudinal control. It addresses the fundamental capabilities and limitations of millimeter waves for ranging and contrasts their operation with that of conventional microwave radar. The report analyzes pulsed and...

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 studies the technical deployment of an Automated Highway System (AHS), and specifically, the interface between an AHS and Urban Arteries (UA). The report focuses on four tasks: 1) specify physical arrangement, operational procedures for entry/exit, 2) conceptualize functions of...

This document describes part of the work conducted under MOU252 and MOU324, related to the studies of vehicle collisions in vehicle-following operations. This working paper is a detailed documentation of a computer program that is the core element of the simulation tools for vehicle collision...

This paper investigates the feasibility of a fuzzy logic control (FLC) algorithm for lateral control in a lane change maneuver in an automated highway system (AHS). The lane change maneuver takes the vehicle from lane following control in one lane to lane following control in an adjacent lane. A...

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...

Advanced Vehicle Control Systems (AVCS) require large numbers of sensors for different levels within the control hierarchy. Whereas all sensors contain uncertainty to some degree, different sensors are particularly useful for specific environmental conditions. Therefore, sensor redundancy is...

This report focuses on the design of controllers for platoons of automatically-controlled automobiles using COSPAN computer language. In order to ensure that it is safe to initiate a maneuver, the platoon layer controller enters into a negotiation with its neighbors and is implemented as a...
