This report provides information on a study assessing the potential for the transition of the fleet of highway vehicles to lean vehicles (General Motors Lean Machine). The report provides information on the organization of the study and the results of preliminary explorations of parking,...

This report will present the results of the initial study to develop an accurate working model of the 40 foot New Flyer Bus powered by the Cummins C8.3+ 280G CNG engine (Figure 1.1). The main focus of the study is the modeling of the vehicle dynamics using step input acceleration data. Other...

In this report, we extend our previous work within MOU 372 on modeling and longitudinal speed control design for heavy commercial vehicles equipped with variable compression braking mechanisms. Previously, we developed a detailed crankangle based simulation model for a six cylinder, 350 hp...

In this paper, a case study of the difficulties encountered in the design of hierarchical, hybrid control systems is presented. The Intelligent Vehicle Highway System (IVHS) architecture proposed for vehicle platooning is used as an example. The authors conclude that the conventional tools...

Automation of highways and in particular platooning of vehicles raises a number of control issues. A hierarchical structure is used to address these issues. The work presented here is an attempt at constructing a consistent interface between discrete event and continuous time controllers. The...

A fuzzy rule-based controller is applied to lateral guidance of a vehicle for an automated highway system. The fuzzy rules, based on human drivers' experiences, are developed to track the center of a lane in the presence of external disturbances and over a range of vehicle operating conditions.

Because hit-and-run crashes account for a significant share of pedestrian fatalities, a better understanding of these crashes will assist efforts to reduce pedestrian fatalities. Of the more than 48,000 pedestrian deaths that were recorded in the United States between 1998 and 2007 (Fatality...

The vehicles in a platoon will experience transient aerodynamic forces as vehicles leave and join the platoon at various locations. A platoon of scale vehicle models is placed in a wind tunnel and measurements are made of the transient forces and moments as one of the vehicles is moved into and...

This report investigates the problem of regulation-level vehicle control for combined lateral and longitudinal maneuvers in an automated highway system (AHS) setting. Intelligent vehicles are assigned to dedicated lanes by a decentralized roadside coordinator which suggests a desired velocity....
