The population health of endangered Key deer (Odocoileus virginianus clavium) was monitored from 10 February 1986 to 28 September 2000 by necropsy of animals that were killed by vehicles, euthanized because of terminal injuries or disease conditions, or found dead. The predominant mortality factor during the period was collision with motor vehicles; however, several infectious diseases were dia...

In this paper, we address -tracking and -stabilization for a class of SE(2) autonomous vehicles with firstorder nonholonomic constrains. We introduce a class of transformations called near-identity diffeomorphisms that allow dynamic partial feedback linearization of the translational dynamics of this planar vehicle. This allows us to achieve global exponential -stabilization and -tracking (in p...

Assuring safety of autonomous vehicles operating in an open environment requires reliable situation awareness, action planning and prediction of actions of other vehicles and objects. Factors that also have to be considered are certainty and completeness of available information and trust in information sources and other entities. The paper discusses the problem of autonomous vehicle safety ass...

The focus of this paper is the n-vehicle collision avoidance problem. The vehicle model used here allows for three-dimensional movement and represents a wide range of vehicles. The algorithm works in conjunction with any desired controller to guarantee all vehicles remain free of collisions while attempting to follow their desired control. This algorithm is reactive and distributed, making it w...

In this paper we present a methodology based on multiple models and switching for realtime estimation of center of gravity (CG) position in automotive vehicles. The method utilizes well-known simple linear vehicle models for lateral and roll dynamics and assumes the availability of standard stock automotive sensors. We illustrate the technique with numerical simulations as well as with measured...

The development of accurate control systems for underwater robotic vehicles relies on the adequate compensation of thruster dynamics. Without compensation, the closed-loop positioning system can exhibit limit cycles. This undesired behaviour may compromise the overall system stability. In this work, a fuzzy sliding-mode compensation scheme is proposed for electrically actuated bladed thrusters,...

The passive and also the active safety systems of the vehicles evolved in the last decades. Beside the safety system of cars and trucks the smaller vehicles like the motorbikes, scooters, e-bikes and bicycle’s systems evolved as well. The aim of the project was to create and develop a prototype bicycle that uses a hydraulic type antilock braking system. The paper presents shortly the dynamics o...

Multi-vehicle routing problems in systems and control theory are concerned with the design of control policies to coordinate several vehicles moving in a metric space, in order to complete spatially localized, exogenously generated tasks, in an efficient way. Control policies depend on several factors, including the definition of the tasks, of the task generation process, of the vehicle dynamic...

In this paper, we propose a framework for formation stabilization of multiple autonomous vehicles in a distributed fashion. Each vehicle is assumed to have simple dynamics, i.e. a double-integrator, with a directed (or an undirected) information flow over the formation graph of the vehicles. Our goal is to find a distributed control law (with an efficient computational cost) for each vehicle th...

In this paper, a new model for traffic on roads with multiple lanes is developed, where the vehicles do not adhere to a lane discipline. Assuming identical vehicles, the dynamics is split along two independent directions—the Y -axis representing the direction of motion and the X-axis representing the lateral or the direction perpendicular to the direction of motion. Different influence graphs a...
