The GuideCane is a novel device designed to help blind or visually impaired users navigate safely and quickly among obstacles and other hazards. During operation, the user pushes the lightweight GuideCane forward. When the GuideCane’s ultrasonic sensors detect an obstacle, the embedded computer determines a suitable direction of motion that steers the GuideCane and the user around it. The steer...

The utility of orthogonal collocation methods in the solution of optimal control problems relating to Formula One racing is demonstrated. These methods can be used to optimise driver controls such as the steering, braking and throttle usage, and the optimisation of vehicle parameters such as aerodynamic down force distributions. Of particular interest is the optimal usage of energy recovery sys...

The paper deals with the application of model reference adaptive control to robot impedance control, which is actually a technique of steering the end-effector on a prescribed path and satisfying a prescribed dynamic relationship between the force and the end-effector position. Due to unknown parameters of the environment (stiffness, exact position), a model reference algorithm is proposed whic...

The topology of a remote sensor system changes as a few sensors come up short on force, fall flat or Join the system; which might bring about loss of information or the velocity of exchange of information backs off. This issue is solved using Greedy Algorithm and the Hop Count Reduction (HCR) plan is used as a short-listening so as to slice procedure to decrease the steering bounces to the neig...

This research establishes a “detect-decide-action” agent-based evacuation model based on the social force model, introducing an active steering into basis of dynamic equation with combination behavioral decision and probability model. In AEM, detection algorithm is used to identify pedestrians or obstacles within radius provide next walking direction apply force. The obstacle avoidance core “ac...

We present an approach to enhance fault-tolerance of real-time systems through steering. Steering means external alteration of the system's behavior in response to a deviation from requirements. The steering technique is embedded into a framework of monitoring and checking (MaC). MaC allows the users to perform runtime analysis of the current execution of a system with respect to formally speci...

The steering behaviour in a driving simulator has a significant influence on a driving realism. This study investigates the influence of the complexity of a steering-system model on the subjective assessment of truck steering feel in on-centre handling. Ten subjects drove a highway task with and without lateral wind disturbance with 4 steering-system model variants. The results show that detail...

This paper evaluates EPS control strategies for improving vehicle handling and steering feel during high speed avoidance maneuver. Theoretical analysis of frequency response of steering angle and vehicle lateral acceleration relative to steering torque input is performed. Closed-loop simulation studies are also conducted by adopting a driver model to describe the human steering behavior. Based ...

A nonlinear tracking controller is presented in this paper for the haptic interface in steer-by-wire automotive systems. Specifically, the controller is designed to ensure that the steering mechanism (i.e., directional control assembly) follows the operator corn-rnanded maneuvers at the driver interface. Further, the controller provides the driver with tunable force feedback , proportional to t...

The Internet Research Task Force (IRTF) has responsibility for organizing groups to investigate research topics related to the Internet protocols, applications, and technology. IRTF activities are organized into Research Groups. This document describes the guidelines and procedures for formation and operation of IRTF Research Groups. It describes the relationship between IRTF participants, Rese...
