kinematic synthesis of a trailing six-member mechanism has been carried out to achieve five precision points of an automotive steering mechanism. the inner wheel can be rotated up to forty five degrees with fair accuracy. results show that the divergent end behavior of ackermann steering mechanism has been overcome by the present mechanism. the work is similar to earlier work by the present aut...

Steer-by-wire is the electrical steering systems on vehicles that are expected with the development of an optimal control system can improve the dynamic performance of the vehicle. This paper aims to optimize the control systems, namely Fuzzy Logic Control (FLC) and the Proportional, Integral and Derivative (PID) control on the vehicle steering system using Imperialist Competitive Algorithm (IC...

automation of tractors due to their widespread use in different sectors e.g. agriculture, construction and industry have been seriously considered by researchers. in this study a tele-steering system for tractor was designed and constructed to controling and steering so the operator can control the tractor even far away from the stressful condition of tractor cab, . a cctv camera and an electri...

This paper investigates the relationship between “error feedback” (when tracking or trajectory errors are made) and user performance in steering tasks. We conducted experiments to examine feedback presented as visual, auditory and tactile modalities, both individually and in combinations. The results indicate that feedback significantly affects the accuracy of steering tasks but not the movemen...

This study examined age related decrements in the use of optical flow and landmark information for the control of steering. Older and younger drivers viewed computer generated displays simulating vehicle motion through a random dot ground plane scene. The horizontal position of the driver was perturbed according a sum of sines function and the driver had to keep steering straight (resembling th...

Drivers aim to maintain their vehicle within a number of individual situated safety margins. Safety margin violations are characterized by rapid strong corrective steering. Steering entropy was introduced to quantify drivers’ efforts to maintain their lateral safety margins. In the original steering entropy, several computational assumptions were made. The objective is to scrutinize and motivat...

Advanced Vehicle Control Systems (AVCS) is a key technology for Intelligent Transportation System (ITS) and Intelligent Vehicle Control System (IVCS). AVCS involves automatic steering, acceleration and braking control of fully autonomous vehicles. The unmanned control of the steering wheel is one of the most important challenges faced by the researchers. This paper proposes control architecture...

This paper describes an analytical method for modeling the positioning error of a robotic vehicle and examines how the metric of this error can be used to compare the geometries of various steering configuration. Positioning error can be caused by many factors stemming from the robot’s hardware and software configurations and the interaction between the robot and its environment. A slip motion ...
