This research derives, implements, tunes and compares selected path tracking methods for controlling a car-like robot along a predetermined path. The scope includes commonly used methods found in practice as well as some theoretical methods found in various literature from other areas of research. This work reviews literature and identifies important path tracking models and control algorithms ...

This paper describes new wireless networking technology and its applications to off-road equipment. We present an overview of current wireless networking equipment as well as a description of a commercially available voice recognition package. We then demonstrate several examples of the use of wireless networking for control and automation on an agricultural platform. These examples include tel...

Conventional approach to the virtual prototyping of the steering system provides analysis and simulation tools which generate numerical results in the form of plots, charts tables or animation. The interpretation of the numerical results is not done naturally, no clear conclusion can be drawn considering the steering comfort and the task needs a skillful engineer. This paper proposes a novel ap...

The present study has established equal sensation curves for steering wheel hand-arm rotational vibration. Psychophysical response tests of 20 participants were performed in a steering wheel rotational vibration simulator using the category-ratio Borg CR10 scale procedure for direct estimation of perceived vibration intensity. The test stimuli used were sinusoidal vibrations at 22 third octave ...

Purpose – The purpose of this paper is to provide a clustering approach to segment supply chain partners in the automobile industry and prioritize services offered by third party logistics service (3PL) providers. Design/methodology/approach – In total, 98 automobile and auto-parts manufacturers are surveyed to identify service needs, preferences, and outsourcing commitments. By applying a two-...

This study investigated the human fatigue caused by automobile steering wheel vibration. Discomfort data was collected from 15 subjects using a steering wheel vibration bench. A rigid wheel was used to apply sinusoidal rotational excitation of 0.08 m/s and 0.1 m/s amplitude at test frequencies of 4, 8, 16 and 32 Hz. Human discomfort was quantified after periods of 1, 5 and 10 minutes by means o...

As awareness of shipping’s impact on the environment grows, increasing attention is being paid to “operational lubricant discharges”. Such leakage of lubricating oil, in the course of normal operations, may occur both from underwater equipment (sterntubes, controllable pitch propellers, thrusters and pods, steering gear, stabilisers) and from above the waterline equipment (such as cranes, davit...

An automatic parking system provides convenience for drivers by automatically finding free parking spaces and steering automobiles toward them. This paper proposes a vision-based free parking space detection system. The proposed method consists of two stages. First, the automobile rearview is three-dimensionally reconstructed using the optical flow-based method. The metric information is recove...

BACKGROUND This study seeks to increase clinical operational efficiency and accelerator beam consistency by retrospectively investigating the application of statistical process control (SPC) to linear accelerator beam steering parameters to determine the utility of such a methodology in detecting changes prior to equipment failure (interlocks actuated). METHODS Steering coil currents (SCC) fo...

This paper explores the possibility of combining solid state accelerometers with a low resolution position sensor to provide clean estimates of automobile handwheel position, velocity and acceleration for use in force feedback. Typically determining the acceleration and velocity of the handwheel requires differentiating a position sensor such as an encoder or potentiometer. Unless expensive hig...
