One approach to plan and control data processing functions is to use a steering committee. This committee, composed of user, top management, and data processing representatives, is intended to bring a broad perspective to focus on systems issues. The empirical study described in this article examines the actual practices of companies in utilizing steering committees. Committee b nefits are stat...

The paper presents a cross-coupling controller for a four-wheel steering mobile robot with independently actuated steering and driving of each wheel. The aim of the controller is to minimize slippage during transient states of the vehicle control. Linear approximation of the criterion for no slippage is adopted for the design of the LQR-based cross-coupling controller of steering actuators. Dri...

An Ackerman steering linkage for short wheelbase, four-wheel vehicles has been developed. The linkage coordinates the steering angle of each wheel through a range of 180 degrees with minimal misalignment between wheels. Control of steering angles is accomplished using a single linear actuator. Control complexity is lower compared to four-wheel systems using individually controlled steering actu...

In this study, we compare the performance of three null steering techniques using uniform linear array. These techniques include Null Steering without using Phase Shifters, Null Steering by Decoupling the Real Weights and Null Steering by Decoupling the Complex Weights. The evaluation criteria of these techniques is based on the bases of different parameters i.e., null depth, main beam width, s...

Adrian Rodriguez Master Thesis Abstract A steering aid system called active steering is evaluated by simulating different driving events. The active steering solution, which is taken from a scientific paper, has been implemented in Matlab/Simulink. A vehicle model, also implemented in Matlab/Simulink, is used to form a total system and to compare the two systems: a conventional vehicle and a co...

A recursive Bayesian approach to narrowband beamforming for an uncertain steering vector of interest signal is presented. In this paper, the interference-plus-noise covariance matrix and signal power are assumed to be known. The steering vector is modeled as a complex Gaussian random vector that characterizes the level of steering vector uncertainty. Applying the Bayesian model, a recursive alg...

This paper describes an experimental study focusing onto the way drivers use the steering wheel while performing a 2D tracking task. The stimulus during this task was a steering wheel angle signal recorded in real situations involving turns and straight lines performed at about 30 km/h. The hand positions of 20 volunteers were recorded in 6 steering scenarios involving 7 road geometries using a...

We design a vehicle with a steering system made of two independently rotatable wheels on the front. We quantify the effectiveness of the steering system in the mobility and maneuverability of the vehicle running in a box containing a layer ping-pong balls with a packing density 0.8, below the random close packing value 0.84 in 2D. The steering system can reduce the resistance exerted by the jam...

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...
