Active Front Steer (AFS) has the ability to apply varying road wheel angles for the same steering wheel angle, depending on the speed of the vehicle. It achieves this by changing the steering gain dynamically and can be a useful driver aid: less steering wheel input is required at low speeds than a more traditional fixedgain steering system to achieve the same radius of turn. Should an AFS syst...

This contribution presents a friction estimator for industrial purposes which identifies Coulomb friction in a steering system. The estimator only needs a few, usually known, steering system parameters. Friction occurs on almost every mechanical system and has a negative influence on high-precision position control. This is demonstrated on a steering angle controller for highly automated drivin...

The proposed method is to recognize objects based on application of Local Steering Kernels (LSK) as Descriptors to the image patches. In order to represent the local properties of the images, patch is to be extracted where the variations occur in an image. To find the interest point, Wavelet based Salient Point detector is used. Local Steering Kernel is then applied to the resultant pixels, in ...

A null steering GPS antenna array is designed in this paper. In the proposed method, the exact full wave antenna radiation properties with the effect of mutual couplings and nearby scatterers are considered to calculate the array steering vector, precisely. Although the proposed method is not constrained by the array geometry and the antenna element specifications, a five patch antenna elements...

A shared lane keeping assistance system supports the driver in the steering task. In contrast to an autonomous system, the shared system works in parallel with the driver by applying an additional torque on the steering wheel. This means the system and the driver perform the steering task in cooperation. As the driver is still part of the control loop a driver model is required to predict the s...

This paper presents a new approach to closed-loop control of optical jitter with a new liquid crystal beam steering device. In contrast to conventional fast steering mirrors, where the laser beam is reflected of the controlled mirror surface, the transmissive liquid crystal beam steering device optically redirects the laser beam. The new device has no moving parts and requires low operating pow...

In spite of the presence of powered wheelchairs, some of the users still experience steering challenges and manoeuvring difficulties that limit their capacity of navigating effectively. For such users, steering support and assistive systems may be very necessary. To appreciate the assistance, there is need that the assistive control is adaptable to the user's steering behaviour. This paper cont...

Optical phased arrays are versatile components enabling rapid and precise beam steering. An integrated approach is followed in which a 1D optical phased array is fabricated on silicon-on-insulator. The optical phased array consists of 16 parallel grating couplers spaced 2 mum apart. Steering in one direction is done thermo-optically by means of a titanium electrode on top of the structure using...

This paper describes a conceptual model for computational program steering. By exploiting previous results attained in program monitoring, debugging, and connguration, the abstractions and mechanisms derived from this model are shown suitable for both algorithmic and human interactive steering. A characterization of existing systems for computational steering using the model's abstractions demo...

In this paper, we extend our previous model circuit for steering in C. elegans to control a more realistic biomechanical model of forward locomotion. We show that the identified steering circuit is sufficient to steer the full body during forward locomotion while only innervating a few of the anterior most neck muscles. Analysis of the sensorimotor transformation and phasic stimulation experime...
