Case study on the tactical level of an autonomous vehicle control

R. C. Pozna Csaba Antonya Ernö Horváth

Publication Name: International Conference on Electrical Computer Communications and Mechatronics Engineering Iceccme 2021

Publication Date: 2021-10-07

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

In this paper, a case study is presented on the tactical level of autonomous vehicle control. Inspired by the human driver behavior, vehicle control is structured in a hierarchy on three levels: the strategic, the tactical, and the operational level. These are connected by specific links, and based on prior information and models, are transforming the input data from the environment into actuator commands on the various degree of freedom of the vehicle. The case study is presenting a simulation of a scenario, detailing the vehicle models with sensors, the collection of behavior, and the behavior selector.

Proposal of an Autonomous Vehicle Control Architecture

R. C. Pozna Csaba Antonya

Publication Name: Ines 2021 IEEE 25th International Conference on Intelligent Engineering Systems Proceedings

Publication Date: 2021-07-07

Volume: Unknown

Issue: Unknown

Page Range: 37-42

Description:

In this paper, a control program architecture is proposed for autonomous vehicles. This set of programs is structured in a hierarchy and it is inspired by the human driver behavior. It contains three levels connected by specific links: the strategic, the tactical, and the operational level. Autonomous vehicles and human-driven vehicles will share the roads in future transportation systems. The human-like driving behavior will allow other participants to predict the autonomous vehicle's behavior.

Issues about autonomous cars

R. C. Pozna Csaba Antonya

Publication Name: Saci 2016 11th IEEE International Symposium on Applied Computational Intelligence and Informatics Proceedings

Publication Date: 2016-07-07

Volume: Unknown

Issue: Unknown

Page Range: 13-18

Description:

The Autonomous car is a complex topic, different technical fields like: Automotive engineering, Control engineering, Informatics, Artificial Intelligence etc. are involved in solving the human driver replacement with an artificial (agent) driver. The problem is even more complicated because usually, nowadays, having and driving a car defines our lifestyle. This means that the mentioned (major) transformation is also a cultural issue. The paper will start with the mentioned cultural aspects related to a self-driving car and will continue with the big picture of the system.

Real-time representation of the human spine with absolute orientation sensors

Publication Name: 2016 14th International Conference on Control Automation Robotics and Vision Icarcv 2016

Publication Date: 2016-01-01

Page Range: Unknown

Description:

This paper presents a new algorithm for the real-time representation of a spine using a mobile device for recording and analyzing the human body posture. The measurements are based on inertial measuring units (IMU), which are providing the pitch angles of five points of a cord attached to the clothing (t-shirt or jacket). The algorithm developed for the real-time representation of the spine is based on quadratic Bézier curves defined in a reference frame attached to the first sensor from the head. The curve is obtained knowing the distances between the sensors and the measured pitch angles. The line of the spine is reconstructed with four segments of Bézier curves, meeting the requirement of continuity of the tangents. The obtained postures are compared with a normal one, identified by the medical specialist, by computing the average absolute distances between them. The recorded movement of the spine can be used for diagnosis purposes, and the real-time tracking for therapy by warning the user to correct his/her posture. The warning message is delivered with buzzers attached to the clothing by applying haptic stimuli on the back.

Parameter computation of the hand model in virtual grasping

R. C. Pozna Csaba Antonya Silviu Butnariu

Publication Name: 5th IEEE International Conference on Cognitive Infocommunications Coginfocom 2014 Proceedings

Publication Date: 2014-01-23

Volume: Unknown

Issue: Unknown

Page Range: 173-177

Description:

The aim of this paper is to identify the number of parameters of a hand model which can be computed during virtual grasping. The fingers of the user are tracked with various methods (position sensors and bending sensors) and the measured data is used to estimate the unknown parameter of the hand. An articulated hand model is constructed based on the assumption that the measured data is corrupted by noise and some of the hand's physical parameters are known. Virtual grasping and the parametric hand model are important, especially for force rendering in haptic feedback computation and to produce visually realistic results in hand-artifact interaction.
