Automotive controllers are often first designed in a simulation environment using continuous time models of the controller and vehicle plant. Unfortunately, the controller's implementation in software and deployment onto a microcontroller has ramifications for performance and cost. In this paper, we use an automotive case study of a yaw moment controller to demonstrate that these ramifications can...
The highway entrance management systems use ramp-metering in order to control the access of the vehicles on the highway in a matter that doesn't have a negative impact on the highway vehicle traffic flow. The access is permitted on specific moments, related to the traffic values on the highway and on the entering ramp, by using a control barrier. In this article we propose a laboratory model that...
The current technology trend in automotive navigation systems is “Display Audio” devices. These are display devices that connect directly to and are controlled by the user's smartphone. However, such devices suffer problems of driver distractibility as well as problems related to differences in the life cycle of the Display Audio device and the smartphone. In this study, we discuss the state of current...
This paper presents a novel small unmanned aerial system which can operate independently and navigate using visual sensors. The basis of the system is a 600 gram quadrotor platform with sonar, inertial sensors and a camera. All processing is performed onboard the vehicle on a lightweight and powerful computer. Vehicle navigation is provided by a two part system. A Bierman Thornton extended Kalman...
This document describes the motivation, theoretical description, development, and flight test of a system that utilizes unmanned air vehicles (UAVs) and unattended ground sensors (UGSs) to detect and image intruders on a road network. The need for completely autonomous behavior drives the design of this system so that the UAV makes onboard decisions based upon inputs from off-board sensors (unattended...
In Iran, shared taxis are playing significant role in public transport. Maneuver of shared taxi through lanes in order to pick-up and drop-off passengers and asking their destinations may lead to disorder in traffic flow. In order to investigate the effect of these maneuvers (or sudden lane changing) on traffic flow, it is essential to simulate these maneuvers on the existing roads in intelligent...
To provide complete vehicle information protection mechanism, this work proposes a vehicle information security system (VISS) with self-adaptation. The VISS integrates the concept of role-based access control, so that it can support multiuser access mechanism to avoid illegal modification. Further, all the access control policies for the information are realized as hardware circuits, so that the VISS...
Intelligent driver assistance systems and new infotainment innovations cause a rapidly growing demand of computing power. To satisfy that demand, the quantity of electronic control units in cars has increased dramatically. OEMs tackle that trend by consolidating software on powerful multicore hardware platforms. However, current software solutions are mostly static and designed to run on limited platforms...
Facing the widely popular mobile phone software for taxi and the increasingly rich passengers' personalized demand, the optimization model of Taxi-Carpooling expenses is established which based on the passengers' preference, taking both taxi-driver and passengers' benefits into fully consideration. Based on the degree of satisfaction that passengers would pay for their own share, the model is made...
This paper introduces an example of real-time “big data” processing systems accelerated by field-programmable gate arrays (FPGAs), which will open up a novel design field for digital circuit engineers. Contrary to the perception that software on commodity servers dominates such large-scale processing requirements, there are various chances for utilizing hardware for the acceleration. One of the most...
The paper investigates the impact of different sampling strategies of car-following and lane-changing model parameters on traffic simulation results. The investigation considered seven possible sampling strategies including sampling parameters from independent normal distributions, which is customarily in commercial simulation software. Study results revealed that model performances in case of sampling...
Toward Autonomous Vehicles Ford is testing remote-control repositioning technology using vehiclemounted cameras and real-time streaming video. With Georgia Techowned golf carts to prove the technology, a person sitting in a remote location can access real-time video, streamed over long-term evolution, to drive the carts. The outcome could be a more affordable and effective way to share or park vehicles...
Detection of train integrity is a very important research matter affecting safety and more generally railway engineering. Actually the ETCS Level 1 and 2 provide the train integrity and localization functionalities by using track circuits and/or axle counter systems: the problem of these solutions is represented by the high cost of track circuit and axle counter installation, taking into account even...
Hardware-in-loop (HiL) simulation focuses on testing of Electronic Control Units (ECU) in virtual real time environment in order to scrutinize the behavior of controller under test. Use of HiL simulation in development process reduces time and cost involved in verification and validation of the ECU's development. Generally, HiL systems developed using dSPACE®, National Instruments® and other platforms...
Recently, quite cheap depth sensors are available, and they are intended to be used for the user interface of games. By exploiting the features of the sensors, the author has been developing various useful systems by using the depth data. In this paper, a new application of breathing rate counting system is developed by using the depth values to the surface of the body. By experimental studies, we...
Continuous Deployment is an important enabler of rapid delivery of business value and early end user feedback. While frequent code deployment is well understood, the impact of frequent change on persistent data is less understood and supported. SQL schema evolutions in particular can make it expensive to deploy a new version, and may even lead to downtime if schema changes can only be applied by blocking...
In robotics, nowadays, there is a strong evergrowing interest in executing replicable experiments to assess robots performance. This demand can't be easy fulfilled without established ad-hoc procedures to be followed. To this aim, an innovative software framework named DeepRuler is proposed. The presented software is able to design, automatically execute and evaluate highly replicable path-following...
To educate undergraduate and graduate students in the fundamentals of robotics focused engineering science, it is necessary to provide hands-on laboratory experiences that illuminate the theories and show their practical applications. Through a program of courses and real world applications it is possible to extend a students knowledge and expertise in areas of relevance and get students on the cutting...
This paper presents the design, implementation, and in-field experimentation of a “bilingual” underwater acoustic modem with multi-hop networking capabilities. The designed system supports the use of the JANUS physical coding scheme and of a proprietary one. JANUS is an open, simple and robust digital coding technology currently in process to become a NATO standard. The Applicon SeaModem has been...
