With the growing availability of Electric Vehicles, there is a significant opportunity to use battery “smart-charging” for voltage regulation. This work designs and experimentally evaluates a system for price-incentivised electric vehicle charging. The system is designed to eliminate negative impacts to the user while minimising the cost of charging and achieving a more favourable voltage behaviour...
With the growing penetration of the electric vehicles to our daily life owing to their economic and environmental benefits, there will be both opportunities and challenges to the utilities when adopting plug-in electric vehicles (PEV) to the distribution network. In this paper, a thorough analysis based on real-world project is conducted to evaluate the impact of electric vehicles infrastructure on...
Location based services is a class of computing services that uses the consumer's location data in order to personalize and enable features and services. Services include those for mapping and tracking, emergency response and disaster management and location based advertising. Of these services, location based advertising, also knows as hyperlocal marketing, accounts for the largest market share....
Driving at night is one of the leading causes of traffic related deaths. The lack of adequate light at night impairs a driver, preventing him/her from being able to judge distances between objects accurately as well as preventing a driver from recognizing various objects on the street and avoiding them. Additionally, high intensity light from the headlights of oncoming vehicles causes temporary blindness,...
The US Department of Transportation's (USDOT) Southeast Michigan Connected Vehicle Test Bed originally hosted USDOT Proof of Concept Testing (POC), starting in 2007. Following the success of the POC, the USDOT initiated the development of a Connected Vehicle Reference Implementation Architecture (CVRIA), and in 2013 began the final design and trial implementation of the CVRIA at the USDOT's Southeast...
This paper suggests an approach for providing the dynamic federations of clouds. The approach is based on risk assessment technology and implements cloud federations without consideration of identity federations. Here, for solving this problem, first of all, important factors which are capable of seriously influencing the information security level of clouds are selected and then hierarchical risk...
In order to enhance the safety of driving, we propose a vehicle road distance measurement and maintenance system (RDMMS) based on the emerging RFID systems on Roads (RSR), where RFID tags are deployed on the road surface to provide road information to the vehicle that has installed an RFID reader. RDMMS can measure the road distance between two vehicles via analyzing the information stored in the...
In this paper we describe a hybrid data and decision adaptive beam forming and processing strategy using a novel W-band (75–84 GHz) phased array architecture for automotive collision avoidance radars. We use the term ‘decision adaptive’ to denote the situation where the output of a tracking algorithm initializes the weight vector of the antenna array such that the main formed beam can be coarsely...
This paper deals with measurement and modeling of conducted and radiated emissions (CE and RE) of high-speed trains in the low-frequency range 9–150 kHz, which are mainly generated by power-electronic converters. Firstly, an experimental procedure and a post-processing method, based on the median filter, is proposed to improve procedures foreseen in current Standard IEC 62236-2. Specifically, magnetic-field...
In this work, an immunity test based on the Bulk Current Injection (BCI) test procedure is simulated, with the objective to predict the radio-frequency (RF) noise currents injected into the terminations of a CAN-bus line. To this end, an accurate model of the injection probe is combined with typical injection profiles recommended by automotive Electromagnetic Compatibility (EMC) Standards, and with...
A multiconductor-transmission-line (MTL) model of the high-voltage dc power bus of electric vehicles (composed of two shielded cables running above a metallic ground) is proposed for the prediction of the propagation of conducted electromagnetic noise up to 100 MHz. Model parameters are computed by knowing the geometry of the system and the permittivity of dielectric materials. The proposed model...
The great raise in the number of Electronic Control Units (ECUs) transmitting video flows (cameras) and networking vehicular technologies has caused a raised amount of exchanged video data on in-car network. Besides, the real-time audio and video based driver assistance systems have increased swiftly. These developments have imposed new requisites in terms of data rates, efficiency, performance, capacity,...
For the purposes of quantifying the potential impact of widespread electric vehicles charging on the UK's power distribution system, it is essential to obtain relevant statistical data on domestic vehicle usage. Since electric vehicle ownership is presently very limited, these data will inevitably be for conventional internal combustion engine vehicles, and in particular privately owned vehicles....
State of the art electric drive vehicles are one of the most encouraging automobile technologies to reduce our dependence on expensive, polluting fossil fuel based conventional vehicles. However, arises a new fear: the grid anxiety — whether the existing power grid, as it stands right now, will be able to handle the additional load put up by these vehicles. In this work, actual transportation statistics,...
The drivetrain characteristics of electrically assisted, tricycle human powered vehicles are the subject of this paper. The two configurations of the vehicle that appear commercially, delta and tad-pole, are studied regarding to the impact of the electrical drivetrain to their steering behavior. For this purpose, two corresponding tricycles, constructed at the premises of the Alexander Technological...
