SIMULATION FOR VEHICLE-TO-VEHICLE AND VEHICLE-TO-GRID RESOURCE SHARING ANALYSIS2024-01-344411/15/2024
ABSTRACT A simulation capable of modeling grid-tied electrical systems, vehicle-to-grid (V2G) and vehicle-to-vehicle(V2V) resource sharing was developed within the MATLAB/Simulink environment. Using the steady state admittance matrix approach, the unknown currents and voltages within the network are determined at each time step. This eliminates the need for states associated with the distributed system. Each vehicle has two dynamic states: (1) stored energy and (2) fuel consumed while the generators have only a single fuel consumed state. One of its potential uses is to assess the sensitivity of fuel consumption with respect to the control system parameters used to maintain a vehicle-centric bus voltage under dynamic loading conditions.

Arrangement and Control Method of Cooperative Vehicle Platoon2021-01-011304/06/2021
With the development of cellular communication technology and for the sake of reducing drag resistance, the multi-lane platoon technology will be more prosperous in the future. In this article, the cooperative vehicle platoon method on the public road is represented. The method’s architecture is mainly composed of the following parts: decision-making, path planning and control command generation. The decision-making uses the finite state machine to make decision and judgment on the cooperative lane change of vehicles, and starts to execute the lane change step when the lane change requirements are met. In terms of path planning, with the goal of ensuring comfort, the continuity of the vehicle state and no collision between vehicles, a fifth-order polynomial is used to fit every vehicle trajectory. In terms of control command generation module, a model predictive control algorithm is used to solve the multi-vehicle centralized optimization control problem. We use the two DOF vehicle

As the world turns to C-V2X, Europe picks WiFi Vehicle-to-everything (V2X) communications is a relatively straightforward and inexpensive technology that has the potential to reduce crashes by improving driver situational awareness. Compared to the automated-driving technology that most of the industry is rushing to develop, V2X is cheap and can even be retrofitted to existing vehicles. Yet despite these and other benefits, V2X has not yet been rolled out globally amid a new technology-standards battle.

SAE STANDARDS NEWS19AUTP04_0704/01/2019
SAE's Global Ground Vehicle Standards (GVS) staff and committee members have a busy schedule lined up for this year's SAE World Congress Experience (WCX) in Detroit. The GVS team will meet and work on activities that include advanced technologies of automated driver-assistance systems (ADAS), autonomous vehicles, shared mobility, V2X, cyber security, and human factors, in addition to dozens of “traditional” subject areas. The GVS staff is implementing new methods to expedite the standards development process for these increasingly complex engineering systems and rapid technology advancements, without violating fundamental rules of a consensus-based open process needed to ensure stakeholder participation and adoption.

Transportation-infrastructure expert Kirk Steudle reflects on the rapid progress toward the connected-AV future and the challenges ahead. In the auto industry, mechanical and electrical engineers work from the tire up. Civil engineers work from the tire down,” quips Kirk Steudle. “And although it's taken a while for both to understand each other's jargon, the connected-and-autonomous vehicle is forcing them all together-to solve problems for society's mobility.” Steudle, a registered professional engineer, has been at the vehicle-to-road nexus his entire career. Last October he retired as director of the Michigan Dept. of Transportation where, among many achievements, his leadership helped put the state and its core industry in the vanguard of connected-car and AV-related developments, testing, and infrastructure standards. During his final year at MDoT, he also served as interim CEO of the American Center for Mobility, the new 500-acre AV proving ground and test center near Ann Arbor.

Grid-Tied Single-Phase Bi-Directional PEV Charging/Discharging Control2016-01-015904/05/2016
This paper studies the bi-directional power flow control between Plug-in Electric Vehicles (PEVs) and an electrical grid. A grid-tied charging system that enables both Grid-to-Vehicle (G2V) and Vehicle-to-Grid (V2G) charging/discharging is modeled using SimPowerSystems in Matlab/Simulink environment. A bi-directional AC-DC converter and a bi-directional DC-DC buck-boost converter are integrated to charge and discharge PEV batteries. For AC-DC converter control, Predictive Current Control (PCC) strategy is employed to enable grid current to reach a reference current after one modulation period. In addition, Phase Lock Loop (PLL) and a band-stop filter are designed to lock the grid voltage phase and reduce harmonics. Bi-directional power flow is realized by controlling the mode of the DC-DC converter. Simulation tests are conducted to evaluate the performance of this bi-directional charging system. The simulation results show that the integrated PCC, PLL, and band-stop filter can achieve

Experimental Demonstration of Smart Charging and Vehicle-to-Home Technologies for Plugin Electric Vehicles Coordinated with Home Energy Management Systems for Automated Demand Response2016-01-016004/05/2016
In this paper, we consider smart charging and vehicle-to-home (V2H) technologies for plugin electric vehicles coordinated with home energy management systems (HEMS) for automated demand response. In this system, plugin electric vehicles automatically react to demand response events with or without HEMS’s coordination, while vehicles are charged and discharged (i.e., V2H) in appropriate time slots by taking into account demand response events, time-ofuse rate information, and users’ vehicle usage plan. We introduce three approaches on home energy management: centralized energy control, distributed energy control, and coordinated energy control. We implemented smart charging and V2H systems by employing two sets of standardized communication protocols: one using OpenADR 2.0b, SEP 2.0, and SAE standards and the other using OpenADR 2.0b, ECHONET Lite, and ISO/IEC 15118. We show that the both communication protocol sets enable the same energy management by adding some properties and class

Digital Communications for Plug-in Electric VehiclesJ2931/1_201201 (Historical)01/24/2012
This SAE Information Report SAE J2931 establishes the requirements for digital communication between Plug-In Vehicles (PEV), the Electric Vehicle Supply Equipment (EVSE) and the utility or service provider, Energy Services Interface (ESI), Advanced Metering Infrastructure (AMI) and Home Area Network (HAN). This is the first version of this document and completes the step 1 effort that captures the initial objectives of the SAE task force. The intent of step 1 was to record as much information on "what we think works" and publish. The effort continues however, to step 2 that allows public review for additional comments and viewpoints, while the task force also continues additional testing and early implementation. Results of the step 2 effort will then be incorporated into updates of this document and lead to a republished version. The SAE J2931 family of documents has been organized into several "slash" subsections: This document, SAE J2931/1, defines architecture and general

Communicating 2020 styleOFHAUG09_0508/01/2009
Executive Viewpoints-Vehicle Development Insights from Industry: Off-Highway 2020 and Beyond-Communicating 2020 style. People are all looking forward to the day when digital information is delivered at lightning speed, anytime and anywhere they happen to be. As information and data becomes more available to individuals, it is integrated into the fabric of daily life, helping to improve personal convenience and productivity. The need for continuous communication is even truer for businesses, as real-time information can also improve asset utilization and productivity. When we think of “communication” we typically think of talking to a colleague, a friend, or a family member. But, as our knowledge has increased, new technology has been developed that allows machines to “talk” to other machines. That kind of communication is known as machine-to-machine (M2M) communication and is enabled by telematics.
