Design, Modeling And Control Of Steering And Braking For An Urban Electric Vehicle

Maciua, Dragos
1996

This report describes research which involved the design modification, modeling and control of automatic steering and braking systems for an urban electric vehicle. The vehicle is equipped with four-wheel independent drive, four-wheel independent braking and four-wheel steering. Control algorithms were developed for steering and braking. Simulation results show the feasibility of the algorithms.

Achieving Zero-Emission Mobility: The Role of Innovative Electric Vehicle Companies

Argote, Juan
Lee, Albert
Hernandez, Maribel
2016

On April 28, 2016, UCCONNECT hosted a symposium in Berkeley, CA on Achieving Zero-Emission Mobility: The Role of Innovative Electric Vehicle Companies. The symposium provided a platform for innovative and trendsetting electric vehicle (EV) companies to explain their latest business models and show how they can add value and contribute to the national dialogue on the transformation needed to achieve zero-emission transportation. Focus was also placed on identifying strategies that could potentially broaden the clean-transportation conversion by increasing “zero-emission vehicle” (ZEV)...

Strategic Charging Infrastructure Deployment for Electric Vehicles

Shen, Max
Li, Meng
He, Fang
Jia, Yinghao
2016

Electric vehicles (EV) are promoted as a foreseeable future vehicle technology to reduce dependence on fossil fuels and greenhouse gas emissions associated with conventional vehicles. This paper proposes a data-driven approach to improving the electrification rate of the vehicle miles traveled (VMT) by a taxi fleet in Beijing. Specifically, based on the gathered real-time vehicle trajectory data of 46,765 taxis in Beijing, we conduct time-series simulations to derive insight for the public charging station deployment plan, including the locations of public charging stations, the number of...

Charging up the Central Coast: Policy solutions to improve electric vehicle charging access in Watsonville

Sarode, Shruti, MS
Segal, Katie, MPP
Elkind, Ethan, JD
2023

California's goal to eliminate internal combustion engine sales by 2035 poses challenges for lower- and moderate-income residents, hindering their access to electric vehicles (EVs). Barriers include limited EV charging stations, exacerbated by lower home ownership and inadequate grid infrastructure in lower-income communities. To address this, UC Berkeley School of Law's Center for Law, Energy & the Environment (CLEE) partnered with the City of Watsonville. Due to its location, demographics, and ambitious policy goals, Watsonville represents a potential model and case study for...

A Report on the Future of Electric Aviation

Seeley, Brien A., MD
Seeley, Damon
Raka, Jasenka, PhD
2020

UC Berkeley has long been known as the home of important societal movements. In early October 2019, the electric aircraft movement came to UC Berkeley (UCB) courtesy of UCB’s Institute for Transportation Studies (ITS) and the College of Engineering. At what some have called the “Woodstock of Aviation”—the Sustainable Aviation Symposium (SAS) convened leaders of that movement from across the globe for two full days in UC’s Pauley Ballroom to explore how to solve important societal-enviro-economic issues in transportation with breakthroughs and innovations in high-tech physics, chemistry and...

Supercharged? Electricity Demand and the Electrification of Transportation in California

Burlig, Fiona, PhD
Bushnell, James PhD
Rapson, David PhD
Wolfram, Catherine PhD
2020

The rapid electrification of the transportation fleet in California raises important questions about the reliability, cost, and environmental implications for the electric grid. A crucial first element to understanding these implications is an accurate picture of the extent and timing of residential electricity use devoted to EVs. Although California is now home to over 650,000 electric vehicles (EVs), less than 5% of these vehicles are charged at home using a meter dedicated to EV use. This means that state policy has had to rely upon very incomplete data on residential charging use. This...

Benchmarking “Smart City” Technology Adoption in California: An Innovative Web Platform for Exploring New Data and Tracking Adoption

2021

In recent years, “smart city” technologies have emerged that allow cities, counties, and other agencies to manage their infrastructure assets more effectively, make their services more accessible to the public, and allow citizens to interface with new web-and mobile-based alternative service providers. This project developed an innovative user-friendly web interface for local and state policymakers that tracks and displays information on the adoption of such technologies in California across the policing, transportation, and water and wastewater sectors for a comprehensive set of local...

Vehicle Manufacturing Futures in Transportation Life-cycle Assessment

Chester, Mikhail
Horvath, Arpad
2011

Vehicle manufacturing effects are critical life-cycle components in the total costs of vehicle travel and future manufacturing processes should be evaluated for travel forecasts. With efforts to introduce lightweight materials, increased fuel economy, and new technologies such as electric vehicles, understanding the energy and environmental effects of these expected vehicles is critical. Current vehicle manufacturing energy use and greenhouse gas emissions are summarized from existing research for passenger (conventional gasoline vehicles, hybrid electric vehicles, aircraft, high-speed...

Where are Private “Smart City” Transportation Technologies Concentrated in California?

2022

In recent years, “smart city” information and communication technologies have proliferated. For local government agencies, procuring and introducing these technologies offers the possibility to manage infrastructure assets more effectively, plan for preventive maintenance, and disseminate schedules and information about transit and other services. Many of these technologies are deployed by private firms in the context of local regulations and government-sponsored incentives. In the transportation sector, examples of “smart city” technology services provided by private firms include:...
