Unsettled Impacts of Integrating Automated Electric Vehicles into a Mobility-as-a-Service Ecosystem and Effects on Traditional Transportation and Ownership

International Transportation Innovation Center (ITIC)-Joachim Taiber
Tallinn University of Technology-Raivo Sell
  • Research Report
  • EPR2019004
Published 2019-12-20 by SAE International in United States
The current business model of the automotive industry is based on individual car ownership, yet new ridesharing companies such as Uber and Lyft are well capitalized to invest in large, commercially operated, on-demand mobility service vehicle fleets. Car manufacturers like Tesla want to incorporate personal car owners into part-time fleet operation by utilizing the company’s fleet service. These robotaxi fleets can be operated profitably when the technology works in a reliable manner and regulators allow driverless operation.Although Mobility-as-a-Service (MaaS) models of private and commercial vehicle fleets can complement public transportation models, they may contribute to lower public transportation ridership and thus higher subsidies per ride. This can lead to inefficiencies in the utilization of existing public transportation infrastructure. MaaS platforms can also cause a reduced reliance on parking infrastructure (e.g., street parking lanes and parking garages) which can contribute to an improvement in overall traffic flow, and a reduction in capital investment for commercial and residential real-estate development. Urban planning can be better centered around the true mobility needs of the citizens without sacrificing valuable…

VoGe: A Voice and Gesture System for Interacting with Autonomous Cars

Clemson University-Pablo Sauras-Perez, Andrea Gil, Jasprit Singh Gill, Pierluigi Pisu
ITIC-Joachim Taiber
Published 2017-03-28 by SAE International in United States
In the next 20 years fully autonomous vehicles are expected to be in the market. The advance on their development is creating paradigm shifts on different automotive related research areas. Vehicle interiors design and human vehicle interaction are evolving to enable interaction flexibility inside the cars. However, most of today’s vehicle manufacturers’ autonomous car concepts maintain the steering wheel as a control element. While this approach allows the driver to take over the vehicle route if needed, it causes a constraint in the previously mentioned interaction flexibility. Other approaches, such as the one proposed by Google, enable interaction flexibility by removing the steering wheel and accelerator and brake pedals. However, this prevents the users to take control over the vehicle route if needed, not allowing them to make on-route spontaneous decisions, such as stopping at a specific point of interest.This article presents VoGe, a human vehicle interaction system based on voice and pointing gestures that enables the user making spontaneous decisions over the route and communicate them to the car, while maintaining the interaction flexibility.…

Eco-Driving System for Energy Efficient Driving of an Electric Bus

SAE International Journal of Passenger Cars - Electronic and Electrical Systems

CU-ICAR Clemson University-Jackeline Rios-Torres, Pablo Sauras-Perez, Ruben Alfaro, Joachim Taiber, Pierluigi Pisu
  • Journal Article
  • 2015-01-0158
Published 2015-04-14 by SAE International in United States
This paper presents the design of an Eco-Driving Assistant System (EDAS) in which the main goal is to minimize the energy use of battery electric vehicles, in particular, vehicles utilized for public transportation. The system optimizes the speed profile of a real route schedule while satisfying the constraints imposed on speed and time. It includes a driver feedback and a driver scoring GUI which allows the driver improving his/her driving skills and comparing him/herself to a “theoretical perfect driver”.The system also includes a backward simulator that generates information related to the vehicle operation under the particular route to be optimized. The output information from the simulator is used as an input to the optimization algorithm. The simulator was validated using real data from a battery electric vehicle. The EDAS system was tested for three different driving profiles and energy consumption reductions of up to 30.33% were achieved.

Battery Electric Bus Simulator - A Tool for Energy Consumption Analysis

CU-ICAR Clemson University-Jackeline Rios, Pablo Sauras-Perez, Andrea Gil, Andre Lorico, Joachim Taiber, Pierluigi Pisu
Published 2014-09-30 by SAE International in United States
This paper presents the design, implementation and validation of a forward simulator for a battery electric bus, developed in MATLAB/Simulink. This simulator allows performing energy consumption analyses for different bus routes. In addition, a user can modify some parameters that affect the powertrain operation to understand their influence in the energy consumption of the bus. These analyses allow the electric bus manufacturers to adapt their powertrain designs and control strategies for different transit agencies with different routes and energy requirements.The simulator was validated using real data from a battery electric bus. The results showed a good correlation between the real and the simulated data. In particular, the absolute error between the real and the simulated State of Charge (SOC), which is one of the most important parameters for this kind of vehicles, was 3.24%.

Towards Collaboration in Engineering of Tomorrow - Building highly interactive Distributed Collaboration Platforms

BMW Group-Markus Schichtel
BMW Information Technology Research Center (ITRC)-Joachim Taiber
Published 2006-04-03 by SAE International in United States
This paper focuses on the product development process. It analyzes state-of-the-art collaboration workflows, and industry-standard collaboration tool functionalities. It then compares these with new tool and process concepts from industrial and academic research and development. New concepts of user-interaction are introduced, which will allow the linking of virtual and hardware prototypes collaboratively in a mixed-mode, for project reviews. The “virtual co-location” concept is explained based on several use-cases derived from the cross-functional development of mechatronic systems. Furthermore, based on business case analysis from real distributed development projects, it explains why there is a need in the automotive industry to further explore advanced technology solutions for collaborative product development.
