A Research Platform for Singapore

Individual Mobility Vehicles & Services

Overview

The working hypothesis of the area Individual Mobility Vehicles & Services (IMVS) is shared with RRT: it is to close the transport capacity gap between bus and MRT in Singapore and similar cities. While RRT is looking into the overall transport concept, IMVS is using those outputs to come up with detailed vehicle concepts to suit this new transit mode. For this we focus on different aspects of how such vehicles could be designed to suit their purpose in a better way while operating more efficiently. Research topics include the development of an efficient and modular powertrain, a new design for user interaction and methods for rapid and environmental prototyping and production. TUMCREATE will come up with an overall transport solution, to which IMVS will contribute the suitable vehicle concepts, co-developed with support from DAM, SMAT and AIDA.

Research

In the IMVS area, research focusses on mechanical, electrical and software demonstrators and (virtual) prototypes that serve as a proof-of-concept and illustrate the feasibility of the developed approaches. The planned work is separated into the four main work packages described below. These packages depend on each other and form the vehicle concepts. These concepts are designed to be modular and upgradeable, with associated scalable hardware and software architectures. They are part of the overall transportation concept developed by TUMCREATE.

Vehicle concept development

This work package starts with the analysis and identification of areas for improvement of the current transportation system. Based on these findings, new vehicle concepts will be introduced, for which requirements have to be determined depending on how these new vehicles would integrate with other modes of the existing transportation system. Simulation tools are developed to specify the defining parameters of the vehicle concepts e.g. vehicle capacity, powertrain technology, daily mileage and driving patterns for different use case scenarios.

Modular powertrain

Novel modular powertrain architectures with scalable components are being investigated, together with architecture simulation techniques, a design platform and standardized interface specifications. The motivation is to simplify prototyping by eliminating problems, which might occur when different system components are brought together. Modular powertrain systems can be suitable for various vehicle concepts.

User-Vehicle interaction

Intuitive user-vehicle interaction is crucial for the acceptance and success of new transportation solutions. Thus, the physical as well as the virtual interactions between passengers and the newly developed vehicles are investigated, evaluated and optimized. This will include the overall vehicle design and appearance as well as detail solutions such as the seating arrangements or the design of smartphone applications. User-vehicle interaction in our understanding extends the classic human-machine interface topics and rather is defined as an enabler for seamless on-demand-mobility for urban citizens.

Vehicle prototyping

The main focus of this module is to create physical demonstrators and bring the developed concepts into reality. From the engineering point of view, this will include the development of the overall vehicle package and structural design, while novel methods for manufacturing such as 3D printing will be used for prototyping.
