  • Modeling and development of E85 fueled two-mode hybrid electric vehicle
    Kunal Patil, Stephen Bayne, Timothy T. Maxwell
    SAE Technical Papers, 2013
    Texas Tech University (TTU) was one of sixteen universities competing in EcoCAR:-The Next Challenge competition. It is a three year collegiate advanced vehicle technology competition where teams are challenged to re-engineer a General Motors(GM) donated vehicle to achieve improved fuel economy and reduced emissions while maintaining consumer acceptability in the areas of stock performance, utility and safety. Two-mode hybrid which is an electrically variable transmission was selected as the Texas Tech team's architecture. The first year of the competition emphasized vehicle design through Powertrain System Analysis Toolkit (PSAT) software. The vehicle design parameters were established through vehicle technical specifications(VTS), development of software-in-the-loop (SIL) and hardware in-the-loop (HIL) techniques, rapid control system prototyping and components selection and sizing. These first year activities were continued for the vehicle development and refinement in subsequent years of the competition. This paper describes the design procedure of SIL, HIL and rapid prototyping. The Mathworks Simulink, SimDriveline, SimScape and Stateflow software provided an environment for modeling selected architecture and powertrain components. Once the model was verified HIL testing was performed with the use of National Instruments PXI and dSpace MicroAutoBox (MABX). In this way the process moved from mathematical models to lab based tests with HIL. A realistic vehicle propulsion controller was developed by moving to in-vehicle testing of the vehicles' on board software.
  • Hybrid vehicle model development using ASM-AMESim-Simscape co-simulation for real-time HIL applications
    Kunal Patil, Sisay Kefyalew Molla, Tino Schulze
    SAE Technical Papers, 2012
    Hardware-in-the-loop (HIL) simulation is a real-time testing process that has been proven indispensable for the modern vehicle dynamics, powertrain, chassis and body systems electronic controls development. The high quality standards and robustness of the control algorithms can only be met by means of detailed vehicle plant simulation models. In the last few years, several efforts have been made to develop detailed plant models. Several tools for the vehicle modeling are available in the market and each tool has different and distinct advantages. This paper addresses ways that dSPACE Automotive Simulation Models (ASM) can support the model-based development processes. Additional modern software tools that were used in connection with the ASM are LMS AMESim and Mathworks SimDriveline (of Simscape). ASM is an open Matlab/Simulink model environment used for offline PC based simulation and online real-time platform HIL testing. The combinations of system models from different suppliers typically require significant adaptation effort. dSPACE's ASM are ideally adapted to dSPACE hardware-in-the-loop simulators with real time capability whereas the AMESim environment requires a special procedure to make it compliant with dSPACE real-time hardware. This paper describes how AMESim vehicle dynamics, SimDriveline automatic transmission models and ASM parallel hybrid vehicle models are integrated for a dSPACE HIL real-time simulation environment.
  • Vehicle development process for EcoCAR: The next challenge competition
    Kunal Patil, Timothy Maxwell, Stephen Bayne, Richard Gale
    2010 IEEE Vehicle Power and Propulsion Conference Vppc 2010, 2010
    Present work investigates development of the vehicle design in the Texas Tech University EcoCAR program with industry standard vehicle development process (VDP). The three different architectures considered are fuel cell, GM two-mode hybrid and belt alternator/starter system (BAS+). The design process started from the architecture selection with the use of PSAT software. Based on results, best choice of vehicle architecture among the three considered is two-mode hybrid. With Matlab/Simulink environment vehicle model is developed. The plant model and controller model is tested with software-in-loop (SIL) and hardware-in-loop (HIL) simulations. The testing of this stage is done with NI PXI and dSPACE MicroAutoBox.
  • Selection of vehicle architecture for EcoCAR competition using axiomatic design principles
    Derrick Tate, Timothy T. Maxwell, Bharatendra S. Sharma, Kunal Patil
    Proceedings of the ASME Design Engineering Technical Conference, 2010
    Axiomatic design (AD) techniques have not previously been applied in designing the overall architecture of an automobile. The present work investigates use of axiomatic design concepts for vehicle design in the Texas Tech University Eco-CAR program. The three different architectures considered are fuel cell, two-mode hybrid, and belt alternator/starter system (BAS+). The objective in using axiomatic design methods is to choose an architecture for the EcoCAR competition vehicle that follows the principles of axiomatic design, and in turn, should prove to be the best choice of vehicle architecture among the three considered. Function means trees (FMT) and design matrices (DM) are constructed for each of the architectures and are used in deciding whether the architecture is a coupled, uncoupled, or decoupled design per the independence axiom. The choice is supported by means of simulation results obtained for each architecture. Finally, a two-mode hybrid architecture is selected based on the use of axiomatic design and the simulation results.
  • Hardware-in-the-loop testing of GM two-mode hybrid electric vehicle
    Timothy Maxwell, Kunal Patil, Stephen Bayne, Richard Gale
    2010 IEEE 12th Workshop on Control and Modeling for Power Electronics COMPEL 2010, 2010
    This paper presents Hardware-in loop (HIL) testing for GM two-mode hybrid. First Modeling and simulation of GM two-mode hybrid using model based design (MBD) process is performed. HIL testing is performed using dSpace MicroAutoBox (MABX) and National Instruments PXI. The control strategy compiled code is uploaded to MABX using ControlDesk software and the corresponding plant model is transferred to PXI using NI Veristand software. This work is part of EcoCAR competition by the Texas Tech University. EcoCAR: The Next Challenge is a vehicle engineering competition organized by the US Department of Energy (DOE) and General Motors (GM).
