Vehicle Drive Cycle Analysis for Fuel Economy and Emissions

This class is being offered as a special free training to all South American GT users.  It starts 2 days following the South American GT-SUITE Conference at the MAHLE Technical Center.

This two day course is intended for those interested in developing vehicle models in GT-SUITE.  The course will focus on the construction of basic vehicle models that can be used for fuel economy analysis, tractive performance studies, and driving cycle emission optimization (in context of PROCONVE L5 and L6 regulations). This course is also applicable to engineers who want to develop vehicle models as a subsystem in larger integrated simulations (e.g. vehicle thermal management models). Integration with other libaries of GT-SUITE will be showcased.  The following topics will be covered in this course:

Introductory Concepts of GT-SUITE:

• Model Setup-initialization, parameter sweeps, Optimization/Design of Experiments
  
• Post-processing (GT-POST)
  
• Subassemblies: internal, external, encryption of subassemblies
  
• GT-SUITE 1-D mechanics concepts and application to vehicle drivetrains

The following vehicle modeling topics will be included:

• Mapped Engine Model
  
• Discrete transmissions and shifting strategies, CVTs
  
• Other driveline elements (clutch, torque converter, differential)
  
• Tire Modeling
  
• Vehicle
  
• Acceleration Studies (0-100 kph, 1/4 mile, etc.)
  
• Driver Controls (for Automatic or Manual Transmissions)
  
• Driving Cycle Analysis (with Model Based Targeting Controller)
  
• Alternative Analysis Modes (Kinematic and Static calculations)
  
• Vehicle gradability analysis including on-grade launching
  
• PROCONVE L6 Emission Standards and Drive Cycle Optimization

If time permits, additional and/or specialized topics may be covered in a general manner, through discussion of application examples. Possible topics (to be selected by the participants) are:

• Detailed Transmission Modeling
  
• Drivetrain Torsional Analysis and Driveability
  
• Advanced Control Strategies
  
• Integrated Simulations (e.g. drivetrain torsional vibrations with detailed engine)
  
• Other user-defined
