Session Description and Agenda

DESCRIPTION

The idea of fixed duty cycles for emissions and energy testing will be obsolete with the introduction of CAVs, but what might updated testing schema be? In this workshop, we will start with an introduction to historical energy-focused test processes. This will be followed by a panel discussion about trades between virtual, lab, and on-road testing, as well as about the complexity of scenario-based testing. Participants will then form groups where each group must create a test schema for vehicles with different levels of automation and/or connectivity. Developed notional test schemas will be shared at the end of the session and distributed afterwards to interested parties.

AGENDA

!!!!! THIS WILL BE AN INTERACTIVE WORKSHOP - PLEASE BRING YOUR LAPTOPS !!!!!
---------------------------------------------------------------------------------------------------------------------------
15 mins: Intro comments, presentation to set baseline understanding: general test methods now. (Mike Duoba)

25 mins: Panelists introduce themselves and each give 5 minute overview of their approach/product.

60 mins: Panel discussion (Kevin Stutenberg)
• Test supplier: Leo Breton - Horiba, Joshua Orlando - AVL
• Simulation: Jace Allen - Dspace
• Standards development organization: Mike Duoba - Argonne National Laboratory
• Academia/Research: Bo Chen - Michigan Technical University, Michael Brown - Southwest Research Institute

Potential discussion topics:
• Consider the role of virtual versus lab versus limited road testing versus periodic testing throughout vehicle lifetime
• How does cost change this calculus?
• Learn about nuances associated with scenario-based energy testing
• What are the gaps?
• What do we need to standardize? What shouldn’t be standardized and should be random?
• How do we aggregate statistical features of roads?
• Local roads, arterials, freeways
• Road grade, speed limits, road curvature
• What is the role of infrastructure?
• Should this be feature-driven?
• What about all the driving when you’re just moving in a lane, no specific features associated?
• Discuss whether software updates could change an assessment (and if so, how often might assessments need to be performed?)

60 mins: Breakout session (Danielle Chou)
• Using intro presentation handout, participants choose a group to create notional tests

20 mins: Re-convene, breakout groups brief summary results

Session Objectives

• Consider the role of virtual versus lab versus on-road testing
• Learn about nuances associated with scenario-based energy testing
• Discuss whether software updates could change an assessment (and if so, how often might assessments need to be performed?)
• Exchange ideas about how to identify/formulate scenarios (different self-identified ODDs, randomness, etc.)
• Participants will create, then share their notional test schema for vehicles of differing levels of automation and/or connectivity.
