HEAVY-TRUCK DUTY CYCLE DATA
FROM REAL-WORLD DRIVING ENVIRONMENTS
Revision 3.3 Dated 03Nov05
Test Plan for Phase 1 Pilot Testing
(This Document Fulfills Milestone M2.1 and Deliverable D2.1 of the Project SOW)
Prepared by
Oak Ridge National Laboratory

Department of Energy’s Office of Freedom Car and Vehicles Systems
1.0 BACKGROUND
This Program will involve efforts to collect, analyze and archive data and information related to
heavy-truck operation in real-world highway environments over a two-year period of time. Such
data and information will be usable to support technology evaluation efforts, and provide a
means of accounting for real-world driving performance within heavy truck analyses. The
Program will be led by Oak Ridge National Laboratory, will involve two industry partners (Dana
Corporation (DANA) of Kalamazoo, MI, and Michelin Americas Research & Development
Corporation (Michelin) Greenville, SC) and will have support from Argonne National Laboratory
(ANL). Both industry partners are interested in the vehicle dynamics for real world applications
in order to validate their computer simulation models of the truck axles, tire performance, and
tire-road interface. Dana has agreed to provide access to a test vehicle for the initial phase of
the Program (Year 1), and up to ten vehicles for Phase 2 (Year 2). Both Dana and Michelin will
provide special instrumentation that will collect data of use to all partners. If DOT is also a
partner, additional driver-based behavior characteristics may also be collected.
The Program will be conducted in two phases. These phases are:
Phase 1 – Pilot Test: Design, Testing and Evaluation of a Duty Cycle Data Collection System.
Phase 2 – Field Test: Fleet Instrumentation, Data Collection and Analyses
This Test Plan will only be concerned with Phase 1 of the Program and will involve a number of
tasks that will result in an evaluated and tested data acquisition system (DAS) and sensor suite.
Phase 1 will assure that the hardware, software, and testing protocols are workable and can be
utilized in Phase 2 activities. The test will also provide experience in field data management,
which will be important factors in establishing the data repository for the field test in Phase 2.
Pilot data will be retrieved and analyzed utilizing various software including the PSAT Code.
This will be done in order to gain preliminary insights into real-world heavy truck duty cycles,
and to test the data collection, management, and handling portion of the system.
