MEMORANDUM
SUBJECT:	Ex parte meeting with Hino Motors, Ltd.
FROM:		Maurice Hicks, NHTSA
TO:		Docket No. NHTSA-2010-0079
This memorandum documents a meeting held on November 19, 2010 between Hino, EPA, and DOT regarding the proposed fuel efficiency and greenhouse gas standards for medium- and heavy-duty vehicles and engines for model years 2014-2018.  The attendees included:
Hino: Seiichi Yamaguchi, Yoshihide Takenaka, Akira Harada, Chikako Sato, Richard Gezelle 
EPA: Byron Bunker, Cleophas Jackson, Chien Sze, Soduk Lee, and Houshun Zhang  
NHTSA/DOT: James Tamm, Gregory Powell, and Maurice Hicks
The following topics were discussed during the meeting:
HINO requested a meeting with the agencies to discuss the possibility of using improved approaches for certifying the GHG emissions and fuel consumption of hybrid heavy-duty trucks.  During the meeting, Hino provided a detailed overview on hardware in the loop simulation (HILS) certification.  HINO also discussed the possibility of HILS evaluation by the agencies. Hino offered to provide a copy of the software and guidelines to the agencies.   
HINO stated that HILS could address an issue with the current chassis dyno test:  the duty cycles do not properly evaluate the hybrid system benefit.  According to HINO, using modeling is a more feasible approach to evaluating hybrid system benefits in heavy duty trucks.   The HILS model is one alternative approach that can be used for evaluating hybrid trucks and is currently under consideration by the industry.  HINO requested that the agencies consider the HILS model as the industry-wide test method for evaluating HD hybrid vehicles.  The HILS model is currently being evaluated for its uses as a part of the WP29 GTR on heavy duty truck fuel efficiency.  
The agencies agreed to consider the above requests.
