Text Files for Traces:
	One Hertz dynamometer driving schedule trace files are at

Standard EPA 6 speed FTP and HWFET shift schedules:
	copies of these files may be found at

Other helpful files:
	FTP10HzTable.xls contains a 10 Hertz speed table for the FTP.
		UDDS followed by the first 505 seconds of the UDDS

	HWY10HzTable.xls contains a 10 Hertz speed table for the HWFET.
		HWFET followed by 15 idle seconds followed by the HWFET.

When you submit shift schedules:
	- times for shift points must match 1 Hertz CFR driving schedules linearly interpolated to 10 Hertz.
		example: the speed at t=25.3 seconds (15.08 mph) is derived by linear interpolation between
			speed point t=25.0 seconds (14.3 mph) and
			speed point t=26.0 seconds (16.9 mph)

	- time/speed shift points must match the 10 Hz drive schedule +/- 1 second.
		example: a FTP shift point at t=1394.3 seconds (15.08 mph)
			must be no lower than t=1394.2 seconds (14.82 mph)
			must be no higher than t=1394.4 (15.34 mph)


Special Guidance for the EPA75 Federal Test Procedure:
	An helpful graphic images of the FTP(Cert) is available at

	-Refer to the timeline graphic at http://www.epa.gov/oms/emisslab/methods/ftpevnts.jpg
	-Submit shift points in one file for all three FTP phases according to
		http://www.epa.gov/otaq/cert/cfeis/d7-shift.pdf
	-The FTP dynamometer driving schedules is composed of
		the first 1369 seconds of the 1372 second UDDS followed by
		the first 505 seconds of the 1372  UDDS
	-Driving Times (driver's trace scrolling time):
		The cold start phase begins at t=0 seconds and ends at t=505 seconds
		The transient phase begins at t=505 seconds and ends at t=1369 seconds
		The hot start phase begins at t=1369 seconds and ends at t=1874 seconds
	-The following schedule of comments is displayed on the driver's trace.
         Do not submit shift points or comments at these times.
		t=   0.0	(bag set #1 being filled)
		t=  15.0	(put trans in gear)
		t= 505.0	(bag set #2 being filled)
		t=1369.0	(hot soak begins, then bag 3)
		t=1384.0	(put trans in gear)
		t=1384.0	(end of driving schedule)
	-Shift schedules for the FTP are also utilized for the UDDS (LA4) and 505 drive schedules.


Special Instructions for the HWFET:
	-Submit shift points in one file  for both prep-HWFET and sampled HWFET according to
		http://www.epa.gov/otaq/cert/cfeis/d7-shift.pdf
	- The HWFET dynamometer drivingschedule is composed of
		a non-sampled vehicle warmup 765 seconds HWFET drive schedule
		followed by 15 idle seconds
		followed by a sampled 765 seconds HWFET drive schedule
	-Driving Times (driver's trace scrolling time):
		The warmup (no sample taken) phase begins at t=0 seconds and ends at t=765 seconds
		The sampled  phase begins at t=780 seconds and ends at t=1545 seconds
	-The following schedule of comments is displayed on the driver's trace.
         Do not submit shift points or comments at these times.
		t=  -8.0	(Eng on, in gear, before 0 secs)
		t= 780.0	(bag set #1 being filled)
		t=1545.0	(end of driving schedule)
	-Shift schedules for the FTP are also utilized for the UDDS (LA4) and 505 drive schedules.

 
Special Instructions for the SC03 and US06 dynamometer drive schedules
	-Submit shift points in one file  for the 594 second SC03 and US06
		http://www.epa.gov/otaq/cert/cfeis/d7-shift.pdf
	- The SC03 and US06  dynamometer drivingschedules at EPA are composed of
		a non-sampled vehicle warmup using the first 594 seconds
			of the SC03 or US06 600 second drive schedule
		followed by 96 idle seconds
		followed by a sampled using the first 594 seconds
			of the SC03 or US06 600 second drive schedule
	-Driving Times (driver's trace scrolling time):
		The warmup (no sample taken) phase begins at t=0 seconds and ends at t=594 seconds
		The pre-sample idle period begins at t=594 seconds and ends at t=1200 seconds
		The sampled  phase begins at t=1200 seconds and ends at t=1794 seconds
	-The following schedule of comments is displayed on the driver's trace.
         Do not submit shift points or comments at these times.
		t=  -8.0	(Eng on, in gear, before 0 secs)
		t= 690.0	(bag set #1 being filled)
		t=1286.0	(end of driving schedule)
