A driving cycle is a set of second-by-second velocities that the simulated vehicle is to attain during the simulation. There are many standard driving cycles used for testing road vehicles for fuel economy and other purposes. Several are provided below for use with the Wheels online road load simulation.
Descriptions and data (except for constant speed cycles) are taken from the US EPA Dynamometer Driver's Aid web site.
UDDS - Urban Dynamometer Driving Schedule
The EPA Urban Dynamometer Driving Schedule (UDDS) is commonly called the "LA4" or "the city test" and represents city driving conditions. It is used for light duty vehicle testing. The UN/ECE Regulation 53 refers to the EPA UDDS as the "Test Equivalent to the Type 1 Test (verifying emissions after a cold start)".
Duration 1369 sec
Distance 7.45 mi
Ave speed 19.59 mi/hr
Top speed 56.7 mi/hr
LA92 - Unified Dynamometer Driving Schedule
The Air Resources Board LA92 Unified Dynamometer Driving Schedule, often called the Unified driving schedule, was developed as an emission inventory improvement tool. Compared to the FTP, the LA92 has a higher top speed, a higher average speed, less idle time, fewer stops per mile, and a higher maximum rate of acceleration.
Duration 1435 sec
Distance 9.82 mi
Ave speed 24.61 mi/hr
Top speed 67.2 mi/hr
HFET - Highway Fuel Economy Test
The Highway Fuel Economy Test (HWFET) represents highway driving conditions under 60 mph.
Duration 765 sec
Distance 10.26 mi
Ave speed 48.3 mi/hr
Top speed 59.9 mi/hr
FTP - Federal Test Procedure
The Federal Test Procedure (FTP) is composed of the UDDS followed by the first 505 seconds of the UDDS. It is often called the EPA75.
Duration 1874 sec
Distance 11.04 mi
Ave speed 21.2 mi/hr
Top speed 56.7 mi/hr
US06 - Supplemental FTP
The US06 is a high acceleration aggressive driving schedule that is often identified as the "Supplemental FTP" driving schedule.
Duration 596 sec
Distance 8.01 mi
Ave speed 48.37 mi/hr
Top speed 80.3 mi/hr
NYCC - New York City Cycle
The New York City Cycle (NYCC) features low speed stop-and-go traffic conditions.
Duration 598 sec
Distance 1.18 mi
Ave speed 7.1 mi/hr
Top speed 27.7 mi/hr
ECE-ELEM - UN/ECE Elementary Urban Cycle
The UN/ECE Elementary Urban Cycle (ECE-ELEM) is Part 1 of the ECE Type 1 Test.
Duration 195 sec
Distance 0.994 km
Ave speed 18.35 km/hr
Top speed 50 km/hr
ECE-EU - UN/ECE Extra-Urban Cycle
The UN/ECE Extra-Urban Cycle is Part 2 of the ECE Type 1 Test.
Duration 400 sec
Distance 6.955 km
Ave speed 62.59 km/hr
Top speed 120 km/hr
ECE-EULP - UN/ECE Extra-Urban (Low Powered Vehicles) Cycle
The UN/ECE Extra-Urban (Low Powered Vehicles) Cycle (ECE-EULP) is an alternative for Low-Powered Vehicles for Part 2 of the ECE Type 1 Test.
Duration 400 sec
Distance 6.609 km
Ave speed 59.48 km/hr
Top speed 90 km/hr
30 mi/hr Cruise
This cycle begins with a gentle acceleration to 30 miles per hour, and continues at this velocity until gently decelerating to zero.
Duration 600 sec
Distance 4.725 mi
60 mi/hr Cruise
This cycle begins with a gentle acceleration to 60 miles per hour, and continues at this velocity until gently decelerating to zero.
Duration 600 sec
Distance 9.42 mi
