To aid Original Equipment Manufacturers (OEM) in meeting future Real Driving Emissions (RDE) regulation criteria [1] across extended environmental conditions, a Road to Rig (R2R) whole vehicle development, calibration and verification approach, currently known as RDE Plus (RDE+), has been developed at HORIBA. In this paper, the methodologies required for replicating real RDE road tests on a chassis dynamometer are discussed in depth. These include application of robot driver for successful cycle replication and repeatability and use of HORIBA’s Multi-function Efficient Dynamic Altitude Simulation (MEDAS) system in conjunction with a temperature and humidity controlled test cell to replicate the engine, vehicle and environmental conditions. For RDE replication using a robot driver, two methods are presented.
