Additional information on RDE+
Drawing on its unparalleled expertise in emissions measurement development, RDE+ sees HORIBA bring together its established hardware and software portfolio and interface it with industry-standard virtual tools, such as vehicle simulation and environment simulation (IPG CarMaker), to enable physical testing to be controlled by virtual modelling.
During the process, a computer model of a vehicle driving in a virtual environment is connected directly to a real engine on an automated transient testbed with environmental emulation capability. The engine is controlled by the simulation and responds as if it were being driven around the virtual test route. In this way, real-world emissions are measured from virtually generated RDE scenarios; effectively bringing together the best of both the virtual and real worlds.
This approach offers multiple benefits. Typically, the ‘real-world’ element of the RDE process entails an infinite number of scenarios that can take months or years to develop, the results of which can be further complicated by inaccuracies in equipment, alongside testing inconsistencies such as road characteristics, weather conditions or even driving style. Add to the equation the fact that testing in the necessary conditions typically requires engineering teams to travel to different locations, and for weeks on end; and the result is an incredibly labour-intensive and costly exercise.
Virtualising this physical process and bringing it into the lab negates such discrepancies and issues by providing an almost infinite number of scenarios on one site which can be tested 24 hours a day, supported with unparalleled control to ensure true like-for-like results every time. Working in this way, manufacturers are able to test designs quickly at every stage of the design process to ensure compliance, thereby reducing prototype programme costs and the risk of non-compliance near to market launch. Moreover, by validating Tier 1 systems, fuels and lubes under real world conditions in the lab, it is expected that total product cost can be reduced along with warranty provisions and in-service compliance issues.
