Development of a Simulation Tool to Calculate Fuel Consumption and Emissions of Vehicles Operating in Dynamic Conditions 2004-01-1873
Within the European project Decade a vehicle level simulation tool was developed for the simulation of fuel consumption and emissions for real traffic transient vehicle operation. The specific task in the project was to include a method for calculating dynamic emissions, and thereby reaching higher accuracy than traditional emission simulation modeling. The final simulation tool, which is called VeTESS (Vehicle Transient Emissions Simulation Software), calculates emissions and fuel consumption on a second-by-second basis for a specific vehicle on a given speed profile. It is based on a detailed calculation of the engine power required to drive a given vehicle over any particular route. This includes the rapidly changing (transient) demands placed on the engine, an area that has proved an obstacle to accurate simulation in the past. This paper describes the approach used to obtain dynamic emission maps, and the validation of the simulation tool based on a large number of measurements.
