Scania is a world-leading provider of transport solutions. Together with our partners and customers we are driving the shift towards a sustainable transport system. In 2017, we delivered 82 500 trucks, 8 300 buses as well as 8 500 industrial and marine engines to our customers. Net sales totalled nearly SEK 120 billion, of which about 20 percent were services-related. Founded in 1891, Scania now operates in more than 100 countries and employs some 49 000 people. Research and development are concentrated in Sweden, with branches in Brazil and India. Production takes place in Europe, Latin America and Asia, with regional production centres in Africa, Asia and Eurasia. Scania is part of Traton Group. For more information visit www.scania.com.
Scania is now undergoing a transformation from being a supplier of trucks, buses and engines to a supplier of complete and sustainable transport solutions.
Scania is one of the leading European manufacturers of heavy‑duty vehicles (HDV), with global sales of 82’470 trucks, 8’310 buses and 8’520 engines in 2017. When it comes to energy consumption and global warming, we actively contribute to the necessary reduction of fuel consumption (FC) and greenhouse gas emissions (GHG).
The assessment of future saving potentials, where only concepts or prototypes of the components exist, is done by simulation.
Background:
To determine the consumption of liquid or gaseous fuels, or of electrical energy, the longitudinal motion of the HDV on typical driving cycles and the resulting courses of speed and torque at the engine are simulated. As final step the consumption is interpolated from the performance map of the engine.
For this task a Software-In-the-Loop (SIL) simulation tool is used at Scania (“VTAB” – Virtual Truck and Bus), which simulates the submodels of the mechanical vehicle components together with the real control units. The submodel of the driver in the SIL tool needs to be reworked, to be able to follow start/stop cycles.
Target:
The outcome shall be an English thesis on SIL simulation and the implemented driver model, which can be published by the University. It shall also serve as technical report for the Traton Group, thus the companies Scania, MAN and Volkswagen Caminhões.
Assignment:
– Review existing approaches for driver models for vehicle simulation.
– Select a model principle and implement it in the SIL-tool.
– Assist in the measurement of an HDV on the chassis dynamometer.
– Validate the complete HDV model versus the chassis dyno measurement.
– Contribute to the usability of VTAB.
