Realtime Simulation of Detailed Vehicle and Powertrain Dynamics

Elmqvist, Hilding and Mattsson, Sven Erik and Olsson, Hans and Andreasson, Johan and Otter, Martin and Schweiger, Christian and Brück, Dag (2004) Realtime Simulation of Detailed Vehicle and Powertrain Dynamics. In: Electronics Simulation and Optimization. SAE 2004 World Congress, 2004-03-08 - 2004-03-11, Detroit.



This paper describes typical modeling and real-time simulation issues that occur in automotive applications. Real-time simulations of detailed Modelica benchmark models for chassis and powertrain are presented. They demonstrate the powerful real-time capabilities of Dymola and the Modelica modeling language. One of the benchmark models for vehicle dynamics is a detailed model with 72 degrees-of-freedom with bushings in both the front and rear wheel suspensions. It was simulated in real-time with a sample rate of 1 kHz on the RT-LAB environment from OPAL-RT using a Pentium 4, 3066 MHz processor. This is made possible by Dymola's unique and elaborate symbolic processing of the model equations.
