The University of Victoria Explores Advanced Simulation Capabilities

The University of Victoria (UVic) team is excited about its new advanced dSPACE-founded vehicle dynamics model. UVic has been using dSPACE hardware and software through the first year of EcoCAR 2 for purposes of modeling, simulation and prototype development. To meet the challenge of developing a realistic vehicle propulsion controller design for their all-wheel-drive (AWD) series-parallel plug-in HEV, engineering students from the Canadian university turned to dSPACE’s Vehicle-Dynamics Automotive Simulation Model (ASM) for greater fidelity and simulation capabilities. With this dynamic simulation tool, they are able to create a fully parameterized vehicle model with dynamic capabilities.

dSPACE donated high-fidelity vehicle simulation models to all 15 teams in the EcoCAR 2 competition. These donations were parameterized towards 3 of GM’s engines and interact accordingly with engine/transmission controller module models. Other drivetrain components, such as a multi-speed automatic transmission, electric machines, and A123-parameterized multi-cell batteries are also included in this ASM library to fully simulate the capabilities of EcoCAR 2 teams’ HEV architecture designs. The additional automated driver environment provides the ability to issue both propulsion and steering requests in real-time.

The ability to fully parameterize the vehicle’s suspension, mass distribution, and compliant shafts provide an ideal platform for the team’s traction and stability control systems, as well as front/rear traction torque distributions. Such algorithms will be improved and integrated into the re-designed 2013 Chevrolet Malibu upon its completion this year. In the third “optimization” year of competition the team will be able to analyze the effects of suspension modifications and vehicle handling.
