CAR faculty and researchers presented with best paper award at 2017 IEEE International Transportation Electrification Conference
Giorgio Rizzoni, director, Center for Automotive Research (CAR), Dr. Jeff Chrstos, advisor to the Formula Buckeyes Motorsports Student Team and Dr. Matilde D’Arpino, CAR research associate along with Martin Villing from the University of Stuttgart who spent 6 months at CAR as a visiting scholar, received the best paper award for their paper titled “Dynamic modeling for electric vehicle land speed record performance prediction” at the 2017 IEEE International Transportation Electrification Conference in Harbin, China.
The paper describes the computational tools developed by the Venturi Buckeye Bullet 3 team used to study the performance of their land speed record vehicle. The co-simulation approach uses two commercial software packages, MATLAB™ and CarSim™, to simulate the vehicle dynamic stability (both aerodynamics and chassis stability) when coupled with the 1.5MW all-wheel drive electric powertrain. The tools perform computations that involve the dynamic performance of the vehicle, the power electronics and electric machines, the battery systems and the thermal performance of each subsystem. The co-simulation tool is capable of interacting with software that emulates all of the control systems on board the vehicle, thus providing the ability to simulate real world conditions prior to testing the control algorithms on the Salt Flats.
“The work that has been done (and is currently being done) on the Bullet is simply exceptional, and it is great to see that we are being recognized internationally,” said Rizzoni. “When you take a step back and look at the paper from afar, it is really impressive.”
As a result of this study, an accurate simulation tool, named VBB3Sim, has been developed to evaluate vehicle stability, shift strategy and new hardware installation impact on performance.
