Two of the major focuses of the EcoCAR Challenge have been Model-Based Design and Hardware-in-the-Loop (HIL) simulation. These techniques allow teams to test everything from failures to fuel economy using a virtual vehicle model. They also help to ensure that a robust, reliable and safe control system makes its way into the car.
Throughout the past semester, several members of the University of Victoria EcoCAR Controls Team worked diligently to improve their HIL system, taking advantage of EcoCAR sponsor dSPACE’s advanced Automotive Simulation Models. The team’s upgraded model accurately represents the real vehicle from the ignition and body roll, right down to the frictional forces between the tires and the road. This work has already paid dividends, allowing the team to accurately test their real-time optimization strategy before making any updates to the vehicle. The new model and preliminary on-road testing also confirmed that UVic’s EcoCAR will be capable of 0-100 km/h (0-60 mph) in about 7.5 seconds, as predicted back in Year One!
Check out the video below to see the UVic team’s model running a 0-100 km/h test on dSPACE MotionDesk Software. Don’t let the default car body in the video fool you, ‘under the hood’ is UVic’s model and just like the real car, it is fast
