Detailed Design of Future Sport 1 by Colorado State University for EcoCAR 3 Competition 2019-01-0360
EcoCAR 3 is a four year (2014-2018) competition that is a part of U.S. Department of Energy’s Advanced Vehicle Technology Competition series. As a participant of this competition, Colorado State University’s Vehicle Innovation Team (CSU VIT) redesigned a 2016 Chevy Camaro into a Plug-in Hybrid Electric Vehicle (PHEV) (and titled it as Future Sport 1 (FS1)) with a goal to decrease the environmental impact and increase the fuel economy of the Camaro, while maintaining its performance, safety and consumer appeal. CSU VIT followed an extensive Vehicle Design Process (VDP) to develop the hybrid electric powertrain (including custom mounts and motor housing), control systems, wiring and auxiliary systems. Additionally, the team installed several sensors all over the vehicle to collect data from different components, which is used to analyze the transient and steady state responses of different sub-systems. Moreover, the comprehensive test plans and test procedures developed by the team facilitated the rigorous testing of FS1 at various levels in software, hardware and on-road. They were also helpful in effectively validating the vehicle’s performance and energy consumption as measured by the Vehicle Technical Specifications (VTS). Furthermore, the team focused on the areas of mass reduction that resulted in increased acceleration, efficient powertrain operation that resulted in minimizing overall energy consumption and emissions, and optimal use of engine and motor that resulted in increased all electric range. While there is an incomplete evidence showing that targets have been met in these areas, this study definitively shows improvement from year to year of the competition and specifically during year 4 when the vehicle went through extensive dyno and on-road testing. Our study reveals that the team’s effort helped in improving the drivability, minimizing energy consumption while increasing the overall range, and minimizing the greenhouse gas emissions.
