On-Road and Chassis Dynamometer Evaluation of a Pre-Transmission Parallel PHEV 2019-01-0365
The paper details the testing activities performed during the Year 4 of the EcoCAR 3 competition by the Wayne State University team. The paper presents the objectives of each road and chassis dynamometer test, and the setup accomplished for the different vehicle testing platforms. The results obtained from each test are presented and discussed along with the impact of the results on the refinement of the operational control strategies for the vehicle hybrid modes .
The EcoCAR 3 competition challenges sixteen North American universities to re-engineer a 2016 Chevrolet Camaro to reduce its environmental impact without compromising its performance and consumer acceptability. The team is in the final stages of the fourth year of the competition, which, as the “refinement year”, focuses on the optimization of the control strategies designed within the Hybrid Supervisory Controller unit to achieve a 99% buyoff vehicle which incorporates energy saving features and performance.
Over the course of Year Four, the team used various simulation platforms to test the control algorithms designed for each vehicle operational. While Model-in-the-Loop and Hardware-in-the-Loop environments have been the main focus of Year Two and Year Three, during the fourth competition year a considerable amount of time has been spent on chassis dynamometer and closed-course vehicle testing. The control strategies have been tested over a variety of standard drive cycles to identify the need for refinements and improve the robustness of the algorithms for performance improvement and emissions and energy consumption reduction. In addition, the results obtained have been used to validate the component plant models and to support further development of the operational strategies within the non-vehicle platforms.
