Abstract Details

2011, Master of Science, Ohio State University, Electrical and Computer Engineering.
The OSU EcoCAR Team is comprised of a diverse group of students ranging from underclassmen to graduate and engineering to business. This diverse team provides both the ability to take on aggressive designs and meet ambitious goals, but also presents a unique set of management and leadership responsibilities. The team management and growth was critical to being successful in meeting timelines and goals amongst diverse experience and levels of involvement. First, this thesis will include elements and details on how this team management and leadership was structured and changed to produce results. Next, the EcoCAR competition vehicle was designed to maximize efficiency and performance while minimizing emissions and petroleum usage. The Ohio State team designed a unique extended-range electric vehicle (E-REV), which uses two electric machines and a battery to power the vehicle for 40-45 miles until an E85 engine turns on and provides the power. The OSU vehicle is unique in its capability to use the front powertrain as an electric drive, auxiliary power unit (APU), or hybrid drive. The design will be explained in this thesis with a specific focus on the benefits of the design and the unique transmission system designed to provide vehicle function. The vehicle design presents a wide variety of controls options and challenges when managing energy, drivability, and performance. This thesis will also dive deeply into controls algorithms and decisions for the vehicle control algorithm design, calibration, and improvements. Topics such as controls hardware and software structure will be explained along with a variety of test results from simulation and vehicle testing. The results show a very comprehensive control system and vehicle design capable of a wide variety of operating conditions and speeds. In all cases, the design provides robust and reliable operation with high efficiency and performance.
