Design And Development Of A Virtual Driver Model And A Hybrid Supervisory Controller

Design and Development of a Virtual Driver Model and a Hybrid Supervisory Controller

Sponsored by the Department of Energy, General Motors, and Mathworks, the EcoCAR Mobility Challenge challenges 12 universities team across North America to redesign a 2019 Chevy Blazer into a SAE Level 2 Automated Hybrid Electric Vehicle. This work focusses on the development and validation of a vehicle’s hybrid supervisory controller in a virtual test environment. The development of a virtual environment focuses on the design and implementation of modeling a driver that ensures valid driver request by minimizing pedal oscillations and meeting EPA requirements for competition specific drive cycles. The design of the hybrid supervisory controller explains decisions that were made related to the hardware selection, serial architecture, interface between connected and automated vehicle technology and the propulsion controls, and the software development. The hybrid supervisory controller was designed for initial implementation that focuses on testing component interfaces, power moding, and a simplified torque split strategy. The hybrid supervisory controller was broken into various sub algorithms that were designed and validated on a unit level. Overall, both the driver and the controller have been validated in a virtual environment and will continue to be improved during the vehicle implementation phase.
