Case study of a Multidisciplinary Engineering Capstone Design Project: Electric Drive Control SystemThis paper presents the design and development of an electric drive control system for a multi-motor vehicle with independently driven wheels that can be used as a platform to test an electriccar’s differential drive function. This project was accomplished as a Capstone Senior Designproject consisting of two students from the School of Mechanical Engineering and three studentsfrom the School of Electrical and Computer Engineering. The design team was advised by twofaculty members: one Mechanical Engineering and one Electrical and Computer Engineering.The motivation behind this project was to simplify the mechanical layout of future electric carsby connecting the motors directly to the wheels. This design would reduce the number ofdrivetrain components, thus improving the overall reliability and efficiency. This paper providesdetails about the design and development of the intelligent electric drive system, as well astesting and validation.The paper focuses on the systematic design process used by the multidisciplinary team in orderto accomplish their project. The design project was adequately partitioned between the studentsfrom the two majors to ensure that the entire team could contribute effectively while being ableto leverage from the expertise of all team members. Based on the team’s experience and facultyinteraction, future guidance on how a sustainable model for enabling multidisciplinary capstonedesign projects is also suggested.
