About: 

Functional safety is a core requirement in the development of advanced control functions in automotive systems. The automobile industry has adopted a functional safety standard (ISO 26262), which defines the functional safety requirements and life-cycle management for the safety-related components of automobiles in different phases of the development process.  One aspect of functional safety is the design of diagnostic algorithms that can be integrated within controller design functions at the design stage, to achieve fault-tolerant control system implementation.  The increasing degree of automation in vehicles will make this subject increasingly important in the future.

 

This seminar outlines a model-based methodology for diagnostic design that is consistent with ISO 26262 functional safety standard and can be generally applied to any automotive system. The talk outlines the key elements of the approach and presents an example – the application of the method to the implementation of torque security features in an electric vehicle drivetrain.

Biography: 

Giorgio Rizzoni, the Ford Motor Company Chair in ElectroMechanical Systems, is a Professor of Mechanical and Aerospace Engineering and of Electrical and Computer Engineering at The Ohio State University (OSU). He received his B.S. (ECE) in 1980, his M.S. (ECE) in 1982, his Ph.D. (ECE) in 1986, all from the University of Michigan. Since 1999 he has been the director of the Ohio State University Center for Automotive Research (CAR), an interdisciplinary university research center in the OSU College of Engineering.  His research activities are related to modeling, control and diagnosis of advanced vehicles, energy efficiency, alternative fuels, the interaction between vehicles and the electric power grid, vehicle safety and intelligence, and policy and economic analysis of alternative fuels and vehicle fuel economy. He has contributed to the development of graduate curricula in these areas, and has served as the director of three U.S. Department of Energy Graduate Automotive Technology Education Centers of Excellence: Hybrid Drivetrains and Control Systems (1998-2004), Advanced Propulsion Systems (2005-2011, and Energy Efficient Vehicles for Sustainable Mobility (2011-2016). Since January 2011 he has served as the OSU Site Director for the U.S. Department of Energy China-USA Clean Energy Research Center - Clean Vehicles. Prof. Rizzoni is a Fellow of SAE (2005), a Fellow of IEEE (2004), a recipient of the 1991 National Science Foundation Presidential Young Investigator Award, and of several other technical and teaching awards.
