50th Anniversary Seminar Series: Ram Vasudevan on Models of Vehicle Behavior

November 10, 2015 - 11:30am
Sponsor: UMTRI 50th Anniversary Seminar Series

Driver Modeling for Active Safety Systems that Dissuade Overdependence 

Abstract: Decades of vehicular safety systems (e.g. airbags, antilock braking systems, seat belts, etc.) have steadily decreased the number of fatalities due to motor vehicle accidents until recently. Despite the increased number and quality of sensors, improved advanced control architectures, and the deployment of communication networks with infrastructure and between vehicles, the number of fatalities due to motor vehicle accidents in the U.S. has plateaued. Developing active safety systems to address this problem has been challenging, since any such system must be certified to behave correctly during operation without unwittingly encouraging recklessness by giving drivers a false impression about the power of autonomy. 

This talk will describe how probabilistic models of vehicle behavior can be used to address this problem. In the first portion of the talk, Professor Vasudevan will describe a semi-autonomous architecture that constructs a real-time driver-specific model, which informs a controller that is able to safetly correct dangerous driver input to prevent vehicular accidents. In the second portion of the talk, he will describe how this architecture can be extended to unseen circumstances to still prevent accidents with intermittent interventions while dissuading overdependence. 

Bio: Ram Vasudevan is a Research Assistant Professor at the University of Michigan Tranportation Research Institute (UMTRI) and Assistant Professor in Mechanical Engineering at U-M. He received a BS in Electrical Engineering and Computer Sciences and an Honors Degree in Physics in May 2006, a MS degree in Electrical Engineering in May 2009, and a PhD in Electrical Engineering in December 2012 all from the University of California, Berkeley. He completed a postdoc in the Computer Science and Artificial Intelligence Laboratory at the Massachusetts Institute of Technology. His research interests include dynamical systems, optimization, and robotics especially with applications involving human interaction. 

The seminar will begin at 11:30am in the UMTRI McCormick Conference Room. Lunch immediately following. 

Please RSVP for the seminar by Thursday, November 5, 2015.
