Research: Look-ahead control of autonomous vehicles

“A passion for automobiles together with an awareness of our world’s environmental and energy challenges inspired me to pursue a career in engineering. I graduated from Purdue University with a Bachelor of Science in Mechanical Engineering in 2014. During my time as an undergraduate student, I completed four cooperative education terms at General Motors in southeast Michigan in the areas of active safety controls, gasoline engine controls, and turbocharging. I also worked with Dr. Gregory Shaver at Purdue’s Herrick Labs on a project related to internal combustion engine modeling. After graduation, I continued at GM in controls and calibration of a new high tech family of gasoline engines. This work acquainted me with current controls engineering problems and deepened my interest in the specialty. In order to study such problems in further detail, I traveled to Clemson University and joined Dr. Vahidi’s research team in the fall of 2016. My current research is in anticipative control of autonomous on-road vehicles. Outside of academics, I enjoy modifying my project car, target shooting, and playing guitar.”

Angshuman Goswami (M.Sc., since F15) — E-mail: agoswam@clemson.edu

Research: Off-road autonomous driving

My interest in automobiles was ignited in high school. Besides working of the engine, what intrigued me was the fact that such a large powerhouse was controlled with the help of a tiny computer (the ECU). My interest took real shape as an undergraduate student when I got the opportunity to join National Institute of Technology, Bhopal, India and work under Dr. Ameenur Rehman Siddiqui on analysis of fuel spray pattern. I joined VE Commercial Vehicles Ltd. (part of the VOLVO group) and worked for 5 years in engine controls and calibration. I had lead the development of a 4 cylinder light duty Selective Catalytic Reduction (SCR) Euro IV OBDII engine and was the part of the team which developed the first Euro IV commercial vehicle engine in India with Exhaust Gas Recirculation (EGR) and only Diesel Oxidation Catalyst (DOC). With a long term vision of making feasible and cost effective solution for the automotive market of the developing world, I joined Dr. Vahidi’s research group in Clemson University in 2015. Currently I am working on off-road autonomous driving using connected vehicle technology. I am also working on a robot equipped with Inertial Measurement Unit (IMU), camera and ultrasonic sensors, developing algorithms for point cloud terrain mapping and autonomous driving. In my leisure time, I love reading on global politics, history, astronomy, latest tech trends, watching football and cricket.

seneca

Seneca Schepmann (M.S., since F08) — E-mail: sschepm@clemson.edu

Graduated: August 2010

Thesis: “Ultracapacitor Heavy Hybrid Vehicle: Model Predictive Control Using Future Information to Improve Fuel Economy”

Now: Controls Engineer at Proterra (Greenville, SC)

After pursuing undergraduate research on the Electric Bicycle project where I investigated the bicycle’s regeneration capabilities and control functions, I continued my graduate studies here under Dr. Vahidi working on modeling and simulation of hybrid vehicle powertrain. This research is concerned with the improvement in the fuel economy of heavy transport vehicles through the use of high power ultracapacitors in a mild hybrid electric vehicle platform. Among all hybridizing energy storage technologies, ultracapacitors pack extraordinary power capability, cycle lifetime, and ruggedness and as such are well suited to reducing the large power transients of a heavy vehicle. The control challenge is to effectively manage the very small energy buffer (a few hundred Watt-hours) the ultracapacitors provide to maximize the potential fuel economy. The optimal control technique of Dynamic Programming is first used on the vehicle model to obtain the ”best possible” fuel economy for the vehicle over the driving cycles. The Model Predictive Control (MPC) method is an optimization-based receding horizon control strategy which has shown potential as a powertrain control strategy in hybrid vehicles. An MPC strategy is developed for the hybrid vehicle based on an exponential decay torque prediction method which can achieve near-optimal fuel consumption even for very short prediction horizon lengths of a few seconds. A critical part of the MPC method which can greatly affect the overall control performance is that of the prediction model. The use of telematic based “future information” to aid in the MPC prediction method is also investigated. Three types of future information currently obtainable from vehicle telematic technologies are speed limits, traffic conditions, and traffic signals, all of which have been incorporated to improve the vehicle fuel economy.

Upon receiving my Master’s degree in August 2010, I took some time off and traveled the world in my personal catamaran(not really). I am currently working for Proterra as a Controls Engineer, where I am contributing to the design and validation of the vehicle control systems, as well as further process improvements as Proterra prepares to ramp up production. More information on Proterra, a leader in breakthrough battery-electric (and hybrid) vehicle technologies in the transit industry, can be found at www.proterra.com
