Title: Deepa Kesavan: Hybrid Vehicle Powertrain Innovations

Introduction

Deepa Kesavan is an inventor based in Bengaluru, India, whose patent work focuses on hybrid vehicle powertrains and operating-mode control. She is associated with GM Global Technology Operations, Inc. The supplied information lists 3 patents in her portfolio.

Latest Patents

One of Kesavan’s listed inventions, “Methods and Systems for Controlling Shifting Between Operating Modes in Hybrid Vehicles,” describes a method for managing transitions among a hybrid vehicle’s operating modes. The system compares throttle-position values and uses that comparison to determine whether to allow a shift between modes.

Another listed invention, “Single Planetary Hybrid Powertrain with at Least Three Electrically-Variable Operating Modes,” presents a hybrid powertrain built around a single planetary gear set. It combines an engine, two motor-generators, and five torque-transmitting mechanisms, including one brake, to support multiple electric-only, engine-only, and electrically variable operating modes. One embodiment includes an electric torque-converter mode that may serve as a default if a motor-generator fails.

Career Highlights

Kesavan’s listed patent work addresses both control strategies and mechanical powertrain configurations. Together, these inventions illustrate approaches to managing hybrid-vehicle operation and providing flexibility across different driving modes.
