Latest Patents
Powertrain with Compound-Split Hybrid Transmission Having a Reduced Ravigneaux Gear Set. This invention describes a powertrain built around a planetary gearing arrangement with two sun gears, two ring gears, a single carrier, and an interconnecting member linking either the sun gears or the ring gears. Two electric machines drive selected gear members, while a selectively engageable brake can hold the input stationary. The arrangement is designed to support compound-split hybrid operation.
Hybrid Transmission with Single Planetary Gear Set and Multiple Operating Modes. This patent describes a hybrid transmission with one planetary gear set connected between the input and output. Two electric machines and four selectively engageable torque-transmitting mechanisms work together to establish series, input-split, electric-only, and fixed-gear operating modes.
Career Highlights
Ravichandran’s listed inventions focus on hybrid transmission architecture, planetary gear arrangements, and the coordination of electric machines with mechanical components. These designs address how a powertrain can provide different operating modes through selective engagement of gears, brakes, and torque-transmitting mechanisms.
Collaborations
His listed coworkers include Kumpatla Vvp Naidu and Ravikanth Gv. His work is associated with GM Global Technology Operations, Inc.
Conclusion
Sriram Ravichandran’s patent portfolio reflects a focus on hybrid powertrain engineering, particularly transmission designs that combine planetary gearing and electric-machine control to enable multiple operating modes.
