Built Simulink models of engine control software features and developed an Arduino based test-bench scale CAN system.• Developed Simulink models for implementing engine control software features based on C source code.• Designed Stateflow charts for realizing the logical constructs which characterize the software feature.• Gained thorough understanding of Simulink, code-logic, and platforms for development.• Trained other interns on Controller Area Network (CAN), SAE J1939, and diagnostics.• Coded Data Link for CAN bus test bench using C, PCAN-USB software interface, and Simulink.• Studied microprocessors, datasheets and developed a good understanding of GPIO and general C programming.

Transmission Automatics Application - Drivetrain EngineeringLed a team of four engineers to handle development, integration, release, delivery, and field issue resolution of Automated Manual Transmissions (AMT) and fully Automatic Transmission (AT) systems for trucks and buses.• Reduced failure rates by 30% by developing AMT system with a new diaphragm clutch for commercial vehicles.• Saved 30,000 USD warranty costs approx. annually and improved product reliability by resolving gearbox synchronizer failures and gear shifting failures in a bus with AMT and ZF 6S transmission.• Improved end-customer experience rating from 6.5/10 to 9/10 by resolving drivability issues in an airport transit bus. • Enhanced shift comfort rating from 7/10 to 9/10 by tuning shift strategy in AMT system in a 12-ton haulage truck.• Achieved 5% reduction in fuel consumption in a 12-ton haulage truck with AMT based on targeted duty cycle analysis and in metro-buses by introducing a new functionality in Allison AT system.• Identified 1050 USD per vehicle worth cost reduction ideas and developed parts for AT systems.

Manual Transmissions and Change Speed Operation Systems Application - Drivetrain EngineeringExecuted special projects transmission system application and released drawings for system reliability improvement.• Configured and verified a new, 8% more fuel efficient drivetrain for 31-ton truck based on simulations in AVL-Cruise.• Reduced failure rates by 20% and saved 50,000 USD warranty costs annually by improving reliability in cable gear-shift system design in 12-ton haulage truck.• Improved reliability and reduced part variants by developing gearbox input shaft spline for a new diaphragm clutch.

Vehicle Evaluation & Testing Calibrated, tested and validated vehicle systems, engine systems, transmission systems, OBD systems, and fuel efficiency systems of various truck and bus models.• Enhanced fuel efficiency by 6% and verified the same in an AMT equipped city transit bus.• Executed OBD calibration, engine systems calibration for speed governing, vehicle speed limitation, and drivability.• Reduced testing lead times by 20% using data analysis tools to condense vehicle road duty cycles. • Led a team of 3 engineers to deliver prototype builds and provided operations support for the proto runs at the newly established vehicle assembly shop.

• Reduced the recurrence of motor-tripping due to kickback of hot-rolled steel slabs by 90% by designing a chain drive to connect the adjacent motors for better load sharing.
