Master of Sciences (MS), Mechanical Engineering, GPA: 4.00 / 4.00 Related Coursework: Hybrid Electric Vehicles and Automotive Controls Aug 2016-Present

Thapar University, Patiala, India July 2010- May 2014 Bachelor of Engineering (BE), Mechanical Engineering, GPA: 8.71 / 10.00 ENGINEERING PROJECT EXPERIENCE

I. Title: Development and Validation of control system for configurable hybrid electric learning module (CHELM) using model based embedded control design approach and state flow. March 2017-May 2017

• Designed an HEV controller including a high-level Moto Tron controller, an engine ECU and motor controller in Simulink/ Matlab which determined the torque blending between IC engine and motor based on control strategy.

• Developed six subsystems in control module which takes the input parameters from automotive sensors and process them to actuate the stepper motor subsystem in actuator module for further engine throttle actuation.

• Modified the control logic by incorporating factors like battery SOC, brake pedal position to improve the torque blending strategy, braking efficiency and enhance the performance of hybrid electric vehicle.

• Learning: Well versed with development of embedded control systems for automotive applications like ECU, TCU and vehicle control unit using Moto Tron Rapid Prototyping systems. II. Modelled and validated the closed loop feedback electronic throttle control mechanism in Moto Tron using the Controller Area Network (CAN) Communication. Jan 2017- March 2017

• The discrete controller based on PID was designed to optimize the error signal between accelerator pedal position and throttle position.

• The sensor and stepper motor actuation system was built in ECU 2 while the PID discrete controller was built in ECU 1. The CAN King was used to monitor message transmission between two ECUs. III. Title: Optimized the Configuration of Hybrid Electric Vehicle by using commercial grade vehicle simulation software ‘AVL Cruise’ and extensively testing the vehicle on Chassis Dynamometer to validate the results

• Simulated the CHEV model in different driving scenarios using AVL Cruise within the constraints of available design parameters of body, axle ratios, tires, powertrain, electrical system etc to obtain the optimal configuration.

• Tested the vehicle on chassis dynamometer to determine the impact of design parameters on the vehicle performance within the given constraints and targets of mass and cost to experimentally determine the best architecture.

• Worked with ETAS INCA as data acquisition tool while analysing data on chassis dynamometer. IV. Title: Fuel Injection Control for 500cc single cylinder 4 stroke gasoline cycle engine using Moto Tron Rapid Prototyping System. Jan 2017- Feb 2017

• Modelled the fuel injection control system in Simulink using Moto Hawk including the crank rpm, exhaust gas temperature as inputs and refined the relation between these inputs and injection parameters like injection duration.

• Designed temperature compensation and protection model to improve the fuel injection control by regulating exhaust gas temperature between an optimal range.

• Learning: Well versed with Hardware in Loop testing (HIL) and state of art gasoline engines. PROFESSIONAL WORK EXPERIENCE

Development Engineer, Research and Development (R&D), Hero Moto Corp Ltd. July2014-June2016

• Developed proficiency in development of Casting and Forging powertrain components such as Gears, Pistons, Piston rings Crankshaft, sprockets etc. for newly developed two-wheeler motorcycles.

• Worked as Development Project leader for powertrain development of two models ‘Hero Duet and ‘Hero Achiever’.

• Headed the team for prototype vehicle assembly activities and development of evaporative emission control parts like carbon canister etc. for new in-house projects that conformed Bharat Stage IV emission standards (Indian Standards).

• Manufacturing Feasibility study on 2D and 3D Cad data of powertrain components using product lifestyle management tools like TeamViewer. Developed proficiency in GD&T and APQP Documentation SKILLS

• MotoHawk/MotoTune • ETAS INCA • C / C++ • Matlab/ Simulink

• DS Solidworks • CANCommunication • Ansys • MS Excel

• Dassault Catia V5 • AVL Cruze • NI Labview • SAS
