Calibration Drivability (Power Train- Gasoline & Diesel)

About the Role 

Drivability Calibration Engineer is responsible for developing, tuning, and validating engine and vehicle control strategies to ensure smooth, responsive, and comfortable vehicle performance across all operating conditions (start, idle, transient, part-load, and full-load). 

Key Responsibilities 

1. Drivability Calibration Development  

Develop and optimize drivability calibration for:         

• Gasoline engines (MPFI, TGDI) 

• Diesel engines (CRDi systems) 

• Calibrate: 

• Tip-in / Tip-out response 

        • Torque structure and request coordination 

       • Transient fuel, rail pressure, and boost control 

        • Injection strategies (Diesel: pilot, main, post injections) 

        • Idle control, cold start, and warm-up behavior 

       • Tune pedal maps for different drive modes (Eco/Normal/Sport) 

2. Torque & System Coordination     

• Ensure robust torque arbitration between:         

• EMS and TCU (MT/AMT/AT/DCT) 

• Optimize:         

• Shift quality (torque reduction, ramp-in/out) 

        • Clutch engagement behavior 

• Coordinate with:         

• Air path (EGR, VGT, throttle) 

        • Aftertreatment systems (DOC, DPF, SCR impact on drivability) 

3. Validation & Testing     

• Perform subjective and objective drivability evaluations 

• Define and track KPIs:         

• Surge / Bucking index 

        • Hesitation / turbo lag 

        • Tip-in delay & torque hole 

        • Low-speed behavior (creep, crawl) 

      • Diesel-specific NVH (combustion noise, torque oscillations) 

• Plan and execute:         

• City / highway / hill / hot & cold condition tests 

• Use tools:         

• ETAS INCA / CANape / AVL Drive 

        • Data acquisition systems (V-Box, iCDM/vCDM) 

4. Issue Analysis & Debugging     

• Identify and resolve P0/P1 drivability issues 

   • Perform root cause analysis using: 

        • Measurement data 

        • System interaction understanding 

• Conduct:         

• On-road calibration refinement 

•  Rapid issue resolution during test trips 

5. Integration & Cross-functional Coordination    

 • Work with:         

• Combustion & Base Calibration Teams 

      • Transmission & Hybrid Control Teams 

       • OBD and Emissions Teams 

• Ensure drivability trade-off alignment with:         

• Emissions (BS6/Euro norms) 

       • Fuel efficiency targets 

        • NVH requirements 

What We’re Looking For 

• B.E, M.Tech (Mechanical, Automobile, Mechatronics). 

• 4 to 8 years of relevant work experience. 

• Experienced in technically leading / working on calibration development projects 

• Excellent knowledge of powertrain systems and sub-systems 

• Good knowledge of developing engine management systems and testing techniques 

• Ability to use model-based calibration tools e.g. Inca, Uniplot, Cameo, ASCMO, AVL Puma, etc. 

• Experienced user of analytical software tools to handle large volumes of data. 

• Ability to understand, interpret and evaluate numerical data 

• Knowledge of Modelling and Simulation techniques 

• Knowledge of coding/programming languages 

• Experience with Hardware-in-the-Loop (HIL) systems 

• Sound understanding of engine combustion processes and emissions formulation 

• Knowledge and experience INCA and ETAS tools. 

• Skilled in statistical testing techniques i.e. Design of Experiments (DoE) 

• Complete work in a safe, timely and professional manner with the minimum of supervision Flexibility to undertake additional task to meet business requirements 

• Highly motivated, keen to learn and share knowledge. High attention to detail 

• Excellent communication skills. 

• Flexibility to travel as and when required. 

Nice to Have 

• Advanced Driver Training Certification – Focus on high-performance vehicle handling, safety, and extreme driving conditions
