Deputy Manager - Vehicle Attributes

Responsibilities & Key Deliverables

Roles & Responsibilities

• Execute vehicle-level NVH & VD validation, subjective and Objective to ensure achievement of defined noise, vibration, and harshness and steering, brakes, handling and ride targets across all operating conditions.


• Should be able to conduct BSR Testing and score generation. Acoustic and vibration data along with subjective sound quality assessments to support vehicle refinement.


• Identify NVH & VD performance gaps early and provide data-driven inputs for design improvements (BIW, powertrain mounts, trims, sealing, etc.).


• Benchmarking of Vehicle Attributes viz. Power Train Noise, Road Noise, Wind Noise and Idle Boom Noise and Ride, Handling, Braking, Steering and Stability.


• Need to establish and maintain good inter-personal and inter-departmental relations and with the track management authorities.

  • Capture key signals: cabin noise (dB), acceleration, rpm, torque, etc.
  
  
  • FFT, Spectrogram, Waterfall analysis
  
  
  • Order tracking and run-up/coast-down analysis
  
  
  • Transfer Path Analysis (TPA) basics
  
  
  • VD performance gap identification reports with supporting evidence
  
  
  • Benchmark comparison reports with competitor vehicles
