The benefit 

This report provides results essential for NVH Managers and Vehicle Systems Leaders in EV OEM’s and Tier 1 suppliers to enable vehicle level comparisons and cascaded system level target setting from the latest premium EV benchmark. Ricardo is an industry leading authority on platform benchmarking with NVH expertise spanning almost 50 years of engineering excellence within the automotive sector. 

The report insights 

The Ricardo NVH engineers focussed the benchmarking of the I-Pace on the vehicle and system levels covering the following:

Subjective NVH assessment

  • EV powertrain, road noise and other significant NVH attributes

NVH design review

  • Assessment of key NVH points of interest

Proving ground data

  • Transient, steady state and stationary operating conditions
  • Interior noise and vibration
  • Evaluation of Jaguar Enhanced Sound Design System
  • Dominant order identification including Tone-in-Band analysis
  • Front and rear Electric Drive Unit (EDU) radiated noise
  • Structural isolation across front and rear EDU mounts
  • Road noise including hub vibration on road noise generating surfaces

NVH Facility Data

  • Sound Transmission Loss (STL) from front and rear EDU
  • Vehicle Acoustic Transparency
  • Noise and Vibration Transfer Functions
  • Attachment Stiffness
  • Equivalent Body Hole Size

NVH data (approx. 30Gb)

In addition to the report, Ricardo will supply a copy of the raw benchmarking data in ATFX format.  The data has been measured with a high sampling frequency (approximately 30Gb in size) and includes:

Proving Ground (Time) Data:

Interior noise and vibration, vibration measurements across EDU mounts and vibration measurements on wheel hubs:

  • Acceleration:
    • Full load (WOT) in Standard & Dynamic chassis modes
    • 0.05G and 0.1G part load
  • Run Down:
    • High and low regenerative braking
  • Steady State Driving:
    • 30, 50 and 70kph on coarse road
    • 30, 50, 70, 110 and 130kph on smooth road

Interior noise and vibration, noise measured at 6 points around each EDU

  • Acceleration:
    • Full load (WOT) in Standard & Dynamic chassis modes
    • 0.05G and 0.1G part load
    • 25%, 50% and 75% accelerator pedal position
  • Run Down:
    • High and low regenerative braking
  • Steady State Driving:
    • 30, 50 and 70kph on coarse road
    • 30, 50, 70, 110 and 130kph on smooth road
  • Jaguar Enhanced Sound Design System:
    • Full load – disconnected, nominal (mid) and max setting
    • Run Down – disconnected, nominal (mid) and max setting
    • 0.05G and 0.1G part load – nominal (mid) setting

Stationary (Time) Data:

  • Interior noise and vibration:
    • No and high load (e.g. A/C off and AC on)
    • HVAC min, mid and max settings

Additional Points of Interest:

  • Interior noise and vibration:
    • Door handle return noise
    • Brake servo noise
    • Door lock / un-lock noise
    • Warning noise in reverse

NVH Facility Data

    • Front (4) and rear (4) EDU mounts to interior noise at:
      • Front LHS and rear RHS Seats (Binaural Head)
      • Front RHS and rear LHS Seats (Microphones)
  • Vibration Transfer Functions (Spectral Data):
    • Front (4) and rear (4) EDU mounts to interior vibration at:
      • Driver seat rail
      • Rear seat base
  • Sound Transmission Loss Data (Time Data):
    • High frequency volume velocity source to:
      • 6 microphone locations around front and rear EDU
      • 4 locations external to vehicle (front/Rear/LHS/RHS at 1m distance @ 1.5m high)
    • Low frequency volume velocity source to:
      • 6 microphone locations around front and rear EDU
Relevant to:
  • Automotive
Topics:
  • Powertrain
  • Vehicle electrification
  • Future mobility
