4WD Powertrain Test System Facility at Millbrook for Emissions Testing and Electric and Hybrid Powertrain Integration

4WD Powertrain Test System

Millbrook's 4WD Powertrain Test System is ideally suited to advanced development of hybrid and electric powertrains, transmissions and advanced vehicle control strategies.

It has four hub-mounted high dymanic dynamometers and a 350kW battery
simulator. It can also be used to test laid-out powertrains (PIL) or full
vehicles (VIL).

Applications

  • Vehicle-in-the-Loop (VIL) simulation and test capability
  • Powertrain-in-the-Loop (PIL) simulation and test capability
  • IC or hybrid emissions development, including simulation of real world and regulatory cycles
  • Electric vehicle and battery management system development
  • Powertrain testing with a virtual battery using the battery simulator
  • Powertrain control strategy development
  • Development of ABS and traction control systems using fully integrated tyre slip models
  • Mule use of components to simulate future vehicles
  • Condensed testing on a rig as opposed to track or road-based testing
  • Highly repeatable measurement of fuel economy, emissions and energy consumption
  • Fuel and lubricant trials in a highly repeatable environment
  • EDU and e-axle functional development and durability
