MEA RDS Four-Quadrant Operation

MEA Powertrain testing systems are fully integrated Modular System with Integrated HiL using INTECH orangeHiL.

MEA can supply “Electric Powertrain Dynamometer” that will include the capabilities for testing:

  • Full Car
  • Reduction gear
  • Electric Motor Under Test
  • 2WD FF Driveline
  • 2WD FR Driveline
  • 2WD Powertrain
  • 4WD Driveline
  • 4WD Powertrain

HiL system for testing individual ECUs and integrated networks, including real-time simulation and test automation.

Real-Time Simulation includes:

  • Real-time simulation of vehicle/driver
  • To accelerate / to brake / to change vehicle states

 

System Capabilities:

Option 1: Drive Cycle

  • Predefined drive cycles:
  • Longitudinal drive cycle simulation/modeling of longitudinal dynamic.

Option 2: Virtual Test Driving

  • Real-time simulation environment with full real-time capabilities.
  • Integrated model environment for the construction of conventional, hybrid, and battery electric power train systems, including their operation strategy and coupling with the hydraulic braking system in CarMaker(*).
  • Driver model in CarMaker for driving cycles and driving 3D tracks. (*) CarMaker: Real-time simulation of passenger cars and light-duty vehicles.

MEA Powertrain testing capabilities also include
