PXI HIL Systems


Purpose

HIL system for automotive ECU validation

Features

The system is based on the NI Veristand software platform. The hardware platform is NI PXI chassis and real-time controller, with the addition of other I/O modules from NI, third party manufacturers and Alma Automotive custom devices. The following is a baseline list of features that can be modified based on specific user needs:

  • Real time controller with last generation processing power (up to quad core CPUs)
  • Easy system definition with Veristand System Explorer interface
    • Base system configuration (step-time, cpu allocation)
    • HW channels definition (analog, digital, CAN)
    • Model DLL import from Labview or Simulink/Stateflow
    • User and calculated channels definition
    • Channel mappings
    • Custom devices setup
  • Flexible GUI for easy run-time customization of the workspace
  • FPGA based engine simulation module with
    • Dual channel VRS/Hall engine position sensor simulation capable of 120Vpp
    • Angle based waveform generation module
    • Quad channel wheel simulation
    • 12 channels high-voltage angle based inputs
    • 16 channels high-voltage general purpose digital inputs (on/off, frequency, PWM)
    • 8 channels high-voltage analog inputs
  • FPGA based fault insertion units 
    • 32 channels power FIU, with 2 general purpose busses + open circuit, 20A capable
    • 64 channels sensors FIU, with 4 general purpose busses + open circuit, 2A capable
    • Make-before-break switch operation
    • User selectable fault current limiting with feedback signals
  • High resolution resistor simulation
  • Rugged desktop rack enclosure
