NovaCarts eEngine: Dynamic real-time simulation of electric motor control units

NovaCarts eEngine allows automotive manufacturers and suppliers to simulate complete electric motors. The HiL simulator's high dynamics allow various control units used in hybrid vehicles to be tested under realistic conditions.

The electric motor models of NovaCarts eEngine are designed as software – unlike other solutions available on the market. This means that test engineers no longer need to spend valuable time converting them to FPGA models.

NovaCarts eEngine is suitable for automated testing of new software versions as well as for special test routines in accordance with the OBD standard. Furthermore, the electric motor simulator can be easily and quickly combined with NovaCarts Battery, allowing automotive manufacturers and suppliers to simulate the entire electrically powered powertrain of electronic or hybrid vehicles with voltage curves under load, and to test the communication between the battery management system and the electric motor.

4 reasons for NovaCarts eEngine

  • Versatile use: Extensive testing of all electric motor control units used in the hybrid/electric drive - component tests are possible with the aid of extensive residual bus and signal simulations or compound tests as well as manual or automated test processes
  • Shorter compilation times thanks to software-based models
  • Fast control unit change due to modular design and connection of test specimens via cable harness
  • User-friendliness: Matlab/Simulink model for physical simulation can be configured and extended as required


  • High-resolution simulation model with step width of a few tens of microseconds thanks to distribution over separate processor cores. The software outsources the highly time-critical portions to fast FPGA hardware.
  • Simulation of position encoder signals (analog, digital and modulated)
  • CAN matrix with error activation, measurement and rest-bus simulation
  • Error simulation of the pilot line, position encoder sensors as well as in accordance with the OBD1 standard
  • Simple access to low-voltage signals via a matrix switch
  • Simulation of phase currents and phase voltage
  • Operation in a star or triangle constellation possible
  • Combined operation with NovaCarts Battery possible
