Electric drive unit simulation

A computer-implemented method of simulating operation of an electric drive unit to predict one or more performance parameters of the electric drive unit, the electric drive unit comprising at least an electric motor, the method comprising:

• obtaining parameters defining physical properties of the electric motor;
• obtaining parameters defining drive currents for driving the electric motor;
• processing the obtained parameters using a machine learning module trained a priori to predict a spatially varying electromagnetic and/or mechanical and/or thermal profile within the electric motor during operation, and providing as output a predicted profile for the electric motor and a parameter indicating an uncertainty associated with the predicted profile,
• determining that the uncertainty associated with the predicted profile is greater than a threshold;
• generating, in response to determining that the uncertainty associated with the predicted profile is greater than the threshold, a new predicted profile comprising a training electromagnetic and/or mechanical and/or thermal profile within the electric motor during operation generated by solving a system of predefined equations for the obtained parameters;
• performing additional training of the machine learning module using the new predicted profile and the obtained parameters;
• and
• using the new predicted profile to compute the one or more performance parameters of the electric drive unit.
