A method and strategy for providing real-time estimates of the machine parameters of an induction machine, including rotor resistance, rotor inductance, stator resistance, stator inductance and mutual inductance. The induction machine is a part of a torque delivery driveline. The method comprises expressing stator voltage as a function of machine parameters, stator current, stator excitation frequency and slip frequency. A functional relationship of rotor current, rotor resistance, rotor flux, electrical speed of applied stator voltage and rotor electrical speed is defined. Rotor current and characteristic parameters are calculated, the machine parameters being calculated using the characteristic parameters.
