Abstract

A method for estimating the current flowing through a winding of an electric motor of the type having one winding controllable by a switching device, including the following steps: measuring a voltage at the input of the winding, correcting the measured voltage to produce a corrected voltage determining a resistance of the switching device, estimating the current flowing through the winding by dividing the difference between a control voltage used to control the switching device and the corrected voltage by the resistance. The use of such an estimating method for providing a diagnosis for a current sensor, and an estimating method for controlling an electric motor in fail-soft mode are also disclosed.
