Abstract
A control method for a vehicle drive assembly includes applying a conduction angle set point value to a variable reluctance machine. The method also includes regulating the conduction angle set point value by comparing a table set point torque from an angle table and a torque estimation value to determine a control measurement of torque delivered by the drive assembly. The control measurement of torque is corrected to an additional conduction angle which is added to a set point angle from the angle table to determine the regulated conduction angle set point value.
