Abstract:
The invention relates to a method for switching off a multi-phase electric machine ( 110 ) in a motor vehicle, the multi-phase electric machine ( 110 ) comprising a rotor having a rotor winding ( 101 ) and a stator having a multi-phase stator winding ( 110 a ), wherein in a block mode ( 210 ) of the electric machine ( 110 ) a parameter influencing a pole wheel voltage vector (U p ) of a pole wheel voltage is adjusted such that the pole wheel voltage reaches a first threshold value (S 1 ), wherein the block mode ( 210 ) is deactivated when the first threshold value (S 1 ) is reached and a PWM mode ( 220 ) for applying a phase voltage with a phase voltage vector (U s ) is activated, wherein the phase voltage vector (U s ) and the pole wheel voltage vector (U p ) are varied in PWM mode ( 220 ) until the parameter influencing the pole wheel voltage reaches a further threshold value (S 2 ), wherein the phase voltage is switched off when the further threshold value (S 2 ) is reached. Furthermore, the invention relates to a computing unit ( 112 ) configured to carry out the method.
