Claim 7:
8. A vehicle comprising:
an arrangement for an electric or hybrid-electric drive, the arrangement being for detecting a direction of rotation of a multi-phase electric motor, the arrangement comprising:
a plurality of single-phase converters, each single-phase converter of the plurality of single-phase converters supplying one phase of the multi-phase electric motor with current;
two sensor units that are configured to determine actual values of phase currents of the multi-phase electric motor and to transmit the actual values of the phase currents to the plurality of single-phase converters; and
a monitoring and control unit in each single-phase converter of the plurality of single-phase converters, the respective monitoring and control unit being configured and programmed to determine the direction of rotation and a speed of rotation of the multi-phase electric motor from the actual values of the phase currents.
