Abstract
The invention relates to a method for jointly controlling asynchronous machines () of a motor vehicle () having a first asynchronous machine () and a second asynchronous machine () for driving the motor vehicle (); an inverter (), which is designed to supply the first asynchronous machine () and the second asynchronous machine () with a common stator voltage () at a common stator frequency (). The method comprises the steps of determining a specified setpoint drive torque () of the motor vehicle () for a current driving situation of the motor vehicle (); sensing a first rotational speed () of the first asynchronous machine () and a second rotational speed () of the second asynchronous machine (); determining a common operating strategy of the first asynchronous machine () and of the second asynchronous machine () according to the specified setpoint torque () while taking into account the sensed rotational speeds (); and controlling the stator voltage () and the stator frequency () in order to set the drive torques () of the asynchronous machines () according to the operating strategy.
