Method and computing unit for controlling an electric drive with overmodulation compensation

A computing unit for controlling an electric drive, the computing unit comprising:

• a processor unit configured to divide the electric drive into at least a first subsystem to be controlled having a first control range and a second subsystem to be controlled having a second control range, the first subsystem and the second subsystem having a shared stator and driving a shared rotor of the electric drive;
• a first interface configured to acquire a control vector for controlling the electric drive;
• and
• a second interface configured to detect a first control value in the control range of the first subsystem to be controlled and to detect a second control value in the second control range of the second subsystem to be controlled at a time when a control vector is acquired,
• wherein the computing unit is configured to assign the acquired control vector to the first subsystem and to the second subsystem to control the electric drive in a specific ratio, such that the first control value does not exceed a maximum control range of the first subsystem and/or the second control value does not exceed a maximum control range of the second subsystem.
