A controller comprises one or more processors associated with a first and second power inverter for the drive unit of an electric vehicle. Computer-readable media for the one or more processors are each configured to store computer-executable instructions configured to cause the one or more processors to apply a same fault action to the first power inverter and the second power inverter responsive to a fault associated with an inverter chosen from the first power inverter and the second power inverter, wherein the same fault action includes applying equalized torque to each axle operatively coupled to the drive unit. The controller may be contained in a dual power inverter module which comprises a DC link capacitor connectable to a source of high voltage direct current electrical power, and first and second power inverters electrically connected to the DC link capacitor. The controller may be part of an electric vehicle which los comprises a high voltage DC battery and first and second electric motors mechanically coupled to rotate at least one set of axles.
