An electric vehicle drive system includes first and second electric motors, first and second torque limiters and a torque splitter. The first and second torque limiters correspond to the first and second electric motors, respectively, and generate respective first and second maximum torques. The torque splitter receives a first input that includes at least a total torque request for the first and second electric motors and the first and second maximum torques and generates at least respective first and second torque requests for the first and second electric motors, wherein the torque splitter is configured to direct a torque request to the second motor only if the first maximum torque is less than a threshold. The torque splitter may generate a zero second torque request if a motor speed of the first electric motor exceeds a threshold.
