A vehicle includes a system that performs a method of derating a motor of the vehicle. The system includes a timer and a processor. The processor is configured to start the timer when a temperature of a stator of the motor exceeds a high temperature threshold, select a blend ratio based on a time value on the timer, determine, using the blend ratio, an intermediate derating curve for the motor by interpolating between a first derating curve associated with a first target temperature and a second derating curve associated with a second target temperature greater than the first target temperature, and derate the motor along the intermediate derating curve.
