Systems and methods are provided that prevent or override a hybrid electric vehicle (HEV) from operating in an engine-on mode or condition when the HEV is coasting, such as when the HEV is traveling on a downhill grade. Regenerative torque is generated by one or more electric motors of the HEV so that the pinion gear of a planetary gear set of a power distribution mechanism operates below an overspeed limit at which hardware failure may occur.
