The invention belongs to the technical field of automobile control, and particularly relates to a control method and device of a hybrid electric vehicle, a terminal and a medium. The control method of the hybrid electric vehicle comprises the steps that the engine oil water content of a crankcase is monitored; comparing the water content of the engine oil with a first water content threshold value; and when the water content of the engine oil is higher than a first water content threshold value, the power mode of the hybrid power automobile is adjusted to be an engine direct drive mode, in the engine direct drive mode, a drive motor does not drive the hybrid power automobile, and the hybrid power automobile is only driven by an engine. Thus, hardware cost does not need to be additionally increased, other complex changes for an automobile structure are not needed, the purpose of removing water from the engine oil is achieved by adjusting the power mode of the hybrid automobile according to the water content of
