The invention provides a torque distribution method, device and equipment which are applied to a hybrid electric vehicle, and the method comprises the steps that multiple output torques of the current engine rotating speed under preset engine efficiency are determined from the mapping relation of the engine rotating speed, the value range of the output torques of an engine and the engine efficiency; according to the current state of charge of the battery, the co-state variable and at least one candidate output torque meeting a preset condition in the plurality of output torques, obtaining the respective energy value of the at least one candidate output torque by using a relation model; and a target energy value smaller than a first preset threshold value is selected from the energy values of the multiple output torques, and the actual output torque of the current engine is determined based on the output torque corresponding to the selected target energy value. By means of the method, the accurate distribution result can be obtained when the PMP algorithm is used for distributing the output torque of the engine.
