The invention provides a torque distribution method and device, equipment and a medium. The method comprises the steps that the torque required by a driver, the upper limit of the economical optimal torque of an engine and the lower limit of the economical optimal torque of the engine are obtained, and the economical optimal torque of the engine is the torque which can be provided when the oil consumption of the engine is the lowest; obtaining the torque size relation between the driver demand torque and the engine economic optimal torque upper limit and the engine economic optimal torque lower limit; according to the torque magnitude relation, the target output torque of the engine and the target output torque of the motor are determined; and the engine is controlled to work according to the target output torque of the engine, and the motor is controlled to work according to the target output torque of the motor. According to the method, oil loss can be reduced, and the vehicle using cost of commercial vehicle users is reduced.
