The invention discloses a hybrid vehicle torque control method, device and equipment and a storage medium, and relates to the technical field of vehicle control, the method comprises the steps that a hybrid vehicle is tested and calibrated, a two-dimensional calibration table is obtained, and the two-dimensional calibration table comprises a first calibration table, a second calibration table, a third calibration table and a fourth calibration table; calculating an engine target torque of the hybrid vehicle based on the two-dimensional calibration table; determining the target torque of a driving motor of the hybrid vehicle according to the wheel end torque required by the driver and the target torque of the engine; and performing torque control on an engine and a driving motor of the hybrid vehicle based on the engine target torque and the driving motor target torque. According to the method, the engine target torque of the hybrid vehicle is calculated on the basis of the two-dimensional calibration table obtained after the hybrid vehicle is tested and calibrated, then more accurate torque control is conducted on the hybrid vehicle on the basis of the engine target torque, and therefore the engine ignition efficiency of the hybrid vehicle is improved.
