The invention belongs to the technical field of extended-range electric vehicles, and discloses a torque determination method, device and equipment, a storage medium and a product. The corrected maximum allowable discharge power of the battery is calculated according to the operation information corresponding to the vehicle to be detected, then the maximum allowable discharge power from the battery to the driving end is calculated according to the corrected maximum allowable discharge power of the battery, and then the maximum allowable torque from the gearbox to the driving end is calculated according to the operation information. And calculating the maximum allowable driving torque of the whole vehicle according to the maximum allowable discharge power from the battery to the driving end, the maximum allowable torque from the gearbox to the driving end, the maximum allowable torque of the motor and the torque ratio of the gearbox. The maximum allowable driving torque of the whole vehicle is calculated according to the maximum allowable discharge power from the battery to the driving end, the maximum allowable torque from the gearbox to the driving end, the maximum allowable torque of the motor and the torque ratio of the gearbox, the maximum allowable driving torque of the extended-range electric vehicle can be accurately calculated, and the required torque of the driving end of the whole vehicle is effectively controlled; the safety of the whole vehicle is ensured.
