The invention discloses a vehicle power take-off torque control method, device and equipment and a storage medium, and relates to the technical field of new energy commercial vehicles, and the method comprises the steps: obtaining a rotating speed value, a proportional integral coefficient and a proportional rotating speed difference value; calculating a proportional control torque and an integral control torque based on the rotating speed value, the proportional-integral coefficient and the proportional rotating speed difference value; and based on the rotating speed value, the proportional control torque and the integral control torque, the vehicle power take-off torque is adjusted to control the vehicle to maintain constant-speed driving. The proportional control torque and the integral control torque are calculated according to the proportional-integral control principle, operation is easy, more calibration energy is saved in practical application, therefore, overshoot is limited, the vehicle power take-off torque is accurately adjusted, constant rotating speed control over the motor in the driving power take-off mode is achieved, road surface working conditions and load changes are automatically adapted, and the power take-off efficiency is improved. A driver does not need to manually adjust an accelerator and a brake pedal, the operation burden of the driver is effectively reduced, and the vehicle use performance and working efficiency are remarkably improved.
