2. The vehicle power take-off control method according to claim 1, further comprising, after the sending of the loading device non-unloading information alert to the terminal: and returning to continuously judge whether the torque of the output shaft of the power takeoff is smaller than or equal to a torque threshold.
3. The vehicle power take-off control method according to claim 2, characterized by further comprising, after the delay time period is equal to a first time period threshold: if the power take-off is in the combined state, returning to continuously judge whether the power take-off is in the disconnected state.
4. A vehicle power take-off control device for implementing a method according to any one of claims 1 to 3, comprising: the first main module is used for determining that the working state of the power takeoff reaches the withdrawal power taking condition; the second main module is used for sending information that the loading equipment is not unloaded to the terminal if the torque of the output shaft of the power takeoff is larger than a torque threshold; the third main module is used for controlling the power takeoff to be disconnected if the torque of the output shaft of the power takeoff is smaller than or equal to a torque threshold value; and the fourth main module is used for sending a power takeoff closing working state signal to the intelligent information terminal when the time delay duration is equal to the first time duration threshold value and the power takeoff is in a disconnection state, so that the engine enters the power takeoff closing working state.
5. An electronic device, comprising:
at least one processor, at least one memory, and a communication interface; wherein,
the processor, the memory and the communication interface are communicated with each other;
the memory stores program instructions executable by the processor, the processor invoking the program instructions to perform the method of any of claims 1-3.
6. A non-transitory computer readable storage medium storing computer instructions that cause the computer to perform the method of any one of claims 1 to 3.
