Adaptive control method for electric motor load, and outdoor operation vehicle

An outdoor working vehicle, comprising:

• a vehicle frame;
• a working mechanism attached to the vehicle frame, the working mechanism comprising a working motor and an output assembly configured to be driven by the working motor to perform a specific functional operation;
• and
• a controller assembly configured to control an operation state of the working motor;
• wherein
• the working motor has a plurality of operating parameters, and the controller assembly has a plurality of control strategies for the working motor, the plurality of control strategies correspondingly matching the plurality of operating parameters;
• the controller assembly comprises a collection unit, an identification unit, a storage unit and a control unit;
• the collection unit is configured to collect at least one of the operating parameters of the working motor during operation of the working motor;
• the identification unit is configured to identify a load condition of the working motor based on the collected operating parameter;
• the storage unit is configured to pre-store a correspondence between the operating parameters of the working motor and a load change and pre-store an upper boundary threshold and a lower boundary threshold of the operating parameter corresponding to a load;
• and
• the control unit is configured to determine whether a detected actual load matches an actual operating parameter of the working motor based on the correspondence stored in the storage unit, and adjust performance parameters of the working motor by using a matched control strategy, in response to the actual operating parameter not falling within a range formed by a preset upper boundary threshold and a preset lower boundary threshold of the operating parameter corresponding to the actual load.
