Wheeled work vehicle and wheeled mower

A wheeled mower, comprising:

• a vehicle body;
• a walking mechanism, mounted to the vehicle body, comprising walking wheels and a walking motor, comprising a rotor and a plurality of stator windings, for driving the walking wheels;
• a mowing mechanism comprising a mowing blade and a mowing motor for driving the mowing blade;
• a power supply assembly, comprising at least one battery pack, configured to power the walking motor and the mowing motor;
• a temperature acquisition unit at least configured to acquire an operating temperature of the walking motor;
• a driver circuit connected to at least the walking motor to drive the walking motor;
• and
• a controller, electrically connected to the temperature acquisition unit and the driver circuit, configured to output a control signal to the driver circuit so as to control running of the walking motor, when a parameter of the walking motor related to the operating temperature is greater than or equal to a first temperature threshold, control the wheeled mower to enter a failure mode, and, when the operating temperature is less than or equal to a second temperature threshold, control the wheeled mower to exit the failure mode;
• wherein the first temperature threshold is greater than or equal to the second temperature threshold.

A wheeled work vehicle, comprising:

• a vehicle body;
• a walking mechanism, mounted to the vehicle body, comprising walking wheels and a walking motor, comprising a rotor and a plurality of stator windings, for driving the walking wheels;
• a work mechanism for performing a function of the wheeled work vehicle;
• a power supply assembly, comprising at least one battery pack, at least configured to power the walking motor;
• a temperature acquisition unit at least configured to acquire an operating temperature of the walking motor;
• a driver circuit connected to at least the walking motor to drive the walking motor;
• and
• a controller, electrically connected to the temperature acquisition unit and the driver circuit, configured to output a control signal to the driver circuit so as to control running of the walking motor and, when a parameter of the walking motor related to the operating temperature is greater than or equal to a first temperature threshold, control the wheeled work vehicle to issue a warning signal to prompt a user.
