Warm-up method for machine system

A warm-up method for a machine system including a plurality of machine components, a plurality of machine sensors each configured to sense a temperature of a respective one of the machine components, and a processing unit electrically connected to the machine component and the machine sensor, the machine component being a transmission machine component, the method comprising steps of:

• A) for each of the machine components, deriving, by the processing unit, a target temperature corresponding to the machine component based on at least one of plural historic machine temperatures of the machine component that were sensed by the corresponding one of the machine sensors respectively at plural past time points, so that a plurality of target temperatures corresponding respectively to the machine components are determined;
• B) with respect to each of the machine components, activating, by the processing unit, the machine component to execute a warm-up operation for warming up the machine component;
• C) determining, by the processing unit, whether the machine components are all warmed up based on the plurality of target temperatures thus determined and the temperatures respectively of the machine components that are currently sensed by the machine sensors;
• D) when it is determined that the machine components are all warmed up, making, by the processing unit, the machine components not execute the warm-up operation by stopping each of the machine components that is currently executing the warm-up operation from continuing to execute the warm-up operation;
• E) when it is determined that only a portion of the machine components is warmed up, making, by the processing unit, the portion of the machine components not execute the warm-up operation;
• and
• F) repeating step C) after step E),
• wherein step A) includes sub-steps of:
• A-1) selecting at least one adopted time point from the plural past time points, wherein each of the machine components was at work at each of the at least one adopted time point, and wherein for each of the machine components, the historic machine temperature sensed at any of the at least one adopted time point does not exceed a working-temperature threshold associated with the machine component;
• A-2) for each of the machine components, selecting a temperature subset from the historic machine temperatures of the machine component, wherein the temperature subset includes at least one of the historic machine temperatures that corresponds to the at least one adopted time point, and wherein the temperature subset does not include any one of the historic machine temperatures that exceeds a machine-temperature threshold corresponding to the machine component;
• and
• A-3) for each of the machine components, deriving the target temperature corresponding to the machine component based on the temperature subset for the machine component.
