Method of controlling mechanical mechanisms of electronic device for peak power/current reduction

An electronic device, comprising:

• a plurality of mechanical mechanisms, including at least a first mechanical mechanism and a second mechanical mechanism;
• and
• a control module, electrically connected to at least the first mechanical mechanism and the second mechanical mechanism, comprising:
• a first controller, arranged for driving the first mechanical mechanism by applying a first control signal to the first mechanical mechanism;
• a second controller, arranged for driving the second mechanical mechanism by applying a second control signal to the second mechanical mechanism;
• and
• an output controller, comprising:
• a first comparing unit, arranged for comparing the first control signal with a first predetermined threshold, and accordingly generating a first comparison result;
• and
• an adjusting unit, arranged for selectively adjusting the second control signal according to at least the first comparison result.

A non-transitory machine-readable medium, storing a program code, when executed by a processor, causing the processor to perform following steps:

• driving a first mechanical mechanism of an electronic device by applying a first control signal to the first mechanical mechanism;
• driving a second mechanical mechanism of the electronic device by applying a second control signal to the second mechanical mechanism;
• comparing the first control signal with a predetermined threshold, and accordingly generating a comparison result;
• and
• selectively adjusting the second control signal according to at least the comparison result.
