at a component-side, the smart power supply interface module being configured to connect with the component function module through a component-side BAT line, a GND line, a gear trigger signal line, a sensing module signal line and a communication interface;
the smart power supply module being configured to connect with the component function module through an ACC output interface or an ACC enhanced output interface via a gating connection to an ACC interface of the component function module;
the method comprising;
determining whether the smart power supply interface module is properly operating;
if the smart power supply interface module is properly operating, connecting an ACC enhanced interface of the smart power supply interface module with an ACC interface of the component function module;
determining whether the smart power supply interface module is in a sleep mode;
if the smart power supply interface module is not in a sleep mode, using the ACC enhanced output interface of the smart power supply interface module to transfer an electrical level of a BAT to the component function module, thereby causing the component function module to operate properly; and
if the smart power supply interface module is in a sleep mode, setting an electrical level of the ACC enhanced output to be zero (0), thereby causing the component function module to operate in a sleep mode.
