| 1. A power supply control system for a vehicle, comprising:
a supply line system;
a first electric generating means for generating electricity through use of a mechanical drive force of a drive source of
the vehicle, which drives the vehicle to run, wherein the first electric generating means is connected to the supply line
system;
a second electric generating means for generating electricity through use of a heat energy, wherein the second electric generating
means is connected to the supply line system; and
a control means for controlling the first electric generating means and the second electric generating means, wherein:
the control means operates the first electric generating means to generate the electricity when a voltage of the supply line
system is below a first threshold voltage;
the control means stops the first electric generating means when the voltage of the supply line system is equal to or greater
than the first threshold voltage;
the control means operates the second electric generating means to generate the electricity when the voltage of the supply
line system is below a second threshold voltage, which is different from the first threshold voltage; and
the control means stops the second electric generating means when the voltage of the supply line system is equal to or greater
than the second threshold voltage.
