A vehicle power supply system, a controlled unit is connected to a controllee power supply system that is one of a first power supply system and a second power supply system of the vehicle power supply system. A parameter acquiring unit is connected to a controller power supply system that is another one of the first power supply system and the second power supply system and configured to acquire a parameter indicating a sign of voltage change of the controllee power supply system. An operation setting unit is configured to predict the voltage change of the controllee power supply system in response to the sign indicated by the parameter and set a power supply state of the controlled unit indicating at least one of a number of drive pulses per unit time, a duty ratio, and a drive current so as to obtain a constant output from the controlled unit.
