Abstract: A vehicle power supply system includes a power source control device that executes a process of switching a connection state of a driving circuit to the main power source and an auxiliary power source including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source is resolved. After a voltage decrease of the main power source occurs, a turning-side control device of a steering control unit sets an output-limited state for a turning-side motor.
