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. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.

Vehicle power supply system and control method of vehicle power supply system

A steering control device includes a first reaction force control circuit and a second reaction force control circuit. Each of the first reaction force control circuit and the second reaction force control circuit are configured to control a reaction force motor, to execute, at a starting time, a preparation process including a process that requires the steering wheel to automatically rotate through the reaction force motor, and to store, at a time of execution completion of the preparation process, information indicating whether the preparation process has been normally completed. In a case where the first reaction force control circuit has been reset, when the information indicates that the preparation process has been normally completed, the first reaction force control circuit that has been rest is configured to not execute the preparation process at a time of restarting after completion of the reset.
