VEHICLE POWER SUPPLY SYSTEM AND CONTROL METHOD OF VEHICLE POWER SUPPLY SYSTEM

The abstract describes a vehicle power supply system that includes a power source control device responsible for switching the connection state of a driving circuit between the main power source and an auxiliary power source. The system transitions to a backup state when the voltage of the main power source decreases and returns to a normal state once the voltage decrease is resolved. Additionally, a turning-side control device of a steering control unit limits the output of a turning-side motor when a voltage decrease occurs, with the limitation being lifted once the power source control device completes the switching process.

Original Abstract Submitted

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.
