  • Publication number: 20240132147
    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. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.

  • Publication number: 20240088814
    Abstract: When a DC power source fails, the following controls are performed. The normal control is resumed when an inverter input voltage recovers before a standby period elapses after a power failure time. A power source relay is turned off when the standby period elapses without recovery of the voltage. The power source relay is turned on again when a power source relay off period has elapsed from a turn-off time. The normal control is resumed when the inverter input voltage recovers at the turn-on time. The normal control is resumed when the inverter input voltage recovers before the power source relay on period elapses from the turn-on time. The power source relay is turned off, and driving of the actuator is stopped, when the power source relay on period passes without recovery of the voltage.
