Abstract: A power supply system is installed in a vehicle having an autonomous driving mode. The power supply system includes a first load circuit connected to a first load that operates using electric power from a main battery; a second load circuit connected to a second load that operates using electric power from the main battery or an additional battery and that is necessary to continue the autonomous driving mode; and a first circuit connection/disconnection mechanism provided on a power supply line for electrically connecting the first load and the second load, the first circuit connection/disconnection mechanism that electrically connects or disconnects the first load circuit to or from the second load circuit. The first load circuit is located on an upstream side of the first circuit connection/disconnection mechanism. A current path on a downstream side of the first circuit connection/disconnection mechanism includes a first path for allowing a current flowing from the first load circuit to the first circuit connection/disconnection mechanism to flow from a branch point located on the downstream side of the first circuit connection/disconnection mechanism to the second load, and a second path for allowing the current to flow from the branch point to the additional battery. A current value allowed for conduction through the first path is higher than a current value allowed for conduction through the second path. The second load circuit includes the second load and a third load that is not necessary for traveling in the autonomous driving mode. The third load is connected to the second path between the branch point and the additional battery.

Abstract: In a power supply system, a voltage monitor detects a voltage of output power output from a DC/DC converter. A step-down unit steps down the voltage of the output power and supplies the output power to a load. A distributor control unit controls the step-down unit based on the voltage detected by the voltage monitor. In a power satisfaction state in which the voltage detected by the voltage monitor is equal to or higher than a predetermined threshold voltage, the distributor control unit controls the step-down unit to step down the voltage of the output power and supply the output power to the load. In a power shortage state in which the voltage detected by the voltage monitor is less than the threshold voltage, the distributor control unit controls the step-down unit to supply the output power to the load without stepping down the voltage of the output power.

Abstract: A controller of a power supply control is configured to: in response to a failure of a main power supply being detected, execute a fail-safe control in which a connector is interrupted and electric power from a backup power supply is supplied to a second load; in response to a state value indicating a charging state of the backup power supply decreasing to a first threshold during the fail-safe control, execute an advance notice process for giving a user advance notice that a vehicle will be stopped; and in response to the state value decreasing to a second threshold which is smaller than the first threshold and which indicates a safety limit of the backup power supply, execute a power supply stop process for stopping supply of the electric power from the backup power supply.
