Patent attributes
An electrical system for a vehicle may include a main power supply and a power supply controller electrically connected to the main power supply and configured to selectively electrically connect the main power supply to, and disconnect the main power supply from, a vehicle subsystem. The electrical system may also include a supervisor power supply controller configured to receive signals indicative of an operational status of the vehicle, and determine, based at least in part on the signals, expected signals associated with operation of a plurality of vehicle subsystems. The supervisor power supply controller may also receive signals associated with operation of a vehicle subsystem, and determine that the signals associated with operation of the vehicle subsystem are indicative of a fault. The supervisor power supply controller may cause the power supply controller associated with the vehicle subsystem to disconnect the vehicle subsystem from the main power supply.
