  • Trailer to vehicle integral current draw management
    Patent number: 11453261
    Abstract: In accordance with an exemplary embodiment, an autonomous system is provided that includes: a tow vehicle, a trailer, and a control system. The tow vehicle has a vehicle battery. The trailer is coupled to the tow vehicle, and has a trailer battery. The control system includes a sensor and a processor. The sensor is configured to at least facilitate measuring a state of charge of the trailer battery. The processor is coupled to the sensor, and is configured to at least facilitate selectively providing current from the tow vehicle to the trailer based on the state of charge of the trailer battery.

  • Wiring prognostics system for vehicles
    Patent number: 11355953
    Abstract: A system for a vehicle includes a battery of the vehicle, a plurality of switches connected to the battery, and a plurality of subsystems of the vehicle connected to the battery via the switches and wires. The system includes a controller configured to control the switches and the subsystems, and to identify a variation in a rate of change of current characteristic in frequency domain for a current loop including one of the switches, one of the subsystems, and a plurality of the wires. The controller is configured to determine integrity of the plurality of the wires and connections of the wires in the current loop based on the variation in the rate of change of current characteristic for the current loop.
