Abstract: A controller of a host system executes a method for detecting an external AC electrical device. While an AC charging inlet of the host system is electrically connected to the device via different vehicle-to-live (V2L) and jump-charge connections, the controller detects a control pilot voltage and a proximity voltage. When the control pilot voltage is 0V, the controller determines whether entry conditions are satisfied indicative of a desire to offload power from the host system to the device. When the entry conditions are satisfied, the proximity or control pilot voltage are modulated to generate a modulated voltage signal, which the controller compares to an expected voltage indicative of the device. Power is offloaded to the device when the modulated voltage signal matches the expected voltage.

Abstract: A method of using an adaptive fault diagnostic system for motor vehicles is provided. A diagnostic tool collects unlabeled data associated with a motor vehicle, and the unlabeled data is transmitted to a central computer. An initial diagnostic model and labeled training data associated with previously identified failure modes and known health conditions are transmitted to the central computer. The central computer executes a novelty detection technique to determine whether the unlabeled data is novelty data corresponding with a new failure mode or normal data corresponding with one of the previously identified failure modes or known health conditions. The central computer selects an informative sample from the novelty data. A repair technician inputs a label for the informative sample, and the central computer propagates the label from the informative sample to the associated novelty data. The central computer updates the labeled training data to include the labeled novelty data.
