    Abstract: The concepts include a user support system in the form of a microphone, a visual display arranged in a vehicle cabin, and a controller. The controller includes an instruction set that is executable to receive, via the microphone, a voice-based request from a user, and employ a virtual assistant to determine a user interaction in real time and to determine a specific intent for the voice-based request, including capturing metadata. A user interaction routine determines a user interaction parameter associated with the virtual assistant based upon the voice-based request from the user. A user sentiment analysis routine determines a user satisfaction parameter associated with the virtual assistant based upon the voice-based request from the user. The controller responds in real-time to the voice-based request based upon the user satisfaction parameter and the user interaction parameter that are associated with the virtual assistant.

  • Publication number: 20240092175
    Abstract: Presented are intelligent vehicle systems for thermal event mitigation during vehicle towing, methods for making/using such systems, and vehicles equipped with such intelligent control systems. A method of operating a host vehicle includes a resident or remote vehicle controller verifying the host vehicle is an incapacitated state. Responsive to the incapacitation of the host vehicle, the controller detects the host vehicle being towed by a tow vehicle and identifies a wireless-enabled portable computing device (PCD) within a predefined range of the host vehicle. Responsive to the host vehicle being towed, the controller determines if the wireless-enabled PCD is on the tow vehicle while towing the host vehicle. Upon detection of a thermal event in at least one battery cell in the host vehicle's battery system while the host vehicle is being towed, the controller responsively commands a resident vehicle subsystem to execute a control operation to mitigate the thermal event.
