  • Publication number: 20250121739
    Abstract: Methods and systems for managing power of a hybrid vehicle that includes a fuel cell and a traction battery are described. In one example, cooling of the battery and fuel cell may be adjusted preemptively before the hybrid vehicle reaches high load conditions to extend fuel cell durability over its life span, meanwhile the hybrid vehicle may meet driver demand for a longer period of time while operating at the high load and high ambient temperature conditions.

  • Patent number: 12055112
    Abstract: Systems and methods for operating a vehicle that includes an engine that may be automatically stopped and started are described. In one example, inhibiting of automatic engine stopping and starting may be based on comparing an engine off opportunity and a plurality of auxiliary logic performances. The plurality of auxiliary logic performances may be based on a plurality of auxiliary control routine blocks.

  • Patent number: 12017637
    Abstract: A vehicle includes an engine; an electric machine; a transceiver, programmed to communicate with a server; and a controller, programmed to responsive to identifying a route, obtain road data associated with the route via the transceiver, wherein the road data include locations of stop signs and traffic lights, and identify a sign classification using a sign and traffic light density calculated using a total number of stop signs and traffic lights within a lookahead distance on the route, identify a road type classification using the sign classification, responsive to determining the sign and traffic light density within the lookahead distance is above a threshold indicative of a city road type classification, adjust a drivetrain of the vehicle to reduce engine operation and increasingly propel the vehicle via the electric machine.

  • Patent number: 11979847
    Abstract: Handshaking is performed, by an ego device via a wireless transceiver, with surrounding mobile devices to receive identifiers of the surrounding mobile devices and incoming notification messages from the surrounding mobile devices. Each of the incoming notification messages are sent from a different respective sender device of the surrounding mobile devices and include identifiers of devices seen by the sender device and an indication of whether issues with the devices seen by the sender device were identified by the sender device. An alert is raised responsive to an issue being indicated with the ego device based on the incoming notification messages.

  • Patent number: 11628818
    Abstract: A method and system for operating a vehicle that includes an automatic transmission with a torque converter clutch is described. In one example, the method includes predicting a time that the torque converter clutch will open so that stopping rotation of the engine may be requested before the torque converter clutch is opened. The stopping rotation of the engine is requested to conserve fuel.
