  • Patent number: 12322229
    Abstract: A system and method for estimation method for determining a location of a vehicle digital key wallet includes selecting, by a user, whether to store a digital key wallet in a cloud storage or within a secure telematics unit contained within a vehicle. The digital key wallet is used to initiate an event within the vehicle. A backoffice server stores data including a radio intelligence database and a rule-based vehicle pattern matrix. The digital key wallet is switched to a fallback device based on the status of a communication link with the secure telematics unit, the radio intelligence database, and the rule-based vehicle pattern matrix.
    Type: Grant

  • Patent number: 10960883
    Abstract: A powertrain system for a vehicle is described, and includes an internal combustion engine that is selectively coupled to a driveline. The engine is configured to operate in a coasting mode, wherein the coasting mode includes operating the powertrain system with the engine in an OFF state and decoupled from the driveline. Devices are configured to monitor an output torque request, vehicle speed, and vehicle operating conditions. An executable instruction set monitors the vehicle speed and the output torque request. The engine is controlled to operate in the coasting mode when the output torque request is within the predetermined torque region and the vehicle speed is greater than a minimum speed threshold. The engine is controlled to discontinue operating in the coasting mode in response to the output torque request being outside the torque region of the vehicle speed being less than a minimum speed threshold.
