Abstract: In exemplary embodiments, methods, systems, and vehicles are provided for controlling operation of a vehicle in a fuel economy mode. In one embodiment, a vehicle is includes a battery, a generator, and a control system for controlling operation of the vehicle in a fuel economy mode, the control system including: (i) one or more current sensors configured to measure a battery current of the battery; and (ii) a processor coupled to the one or more current sensors and configured to at least facilitate controlling operation of the battery and the generator in the fuel economy mode utilizing a dynamic voltage threshold that is adjusted based on a comparison of the battery current with a baseload current threshold.

Abstract: An example method includes receiving a wakeup request from a device from a vehicle. The wakeup request indicates that the device desires to perform a task that consumes electrical power from a battery of the vehicle. The method further includes assigning a priority to the wakeup request. The method further includes queuing the wakeup request according to a wakeup schedule. The method further includes, responsive to a current time satisfying the wakeup schedule, performing the task based at least in part on the priority.

Abstract: A method and system for downloading and installing software to a vehicle that includes a battery and vehicle electronics. The system includes a vehicle communications device that receives an anticipatory signal indicating that software is ready or will be ready for wireless download to the vehicle. In response to the anticipatory signal, the method and system determine whether the vehicle is in a state and/or the battery has enough energy for wireless download of the software package, installation of the software, or both. If the vehicle is not in such a state or the battery does not have the requisite energy, then changes to battery charging parameters may be made in preparation of the software download and/or installation.

Abstract: A method and system are provided for controlling a vehicle capable of operating in a fuel economy mode in which fuel is conserved by limiting operation of an engine. The method includes obtaining forecast temperatures for one or more dates and comparing the forecast temperature for each date to a threshold temperature. The method further includes generating a control signal if the forecast temperature for a given date meets a predetermined condition relative to the threshold temperature. The control signal is configured to disable fuel economy mode of the vehicle. The method further includes disabling the fuel economy mode of the vehicle in response to receiving the control signal. By disabling fuel economy mode at selected temperatures, the method and system allow the vehicle to preserve a sufficient state of charge in the vehicle battery for cold starts.
