  • Publication number: 20190056234
    Abstract: A method for planning and adapting a recommended travel route to a route destination for a vehicle having various subsystems includes identifying the route destination and receiving vehicle health management (VHM)/state of health (SOH) information for each subsystem. The vehicle with a controller programmed to execute the method is also disclosed. The method includes calculating route characteristics of candidate travel routes to the destination using the VHM information and determining, from among the candidate travel routes, travel routes for which the characteristics meet a respective threshold requirement. Thereafter, the controller executes a control action by displaying a candidate route meeting the threshold requirements. An occupant is prompted to revise the mission requirements when no candidate route exists. A default route to a designated parking location or repair depot may be displayed when none of the candidate routes meet the threshold requirements.

  • Publication number: 20190054838
    Abstract: Disclosed herein are a system and method of selecting range for an electric device having a rechargeable energy storage unit. The system includes a controller having a processor and tangible, non-transitory memory on which is recorded instructions. A charging unit is configured to charge the rechargeable energy storage unit when plugged to the charging unit. An operator is requested to enter a selected range for the electric device. The controller is configured to determine if the selected range is less than a predetermined maximum range. If the selected range is less than the predetermined maximum range, the selected range is converted to a selected energy consumption based on a driving model of the operator. A target voltage is determined based on the selected energy consumption and predetermined parameters of the charging unit. The rechargeable energy storage unit is charged to the target voltage, via the charging unit.
