1. A vehicle system comprising:

  • a processing device programmed to monitor a vehicle battery, determine a vehicle location and orientation according to an antenna field pattern, predict a vehicle maneuver associated with the vehicle location, and determine whether the vehicle battery has sufficient charge for a vehicle to execute the predicted maneuver;

    wherein the processing device is programmed to perform at least one preparatory action if the vehicle battery lacks sufficient charge for the vehicle to execute the predicted maneuver,wherein the processing device is programmed to determine the vehicle location by comparing the antenna field pattern to a plurality of antenna profiles stored in a profile database, matching the antenna field pattern to at least two of the plurality of antenna profiles stored in the profile database, and selecting the vehicle location by prompting a vehicle occupant to select the vehicle location from a list of possible vehicle locations, wherein each possible vehicle location is associated with one of the plurality of antenna profiles that matched the antenna field pattern,wherein the antenna field pattern is based on signals transmitted from multiple antennas and arriving at the vehicle location from different directions and wherein the processing device is programmed to determine the vehicle orientation according to the directions from which the signals are received.
