Abstract: A method for efficient autonomous driving planning includes receiving a current driving-scene data and a predicted driving-scene data. The current driving-scene data is indicative of a current driving scene around a host vehicle. The predicted driving-scene data is indicative of a predicted driving scene around the host vehicle. The predicted driving scene around the host vehicle is different from the current driving scene around the host vehicle. The method further includes converting the current driving-scene data and the predicted driving-scene data into a first scene-graph and a second scene-graph, respectively. The method further includes determining a plurality of scene change metrics using the first scene-graph and the second scene-graph. The method further includes selecting between a first trajectory planning process and a second trajectory planning process based on the plurality of scene change metrics.

Abstract: A method for adjusting state of charge (SOC) limits aboard a motor vehicle having a propulsion battery pack includes receiving a pre-drive information set via a host computer and identifying, from the pre-drive information set, a probability that the motor vehicle is about to embark on a road trip. The road trip is a drive event in which the motor vehicle will travel outside of a predetermined area. The method further includes expanding the SOC limits of the propulsion battery pack when the motor vehicle is about to embark on the road trip, such that a total SOC window of the propulsion battery pack is increased for a duration of the road trip.

Abstract: An electric vehicle includes a system performing a method of charging a battery of the electric vehicle. The system includes an electrical motor having a rotor and a plurality of windings. The vehicle is turned off to allow the rotor to come to rest at an initial rotor position. The processor controls a current through the motor to rotate the rotor to locate a boundary of an electrical lash region associated with the rotor, determines a selected winding of the plurality of windings having a phase vector located close to the electrical lash region, deactivates the selected winding, controls flow of a first current through the motor with the selected winding deactivated to rotate the rotor towards a direction of the selected winding, and controls flow of a second current from a charging station to the battery through the electric motor with the rotor rotated towards the selected winding.
