  • Publication number: 20150039180
    Abstract: In a vehicle door assembly, controllers processes signals from an extension force sensor and a retraction force sensor to control a door handle. As a motor retracts the handle, a swing arm in the vehicle door presses against the retraction force sensor causing the handle controller to stop the motor. Pushing on the retracted handle presses the swing arm against the retraction force sensor a second time causing the controllers to operate the motor and extend the handle. As the handle extends, the swing arm presses against the extension force sensor and the handle controller stops the motor as the handle is fully extended. Subsequently, a hand pulling on the door handle presses the swing arm against the extension force sensor a second time causing the controllers to unlatch a latch holding the vehicle door shut, and thereby allow the vehicle door to open.

  • Patent number: 8933661
    Abstract: An apparatus and method efficiently integrating inductive and conductive charging systems, including embodiments directed towards enabling user selection of either, or both, of conductive and inductive charging. Conductive charging and inductive charging both have, in certain contexts or when judged by different criteria, advantages over the other. Systems and methods relying on one or the other would not have as wide-spread value to a user with opportunities to access both types of charging modalities.

  • Patent number: 8932739
    Abstract: A battery pack, or battery pack module, is provided that is configured to respond to a short circuit of moderate current in a manner that minimizes the risk of an initial thermal runaway event propagating throughout the battery pack/battery pack module. In general, the battery pack/battery module allows pre-selection of which cell of the cells comprising the battery pack/battery pack module will be the last cell to respond to the short circuit. As a result, a thermal isolation barrier may be used to separate the preselected cell from the other cells of the battery pack/battery pack module, thereby minimizing the risk of excessive heating and extensive collateral damage.

  • Patent number: 8935053
    Abstract: Aspects of the disclosure provide for controlling a hood latch using an electrically actuated primary hood latch and an electrically actuated secondary hood latch. To open the hood of the vehicle, a person presses a hood release button. Before attempting to release either the primary hood latch or secondary hood latch, a determination is made whether a vehicle speed of the vehicle is below a minimum vehicle speed threshold. If the vehicle speed is below this threshold, both the primary electrical actuator for the primary hood latch and the secondary electrical actuator for the secondary hood latch are triggered, thereby releasing hood from a closed position into an open position. When the vehicle speed is above this vehicle speed threshold, only the primary electrical actuator for primary hood latch is triggered; leaving the hood in a partially open position held in place by the secondary hood latch.
