20120038324 | DUAL-CHARGER SYSTEM - A dual-charger system operable to facilitate charging a battery with energy regulated by two chargers connected in parallel to the battery where one charger operates according to a voltage regulation mode and the other of the two chargers operates according to a current regulation mode. | 02-16-2012 |
20130342379 | Vehicle Remote Function System and Method - A vehicle remote function system is provided for determining a location of a fob relative to a vehicle. The system includes a controller adapted to be mounted in the vehicle and configured for communication with antennas mounted at different vehicle locations, the controller for use in determining the location of the fob based on ultra-wide band wireless signals transmitted between the antennas and the fob. The controller is configured to locate the fob within one of multiple three-dimensional zones, one of the zones configured to have a non-spherical shape. A method is also provided for use in a vehicle remote function system, the method for determining a location of a fob relative to a vehicle. The method includes transmitting ultra-wide band wireless signals between the vehicle and the fob, and determining the location of the fob within one of multiple three-dimensional zones, one of the zones having a non-spherical shape. | 12-26-2013 |
20140248898 | SYSTEM AND METHOD FOR DETECTING A LOCATION OF A WIRELESS DEVICE - A vehicle system and method is provided for detecting the location of a portable wireless device. The vehicle system includes the portable device and a plurality of base stations positioned about a vehicle. The portable device is configured to transmit a first wireless signal and a second wireless signal indicative of motion data of the portable device. A main base station of the plurality of base stations is configured to determine a first final position of the portable device in response to each of the plurality of base stations successfully receiving the first wireless signal. The main base station is further configured to determine a second final position of the portable device using the first final position and the motion data of the second wireless signal as received at the first base station and after determining that the second base station has not successfully received the second wireless signal. | 09-04-2014 |
20140253287 | Vehicle Remote Function System and Method for Effectuating Vehicle Operations Based on Vehicle FOB Movement - A vehicle remote function system is provided for use in effectuating vehicle operations based on movement of a fob relative to a vehicle. The system may include a controller for determining locations of the fob within zones proximate the vehicle based on ultra-wide band wireless signals transmitted between the antennas and the fob, the zones including a primary zone and secondary zones, each secondary zone at least partially within the primary zone. The controller may be configured to detect a movement of the fob between secondary zones and generate a control signal for use in effectuating a vehicle operation based on the movement detected. A method is also provided which may include transmitting ultra-wide band wireless signals between the fob and the antennas, detecting a movement of the fob between secondary zones, and generating a control signal for use in effectuating a vehicle operation based on the movement detected. | 09-11-2014 |
20140253288 | Vehicle Remote Function System and Method for Determining Vehicle FOB Locations Using Adaptive Filtering - A vehicle remote function system is provided for determining locations of a fob relative to a vehicle. The system may include a controller configured for communication with antennas mounted at different locations in the vehicle, the controller for use in determining locations of the fob based on ultra-wide band wireless signals transmitted between the antennas and the fob. The controller is configured to use a first filtering of the wireless signals to determine an initial location of the fob, and a second filtering of the wireless signals to determine a subsequent location of the fob. A method is also provided which may include transmitting ultra-wide band wireless signals between the fob and antennas mounted in the vehicle, using a first filtering of the wireless signals to determine an initial location of the fob, and using a second filtering of the wireless signals to determine a subsequent location of the fob. | 09-11-2014 |
20140308971 | Vehicle System for Detecting a Three-Dimensional Location of a Wireless Device - A vehicle system is provided with a portable device that is configured to provide a wireless signal. The vehicle system includes at least three base stations for being positioned about a vehicle within a first plane and a fourth base station for being positioned within the vehicle and vertically offset from the first plane to define a second plane with two of the at least three base stations. Each base station is configured to receive the wireless signal and to generate a message indicative of a time of flight of the wireless signal. The fourth base station is further configured to determine a three-dimensional location of the portable device based on the message generated by each base station. | 10-16-2014 |
20150208207 | WIRELESS DEVICE LOCALIZATION - A vehicle system is provided with a portable device configured to provide a wireless signal and at least three base stations for being positioned about a vehicle. Each base station being configured to receive the wireless signal and to generate a message indicative of a time of flight of the wireless signal. The vehicle system also includes a main base station for being positioned within the vehicle and configured to determine a general location of the portable device within one of a plurality of zones about the vehicle and to determine a three-dimensional location of the portable device based on the message using a first estimation in response to the portable device being located in a first zone. | 07-23-2015 |
20150329018 | VEHICLE SEATING SYSTEM - A system and method for controlling movement of a seat in a vehicle includes a lower seat assembly and an upper seat assembly adjustable relative to the lower seat assembly. An actuator assembly pivotally attached between the lower seat assembly and upper seat assembly selectively adjusts the upper seat assembly relative to the lower seat assembly between at least one upright position and at least one folded position. A control unit selectively actuates a motor and the actuator assembly to control movement of the upper seat assembly relative to the lower seat assembly. The control unit adjusts the position of the actuator assembly to releasably secure the motor in response to the position value detected by a sensor assembly to place the upper seat assembly in position relative to the lower seat assembly. | 11-19-2015 |
