  • Publication number: 20170214258
    Abstract: A disconnect architecture for use with a system having a battery pack and positive and negative bus rails includes a mid-pack low-power (LP) relay, a fuse, semiconductor switches, and a sequencer circuit. The mid-pack LP relay is positioned between the rails at a mid-stack point of the battery pack, and divides a voltage across the battery pack when commanded open. The fuse is positioned between the mid-pack LP relay and the positive bus rail, and opens in response to a dead short condition of the system. The semiconductor switches are positioned in electrical parallel with the mid-pack LP relay. The sequencer circuit selectively turns on the semiconductor switches and thereby coordinates a flow of electrical current through the semiconductor switches and the mid-pack LP relay in response to a detected partial short condition of the system. A system includes the battery pack, bus rails, and disconnect architecture.

  • Patent number: 9714617
    Abstract: A system according to the principles of the present disclosure includes an engine cranking module and a throttle control module. The engine cranking module determines whether an engine is cranking based on at least one of an input received from an ignition system and engine speed, and generates a signal indicating whether the engine is cranking. The throttle control module selectively adjusts a throttle of the engine to a fully closed position when the signal indicates that the engine is cranking.

  • Patent number: 9714625
    Abstract: A system according to the principles of the present disclosure includes an air/fuel ratio determination module and an emission level determination module. The air/fuel ratio determination module determines an air/fuel ratio based on input from an air/fuel ratio sensor positioned downstream from a three-way catalyst that is positioned upstream from a selective catalytic reduction (SCR) catalyst. The emission level determination module selects one of a predetermined value and an input based on the air/fuel ratio. The input is received from a nitrogen oxide sensor positioned downstream from the three-way catalyst. The emission level determination module determines an ammonia level based on the one of the predetermined value and the input received from the nitrogen oxide sensor.

  • Patent number: 9716941
    Abstract: An assembly for use in a designated listening area includes a body having a frame rail supporting or framing the body laterally adjacent to the designated listening area, and defining a cavity, and a subwoofer assembly having subwoofer speakers each defining a smaller second air volume. The subwoofer assembly is mounted to the frame rail such that the second air volumes are contiguous with and open into the first air volume. A sealing mechanism enclosed the first air volume within the cavity. A method includes providing a subwoofer assembly having subwoofer speakers defining respective second air volumes, mounting the subwoofer assembly to a frame rail laterally adjacent to the designated listening area such that the respective second air volumes are contiguous with and open into the first air volume, and sealing the first air volume with a sealing mechanism.

  • Patent number: 9716758
    Abstract: A system for reduction of discontinuous-receive (DRx) transmissions for a network access device (NAD) of a telematics unit of a telematics-equipped vehicle includes: the telematics unit, configured to determine whether vehicle ignition of the telematics-equipped vehicle is on or off, the telematics unit further comprising the NAD, the NAD being configured to communicate with a network entity to perform a periodic updating procedure; the network entity, configured to communicate with the NAD for performance of the periodic updating procedure. The NAD and the network entity are further configured to reduce a frequency at which the periodic updating procedure is performed for the NAD in a DRx state relative to the frequency at which the periodic updating procedure is performed for the NAD in a vehicle ignition-on state.

  • Patent number: 9714059
    Abstract: A splitter system for a vehicle includes a splitter body having a first splitter body. The vehicle includes a vehicle body arranged along a longitudinal body axis and having a first vehicle body end configured to face oncoming ambient airflow. The splitter body is moveably mounted at the first vehicle body end and generates an aerodynamic downforce on the first vehicle body end when the vehicle is in motion. The splitter system also includes a mechanism configured to selectively translate the splitter body along the longitudinal body axis away from the first vehicle body end into the incident airflow and toward the first vehicle body end out of the incident airflow. The translation of the splitter body by the mechanism in turn adjusts the aerodynamic downforce generated by the splitter body on the first vehicle body end.

  • Patent number: 9714597
    Abstract: A mixer includes a plurality of blades extending along a longitudinal axis. The blades are arranged in a single row, and are axially spaced from each other along a transverse axis. Each of the blades defines a window. Each of the blades includes an upstream portion, and a downstream portion. Each of the blades includes a bend at the window that forms an interior blade angle between its respective upstream portion and its respective downstream portion. The single row of the blades is arranged to include a first group of blades and a second group of blades. The interior blade angle of each of the blades in the first group faces in a first axial direction along the transverse axis. The interior blade angle of each of the blades in the second group faces in a second axial direction along the transverse axis.

  • Patent number: 9714530
    Abstract: An inertia locking mechanism for a bin having a bin lid and subjectable to an applied force resulting in an acceleration includes a housing attachable to the bin, a bracket attachable to the bin lid and having a locking feature, a locking pin, a biasing member, and a trigger. The locking pin is linearly moveable in the housing. The trigger has a triggering mass and is connected to the housing via a trigger pivot. The triggering mass is offset from the trigger pivot such that the triggering mass applies a torque to the trigger when the acceleration occurs in each of the front, rear, left, and right directions. The trigger is configured to release the locking pin when the acceleration exceeds a threshold acceleration such that the biasing member urges the locking pin into the locking feature of the bracket to lock the bin lid in a closed position.
