  • Patent number: 10003112
    Abstract: A battery pack for use with a supply of heat transfer fluid includes a plurality of battery modules arranged in one or more rows, and an elongated backplane positioned between the rows or adjacent to one row. The backplane has external longitudinal surfaces, and includes multiple bus bar assemblies equal in number to the number of battery modules and connected to the external longitudinal surfaces. The elongated backplane defines internal conduits configured to receive heat transfer fluid from the supply and extending along a length of the backplane adjacent to the bus bar assemblies. End plates of the battery modules include negative and positive voltage terminals mating with corresponding electrical connectors of a respective one of the bus bar assemblies. An electrical connection between each bus bar assembly and corresponding voltage terminals is established via a push-to-connect operation, with a finger-proof barrier covering the positive terminal.

  • Patent number: 10001209
    Abstract: Methods of producing an assembly, e.g., a bearing assembly, for a vehicle, with reduced thermal expansion in a linear direction as well as methods for minimizing linear thermal expansion in an assembly, are provided. The assembly has at least two components with substantially different linear coefficients of thermal expansion (CLTEs). The assembly has a lightweight planar metal component (e.g., a housing) with a first CLTE, a second component (e.g., a bearing component) having a second CLTE, and a polymeric composite with a third CLTE. The first CLTE is greater than the second CLTE. The third CLTE is less than or equal to the second CLTE, so that the polymeric composite structure attached to the first planar metal component reduces thermal expansion of the first planar metal component in at least one linear direction and minimizes separation of the second surface of the first planar metal component from the second component.

The processor device executes the instructions to dynamically populate and update the database objects such that key fob codes are dynamically assigned and reassigned to driver identifiers. The subsystem has user-specific configurable settings associated with the driver identifier objects. Selection of an active driver identifier results in the loading of corresponding settings for the subsystem.

  • Patent number: 9995256
    Abstract: An engine includes a cylinder block defining a bank of cylinders having physically adjacent first and second cylinders. The engine also has a gas compressor configured to pressurize an ambient airflow for delivery to the first cylinder and the second cylinder. The engine additionally has intake valves configured to control delivery of the pressurized airflow as a first airstream to the first cylinder and a second airstream to the second cylinder for combustion therein. A firing interval for the two adjacent cylinders results in the first airstream temporally overlapping the second airstream. A charge-air cooler is configured to cool the pressurized airflow prior to delivery thereof to the first and second cylinders and includes a cold-side plenum for discharging the pressurized airflow toward the first and second cylinders. A partition in the cold-side plenum is configured to separate the first airstream from the second airstream and thereby minimize interference therebetween.

  • Patent number: 9995241
    Abstract: Methods and systems are provided for controlling fuel injectors included in a fuel injection system of an internal combustion engine of a vehicle. The fuel injection system includes a fuel rail. The methods and systems measure data for the fuel injector relating fuel injection flow rate and fuel injector energization time at a first rail pressure. The methods and systems transform the measured data using a correlation function t to correlated data relating fuel injection flow rate and injector energization time at a second rail pressure different from the first rail pressure. The methods and systems control the fuel injector using the correlated data relating fuel injection flow rate and injector energization time.

  • Patent number: 9995192
    Abstract: The present invention relates to a crankcase ventilation device for a vehicle and, more specifically, to a crankcase ventilation device for a vehicle, which: prevents a back flow of blow-by gas to a new air inflow valve according to a rise in pressure and a rise in a flow rate inside a crankcase; prevents deterioration in the inside of an engine due to unburned fuel contained in the blow-by gas and minute particles of engine oil, generation of sludge, and an engine failure; and minimizes contamination of an intake system by providing a new air inflow control valve having a nozzle and a diaphragm, so as to block a back flow of the blow-by gas to a new air inflow hose due to an excessive rise in pressure inside the crankcase during a process for re-circulating and re-burning the blow-by gas discharged from the crankcase of the vehicle.

  • Patent number: 9994118
    Abstract: Implementations of the present invention contemplate utilizing a communicative infrastructure represented by a telematics unit of an electric vehicle and a telematics service provider (TSP) communicatively coupled to the telematics unit to control an amount of power reserved for a charging event of the vehicle. Specifically, the TSP utilizes information provided by the telematics unit, electrical power utilities, and electrical power metering devices to determine the characteristics of electrical energy available for charging the vehicle. The TSP can utilize the characteristics of the available energy along with additional information, such as charging preferences established by a subscriber of the TSP and vehicle use schedules, to determine an amount of power to reserve for the charging event. The amount of power reserved for the charging event may be determined based on cost, greenhouse gas emissions, a combination thereof, and on other factors.

  • Patent number: 9995196
    Abstract: A method and system for operating an aftertreatment system of an internal combustion engine is disclosed. A value of a storage efficiency for the lean nitrogen-oxide trap is determined. A value of an exhaust gas temperature is measured upstream of the lean nitrogen-oxide trap. An electric heated catalyst enabling condition may be fulfilled if the storage efficiency of the lean nitrogen-oxide trap is smaller than a threshold value thereof and the value of the exhaust gas temperature upstream of the lean nitrogen-oxide trap is greater than a lower threshold value and less than an upper threshold value. The electric heated catalyst is activated if the enabling condition is fulfilled. An inhibition enabling condition may be fulfilled if the value of storage efficiency is less than a second threshold value and the electric heated catalyst is deactivated and a denitrification of the lean nitrogen-oxides trap is started.

  • Patent number: 9995236
    Abstract: A delay module, based on a base request received for a first loop, sets a delayed base request for a second loop. A first period between the first and second loops corresponds to: a first delay period of an oxygen sensor; and a second delay period for exhaust to flow from a cylinder of an engine to the oxygen sensor. A closed loop module determines a closed loop correction for the second loop based on: the delayed base request for the second loop; a measurement from the oxygen sensor; the closed loop correction for the first loop; and the closed loop correction for a third loop. A second period between the second and third loops corresponds to the first delay period of the oxygen sensor. A summer module sets a final request for the second loop based on the base request plus the closed loop correction for the second loop.

  • Patent number: 9995366
    Abstract: A system for absorbing vibration and transmitting torque from a rotating power source to a rotatable load includes a rotatable driving member configured as an input to be driven by the power source to rotate about an axis of rotation. The system has a cam plate with a cam surface. A spring is configured to extend lengthwise in a radial direction relative to the axis of rotation. The spring is configured to be compressed due to the cam surface during relative rotation of the driving member and a driven member when the cam plate is operatively connected to rotate in unison with said one of the driving member and the driven member. The spring therefore has an effective spring rate dependent upon the cam surface, compression of the spring absorbs torsional vibration of the driving member, and the cam plate.
