  • Publication number: 20120296518
    Abstract: Methods for diagnosing a fault of an oil piston cooling jets valve of an internal combustion engine are provided. A method includes sensing a pressure value in a main oil gallery and checking whether the oil piston cooling jets valve is commanded in a state for opening a communication between the main oil gallery and an auxiliary oil gallery or in a state for closing the communication. A pressure value in the auxiliary oil gallery is checked to as to whether it exceeds a predetermined threshold value thereof, above which a jet nozzle of the auxiliary oil gallery automatically opens. A fault of the valve is identified if the pressure value in the main oil gallery exceeds the predetermined threshold value by a predetermined quantity and if a pressure value in the auxiliary oil gallery is different than expected on a basis of the state of the valve.

  • Publication number: 20120296555
    Abstract: A method for operating an internal combustion engine includes injecting a quantity of fuel in the engine per engine cycle. A total value of the fuel quantity is evaluated as the sum of a fuel quantity base value and a fuel quantity correction value. The fuel quantity base value is determined based on a requested value of engine torque to be generated in the engine cycle. The fuel quantity correction value is determined based on an engine torque error in a previous engine cycle, which is calculated as a difference between a value of engine torque generated in the previous engine cycle and the requested value of engine torque for the previous engine cycle.

  • Publication number: 20120293314
    Abstract: A vehicle collision warning system and method may be used to detect a potential or impending collision with another vehicle and to send a corresponding warning to the driver. In an exemplary embodiment, the collision warning system uses one or more target vehicle readings (e.g., a relative velocity reading (?v), a target vehicle acceleration reading (aTAR), and a relative distance reading or range (?d)) to solve a unified collision warning algorithm. If the unified collision warning algorithm determines that there is a potential collision with the target vehicle, then the system sends a corresponding warning to the driver.

  • Publication number: 20120293116
    Abstract: An energy conversion system includes a first core section, a tank, a flexible structure, and an output coil. The tank contains a volume of fluid having a high magnetic permeability. The flexible structure is fluidly coupled to the tank and movable from a retracted to an extended position in response to the injection of the fluid from the tank. The output coil is in electrical communication with the first core section. A charging station includes a second core section and an input coil. The first and second core sections are in alignment to define an air gap therebetween. The air gap is reduced when the flexible structure is in the extended position within the air gap such that the flexible structure transmits magnetic flux between the second core section and the first core section. The magnetic flux in the first core section induces electrical current in the output coil.

  • Publication number: 20120286493
    Abstract: A damper mass damper assembly includes a rod, and a casing disposed annularly about the rod and defining a primary fluid chamber therebetween. The rod includes an annular wall that defines a first and a second expansion chamber disposed at a first and a second end of the rod respectively. The rod further defines a first and a second expansion port connecting the first and the second expansion chambers respectively with the primary fluid chamber in fluid communication. As fluid within the primary fluid chamber expands from heating, the fluid may weep into the first and/or second expansion chambers through the first and/or second expansion ports respectively to maintain the integrity of a first and second cap bearing seal, which seal the fluid within the primary fluid chamber.

    Abstract: Systems and methods to determine a state of charge (SOC) of a battery using confidence values. SOC estimations are determined using a voltage-based estimation strategy and a current-based estimation strategy. Confidence values are also generated for the voltage-based SOC estimation and the current-based SOC estimation to quantify the amount of uncertainty associated with the SOC estimations. An overall SOC estimation is determined by comparing the confidence values and selecting the SOC estimation having the least amount of uncertainty.
