    Abstract: An engine control system for a vehicle includes a timer module, a stochastic pre-ignition (SPI) mitigation module, and a boost control module. The timer module tracks a period of operation of an engine where vacuum within an intake manifold is less than a first predetermined vacuum. The SPI mitigation module generates an SPI signal when the period is greater than a predetermined period and the vacuum is less than a second predetermined vacuum. The second predetermined vacuum is less than the first predetermined vacuum. The boost control module reduces output of a turbocharger in response to the generation of the SPI signal.

  • Patent number: 9299334
    Abstract: A sound source detecting system that detects a predetermined sound source on the basis of sounds collected by sound collectors includes: a noise extracting unit that extracts a noise from signals of the collected sounds; and a noise suppressing unit that suppresses a signal component of the noise extracted by the noise extracting unit from the signals of the collected sounds. The sound source detecting unit detects a location of the predetermined sound source, such as an approaching vehicle, using information about the sounds having the signals of which the noise is suppressed.

  • Patent number: 9274873
    Abstract: Various embodiments include a method and system for high-volume distributed script error report handling. An error report group threshold may be obtained. The error report group threshold may be determined by available computing resources, at an error facility, to receive error reports. A subset of current user terminals with representative user terminal environments may be identified. The subset may have a cardinality less than the error report group threshold. Members of the subset may be notified to report errors for a distributed program.

  • Patent number: 9222427
    Abstract: A system includes a parameter module that determines at least one of a position of a throttle and a load of an engine. A cylinder status module generates a status signal indicating an activation status of each cylinder of the engine. The cylinder status module determines whether one or more of the cylinders are activated. A first pressure prediction module, when all of the cylinders are activated, predicts first intake port pressures for the cylinders of the engine according to a first model and based on the at least one of the position of the throttle and the engine load. A second pressure prediction module, when one or more of the cylinders is deactivated, predicts second intake port pressures for the deactivated cylinders according to a second model and based on the status signal and the at least one of the position of the throttle and the engine load.

  • Patent number: 9181892
    Abstract: Methods and systems are provided for reducing late burn induced cylinder pre-ignition events. Forced entry of residuals from a late burning cylinder into a neighboring cylinder may be detected based on engine block vibrations sensed in a window during an open exhaust valve of the late burning cylinder. In response to the entry of residuals, a pre-ignition mitigating action, such as fuel enrichment or deactivation, is performed in the neighboring cylinder.

  • Patent number: 9157816
    Abstract: A torque sensing device includes a rotating component configured to rotate about an axis of rotation and a first sensor positioned adjacent to the rotating component to sense instantaneous angular position of the rotating component at a first location. A second sensor is positioned adjacent to the rotating component radially inboard of the first sensor to sense instantaneous angular position of the rotating component at a second location. A controller is operably coupled to the first sensor and the second sensor. The controller determines a relative phase shift between a first signal generated by the first sensor and a second signal generated by the second sensor to calculate an output proportional to a torque applied to the rotating component.

  • Patent number: 9121362
    Abstract: A system for a vehicle includes a knock indication module, a valve control module, and a fault indication module. The knock indication module selectively indicates that knock occurred within a cylinder of an engine. The valve control module controls lifting of a valve of a cylinder of the engine and, in response to the knock indication module indicating that knock occurred within the cylinder, transitions lifting of the valve from one of a low lift state and a high lift state to the other one of the low lift state and the high lift state. The fault indication module selectively indicates that a fault is present in a variable valve lift (VVL) mechanism of the cylinder based on whether the knock indication module indicates that knock occurred within the cylinder after the transition to the other one of the low lift state and the high lift state.

  • Patent number: 9115644
    Abstract: A turbocharger system for an air-throttled engine includes a variable flow expander (VFE) in the intake air conduit system that supplies intake air to the engine. At part-load operation, the VFE expands the air by an amount that is controllable, and thus regulates the air flow as needed by the engine. The power extracted by the VFE from the intake air flow is fed to the turbocharger, which helps to achieve quicker turbocharger response and improve scavenging of exhaust gases from the engine. The VFE can be a variable expansion ratio turbine.
