  • Publication number: 20190271278
    Abstract: Methods and systems are provided for learning fuel injector error for cylinder groups during a deceleration fuel shut-off (DFSO), where all cylinders of an engine are deactivated, sequentially firing each cylinder of a cylinder group, each cylinder fueled via consecutive first and second fuel pulses of differing fuel pulse width from an injector. Based on a lambda deviation between the first and second pulses, a fuel error for the injector and an air-fuel ratio imbalance for each cylinder is learned. Alternatively or additionally, a difference in crankshaft acceleration between the first and second pulses relative to the expected deviation may be used to learn torque error, and adjust fuel injector error and air-ratio imbalance for each cylinder.

  • Publication number: 20190262201
    Abstract: A patient support apparatus may include a support surface configured to conduct air along a top face of the support surface so that heat and moisture from a patient lying on the support surface are drawn away from the top face of the support surface. An opening may be formed in a side of the support surface. A cavity may extend from the opening into the support surface. An inlet port may be positioned within the cavity and fluidly coupled to the top face. A blower assembly may be configured to position within the cavity. The blower assembly may have an outlet port that couples to the inlet port when the blower assembly is positioned within the cavity. The blower assembly may conduct air through the inlet port to the top face of the support surface.

  • Patent number: 10337423
    Abstract: Methods and systems are provided for adjusting engine operation based on estimated vaporized and condensed portions of water injected during a water injection event. In one example, a method may include injecting an amount of water into the intake manifold in response to engine conditions and inferring vaporized and condensed portions of the injected water based on the injected amount and a change in manifold temperature following the injection. Further, the method may include adjusting water injection and engine operating parameters in response the evaporated and/or condensed portion of water.

  • Patent number: 10184429
    Abstract: Methods and systems are provided for selecting a location for water injection during a water injection event based on engine operating conditions. In one example, a method may include selecting a location for water injection from each of an intake port of each cylinder, an intake manifold upstream of all engine cylinders, and directly into each cylinder based on engine operating conditions. Further, the method may include adjusting water injection at the selected location and engine operating parameters in response the evaporated and/or condensed portion of water.

  • Patent number: 10066571
    Abstract: Methods and systems are provided for leveraging the charge cooling effect of a manifold fuel injection. A charge cooling effect of a scheduled manifold fuel injection may be predicted based on feedback received from a manifold charge temperature sensor during a preceding manifold injection event. If sufficient charge cooling is not predicted, the manifold fuel injection is temporarily disabled.

  • Publication number: 20180121763
    Abstract: Method, apparatus and computer readable media are disclosed for object classification adjustment based on vehicle communication. An example vehicle includes a camera to detect an object and an object classifier. The example object classifier is to determine first classification data for the object. The first classification data includes a classification confidence of the object. Also, the example object classifier is to associate second classification data for the object with the first classification data. The second classification data is collected from a second vehicle. Additionally, the example object classifier is to adjust the classification confidence of the object based on the second classification data.

  • Patent number: 9957906
    Abstract: Methods and systems are provided for estimating a positive crankcase ventilation (PCV) flow based on outputs of an intake manifold oxygen sensor. For example, during engine operation when exhaust gas recirculation (EGR) and fuel canister purge are disabled, PCV flow may be estimated based on a difference between a first output of the sensor with boost enabled and a second output of the sensor with boost disabled. Then, during subsequent operation wherein EGR is enabled, PCV flow is enabled, and purge is disabled, a third output of the sensor may be adjusted based on the estimated PCV flow.

  • Patent number: 9926871
    Abstract: A method for an engine may comprise, responsive to a first condition comprising a reference voltage of a first exhaust oxygen sensor operating in variable voltage mode increasing above a threshold voltage, determining a change in an output of the first exhaust oxygen sensor corresponding to the increase in the reference voltage, correcting the output of the first oxygen sensor based on the output change, and adjusting engine operation based on the corrected output. In this way, the accuracy of air-fuel estimates based on the exhaust gas sensor can be preserved, and closed loop fuel control of the engine can be maintained even when the exhaust oxygen sensor is operating VVS mode, thereby reducing engine emissions, increasing fuel economy, and increasing vehicle drivability.

  • Patent number: 9897027
    Abstract: Methods and systems are provided for estimating an impact of PCV hydrocarbons on an output of an intake oxygen sensor. In one example, a method may include disabling EGR flow when the impact of PCV hydrocarbons on the output of the intake oxygen sensor is above a threshold. The impact of the PCV hydrocarbons on the output of the intake oxygen sensor may be based on a difference between the output of the intake oxygen sensor and a DPOV sensor when EGR is flow and a difference between the output of the intake oxygen sensor and expected blow-by when EGR is not flowing.
