  • Patent number: 10788396
    Abstract: A calibration system and method for a spark ignition engine of a vehicle involve artificially weighting engine dynamometer data in high engine load regions and using it to generate training data for an artificial neutral network (ANN). A plurality of ANNs are trained using the training data and the plurality of ANNs are then filtered based on their maximum error to obtain a filtered set of trained ANNs. A statistical analysis is performed on each of the filtered set of trained ANNs including determining a set of statistical metrics for each of the filtered set of trained ANNs and then one of the filtered set of trained ANNs having a best combination of error at high engine loads and the set of statistical error metrics is then selected. Finally, an ANN calibration is generated using the selected one of the filtered set of trained ANNs.

  • Patent number: 10760532
    Abstract: Methods and systems are provided for conducting an ejector system diagnostic under conditions where an engine of a vehicle is not combusting air and fuel. In one example, a method comprises directing a positive pressure to the ejector system while the engine is off in order to communicate a negative pressure with respect to atmospheric pressure on a fuel system and an evaporative emissions system of the vehicle, and indicating that the ejector system is degraded responsive to the negative pressure not reaching a vacuum build threshold. In this way, the ejector system may be diagnosed under conditions where boosted engine operation is infrequent and/or of durations insufficient for conducting such an ejector system diagnostic.

    Abstract: A fuel injection control device includes a conduction time calculation unit, a detection unit, an estimation unit, a correction unit, a sudden change determination unit, and a reflection speed setting unit. The detection unit detects a physical quantity having a correlation with an actual injection quantity during the partial lift injection. The estimation unit estimates the actual injection quantity on the basis of a detection result of the detection unit. The correction unit corrects the requested injection quantity by a correction quantity corresponding to a deviation between the actual injection quantity and the requested injection quantity. The sudden change determination unit determines whether or not the correction quantity is in a sudden change state on the basis of whether or not the correction quantity has changed from a previous value by a prescribed quantity or more. The reflection speed setting unit sets the reflection speed.

  • Patent number: 10711722
    Abstract: A controller includes a P/L learning unit that performs P/L learning, a purge learning unit that performs purge learning, an air-fuel ratio learning unit that performs air-fuel ratio learning, and a storage unit that stores learning result. When the learning result of each learning process is not stored in the storage unit at the time of engine start, the P/L learning unit learns an injection characteristic of an in-cylinder injection valve through the P/L learning process whenever the in-cylinder injection valve performs the P/L injection and interrupts the P/L learning process before the P/L learning process is completed. The purge learning unit performs the purge learning process, and the air-fuel ratio learning unit starts the air-fuel ratio learning process provided that the P/L learning process is interrupted. The P/L learning unit then resumes the P/L learning process provided that the purge learning process is completed.
