  • Patent number: 11053880
    Abstract: A storage device of a control system stores a trained neural network that is trained by using training data to which information as to whether there is an abnormality in an air flow meter is given as a true label. The trained neural network receives, as inputs, condition index values including the opening of a throttle valve and the engine speed, a load detected value calculated based on a detection signal of the air flow meter, a load estimated value estimated without using the detection signal of the air flow meter, and a change index value indicating the degree of change of the engine load. A CPU of the control system executes a diagnostic process to determine whether there is an abnormality in the air flow meter, using the neural network, which receives the condition index values, load detected value, load estimated value, and change index value as the inputs.

  • Patent number: 10968841
    Abstract: Skip fire engine control using a first order sigma delta based firing controller is described. An engine controller determines a skip fire firing fraction and (as appropriate) associated engine settings that are suitable for delivering a requested output. The operational firing fraction is selected from a set of available firing fractions. The engine controller uses a first order sigma delta based converter to direct working cycle firings in a skip fire manner that delivers the selected firing fraction. The converter includes or functions substantially equivalent to a first order sigma delta converter and may be implemented any of: algorithmically using a processor; using digital, analog or hybrid components; using a lookup table; or using other appropriate techniques. In some embodiments firing decisions are made on a working cycle by working cycle basis. The described approach may be used in gasoline engines, diesel engines, turbocharged or supercharged engines, or others.
