  • Publication number: 20220281432
    Abstract: The present disclosure provides a hybrid powertrain system, comprising: an engine; a motor/generator (“MG”); a clutch coupled to the engine and the MG; a transmission coupled to the MG; an energy storage system connected to the MG; and a controller coupled to the engine, the MG, the clutch, the transmission and the energy storage system. The controller is configured to initiate an engine stop, allow engine torque and MG torque to reduce to zero or near zero, shift the transmission to a neutral gear, cause the MG to operate in a generator mode, thereby loading the engine to recover kinetic energy from the engine, disengage the clutch to decouple the MG from the engine, increase the speed of the MG to a target speed, and shift the transmission into gear in response to the MG reaching the target speed.

  • Patent number: 11378026
    Abstract: A spark ignited internal combustion engine is controlled in response to a self-learned TOB reference. The self-learned TOB reference is based on a difference between a learned TOB offset and a desired or target TOB, and a sensed TOB. The learned TOB offset at a given operating condition, such as charge pressure, can be found by interpolating between the learned charge pressure breakpoints in a TOB learning algorithm. The TOB learning algorithm can include using a filtered charge pressure value to indicate the engine load at which the TOB is learned. An index determination is made with a look up table with charge pressure as an input and an array index of learned charge pressure and learned TOB offset as outputs.

  • Patent number: 11053881
    Abstract: A system for control of an internal combustion system having subsystems, each with different response times. Subsystems may include a fuel system, an air handling system, and an aftertreatment system, each being operated in response to a set of reference values generated by a respective target determiner. Calibration of each subsystem may be performed independently. The fuel system is controlled at a first time constant. The air handling system is controlled on the order of a second time constant slower than the first time constant. The aftertreatment system is controlled on the order of a third time constant slower than the second time constant. A subsystem manager is optionally in operative communication with each target determiner to coordinate control. Generally, dynamic parameters from slower subsystems are treated as static parameters when determining reference values for controlling a faster subsystem.

  • Patent number: 11047358
    Abstract: A system for harmonizing knock in a plurality of cylinders included in an engine, the system comprises a plurality of knock sensors, and a controller coupled to each of the plurality of knock sensors. The controller is configured to receive a plurality of cylinder knock values corresponding to each of the plurality of knock sensors, and receive an average knock value. The controller determines a cylinder spark timing offset value for each cylinder in the plurality of cylinders from the average knock value and the cylinder knock values. The controller determines an average spark timing offset value. The controller also determines an adjusted spark timing value for each of the plurality of cylinders by subtracting the average spark timing offset value from a spark timing value of each of the plurality of cylinders.

  • Patent number: 11035310
    Abstract: Methods and apparatuses for calibration and control of various engine subsystems using a target value approach. Under the target value approach, the control of each engine subsystem is separated or decoupled to include a set of target values, or a reference value set. A subsystem has a corresponding target determiner, which provides a target value set, or reference value set, in response to a basis variable set and optionally an overall subsystem target. The basis variable set includes parameters selected to robustly characterize the variables that affect the operation of the particular subsystem. The target determiner is optionally calibrated to provide a reference value set within specifications of the subsystem. A physical subsystem controller operates in response to the reference value set.
