  • Patent number: 10287994
    Abstract: A vehicle throttle control system includes a torque control system providing a desired torque for a throttle valve. A conversion module converts the desired torque to a desired throttle area and converts the desired throttle area to a target throttle position. A selection module determines which one of multiple MPC controllers should be used based on a current position of the throttle valve. A prediction module determines future state values using a mathematical model of a throttle body. A cost module determines a first cost for a first set of MPC target throttle duty cycle values. A control module identifies optimal sets of target throttle motor duty cycle values for each of the MPC controllers. The multiple MPC controllers control operation of a throttle valve duty cycle to achieve a target throttle opening area based on a first one of the target throttle motor duty cycle values.

  • Patent number: 10273900
    Abstract: A method to determine reference actuator positions for a gasoline engine, includes entering a base torque request, a known spark advance, a known CAM position and a known exhaust gas recirculation (EGR) valve position into an inverse torque model to generate a first iteration desired air per cylinder (APC) value. The first iteration desired APC value is passed through a deadband filter to produce a filtered first iteration desired APC signal. A Predicted As Cal (PAC) spark advance is calculated for the filtered first iteration desired APC value. The PAC spark advance and the base torque request are modified, and data from a first lookup table is entered to generate a second iteration desired APC value.

  • Patent number: 10253704
    Abstract: A method of controlling the operation of an air charging system is disclosed. A plurality of output parameters of the air charging system are monitored. An error between each one of the monitored output parameters and a target value thereof is calculated. Each one of the calculated errors is applied to a linear controller that yields a virtual input which is used to calculate a plurality of input parameters for the air charging system. Each one of the input parameters is used to determine the position of a corresponding actuator of the air charging system and operate of the actuators according to the determined position thereof. The inputs parameters are calculated with a non-linear mathematical model of the air charging system configured such that each one of the virtual inputs is in a linear relation with only one of the output parameters.

  • Patent number: 10161775
    Abstract: A method can be used for determining fuel consumption of an internal combustion engine of a vehicle, in real time. The method includes determining a fuel injection quantity of the internal combustion engine based on an oxygen concentration signal from an oxygen sensor and a MAF signal from a mass airflow (MAF) sensor. The MAF sensor is coupled to the intake line and is configured to measure and monitor the mass flow rate of intake air flowing through the intake line. The method further includes determining, via an engine control module (ECM), an instantaneous fuel flow of the internal combustion engine based on the fuel injection quantity. The method further includes communicating, via the ECM, the instantaneous fuel flow to a body control module (BCM) and determining, via the BCM, an average fuel economy of the internal combustion engine based on the fuel flow.

  • Patent number: 10138860
    Abstract: A variety of methods and arrangements are described for controlling transitions between effective firing fractions during dynamic firing level modulation operation of an engine in order to help reduce undesirable NVH consequences and otherwise smooth the transitions. In general, both feed forward and feedback control are utilized in the determination of the effective firing fractions during transitions such that the resulting changes in the effective firing fraction better track cylinder air charge changing dynamics associated with the transition.

    Abstract: A propulsion system, control system, and method are provided that use model predictive control to generate an initial selected engine output torque value. A minimum torque limit is determined by selecting a minimum acceptable engine output torque. A maximum torque limit is determined by selecting a maximum acceptable engine output torque. A desired engine output torque value is set as: a) the minimum torque limit, if the initial selected engine output torque value is less than the minimum torque limit; b) the maximum torque limit, if the initial selected engine output torque value is greater than the maximum torque limit; or c) the initial selected engine output torque value, if the initial selected engine output torque value is neither greater than the maximum torque limit nor less than the minimum torque limit.
