摘要： A method of controlling intake and exhaust cam phase in an internal combustion engine includes sensing an engine speed and an engine load of the internal combustion engine, sensing or estimating a wall temperature of a cylinder of the internal combustion engine, utilizing the engine speed and the engine load in one or more lookup tables based on the cylinder wall temperature to determine intake phaser constraint values and exhaust phaser constraint values for cold operation of the internal combustion engine, and transitioning the intake phaser constraint values and the exhaust phaser constraint values for cold operation to intake phaser constraint values and exhaust phaser constraint values based on one or more lookup tables for normal hot operation of the internal combustion engine.

摘要： A control method for selecting an optimal multiple step operating mode for a multiple cylinder motor vehicle engine system having variable lift includes prioritizing each of a full torque capacity (FTC) mode having all cylinders operating at high lift, a first reduced capacity economy mode (RCE1) having all cylinders operating at low lift, and a second reduced capacity economy mode (RCE2) having fewer than all of the cylinders operating at low lift with at least one cylinder deactivated based on predicted fuel economy of each of the modes. Multiple constraints are applied to each of the prioritized modes including incorporating boost as one of the constraints by calculating a maximum torque capacity for each mode that is a function of a current boost pressure. A mode determination arbitration is conducted to identify if a change in mode is required.

摘要： A method of transitioning between two intake valve lift states while providing constant engine torque output comprehends the steps of receiving a lift change request from an engine control device, determining the current phase angles of the camshafts, and determining whether the intake and exhaust camshafts are at transition positions. The transition positions are experimentally or empirically determined combinations of operating conditions that result in constant engine torque output before and after the intake valve lift transition. If they are, an appropriate, i.e., low to high or high to low cam lift state transition of the intake valves occurs. If they are not, the cam phasers move the intake and exhaust camshafts to transition positions. When the cam phasers have moved the intake and exhaust camshafts to the transition positions, i.e., positions of constant engine torque output, the intake valve lift transitions from high to low or low to high.

摘要： A torque requesting module generates a first torque request for a spark ignition engine based on driver input. A torque conversion module converts the first torque request into a second torque request. A setpoint module generates setpoints for the spark ignition engine based on the second torque request. A model predictive control (MPC) module: identifies sets of possible target values based on the setpoints; generates predicted parameters based on a model of the spark ignition engine and the sets of possible target values, respectively; selects one of the sets of possible target values based on the predicted parameters; and sets target values based on the possible target values of the selected one of the sets. A first constraint module selectively sets a predetermined range for first one of the target values. The MPC module limits the first one of the target values to within the predetermined range.

摘要： A method of warming a catalyst of an exhaust gas treatment system of a hybrid vehicle includes transitioning a rotational speed of an engine to within a pre-defined speed range with an electric motor, and reducing an engine manifold pressure to within a pre-defined pressure range. The engine is fueled after the rotational speed of the engine is within the pre-defined speed range, and the engine manifold pressure is within the pre-defined pressure range. While the engine is being fueled, the engine manifold pressure is increased to within a catalyst light-off pressure range, and the torque output of the engine is increased to within a catalyst light-off operating torque range. The exhaust gas produced from the operation of the engine within the pre-defined speed range, within the catalyst light-off pressure range, and within the catalyst light-off operating torque range heats the catalyst while minimizing emissions.

摘要： A method of commanding a synchronous gear shift begins by receiving a request to shift from a third gear to a first gear, and skipping a second gear having a gear ratio between the gear ratio of the first gear and the gear ratio of the third gear. Subsequently the method includes: reducing a torque command to a predetermined value; opening a clutch disposed on the input shaft of the transmission to decouple the transmission from the engine; transitioning the engine from a torque-control mode into a speed-control mode; commanding the engine to rotate at a speed dictated by the motion of the vehicle and the gear ratio of the first gear; closing the clutch to couple the transmission and the engine; and transitioning the engine back into the torque-control mode.
