摘要： An engine control module includes at least one high side driver connected to at least one intake camshaft actuator and at least one exhaust camshaft actuator. A plurality of low side drivers is connected to the at least one intake camshaft actuator and the at least one exhaust camshaft actuator. A sliding camshaft control module selectively actuates the at least one high side driver and the plurality of low side drivers based on a status associated with the at least one intake camshaft actuator and/or the at least one exhaust camshaft actuator.

摘要： A method of determining a sliding camshaft actuator pin position based on engine crankshaft angle includes commanding a sliding camshaft actuator to perform a valve step shift, and monitoring an actuator's pin position during the valve step shift command. At least one crank angle is measured when the actuator pin position reaches or exceeds at least one predetermined pin position threshold and at least one remedial action is performed when the actuator pin position does not correlate to the at least one measured crank angle.

摘要： A vehicle system includes a position sensor, a current supply module, and a mode indicator module. The position sensor includes: an electromagnet (EM) that generates a magnetic field proximate to one of an intake valve and an exhaust valve of an engine; and a Hall-effect sensor that generates a position signal indicating a position of the one of the intake valve and the exhaust valve based on the magnetic field. The current supply module supplies current to the EM. The mode indicator module indicates whether the one of the intake valve and the exhaust valve is being actuated in a low lift mode or a high lift mode based on the position signal.

摘要： A method for heating a sliding camshaft actuator at cold engine start wherein the sliding camshaft actuator includes at least one magnetic field generating coil having a core, a piston armature disposed in the core of the at least one magnetic field generating coil, a magnet in mechanical communication with the piston armature, and an actuator pin in mechanical communication with the magnet. The method includes detecting a cold engine start condition and reversing an energizing voltage on the at least one magnetic field generating coil when the outside temperature is below a predetermined temperature threshold. The reverse energizing voltage on the at least one magnetic field generating coil is maintained for a predetermined period of time to heat the piston armature, the magnet, and the actuator pin.

摘要： A system according to the principles of the present disclosure includes a switching period module and at least one of a valve lift control module and a start-stop control module. The switching period module determines a switching period that elapses as a valve lift actuator of an engine switches between a first valve lift position and a second valve lift position that is different than the first lift position. The switching period begins when a measured position of the valve lift actuator corresponds to the first lift position and the switching period ends when the measured position of the valve lift actuator corresponds to the second lift position. The valve lift control module controls the valve lift actuator based on the switching period. The start-stop control module determines whether to automatically stop the engine based on the switching period.

摘要： A method of start/stop engine control based on vehicle location and driving situation includes identifying the location and driving situation of a host vehicle, and classifying the location and the driving situation of the host vehicle based on the identified location and driving situation. The engine start/stop control is based on at least one of the location classification and driving situation classification.

摘要： A method of noise filtering a sliding camshaft actuator pin position output signal includes determining an actual pin position output signal period of a sliding camshaft actuator that occurs within a predetermined output signal period measurement window and establishing a pin position output signal filter window based on the actual pin position output signal period. Thereafter, the actual pin position output signal period from the sliding camshaft actuator is monitored by a control module and signals that occur outside of the pin position output signal filter window are rejected accordingly to prevent responding to false triggers.

摘要： A system according to the present disclosure includes a spectral density module and a firing sequence module. The spectral density module determines a spectral density of engine speed. The firing sequence module selects a first set of M cylinders of an engine to activate, selects a second set of N cylinders of the engine to deactivate, and selects a firing sequence to activate the first set of M cylinders and to deactivate the second set of N cylinders. M and N are integers greater than or equal to one. The firing sequence specifies whether each cylinder of the engine is active or deactivated. Based on the spectral density, the firing sequence module adjusts the firing sequence to adjust M and N and/or to adjust which cylinders of the engine are included in the first set and which cylinders of the engine are included in the second set.
