Patent number: 10371018Abstract: A method, control system, and variable valve timing system are provided for controlling an actuator that can be switched into an on state and an off state with pulse width modulation. The systems and method include controls configured to determine an actual system parameter on a first time schedule and a desired system parameter on a second time schedule. On a third time schedule, a position error difference between the actual system parameter and the desired system parameter is determined. The third time schedule is configured to begin and to determine the position error difference each time that the actual system parameter is determined and each time that the desired system parameter is determined. A desired duty cycle is determined, and a duty cycle command is sent to a pulse width modulation output unit.Type: GrantFiled: March 24, 2017Date of Patent: August 6, 2019Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Klaus Pochner, Uwe Steinmann, Kea Hyuk Chang, Scott T Feldmann, Jon C Wasberg

Patent number: 9353694Abstract: An engine control system of a vehicle includes a first temperature module, a second temperature module, and an exhaust gas recirculation (EGR) control module. The first temperature module determines a temperature of gas within an intake manifold of an engine. The second temperature module determines a temperature of an EGR conduit that is coupled to the intake manifold. The EGR control module reduces opening of an EGR valve when the temperature of the gas and the temperature of the conduit is greater than a predetermined temperature.Type: GrantFiled: June 17, 2013Date of Patent: May 31, 2016Assignee: GM Global Technology Operations LLCInventors: B. Jerry Song, Gregory J. York, Jon C. Wasberg, Josef J. Correia, Timothy Ward Athan

Publication number: 20130268176Abstract: A partial pressure determination module: determines a first partial pressure of oxygen in an intake manifold of an engine based on an output of a first oxygen sensor measuring oxygen in the intake manifold; and determines a second partial pressure of oxygen in an exhaust system based on an output of a second oxygen sensor measuring oxygen in the exhaust system. A concentration determination module: determines a concentration of oxygen in the intake manifold based on the first partial pressure and an intake manifold; and determines a concentration of oxygen in the exhaust system based on the second partial pressure. A flowrate determination module determines a mass flowrate of exhaust gas recirculation (EGR) based on the concentration of oxygen in the intake manifold and the concentration of oxygen in the exhaust system. An actuator control module controls an engine operating parameter based on the mass flowrate of EGR.Type: ApplicationFiled: April 5, 2012Publication date: October 10, 2013Applicant: GM Global Technology Operations LLCInventors: B.

Publication number: 20130226435Abstract: A system according to the principles of the present disclosure includes a volumetric efficiency adjustment module and an exhaust gas recirculation (EGR) flow adjustment module. The volumetric efficiency adjustment module adjusts an estimated volumetric efficiency of an engine based on a mass flow rate of air entering the engine. The EGR flow adjustment module selectively adjusts an estimated mass flow rate of exhaust gas passing through an EGR valve based on an amount by which the volumetric efficiency adjustment module adjusts the volumetric efficiency.Type: ApplicationFiled: February 29, 2012Publication date: August 29, 2013Applicant: GM Global Technology Operations LLCInventors: Jon C.

Patent number: 8483935Abstract: A method for selectively creating vacuum in a hybrid powertrain controlled by a hybrid control processor and having an engine controlled by an engine control module includes requesting a pressure differential between a first intake point and a second intake point, wherein the first intake point and the second intake point are separated by a throttle. An actual torque capacity is calculated for the engine, wherein the actual torque capacity occurs when pressure is substantially equal at the first intake point and at the second intake point. A desired torque capacity is also calculated for the engine, wherein the desired torque capacity reduces the pressure at the second intake point relative to the pressure at the first intake point, such that the requested pressure differential is created. The engine is then operated at one of the desired torque capacity and the actual torque capacity.Type: GrantFiled: September 9, 2010Date of Patent: July 9, 2013Assignee: GM Global Technology Operations LLCInventors: Christopher E. Whitney, William R. Cawthorne, Anthony H. Heap, Jeffrey M. Kaiser, Dennis A. Light, Jon C. Wasberg, Weixin Yan

Patent number: 7748362Abstract: An engine control system includes an air control module, a spark control module, a torque control module, a transient detection module, and a launch torque module. The air control module controls a throttle valve of an engine based on a commanded predicted torque. The spark control module controls spark advance of the engine based on a commanded immediate torque. The torque control module increases the commanded predicted torque when a catalyst light-off (CLO) mode is active, and increases the commanded immediate torque when a driver actuates an accelerator input. The transient detection module generates a lean transient signal when an air per cylinder increase is detected while the CLO mode is active. The launch torque module generates a torque offset signal based on the lean transient signal. The torque control module increases the commanded immediate torque based on the torque offset signal.Type: GrantFiled: May 7, 2009Date of Patent: July 6, 2010Inventors: Christopher E. Whitney, Michael S. Emmorey, Jeffrey M. Kaiser, Robert C. Simon, Jr., Cheryl A. Williams, Jon C. Wasberg, Eric Ferch, Craig M. Sawdon
