System And Method For Mode Transition For A Two-Stage Series Sequential Turbocharger
view source
US Patent:

8096123, Jan 17, 2012
Filed:

May 29, 2009
Appl. No.:

12/474599
Inventors:

Zhiping Liu - Canton MI, US
Ping Ge - Northville Township MI, US
Anupam Gangopadhyay - Chennai, IN
International Classification:

F02B 33/44
US Classification:

606051, 60599, 60602
Abstract:

A method of controlling a series turbocharger for an engine and a control system for the same includes a boost determination module determining a first predicted boost pressure for a first position of a variable geometry turbine when a high pressure turbine bypass valve is in an open position. The boost determination module determines a second boost pressure for a second position of the variable geometry when the high pressure turbine bypass valve is in the open position. A desired boost module determines a desired boost. A comparison module determines when the desired boost signal is between the first predicted boost pressure and the second predicted boost pressure. A bypass valve control module closes the high pressure turbine bypass valve when the desired boost signal is between the first predicted boost pressure and the second predicted boost pressure.

123490, 123491
Abstract:

An engine control system comprises a current control module and a solenoid actuator module. The current control module determines a duty cycle based on a desired current through a solenoid of an engine system and a resistance of the solenoid and corrects the resistance based on an actual current through the solenoid. The solenoid actuator module actuates the solenoid based on the duty cycle.

The system also includes a high pressure turbine bypass valve control module operating a high pressure turbine bypass valve in a closed position in a first load-engine speed region. The variable nozzle turbine control module operates a variable nozzle turbine closed loop in a second load-engine speed region between the first load-speed region and a third load speed region. The high pressure turbine bypass valve module operates the high pressure turbine bypass valve in a transient region in the second load-engine speed region. The variable nozzle turbine control module operates the variable nozzle turbine open loop.

US Patent:

8302397, Nov 6, 2012
Filed:

Aug 11, 2009
Appl. No.:

12/539357
Inventors:

Zhiping Steven Liu - Canton MI, US
B. Jerry Song - Novi MI, US
Anupam Gangopadhyay - MRC Nagar, IN
Ping Ge - Northville Township MI, US
International Classification:

F02D 23/00
F02B 33/44
F02B 33/00
US Classification:

60602, 60612, 123562
Abstract:

A system for a sequential turbocharger includes a mode selection module, a feed-forward selection module, and a control loop module. The mode selection module generates a control mode signal based on an engine speed signal, an engine torque signal, and an engine mode signal. The control mode signal indicates one of an open-loop control mode and a closed-loop control mode. The feed-forward selection module determines a feed-forward value based on the control mode signal, the engine speed signal, and the engine torque signal. The control loop module determines a loop control value at least one of based on the feed-forward value, a variable geometry turbine (VGT) control signal, and an error signal; and based on a bypass valve (BPV) control signal and the error signal when the control mode signal transitions from the open-loop control mode to the closed-loop control mode.

US Patent:

8640459, Feb 4, 2014
Filed:

Oct 23, 2009
Appl. No.:

12/604762
Inventors:

Ping Ge - Northville Township MI, US
Donald R. Meyer - Canton MI, US
International Classification:

F02B 33/44
F02D 23/00
F02B 33/00
US Classification:

60612, 60602, 123562
Abstract:

A turbocharger control system for a high-pressure turbocharger and a low-pressure turbocharger includes a turbo mode determination module and a transition control module. The turbo mode determination module determines a transition from a dual turbo mode to a single turbo mode. The high-pressure turbocharger is active in the dual turbo mode and idle in the single turbo mode. The transition control module determines a turbine efficiency of the high-pressure turbocharger and controls the high-pressure turbocharger during the transition based on a predetermined maximum turbine efficiency equation.

US Patent:

20120023932, Feb 2, 2012
Filed:

Jul 28, 2010
Appl. No.:

12/844869
Inventors:

Ping Ge - Northville MI, US
Assignee:

GM GLOBAL TECHNOLOGY OPERATIONS, INC. - Detroit MI
International Classification:

F02D 23/00
US Classification:

60602
Abstract:

A vehicle includes an engine, an air intake assembly having a variable geometry turbine (VGT) controllable using a turbine mass flow map, an exhaust manifold, and a controller. The controller calculates a pressure ratio between the inlet and outlet sides of the VGT, and first and second exhaust manifold pressures using respective first and second models. Each of the models extracts information from the map. The controller executes a control action using the first pressure when the ratio exceeds a threshold, using the second pressure otherwise. The controller itself is also disclosed herein, as is a method for controlling an engine operation aboard the vehicle. The method includes using the host machine to calculate the exhaust pressure ratio, to calculate the first and second pressures using the respective first and second models, and to execute a control action using the first or second exhaust pressure depending on the ratio.
