摘要:
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.

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.

A method of controlling a turbocharger for an engine and a control system for the same includes a variable nozzle turbine control module operating a variable nozzle turbine of a high pressure turbocharger closed loop in a first load-engine speed region. 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. The high pressure turbine bypass valve control module operates a high pressure turbine bypass valve in an open position in a third load-engine speed region.

摘要:
An electronic device with a message encryption function that includes a message processing module for receiving or sending or reading encrypted messages. The message processing module is electrically connected to a configure interface module, a storage module and an encryption module. The message processing module checks whether an encryption code exists. Then the message processing module checks whether the message processing event is “reading a message”. If the processing module determines the processing event is “reading a message” the processing module determines whether the encrypted message has been read or not. If the encrypted message has been read the processing module directly transmits the encrypted message back and then displays the encrypted message. If the encrypted message has not been read the processing module decrypts the encrypted message to generate a decrypted message and transmits the decrypted message back and then displays the decrypted message in a clear-text manner.
