摘要:
A control system for an engine of a vehicle includes an adder module that determines a temperature sum based on a sum of a plurality of temperatures determined based on (i) a plurality of operating parameters of the vehicle and (ii) a plurality of predetermined values calibrated for determining an estimated temperature at a location within an exhaust system of the vehicle. A temperature difference module determines a temperature difference based on the temperature sum and a previous value of the temperature difference. An estimating module determines the estimated temperature at the location within the exhaust system based on the temperature difference and a reference temperature. An actuator control module selectively adjusts at least one engine actuator based on the estimated temperature.

A power generating set includes an engine operable in response to a flow of fuel to produce a flow of exhaust gas, a generator coupled to the engine and operable in response to operation of the engine to produce a total electrical power, and a primary load electrically connected to the generator to receive a portion of the total electrical power, the primary load having a cyclical pattern. A battery bank is selectively connected to the generator to receive a portion of the total electrical power and an insulated-gate bipolar transistor (IGBT) is positioned to selectively transition between a connected state and a disconnected state. The battery bank is connected to the generator to charge the battery bank when the IGBT is in the connected state and is disconnected from the generator when the IGBT is in the disconnected state.

An on-board vehicle computing system stores values in a memory of a first engine control unit (ECU) and stores corresponding backup values in a memory of a second ECU. In this way, the second ECU provides data backup functionality for the first ECU's data. The system may retrieve a backup value from the first ECU and restore the corresponding value in the second ECU using the backup value. In one illustrative scenario, if an original engine ECU (EECU) fails and a replacement EECU is installed, the system can retrieve backup values for vehicle speed limiter (VSL) parameters from memory in a cab ECU (CECU) and update the corresponding data in the replacement EECU with the backup values.

A method for controlling an electrical actuator for a wastegate valve arrangement of an exhaust gas turbocharger in an internal combustion engine is provided. A wastegate is situated in a bypass channel of the exhaust gas turbocharger. The method includes closing or opening the wastegate by the actuator for adjusting the exhaust gas flow routed past the exhaust gas turbocharger via the bypass channel. The wastegate is exposed to a predetermined closing force while it is in a closed state so as to regulate the closing force to a desired value for the closing force as a function of an actual value for the closing force. Computer-readable mediums embodying a computer program product having a program to perform the method are also provided.

A valve timing controller has the drive circuit which performs a feedback control of the energization to the electric motor based on the target rotation speed and the actual rotation speed of the electric motor, and rotates the electric motor to the target rotation direction. An invalid switch part of the drive circuit suspends the feedback control at the time of change of the target rotation direction.

Provided is a control apparatus for an internal combustion engine which controls the internal combustion engine in such a manner as to prevent excessive overshoot of an actual phase angle at a time of phase angle feedback control. The control apparatus for an internal combustion engine includes: a unit for detecting an actual phase angle of a camshaft based on a crank angle signal and a cam angle signal; a unit for setting a target phase angle of the camshaft based on an operational state; and a unit for performing phase angle feedback control calculation such that the actual phase angle coincides with the target phase angle, to calculate an amount of operation for the hydraulic pressure control solenoid valve, in which: the phase angle feedback control calculation is started for a first time after a KEY is turned ON with an initial value of an integral term set to a predetermined value; the phase angle feedback control calculation is performed using a control gain obtained by multiplying a control gain at a time of normal control when a control difference is equal to or larger than a preset value during the phase angle feedback control; and the phase angle feedback control calculation is performed using the control gain at the time of normal control when the control difference is smaller than the preset value during the phase angle feedback control.

An electropneumatic actuator system for operating assemblies of an internal combustion engine includes a housing, in which an actuator is movably accommodated, which in turn is configured to be hollow and includes an aeration channel and a deaeration channel. A control slide valve is assigned to the actuator which is operated by a magnetic coil and which aerates, deaerates or closes a pressure chamber of the housing as a function of the relative position of the actuator.
