摘要： A control system for controlling operation of an internal combustion engine is configured to: receive a first request signal indicative of first torque demand; determine a schedule defining an opening timing of the intake valve and a closing timing of the intake valve of a cylinder of the internal combustion engine in dependence on the first torque demand; and cause the intake valve to open in accordance with the schedule. The control system is also configured to, during a period in which the intake valve is open: receive a second torque request signal indicative of a second torque demand different to the first torque demand; determine an updated schedule defining an updated closing timing of the intake valve in dependence on the second torque demand; and cause the intake valve to close in accordance with the updated schedule.

摘要： A method for controlling a vehicle power train that includes a heat engine connected to the transmission of the vehicle by a clutch controlled between an open position and a closed position of the transmission by a computer of the transmission exchanging information with a computer of the heat engine. The method includes sending, in order to shut down the engine before the clutch is opened when the vehicle is in motion, the kinematic chain being closed and the injection interrupted, a message from the computer of the transmission to the computer of the engine at a first moment in time so as to synchronize an opening of the clutch and the closure of an air flap of the engine at a second moment in time subsequent to the first moment.

摘要： Diagnosis system, method, and apparatus for a starting system are discloses herein. The method comprises receiving a run condition parameter for a vehicle, receiving a fueling system engagement parameter and an associated time threshold for the fueling system engagement parameter, and receiving an ignition command for turning an engine of the vehicle from an off state to an on state. If the run condition parameter is met, the method receives time data indicative of a time duration from reception of the ignition command to reach or substantially reach the fueling system engagement parameter, compare the time duration to the associated time threshold, and diagnose a starting system of the vehicle based on the comparison.

摘要： A computer-implemented method for calculation and output of control pulses by a control unit having a first computing unit and a second computing unit, wherein the control pulses are output by the control unit to an internal combustion engine. The calculation of the control pulses is optimized in that the first computing unit calculates a control pulse pattern with triggering information for multiple future control pulses at a first sampling rate using prior state data of the engine, and transmits the calculated control pulse pattern to the second computing unit, that the second computing unit at a second sampling rate that is greater than the first sampling rate of the first computing unit corrects the triggering information of the control pulses that are currently to be output using current state data of the engine, and that control pulses are output to the engine based on the corrected triggering information.

摘要： The timing of a controlled event is advanced or retarded in an IC engine by emulating the engine speed and position signal pattern prior to transmission of that signal pattern to an output such as a fuel injector. In a multi-controller engine in which a second controller is controlled at least in part by signals delivered by first controller, the signal preferably is emulated in the first controller prior to transmission to the second engine controller in order to allow the shifting of a timing of a controlled event without direct data transfer from the second controller to the first controller. The technique is particularly well-suited for controlling diesel fuel injection in a dual fuel or other multi-fuel engine. In this case, the first controller must be a dual fuel controller and the second controller may be a diesel controller.

摘要： A fuel injection control device includes a throttle opening read timing setter that sets the timing at which a throttle opening is read. The setter is triggered to detect the throttle opening used for calculation of a basic injection amount by the start of calculation timing of the basic injection amount (FICAL) if the FICAL is at the position corresponding to a toothless part of a crank pulsar rotor. The setter detects the throttle opening based on crank pulse interrupt according to a crank pulse if the FICAL is at a position other than the position corresponding to the toothless part.
