Abstract: A data analyzer for analyzing characterization data to form fuel injection control, including a data obtainer that obtains data from a detection signal of a sensor as a time-series data that changes over time. The data analyzer further includes a differentiator that differentiates the time-series data obtained by the data obtainer, a moving averager that calculates a moving average of the differentiated time-series data by the differentiator, an identifier that identifies a waveform of the time-series data based on the moving average calculated by the moving averager, and a data characterizer characterizes the time-series data based on the waveform of the time-series data identified by the identifier. As such, noise is removed as much as possible, and characteristics of time-series data become analyzable.

Abstract: In the start mode of a fuel supply apparatus, a subtraction value of an electric power is obtained in view of an SCV characteristic. Furthermore, a common correction value is employed as the subtraction value in order to increase an actual fuel discharge amount when the internal combustion engine is started, whereby a fuel pressure in an accumulator agrees with the target value even if an individual pump unit shows a lowest limit in the variations of the discharge amount. The common correction value is shared among the individual pump units. Even if a starting characteristic is not acquired for each of the individual supply pumps, the internal combustion engine can reliably be started.

Abstract: Highly-accurate approximate positional information is transmitted to a communication terminal. An approximate positional information database of a server included in a positioning support system includes approximate positional information used for positioning calculation at the communication terminal and which indicates a position of a cell in which the communication terminal is located and a cell identifier identifying the cell, with approximate positional information and the cell being associated with each other. Based on a positioning information transmission request which includes a cell and which is transmitted from the communication terminal, approximate positional information stored in the approximate positional information database is acquired and transmitted from a communication unit to the communication terminal.

Abstract: When a learning condition is satisfied, an operational state of an engine is adjusted in a retarded combustion operation to a misfire inducing state, at which misfire is prone to occur in a cylinder of the engine due to shortage of a pilot flame generative injection quantity. When the misfire is sensed, the pilot flame generative injection quantity of the misfired cylinder is progressively increased. Then, when the misfire is eliminated through this, a pilot flame generative correction quantity at the time of eliminating the misfire is stored. Thereafter, the pilot flame generative injection quantity is corrected based on the stored pilot flame generative correction quantity.

Abstract: A control unit for controlling fuel pressure in a common rail comprises a pressure sensor for detecting fuel pressure in the common rail, a decreased amount presuming means for calculating a presumed decreased amount (PC1) of the common rail fuel pressure, and a first determination means for comparing the detected decreased amount (PC2) of the common rail fuel pressure with the presumed decreased amount (PC1), in order to determine whether any abnormal condition is in the outputs from the pressure sensor. Therefore, the malfunction of the pressure sensor or any abnormal conditions included in the outputs from the pressure sensor can be detected even during the engine operation.

Abstract: An engine control device for controlling an exhaust gas recirculation operation includes a variable-capacity turbo supercharger, an EGR valve, a supercharging pressure controller, an EGR controller, and an EGR correction amount calculator. The variable-capacity turbo supercharger varies a flow through an exhaust turbine to change a supercharging pressure. The EGR valve adjusts an exhaust reflow amount of gas flowing from an exhaust passage to an air intake passage. The supercharging pressure controller drives the supercharger to control the supercharging pressure. The EGR controller drives the EGR valve to control the exhaust gas recirculation operation. The EGR correction amount calculator calculates an EGR correction amount according to a change in the exhaust gas recirculation operation. The EGR controller performs a feedback control operation on the EGR valve in accordance with a deviation between an EGR control amount corrected by the EGR correction amount and a target EGR control amount.

Abstract: In an electronic throttle controller, when an intake air amount detected by an air flow meter is smaller than a stall prevention judging-purpose each cylinder intake amount, a stall prevention adding amount “large” is added to intake throttle opening degree deviation, a DC motor is driven while neglecting a feedback control operation, and an opening degree of the intake throttle is controlled to be further opened from an actual preceding control position. When an execution number of the engine stop avoiding control is larger than a predetermined number within a predetermined period, an abnormal condition of a throttle position sensor is detected, and thus, energizing operation of the DC motor is stopped. The abnormal condition malfunction of the throttle position sensor can be firmly detected while an engine stall is avoided.

Abstract: A fuel injection system for an internal combustion engine includes a fuel supply pump, a fuel pressure detector, and a control unit. The fuel supply pump supplies pressurized fuel to a fuel injection valve in the internal combustion engine. The fuel pressure detector detects the pressure of the fuel supplied. The control unit controls the amount of the fuel supplied based on a deviation between an actual fuel pressure and a target fuel pressure. The control unit includes an integral term calculator and an integral term holder. The integral term calculator adds an integral compensation quantity and a last-time integral term to calculate a this-time integral term based on an integral compensation quantity that is updated according to the deviation. The integral term holder stops the updating of the integral compensation quantity and retains the last-time integral term when a defect in the fuel supply pump is detected.
