摘要： An ECU detects heat generation center of gross heat value. A combustion state of an engine is determined based on the heat generation center. When a deviation between the average heat generation center and the subject heat generation center exceeds a predetermined value, the ECU determines that the engine combustion state is deteriorated. With respect to a cylinder in which the combustion state is deteriorated, fuel injection amount is increased. With respect to a cylinder in which the combustion state is not deteriorated, the fuel injection amount is decreased in order to perform lean-limit control.

摘要： At time of starting an engine, stop/rotation of an electric motor is sensed based on presence/absence of output pulses of an encoder installed in the motor. Controlling of power supply to the motor is prohibited to maintain an off-state of the motor until start of rotation of the motor is sensed. When the start of the motor is sensed, the controlling of the power supply to the motor is started. At time of stopping the engine, stop/rotation of the motor is sensed based on time intervals of pulses outputted from the encoder. The controlling of the power supply to the motor is enabled until sensing of stopping of rotation of the motor. When the stopping of rotation of the motor is sensed, the controlling of the power supply to the motor is prohibited to stop the power supply to the motor.

摘要： A motor current (driving current of motor) is estimated based on a target motor speed, an actual motor speed, and an engine speed. When the estimated motor current exceeds the upper limit value equivalent to a heat generation limiting current, the motor current is restricted by restricting a variation (motor speed F/B amount) in target motor speed outputted to an EDU from an ECU. If it is continued that a deviation between the target motor speed and the actual motor speed exceeds a predetermined value, the estimated motor current exceeds this upper limit value and the restricting action of the motor current is continued.

摘要： A waveform knock signal detected by a knock sensor is filtered through a band-pass filter. The detected wave form signal is compared with an ideal reference knock waveform to determine an engine knock. The ideal reference knock waveform is derived on the basis of a factor depending on a crank angle, a factor depending on a real time and a factor depending on an engine construction. The factor depending on the real time is calculated based on an energy loss in a combustion chamber and a time constant of the band-pass filter. The factor depending on the engine construction is calculated based on a knock vibration which is generated in a cylinder, transferred to a cylinder block and detected by the knock sensor.

摘要： A variable valve timing adjuster with an intermediate lock mechanism learns a lock position and a lock release control. During a lock control, a learning of the lock position from a real camshaft phase is repeated to update the learned value, and the learning is ended when it is judged that the learned values have converged. At this time, when the learned values of the lock position do not converge even if the number of learning of the lock position exceeds a predetermined value, an insufficient lock state is judged, and the learned value of the lock position is set to an initial value or the learned value at the previous lock control thereby to make a lock release control. During the lock release control, on the other hand, the control (or the lock release control) of a hydraulic control valve is learned. When the lock cannot be released during the lock release control, the lock release control (or the learned value) is corrected in a direction to facilitate the lock release. When the correction of the lock release control is repeated a predetermined or more number of times or when the lock release control goes outside a predetermined range, the lock release failure is judged.

摘要： A motor current is estimated based on a target motor speed, an actual motor speed, and an engine speed. When the estimated motor current exceeds a predetermined value equivalent to a heat limiting current value, a variation (motor speed F/B amount) of the target motor speed outputted to an EDU from an ECU is restricted so that the motor current was restricted and heat generation in motor is restricted. In consideration of a deterioration of responsivity of the variable valve timing control due to restriction of the motor current during execution of motor current restriction processing, an existence of the abnormalities of variable valve timing controller is determined based on a deviation of the target camshaft phase and the actual camshaft phase.

摘要： An ECU outputs a signal indicative of a target motor speed calculated based on a deviation between a target camshaft phase and an actual camshaft phase to an EDU. The EDU performs a feedback control of the output current (motor current) of the EDU so that the deviation is decreased, whereby an actual camshaft phase is feedbacked to a target camshaft phase. When the supply voltage of EDU is less than the operation limit voltage established higher than minimum operation assurance voltage, the variation of the target motor speed is restricted. Thereby, the output current of EDU is restricted, and further, when the supply voltage is less than minimum operation assurance voltage, the output current of EDU is intercepted.
