摘要： A device and associated method for controlling ignition timing of an internal combustion engine are provided. By comparing a determination value and knock magnitude, determination of knocking is made, and ignition timing is advanced or retarded. The device includes an operation unit that sets a correction amount of the determination value to a value corresponding to a degree of change of the determination value over time. The operation unit calculates, at a first timing, a first value related to an average value of the determination values; and calculates, at a second timing later than the first timing, a second value related to the average value of the determination values. The degree of change of the determination value is calculated as a difference between the first value and the second value.

摘要： An engine ECU executes a program including the steps of: calculating a correlation coefficient K based on the result of comparing a vibration waveform of an engine and a knock waveform model stored previously; calculating a magnitude value LOG(V) from the magnitude V detected based on a signal transmitted from a knock sensor; creating frequency distribution of magnitude values LOG(V) by using magnitude values LOG(V) in an ignition cycle in which the correlation coefficient K larger than a threshold K(1) is calculated; and counting knock proportion KC by using the created frequency distribution. If the vibration waveform includes a waveform of vibration of noise components, the correlation coefficient K is calculated to be smaller comparing with a case of not including it.

摘要： In a torque control device for an internal combustion engine, a driving-system torque calculation unit calculates a driving-system torque operating on a driving system, based on a requested torque at a time of acceleration. A torque control unit executes torque control so that a gradient of the driving-system torque becomes equal to or smaller than a predetermined value, based on the driving-system torque calculated by the driving-system torque calculation unit. Thereby, since an amount of twist of the driving system can be maintained equal to or smaller than a predetermined value, repetitive shock can be suppressed, and acceleration shock can be effectively suppressed, too. Response deterioration and fuel consumption deterioration at the time of acceleration can be prevented.

摘要： The prevention of the occurrence of a shock during acceleration is enabled without impairing acceleration response as to a control apparatus for a vehicle driving unit. By changing a control amount of a specific one or specific ones of the plurality of the control elements when a torque-up request is issued, the output torque of the vehicle driving unit is increased toward a target output torque. In this case, a torque gradient upon changing the control amount of the specific one or the specific ones of the control elements is estimated and calculated on the basis of a current output torque of the vehicle driving unit according to a calculation rule formulated in advance. The control amounts of the respective control elements including the specific one or the specific ones of the control elements are set such that the estimated torque gradient coincides with a predetermined target torque gradient.
