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： A throttle control apparatus comprises a throttle valve placed in an intake passage, a motor for driving the throttle valve, an electronic control unit (ECU) for controlling the motor, and a throttle sensor for detecting an actual opening degree of the throttle valve. The ECU determines that the throttle valve is frozen when the actual opening degree does not reach a target opening degree even after a driving time for driving the motor has exceeded a predetermined time, and then stores the actual opening degree at the time as an icing opening degree. The ECU supplies a driving duty to cause the motor to produce required driving torque for removal of icing and reverses the driving duty by open control, and controls the motor to bring an accumulated value of a deviation between the target opening degree and the icing opening degree to zero, thereby repeatedly swinging the throttle valve.

摘要： An engine ECU 200 includes a bandpass filter (1), a bandpass filter (2), and a bandpass filter (3). The bandpass filter (1) extracts only vibrations at a first frequency band A from the vibrations detected by a knock sensor. The bandpass filter (2) extracts only vibrations at a second frequency band B from the vibrations detected by the knock sensor. The bandpass filter (3) extracts only vibrations at a third frequency band C from the vibrations detected by the knock sensor. The first to third frequency bands A-C are identical in bandwidth. The engine ECU calculates a peak value in magnitude of vibrations in a synthesized waveform of these frequency bands, and determines whether knocking occurred or not based on the peak value.

摘要： An engine ECU executes a program including the steps of: comparing a vibration waveform of an engine and a knock waveform model stored in advance to calculate a correlation coefficient K; prohibiting correction when a correction prohibiting condition of a determination value V(KX) is satisfied, the determination value V(KX) compared with a knock magnitude N calculated from the correlation coefficient K so as to control the ignition timing; and correcting the determination value V(KX) based on a magnitude value LOG(V) calculated from a magnitude V of vibration in an ignition cycle in which the correlation coefficient K greater than a threshold value K(1) is calculated when the correction prohibiting condition of determination value V(KX) is not satisfied. The correlation coefficient K is calculated as a smaller value when the vibration waveform includes a waveform of vibration of a noise component as compared with that when the vibration waveform does not include it.

摘要： A traction control system controls the engine torque so as to prevent wheel slip during acceleration. The system has an electric control unit ECU which detects the state of wheel slip on the basis of the deviation of the drive wheel speed from a target drive wheel speed computed in accordance with signals from various sensors such as drive wheel speed sensors, trailing wheel speed sensors, shift position sensor for sensing the shift position in an electronic control transmission ECT, engine speed sensor and accelerator sensor for sensing the amount of operation of accelerator. The ECU computes, in accordance with the state of the slip, a limit drive torque which does not allow surplus wheel slip during acceleration. The ECU also updates the limit drive torque depending on whether the surplus slip takes place on drive wheels, and detects also the amount of operation of the accelerator so as to inhibit updating of the limit drive torque when the detected amount of operation of accelerator is below a value corresponding to a limit throttle opening, whereby the engine is controlled such that the drive torque applied to the drive wheels is maintained below the limit drive torque.
