摘要： An engine ECU executes a program including the steps of: detecting a vibration corresponding to a first radial resonance mode by using a band-pass filter, from vibrations sensed by an in-cylinder pressure sensor provided at an upper central portion of the cylinder; calculating knock intensity N based on a result of comparison between the detected waveform and a knock waveform model prepared in advance as a vibration waveform when knocking occurs; determining that knocking occurred when the knock intensity N is larger than a predetermined reference value; and determining that knocking has not occurred when the knock intensity N is not larger than the predetermined reference value.

The engine ECU determines whether the engine knocks, as based on the vibration selected by means of the bandpass filter or bandpass filter.

摘要： An output of a knock sensor is A/D converted in a specified knock determination range. In a time-frequency analysis part, data of frequency, time, and vibration intensity are extracted at the same time from the knock sensor output signal and the time-varying patterns of vibration intensities in multiple frequency ranges are extracted. An edge direction and an edge intensity are computed by an edge extraction processing. A correlation value expressing a correlation between time-varying patterns of vibration intensities in multiple frequency ranges and a reference model expressing the feature of knock is computed in a mutual correlation/knock determination part. The correlation value is compared with a determination threshold. When the correlation value is larger than the determination threshold, it is determined that knock is caused. When the correlation value is not larger than the determination threshold, it is determined that knock is not caused.

摘要： A fluid brake device has a brake shaft which penetrates a case. The case provides a fluid chamber for a magneto-rheological fluid. A magnetic seal has a magnetic seal sleeve which holds a small amount of the magneto-rheological fluid by magnetic flux. In addition to the magnetic seal, an axially pumping element is provided on an axial outside of the magnetic seal. The axially pumping element is provided by a shaft helical groove formed on an opposing wall of the brake shaft and/or a case helical groove formed on a surrounding wall. As the brake shaft rotates, the helical groove pushes the magneto-rheological fluid back to the magnetic seal. A combination of the magnetic seal and the axially pumping element may reduce leakage of the magneto-rheological fluid.

摘要： An output signal of a knock sensor is converted by an A/D conversion part in a specified knock determination range. In a time-frequency analysis part, data of frequency, time, and vibration intensity are extracted at the same time from an output signal of the knock sensor, and the time-varying patterns of vibration intensities in multiple frequency ranges are extracted. A knock determination part computes the number of time-varying patterns of vibration intensity which rise at same time. The knock determination part executes a knock determination based on whether the number of the time-varying patterns of vibration intensity is greater than a knock determination threshold.

摘要： A fluid brake device has a case defining a fluid chamber. Magneto-rheological fluid is contained in the fluid chamber. A brake member is rotatably supported on the case and receives a braking torque according to the viscosity of the magneto-rheological fluid. The device has a movable member driven by a thermo-sensitive wax so that a volume of the fluid chamber is increased as the temperature in the fluid chamber is increased. The movable member is driven to maintain a pressure in the fluid chamber within an allowable range when the temperature in the fluid chamber is changed.
