摘要： An abnormality detection apparatus for a multi-cylinder internal combustion engine changes a fuel injection quantity of a predetermined target cylinder to detect an abnormality of an internal combustion engine based on values of rotational variations relating to the target cylinder detected before and after the change of the fuel injection quantity. The abnormality detection apparatus corrects the values of the rotational variations relating to the target cylinder detected before and after the change of the fuel injection quantity based on at least one of the number of revolutions of the engine and an engine load at a corresponding detection time.

摘要： An engine ECU calculates a rotational variation based on a required rotation time when a complete misfire occurs in a cylinder, a required rotation time when complete combustion occurs in the cylinder, and a required rotation time during the current combustion stroke, and integrates the calculated rotational variation. If it is determined that the number of times the rotational variation has been integrated has reached a predetermined number, the engine ECU calculates an amount of learning value deviation from the integrated rotational variation. If the amount of learning value deviation is equal to or greater than a certain amount, the engine ECU corrects a learning value of a sub-feedback control with respect to the air-fuel ratio.

摘要： This invention provides a mechanism for making a doctor surely follow correct procedures in which the doctor confirms diagnosis information obtained by computer processing after he or she has completed interpretation. A medical diagnosis support apparatus executes diagnosis processing for acquiring medical diagnosis information from an image to be interpreted by computer processing. The medical diagnosis support apparatus accepts interpretation information as an interpretation result of the image to be interpreted, which information is input by, for example, a doctor. The medical diagnosis support apparatus calculates a degree of matching between the diagnosis information and interpretation information, and permits to present the diagnosis information acquired by the diagnosis processing when the calculated degree of matching exceeds a predetermined threshold.

摘要： A vehicle includes an engine, a motor, a battery that stores an electric power for driving the motor, and a control apparatus. The control apparatus is configured to control the engine and the motor in one of control modes, the control mode includes a charge sustaining (CS) mode and a charge depleting (CD) mode. During the CS mode, a first determination is made to determine that the engine malfunction has occurred when a number of times of abnormal combustion occurring during a current trip is equal to or larger than a threshold. During the CD mode, instead of or in addition to the first determination, a second determination is made to determine that the engine malfunction has occurred when a cumulative number of times of abnormal combustion is equal to or larger than the threshold.
