摘要： PROBLEM TO BE SOLVED: To provide an anomaly determination device for accurately determining the occurrence of an abnormalities in a rotation sensor.
SOLUTION: A rotation sensor includes a main sensor and a sub-sensor wherein conditions are established that an output signal of the main sensor changes, in a state where an output signal of the sub-sensor is a high signal, each time a crankshaft rotates by a prescribed angle. When these conditions are established, in a state where there are no pulse signals being output from the rotation sensor, a pulse signal is output (at time t51 and t55) whose output width is a prescribed period TS, when the output signal of the main sensor falls, while a pulse signal is being output (time t52) whose output width is a prescribed period TL, that is longer than the prescribed period TS. Time intervals (T0, T1, and T2) between output start times of the respective pulse signals are calculated, while the rotation sensor is determined as being abnormal, when the difference between two consecutively calculated time intervals is larger than a determination value.

摘要： PROBLEM TO BE SOLVED: To appropriately determine the necessity of operation of an engine start device and suppress troubles of the start device being unnecessarily driven.
SOLUTION: An ECU 40 automatically stops an engine 10 when a prescribed automatic stop condition is established, and when a prescribed start condition is established during the automatic stop of the engine 10, automatically restarts the engine 10.

摘要： PROBLEM TO BE SOLVED: To provide a clutch operation position learning device capable of learning a disconnecting point of the clutch with high accuracy. SOLUTION: The device includes a clutch mechanism provided between an input shaft of a transmission and an output shaft of an internal combustion engine, and a clutch sensor for detecting an operation position of a clutch pedal (clutch opening CR); and learns a learning value GK1 of the disconnecting point of the clutch when the clutch pedal is operated in order to switch an operation state of the clutch mechanism from a non-connected state to a connected state.

摘要： PROBLEM TO BE SOLVED: To accurately determine whether knocking is caused or not by using a threshold value corresponding to engine vibration of an internal combustion engine. SOLUTION: An engine ECU executes a program including a step (S104) of detecting a vibration waveform of an engine, a step (S106) of calculating knock strength N corresponding to strength of the vibration waveform, and a step (S110) of calculating a correlation coefficient K(1) on a difference between a shape of a knock waveform model and a shape of the vibration waveform when the knock strength N is the threshold value NTR(1) or more (YES in S108). When the correlation coefficient K(1) is a threshold value K(2) or more, it is determined that the knocking is caused. When the knock strength N is smaller than the threshold value NTR(1) or when the correlation coefficient K(1) is smaller than the threshold value K(2), the vibration waveform is corrected so as to reduce a variation in the strength. The threshold value NTR(1) is set by using the strength of the corrected vibration waveform. COPYRIGHT: (C)2009,JPO&INPIT
